| Abstract: |
| The influence of the CR/PU blending ratio，the addition level of sulfur，the type and addition level of carbon black and the type of plasticizer on the physical properties of CR/PU blend was investigated，and the optimized formulation of CR/PU blend was established.The optimized formulation of CR/PU blend was as follows：CR 80，PU 20，carbon black N220 30，zinc stearate 1，magnesium oxide 4，coumarone resin 5，sulfur 2，accelerator DM 3，accelerator M 3.This optimized formulation gave the blend better comprehensive physical properties. |
