Abstract

The invention provides a FEVE fluorocarbon metal powder coating for metal surfaces and a preparation method thereof. The formula A component and B component are respectively prepared to obtain powder A and powder B, and according to a specific ratio, the A component powder is put into the reaction In the kettle, add wax additives and metal pigments in sequence, and then add component B powder, and stir evenly to obtain FEVE fluorocarbon metal powder coating. In the process of preparing the powder coating in the present invention, the surface viscosity of the powder particles can be reduced to a large extent, and the metallic pigment can be promoted to stick to the surface of the powder particle. sex. The coating does not lose gloss, does not pulverize, and is highly transparent, which solves the problem of metallic pigments being oxidized and blackened when exposed to the air, and the combination of component A and component B of the weather-resistant resin solves the problem of UV protection when used outdoors. The problem of light passing through the clear overcoat to degrade the primer.

Description

technical field [0001] The invention relates to the field of powder coating preparation, in particular to a FEVE fluorocarbon metal powder coating for metal surfaces and a preparation method thereof. Background technique [0002] In the surface treatment process of aluminum profiles, the electroplating method uses a large amount of strong acid, strong alkali and heavy metal solutions, including highly toxic chemicals such as cyanide and chromic anhydride, and the prepared powder coating is applied to the metal surface, which can replace the The heavy pollution process of electroplating protective layer on the metal surface is green and pollution-free, and the surface effect is the same as that of electroplating. [0003] Powder coating industry also has the powder coating kind of imitation electroplating effect, discloses a kind of imitation electroplating type powder coating and preparation method thereof as patent No. CN105086783B, makes the metal powder coating with elect...
