摘　　要：介绍了铸造用接枝改性动物胶粘结剂的国内外发展状况,在分析铸造用动物胶粘结剂的接枝共聚原理的基础上,系统试验了乳化剂用量及乳化时间、引发剂加入量、反应温度与反应时间、交联剂加入量、丙烯酸甲酯加入量等因素对动物胶性能的影响,并确定了最佳接枝改性工艺。Developments of the graft-modified gelatin binder for foundry at home and abroad are presented. On the basis of basic principle of graft copolymerization of gelatin binder for foundry, the effects of the emulsifier amount, emulsifying time, initiator amount, reaction temperature and time, addition level of crosslinking agent and methylacrylic acid etc. on the properties of gelatin binder were studied systematically, the optimal parameters of graft copolymerization of gelatin binder with methylacrylic acid were also determined.
