Abstract

The invention discloses a preparation method of a stone-like furniture decorative coating. The preparation method comprises following steps: raw materials are subjected to pretreatment, wherein the raw materials such as shell powder are added according to a raw material mass ratio successively with stirring; auxiliary agents, such as 15 to 45 parts of an antifoaming agent, 15 to 45 parts of an anti-settling agent, are added, and a mixed solution is obtained via stirring; 55 to 75 parts of ethylene-vinyl acetate copolymerization emulsion adhesive, 10 to 50 parts of water-white rosin, 20 to 40 parts of polyacrylate water-retaining agent, 20 to 40 parts of polyurethane thickening agent, 20 to 40 part of dicyclohexyl phthalate plasticizer, and 40 to 70 parts of a color paste are added; an obtained mixed material is added into a material preparation tank slowly and uniformly, and the coating is obtained via continuous stirring; a substrate is coated with the coating; and finished products are obtained via drying and equilibrium of moisture. The stone-like furniture decorative coating prepared via the preparation method is green and friendly to the environment; no pollution is caused; adhesive force on the substrate, flexibility, and heat resistance are excellent; the stone-like furniture decorative coating is better than existing coatings, and application range is wide.

Description

Technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a preparation method of a stone-like furniture decoration coating. Background technique [0002] With the acceleration of China’s modernization and the improvement and improvement of people’s living standards, China’s indoor environment construction has made considerable progress, and people’s awareness of indoor environmental pollution has continued to increase. However, the overall level is still not optimistic, and indoor air pollution is still It is one of the main killers that endanger human health. It is urgent to strengthen governance. According to reports, the main sources of pollution in China's indoor environment come from buildings, decorations and furniture. Excessive pollution of formaldehyde, benzene, and ammonia has seriously affected people's health. Home improvement is inevitable, paint, paint, and wooden furniture are everywhere. At present, the existin...
