Abstract

The invention discloses a preparation method of a corrosion-resistant imitation copper door coating. The preparation method comprises the following steps: adding epoxy resin and carboxyl-terminated saturated polyester resin into a stirring cylinder, and uniformly stirring at a low speed; adding ethyl acetate and petroleum asphalt under a stirring condition of 350-450 rpm; adding a leveling agent and calcium aluminate cement under a stirring condition of 600-800 rpm, and uniformly dispersing; adding iron oxide red and copper fine powder into a cylinder under a stirring condition of 350-450 rpmfor color matching; adding the rest raw materials, and uniformly stirring under a stirring condition of 1200-1500 rpm; and grinding, sieving with a 250-mesh sieve, and packaging. According to the corrosion-resistant imitation copper door coating, by adding the corrosion-resistant nano titanium dioxide and calcium aluminate cement with an interlayer structure, the corrosion resistance of the coating can be remarkably improved, the cracking is prevented; meanwhile, the iron oxide red, the liquid petroleum asphalt and the copper fine powder are mutually combined, and the color mixing effect is better.

Description

technical field [0001] The invention relates to the technical field of imitation copper paint, in particular to a method for preparing a corrosion-resistant imitation copper door paint. Background technique [0002] The imitation copper door is made of electrolytic plates, and the surface is sprayed with paint with a color similar to that of the copper door to make it look similar to the copper door, so it is called an imitation copper door. In order to achieve a beautiful and durable effect, most of the domestic anti-theft doors are made of imitation copper doors, and most of them adopt pickling and phosphating process before painting. Plates, forgings and cold plates are welded together, which causes certain difficulties for spraying, so a primer for degreasing and rust removal is required in the early stage. First: Primer. At present, most enterprises use electrostatic powder spraying as primer. Second: finish paint, which is now basically in several colors of red coppe...
