Problems solved by technology

[0005] The technical problems mainly solved by the present invention: With the rapid development of the petrochemical industry, the amount of oil storage and transportation pipelines is increasing continuously, the leakage of oil products due to corrosion of storage tanks and pipelines, and the static electricity generated during the storage and transportation of oil In order to solve the problems of accidents such as explosions or fires caused by charges, a water-based epoxy resin prepolymer obtained by using polyethylene glycol and epoxy resin is provided, and organic montmorillonite, conductive materials and defoaming agents are added to it. Additives such as additives can be used to prepare antistatic anticorrosion and antirust coatings. In the coatings prepared by the present invention, epoxy resin and curing agent can be crosslinked and cured to form a coating film with a three-dimensional network structure, which can reduce the impact on water, corrosive media, etc. Permeability improves its anti-corrosion performance, and carbon black conductive filler is added to make the coating have excellent anti-static performance

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...
