Abstract

The invention discloses paint for projection and a preparation method of the paint. The paint comprises the following components in parts by mass: 20-30 parts of crylic acid, 30-40 parts of resin, 1-2 parts of microcrystalline cellulose, 3-5 parts of cellulose ether, 1-2 parts of borosilicate, 0.3-0.8 part of nano-powder, 2-4 parts of titanium dioxide, 2-4 parts of aromatic polyimide fiber, 1-2 parts of alkyl cyclohexyl bromobenzene, 1-3 parts of 4-n-pentyl-4'-cyanobiphenyl, 0.2-0.3 part of a defoaming agent, 2-4 parts of a dispersing agent, 0.2-0.4 part of a flatting agent, 0.2-0.5 part of N,N-dimethylethanolamine and 10-15 parts of 3-ethoxypropionic acid ethyl ester. The paint for projection and the preparation method of the paint, provided by the invention, have the benefits as follows: the reflecting property of a wall body during projection can be improved by the paint, the viewing angle balance is improved, the gain is increased, the projection effect is further improved, and the pain is environment-friendly, wear-resistant, flame-retardant and has a better stability.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a projection coating and a preparation method thereof. Background technique [0002] Coating refers to a class of liquid or solid materials that can form a thin film on the surface of an object under certain conditions for protection, decoration or other special functions. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials and an important industry in the chemical industry. [0003] With the development of society, people are doing more and more research on coatings, and their functions are further diversified. [0004] Now in our daily life, projection is becoming more and more popular. Or with the development of projection technology, it has gradually entered the family. On the one hand, projection has great requirements on...
