Hereinafter, a silicone containing lacquer powder or a lacquer prepared using a mixture of urushiol and isocyanate (ISOCYANATE) according to the present invention and a manufacturing step thereof will be described in detail with reference to the accompanying drawings.

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 of isocyanate (S40), generating a solid mixture containing urushiol (S50); Grinding the solid mixture containing urushiol (S60); Classification step of the pulverized solid mixture (S70); In the production step (S80) of the urushiol-containing lacquer powder to prepare a lacquer powder as described above.

FIG. 2 is a view illustrating a method of preparing a lacquer powder or a lacquer liquid prepared in FIG. 1, that is, a lacquer-containing silicone. Heating step of the silicone mixture containing lacquer (S100); Curing step of the silicone mixture containing lacquer (S110); The lacquer-containing silicon is produced by the production step (S120) of the lacquer-containing silicon.

FIG. 3 illustrates in detail the mixing step (S40) of urushiol and isocyanate and the production step (S50) of a solid mixture containing urushiol in the process of FIG. 1 illustrating a process of preparing a lacquer powder. At this time, the isocyanate (ISOCYANATE) mixed with the urushiol in the mixing step (S40) of urushiol and the isocyanate may optionally use any one of toluene diisocyanate trimer and methylene diphenyl diisocyanate.

When using an isocyanate (ISOCYANATE) mixed with the urushiol as a toluene diisocyanate trimer, the toluene diisocyanate trimer, which is solid at room temperature, is thinner prior to the mixing step of the liquid urushiol and the solid toluene diisocyanate trimer. 1) and 1: 1 in a weight ratio of 40a to make a molten state, and then mixed with urushiol (40b), and to cure (40c) of the molten toluene diisocyanate trimer and urushiol mixture. The urushiol and toluene diisocyanate trimer are mixed in a weight ratio of 1: 0.8 to 1.2, and the most ideal ratio is 1: 1.

When using an isocyanate (ISOCYANATE) mixed with urushiol as methylene diphenyl diisocyanate, the urushiol and methylene diphenyl diisocyanate are mixed at a weight ratio of 1: 0.5 to 0.9 in the mixing step (40d) of the urushiol and methylene diphenyl diisocyanate. Mix and cure (40e). The most ideal weight ratio of urushiol and methylene diphenyl diisocyanate is 1: 0.75.

Urushiol-containing solid mixture prepared in the above step is put into a pulverizer and classified into a mesh of 200mesh or more to prepare a lacquer powder.

The raw lacquer or lacquer liquid used in the present invention may be either Korean, Chinese or Japanese, and the lacquer is centrifuged by mixing with the 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, natural raw lacquer can be used, but since the function of the lacquer is reduced by impurities such as rubbery and nitrogen compounds, centrifuged lacquer is used.

In addition, organic solvents such as acetone or xylene may be used instead of ethanol, but ethanol is environmentally and economically advantageous due to lower environmental harmfulness and lower boiling point than other organic solvents. At this time, if the mixing 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 completed.If the mixing ratio of the lacquer and ethanol exceeds 1: 1.2, the centrifugation is performed. 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 ratio of lacquer and ethanol is preferably 1: 0.8 to 1.2. Subsequently, centrifugation at 10,000 rpm or more, the solids in which rubbery and nitrogen compounds are deposited are settled in the lower layer, and it is possible to separate urushiol dissolved in ethanol in the upper layer. At this time, the urushiol and ethanol separated by centrifugation were heated under reduced pressure or vacuum at 40 ° C. to 100 ° C. to evaporate and remove ethanol and water to obtain only urushiol. When urushiol and isocyanate (ISOCYANATE) obtained here are mixed and stirred, a reaction takes place and turns into a solid. At this time, even if the urushiol and isocyanate (ISOCYANATE) is mixed in the same equivalent and left at room temperature, the reaction occurs, but when heated, a faster reaction occurs.

The isocyanate to be used may be any one having an isocyanate group (-N = C = O) such as toluene diisocyanate (TDI), methylene diphenyl diisocyanate, toluene diisocyanate trimer and the like. However, toluene diisocyanate is produced by synthesizing phosgene with toluene diamine (TDA), and is used as a raw material of polyurethane to make building insulation materials, chairs, car seats, rubber adhesives, textile treatments, artificial leather paints, and the like. The phosgene gas was used as a chemical weapon during World War I and World War II, which killed 1.2 million people, causing pulmonary edema and lung cancer. In addition, phosgene is produced by heating chlorine and carbon monoxide at a high temperature during toluene diisocyanate manufacturing process, and there is a risk of explosion due to high pressure. In September 1991, an accident occurred in Kunsan's Toyoene Toluene Diamine and Tar.

When isocyanate (ISOCYANATE) is used as methylene diphenyl diisocyanate, methylene diphenyl diisocyanate is liquid, so it is easy to mix with urushiol, but the ratio of 1: 0.5 ~ 0.9 with urushiol is suitable and the ideal ratio is 1 : 0.75. If the weight ratio of methylene diphenyl diisocyanate is less than 0.5, the mixture of urushiol and methylene diphenyl diisocyanate is molten to leave urushiol, and if it is greater than 0.9, methylene diphenyl diisocyanate is excessively high, and the effectiveness of lacquer is increased. Will fall.

Here, methylene diphenyl diisocyanate is produced by mixing a dicyclic monomer methylene diphenyl diisocyanate and polycyclic polyisocyanate (polymeric MDI), a white to pale yellow solid, aromatic hydrocarbon, chlorinated aromatic hydrocarbon Dissolves in nitrobenzene, acetone, ether, ethyl oxide, dioxane, etc., and relatively low corrosiveness at room temperature. It is prepared by reacting aniline with formalin for acid condensation and then reacting with phosgene.

In addition, when the isocyanate (ISOCYANATE) is used as the toluene diisocyanate trimer, the toluene diisocyanate trimer to be mixed before the mixing step of the urushiol and the isocyanate (ISOCYANATE), that is, the toluene diisocyanate trimer is solid, so that the mixing with the urushiol is easy. The thinner is mixed in a weight ratio of about 1: 1 to a molten state (S40a), and then the melt and urushiol of the toluene diisocyanate trimer are mixed (S40b).

At this time, the mixing ratio of urushiol and toluene diisocyanate trimer is suitably 1: 0.8 to 1.2 weight ratio, the most ideal weight ratio is 1: 1. When the weight ratio of the toluene diisocyanate trimer mixed with urushiol is less than 0.8, the mixture after the reaction is left in a molten state without being sufficiently reacted with urushiol, and when larger than 1.2, the toluene diisocyanate trimer is Excessive lacquer is less effective.

Therefore, it is preferable to use toluene diisocyanate trimer in consideration of melting point and stability among those including the isocyanate groups presented above. The weight ratio of the reaction should be considered the equivalent, urushiol 1: toluene diisocyanate trimer 0.8 to 1.2, methylene diphenyl diisocyanate is about 0.5 to 0.7, when the excess of isocyanate (ISOCYANATE) is less effective in lacquer As a result, unreacted urushiol remains when the reaction is underestimated.

When the lacquer powder produced above is mixed with 1 to 30% by weight of a silicone resin and heat cured, silicone is mixed with the lacquer powder.

At this time, the silicone mixed with lacquer generally includes various types of silicone rubber, pressure cooker, thermostat, packing, button, etc., such as wire coating, insulating tape, heat dissipating insulation sheet of transistor, calculator, home appliance, computer keyboard or anode cap of TV. , Milk bottle nipple, hose, packing of kimchi container, medicine bottle stopper, artificial heart organ, linkel tube, copier roll, release roll, sponge, etc.

The lacquer mixed with the silicone can be used both lacquer and lacquer powder, but the lacquer is more likely to cause skin allergy, and it is more preferable to use a lacquer powder having a low chance of allergic skin.

Hereinafter, the configuration of the present invention will be described in detail through the embodiment.
