Description

Polymer composition using lacquer solution and its manufacturing method {Manufacturing method and high polymer composite using lacquer sap}

The present invention relates to a polymer composition and a method for producing the same using lacquer.

Lac has been used wisely by our ancestors for thousands of years. Lacquer is a unique plant that has both weakness and toxicity.

In recent years, the value of lacquer is highly valued. It is proven that antibacterial, deodorant, antibacterial, insect repellent, and anti-cancer properties are excellent.

The lacquer, the sap collected from the bark on the lacquer tree, is a physiological secretion of the plant. The fresh lacquer, which has just been collected, is an off-white oily liquid with a sweet and astringent taste.

The main component of the lacquer, lactate or urushiol, is solidified by enzymatic reaction when it is connected with oxygen in the air, and has been used as an old paste by forming an excellent coating film of a polymer having a three-dimensional structure uniquely with other paints.

The main component of the urushiol lacquer is a polyphenol derivatives, initially with a material forming a coating film with black sides by the action of an oxidizing element in contact to air colorless and transparent one, formula C ₂₁ H ₃₄ O ₂ It is a viscous colorless liquid with a breaking point of 210 to 222 ° C (0.4 to 0.6 mm Hg). In the air, it turns black and solidifies. The structural formula of urushiol, which is not a single compound but a dihydric phenol mixture and is a main component, is as follows.

In the structural formula of urushiol, the side chain R is represented by (CH2) 14CH3 (CH2) 7CH = CH (CH2) 6CH2. (CH2) CH = CHCH2CHCH = CH (CH2) CH3. (CH2) 7CH = CHCH2CH = CHCH2CH = CH2 Known as four kinds of mixtures.

Urushiiol, which is a lipid component of fresh rusks collected from lacquer trees, is firstly oxidized by lacase, a dehydrogenase enzyme in ricotta sap. Subsequently, the unsaturated side chain in urushiol is converted to the quinone compound in humid air, and peroxides are generated, and the oxides are automatically oxidized to form complex network structures. Urushiol exhibits antioxidant properties with two hydroxyl groups (—OH) as in the above structural formula. Succulents also have reduced antioxidant levels due to enzyme polymerization, which also reduces antioxidant activity. Therefore, the automatic oxidation occurs in two stages as the lacquer is polymerized, which can be confirmed by measuring the antioxidant properties and hydroxyl value.

Urushiol (Phenolic Compounds) + O2 (Air)-Laccase (Oxidase)-> Quinone compounds + H2O2 ..... ①

Qunone compound + Protein, Amino acid, other organic acids, etc .--> Network structure + H2O2 .... ②

When lacquer breaks down the skin, uricol and laccase, which are the components of lacquer, are applied to the skin, causing allergic dermatitis that occurs when urushiol is oxidized by oxidation and catalysis of laccase in the air and reacts with skin protein. Those who are weak will have lacquer rise.

According to the report so far, the dry liquid is very difficult to dry, so it is difficult to dry by heat or artificially, and it is dried only at the appropriate moisture and temperature conditions.

Once upon a time, when our lacquer was lacquered with lacquer liquor, lacquer liquor was mixed with lacquer liquor in a certain proportion, and lacquer liquor was dissolved in a humid place during the summer rainy season.

Today, in order to lacquer lacquer (lactose) on lacquer columns, lacquer juice is mixed with terepin oil at a constant rate to maintain humidity of 70% to 75%, and the lacquer is dried at a temperature of 20 ℃ to 25 ℃. have.

It is mixed within 20% by weight based on the base, and the mixed solution of the polymer and lacquer sap is molded and dried to manufacture the lacquer (Lacquer) component excellent in flame resistance, heat resistance, waterproof, antiseptic, insect repellent and insulation Composite resin and its manufacturing method are described,

Korean Patent Publication No. 1003342930000 (20020413) discloses that <1> 20% by weight of a purified lacquer sap is dissolved in an organic solvent at a concentration of 10% by weight of a polymeric material used as a synthetic resin. It is obtained by mixing within, and then drying the mixed solution of the polymer and the lacquer sap, or by drying the polymer material used as a synthetic resin to the polymer melting temperature to form a polymer melt, the lacquer sap to the weight of the polymer Flame resistance, heat resistance and water resistance obtained by mixing and mixing in an amount of less than 20% by weight to form a mixed melt of polymer and lacquer, melt extrusion through a slit die, and then rapidly cooled and solidified in a roller Lacquer component with excellent antiseptic, insect repellent and insulation properties is mixed with existing synthetic resins, especially polyethylene (bl) ending) A functional synthetic resin and a method of manufacturing the same are disclosed,

Korean Patent Publication No. 1008420320000 (20080623) discloses a urethaneol-containing lacquer powder or lacquer prepared by pulverizing a solid mixture produced after a mixture reaction of urushiol and isocyanate (ISOCYANATE) and curing with a silicone sealant or acrylic sealant. It can be seen that the lacquer-containing sealant and its manufacturing method are disclosed.

In general, lacquer is not soluble in water, it is not dried by heat and hardens when left in the air. Problems that are not developed for industrial use is a problem to be solved by the present invention.

In order to solve the problems as described above, the present invention is to develop a lacquer-free technology and toxicity to dry lacquer juice without using humidity or oil, that is, calendula oil or terepine oil to dry lacquer juice, then using the lacquer Lacquer composition can be mixed with a certain ratio of Monama or various supporting materials to polymerize the resin, so that a new resin can be prepared in the lacquer composition. It is also possible to provide a polymer composition using a lacquer solution capable of preparing a lacquer composition by mixing a lacquer solution and a urea and catalyzing a peroxide, and a method for solving the problem.

The present invention is to remove the toxicity by oxidizing the lacquer juice and to prepare a lacquer juice difficult to dry conditions to prepare a polymer composition using the lacquer liquid functional lacquer chemical fiber yarn or plastic and film, etc.

There is an effect that can be used in antibacterial and environmentally friendly and health-friendly products.

The present invention is a condition that the lacquer is dried well regardless of heat and humidity temperature in the lacquer solution (seven liquor) 7% to 10% to 30% moisture content of urushiol which causes toxicity of lacquer It was found that trace amounts of nitrogenous compounds, which cause toxicity, were completely oxidized to remove the toxicity and dry well.

Urushiol contained in lacquer juice is mixed with a strong oxidizing agent in lacquer juice at a constant rate and then stirred slowly while maintaining a constant temperature for about 2 hours to completely oxidize urushiol containing lacquer juice.

In order to mix the oxidized lacquer liquor with various resin polymerization raw materials, a new lacquer resin is mixed by mixing it in a certain proportion to raw materials or monoma used in the polymerization of resins such as PET (polyester), nylon, acryl resin, PE, PP, and PC.
