High-strength aluminum oxide light brick and preparation method thereof
The invention provides a high-strength aluminum oxide light brick and a preparation method thereof. The high-strength aluminum oxide light brick is prepared from the following raw materials in parts by weight: 50 to 80 parts of Al2O3 fine powder, 20 to 50 parts of alpha-Al2O3 micro powder, 5 to 30 parts of micro-nano pore forming agent, 5 to 20 parts of water and 0.1 to 5 parts of binding agent, the raw materials of the high-strength aluminum oxide light brick further comprise an auxiliary agent; according to the high-strength aluminum oxide light brick, under the dual effects of the micro-nano pore forming agent and the auxiliary agent, the sphericity degree of pores is generated and enhanced, so that the heat conductivity of the material is reduced, the compression strength of the material is improved, and the preparation method is simple in process, energy-saving and beneficial to industrial production.
本发明提供了一种高强氧化铝轻质砖及其制备方法，所述高强氧化铝轻质砖的原料包括50～80份的Al2O3细粉、20～50份的α‑Al2O3微粉，5～30份的微纳米造孔剂、5～20份的水以及0.1～5份的结合剂；所述高强氧化铝轻质砖的原料还包括助剂；所述高强氧化铝轻质砖在微纳米造孔剂和助剂的双重作用下，生成并加强了气孔球形度，从而降低了材料的热导率，提升了材料的耐压强度，所述制备方法工艺简单，节省能源，有利于工业化生产。
