Mullite refractory brick with high thermal shock resistance and production method thereof
The invention provides a mullite refractory brick with high thermal shock resistance and a production method thereof, and relates to the field of energy saving materials. The mullite refractory brickcomprises the following components in parts by weight: 40-50 parts of mullite, 10-15 parts of high-alumina bauxite clinker, 5-10 parts of coal gangue, 5-10 parts of Guangxi white mud, 5-10 parts of floating beads, 3-6 parts of kyanite, 2-5 parts of sillimanite, 1-3 parts of silicon carbide, 2-6 parts of carbon fibers, 1-3 parts of basalt fibers, 1-3 parts of aluminum silicate fibers, 10-15 parts of silica powder, 4-8 parts of polypropylene hollow spheres, 3-6 parts of argil, 5-10 parts of bentonite, 8-12 parts of aluminum oxide cement, 1-3 parts of a water reducing agent, 5-10 parts of guar gum, 3-6 parts of sodium metasilicate, 10-20 parts of polyvinyl alcohol and 180-200 parts of water. The mullite refractory brick provided by the invention has good thermal shock stability, the low creeprate, high refractoriness under load, high compressive strength and extremely high mechanical properties, can meet the design requirements of thermotechnical equipment such as metallurgy, building materials, petrifaction and electric power high-temperature kilns and pipelines, and has an extremely high application prospect.
