摘　　要：选用硅藻土、海泡石、高岭土、滑石粉作为复合耐火骨料,以水玻璃和快干硅溶胶作为复合粘结剂,海藻酸钠和羧甲基纤维素钠(CMC)作为复合悬浮剂,采用正交试验法和极差分析法确定了铝合金金属型铸造用水基涂料中各组份的最优配比,通过对涂料各项性能进行测定和试验验证发现,所得的最佳配方涂料性能良好,能够应用于实际生产中。Using diatomite,sepiolite,kaolin and talc as composite refractory aggregate,water glass and quick-drying silica sol as composite binder,sodium alginate and sodium carboxymethyl cellulose(CMC)as composite suspension agent,the optimal ratio of each component of metal mold water-based casting coating for aluminum alloy was determined by orthogonal test and range analysis method.The properties of the coatings were measured and verified by experiments.It was found that the best formulation of the coatings had good properties and could be used in practical production.
