摘　　要：以SBR为基体橡胶、竹纤维为增强材料,通过偶联改性竹纤维表面制得竹纤维/SBR复合材料。利用万能试验机、扫描电镜(SEM)、无转子硫化仪分析偶联剂种类及用量、竹纤维粒径及用量对竹纤维/SBR复合材料硫化特性、力学性能的影响。结果表明:偶联剂的种类及用量对竹纤维/SBR复合材料的性能有一定的影响,其中铝酸酯偶联剂改性的竹纤维与SBR橡胶相容性最好,且用量为1%时,竹纤维/SBR复合材料拉伸强度最大;竹纤维粒径为140目、添加量为30份时,竹纤维/SBR复合材料综合性能最佳。With SBR as the base rubber and the bamboo fiber as the reinforced material,bamboo fiber / SBR composite could be prepared by the coupling modification of bamboo fiber surface. Effects of the types and dosage of the coupling agents,and the size and dosage of bamboo fiber on curing characteristics and mechanical properties of bamboo fiber / SBR composite have been analyzed through universal testing machine,SEM and no- rotor curometer. The results show that,the properties of bamboo fiber / SBR composite are affected by the types and dosage of the coupling agents: the best compatibility is achieved when bamboo fiber,through the aluminate coupling modification,and SBR rubber act together,and the maximum tensile strength of bamboo fiber / SBR composite achieved when the dosage of aluminate coupling agents is 1%; the best comprehensive properties of bamboo fiber / SBR composite are achieved when the size of bamboo fiber is 140 mesh and the dosage 30 portion.
