Abstract

The invention relates to a high-performance aqueous epoxy anticorrosive paint for steel structures, which is characterized in that the paint comprises a part A and a part B, wherein the mass ratio of the part A to the part B is 100: (30-40); the part A comprises the following components in percentage by weight: 20 to 45 percent of aqueous epoxy resin, 5 to 10 percent of rust-proofing pigment, 5 to 20 percent of tinting color, 20 to 45 percent of packing, 0.2 to 0.5 percent of thickener, 0.2 to 2 percent of flatting agent, 0.5 to 2.5 percent of other auxiliaries, and 20 to 40 percent of softened water; and the part B comprises the following components in percentage by weight: 20 to 40 percent of aqueous epoxy curing agent, 1 to 5 percent of neutralizer, 5 to 20 percent of aqueous cosolvent and 25 to 50 percent of rust-proofing pigment. The anticorrosive paint provided by the invention has the advantages of no environment pollution and high drying speed, and is safe and convenient for application.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a high-performance water-based epoxy anticorrosion paint for steel structures. Background technique [0002] Traditional anti-corrosion coatings are mostly solvent-based coatings. Common types include alkyd, epoxy, chlorinated rubber, acrylic, polyurethane and other types of coatings, which contain a large amount of organic solvents, which will be released during production and construction. It is harmful to the health of construction workers and pollutes the environment. Since the early 1970s, the development of environmentally friendly anti-corrosion and anti-rust paints such as high solid content, solvent-free, powder and water-based paints has been carried out in foreign countries. Among them, water-based paints have received more research because of their low cost, safe and convenient construction, and easy control of film thickness. . However, due to technical difficulties, great pr...
