摘　　要：选用铝矾土耐火熟料和铬矿粉作为复合耐火骨料,以酚醛树脂和硅溶胶作为复合粘结剂,钠基膨润土和粉状羧甲基纤维素钠(CMC)作为复合悬浮剂,通过正交试验确定消失模铸钢水基涂料的最佳配比,即钠基膨润土含量5%,粉状羧甲基纤维素钠0.5%,酚醛树脂2%,硅溶胶含量5%,并进行生产验证。结果表明,该涂料具有良好的工艺性能,解决了现有涂料在使用过程中存在的粘砂,气孔等问题,能够很好地满足实际生产需要,且成本低廉。Selecting bauxite refractory aggregate and chromium slag as composite refractory aggregate, phenolic resin and silica sol as composite binder, and sodium bentonite and powdered sodium carboxymethyl cellulose （CMC） as composite suspension agent, the best ratio in EPC water-based paint was determined through the orthogonal test and production validation, that is sodium bentonite content 5%, CMC 0.5%, resin 2%, silica sol content 5%. The results show that, the coating has good processing performance, the problems of paint in the process of using sand, porosity and other issues were solved, which can better meet the needs of practical production, and the cost is low.
