Anti-corrosion coating

Abstract

The invention discloses an anti-corrosion coating. The anti-corrosion coating comprises the following components in parts by weight: 3 parts of sodium silicate, 8 parts of allyl heptanoate, 5 parts of 2-methoxy-4-methylphenol, 1 part of selenium acetylacetonate, 3 parts of polyamide resin, 3 parts of 3-chloro-2-carboxylpropyl trimethylammonium chloride, 2 parts of chromium chloride, 6 parts of tetrachloroethylene, 6 parts of tetrabutylammonium bromide, 1 part of yttrium oxide and 7 parts of decabromodiphenyl ether. The anti-corrosion coating not only is convenient to use and has good brushing property but also is fast in film drying and has good mechanical properties and good acid and alkali resistance, water resistance and organic solvent resistance.

Description

technical field [0001] The invention relates to an anticorrosion paint. Background technique [0002] The film-forming substance of the anti-corrosion coating has chemical stability in the corrosive medium, and its standard is related to the composition and chemical structure of the film-forming substance, mainly to see whether it is easy to react with the corrosive medium or decompose in the medium under dry film conditions into small molecules. The shielding effect of anti-corrosion coatings is very important no matter from the perspective of electrochemical corrosion or pure isolation, and the shielding properties of paint films depend on the structural pores and coating pinholes of the film-forming substances, water, oxygen and ions. The penetration rate of the paint film is different. The penetration rate of water is much greater than that of ions. The transmission of oxygen is more complicated and has a great relationship with temperature. After water and oxygen pass...

Problems solved by technology

There are few ions passing through the paint film, and their direct effect on the substrate metal can be ignored, but it will increase the conductivity of the paint film. Therefore, it is particularly important to effectively prevent the medium from corroding the metal substrate. The existing paint There are many types, some are poor in acid and alkali resistance, some are more toxic, some have poor elasticity, and some have poor mechanical properties.
