Abstract

The invention discloses a preparation method of an anti-static corrosion and rust prevention coating and belongs to the field of coatings. According to the preparation method, a waterborne epoxy resin prepolymer is obtained by use of polyethyleneglycol and epoxy resin, and organic montmorillonite, a conductive material, a foam killer, a dispersant and other additives are added into the waterborne epoxy resin prepolymer to prepare the anti-static corrosion and rust prevention coating. Epoxy resin and a curing agent are cross-linked and cured to form a film with a three-dimensional network-like structure, so that permeability to water, corrosive media and the like can be reduced, and the anti-corrosion performance of the anti-static corrosion and rust prevention coating is improved; as a carbon black conductive packing is also added, the anti-static corrosion and rust prevention coating has superior anti-static property.

Description

technical field [0001] The invention discloses a preparation method of an antistatic, anticorrosion and antirust coating, which belongs to the field of coatings. Background technique [0002] The annual loss caused by corrosion in the world is as high as more than 100 billion yuan, which involves various fields such as chemical industry, petroleum, transportation, electromechanical, mining, metallurgy, construction, food, light industry, etc. For this reason, effective measures must be taken To prevent corrosion, among these measures, the use of coatings for corrosion protection is the most economical, practical and convenient, so it has an absolute advantage in corrosion protection investment. [0003] Strictly speaking, anti-corrosion coatings should be classified as functional (special) coatings. my country has attached great importance to anti-corrosion coatings since liberation, and its development has roughly experienced three periods until now. In the first period, o...
