Description
본 발명은 냉각액 조성물에 관한 것이다. 보다 상세하게는, 본 발명은 냉동기, 제빙기, 또는 다양한 냉각장치 등의 낮은 온도에서 사용되는 냉각액 조성물, 및 자동차 엔진 냉각시스템을 냉각시키는데 사용되는 냉각액 조성물에 관한 것이다.The present invention relates to a coolant composition. More specifically, the present invention relates to a coolant composition used at low temperatures, such as a refrigerator, ice maker, or various chillers, and a coolant composition used to cool an automotive engine cooling system.
일본특허출원 제1-103684호(미심사)는 이러한 종류의 냉각 유체(cooling fluid)를 개시하고 있다. 상기 유체는 냉각에 저항성이 있다. 상기 유체는 주요성분으로 물 3-6중량부(parts by weight), 요소 0.5-1.5중량부, 글리콜 1.5중량부 이하, 포름산 나트륨 1-2중량부, 및 아세트산 나트륨 1-2 중량부를 포함한다. 선택적으로, 상기 유체는 주요성분으로 아세트산칼륨 4-7중량부, 포름산칼륨 1.5중량부 이하, 및 물 3-9중량부를 포함한다.Japanese Patent Application No. 1-103684 (unexamined) discloses this kind of cooling fluid. The fluid is resistant to cooling. The fluid contains, as a main component, 3-6 parts by weight of water, 0.5-1.5 parts by weight of urea, 1.5 parts by weight or less of glycol, 1-2 parts by weight of sodium formate, and 1-2 parts by weight of sodium acetate. Optionally, the fluid contains 4-7 parts by weight of potassium acetate, 1.5 parts by weight or less of potassium formate, and 3-9 parts by weight of water.
나아가, 상기 유체는 바람직하게는 항부식제(anticorrosive)를 0.1-1.0중량% 농도로 함유한다. 상기 항부식제는 벤조산, 벤조산나트륨, 벤조산칼륨, 및 벤조트리아졸(benzotriazole)로 구성된 군으로부터 선택된 하나 이상의 화합물을 포함한다.Furthermore, the fluid preferably contains 0.1 to 1.0% by weight of anticorrosive. The anticorrosive includes one or more compounds selected from the group consisting of benzoic acid, sodium benzoate, potassium benzoate, and benzotriazole.
상기 유체는 열 전기발전소의 냉각탑, 산업용 또는 가정용 냉동기 및 급속 냉동기, 개방형 또는 폐쇄형의 열교환기, 태양열 수집기, 증폭기, 및 화학공장 가압멸균기와 같은 시스템에서 사용될 수 있다. 상기 시스템이 작동되면, 상기 유체는 냉각과 관련된 문제들을 피할 수 있도록 냉각에 저항성이 있다. 또한, 상기 유체는 글리콜없이 조성될 수도 있다. 글리콜이 배제되면 상기 유체는 환경을 오염시키지 않고 그것이 사용되는 시스템의 내구성을 개선시킨다.The fluids can be used in systems such as cooling towers of thermoelectric power plants, industrial or domestic freezers and rapid freezers, open or closed heat exchangers, solar collectors, amplifiers, and chemical plant autoclaves.

본 발명의 다른 측면 및 잇점은 본 발명의 원리를 예시적으로 설명하는 하기 발명의 상세한 설명으로부터 명확해질 것이다.Other aspects and advantages of the invention will be apparent from the following detailed description of the invention illustrating the principles of the invention.
본 발명 조성물의 제1 구현예를 상세히 설명하고자 한다.The first embodiment of the composition of the present invention will be described in detail.
제1 구현예의 조성물은 포름산염과 물을 포함하는 주요성분과 인산, 인산염, 또는 이들의 조합물 및 트리아졸화합물을 포함하는 항부식제를 포함한다. 상기 조성물은 주로 냉동기, 제빙기, 또는 다른 다양한 냉각장치에서 저온 냉각액으로 사용된다. 상기 조성물은 바람직하게는 약 -55℃부터 약 -20℃의 온도 범위에서 사용될 수 있다. 상기 조성물은 심지어 약 -20℃부터 약 100℃ 범위의 온도에서 이로운 냉각 특성을 갖는다. 그러므로, 상기 조성물은 또한 자동차 엔진의 냉각 시스템을 냉각시키기 위한 냉각액으로 사용가능하다.The composition of the first embodiment comprises an anticorrosive agent comprising a main component comprising formate and water and a phosphoric acid, phosphate, or a combination thereof and a triazole compound. The composition is mainly used as a low temperature coolant in a refrigerator, ice maker, or various other chillers. The composition may preferably be used in a temperature range of about -55 ° C to about -20 ° C. The composition even has advantageous cooling properties at temperatures ranging from about -20 ° C to about 100 ° C. Therefore, the composition can also be used as a coolant for cooling the cooling system of an automobile engine.
상기 조성물은 포름산염을 포함한다. 포름산염은 항냉각 성분으로 사용된다. 포름산염이 용해된 용액은 매우 큰 어는점 내림현상(freezing point depression)을 나타낸다. 게다가, 포름산염 용액의 점도는 약 -55℃부터 약 -20℃ 범위의 온도로 냉각되어도 유의성있게 증가하지는 않는다. 포름산염은 부식성, 휘발성 및 가연성 (flammable)이 덜하다.The composition comprises formate. Formate is used as an anticooling component. Formate-dissolved solutions show very large freezing point depression. In addition, the viscosity of the formate solution does not significantly increase when cooled to a temperature ranging from about -55 ° C to about -20 ° C. Formate is less corrosive, volatile and flammable.
포름산염 중에서, 포름산나트륨과 포름산칼륨이 바람직하다. 이들 알칼리 금속염은 물에서의 용해도가 좋다. 포름산나트륨은 물에서의 용해도가 매우 좋기때문에 가장 바람직하다. 상기 포름산염은 포름산을 함유한 조성물에 수산화나트륨 또는 수산화칼륨을 첨가하고 pH를 조정함으로써 제조될 수 있다. 조성물내 포름산염의 농도는 상기 조성물이 사용되는 온도에 기초하여 적절히 선택된다. 바람직하게는, 포름산염 농도는 30중량% 내지 60중량% 범위이다. 포름산염 농도가 30중량% 이하이면, 상기 조성물은 15℃이하에서 냉각된다. 반면에, 포름산염 농도가 60중량% 이상이면, 상기 조성물은 비균일 액체가 된다.Of the formates, sodium formate and potassium formate are preferred. These alkali metal salts have good solubility in water. Sodium formate is most preferred because it has very good solubility in water. The formate can be prepared by adding sodium or potassium hydroxide to the composition containing formic acid and adjusting the pH. The concentration of formate in the composition is appropriately selected based on the temperature at which the composition is used. Preferably, the formate concentration is in the range of 30% to 60% by weight. If the formate concentration is 30% by weight or less, the composition is cooled below 15 ° C. On the other hand, if the formate concentration is 60% by weight or more, the composition becomes a non-uniform liquid.
상기 조성물은 또한 항부식제를 포함한다. 상기 항부식제는 열교환기, 순환 파이프, 냉각장치내 냉각 시스템을 형성하는 연결부의 금속 부식을 방지한다. 영향을 받을 수 있는 금속은 철, 강철, 구리, 청동, 알류미늄, 및 알류미늄 합금을 포함한다. 상기 항부식제는 인산, 인산염, 또는 이들의 조합물 및 티아졸 화합물을 포함한다.The composition also includes an anticorrosive agent. The anticorrosive prevents metal corrosion of the heat exchanger, circulation pipes, and connections forming the cooling system in the chiller. Metals that may be affected include iron, steel, copper, bronze, aluminum, and aluminum alloys. The anticorrosive includes phosphoric acid, phosphate, or combinations thereof and thiazole compounds.
인산, 인산염, 및 이들의 조합물은 철, 구리 및 알류미늄을 함유하는 금속의 부식을 주로 방지한다. 인산, 인산염, 또는 이들 조합물의 예로는 인산, 인산 이나트륨(disodium phosphate), 인산 이칼륨(dipotassium phosphate), 수소화인산 나트륨(sodium hydrogenphosphate), 수소화인산 칼륨(potassium hydrogenphosphate)이 있다. 조성물내 인산, 인산염, 또는 이들 조합물의 농도는 0.01 내지 1.0중량% 범위이다. 인산, 인산염, 이들 조합물의 농도가 0.01중량% 이하이면, 상기 조성물은 철, 구리, 및 알류미늄 금속의 부식을 충분히 방지하지 못한다. 반면에, 인산, 인산염, 또는 이들 조합물의 농도가 1.0중량% 이상이면, 조성물내에서 충분히 용해되지 못한다.Phosphoric acid, phosphates, and combinations thereof mainly prevent corrosion of metals containing iron, copper, and aluminum. Examples of phosphoric acid, phosphates, or combinations thereof include phosphoric acid, disodium phosphate, dipotassium phosphate, sodium hydrogenphosphate, and potassium hydrogenphosphate. The concentration of phosphoric acid, phosphate, or combinations thereof in the composition ranges from 0.01 to 1.0% by weight. If the concentration of phosphoric acid, phosphate, or a combination of these is 0.01% by weight or less, the composition does not sufficiently prevent corrosion of iron, copper, and aluminum metal. On the other hand, when the concentration of phosphoric acid, phosphate, or combinations thereof is 1.0 wt% or more, it is not sufficiently dissolved in the composition.
트리아졸 화합물은 구리 함유 금속의 부식을 주로 방지한다. 트리아졸 화합물의 예는 벤조트리아졸(benzotriazole) 및 토일트리아졸(tolytriazole)이다. 조성물내 상기 트리아졸 화합물의 농도는 0.01 내지 0.5중량%이다. 상기 화합물의 농도가 0.01중량% 이하이면, 상기 조성물은 구리 함유 금속의 부식을 충분히 방지하지 못한다. 반면에, 상기 화합물의 농도가 0.5%중량 이상이면, 상기 화합물은 조성물내에서 충분히 용해되지 못한다.Triazole compounds primarily prevent corrosion of copper containing metals. Examples of triazole compounds are benzotriazole and tolytriazole. The concentration of the triazole compound in the composition is 0.01 to 0.5% by weight. If the concentration of the compound is 0.01% by weight or less, the composition does not sufficiently prevent corrosion of the copper-containing metal. On the other hand, when the concentration of the compound is 0.5% by weight or more, the compound is not sufficiently dissolved in the composition.
나아가, 상기 조성물은 티아졸 화합물; 붕산(boric acid), 붕산염, 또는 이들의 조합물; 및 몰리브덴산(molybdic acid), 몰리브덴산염, 또는 이들의 조합물로 구성된 군으로부터 선택된 하나 이상의 항부식제를 포함한다.Further, the composition may comprise a thiazole compound; Boric acid, borates, or combinations thereof; And one or more anticorrosive agents selected from the group consisting of molybdic acid, molybdate, or combinations thereof.
티아졸 화합물은 주로 구리 함유 금속의 부식을 방지하는데 효과적이다. 티아졸 화합물의 예로는 머켑토벤조티아졸, 그의 나트륨염, 및 그의 칼륨염 등이 있다. 티아졸 화합물의 농도는 바람직하게는 0.01 내지 1.0중량% 범위이다. 티아졸 화합물의 농도가 0.01중량% 이하이면, 상기 조성물은 구리 함유 금속의 부식을 효과적으로 방지하지 못한다. 반면에, 티아졸 화합물의 농도가 1.0중량% 이상이면, 상기 티아졸 화합물은 조성물내에 충분히 용해되지 못한다.Thiazole compounds are mainly effective in preventing corrosion of copper containing metals. Examples of thiazole compounds include mercetobenzothiazole, its sodium salt, its potassium salt and the like. The concentration of the thiazole compound is preferably in the range of 0.01 to 1.0% by weight. If the concentration of the thiazole compound is 0.01% by weight or less, the composition does not effectively prevent corrosion of the copper-containing metal. On the other hand, when the concentration of the thiazole compound is 1.0% by weight or more, the thiazole compound is not sufficiently dissolved in the composition.
붕산, 붕산염, 및 이들의 조합물은 주로 철 함유 금속의 부식 방지에 효과적이다. 붕산, 붕산염, 및 이들 조합물의 예로는 붕산, 붕산 나트륨, 및 붕산 칼륨등이 있다.Boric acid, borate salts, and combinations thereof are mainly effective in preventing corrosion of iron-containing metals. Examples of boric acid, borate salts, and combinations thereof include boric acid, sodium borate, and potassium borate.
조성물내 붕산, 붕산염, 또는 이들의 조합물 농도는 바람직하게는 0.01 내지 1.0중량% 범위이다. 붕산, 붕산염, 또는 이들 조합물의 농도가 0.01중량% 이하이면, 상기 조성물은 철 함유 금속의 부식을 효과적으로 방지하지 못한다. 반면에, 붕산, 붕산염, 또는 이들의 조합물이 1.0중량% 이상이면, 조성물내에 충분히 용해되지 못한다.The concentration of boric acid, borate, or combination thereof in the composition is preferably in the range of 0.01 to 1.0% by weight. If the concentration of boric acid, borate, or combinations thereof is 0.01% by weight or less, the composition does not effectively prevent corrosion of the iron-containing metal. On the other hand, if boric acid, borate, or a combination thereof is 1.0 wt% or more, it will not be sufficiently dissolved in the composition.
몰리브덴산, 몰리브덴산염, 및 이들의 조합물은 철 함유 금속의 부식을 방지하는데 주로 효과적이다. 몰리브덴산, 몰리브덴산염, 및 이들 조합물의 예로는 몰리브덴산, 몰리브덴산나트륨, 및 몰리브덴산칼륨 등이 있다. 몰리브덴산, 몰리브덴산염, 또는 이들 조합물의 농도는 바람직하게는 0.01 내지 1.0중량% 범위이다. 몰리브덴산, 몰리브덴산염, 또는 이들 조합물의 농도가 0.01중량% 이하이면, 상기 조성물은 철 함유 금속의 부식을 효과적으로 방지하지 못한다. 반면에, 몰리브덴산, 몰리브덴산염, 또는 이들 조합물의 농도가 1.0중량% 이상이면, 조성물내에서 충분히 용해되지 못한다.Molybdate, molybdate, and combinations thereof are mainly effective in preventing corrosion of iron containing metals. Examples of molybdate, molybdate, and combinations thereof include molybdate, sodium molybdate, potassium molybdate and the like. The concentration of molybdate, molybdate, or combinations thereof is preferably in the range from 0.01 to 1.0% by weight. If the concentration of molybdate, molybdate, or combinations thereof is 0.01% by weight or less, the composition does not effectively prevent corrosion of the iron-containing metal. On the other hand, when the concentration of molybdate, molybdate, or a combination of these is 1.0 wt% or more, it is not sufficiently dissolved in the composition.
조성물은 조성물을 착색시키기 위한 착색제(colorant), 거품 형성을 억제하기 위한 소포제, 우연한 가음(accidental drinking)을 방지하기 위한 산미제 (bitter agent) 또는 이들의 조합물을 포함한다. 착색제의 예에는 타트라진 (Tartrazine), 우라닌 콩크(Uranine Conc.), 액시드 그림 25(Acid Green 25), 및 페놀 레드 등이 포함된다. 소포제의 예에는 실리콘 소포제, 폴리에테르 소포제, 및 고분자 알코올 소포제 등이 포함된다. 산미제의 예로는 디나토니움 벤조에이트 (denatonium benzoate)가 있다.The composition comprises a colorant for coloring the composition, an antifoaming agent for inhibiting foam formation, a bitter agent for preventing accidental drinking or a combination thereof. Examples of colorants include tarrazine, Uranine Conc., Acid Green 25, phenol red, and the like. Examples of the antifoaming agent include a silicone antifoaming agent, a polyether antifoaming agent, a polymer alcohol antifoaming agent, and the like. An example of an acidulant is denatonium benzoate.
조성물의 항부식제 효과를 강화하기 위해서, 상기 조성물은 바람직하게는 pH 7-11로 조정된다. pH가 7 이하이면, 상기 조성물은 철 함유 금속의 부식을 용이하게 할 수 있다. pH가 11 이상이면, 상기 조성물은 구리 함유 금속의 부식을 용이하게 할 수 있다. 또한, 상기 조성물은 바람직하게는 알칼리 금속염을 포함한다. 바람직하게는, 조성물내에서 하나 이상의 포름산염, 인산염, 트리아졸 화합물, 붕산염, 및 몰리브덴산염이 금속염이다. 상기 알칼리 금속염은 불용성 물질의 생성을 억제한다.In order to enhance the anticorrosive effect of the composition, the composition is preferably adjusted to pH 7-11. If the pH is 7 or less, the composition can facilitate the corrosion of the iron-containing metal. If pH is 11 or more, the said composition can facilitate the corrosion of a copper containing metal. In addition, the composition preferably comprises an alkali metal salt. Preferably, at least one of the formate, phosphate, triazole compound, borate, and molybdate in the composition is a metal salt. The alkali metal salt inhibits the production of insoluble matters.
제1 구현예의 조성물은 포름산염 및 물을 포함하는 주요성분, 및 인산, 인산염, 또는 이들 조합물 및 트리아졸을 포함하는 항부식제를 포함한다.The composition of the first embodiment comprises an active ingredient comprising formate and water, and an anticorrosive agent comprising phosphoric acid, phosphate, or a combination thereof and triazole.
포름산염 용액은 매우 큰 어는 점 내림 현상을 나타내며 포름산염 용액의 점도는 온도가 내려가면 충분히 증가하지 않는다. 그러므로, 포름산염은 조성물의 항냉각 성분(antifreeze component)으로 사용하는데 매우 적합하다. 포름산염은 또한 우수한 냉각 특성을 갖는다.The formate solution shows a very large freezing point drop and the viscosity of the formate solution does not increase sufficiently as the temperature decreases. Therefore, formate is very suitable for use as an antifreeze component of the composition. Formate also has good cooling properties.
통상적으로, 항냉각성분으로는 칼슘 수산화물(calcium hydride), 에틸렌글리콜, 프로필렌글리콜, 알코올화합물, 및 플루오르화합물이 사용되어져 왔다.Typically, calcium hydroxide (calcium hydride), ethylene glycol, propylene glycol, alcohol compounds, and fluorine compounds have been used as the anti-cooling component.
포름산염은 칼슘 수산화물보다도 부식성이 훨씬 덜하다. 그러므로, 냉각 시스템의 일부를 형성하는 금속은 쉽게 부식되지 않는다.Formate is much less corrosive than calcium hydroxide. Therefore, the metal forming part of the cooling system is not easily corroded.
포름산염을 함유한 용액의 점도는 에틸렌글리콜 또는 프로필렌글리콜을 함유한 용액에 비교하여 낮은 온도에서 충분히 증가하지 않는다. 그러므로, 냉각 시스템 내에서 용액은 부드럽게 순환한다. 이것이 냉각 시스템을 형성하는 순환 파이프에서의 기계적 부담을 경감시킨다. 게다가, 시스템내의 열 손실을 감소시키기 위하여 파이프의 직경은 더 작게 만들어질 수 있다(그러므로, 표면적은 더 작아질 수 있다).The viscosity of the solution containing formate does not increase sufficiently at low temperatures as compared to the solution containing ethylene glycol or propylene glycol. Therefore, the solution circulates smoothly in the cooling system. This alleviates the mechanical burden on the circulation pipe forming the cooling system. In addition, the diameter of the pipe can be made smaller (thus the surface area can be made smaller) in order to reduce the heat loss in the system.
포름산염은 생분해가능하다. 그러므로 포름산염은 에틸렌글리콜 및 프로필렌글리콜보다 오염성이 적다. 제1 구현예 조성물의 화학적 산소요구량(C.O.D) 및 생물학적 산소요구량(B.O.D)은 에틸렌글리콜 및/또는 프로필렌글리콜을 함유한 조성물에 비해 1/20 이하이다. 포름산염은 조성물의 환경오염 효과를 현저히 개선시킨다.Formate is biodegradable. Therefore, formate is less contaminated than ethylene glycol and propylene glycol. The chemical oxygen demand (C.O.D) and biological oxygen demand (B.O.D) of the composition of the first embodiment are 1/20 or less compared to the composition containing ethylene glycol and / or propylene glycol. Formate significantly improves the environmental pollution of the composition.
포름산염 용액은 휘발성이 훨씬 적다. 반면에, 알코올화합물 및 플루오르화합물은 매우 휘발성이 있어서 이들을 함유한 조성물은 증발로 인한 손실을 보상하기 위해서 빈번히 보충되어져야만 한다. 포름산염을 함유한 조성물은 빈번히 보충할 필요가 없다. 이것이 바로 시스템 유지를 용이하게 한다.Formate solutions are much less volatile. On the other hand, alcoholic and fluorine compounds are very volatile and compositions containing them must be frequently replenished to compensate for the loss due to evaporation. Compositions containing formate do not need to be replenished frequently. This facilitates system maintenance.
포름산염은 연소성이 훨씬 적다. 반면에, 알코올화합물은 매우 연소성이 있어서 냉각시스템을 고안하고 제조하는데 있어서 화재 안전을 위한 주의깊은 대책이 강구되어져야만 한다. 포름산 용액이 사용될시는 그러한 특별한 화재 안전대책은 불필요하다. 이것은 냉각시스템의 고안 및 제조를 용이하게 한다. 게다가, 포름산염은 플로오르화합물에 비해 가격이 더 싸다.Formate is much less combustible. On the other hand, alcohol compounds are very combustible and careful measures for fire safety must be taken in the design and manufacture of cooling systems. When formic acid solution is used, such special fire safety measures are not necessary. This facilitates the design and manufacture of the cooling system. In addition, formate is less expensive than fluoro compounds.
30 내지 60중량%의 포름산염은 조성물의 개선된 냉각특성을 확실히 보장한다.30 to 60% by weight of formate ensures improved cooling properties of the composition.
포름산칼륨은 물에서 매우 우수한 용해도를 나타내어, 조성물은 매우 높은 농도로 상기 화합물을 함유할 수 있다. 조성물의 냉각 특성은 용액내에 더 많은 포름산칼륨이 용해될 수 있을 정도만큼 개선될 수 있다. 이것은 낮은 온도에서 조성물이 사용가능하게 한다.Potassium formate shows very good solubility in water so that the composition can contain the compound in very high concentrations. The cooling properties of the composition can be improved to the extent that more potassium formate can be dissolved in the solution. This makes the composition usable at low temperatures.
인산, 인산염, 또는 이들 조합물, 및 트리아졸 화합물은 철, 구리, 알류미늄 함유 금속에 대해 매우 높은 항부식효과를 발휘한다. 상기 화합물들은 그러한 금속으로 구성된 냉각시스템의 부분에 대한 부식을 효과적으로 방지한다. 그러므로, 부식산물은 상기 조성물에서는 생기지 않는다. 이것은 냉각시스템의 순환파이프 막힘을 방지한다. 따라서, 냉각장치는 거의 아무런 문제없이 장기간 작동이 가능한데, 이것이 시스템 유지비를 감소시킨다.Phosphoric acid, phosphates, or combinations thereof, and triazole compounds exert very high anticorrosive effects on iron, copper and aluminum containing metals. The compounds effectively prevent corrosion of parts of the cooling system composed of such metals. Therefore, no corrosive product occurs in the composition. This prevents clogging of the circulation pipe of the cooling system. Therefore, the chiller can be operated for a long time with almost no problem, which reduces the system maintenance cost.
조성물내 인산, 인산염, 또는 이들 조합물의 농도는 0.01 내지 1.0중량% 범위이다. 조성물내 트리아졸 화합물의 농도는 0.01 내지 0.5중량% 범위이다. 항부식화합물의 이들 농도는 금속 부식을 방지하고 및 조성물내 용해가 확실히 일어나게 한다.The concentration of phosphoric acid, phosphate, or combinations thereof in the composition ranges from 0.01 to 1.0% by weight. The concentration of triazole compound in the composition is in the range of 0.01 to 0.5% by weight. These concentrations of anticorrosive compounds prevent metal corrosion and ensure dissolution in the composition.
트리아졸 화합물의 사용은 구리 함유 금속에 대한 조성물 항부식효과를 개선시킨다. 0.01 내지 1.0중량%에 달하는 양의 트리아졸 화합물은 충분한 항부식 효과를 제공하고 조성물내 용해가 확실히 일어나게 한다.The use of triazole compounds improves the composition anticorrosive effect on copper containing metals. Triazole compounds in amounts of from 0.01 to 1.0% by weight provide a sufficient anticorrosive effect and ensure dissolution in the composition.
붕산, 붕산염, 및 이들의 조합물을 사용하는 것은 철 함유 금속의 항부식 효과를 개선시킨다. 0.01 내지 1.0중량%에 달하는 붕산, 붕산염, 또는 이들의 조합물의 사용은 충분한 항부식 효과를 제공하고 조성물내 용해가 확실히 일어나게 한다.Using boric acid, borate salts, and combinations thereof improves the anticorrosive effect of iron containing metals. The use of boric acid, borate, or combinations thereof of from 0.01 to 1.0% by weight provides a sufficient anticorrosive effect and ensures dissolution in the composition.
몰리브덴산, 몰리브덴산염, 또는 이들의 조합물은 철 함유 금속의 항부식효과를 개선시킨다. 0.01 내지 1.0중량%에 달하는 몰리브덴산, 몰리브덴산염, 또는 이들 조합물은 충분한 항부식효과를 제공하고 조성물내 용해가 확실히 일어나게 한다.Molybdate, molybdate, or a combination thereof improves the anticorrosive effect of the iron containing metal. Molybdenic acid, molybdate, or a combination thereof of from 0.01 to 1.0% by weight provides a sufficient anticorrosive effect and ensures dissolution in the composition.
Ph 7-11로 조정된 조성물은 철 함유 금속 및 구리함유 금속의 항부식효과를 개선시킨다.The composition adjusted to Ph 7-11 improves the anticorrosive effect of the iron containing metals and the copper containing metals.
조성물내 알칼리 금속염의 사용은 불용성 물질의 생성을 억제한다. 알칼리금속염의 사용은 조성물의 항부식효과를 개선시킨다.The use of alkali metal salts in the composition inhibits the production of insoluble materials. The use of alkali metal salts improves the anticorrosive effect of the composition.
제1 구현예와는 다른 관점에 촛점을 맞추어 본 발명 제2 구현예 조성물을 설명하고자 한다.The second embodiment composition of the present invention will be described focusing on a different point from the first embodiment.
제2 구현예 조성물은 포름산염 및 물을 포함하는 주요성분, 및 지방족 카르복실산 화합물 및 트리아졸 화합물을 포함하는 항부식제를 포함한다. 지방족 카르복실산 화합물(aliphatic carboxylic compound)은 1)C10-C22지방족 2가 카르복실산 (aliphatic dicarboxylic acid), 2)C7-C9지방족 1가 카르복실산(aliphatic monocarboxylic acid), 3) 상기 1) 또는 2)의 무수화물(anhydride), 및 4) 상기 1) 또는 2)의 알칼리금속염으로 구성된 군으로부터 선택된다. 제2 구현예의 화합물은 자동차 엔진의 냉각시스템을 냉각시키기 위한 냉각액으로 주로 사용된다. 조성물은 약-55℃ 내지 약0℃ 범위의 낮은 온도에서 냉각을 방지한다. 상기 조성물은 약 0℃ 내지 약100℃ 범위의 비교적 높은 온도에서조차도 이로운 냉각특성을 나타낸다. 제2 구현예의 조성물은 또한 제1 구현예의 조성물과 같이 냉각장치의 냉각액으로 사용될 수 있다.The second embodiment composition comprises a main component comprising formate and water, and an anticorrosive agent comprising an aliphatic carboxylic acid compound and a triazole compound. Aliphatic carboxylic compounds include 1) C 10 -C 22 aliphatic dicarboxylic acids, 2) C 7 -C 9 aliphatic monocarboxylic acids, 3 A) anhydride of 1) or 2), and 4) an alkali metal salt of 1) or 2). The compound of the second embodiment is mainly used as a coolant for cooling the cooling system of an automobile engine. The composition prevents cooling at low temperatures in the range of about-55 ° C to about 0 ° C. The composition exhibits beneficial cooling properties even at relatively high temperatures in the range of about 0 ° C to about 100 ° C. The composition of the second embodiment can also be used as the coolant of the chiller like the composition of the first embodiment.
조성물은 포름산염을 포함한다. 포름산염은 조성물의 어는점을 낮추기 위한 항냉각 성분으로 사용될 수 있다. 포름산염은 자동차 엔진 냉각시스템이 냉각액의 냉각에 의해 파괴되는 것을 방지한다. 포름산염 농도는 조성물이 사용되는 온도에 기초하여 적절히 결정된다. 바람직하게는, 포름산염 농도는 20 내지 60중량%이고, 보다 바람직하게는 30 내지 60중량%이다. 포름산염 농도가 20중량% 이하이면, 조성물은 10℃이하에서 얼 수 있다. 반면에, 포름산염 농도가 60중량% 이상이면, 조성물은 비균일 유체가 될 수 있다.The composition comprises formate. Formate can be used as an anti-cooling component to lower the freezing point of the composition. Formate prevents the automobile engine cooling system from being destroyed by the cooling of the coolant. The formate concentration is appropriately determined based on the temperature at which the composition is used. Preferably, the formate concentration is 20 to 60% by weight, more preferably 30 to 60% by weight. If the formate concentration is 20% by weight or less, the composition can be frozen at 10 ° C or less. On the other hand, if the formate concentration is 60% by weight or more, the composition can be a non-uniform fluid.
조성물은 또한 항부식제를 포함한다. 항부식제는 엔진 냉각시스템 금속의 부식을 방지한다. 영향을 받을 수 있는 금속은 알류미늄, 알류미늄 합금, 캐스트 철, 강철, 청동, 납과 주석 합금(solder) 및 구리를 포함한다. 항부식제는 1)C10-C22지방족 2가 카르복실산, 2)C7-C9지방족 1가 카르복실산, 3) 상기 1) 또는 2)의 무수화물, 및 4) 상기 1) 또는 2)의 알칼리 금속염을 포함한다.The composition also includes an anticorrosive agent. Anticorrosive prevents corrosion of metals in engine cooling systems. Metals that may be affected include aluminum, aluminum alloys, cast iron, steel, bronze, lead and tin alloys and copper. The anticorrosive is 1) C 10 -C 22 aliphatic dicarboxylic acid, 2) C 7 -C 9 aliphatic monocarboxylic acid, 3) anhydride of 1) or 2) above, and 4) 1) or The alkali metal salt of 2) is included.
본 명세서에 사용된 것처럼, 지방족 카르복실 화합물(aliphatic carboxylic compound)은 1)C10-C22지방족 2가 카르복실산(aliphatic dicarboxylic acid), 2)C7-C9지방족 1가 카르복실산(aliphatic monocarboxylic acid), 3) 상기 1) 또는 2)의 무수화물(anhydride), 및 4) 상기 1) 또는 2)의 알칼리금속염으로 구성된 군으로부터 선택된 하나 이상의 화합물을 나타낸다. 상기 지방족 카르복실 화합물은 철, 구리, 또는 알류미늄 함유 금속에 대해 우수한 항부식효과를 나타낸다.As used herein, aliphatic carboxylic compounds include 1) C 10 -C 22 aliphatic dicarboxylic acids, 2) C 7 -C 9 aliphatic monocarboxylic acids ( aliphatic monocarboxylic acid), 3) anhydrides of 1) or 2), and 4) alkali metal salts of 1) or 2). The aliphatic carboxyl compound exhibits an excellent anticorrosive effect on iron, copper, or aluminum containing metals.
예컨대, C10-C22지방족 2가 카르복실산(aliphatic dicarboxylic acid)은 세박산(sebasic acid), 도데칸디온산(dodecanedioic acid), 옥테닐숙신산(octenyl succinic acid), 도데세닐숙신산(dodecenyl succinic acid), 테트라데세닐 숙신산 (tetradecenyl succinic acid), 펜타데세닐숙신산(pentadecenyl succinic acid), 또는 옥타데세닐숙신산(octadecenyl succinic acid)일 수 있다. 지방족 2가 카르복실산의 탄소원자수가 10이하이면, 금속에 대한 항부식효과는 현저히 감소된다. 반면에, 지방족 2가 카르복실산내 탄소원자수가 22이상이면, 조성물내 용해도는 현저히 감소한다.For example, C 10 -C 22 aliphatic dicarboxylic acid (aliphatic dicarboxylic acid) is sebasic acid (dobasic acid), dodecanedioic acid (dodecanedioic acid), octenyl succinic acid, dodecenyl succinic acid ), Tetratradecenyl succinic acid, pentadecenyl succinic acid, or octadecenyl succinic acid. If the aliphatic divalent carboxylic acid has 10 or less carbon atoms, the anticorrosive effect on the metal is significantly reduced. On the other hand, when the number of carbon atoms in the aliphatic divalent carboxylic acid is 22 or more, the solubility in the composition is markedly reduced.
예컨대, C7-C9지방족 카르복실산은 에난트산(enanthic acid), 옥틸산 (octylic acid), 또는 카프릴산(caprylic acid)일 수 있다. 지방족 카르복실산내 탄소원자수가 7이하이면, 높은 휘발성을 나타낸다. 이로 인해, 상기 화합물을 취급하는데 어려움이 있다. 반면에, 지방족 카르복실산의 탄소원자수가 9이상이면, 조성물내 용해도는 현저히 감소된다.For example, the C 7 -C 9 aliphatic carboxylic acid can be enanthic acid, octylic acid, or caprylic acid. When the number of carbon atoms in the aliphatic carboxylic acid is 7 or less, high volatility is shown. For this reason, there is a difficulty in handling the compound. On the other hand, if the number of carbon atoms of the aliphatic carboxylic acid is 9 or more, the solubility in the composition is significantly reduced.
조성물내 지방족 카르복실산 화합물 농도는 0.01 내지 5.0중량% 범위이고, 바람직하게는 0.5 내지 5.0중량%이다. 지방족 카르복실산 화합물의 농도가 0.01중량% 이하이면, 조성물은 금속 부식을 충분히 방지하지 못한다. 반면에, 지방족 카르복신산 화합물 농도가 5.0중량% 이상이면 화합물은 조성물내에서 충분히 용해되지 않을 수 있다.The aliphatic carboxylic acid compound concentration in the composition is in the range of 0.01 to 5.0% by weight, preferably 0.5 to 5.0% by weight. If the concentration of the aliphatic carboxylic acid compound is 0.01% by weight or less, the composition does not sufficiently prevent metal corrosion. On the other hand, when the concentration of the aliphatic carboxylic acid compound is 5.0 wt% or more, the compound may not be sufficiently dissolved in the composition.
예컨대, 트리아졸 화합물은 벤조트리아졸(benzotriazole) 또는 토일트리아졸 (toyltriazole)이다. 조성물내 트리아졸 화합물 농도는 0.01 내지 1.0중량% 범위이고, 바람직하게는 0.01 내지 0.5중량%범위이다. 트리아졸 화합물 농도가 0.01중량% 이하이면, 조성물은 구리 함유 금속의 부식을 충분히 방지하지 못한다. 반면에, 트리아졸 화합물의 농도가 1.0중량% 이상이면, 화합물은 조성물내 충분히 용해되지 않을 수 있다.For example, the triazole compound is benzotriazole or toyltriazole. The triazole compound concentration in the composition is in the range of 0.01 to 1.0% by weight, preferably in the range of 0.01 to 0.5% by weight. If the triazole compound concentration is 0.01% by weight or less, the composition does not sufficiently prevent corrosion of the copper-containing metal. On the other hand, when the concentration of the triazole compound is 1.0% by weight or more, the compound may not be sufficiently dissolved in the composition.
바람직하게는, 조성물은 항부식제의 용해도를 개선시킬 수 있는 용매를 추가로 포함한다. 상기 용매는 바람직하게는 에틸렌글리콜 또는 프로필렌글리콜이다. 상기 용매들은 획득이 용이하고 조성물 냉각특성을 파괴하지 않는다. 상기 용매 농도는 바람직하게는 1 내지 10중량% 범위이고, 보다 바람직하게는 1 내지 5중량%범위이다. 용매 농도가 1중량% 이하이면, 항부식제의 용해도는 충분히 개선되지 않는다. 반면에, 용매 농도가 10중량% 이상이면, 조성물의 점도는 증가한다.Preferably, the composition further comprises a solvent that can improve the solubility of the anticorrosive. The solvent is preferably ethylene glycol or propylene glycol. The solvents are easy to obtain and do not destroy the composition cooling properties. The solvent concentration is preferably in the range of 1 to 10% by weight, more preferably in the range of 1 to 5% by weight. If the solvent concentration is 1% by weight or less, the solubility of the anticorrosive is not sufficiently improved. On the other hand, if the solvent concentration is at least 10% by weight, the viscosity of the composition increases.
제1 구현예와 같이, 제2 구현예의 조성물은 트리아졸 화합물; 붕산, 붕산염, 또는 이들의 조합물; 및 몰리브덴산, 몰리브덴산염, 또는 이들의 조합물로 구성된 군으로부터 선택된 하나 이상의 항부식제를 추가로 포함할 수 있다. 상기 설명한 바와 같이, 조성물은 착색제, 소포제, 산미제(bitter agent), 또는 이들의 조합물을 포함할 수 있다.As in the first embodiment, the composition of the second embodiment comprises a triazole compound; Boric acid, borate, or a combination thereof; And one or more anticorrosive agents selected from the group consisting of molybdate, molybdate, or combinations thereof. As described above, the composition may comprise colorants, antifoams, bitter agents, or combinations thereof.
제1 구현예에 설명한 바와 같이, 조성물에 대한 항부식효과를 개선시키기 위하여, 조성물은 바람직하게는 pH 7-11로 조정된다. 나아가, 조성물은 바람직하게는 알칼리금속염을 포함한다. 바람직하게는 조성물내 포름산염, 카르복실화합물, 트리아졸 화합물, 붕산염, 및 몰리브덴산염 중의 하나가 알칼리금속염이다. 상기 알칼리금속염은 불용성 물질의 생성을 억제한다.As described in the first embodiment, in order to improve the anticorrosive effect on the composition, the composition is preferably adjusted to pH 7-11. Furthermore, the composition preferably comprises an alkali metal salt. Preferably one of the formate, carboxyl compound, triazole compound, borate salt, and molybdate salt in the composition is an alkali metal salt. The alkali metal salt inhibits the production of insoluble matters.
제2 구현예 조성물은 포름산염과 물을 포함하는 주요성분, 및 지방족 카르복실산 화합물 및 트리아졸 화합물을 포함하는 항부식제를 포함한다. 지방족 카르복실산 화합물은 1)C10-C22지방족 2가 카르복실산(aliphatic dicarboxylic acid), 2)C7-C9지방족 1가 카르복실산(aliphatic monocarboxylic acid), 3) 상기 1) 또는 2)의 무수화물(anhydride), 및 4) 상기 1) 또는 2)의 알칼리금속염으로 구성된 군으로부터 선택된다.The second embodiment composition comprises a main component comprising formate and water, and an anticorrosive agent comprising an aliphatic carboxylic acid compound and a triazole compound. Aliphatic carboxylic acid compounds include 1) C 10 -C 22 aliphatic dicarboxylic acid, 2) C 7 -C 9 aliphatic monocarboxylic acid, 3) 1) or Anhydride of 2), and 4) an alkali metal salt of 1) or 2) above.
제2 구현예의 조성물은 포름산염을 포함한다. 제1 구현예와 마찬가지로, 제2 구현예는 우수한 냉각특성을 나타낸다.The composition of the second embodiment comprises formate. Like the first embodiment, the second embodiment exhibits excellent cooling characteristics.
지방족 카르복실산 화합물 및 트리아졸 화합물은 철, 구리, 및 알류미늄 함유 금속에 대해 높은 항부식효과를 나타낸다. 상기 화합물들의 사용은 금속에 대한 항부식효과를 개선시킨다. 따라서, 엔진냉각시스템은 장기간 거의 아무런 문제없이 작동가능하다. 이것은 시스템의 유지비를 감소시킨다.Aliphatic carboxylic acid compounds and triazole compounds exhibit high anticorrosive effects on iron, copper, and aluminum containing metals. The use of these compounds improves the anticorrosive effect on the metal. Therefore, the engine cooling system can be operated almost without any problem for a long time. This reduces the maintenance cost of the system.
2가 카르복실산 및 무수화물 및 이들의 알칼리금속염은 냉각시스템이 높은 온도, 빠른 유속으로 작동할 때 특히 알류미늄 및 알류미늄 합금에 대해 높은 항부식효과를 타나낸다. 그러므로, 금속표면의 색깔이 흑색으로 변하는 것을 방지할 수 있다. 지방족 카르복실산 및 무수화물 및 이들의 알칼리금속염은 상기 설명한 알류미늄 함유 금속에 대해 높은 항부식효과를 나타내며, 값이 싸다. 상기 화합물들은 액체이며 다루기 쉽다.Divalent carboxylic acids and anhydrides and their alkali metal salts exhibit high anticorrosive effects, particularly for aluminum and aluminum alloys, when the cooling system is operated at high temperatures, high flow rates. Therefore, it is possible to prevent the color of the metal surface from turning black.
