Abstract

The invention discloses a hydrophilic anti-rusting metal intermediate coating. The hydrophilic anti-rusting metal intermediate coating is prepared from, by weight, 21-56 parts of hexakis methoxyl melamine formaldehyde resin, 8-13 parts of 1,2-propylene glycol-1-monobutyl ether, 30-44 parts of vinyl tri(2-methoxyl ethyoxyl) silane, 7-15 parts of cetyltrimethylammonium bromide, 13-27 parts of isoprene, 1-9 parts of ammonium stearic acid, 2-22 parts of acetyl triethyl citrate, 5-10 parts of tetraethylenepentamine, 6-14 parts of maleic anhydride, 7-31 parts of sorbital, 16-26 parts of alkylphenol polyoxyethylene ether, 3-19 parts of moonstone powder and 11-28 parts of titanium dioxide. The prepared coating prepared through the method is environmentally friendly, free of toxicity, harmless to the human body, long in anti-rusting time and capable of being well combined with metal priming paint and face paint, the anti-rusting effect is ensured, meanwhile, the stripping strength of the coating is improved, and the thickness of the coating is reduced and ranges from 140 micrometers to 160 micrometers.

Description

technical field [0001] The invention relates to a metal coating, in particular to a hydrophilic rust-proof metal intermediate coating. 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 bonding performance of the existing metal intermediate paint and the metal primer or topcoat is general, which increases the strength of the paint film. Thick and prone to failure after prolonged use. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing metal medium paint has general bonding performance with the metal primer ...
