Abstract

The invention relates to a coating and a preparation method thereof, the coating comprises the following raw material component mixture A: 40-45 parts of titanium dioxide sol, 15-20 parts of isocyanate, 30-40 parts of polyethylene glycol, 10-15 parts of cosolvent, 5-8 parts of talcum powder, 7-12 parts of silicon dioxide dispersion liquid, 5-15 parts of aluminum silicate fiber, 1.5-2 parts of isobutyl acrylate, 5-10 parts of allyl phosphate, 20-30 parts of copper pyrithione, 10-20 parts of film-forming agent, 1.6-2 parts of dispersing agent and 1-5 parts of polyethyleneimine; the coating is prepared under the cooperation of preparation process steps and technical parameters, and at least has the following advantages that the coating is high in glossiness, resistant to high temperature, good in surface hardness, high in corrosion resistance, good in adhesiveness, not prone to falling off, high in contact adhesive force with the metal surface, high in paint film hardness, good in coloring effect, not prone to agglomeration, good in color fastness, good in corrosion resistance and the like. The paint is suitable for surface treatment and decoration of various metals, and has good comprehensive performance even in a high-temperature environment, so that the performance of the paint is obviously improved.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a coating and a preparation method thereof. Background technique [0002] In industrial production and daily life, coatings are often used. Coatings are coated on the surface of objects to be protected or decorated, and can form a continuous film firmly attached to the object to protect and increase the performance of the product. The function is usually based on resin or oil or emulsion, and can be used as a viscous liquid prepared with organic solvents or water by adding pigments, fillers, and corresponding additives. The protection of metal materials that are easy to be corroded or rusted needs to be protected by coatings, especially for iron products, in order to improve the performance and prevent rusting, it needs to be sprayed, so that the products have high gloss, high temperature resistance, good surface hardness and corrosion resistance high sex. However, although the coatings...
