Waterborne epoxy floor coating

Abstract

The invention provides a waterborne epoxy floor coating, and relates to the technical field of coatings in the field of chemical industry. The waterborne epoxy floor coating comprises a component A and a component B. The component A comprises a high-performance silicone acrylic modified aqueous epoxy emulsion, a pigment filler, an auxiliary agent and deionized water, and the component B is a mixedmodified amine curing agent. According to the invention, the high-performance silicone acrylic modified waterborne epoxy emulsion is used as a basis; a mixed modified amine compound is used as a curing agent; the film-forming comprehensive performance can be matched with that of solvent type epoxy resin, wherein silicon-oxygen bonds in the system have relatively large bond energy and relatively small surface energy, so that the aging resistance, heat resistance, oil resistance, water resistance, precipitation resistance, medium resistance and electrical property of a polymer coating are improved, and the prepared anticorrosive coating reaches and exceeds corresponding indexes of common solvent-based coatings, and is an environment-friendly terrace coating.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based epoxy floor coating. Background technique [0002] The current anti-corrosion coatings are solvent-based, and solvent-based products contain a large amount of toxic volatile organic compound solvents, which directly volatilize during production and construction, pollute the environment and endanger human health. The development of water-based epoxy resin has gone through three stages. It is called type 1 water-based epoxy system, which basically does not contain organic solvents, but the coating has poor drying property, short pot life and unstable rheology; the second generation is type II water-based epoxy resin. The epoxy system contains some organic solvents as film-forming aids, which are harmful to the environment; the third-generation products are not yet the most mature, that is, vinyl hydrophilic groups are introduced into the epoxy resin to achieve epoxy ...

The development of water-based epoxy resin has gone through three stages. It is called type 1 water-based epoxy system, which basically does not contain organic solvents, but the coating has poor drying property, short pot life and unstable rheology; the second generation is type II water-based epoxy resin. The epoxy system contains some organic solvents as film-forming aids, which are harmful to the environment; the third-generation products are not yet the most mature, that is, vinyl hydrophilic groups are introduced into the epoxy resin to achieve epoxy self-emulsification effect, but the film-forming property is poor, and the comprehensive mechanical properties are not ideal enough to meet the market demand
