Low-volume-density mullite heat-insulating brick and preparation method thereof
The invention discloses a low-volume-density mullite heat-insulating brick which is mainly prepared from the following raw materials in parts by volume: 30-50 parts of sedimentation tank mud, 5-30 parts of aluminum oxide, 10-30 parts of an expanding agent, 20-35 parts of kaolin and 150-250 parts of polystyrene spheres. The volume density of the low-volume-density mullite heat-insulating brick is 0.55-0.65 g/cm<3>, the compressive strength is 1.0-2.5 MPa, and the change rate of a reheating line at (1510 DEG C * 24 hours) is +/- 0.5%; when the average temperature is 1000 DEG C, the heat conductivity coefficient is 0.21-0.3 W/(m.K). The invention further discloses a preparation method of the heat-insulating brick through extrusion molding, so that the production efficiency is high.
本发明公开了一种低体密莫来石隔热砖，其主要由以下体积份的原料制成：沉淀池泥30‑50份，氧化铝5‑30份，膨胀剂10‑30份，高岭土20‑35份，聚苯乙烯球150‑250份。所述低体密莫来石隔热砖的体积密度为0.55‑0.65g/cm，耐压强度为1.0‑2.5MPa，1510℃×24h重烧线变化率为±0.5％；平均温度1000℃时，导热系数为0.21‑0.3W/(m·K)。本发明还公开了一种上述隔热砖的制备方法，其采用挤出成型，生产效率高。
