Cement fly ash foaming composite heat insulation material

Abstract

The invention relates to a cement fly ash foaming composite heat insulation material, which comprises a cement fly ash foaming heat insulation outer layer, a sandwich composite layer and a cement fly ash foaming heat insulation inner layer, wherein the sandwich composite layer is positioned between the cement fly ash foaming heat insulation outer layer and the cement fly ash foaming heat insulation inner layer; the cement fly ash foaming heat insulation inner layer is connected with a building concrete body; and the sandwich composite layer is prepared from a polyphenyl board (ERS board), an extruded toluene board (XPS board), hard foam polyurethane and polyphenyl granular slurry. The heat insulation material has the advantages that: the problem that the fly ash of a power plant pollutes the environment is solved; the industrial waste is prepared into the building energy-saving heat insulation material so as to solve the problem of waste consumption for the state, save the energy and change waste into valuable; the heat insulation material is a multi-purpose energy-saving heat insulation material, and can be used for heat insulation of a building peripheral structure; and the construction difficulty is solved, and the construction quality is ensured.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a cement fly ash foaming composite thermal insulation material. Background technique [0002] At present, building energy-saving materials on the market are single light-weight thermal insulation materials. Building roof insulation requires repeated construction, such as insulation layer, leveling layer, and slope layer, etc. The process is complicated, the thermal insulation effect is poor, and the construction is difficult. , are prone to cracking, falling off, water seepage and other problems, and cannot meet the requirements of the national building energy conservation and environmental protection. Contents of the invention [0003] The object of the present invention is to provide a cement fly ash foaming composite thermal insulation material, which overcomes the disadvantages of existing building energy-saving thermal insulation materials such as easy cracking, falling off...
