Abstract

The invention discloses a building heat preservation material. The building heat preservation material is mainly prepared from, by weight, 15-30 parts of bentonite, 15-30 parts of coal ash, 10-20 parts of mica, 2-5 parts of polyacrylamide, 12-27 parts of kaolin, 11-25 parts of expanded perlite, 7-15 parts of phenolic resin, 0.5-2 parts of calcium stearate, 1-3 parts of foaming agent, 6-13 parts of soapstone, 35-55 parts of modified environment-friendly adhesive, 3-6 parts of starch ether, 6-13 parts of centrifugal glass fibers, 2-8 parts of hydroxymethyl propyl cellulose, 15-25 parts of cement, 8-17 parts of ceramsite and 11-23 parts of diatomite. The building heat preservation material is low in weight, can replace a traditional building heat preservation material, and can be used for coating protection of building side walls. The heat conductivity coefficient of the material is tested based on the GB / T10297-1998 standard, the heat conductivity coefficient is only 0.038-0.040, the heat preservation performance is extremely excellent, high acid-base corrosion resistance is achieved, no abnormities exist after the experimental test is carried out for 150 h, superhigh weather fastness is achieved, and no discoloring or pulverization or bubbles or stripping or cracks are generated 420 h later.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a building insulation material. Background technique [0002] With the implementation and development of building energy saving, heat preservation materials and products have attracted more and more attention. However, the materials currently used are not ideal in various properties, especially in terms of heat preservation, acid and alkali resistance, and weather resistance. At present, building insulation materials on the market generally have hidden dangers such as high specific gravity, high thermal conductivity, poor bonding performance, and easy peeling. [0003] The information disclosed in the background section is only intended to increase the understanding of the general background of the present invention, and should not be regarded as an acknowledgement or any form of suggestion that the information constitutes the prior art already known to those of ordinary skill in the ...
