상기 목초액은 살충제 조성물 전체 대비 최적으로 7.5 중량부가 첨가되며, 본 발명에 따른 식물추출물이 함유된 살충제 조성물의 살충효과를 더욱 향상시키는 역할을 하는데, 이러한 목초액은 나무로 숯을 만드는 과정에서 나오는 연기를 액화시켜 채취한 뒤, 6개월 이상 숙성시켜 독성과 유해물질을 제거하여 제조된다.The wood vinegar is 7.5 parts by weight is optimally added to the total pesticide composition, and serves to further improve the insecticidal effect of the pesticide composition containing the plant extract according to the present invention, such wood vinegar is smoke from the process of making charcoal wood It is collected by liquefaction and aged for more than 6 months to remove toxic and harmful substances.
또한, 목초액은 숯가마 굴뚝의 온도가 85 내지 120℃가 되었을 때 채취한 연기를 채취하여 제조된 것이 가장 우수한 살충효과를 나타내며, 연기에서 채취한 액을 6개월 이상 숙성 및 분리시키는 과정을 통해 제조된 것을 사용하는 것이 바람직하고, 수용성과 유용성으로 분리되는데, 수용성의 액체를 채취하여 사용한다.In addition, wood vinegar is produced by collecting the smoke collected when the temperature of the charcoal chimney 85 to 120 ℃ exhibits the best insecticidal effect, produced by the process of aging and separating the liquid collected from the smoke for more than six months It is preferable to use one, and it is separated into water solubility and oil solubility, and a water-soluble liquid is collected and used.
또한, 목초액은 pH가 3 전후의 산성을 띠며, 성분은 80 내지 90%가 물이며, 아세트산 3%이다. 그 외에 폼산, 지방산 및 메탄올 등과 200여 종에 이르는 소량의 미네랄을 포함한다.In addition, wood vinegar has an acidic pH of about 3, the component is 80 to 90% water, acetic acid 3%. In addition, formic acid, fatty acids and methanol and the like contains a small amount of more than 200 kinds of minerals.
전술한 목초액의 함량이 7.5 중량부 미만으로 함유되면, 본 발명에 따른 식물추출물이 함유된 살충제 조성물의 살충효과가 저하되며, 목초액의 함량이 7.5 중량부 초과이면, 살충 효과는 더 이상 향상되지 않고, 제조비용을 증가시키게 된다.When the content of the above-mentioned wood vinegar is contained less than 7.5 parts by weight, the insecticidal effect of the pesticide composition containing the plant extract according to the present invention is lowered, and if the content of wood vinegar is more than 7.5 parts by weight, the insecticidal effect is no longer improved This increases the manufacturing cost.
상기 계면활성제는 살충제 조성물 전체 대비 최적으로 1.5 중량부가 첨가되며, 전술한 식물추출물 및 목초액이 고르게 혼합될 수 있도록 하는 역할을 할 뿐만 아니라, 본 발명에 따른 식물추출물이 함유된 살충제 조성물을 정제수 등에 희석하여 사용할 때, 본 발명에 따른 식물추출물이 함유된 살충제 조성물가 고르게 혼합될 수 있도록 하는 역할을 한다.The surfactant is optimally added 1.5 parts by weight relative to the total pesticide composition, and serves to allow the above-mentioned plant extract and wood vinegar to be evenly mixed, and dilute the insecticide composition containing the plant extract according to the present invention to purified water or the like. When used, the pesticide composition containing the plant extract according to the present invention serves to be evenly mixed.
상기 계면활성제의 함량이 1.5 중량부 미만으로 첨가되면, 식물추출물 및 목초액이 고르게 혼합되지 않아 상 분리가 발생하며, 본 발명에 따른 식물추출물이 함유된 살충제 조성물을 정제수에 희석할 때, 고르게 혼합되지 않아 균일한 성능을 나타내는 살충제 조성물을 제조할 수 없게 되며, 상기 계면활성제의 함량이 1.5 중량부를 초과하여 첨가되면, 혼합성은 더 이상 향상되지 않고, 식물추출물이나 목초액의 상대적인 함량이 줄어들어 살충제 조성물의 살충효과가 저하된다.When the content of the surfactant is added less than 1.5 parts by weight, the plant extract and wood vinegar are not evenly mixed to cause phase separation, and when the pesticide composition containing the plant extract according to the present invention is diluted in purified water, it is not evenly mixed. As a result, it is impossible to prepare a pesticide composition showing uniform performance, and when the content of the surfactant is added in excess of 1.5 parts by weight, the blendability is no longer improved, and the relative content of the plant extract or wood vinegar is reduced, so that the insecticide composition of the pesticide composition is reduced. The effect is lowered.
이때, 상기 계면활성제는 폴리옥시에틸렌 소르비탄 모노올리트(Polyoxyethylene sorbitan monooleate)로 이루어지는것이 바람직하다.At this time, the surfactant is preferably made of polyoxyethylene sorbitan monooleate (Polyoxyethylene sorbitan monooleate).
또한, 본 발명에 따른 식물추출물이 함유된 살충제 조성물의 제조방법은 식물을 유기용매에 투입하여 식물추출물을 추출하는 추출단계(S101), 상기 추출단계(S101)를 통해 추출된 식물추출물을 감압농축기로 농축하는 농축단계(S103), 상기 농축단계(S103)를 거친 식물추출물에 목초액 및 계면활성제를 투입하고 교반하는 교반단계(S105)로 이루어진다.In addition, the method for producing a pesticide composition containing a plant extract according to the present invention is an extracting step (S101) for extracting the plant extract by inputting the plant in an organic solvent, the concentrated plant extract extracted through the extraction step (S101) Concentration step (S103) to be concentrated to, the mixing step consisting of a stirring step (S105) to add the wood vinegar and surfactant to the plant extracts through the concentration step (S103) and stirred.
상기 추출단계(S101)는 식물을 유기용매에 투입하여 식물추출물을 추출하는 단계로, 식물 100 중량부를 유기용매 500 내지 1500 중량부에 투입하고 햇빛을 차단한 상태에서 추출하여 이루어지는데, 더욱 상세하게는 회화나무, 멀구슬나무 및 양명아주로 이루어진 그룹으로부터 선택된 하나 이상의 식물 100 중량부를 순도가 95%인 에탄올 500 내지 1500 중량부에 투입하고, 햇빛을 차단한 상태에서 40 내지 50시간 동안 이루어진다.The extraction step (S101) is a step of extracting the plant extract by putting the plant in an organic solvent, 100 parts by weight of the organic solvent is added to 500 to 1500 parts by weight and is made by extracting in a state of blocking the sunlight, in more detail 100 parts by weight of at least one plant selected from the group consisting of a painting tree, mulberry and Yangmingju is added to 500 to 1500 parts by weight of ethanol having a purity of 95%, it is made for 40 to 50 hours in the state of blocking sunlight.
상기 농축단계(S103)는 추출단계(S101)를 통해 추출된 식물추출물을 감압농축기로 농축하는 단계로, 상기 추출단계(S101)를 통해 추출된 식물추출물을 감압농축기로 30 내지 43℃의 온도에서 농축하여 상기 식물추출물에 함유된 마트린의 함량을 0.5 내지 1%로 조절하는 단계다.The concentration step (S103) is a step of concentrating the plant extract extracted through the extraction step (S101) with a reduced pressure concentrator, the plant extract extracted through the extraction step (S101) at a temperature of 30 to 43 ℃ with a reduced pressure concentrator Concentrating is the step of adjusting the content of matrin contained in the plant extract to 0.5 to 1%.
상기 교반단계(S105)는 상기 농축단계(S103)를 거친 식물추출물에 목초액 및 계면활성제를 투입하고 교반하는 단계로, 식물추출물 91 중량부에 목초액 7.5 중량부 및 계면활성제 1.5 중량부를 투입하여 이루어진다.The stirring step (S105) is a step of adding the wood vinegar and surfactant to the plant extracts subjected to the concentration step (S103) and stirring, it is made by adding 7.5 parts by weight of wood vinegar and 1.5 parts by weight of surfactant to 91 parts by weight of the plant extract.
이때, 상기 식물추출물, 목초액 및 계면활성제의 역할 및 함량에 따른 효과의 변화는 상기 식물추출물이 함유된 살충제 조성물에 나타낸 바와 동일함으로, 이에 대한 설명은 생략하기로 한다.At this time, the change of the effect according to the role and content of the plant extract, wood vinegar and surfactant is the same as shown in the pesticide composition containing the plant extract, a description thereof will be omitted.
또한, 상기 교반단계(S105) 이후에는 상기 교반단계를 통해 제조된 혼합물 전체에 대비 최적으로 0.2%의 전착제 및 0.001%의 거품제거제를 추가하는 첨가제투입단계(S107)가 더 진행될 수 있다.In addition, after the stirring step (S105), an additive injection step (S107) of adding 0.2% of an electrodepositing agent and 0.001% of an antifoaming agent may be further performed in comparison to the entire mixture prepared through the stirring step.
상기 전착제는 살충제의 물리적 흡착성을 향상시키는 보조제로서 작물 또는 병해충의 표면에 균일하게 퍼지고, 잘 붙어 풍우에도 유실되지 않도록 하는 성질을 갖게 하며, 침투성을 증대시켜 살충제를 병해충의 조직내에 침투시키는 기능을 하게 되며, 혼합 비율이 0.2% 미만이면 최종 살충력의 흡착성 및 침투성이 저하되며, 0.2% 초과이면 살충력의 저하 및 영향이 있게 되며, 추가 제조비용이 증가하게 된다.The electrodeposition agent is an adjuvant that improves the physical adsorption of the pesticide, and spreads evenly on the surface of the crop or pest, and adheres well to prevent loss of weather, and increases the permeability to infiltrate the pesticide into the pest tissue. If the mixing ratio is less than 0.2%, the adsorptivity and permeability of the final insecticide is lowered, and if it exceeds 0.2%, there is a decrease and impact of the insecticide, and the additional manufacturing cost is increased.
또한, 상기 거품제거제는 보관 및 사용시의 거품을 최대한 저하시키고 혼합액을 안정시키기 위한 보조제로서, 최소한의 기능성 및 생산성면에서 최적으로는 0.001%의 혼합비율로 추가한다.In addition, the defoamer is an auxiliary agent for lowering the foam during storage and use as much as possible and stabilizing the mixed solution, and is optimally added at a mixing ratio of 0.001% in terms of minimum functionality and productivity.
또한, 상기 전착제 및 거품제거제 대신 또는 상기 첨가제투입단계(107) 이후에 제조 완료된 살충제 조성물 100 중량부 대비 편백나무 정유 5 내지 15 중량부를 혼합하는 추가 첨가제투입단계가 더 진행될 수도 있다.In addition, an additional additive injection step of mixing 5 to 15 parts by weight of nectar essential oil with respect to 100 parts by weight of the prepared insecticide composition instead of the electrodeposition agent and the antifoaming agent or after the additive injection step 107 may be further performed.
상기 편백나무 정유는 피톤치드를 다량 방출하여, 본 발명에 따른 식물추출물이 함유된 살충제 조성물의 살충효과를 더욱 향상시키며, 상기 편백나무 정유의 함량이 5 중량부 미만이면, 편백나무 정유로 인한 살충효과가 미미하며, 편백나무 정유의 함량이 15 중량부를 초과하게 되면 살충효과의 향상은 미미하며, 제조비용이 증가된다.The cypress essential oil releases a large amount of phytoncide, further improves the insecticidal effect of the insecticide composition containing the plant extract according to the present invention, and if the content of the cypress essential oil is less than 5 parts by weight, the insecticidal effect due to the cypress essential oil If the content of the cypress essential oil exceeds 15 parts by weight, the improvement of the insecticidal effect is insignificant, and the manufacturing cost is increased.
이때, 전술한 편백나무 정유는 편백나무를 채취하여 가지와 잎을 분리하고 물로 세척한 후에, 세척된 가지와 잎을 증류 탱크에 넣고 가열수단을 이용하여 고온의 스팀을 공급하고, 증류 탱크 내부에 공급된 고온의 스팀에 의해 추출된 정유 성분이 함유된 수증기를 냉각기에 공급하여 응축된 정유 성분이 함유된 수증기를 정유 탱크에 공급하여 정유를 추출하는 과정을 통해 제조된다.At this time, the above-mentioned cypress essential oil is separated from the branches and leaves and washed with water after collecting the cypress, put the washed branches and leaves in a distillation tank and supply the high-temperature steam using a heating means, inside the distillation tank It is manufactured through a process of extracting essential oil by supplying steam containing the essential oil component extracted by the supplied high temperature steam to the cooler and supplying the steam containing the condensed essential oil component to the refinery tank.
