Coal gangue sintered porous thermal-insulation brick
The invention provides a coal gangue sintered porous thermal-insulation brick, which is prepared from the following components in parts by weight: 50-65 parts of coal gangue, 15-25 parts of expanded and vitrified micro-beads, 5-15 parts of polycrystalline mullite fibers, 4-6 parts of bauxite, 20-35 parts of river sludge, 8-15 parts of a hardening modifier, and 5-7 parts of an acid-resistant aid. The porous brick fired by adopting the method has the advantages of light weight, low water absorption rate, low dry shrinkage rate and the like by adopting the expanded and vitrified micro-beads, theadded polycrystalline mullite fibers have the effects of heat preservation and heat insulation, and the preparation process is simple, energy-saving, emission-reducing, ecologically and environmentally friendly, and can prevent environmental pollution.
本发明提出了一种煤矸石烧结多孔保温砖，包括如下重量份组分：煤矸石50‑65份、膨胀玻化微珠15‑25份、多晶莫来石纤维5‑15份、铝矾土4‑6份，河淤泥20‑35份、增硬改性剂8‑15份、耐酸助剂5‑7份，采用本发明烧制的多孔砖采用膨胀玻化微珠具有质轻吸水率小、干缩率小等优点，其次增加多晶莫来石纤维具备保温、隔热功效，制备工艺简单；节能减排，防止环境污染，生态环保。
