Unburned coal gangue brick with good heat preservation effect and preparation method thereof
The invention discloses an unburned coal gangue brick with a good heat preservation effect. The unburned coal gangue brick is characterized by being prepared from the following raw materials in parts by weight: 50-60 parts of coal gangue, 5-8 parts of expanded and vitrified small balls, 8-10 parts of cement, 4-5 parts of lime, 2-4 parts of bauxite tailings, 1.5-2.5 parts of silicon carbide, 8-11 parts of cordierite, 4-6 parts of magnesium hydroxide, 6-8 parts of clay, 7-9 parts of pregelatinized starch, 7-9 parts of modifying agent and a proper amount of water. The unburned coal gangue brick disclosed by the invention is reasonable in formula and is innovative in process, an unburning process is adopted, and the raw materials are made into granules at first and are compression molded to reinforce the hardness of the brick; the modifying agent made by a special process is added, so that the unburned coal gangue brick has the effects of light weight, heat preservation, sound absorption and antibiosis, and the comprehensive performance of coal gangue brick is enhanced; the product disclosed by the invention has the advantages of light weight, high strength, heat preservation, heat insulation, sound insulation, low water absorption, energy saving, waste utilization, quick construction and the like, and thus is worth of large-area popularization.
