Problems solved by technology

There are a large number of ethyl ester groups on the polyvinyl acetate polymer chain, and the water molecules in the air will be absorbed by the ethyl ester groups on the chain segment after the emulsion film is formed, thus making the polyvinyl acetate coating water resistant. not good

Abstract

The invention discloses a waterborne anti-corrosion vinyl acetate-acrylate copolymer latex coating. The coating comprises the following components in parts by weight: 100 parts of modified vinyl acetate-acrylate copolymer latex, 16-23 parts of mica iron oxide, 10-15 parts of filler, 5-9 parts of a dispersant, 3-5 parts of an adhesion promoter, 4-7 parts of an anti-skinning agent, 1-2 parts of a leveling agent, 5-9 parts of a thickening agent, 2-5 parts of an antioxidant and 30-40 parts of water. The anti-corrosion vinyl acetate-acrylate copolymer latex coating provided by the invention has excellent anti-corrosion performance, can form a dense protective layer on the surface of a metal device, can provide antifouling protection, effectively prolong the service life of the metal device, andis particularly suitable for anti-corrosion protection of ship hulls.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based anti-corrosion ethylene-propylene emulsion coating. Background technique [0002] The phenomenon of self-damage or deterioration caused by the chemical reaction or electrochemical reaction of metal and its surrounding environment is called corrosion, and the phenomenon of metal damage caused by physical, biological and mechanical factors is also collectively called corrosion. The mechanisms of metal corrosion are mainly four types: physical corrosion, chemical corrosion, electrochemical corrosion and microbial corrosion. According to relevant statistics, the annual economic loss caused by metal corrosion in the world is about 6 times the total economic loss caused by natural disasters such as earthquakes, floods and typhoons, which is a huge economic waste. Metal corrosion will not only bring huge economic losses to people, but also indirectly cause many accidents and perso...
