Corundum mullite brick produced by utilizing recycled 95 alumina ceramic and preparation method of corundum mullite brick
The invention discloses a corundum-mullite brick produced by using recovered 95 alumina ceramics and a preparation method thereof, the corundum-mullite brick comprises the following components by weight: 40-70% of recovered 95 alumina ceramics, 20-60% of mixed powder, 1-8% of a binder, 1-8% of a binder, 1-8% of a binder, 1-5% of a binder, and 1-5% of a binder. The mixed powder comprises the following components in percentage by weight: 10-20% of sintered corundum, 5-20% of andalusite powder, 5-10% of pottery clay powder and 1-10% of calcined alumina micro powder. The recycled 95 aluminum oxide ceramic used in the invention is industrial waste and is used as a main raw material of the invention, so that the linear expansion rate and apparent porosity of a refractory product are reduced, the thermal shock resistance stability and wear resistance coefficient are improved, the raw material cost of the refractory material is reduced, comprehensive utilization of waste is realized, the resource utilization efficiency is improved, and the environmental protection concept is realized.
本发明公开了一种利用回收95氧化铝陶瓷生产的刚玉莫来石砖及其制备方法，所述刚玉莫来石砖的组分按重量百分比包括：回收95氧化铝陶瓷40～70％、混合粉20～60％份、结合剂1‑8％，所述混合粉的组分按重量百分比包括烧结刚玉10～20％、红柱石粉5～20％、陶土粉5～10％、煅烧氧化铝微粉1～10％。本发明所用的回收95氧化铝陶瓷为工业废弃物，用其作为本发明的主要原料，降低了耐火制品的线膨胀率和显气孔率、提高了抗热震稳定性和耐磨系数，又降低了耐火材料的原料成本，实现了废物的综合利用、提高资源利用效率，和环保理念。
