High-strength coal gangue sintered porous brick and preparation method thereof
The invention discloses a high-strength coal gangue sintered porous brick. The high-strength coal gangue sintered porous brick is prepared from the following raw materials (by weight): 30-50 parts ofcoal gangue particles, 20-30 parts of river bottom silt, 10-20 parts of quartz sand, 10-20 parts of waste ceramic particles, 3-8 parts of glass powder, 5-10 parts of bentonite, 8-15 parts of mixed auxiliaries, 3-6 parts of asbestos fibers and 2-5 parts of sulfate. The mixed auxiliaries comprise the following components in percentage by mass: 5-15% of a flame retardant, 20-30% of an anti-freezing agent, 50-70% of a reinforcing agent and 3-5% of a binder. The preparation method comprises the following steps of: (1) pretreating raw materials; (2) weighing the raw materials; (3) conducting primarymixing; (4) aging; (5) secondary mixing; (6) preparing a blank; (7) drying; (8) sintering; and (9) conducting steam curing. The preparation process is scientific and reasonable, the adopted raw materials are easy to obtain, the production cost is controllable, and the raw material components are reasonably matched, so that the prepared porous brick is easy to form, has few cracks, good compactness and good strength, and has a heat preservation effect.
本发明公开了的一种高强度煤矸石烧结多孔砖,其原料按重量份计，包括煤矸石颗粒30～50份、河底淤泥20～30份、石英砂10～20份、废弃陶瓷颗粒10～20份、玻璃粉末3～8份、膨润土5～10份、混合助剂8～15份、石棉纤维3～6份和硫酸盐2～5份，所述混合助剂包括以下质量百分比含量的组分：阻燃剂5～15%、防冻剂20～30%、增强剂50～70%和粘结剂3～5%。其制作方法包括：①原料预处理；②原料称重；③一次混料；④陈化；⑤二次混料；⑥制坯；⑦烘干处理；⑧烧结和⑨蒸养。本发明的制作工艺科学合理，采用的原料易得，生产的成本可控，且各原料组分搭配合理，使得制得的多孔砖易成型、裂纹少、密实度好、强度好，且具有保温效果。
