Abstract

The invention relates to an environment-friendly high-strength inorganic heat-insulating material and a preparation method therefor. The material is prepared from the following ingredients and raw materials in parts by weight: 50-70 parts of fly ash, 30-50 parts of mineral powder, 4-6 parts of water glass and 3.5-4 parts of H2O2; and the material is doped with resin fibers, wherein the doped amount of the resin fibers is 1.0-1.5kg/m<3>. The preparation method comprises the steps of firstly uniformly stirring the fly ash, the mineral powder, water, the water glass and polypropylene fibers, then, adding the H2O2 into the mixture, carrying out stirring for 10-15 seconds at the solution temperature of 25-30 DEG C so as to prepare slurry, then, pouring the slurry into a mold, and carrying out demolding until the height of the slurry does not change any more, thereby preparing the environment-friendly high-strength inorganic heat-insulating material. Compared with the prior art, the environment-friendly high-strength inorganic heat-insulating material and the preparation method therefor have the advantages that the used raw materials are sufficient and environment-friendly, the preparation process is simple, and the product is high in strength and good in heat insulation and dry contractibility resistance, so that the environment-friendly high-strength inorganic heat-insulating material has a very good application prospect as a novel building energy-saving material.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a green high-strength inorganic heat-insulating material and a preparation method thereof. Background technique [0002] The use of thermal insulation materials in buildings can reduce the amount of basic building materials, reduce the weight of the enclosure structure, greatly save energy and reduce consumption, which is of great significance for promoting the development of the construction industry, alleviating the energy crisis and improving the living standards of the people. New energy-saving building materials are the material basis for building energy conservation. Different from ordinary building materials, they must not only have the basic properties of light weight and high strength, but also have good thermal performance such as thermal insulation. In addition, new energy-saving building materials also require that non-renewable resources are mi...
