High-strength refractory material for incinerator lining and preparation method of high-strength refractory material
The invention relates to the field of refractory materials, in particular to a high-strength refractory material for an incinerator lining and a preparation method of the high-strength refractory material. The preparation method comprises the following steps: reacting L-2-amino-3-hydroxybutyric acid-3-phosphate with 2-acrylamide-2-methylpropanesulfonic acid to generate a phosphate monomer, and modifying a polycarboxylic acid water reducing agent by using the phosphate monomer as a third monomer to obtain the phosphate type water reducing agent. Lanthanum zirconate powder is prepared by using a coprecipitation method, and calcium carbonate is loaded on the outer layer of the lanthanum zirconate powder to obtain composite powder to improve heat resistance; the composite powder is mixed with high-aluminum aggregate, silicon carbide micro powder, alpha-aluminum oxide powder, silicon dioxide particles, Portland cement, spherical asphalt, a phosphate type water reducing agent, polypropylene fibers and yttrium oxide powder, and the high-strength and high-temperature-resistant refractory material is obtained and can be used for preparing an incinerator lining.
本发明涉及耐火材料领域，具体为一种焚烧炉内衬用高强度耐火材料及其制备方法。本发明将L‑2‑氨基‑3‑羟基丁酸‑3‑磷酸酯与2‑丙烯酰胺‑2‑甲基丙磺酸反应生成了磷酸酯单体，并将其作为第三单体对聚羧酸减水剂改性，得到磷酸酯型减水剂；使用共沉淀法制备锆酸镧粉体，并在其外层负载碳酸钙得到复合粉体以提高耐热性能；将复合粉体与高铝骨料、碳化硅微粉、α‑氧化铝粉体、二氧化硅颗粒、硅酸盐水泥、球状沥青、磷酸酯型减水剂、聚丙烯纤维、三氧化二钇粉体混合，得到具有高强度、耐高温的耐火材料，可用于制备焚烧炉内衬。
