Abstract
The invention belongs to waterborne epoxy ester metallic paint. Antirust paint comprises a finish and a primer, wherein the primer is prepared from the following substances: a Nopco dispersing agent, a base material wetting agent, an antifoaming agent, zinc phosphate, iron oxide red powder, barium sulfate, talc powder, aluminum magnesium silicate inorganic gel, a waterborne epoxy ester emulsion, a Dow multifunctional aid, propylene glycol monomethyl ether, a leveling agent, a waterborne drier, an alkali-soluble associative thickening agent and the balance of deionized water; and the finish is prepared from the following substances: aluminum magnesium silicate inorganic gel, a Nopco dispersing agent, a base material wetting agent, a leveling agent, an antifoaming agent, zinc phosphate, barium sulfate, propylene glycol, talc powder, a Dow multifunctional aid, a waterborne epoxy ester emulsion, an organosilicone modified acrylic emulsion, a bactericide, propylene glycol monomethyl ether, a thickening agent and the balance of deionized water. The waterborne epoxy ester metallic paint provided by the invention has relatively high mechanical stability and excellent pigment wettability, high gloss and perfect adhesion and good chemical resistance such as water resistance and salt fog resistance.
Description
technical field [0001] The invention belongs to the technical field of rust prevention for steel materials, and in particular relates to a water-based epoxy ester metal paint. Background technique [0002] In the anti-corrosion construction of steel, it is very important to choose the correct type of coating, which is related to the protective effect and service life of the coating on the coated material. Anti-rust paint is a kind of coating that can protect the metal surface from chemical or electrochemical corrosion of the atmosphere, acid and alkali, etc. The anti-rust paint used is roughly oily and water-based. Oil-based anti-rust paint contains toxic substances, which are more harmful to operators. Water-based metal anti-rust paint is non-toxic, but its chemical resistance such as water resistance and salt spray resistance is worse than that of oil-based anti-rust paint. Contents of the invention [0003] In order to solve the problems existing in the background tec...
