Description
본 발명은 폐기물을 이용한 수지 미장 모르타르 조성물에 관한 것으로, 더욱 상세하게는 종래 모르타르 조성물에 사용되는 모래를 규산암 광산에서 규사 정제 공정 중 발생하는 부산물인 미립 분말(이하 '슬라임'이라 한다)로 대체하고 접착력을 향상시키는 수지, 보수성을 증가시키는 증점제, 작업성을 향상시키는 유동화제 등을 일정 비율로 배합하여 건축물 미장용 모르타르 조성물을 제조함으로써, 종래의 모르타르 조성물과 동등하게 우수한 물성뿐만 아니라 폐자재 재활용으로 인한 환경오염 방지와 원가절감의 효과를 가지는 수지 미장 모르타르 조성물에 관한 것이다.The present invention relates to a resin plaster mortar composition using waste, and more particularly, to replace the sand used in the conventional mortar composition with fine powder (hereinafter referred to as 'slime') which is a by-product generated during the silica sand refining process in a silicate mine. By mixing the resin to improve the adhesive force, the thickener to increase the water-retaining ability, the fluidizing agent to improve the workability, etc. in a proportion to prepare a mortar composition for building plastering, recycling of waste materials as well as excellent physical properties equivalent to the conventional mortar composition The present invention relates to a resin mortar mortar composition having an effect of preventing environmental pollution and reducing costs.
일반적으로 수지 미장 모르타르는 모래, 시멘트, 석회석, 수지 등을 일정비율로 배합하여 만들어지고 있다. 이러한 모르타르의 원료로 사용하고 있는 모래는 주로 강모래를 사용하고 있으나, 현재 강모래가 부족한 실정이어서 바다모래를 여러 번 세척하여 사용하고 있다. 그러나 바다모래는 철근 부식, 백화 현상등의 문제를 발생시키고 있으므로, 바다모래를 사용하기 위해서는 이러한 현상의 원인인 염분을 제거하기 위해 여러 번 세척한 후 건조하는 과정을 거쳐야 하는 문제가 있다.In general, resin mortar mortar is made by mixing sand, cement, limestone, resin and the like in a certain ratio. Sand used as a raw material of mortar mainly uses river sand, but the current situation is insufficient river sand is used to wash the sea sand several times. However, since the sea sand is causing problems such as rebar corrosion, whitening phenomenon, there is a problem that in order to use the sea sand has to go through the process of washing and drying several times to remove the salt that causes this phenomenon.
이러한 강모래의 부족 현상을 보완하기 위하여 폐주물사, 시멘트 폐슬러지 등의 폐기물을 사용한 모르타르의 개발이 이루어지고 있다. 주조공장에서 주형 후 폐기되는 폐주물사를 건축자재인 골재로 재사용하는 기술은 천연산의 모래보다 건조 비용이 적게 들고 공해물질인 폐주물사를 산업에 이용하므로서 공해 방지의 효과가 있고, 이 폐주물사를 폐기하는데 소요 경비가 절감되고, 제품의 품질을 균일하게 할 수 있다는 장점이 있다. 그러나 폐주물사를 이용한 모르타르는 산화 및 백화현상의 주원인인 철분 및 규산소다, 염화나트륨 등을 제거 및 소멸시켜 골재로 재생하는 복잡한 공정을 거쳐야 하는 문제점을 가지고 있다.In order to compensate for the shortage of steel sand, the development of mortar using wastes such as waste foundry sand and cement waste sludge has been made. The technology of reusing waste foundry sand that is discarded after casting in a casting plant as aggregate is less expensive to dry than sand of natural acid, and it is effective to prevent pollution by using waste foundry sand, which is a pollutant, for the industry. The cost is reduced and the quality of the product can be made uniform. However, mortar using waste foundry sand has a problem of undergoing a complex process of removing and extinguishing iron, sodium silicate, sodium chloride, etc., which are the main causes of oxidation and whitening, and recycling them into aggregate.
상기 폐기물을 이용한 모르타르의 예로는 대한민국 특허공개 제91-18325호에는 연탄재, 폐합성수지, 아스팔트 등을 혼합하여 제조한 모르타르를 개시하고 있고, 대한민국 특허공개 제94-4379호에는 폐석회, 시멘트, 실리케이트염, 안료, 계면활성제 등을 혼합하여 건축자재로 활용하고, 대한민국 특허공개 제96-29084에는 건축폐기물을 건축자재로 재사용하는 방법이 개시되어 있다.Examples of the mortar using waste include Korean Patent Publication No. 91-18325, which discloses mortar prepared by mixing briquette materials, waste synthetic resin, asphalt, etc., and Korean Patent Publication No. 94-4379 discloses waste lime, cement, and silicate. Salts, pigments, surfactants, etc. are mixed and used as building materials, and Korean Patent Publication No. 96-29084 discloses a method for reusing building wastes as building materials.
그러나, 종래의 폐기물을 건축자재로 이용하는 방법은 폐자재를 모래나 시멘트 등과 섞어 건축자재화하기 위하여 첨가물질을 과도하게 사용하거나 강알카리성인 폐주물사를 사용함으로써 처리공정을 복잡하게 하여 비용이 높고 실제 건축자재로 활용하려고 해도 기존의 건축자재와 물성의 차이가 크므로 시공상 채택되는 경우가 거의 없어 실용화되지 못하고 있는 실정이다.However, the conventional method of using waste as a building material is expensive and actual building material by complicating the processing process by using excessive additives or using strong alkaline waste casting sand to mix the waste material with sand or cement. Even if it is used as a material, the difference between the existing building materials and the physical properties is large, it is rarely adopted in construction, and it is not practically used.
이에, 본 발명의 발명자들은 상기한 문제점을 해결하기 위해 규산암 광산에서 규사 정제 공정 중 발생하는 부산물인 미립 분말인 슬라임으로 모래를 대체하고 접착력을 향상시키는 수지, 보수성을 증가시키는 증점제, 작업성을 향상시키는 유동화제 등을 일정 비율로 배합하여 본 발명을 완성하였다.Therefore, the inventors of the present invention to solve the above problems in the silicate mine by-products during the silica sand refining process, slime, which is a fine powder to replace the sand and improve the adhesive force, thickener, increase workability, workability The present invention was completed by blending a fluidizing agent and the like in a proportion.
따라서, 본 발명은 종래의 모르타르 조성물과 동등하게 우수한 물성뿐만 아니라 폐자재 재활용으로 인한 환경오염 방지와 원가절감의 효과를 가지는 수지 미장 모르타르 조성물을 제공하는데 그 목적이 있다.Therefore, an object of the present invention is to provide a resin mortar mortar composition having an effect of preventing environmental pollution and cost reduction due to waste material recycling as well as excellent physical properties equivalent to the conventional mortar composition.
본 발명은 폐기물을 이용한 시멘트 모르타르에 있어서, 슬라임 40 ∼ 60 중량부 및 포틀랜드 시멘트 60 ∼ 40 중량부와 상기 성분 100 중량부에 대하여 수지 1.0 ∼ 3.0 중량부, 증점제 0.2 ∼ 0.4 중량부, 유동화제 0.1 ∼ 0.2 중량부가 포함된 모르타르 조성물을 그 특징으로 한다.In the cement mortar using waste, 40 to 60 parts by weight of slime, 60 to 40 parts by weight of Portland cement and 100 parts by weight of the above components, 1.0 to 3.0 parts by weight of resin, 0.2 to 0.4 parts by weight of thickener, and fluidizing agent 0.1 It is characterized by the mortar composition containing-0.2 weight part.
이와같은 본 발명을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.
규산암 광산에서 부산물로 발생하는 슬라임은 실리카(SiO2) 90±5%, 산화알루미나(Al2O3) 4.5±0.5%, 산화철(Fe2O3) 2.0±0.2%의 조성으로 이루어져 있으며, 함수율이 약 25%이며 평균 입도가 40 ∼ 50 ㎛인 미립 분말이다. 이러한 슬라임은 년간 10여만톤이 발생되고 있으나 실리카의 순도가 낮으므로 유리 및 고순도의 실리카를 요구하는 다른 용도에는 적합하지 않아 폐기물로 간주되어 매립되어왔다.The slime generated as a by-product from the silicate mine is composed of 90 ± 5% silica (SiO 2 ), 4.5 ± 0.5% alumina oxide (Al 2 O 3 ), and 2.0 ± 0.2% iron oxide (Fe 2 O 3 ). A fine powder having a water content of about 25% and an average particle size of 40 to 50 µm. These slime are generated 100,000 tons per year, but because of the low purity of silica is not suitable for glass and other applications that require high purity silica has been considered as a waste landfill.
본 발명은 이러한 슬라임을 수지 미장 모르타르에 골재인 모래를 대체하여 사용하고자 한다.The present invention intends to use this slime in place of the aggregate aggregate in the resin plastering mortar.
일반적으로, 수지 미장 모르타르란 드라이 모르타르의 일종으로서 물만 부어서 직접 사용할 수 있는 모르타르이며, 혼화제로서 수지가 첨가되어 모르타르의 접착력을 향상시킨다. 수지 미장 모르타르는 접착력이 우수하기 때문에 기존에 후박 미장하던 것을 박도 미장을 할 수 있으므로 건물 자체의 중량이 감소되고 공유면적 증가의 장점이 있다.In general, resin plaster mortar is a kind of dry mortar, which can be used directly by pouring only water, and resin is added as a admixture to improve the adhesion of mortar. Resin plastering mortar has excellent adhesive strength, so it is possible to plaster plastering conventional thick plastering, which reduces the weight of the building itself and increases the shared area.
본 발명에 따른 수지 미장 모르타르의 조성성분에 따라 더욱 상세히 설명하면 다음과 같다.According to the composition of the resin plaster mortar according to the present invention in more detail as follows.
먼저, 본 발명에서 골재인 모래를 대체하는 성분인 슬라임은 40 ∼ 60 중량부 함유하는 것이 바람직하며, 만일 그 함유량이 40 중량부 미만이면 압축강도는 향상되나 시멘트 사용량이 증가하여 비경제적이며 작업성이 곤란하고, 60 중량부를 초과하면 강도가 저하되는 문제가 있다. 규산암 광산에서 부산물로 발생하는 슬라임은 젖은 상태로 존재하여 있기 때문에 슬라임을 수지 미장 모르타르의 골재로 사용하기 위해서는 수분 제거를 위해 건조시키고, 덩어리를 분말화시킨 후 사용할 수 있다.First, in the present invention, the slime, which is a component that replaces aggregate sand, is preferably contained in an amount of 40 to 60 parts by weight. If the content is less than 40 parts by weight, the compressive strength is improved, but the amount of cement is increased, which is uneconomical and workable. This is difficult and there exists a problem that intensity | strength will fall when it exceeds 60 weight part. Since the slime generated as a by-product from the silicate mine is wet, it can be used after drying to remove moisture and pulverizing the mass to use the slime as aggregate of resin plastering mortar.
그리고, 모르타르의 주성분인 시멘트는 포틀랜드 시멘트를 40 ∼ 60 중량부 함유하는 것이 바람직하며, 만일 그 함유량이 40 중량부 미만이면 모르타르의 강도가 저하되는 문제가 있고, 60 중량부를 초과하면 비경제적인 문제가 있다.In addition, the cement, which is the main component of mortar, preferably contains 40 to 60 parts by weight of portland cement, and if the content is less than 40 parts by weight, the strength of the mortar may be lowered. have.
수지 미장 모르타르의 접착력을 향상시키기 위해 사용하는 수지는 상기 슬라임과 포틀랜드 시멘트 100 중량부에 대하여 1.0 ∼ 3.0 중량부 함유하는 것이 바람직하며, 만일 그 함유량이 1.0 중량부 미만이면 접착력이 부족한 문제가 있고, 3.0 중량부를 초과하면 비경제적인 문제가 있다. 상기 수지로는 에틸렌비닐아세테이트 수지(Ethylene vinyl acetate copolymer), 스티렌-부타디엔 러버(SBR), 아크릴 수지(Acryl Resin) 등을 사용할 수 있다.The resin used to improve the adhesive strength of the resin plaster mortar is preferably contained 1.0 to 3.0 parts by weight based on 100 parts by weight of the slime and Portland cement, if the content is less than 1.0 parts by weight, there is a problem of insufficient adhesive strength, If it exceeds 3.0 parts by weight, there is an uneconomic problem. Ethylene vinyl acetate copolymer, styrene-butadiene rubber (SBR), acrylic resin (Acryl Resin), etc. may be used as the resin.
본 발명에 따른 수지 미장 모르타르는 드라이 모르타르로 미장 후 빨리 건조되는 현상으로 인한 균열 및 강도저하의 문제점을 보완하기 위하여 보수성을 나타내는 증점제를 상기 슬라임과 포틀랜드 시멘트 100 중량부에 대하여 0.2 ∼ 0.4 중량부 함유하는 것이 바람직하며, 만일 상기 범위를 벗어나면 건조가 빨리 되어 균열 및 강도저하가 발생하는 문제가 있다. 상기 증점제로는 셀룰로오스 계통을 사용할 수 있으며, 예컨대 메틸셀룰로오스, 에틸셀룰로오스, 셀룰로오스에테르 등을 사용할 수 있다.The resin plaster mortar according to the present invention contains 0.2 to 0.4 parts by weight of the thickener showing water retention rate based on 100 parts by weight of the slime and Portland cement in order to compensate for the problems of cracking and strength deterioration caused by the phenomenon of drying quickly after plastering with dry mortar. If it is out of the above range it is preferable to dry quickly, there is a problem that cracks and strength decreases. As the thickener, a cellulose system may be used. For example, methyl cellulose, ethyl cellulose, cellulose ether, or the like may be used.
본 발명에 사용하는 슬라임은 미립 분말이기 때문에 비표면적이 커서 수지 미장 모르타르를 사용시 혼수량이 많아지게 된다. 혼수량이 많아지게 되면 작업성은 좋아지나 강도저하 현상이 발생하게 되므로, 이러한 점을 보완하기 위하여 유동화제를 상기 슬라임과 포틀랜드 시메트 100 중량부에 대하여 0.1 ∼ 0.2 중량부 함유하는 것이 바람직하며, 만일 그 함유량이 0.1 중량부 미만이면 흐름성이 적어 미장에 어려움이 있고, 0.2 중량부를 초과하면 흘러내려 작업성이 불량한 문제가 있다. 상기 유동화제로는 멜라닌설폰산염, 나프탈렌설폰산염, 리그닌설폰산염 등을 사용할 수 있다.Since the slime used in the present invention is a fine powder, the specific surface area is large, and the amount of coma increases when the resin plaster mortar is used. If the amount of coma increases, the workability is improved but the strength decreases. Therefore, in order to compensate for this, it is preferable to contain 0.1 to 0.2 parts by weight of the fluidizing agent based on 100 parts by weight of the slime and Portland Simet. If the content is less than 0.1 part by weight, the flowability is small and there is difficulty in plastering, and if the content is more than 0.2 part by weight, there is a problem of poor flowability. As the fluidizing agent, melanin sulfonate, naphthalene sulfonate, lignin sulfonate and the like can be used.
이와같은 본 발명에 따른 모르타르 조성물은 수지 미장 모르타르로 내력벽이나 계단벽에 사용할 수 있으며, 종래의 모르타르 조성물과 동등하게 우수한 물성뿐만 아니라 폐자재 재활용으로 인한 환경오염 방지와 원가절감의 효과를 가진다.Such a mortar composition according to the present invention can be used in the bearing wall or stair wall as a resin mortar mortar, and has the effect of preventing environmental pollution and cost reduction due to waste material recycling as well as excellent physical properties similar to the conventional mortar composition.
