Abstract

The present invention discloses an aerogel modified inorganic insulation mortar. The aerogel composite fiber insulation material comprises and is complex processed by silicate cement, silicon dioxide aerogel particles, expanded vitreous microbeads, silica fume, redispersible latex powder, polypropylene fibers, cellulose ethers, and wood fiber. Compared with the existing inorganic insulation mortar, the aerogel modified inorganic insulation mortar has better insulation and construction performance, and can replace the existing inorganic insulation system and be widely applied in the energy saving field of building interior and exterior walls.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an airgel modified inorganic thermal insulation mortar. Background technique [0002] my country is the largest developing country in the world, and its energy consumption continues to increase. Building energy consumption has become one of the most important energy consumption units in my country, accounting for about 30% of the total energy consumption in society, and 60% of the energy loss is caused by building walls. Therefore, one of the most important measures for building energy saving is to carry out energy-saving technical transformation and innovation on the wall and establish a thermal insulation system. Among the traditional thermal insulation materials, the organic thermal insulation material system occupies the vast majority of the market share due to its excellent thermal insulation effect, light material density, and ease of operation. Although orga...
