Abstract

The invention discloses a cellular foam thermal-insulation material for fireproof walls, which comprises components, by weight ratio, 30 to 80 of sulphur aluminum cement, 15 to 30 of coal ash, 35 to 55 of water, 2 to 8 of hydrogen peroxide, 0.2 to 0.91 of stearin hard calcium, 0.1 to 1.39 of calcium powder and 0.5 to 2 of low-alkali glass fiber. The thermal-insulation material is an inorganic thermal-insulation material, thereby being small in appearance density and low in heat conductivity coefficient and having the advantages of being thermal-insulation, noncombustible, low in waste absorption rate and the like. Industrial waste is converted into benefits, so that the thermal-insulation material is a novel wall body material with high social benefits and economic benefits.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a wall thermal insulation material, and more specifically to a honeycomb foam material for external thermal insulation of a firewall and thermal insulation of a roof. Background technique [0002] At present, buildings in my country generally use benzene panels as external wall insulation materials. Benzene panels are chemical products, which are flammable, poor in durability, and release toxic gases after burning, which poses a serious threat to people's lives and property. In 2010, a fire with heavy casualties occurred in Shanghai, which was caused by the accidental fire caused by the use of benzene panels in the construction of the exterior walls. At present, there is an urgent need for a thermal insulation material with good thermal insulation performance, fire prevention and waterproof performance. Contents of the invention [0003] In order to solve the above technical ...
