Abstract: |
The effect of coupling agent Si69 on the properties of silica/NR composites prepared by emulsion co-coagulation method was investigated.The results showed that,by adding coupling agent Si69 in the reaction which produced silica,the boundary interaction between silica and NR matrix was increased,the dispersion of silica in NR matrix was improved,and the physical properties of composites and dynamic property of compound were improved;the optimum addition level of coupling agent Si69 was 3 phr. |
