Heat storage brick as well as preparation method and application thereof
The invention discloses a heat storage brick as well as a preparation method and application thereof, and belongs to the field of heat storage materials. The heat storage brick contains 73-87 parts by weight of pyrophyllite tailings, 10-24 parts by weight of magnesia and 1-3 parts by weight of paper pulp waste liquid sediment. The pyrophyllite mine waste-pyrophyllite tailings are adopted as the raw material, the price is low, the pyrophyllite resource is effectively utilized, large-amount accumulation of the pyrophyllite tailings is avoided, and the environment is improved; meanwhile, the preparation process is simple, the pyrophyllite tailings are used for producing the magnesium iron heat storage material, the heat storage capacity is high, the compression strength can reach 45-70 Mpa, and the volume density reaches 2.0-2.5 g/cm < 3 >.
本发明公开了一种蓄热砖及其制备方法和应用，属于蓄热材料领域。本发明所述蓄热砖含有叶腊石尾矿73～87重量份、镁砂10～24重量份、纸浆废液沉淀物1‑3重量份。本发明采用叶腊石矿废弃物—叶腊石尾矿为原料，价格低廉，有效的利用叶腊石资源，避免了叶腊石尾矿的大量堆积，改善了环境；同时，制备工艺简单而利用叶腊石尾矿生产镁铁质蓄热材料蓄热能力强，耐压强度可达45～70Mpa，体积密度达到2.0～2.5g/cm3。
