Abstract

The invention provides a waterborne epoxy asphalt coating. The coating comprises a component A and a component B. The component A is prepared from the following raw materials in parts by weight: 15-18parts of deionized water, 0.2-0.5 part of a pH regulator, 0.3-0.5 part of anti-sagging auxiliary agent, 0.2-0.3 part of a wetting agent, 1.1-1.3 parts of a dispersing agent, 0.1-0.2 part of a defoaming agent, 3-5 parts of talcum powder, 10-13 parts of precipitated barium sulfate, 0.5 part of carbon black, 6-10 parts of iron oxide black, 3-5 parts of antirust pigment, 24-28 parts of epoxy resin, 4-6 parts of silica sol, 1-2 parts of propylene glycol monomethyl ether, 0.2-0.4 part of a flatting agent, 0.4-0.6 part of a flash rust inhibitor, 0.7-1 part of a thickener, 15-20 parts of emulsified asphalt and 2-3 parts of a coupling agent. The component B is an aliphatic amine modified polyamide polymer. The mass ratio of the component A to the component B is 12:1. The thickness of a film formedby one-time spraying of the coating can reach 150 microns, and the coating has excellent corrosion resistance, sagging resistance and chemical resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to water-based epoxy asphalt coatings, and meanwhile, the invention also relates to a preparation method of the coatings. Background technique [0002] As the public's requirements for environmental protection become more and more urgent and strict, the development of water-based heavy-duty anti-corrosion coatings with low energy consumption, low pollution and high performance has become one of the current research hotspots. The key to the research and development of water-based heavy-duty anti-corrosion coatings is the development of water-soluble film-forming resins. At present, anti-corrosion coatings such as water-based epoxy, water-based fluorocarbon and water-based polyurethane have been successfully developed. It conforms to the national development principle of "high efficiency, economy, environmental protection, safety and energy saving", and has a very broad application p...
