Abstract

The invention discloses a heat insulation and heat preservation coating for a building external wall. The coating is prepared from 40-50 parts of emulsion, 1-2 parts of N-hydroxymethyl acrylamide, 6-9 parts of fumed silica, 4-6 parts of water, 1-2 parts of a titanate coupling agent, 7-14 parts of auxiliaries, 7-9 parts of acetic acid n-butyl ester, 9-12 parts of expanded perlite and 5-10 parts of nano-calcium carbonate, wherein the emulsion is mixed liquid prepared from A-102 silicone-acrylate emulsion and A-99 pure acrylic emulsion according to the weight ratio of 1.5:1, and the auxiliaries are composed of, by weight, 1-2 parts of a sterilizing and mildew preventing agent, 1-3 parts of a leveling agent, 1-3 parts of a thickening agent and 4-6 parts of a film forming aid. The coating has the advantages of being high in chemical resistance, good in weather resistance and heat insulation and heat preservation effect, high in glossiness, long in coating film life and the like.

Description

technical field [0001] The invention relates to a thermal insulation coating, in particular to a thermal insulation coating for building exterior walls and a preparation method thereof, belonging to the technical field of chemical composition and its preparation. Background technique [0002] Due to the increasingly developed world industry and the destruction of nature by humans, energy conservation and consumption reduction has attracted the attention and attention of countries all over the world. my country's building energy consumption accounts for more than 30% of human energy consumption. Improve the thermal insulation performance of buildings and improve The use function of buildings, energy saving and consumption reduction are another important considerations in the design of building material selection. In the field of architectural coatings, the development goals at home and abroad are also developing in the direction of high efficiency, energy and resource saving, ...
