摘　　要：加入不同的无机物对热硬化用铝磷酸盐铸造粘结剂进行复合改性。结果表明:一种铝镁硼复合磷酸盐铸造无机粘结剂具有良好的综合性能,该粘结剂的稳定性可达10个月,其热硬砂型(芯)具有较好的溃散性,较高的干强度,且在流动空气和高湿度下均有较好的抗吸湿性。The aluminum phosphate foundry inorganic binder for heat cured sand was compounded and modified by joining different inorganic substance. The results show that a kind of Al-Mg-B compound phosphate inorganic binder has good comprehensive properties, its stability can reach 10 months, its heat cured sand mould and core has good collapsibility, higher dry strength and good humidity resistance in flowing air and high humidity.
