[0032] The high-strength composite expanded perlite building material of the present invention can be molded into standard boards or blocks by using prefabricated molds, and the molding process mainly includes steps such as preparation of slurry, casting, curing with molds and demoulding. The preparation of the slurry is to add water to the magnesia, various inorganic magnesium salts and expanded perlite according to the slurry raw material formula to prepare the slurry and stir it properly so that the surface of the expanded perlite is evenly wrapped with the slurry. When casting, the slurry can be directly Cast in a bottom mold with a smooth surface, or lay a release film on the bottom of the mold first, then cast the slurry and smooth the su...

Abstract

The present invention relates to a kind of building material. Magnesia, inorganic salts, expansion pearlite and water in certain proportion are mixed into slurry, and the slurry is molded in prefabricated mold into standard plate or block or in-situ cast into building in required shape. The mold is formed through the steps of compounding slurry, casting, curing in mold, curing outside mold and other steps. The building material of the present invention has relatively high compression strength and impact strength other than the light weight and good heat insulating performance, and is especially suitable for use as well material and floor heat insulating material.

Description

technical field [0001] The invention relates to an expanded perlite building material, in particular to a high-strength composite expanded perlite building material. Background technique [0002] Press, expanded perlite is a kind of glassy lava formed by acidic magma, and its products (such as cement expanded perlite products and water glass expanded perlite products) have the characteristics of small bulk density and low thermal conductivity, so they are often It is used as the roof insulation material of buildings and the insulation layer material of industrial pipelines or thermal equipment. Although the above-mentioned expanded perlite product has the advantages of light weight and good thermal insulation performance, it also has the defects of low strength and easy pulverization, so its application range is greatly limited. In the field of modern architecture, expanded perlite products are generally not used as building wall materials and floor insulation materials tha...
