摘　　要：分别以白炭黑、碳纳米管、碳微球及石墨烯为增强剂,对天然橡胶复合材料的制备以及其力学性能进行研究。采用传统机械混炼法将复合材料进行混合,通过平板硫化机进行交联制备天然橡胶复合材料。分别考察不同增强剂的含量对橡胶复合材料力学性能的影响,找到最佳的添加量。分析了不同种增强剂对复合材料力学性能的影响规律,对其增强效果进行对比说明。采用电子万能拉伸测试仪、邵氏硬度计对复合材料的拉伸性能和硬度性能进行分析,结果表明:复合材料的力学性能随着炭微球、碳纳米管和石墨烯含量的增加而增加,随着白炭黑的含量的增加而减少,碳纳米管和石墨烯的增强效果较好。The preparation and mechanical properties of natural rubber composite was carried out by using different kinds of enhancer such as white carbon black, carbon nanotube, carbon microsphere and graphene. Using traditional mechanical mixing method to mix the raw materials and then the composite was synthesized by beat condition on the plat snlfuration apparatus. The effects of the content of enhancer on mechanism performance of composite were investigated and then the optimized content of enhancer was obtained. The effects law of the content of enhancer on the ten- sile strength of composites was investigated. The general tensile tester and sclerometer were used to characterize the hardness and mechanism performance of the composites. The resuhs showed the mechanism properties of composites became stronger with the increasing of the carbon microsphere, carbon nanotube and grapheme, and became weakness with the increasing of white carbon black. The carbon nanotube and grapheme were better enhancers for the rubber.
