摘　　要：以天然胶乳浸润槟榔纤维,制备天然橡胶(NR)复合材料,研究偶联剂Si69-纳米氧化锌改性槟榔纤维对NR复合材料性能的影响。结果表明:与未改性槟榔纤维的NR复合材料相比,偶联剂Si69-纳米氧化锌改性槟榔纤维的NR复合材料的物理性能、耐溶剂性能和抗湿滑性能改善,剪切模量减小,滚动阻力提高;偶联剂Si69-纳米氧化锌改性槟榔纤维的NR复合材料的综合性能优于偶联剂Si69和纳米氧化锌单独改性槟榔纤维的NR复合材料。Natural rubber(NR)composites was prepared by impregnating areca fiber with natural latex.The effect of areca fiber modified by coupling agent Si69-nano zinc oxide on the properties of NR composites was investigated.The results showed that,compared with NR composites with unmodified areca fiber,the physical properties,solvent resistance and wet sliding resistance of NR composites with the areca fiber modified by coupling agent Si69-nano zinc oxide were improved,the shear modulus was reduced,and the rolling resistance increased.The overall performance of the NR composites with the areca fiber modified by coupling agent Si69-nano zinc oxide was better than that of the NR composites with the areca fiber modified by coupling agent Si69 or nano zinc oxide alone.
