Problems solved by technology

At present, inorganic building insulation materials on the market mainly include expanded perlite, aerated concrete blocks, sulphoaluminosilicate inorganic insulation boards, etc. The biggest advantage of this type of material is its strong fire resistance. The coefficients are all high, which is not conducive to large-scale promotion

Abstract

The invention provides a preparation method of an inorganic foam building thermal insulation material. The preparation method comprises the following steps: dispersing polypropylene fibers, pulverized fuel ash, sulphate aluminosilicate cement, calcium stearate, perlite, manganese dioxide and triethanolamine to water, and stirring, thus obtaining unfoamed slurry; and adding hydrogen peroxide with 30% of mass concentration to the unfoamed slurry, then molding the obtained pre-foamed slurry by casting, maintaining, demolding, and cutting, thus obtaining the inorganic foam building thermal insulation material. The preparation method has the advantages that the foaming process is controlled by controlling the mixing amount of the manganese dioxide catalyst so as to ensure the strength of the inorganic foam building thermal insulation material, simultaneously reduces the heat conductivity of the inorganic foam building thermal insulation material and enhances the heat preservation effect of the inorganic foam building thermal insulation material, the perlite is added so as to serve as an anti-collapse agent so as to reduce the rejection rate, and meanwhile, the triethanolamine is added so as to improve the property of the inorganic foam thermal insulation material. Compared with materials of the same kind, the inorganic foam building thermal insulation material has the characteristics of high strength, low heat conductivity, small volume weight, burning resistance, flame resistance and the like.

Description

technical field [0001] The invention relates to a preparation method of a building material, in particular to a preparation method of an inorganic foam building insulation material. Background technique [0002] At present, the commonly used building insulation materials at home and abroad are divided into two types: organic matter and inorganic matter. Organic building insulation materials include polystyrene foam (EPS, XPS), polyurethane rigid foam (PU), etc., which have the advantages of light weight, heat preservation, heat insulation, and waterproof. However, these organic foam materials are prone to aging and cannot last the same life as the building. During the service life of the building, the insulation layer needs to be replaced many times. In addition, EPS, XPS, PU, ​​etc. are polymer organic materials, which have defects such as flammability, low temperature resistance, fast burning speed, and a large amount of toxic gas, which poses a great fire hazard.
