Problems solved by technology

However, the chemical pollution of the pickling and phosphating process will cause huge damage to the environment.
The strong acid treatment solution will pollute the farmland and stop the production of crops, and the phosphating treatment solution will cause eutrophication of the water body if it is not properly treated, and a large number of algae will appear, which will affect the ecology of the water body
The sewage treatment standard requires a rather complicated process
In recent years, environmentally friendly phosphating substitute products (zirconium series, silane treatment) hav

Abstract

The invention discloses an anticorrosive coating applied to a metal surface. Characterized in that it is characterized in that it comprises, the composition comprises the following components in partsby weight, 50 to 70 parts of epoxy resin, 40 to 90 parts of high-chlorinated polymer, ; 40 to 60 parts of ethylene resin, 50 to 90 parts of graphene, 50 to 90 parts of nano kaolin, 40 to 80 parts ofenvironment-friendly antirust pigment, 80 to 90 parts of nano silicon dioxide, 50 to 60 parts of methyltriethoxysilane, 70 to 90 parts of diaminodiphenylsulfone, 70 to 80 parts of thiodiethylene glycol, 50 to 80 parts of a film-forming agent, 50 to 90 parts of flatting agent and 70 to 90 parts of cured resin. Compared with the prior art, the invention has the following beneficial effects: the paint can be directly sprayed on a metal substrate without acid pickling, phosphatization and other pretreatment, is subversive change of the traditional paint spraying process, and thoroughly solves thechemical pollution generated by pretreatment; the solid content of the coating can reach 78.7%, the solvent is reduced, and good environmental protection performance is shown; and the weather resistance is excellent.

Description

technical field [0001] The invention relates to the field of spray protection decoration, in particular to an anticorrosion paint applied on a metal surface and an application process thereof. Background technique [0002] The current metal or hardware surface spraying still relies heavily on the pre-treatment process of pickling and phosphating, so that the coating can have a good bonding force with the surface of the workpiece and produce products that meet the requirements. There is usually an oxide layer on the surface of the metal or product workpiece itself, which will affect the bonding force with the coating. In order to remove the oxide layer, it is necessary to pickle the workpiece to enhance the corrosion resistance and bonding force of the workpiece. However, the chemical pollution of the pickling and phosphating process will cause great damage to the environment. The strong acid treatment solution will cause the farmland to pollute the crops to stop production,...
