摘　　要：根据金刚石涂附磨具的使用环境和特性,对其所用结合剂提出了柔韧性、耐热性、耐磨性好及对金刚石的把持力强等要求。通过对NM-1树脂的聚氨脂改性,再对NM-1和NM-2结合剂进行断裂延伸率、冲击强度、热重(TG)、耐磨性、断口扫描电镜等力学性能检测和分析,综合评定结合剂的各项性能,磨削试验亦证明了上述各项测试可对金刚石涂附磨具用结合剂进行的性能评价。According to the using environment and characteristics of coated diamond tools,the bond with better flexibility,higher heat resistance,higher wear resistance and better holding force are required.In this paper,the characteristics of the bonds are assessed by examining and analyzing fracture elongation,impact strength,TG,wear resistance and SEM of NM-1 with modified polyurethane and NM-2 resin bond.Grinding test also prove that the above indicators can evaluate the bond of coated diamond tools.
