Thermal-insulation and toughened burn-free colliery wastes brick and preparation method thereof
The invention discloses a thermal-insulation and toughened burn-free colliery wastes brick. The thermal-insulation and toughened burn-free colliery wastes brick is characterized by being prepared from the following raw materials in parts by weight: 50-60 parts of colliery wastes, 7.5-9.5 parts of Portland cement, 1-2 parts of sodium bicarbonate, 10-12 parts of riverway sludge, 4-6 parts of waste glass powder, 2-3 parts of calcined lime, 7-9 parts of papermaking black liquid, 4-5 parts of EVA emulsion, 2-3 parts of expanded glass bead, 4-5 parts of palm skin, 7-9 parts of modifier and a proper amount of water. The colliery wastes brick is reasonable in formula. By adding the palm skin, the colliery wastes brick is light and porous and the toughness of the product is enhanced; by adding the expanded glass bead, the thermal insulation property of the product is enhanced; and by adding the modifier prepared by a special process, the brick has the effects of lightness, thermal insulation, sound absorption and antibacterial property, and the comprehensive performance of the colliery wastes brick is enhanced. By utilizing the burn-free process, the environmental pollution is reduced, and the energy consumption is lowered; besides, the brick is light, good in toughness and high in tensile strength, has the function of wall thermal insulation, and is beneficial for thermal insulation of building walls.
