摘　　要：研究了含镁改性剂对硼铝磷酸盐粘结剂及该粘结剂型(芯)砂性能的影响,结果表明:镁能提高硼铝磷酸盐粘结剂的粘结强度,特别是能改善硼铝磷酸盐粘结剂型(芯)砂在高湿度下的抗吸湿性。含镁改性剂也能明显改善含硼较高的硼铝磷酸盐粘结剂的稳定性。The effect of magnesium-containing modifier on the properties of boron aluminum phosphate binder and the binder-bonded heat-curing sand mold was studied. The results show that the magnesium-containing modifier can improve the bond strength of boron aluminum phosphate binder, and the humidity resistance of sand molds is improved especially. The magnesium-containing modifier can improve the stability of high boron binder as well.
