摘　　要：文章研究了酚醛树脂硬度、耐热温度、抗冲击强度对磨料磨具磨削性能的影响;分别通过双马来酰亚胺和蜜胺树脂对酚醛树脂进行了共混改性,并研究了其对磨具磨削性能的影响。研究发现,磨具的耐磨性与树脂的硬度和抗冲击强度正相关;磨具的磨削比跟树脂耐热温度、硬度和抗冲击强度正相关。加入5%体积双马来酰亚胺时,除PF-c外,其他树脂耐磨性和锋利性都有不同程度的增加。随着蜜胺树脂含量的增加,磨块的耐磨性逐渐降低,锋利性先增加后降低,磨削比逐渐下降。当MA∶酚醛为1∶1时具有最好的耐磨性;当MA∶酚醛为3∶1时具有最好的锋利性。The influences of hardness, heat resisting temperature and impact strength of phenolic resin on abrasive grinding performance have been investigated. The phenolic res in was modified by bismaleimide and melamine resin respectively, and the effect on abra sive grinding performance was studied. The results show that the wear resistance is posi tively correlated with the hardness and impact strength of the resin, and the grinding ratio is positively correlated with the heat resisting temperature, hardness and impact strength of the resin. Adding 5% volume bismaleimide, except Pf c, the wear resistance and sharpness of other resins have increased in varying degrees. With the increase of the con tent of melamine resin, the wear resistance gradually decreased, the sharpness increased and then decreased, and the grinding ratio decreased gradually. When the MA ： phenolic resin is 1 ： 1 , it has the best wear resistance, when the MA ： phenolic resin is 3 ： 1 , it has the best sharpness.
