Abstract

The invention discloses an acrylate copolymer emulsion, and belongs to the technical field of aqueous coatings. The acrylate copolymer emulsion comprises, by weight, 450-550 parts of deionized water, 1-2 parts of an anionic surfactant, 5-8 parts of a reactive emulsifier, 3-15 parts of hydroxypropyl acrylate, 50-160 parts of methyl methacrylate, 20-75 parts of butyl acrylate, 200-410 parts of styrene, 5-10 parts of methacrylic acid, 3-10 parts of an adhesion function monomer, 2-9 parts of a cross-linking monomer, 3-10 parts of a cross-linking agent, 0.1-3 parts of an antifoaming agent, 0.8-2 parts of an initiator, 3-5 parts of ammonia water, 0.8-2 parts of an antiseptic, 0.1-1 part of tert-butyl hydroperoxide and 0.1-0.8 parts of sodium bisulfate. The invention also discloses an aqueous industrial anticorrosive coating adopting the acrylate copolymer emulsion as a film forming substance. The coating has the advantages of high adhesion to a substrate, high water resistance and high salt spray resistance.

Description

technical field [0001] The invention belongs to the technical field of water-based coatings, and relates to an acrylic acid ester copolymer emulsion and a water-based industrial anticorrosion paint using the acrylic acid copolymer emulsion as a film-forming material. It is suitable for the manufacture of industrial anti-corrosion primers, as well as the base material for industrial anti-corrosion varnishes and paints. The water-based industrial paint prepared with this emulsion has excellent water resistance, salt spray resistance and high corrosion resistance. Hardness, can replace solvent-based alkyd paint for protective coating. Background technique [0002] With the rapid development of my country's environmental protection requirements, especially since the implementation of VOC emission consumption tax, the development of paint has been greatly restricted, and the consumption of water-based anti-corrosion industrial paint has increased rapidly. In 2014, the domestic co...
