Abstract

The invention relates to a hydrophilic elastic waterborne emulsion paint. The emulsion paint comprises the following raw materials: water, a thickening agent, a pH value conditioning agent, a wetting agent, a dispersant, titanium dioxide, a filling material, an emulsion, a high-opacity polymer, a hydrophilic aid, a film forming aid, an anti-freezing agent, a bactericide, a mildew inhibitor, an antifoaming agent and an adhesion reinforcing agent. The hydrophilic elastic waterborne emulsion paint provided by the invention overcomes the disadvantage of poor resistance to soiling of current commercially-available elastic waterborne emulsion paints and has the advantage of excellent surface soiling resistance while maintaining good elasticity.

Description

technical field [0001] The invention relates to a hydrophilic elastic water-based latex paint and a preparation method thereof, which are applied in the field of paint. Background technique [0002] Elastic emulsion paint is made of elastic emulsion as a film-forming substance. Its coating film not only has the properties of ordinary paint, but also maintains high tensile strength, flexibility and elongation within a certain temperature range. The base material of the building is generally cement-based, which is affected by the ambient temperature, expands and shrinks heavily, and is prone to cracks, so elastic coatings are often used for construction. Elastic latex paint is welcomed by the market because of its good thermal expansion and cold contraction, which can effectively solve the micro cracks on the surface of the substrate. However, due to the elasticity of the paint film of elastic latex paint, the coating film is soft, especially in hot summer weather, the surfac...
