Abstract

The invention discloses a heat insulating coating for a building external wall, which is prepared from 40 to 50 parts of emulsion, 1 to 2 parts of N-hydroxymethyl acrylamide, 6 to 9 parts of fumed silica, 4 to 6 parts of water, 1 to 2 parts of titanate coupling agent, 7 to 14 parts of auxiliary, 7 to 9 parts of n-butyl acetate, 9 to 12 parts of heat insulating material and 5 to 10 parts of modified nano calcium carbonate, wherein the emulsion is mixed liquor of A-102 silicone acrylic emulsion and A-99 pure acrylic emulsion at the weight ratio of 1.5 to 1, the auxiliary is prepared form 1 to 2weight parts of bactericidal mildewcide, 1 to 3 weight parts of flatting agent, 1 to 3 weight parts of thickening agent and 4 to 6 weight parts of coalescing agent, and the heat insulating material isa mixture of hollow glass bead, expanded perlite and alumina silicate fibre at the weight ratio of 1 to 1 to 1. The coating provided by the invention has the advantages of high chemical resistance, good weather resistance, good heat insulating effect, high glossiness, long film service 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, ...
