Thermal shock resistant and wear resistant castable and preparation method thereof
The invention discloses a thermal shock resistant and wear resistant castable and a preparation method thereof, and relates to the field of unshaped refractory materials. The thermal-shock-resistant and wear-resistant castable is prepared by adding water into a mixture, uniformly stirring and then curing, the mixture comprises a matrix material and aggregate, and the matrix material comprises silicon dioxide micro powder, mullite particles, silicon carbide powder and modified steel fibers; the modified steel fibers are prepared by treating steel fibers with zinc sulfate and then coating the surfaces of the steel fibers with micro-nano flaky zinc phosphate with polydopamine; the aggregate comprises gypsum, aluminum micro powder, silicon micro powder, aluminate cement, sodium hexametaphosphate and a self-made water reducing agent; the self-made water reducing agent is modified polyurethane, the modified polyurethane is prepared by performing polycondensation on dimethylolbutyric acid, a hydroxyl monomer of polyethylene glycol ether and an isocyanate monomer to form long-chain polyurethane, and then cross-linking the long-chain polyurethane with hydroxyl-terminated hyperbranched polyester, so that the breaking strength is enhanced.
本发明公开了一种抗热震耐磨浇注料及其制备方法，涉及不定形耐火材料领域。本发明制备的抗热震耐磨浇注料，是向混合料中加入水，搅拌均匀后进行固化制得，混合料包括基质料和骨料，基质料包括二氧化硅微粉、莫来石颗粒、碳化硅粉和改性钢纤维；改性钢纤维是将钢纤维用了硫酸锌处理后，再在钢纤维表面用聚多巴胺包覆微纳米片状磷酸锌制得；骨料包括石膏、铝微粉、硅微粉、铝酸盐水泥、六偏磷酸钠和自制减水剂；自制减水剂为改性聚氨酯，改性聚氨酯是以二羟甲基丁酸、聚乙二醇醚的羟基单体和异氰酸酯单体缩聚后形成了长链聚氨酯，再与端羟基超支化聚酯交联制得，增强抗折强度。
