Abstract

The invention discloses a building exterior wall heat insulation material, and relates to the technical field of heat insulation materials. The heat insulation material comprises: a raw material formed by mixing 12-18 parts of Portland cement, 10-14 parts of fly ash and 8-15 parts of quartz sands; 10-15 parts of gypsum powder; 7-13 parts of perlite; 5-9 parts of magnesium oxide; 7-10 parts of polystyrene particles; 1.0-2.0 parts of polyvinyl alcohol powder; and 0.1-0.8 parts of an assistant formed by mixing epoxy acrylate, amino resin and peppermint oil. The building exterior wall heat insulation material prepared through adopting the above technical scheme has the advantages of cost reduction and quality improvement.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a thermal insulation material used for building exterior walls. Background technique [0002] As a major energy-saving means in the field of environmental protection in my country, building energy-saving is being vigorously popularized across the country, and it is highly praised by the market because of its better energy-saving effect. [0003] The thermal insulation material in the prior art has high cost and low cohesiveness, resulting in poor versatility. The reason is that the thermal insulation material has a high water absorption rate, is easy to shrink and be softened, and causes a short mission life. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the present invention provides a thermal insulation material for building exterior walls, which improves product quality and market competitiveness by improvin...
