Antimicrobial mildewproof mothproof finish paint for furniture and preparation method thereof

Abstract

The invention discloses an antimicrobial mildewproof mothproof finish paint for furniture. The finish paint is prepared from the following raw materials in parts by weight: 160-200 parts of modified water-based polyurethane, 4-7 parts of calcium petroleum sulfonate, 1-2 parts of dioctyl azelate, 4-7 parts of antimicrobial corrosion-resistant aid, 10-13 parts of polytetrafluoroethylene wax, 2-3 parts of dimethyl silicone oil, 6-8 parts of thickener, 2-3 parts of ammonium polyphosphate, 10-17 parts of nano silicon dioxide and 6-8 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate. The aluminum isopropoxide is used as a precursor to prepare the aluminasol, the added polyvinylidene fluoride resin has favorable chemical corrosion resistance, high temperature resistance, oxidation resistance, weather resistance and ray radiation resistance and can form a stable corrosion-resistant coated film on the furniture board surface, and the polyvinylidene fluoride resin and aluminasol are blended for modification, thereby enhancing the water resistance of the furniture surface. The chinaberry bark powder, benzotriazole and the like are used as the antimicrobial corrosion-resistant aids to improve the odor of the furniture paint and perform favorable antimicrobial and preservative effects; and thus, the finish paint has the advantages of favorable environment friendliness and low cost.

Description

technical field [0001] The invention relates to a finish paint, in particular to an antibacterial, mildew-proof and moth-proof finish paint for furniture and a preparation method thereof. Background technique [0002] According to its gloss, water-based wood coatings can be divided into matte, semi-matte and glossy. At present, matte varnishes are widely used in the furniture coating market. Because of their soft gloss and delicate touch, they are favored by consumers. However, in the actual formula design, there are many problems in the water-based matte varnish, such as the matting powder is not easy to disperse, the storage stability of the paint, the transparency of the final coating film, etc., especially in dark walnut, black brown wood and other deep It is especially obvious on colored substrates, which are often accompanied by disadvantages such as fog, blue light, and whitening, which restrict the market development confidence of water-based wood coatings. At prese...

AI Technical Summary

Problems solved by technology

However, in the actual formula design, there are many problems in the water-based matte varnish, such as the matting powder is not easy to disperse, the storage stability of the paint, the transparency of the final coating film, etc., especially in dark walnut, black brown wood and other deep It is especially obvious on colored substrates, which are often accompanied by problems such as fog, blue light, and whitening, which restrict the market development confidence of water-based wood coatings

At present, the evaluation of the transparency of wood coatings largely depends on the accumulated experience of paint practitioners, and there is a lack of corresponding testing standards, which also increases the subjectivity in the evaluation methods, so that the further optimization of the formula is greatly affected by the subjectivity;

[0003] Although alkyd polyurethane white topcoats for wooden furniture on the market have good decorative effects, they contain substances harmful to human health such as benzene, and solvents and a small amount of free TDI remain for a long time, are not easy to volatilize, and the odor is difficult to eliminate

Therefore, it is particularly necessary to develop new furniture paint products that are benzene-free, odor-free, low-free TDI, and harmless to human health. Secondly, most furniture is made of wood and plastic panels. If the antibacterial and anti-corrosion properties are poor, the service life of furniture products will be greatly reduced. , Some furniture is in a long-term humid environment, which will accelerate the damage of the furniture. Therefore, it is necessary to improve the antibacterial and antiseptic performance of the surface of the furniture
