Abstract

The invention discloses a water-based epoxy enamel paint being a two-component coating which is prepared by epoxy resin emulsion, curing agents, tinting pigments, auxiliaries and so on. The water-based epoxy enamel paint has tough paint films and the advantages of excellent adhesion, flexibility, abrasive resistance and shock resistance and good chemical resistance, solvent resistance, water resistance, salt water resistance, durability and corrosion resistance. The water-based epoxy enamel paint is widely applied to the surface rust protection of ships, steel structures, wharf steel facilities and so on.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based epoxy enamel. Background technique [0002] As an important coating, epoxy paint is widely used in the coating anti-corrosion process due to its good anti-corrosion performance. Can be used as primer and intermediate coat for metal products. [0003] With the increasing demand for water-based epoxy coatings, especially the gradual increase in the quality requirements for epoxy topcoats, most of the epoxy anti-rust paints in the market are solvent-based coatings. During the curing process of the coating film, there is a large amount of solvent Volatility does not conform to the sustainable development policy of "low-carbon environmental protection, energy saving and emission reduction" formulated by the state. The new water-based epoxy topcoat has attracted people's attention and attention. However, my country's current research on water-based epoxy paint is in the initial ...
