Abstract

The invention relates to external wall elastic napping coating with thermal insulating function. The coating consists of the following components in percentage by weight: 40 to 50 percent of elastic acrylic emulsion, 10 to 15 percent of titanium white, 1 to 2 percent of freeze proof agent, 0.3 to 0.8 percent of defoamer, 0.1 to 0.15 percent of bacteriacide, 0.1 to 0.15 percent of wetting agent, 0.5 to 1 percent of film-forming additive, 0.1 to 0.2 percent of cellulosic thickener, 0.1 to 0.4 percent of dispersing agent, 1 to 1.5 percent of alkali swelling thickener, 3 to 5 percent of hollow glass microspheres, 5 to 8 percent of expanded perlite, 2 to 5 percent of vermiculite, 3 to 5 percent of sericite, 5 to 8 percent of coal ash filler, and 10 to 20 percent of water. Besides decorating and protection functions of conventional external elastic napping coating, the coating has the special function of thermal insulation.

Description

technical field [0001] The invention relates to an elastic brushed coating composition for exterior walls with the function of heat insulation and heat preservation. Background technique [0002] At present, energy conservation and emission reduction has become a very important task of the national government. In my country's construction industry, thermal insulation technical requirements were proposed as early as 20 years ago, and it has now become an industry standard. Especially in the extremely cold and hot regions of the north and south, building thermal insulation has become a mandatory requirement for the industry. In terms of construction, the specific measures for thermal insulation include internal thermal insulation of the inner wall and external thermal insulation of the outer wall, etc., mainly using foam boards for hanging board construction. [0003] Architectural coatings are indispensable decorative and protective functional materials in the construction i...
