A silicone phenolic resin (SPF) was synthesized by transesterification using methyltrimethoxysilane(MTMS) as a modifier. The SPF was determined by FTIR analysis, TGA analysis, mechanical property test and other characterization methods. The results show that MTMS is successfully introduced into the structure of the resin; the resin has excellent heat-resistance, whose temperature at weight loss 10% is 462 ℃, 90 ℃ higher than that of ordinary phenolic resin(PF); the mechanical performance is obviously improved and the grinding ratio of superhard abrasive tools with SPF as resin binder is 51.1% higher than that of superhard abrasive tools with PF as resin binder. Meanwhile, the bending strength and impact strength of superhard abrasive tools with SPF as resin binder are 14.2% and 5.7% higher than that of another one, respectively.
