Environment-friendly rustproof powder coating and preparing method thereof

Abstract

The invention discloses an environment-friendly rustproof powder coating. The environment-friendly rustproof powder coating is prepared from, by weight, 55-105 parts of GMA type acrylic resin, 45-110 parts of epoxy resin, 18-68 parts of absolute ethyl alcohol, 28-58 parts of linseed oil, 200-400 parts of methylbenzene solutions, 5-10 parts of titanium dioxide, 3-10 parts of degassing agents, 2-8 parts of flexibilizer and 1-15 parts of flatting agents. The environment-friendly rustproof powder coating in the technical scheme is high in purity and large in adhesive force, both the powder coating and the coating production process are free of three-waste pollution, and therefore the environment-friendly effect is good; the powder coating can be recovered and coated for the second time and is resistant to acid, alkali and abrasion and waterproof, and a rustproof film is smooth, long in service life and good in rustproof capacity.

Description

technical field

[0001] The invention belongs to the field of antirust materials for metal surfaces, and more specifically relates to a powder coating for antirust on metal surfaces and a preparation method of the coating. Background technique

[0002] Coating is a kind of chemical mixture coating that can firmly cover the surface of objects and play the role of antirust, waterproof, anticorrosion, acid resistance, alkali resistance, etc. It is widely used in modern technology and industrial fields. Generally speaking, a coating is a material that can be coated on the surface of the object to be coated and can form a solidly attached continuous film. It can be either inorganic, such as electroplating copper, electroplating nickel, electrogalvanizing, etc., or organic, such as Most organic polymer materials. Organic polymer materials constitute the main part of today's coatings market. There are many types of paints, and the types of paints used in different fields are not th...
