摘　　要：选用亚铝晶石粉、滑石粉、高岭土、冰晶石粉作为复合耐火骨料,以快干硅溶胶和聚乙烯醇(PVA)作为复合粘结剂,木质素磺酸钠和凹凸棒土作为复合悬浮剂,采用正交试验法和极差分析法确定了铸铁用水基消失模涂料中各组分的最优配比。通过对涂料各项性能进行测定、以及采用扫描电子显微镜对涂层的微观形貌和组织特征分析发现,涂料综合性能良好。Alumina spar powder, talc powder, kaolin and cryolite powder are used as composite refractory aggregates,quick-drying silica sol and polyvinyl alcohol(PVA) are used as composite binders, and sodium lignosulfonate and attapulgite are used as composite suspending agents, using the orthogonal test method and the range analysis method to determine the optimal ratio of each component in the water-based lost foam coating for cast iron. And the analysis results of tissue characteristics show that the comprehensive performance of the coating was good.
