Problems solved by technology

[0005] The present invention aims to solve the problems in the prior art that when the water-based acrylic resin is used as a film-forming material, it has a large odor and low weather resistance, and proposes a water-based coating with organic silicon-modified pure acrylic emulsion as the main film-forming material. It has the advantages of low odor, environmental friendliness and high weather resistance

Abstract

The invention discloses waterborne coating, and belongs to the technical field of coasting. The waterborne coating comprises, by weigh, 25-40 parts of organosilicone modified pure acrylic emulsion, 15-30 parts of waterborne polyurethane resin, 1-3 parts of expanded vermiculite, 4-12 parts of curing agents, 0.5-3 parts of functional agents, 0.5-3 parts of PH conditioning agents and 30-60 parts of deionized water. Compared with existing waterborne coating, the waterborne coating has the advantages of being high in weather fastness, capable of absorbing moisture and capable of emitting fragrance by itself, and can be used outdoors.

Description

technical field [0001] The invention relates to a water-based paint and belongs to the technical field of paint. Background technique [0002] Acrylic resin coatings have excellent process performance, mechanical properties and physical properties, and are widely used. However, the vast majority of acrylic resin coatings are solvent-based coatings, mostly viscous liquid or solid, insoluble in water, but soluble in organic solvents such as aromatic hydrocarbons and ketones, and organic solvents are volatile, flammable and explosive. , toxic, and cause great harm to the environment and human body. With the increasingly urgent and strict requirements for environmental protection, the requirements for the use of water-based coatings are increasing, and the application of water-based acrylic resin coatings is born. [0003] Acrylic emulsion is commonly used as the main film-forming substance in water-based paints, but its synthesis process contains other monomers s...
