Foaming thermal-insulation fireproof brick produced by using coal gangue, and preparation method thereof
The invention relates to a high-strength foaming thermal-insulation brick produced by using coal gangue, and a preparation method thereof, wherein the raw materials comprise, by weight, 40-60 parts of coal gangue, 30-50 parts of bauxite tailings, 2-15 parts of fly ash, 0-15 parts of silica sand, and 0-1 part of a sulfurous acid paper pulp waste liquid. According to the present invention, with the foaming thermal-insulation fireproof brick produced by using the coal gangue as the main raw material, and the preparation method of the present invention, the problems of low fire resistance, poor molding, low strength and high cost of the light fireproof thermal-insulation brick in the current domestic market are solved, and the product has characteristics of light weight, thermal insulation and fire resistance, and can be widely used for important equipment in the glass-ceramic industry.
