Abstract

The invention discloses waterproof thermal insulation coating. The waterproof thermal insulation coating comprises the following components: styrene-acrylic emulsion, silicone acrylic emulsion, hollowglass bead, a filling material, a nanometer thermal insulation powder, aerogel, glycol, hydroxyethyl cellulose, multifunctional additive AMP-95, a coalescing agent, a thickener, an additive, thixotropic agent magnesium aluminum silicate, aluminum sulfide, 4-phenyl butyl methyl dichlorodimethylsilane and deionized water. A preparation method comprises the following steps: adding water, the glycoland additive, then sequentially adding the coalescing agent, coalescing agents nanometer thermal insulation powder, aerogel, hydroxyethyl cellulose, thixotropic agent magnesium aluminum silicate, aluminum sulfide and 4-phenyl butyl methyl dichlorodimethylsilane, and performing sanding after the materials are uniformly dispersed; adding the hollow glass bead, styrene-acrylic emulsion, silicone acrylic emulsion, coalescing agent and multifunctional additive AMP-95, and adding the thickener, so as to obtain the waterproof thermal insulation coating. The waterproof thermal insulation coating has the advantages that the emulsion, aluminum sulfide, 4-phenyl butyl methyl dichlorodimethylsilane and other materials are mixed, and the formed coating is excellent in waterproofness, thermal insulationand stability.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a waterproof and thermal insulation coating and a preparation method thereof. Background technique [0002] Nowadays, with the rapid development of social science and technology and social production, energy and environment have become two major issues that people are increasingly paying attention to, so higher requirements are put forward for energy saving and environmental protection. Based on this, thermal insulation coatings came into being. It can effectively reduce the surface temperature and internal temperature of objects without consuming any external energy, so as to save energy, reduce energy consumption and improve safety. my country's existing construction area has reached more than 40 billion square meters 2 , more than 95% of them belong to high-energy buildings, and building energy consumption has reached more than 30% of the total energy consumption...
