Anticorrosive metal primer

Abstract

The invention discloses an anticorrosive metal primer. The anticorrosive metal primer is prepared from, by weight, 10-23 parts of amino resin, 14-42 parts of polyester resin, 10-18 parts of 1,2-propylene glycol-1-monobutyl ether, 11-28 parts of diethyl carbonate, 35-52 parts of 2,2-di(4-hydroxyphenyl)propane, 9-21 parts of cethyl trimethyl ammonium bromide, 13-27 parts of isoprene, 2-13 parts of ammonium stearate, 8-20 parts of triethyl acetocitrate, 5-10 parts of tetraethylenepentamine, 5-15 parts of maleic anhydride, 14-22 parts of diacetone alcohol, and 8-27 parts of ethyl alcohol. The paint prepared from the metal primer is environmentally friendly, free of toxicity, harmless to people, capable of being well combined with the metal primer and a finishing coat, high in water resistance, capable of preventing color change of a metal surface, improving the peel strength of a paintcoat and guaranteeing the anticorrosive effect, and long in anticorrosive time.

Description

technical field [0001] The present invention relates to a paint for metal, especially a corrosion-resistant metal primer. Background technique [0002] In order to protect the metal surface and prolong the service life of the metal workpiece, the metal surface needs to be treated in the actual production process, such as improving the metal surface, cleaning the metal surface, derusting the metal surface, painting the metal surface, etc. , in the prior art, the protective effect of the metal intermediate paint applied on the metal primer and under the topcoat is better, but the existing metal primer and the metal substrate or the metal intermediate paint coated outside the metal primer The bonding performance is average, the water resistance is poor, and long-term use will easily lead to anti-corrosion failure. The inability to modify the brightness of the metal surface will cause the metal surface to become dull when it needs to be repainted. Contents of the invention ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing metal primer and the metal substrate or the metal paint coated outside the metal primer have general bonding performance, poor water resistance, long-term use will easily lead to corrosion failure, and cannot protect the metal surface. Modification of gloss level can lead to the problem of dull metal surface when it needs to be repainted
