Abstract

A kind of anticorrosion asphalt-based epoxy resin water paint is proportionally prepared from modified asphalt emulsion, epoxy resin emulsion, solidifying agent emulsion, filler, assistant and water. Its advantages are high hardness, resistance to corrosion and abrasion, adhesion and softening point, and low pollution.

Description

technical field [0001] The invention relates to an anti-corrosion paint and a preparation method thereof, in particular to a water-based asphalt-based epoxy resin anti-corrosion paint and a preparation method thereof. Background technique [0002] In recent years, as various countries in the world have higher and higher requirements for emission restrictions on organic volatile compounds, the coatings industry has begun to develop in the direction of high solid content, powder coatings, water-based coatings, and light-curing coatings. To some extent, the amount of volatile organic compounds has become a criterion for evaluating whether a coating is an environmentally friendly coating. Water replaces toxic and harmful organic solvents. It has the advantages of non-toxicity, flame retardancy, no pollution to the environment, and energy saving. It is gradually replacing traditional solvent-based coatings and represents the development direction of coatings. [0003] Petroleum ...
