| Abstract: | The clay was modified with MG49.The interaction between the modified clay and NR and the modification effect were studied through IR,SEM and the determinations of the bound rubber content, the apparent crosslinking density, the characterization value of the interaction strength of the boundary surface, the creep and the mechanical properties. The results showed that after using the clay modified dilutely with MG49, the bound rubber content was enhanced,the apparent crosslinking density was raised, the interaction strength of the boundary surface between day and NR was strengthened and the network structure and the mechanical properties of the vulcanizate were improved. |
