Problems solved by technology

Barrier-type coatings use the low thermal conductivity of the coating to block the conduction of heat. The coating is thicker, the construction requirements are high, and the stain resistance is not good.
The domestic reflective cooling coating has entered the market, but there is still a certain gap with the international advanced level

Abstract

The invention provides an environment-friendly scattering cooling macromolecular water-proof coating and a preparation method thereof. The environment-friendly scattering cooling macromolecular water-proof coating comprises polyacrylic ester, waterborne polyurethane, an organic silicone emulsion and polyethylene-vinyl acetate serving as main film forming matters; water is taken as a solvent; and a filler, a dispersing agent and a plasticizer are added. The environment-friendly scattering cooling macromolecular water-proof coating has unique heat dissipation and cooling performance and water-proofing performance, is resistant to ultraviolet radiation and aging, and can be made into various colors as required; and the defect of single colors of other water-proof coatings are overcome. The environment-friendly scattering cooling macromolecular water-proof coating has high bonding strength, good water-proofing and anti-leakage effects, heat resistance, freezing resistance and high extension performance, is applied to cold construction, brushed directly, easy to operate, and suitable for water proofing and cooling of new and old roofs of various buildings, basements, bathrooms, grain depots, water conservation dams, oil depots, swinging pools, tunnels, roads and bridges, courses, construction joints, expansion joints and the like.

Description

technical field [0001] The invention relates to a coating for construction, in particular to an environment-friendly scattering cooling polymer waterproof coating and a preparation method thereof. Background technique [0002] Waterproof coatings are painted on the surface of buildings, and a thin film is formed by the volatilization of solvent or water or the chemical reaction of the two components, so that the surface of the building is isolated from water, so as to play the role of waterproof and sealing. The viscous liquid is called waterproof coating. The waterproof film formed after the waterproof coating is cured has certain extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance, and can play the role of waterproof and sealing. The waterproof coating has good temperature adaptability, easy operation, easy repair and maintenance. [0003] Coatings with waterproof function on the market can be divided into reactive type, solvent typ...
