粘土/淀粉/炭黑/SBR复合材料的制备与性能研究

以少量淀粉和粘土等量替代炭黑，制备粘土/淀粉/炭黑/SBR复合材料，并对其性能进行研究。结果表明:与炭黑/SBR复合材料相比，淀粉/炭黑/SBR复合材料撕裂强度和抗湿滑性能提高，伸张疲劳次数增多，定伸应力和耐磨性能大幅下降，且压缩温升增大；与淀粉/炭黑/SBR复合材料相比，粘土/淀粉/炭黑/SBR复合材料定伸应力和耐磨性能提高，压缩生热降低且抗湿滑性能较好。;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
