Abstract

The invention relates to solvent-free high-impact normal temperature-cured epoxy anti-corrosion paint which comprises the following raw materials by weight percent: 30-50% of epoxy resin, 10-30% of cardanol curing agent, 2-10% of toughening agent, 0.1-1% of modified polysiloxane leveling agent, 0.01-0.1% of polysiloxane defoaming agent, 4-8% of polyacrylic ester dispersing agent, 3-11% of zinc phosphate, 3-8% of aluminum triphosphate, 6-15% of barite powder, 3-8% of titanium dioxide, 0.01-0.1% of carbon black, 3-8% of mica powder and 3-8% of talcum powder. The solvent-free high-impact normal temperature-cured epoxy anti-corrosion paint has the benefits as follows: the solvent-free high-impact normal temperature-cured epoxy anti-corrosion paint is an environment-friendly paint, the solid content is high, the thickness of a once formed film is large, the phenomenon of trickling is avoided, the paint film is non-toxic, and no pollutions can be caused to the environment; and the solvent-free high-impact normal temperature-cured epoxy anti-corrosion paint is strong in adhesive force and extremely strong in impact resistance, and can be used as the anti-corrosion paint for drinking water pipelines, sewage, brine and ore slurry conveying pipelines and inner walls of storage tanks.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a two-component solvent-free high-impact epoxy anti-corrosion coating cured at room temperature, which is suitable for anti-corrosion coatings on drinking water pipelines, pipelines containing corrosive media and the inner walls of storage tanks. Background technique [0002] The goal of the development of the modern coatings industry is to replace polluting, solvent-based products with high-performance, low-pollution products. The disadvantages of solvent-based anti-corrosion coatings are usually: (1) due to the volatilization of organic solvents, pores that are extremely unfavorable to anti-corrosion are easily formed in the coating; Explosive organic solvents are likely to cause fires or cause great harm to the health of construction personnel and workers; (3) Solvent-based coatings have high construction costs due to the large number of coatings and the long interval between...
