Anticorrosive paint

Abstract

The invention discloses anticorrosive paint which comprises, by mass, the following materials of 2-5 parts of allyl heptanoate, 1-4 parts of 4-methyl guaiacol, 1-2 parts of acetylacetone selenium, 4-9 parts of polyamide resin, 2-4 parts of 3-chlorine-2-carboxyl propyl trimethyl ammonium chloride, 1-3 parts of chromic chloride, 3-7 parts of vinylidene chloride, 2-5 parts of tetrabutylammonium bromide, 0.2-0.5 part of yttrium oxide, and 3-6 parts of decabromodiphenyl ether. The anticorrosive paint is not only convenient to use, easy to produce and manufacture, good in painting performance, and good in wettability for object surfaces, but also rapid in paint film drying, good in mechanical capacity, and good in acid-base resistance property, water resisting property, and resistance to organic solvent.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an anticorrosion coating. 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...

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.
