| Abstract: |
| The effects of the modified pyrophyllite on the properties of NR compound were experimentally investigated.The results showed that，the order of effect of the common modifiers on the physical properties of pyrophyllite filled NR vulcanizate was as follows：silane coupling agent KH-560＞titanate coupling agent NDZ-201＞silane coupling agent KH-550＞titanate coupling agent NDZ-101＞stearic acid；when the surface of pyrophyllite was modified by 1.5 phr silane coupling agent KH-560，and modified pyrophyllite/carbon black N330 blending ratio was 30/30，NR vulcanizate with the optimum comprehensive physical properties was obtained. |
