Abstract

Coating for a metal surface of a security door is composed of the following components, by mass, 60-70 parts of epoxy resin E-12, 40-45 parts of polyester resin, 20-25 parts of cellulose acetate butyrate, 50-55 parts of PU curing agents, 20-30 parts of trioctyl trimellitate, 10-15 parts of titanium dioxide, 25-30 parts of hexamethoxy methyl melamine, 0.05-1 part of fluorine-based alkyl polyether modified polysiloxane, 30-40 parts of p-toluene sulfonic acid n-butanol and 5-10 parts of ultraviolet absorbent UV-329. The coating is smooth in surface, the paint surface is smooth, a coating is high in adhesive force and not prone to stripping, the coating is long in service life and resists wear and acid-base corrosion, the loss is 0.01g after the coating is worn 10000 times, a paint film of the product is full, good in weather resistance and free of harming personal health of users, and the coating can be widely produced and can continuously replace existing materials.

Description

technical field [0001] The application belongs to the field of metal coatings, in particular to a metal panel coating for anti-theft doors.
