Abstract

The invention discloses a two-component aqueous acrylate-epoxy resin hybrid coating. The epoxy resin part comprises 35-55 parts of an acrylate-epoxy resin hybrid emulsion, 5-10 parts of titanium dioxide, 1-5 parts of zinc oxide, 20-35 parts of a filler, 0.1-1 part of an adhesion promoter, 1.1-2.5 parts of an auxiliary agent and 1-11 parts of water. The curing agent part comprises 1-3 parts of aqueous organic amine. Through use of the hybrid system of an acrylate emulsion and epoxy resin, the anticorrosion coating with a fast drying rate, high film formation density, high weatherability and excellent salt mist resistance is prepared. Through formula optimization and curing agent mixing, the coating is a metal anticorrosion waterproof coating with a long service life, good application properties, good low temperature flexibility, good corrosion resistance, high hardness and good contamination resistance. The two-component aqueous acrylate-epoxy resin hybrid coating effectively prolongs a metal device usage time limit, can be used in terrace paint, saves a cost and provides a value for the society.

Description

technical field [0001] The invention belongs to the fields of industrial anticorrosion, metal roof anticorrosion, construction machinery anticorrosion and the field of floor coatings, and particularly relates to related anticorrosion and waterproof two-component coatings. Background technique [0002] As people pay more and more attention to environmental protection, the requirements for environmental protection are also getting higher and higher, which provides an opportunity for the water-based anti-corrosion coating. Solvent-based coatings release a large amount of solvents during production and construction, causing great harm to the environment. The use of environmentally friendly and low-pollution water-based coatings has become a mainstream trend in today's society. The performance of water-based resins prepared with a single structure is far inferior to that of solvent-based resins. For example, there is still a large gap between water-based industrial coatings prepa...
