摘要：
Influences of additives on the physicochemical characteristics and technologies of binder are researched, and a new compound phosphate heat-cured foundry binder coded B8M15 is developed. The binder is made from environmental friendly inorganic materials such as phosphoric acid, aluminum hydroxide, B-ion additive and Mg-ion additive. Laboratory results indicate that combined effect of B-ion additive and Mg-ion additive can improve the storage stability of the binder and its sand mold or core, as well as they can increase the dry strength of its sand mold or core from 0.77MPa to 2.51MPa. This binder has low gas evolution and good collapsibility.
