Same as

본 발명은 도 1에 도시된 바와 같이, 옻액과 에탄올을 혼합하는 단계(S10), 상기 혼합물을 원심분리하는 단계(S20), 원심분리를 통하여 추출된 우루시올층을 가열하는 단계(S30), 우루시올과 이소시아네이트(ISOCYANATE)의 혼합단계(S41, 50), 우루시올과 이소시아네이트(ISOCYANATE)의 혼합물의 경화단계(S42, 51), 제조된 우루시올이 함유된 고체혼합물(S60)로 이루어진다.1, the step of mixing the lacquer and ethanol (S10), the step of centrifuging the mixture (S20), the step of heating the urushiol layer extracted through centrifugation (S30), urushiol Mixing step (S41, 50) of the isocyanate (ISOCYANATE), curing step (S42, 51) of the mixture of urushiol and isocyanate (ISOCYANATE), the solid mixture containing the prepared urushiol (S60).

또한, 본 발명은 도 2에 도시된 바와 같이, 우루시올이 함유된 고체혼합물(S60)을 분쇄하는 단계(S70), 200mesh로 분급하는 단계(S80)로 제조되는 우루시올이 함유된 고체혼합물(S90)의 분말로 이루어진다.In addition, the present invention, as shown in Figure 2, the solid mixture containing the urushiol (S60) is pulverized (S70), the urushiol-containing solid mixture (S90) prepared by the step of classifying to 200mesh (S90) Made of powder.

본 발명에 사용되는 생 옻 또는 옻액은 한국산, 중국산 또는 일본산 어느 것 이어도 상관없으며, 상기 옻액과 에탄올을 혼합하여 원심분리를 하게 된다. 옻액과 에탄올을 혼합하는 이유는 옻액 자체는 점도가 너무 높아 원심분리가 되지 않기 때문에 점도를 낮추고 우루시올을 에탄올로 용해시켜 우루시올 외 고무질과 질소화합물과의 분리를 용이하게 하기 위함이다. 이때, 에탄올 대신 아세톤 또는 크실렌 등 유기용제는 사용이 가능하나, 에탄올은 다른 유기용제 보다 환경유해성이 낮고 끓는점도 낮아 환경적, 경제적으로 유리하다. 하지만, 옻액과 에탄올의 혼합되는 중량비율이 1 : 0.8 미만이면 에탄올이 우루시올을 충분하게 용해시키지 못하여 원심분리가 완전하게 이루어지지 않는다는 문제점이 있으며, 옻액과 에탄올의 혼합 중량비율이 1 : 1.2를 초과하면 원심분리는 잘 되나 이후 감압증류에 의해 에탄올과 물을 증발시킬 때 증발에 필요한 시간 및 비용이 증가되는 문제점이 있어 옻액과 에탄올의 혼합 중량비율은 1 : 0.8 ~ 1.2로 함이 바람직하다. 이후, 10,000rpm 이상으로 원심분리하면 고무질, 질소화합물이 침적된 고형분은 하층에 가라앉고, 상층에 있는 에탄올에 용해된 우루시올을 분리하는 것이 가능해진다. 이때, 원심분리한 우루시올뿐만 아니라, 생옻도 가능하나 우루시올의 함량을 높이기 위하여 원심분리한 우루시올을 반응에 사용한다. 원심분리에 의해 분리된 우루시올과 에탄올의 혼합액에 대해 40℃~100℃로 감압 가열 또는 진공 가열하여 에탄올과 수분을 증발 제거시켜 액상의 우루시올만을 수득한다. 여기서 수득된 우루시올과 이소시아네이트(ISOCYANATE)를 혼합하고 교반하면 반응이 일어나 고체로 변한다. The raw lacquer or lacquer liquid used in the present invention may be either Korean, Chinese, or Japanese, and centrifuged by mixing the lacquer and ethanol. The reason why the lacquer and ethanol are mixed is to reduce the viscosity and dissolve urushiol with ethanol to facilitate separation of rubber and nitrogen compounds from urushiol because the lacquer itself is too high in viscosity to prevent centrifugation. At this time, an organic solvent such as acetone or xylene may be used instead of ethanol, but ethanol is environmentally and economically advantageous due to lower environmental hazards and lower boiling point than other organic solvents. However, if the weight ratio of the lacquer and ethanol is less than 1: 0.8, there is a problem in that the ethanol does not sufficiently dissolve urushiol and thus the centrifugation is not completely performed, and the mixed weight ratio of the lacquer and ethanol is greater than 1: 1.2. If the centrifugation is good, but after the evaporation of ethanol and water by distillation under reduced pressure, there is a problem that the time and cost required for evaporation increases, so the mixing weight ratio of lacquer and ethanol is preferably 1: 0.8 ~ 1.2. Subsequently, centrifugation at 10,000 rpm or more causes the solids in which rubbery and nitrogen compounds are deposited to sink in the lower layer, and it is possible to separate urushiol dissolved in ethanol in the upper layer. At this time, not only the centrifuged urushiol, but also raw lacquer can be used, but the centrifuged urushiol is used in the reaction to increase the content of the urushiol. The mixture of urushiol and ethanol separated by centrifugation was heated under reduced pressure or vacuum at 40 ° C. to 100 ° C. to evaporate and remove ethanol and water to obtain only liquid urushiol. When urushiol and isocyanate (ISOCYANATE) obtained here are mixed and stirred, a reaction takes place and turns into a solid.

상술한 바와같이 액상의 우루시올을 고체로 변환시키기 위하여 사용되어지는 이소시아네이트(ISOCYANATE)의 종류로는 TDI TRIMER, MDI, TDI, 등이 있으며, 이 소시아네이트(ISOCYANATE)기 (-N=C=O)가 있는 어느 것도 사용가능하다. As described above, the type of isocyanate (ISOCYANATE) used to convert the liquid urushiol into a solid includes TDI TRIMER, MDI, TDI, and the like, and isocyanate group (-N = C = O) Anything may be used.

이소시아네이트(ISOCYANATE)를 TDI TRIMER로 사용할 시에는 우루시올과 이소시아네이트(ISOCYANATE), 즉 TDI TRIMER의 혼합단계(S41, 50) 이전에 혼합 될 TDI TRIMER가 고형이므로 상기 우루시올과의 혼합이 용이하도록 시너(thinner)와 중량비율 약 1 : 1로 혼합하여 용융상태(S40)로 만든 후 상기 TDI TRIMER의 용융액과 우루시올을 혼합(S41)한다. When using isocyanate (ISOCYANATE) as TDI trimmer, since TDI trimmer to be mixed before the mixing step (S41, 50) of urushiol and isocyanate (ISOCYANATE), that is, TDI trimmer is solid, thinner to facilitate mixing with the urushiol After mixing in a weight ratio of about 1: 1 to a molten state (S40), the melt and urushiol of the TDI trimer are mixed (S41).

이때, 우루시올과 TDI TRIMER의 혼합비율은 1 : 0.8~1.2 중량비율이 적합하며 가장 이상적인 중량비율은 1 : 1이다. 우루시올과 혼합되는 TDI TRIMER의 중량비율이 0.8보다 작을 경우는 상기 반응이후의 혼합물은 우루시올이 충분히 반응되지 않고 남게 되어 고형이 아닌 용융상태가 되며, 1.2보다 클 경우는 TDI TRIMER가 과잉되어 옻의 효능이 떨어지게 된다. At this time, the mixing ratio of urushiol and TDI trimer is suitably 1: 0.8 to 1.2 weight ratio, the most ideal weight ratio is 1: 1. If the weight ratio of TDI TRIMER mixed with urushiol is less than 0.8, the mixture after the reaction will be left in a molten state without being sufficiently reacted with urushiol, and if it is larger than 1.2, the TDI TRIMER will be excessive and the efficacy of lacquer Will fall.

한편, 이소시아네이트(ISOCYANATE)를 MDI로 사용할 시에는 MDI가 액상이므로 우루시올과 혼합이 용이하나, 우루시올과 MDI는 1 : 0.5~0.9의 중량비율이 적합하며 가장 이상적인 중량비율은 1 : 0.75이다. MDI의 중량비율이 0.5보다 작을 경우는 우루시올과 MDI의 혼합물이 용융상태가 되어 우루시올이 남게되고, 0.9보다 클 경우는 MDI가 과잉되어 옻의 효능이 떨어지게 된다. On the other hand, when using isocyanate (ISOCYANATE) as MDI, MDI is a liquid, so it is easy to mix with urushiol, but the weight ratio of urushiol and MDI is 1: 0.5 to 0.9, and the ideal weight ratio is 1: 0.75. If the weight ratio of MDI is less than 0.5, the mixture of urushiol and MDI becomes molten to leave urushiol, and if it is greater than 0.9, MDI becomes excessive and the effectiveness of lacquer is reduced.

여기서, MDI(메틸렌 디페닐 디이소시안산염)는 dicyclie 단냥체 MDI와 PLOYCYCLIE 폴리이소시아나이트(polymeric MDI)의 혼합으로 생성되며, 백색 내지는 미황색을 가지는 고체로 방향족 탄화수소, 염소화 방향족 탄화수소, 니트로벤젠, 아세톤, 에테르, 산화에틸, 디옥산 등에 녹으며, 상온에서 부식성은 비교적 적은 편이고, 아닐린에 포르말린을 반응시켜 산성축합을 한 후 포스겐과 반응시켜 제조한다.Here, MDI (methylene diphenyl diisocyanate) is a mixture of dicyclie monomer MDI and PLOYCYCLIE polyisocyanate (polymeric MDI), which is a white to pale yellow solid, aromatic hydrocarbon, chlorinated aromatic hydrocarbon, nitrobenzene, acetone , Soluble in ether, ethyl oxide, dioxane, etc., relatively low corrosiveness at room temperature, and is prepared by reacting aniline with formalin and acid condensation followed by phosgene.

또한, TDI(톨루엔 디이소시안산염)는 실온에서 무색, 저점성체이고 고형이며 주로 유용한 다공질체 뿐만 아니라 고체 탄성체를 생산하는데 사용된다. 그러나 TDI(Toluene D-isocyanate)는 TDA에 포스겐가스(phosgene)를 합성하여 생성되며, 폴리우레탄의 원료로 건축단열재 의자 자동차시트 고무접착제 섬유처리제 인조가죽 페인트 등을 만드는데 쓰인다. 상기 포스겐가스는 1, 2차 대전 당시 화학무기로 사용되어 120만명의 목숨을 앗사간 독사스로 폐부종, 폐암 등을 유발하며 소량만 흡입해도 인체에 치명적 손상을 준다. 또한 TDI 제조공정 중 포스겐은 염소와 일산화탄소를 고온으로 가열해 생산되는데 이때 높은 압력이 발생해 폭발할 위험이 있다. 1991년 9월 군산의 동양화학 TDA와 타르의 유출사고가 일어난 예가 있다. In addition, TDI (toluene diisocyanate) is used to produce colorless, low-viscosity, solid and mainly useful porous bodies as well as solid elastomers at room temperature. However, TDI (Toluene D-isocyanate) is produced by synthesizing phosgene with TDA, and is used as a raw material of polyurethane to make building insulation materials, chairs, automobile seats, rubber adhesives, textile treatments, artificial leather paints, and the like. The phosgene gas was used as a chemical weapon during the First and Second World Wars, causing pulmonary edema, lung cancer, and the like to death of 1.2 million people. In addition, during the TDI manufacturing process, phosgene is produced by heating chlorine and carbon monoxide at high temperature, and there is a risk of explosion due to high pressure. In September 1991, there was an accident of leaking TDA and tar in Gunsan.

따라서, 상기와 같이 제시된 이소시아네이트기를 포함한 것들 중에서 융점 및 안정성 등을 고려할 때 TDI TRIMER를 사용함이 가장 바람직하다.Therefore, it is most preferable to use TDI TRIMER in consideration of melting point and stability among those including the isocyanate groups presented above.

상기와 같은 방법에 의하여 제조된 우루시올을 함유한 고체혼합물을 BALL MILL에 넣고 24시간 분쇄하거나 AIR ZET MILL로 분쇄하여 200mesh 이상의 망으로 분급하여 분말옻을 생성하여, 상기 우루시올을 함유한 고체혼합물의 분말은 옻오름(알레르기)가 감소되어, PC, PE, PP, PA, ABS, PET, 아크릴, PES, PS, 실리콘, 실란트 등 각종 수지에 혼합하여 사출, 압출을 용이하게 하고, UV 도료, 우레탄 도료, 에폭시 도료, 소부 도료, INK, 분체도료 등 다양한 도료에 혼합하여 롤 코팅, 커튼 코팅, SPARAY, 실크스크린 인쇄, 옵셋 인쇄 등 다양한 공법으로 도포하여 항 균력과 원적외선 방사능력이 있는 제품을 생산 가능하도록 한다. The solid mixture containing urushiol prepared by the above method is put in a ball mill and pulverized for 24 hours or pulverized with AIR ZET MILL and classified into a mesh of 200 mesh or more to produce a powder lacquer, and the powder of the solid mixture containing urushiol Silver lacquer (allergy) is reduced, mixed with various resins such as PC, PE, PP, PA, ABS, PET, acrylic, PES, PS, silicone, sealant, etc. to facilitate injection and extrusion, UV paint, urethane paint , Epoxy paint, baking paint, INK, powder coating, etc., mixed with various coatings such as roll coating, curtain coating, sparray, silk screen printing, offset printing, etc. to produce products with anti-bacterial and far-infrared radiation ability. do.
