Using low level of starch and clay to replace the same level of carbon black,the clay/starch/carbon black/SBR composites were prepared,and the properties of composites were investigated.The results showed that,compared with those of carbon black/SBR composite,the tear strength and wet skid resistance of starch/carbon black/SBR composite increased,the number of tensile fatigue increased,the modulus and wear resistance decreased sharply,and compression temperature rise increased;compared with starch/carbon black/SBR composite,the modulus,wear resistance and wet skid resistance of clay/starch/carbon black/SBR composite were improved,and compression heat build-up decreased. |
