摘　　要：研究环氧化天然橡胶(ENR)用量对天然橡胶(NR)/ENR复合材料性能的影响。结果表明:ENR与NR并用后,NR/ENR复合材料的阻尼因子(tanδ)最大值和阻尼温域(tanδ>0.3)增大,tanδ最大值对应温度向低温方向移动;随着ENR用量的增大,NR/ENR复合材料的邵尔A型硬度、拉伸强度和拉断伸长率呈减小趋势,100%定伸应力呈增大趋势;当ENR用量为10份时,NR/ENR复合材料的tanδ最大值对应温度在25℃附近,其综合性能最佳。The effect of epoxidized natural rubber(ENR)dosage on the properties of natural rubber(NR)/ENR composites was studied.The results showed that after ENR and NR were blended,the maximum damping factor(tanδ)and damping temperature range(tanδ>0.3)of the NR/ENR composites increased,and the temperature corresponding to the maximum tanδmoved to a lower temperature.As the dosage of ENR increased,the shore A hardness,tensile strength and elongation at break of the NR/ENR composites tended to decrease,and the modulus at 100%elongation showed an increasing trend.When the ENR dosage was 10 phr,the temperature corresponding to the maximum tanδof the NR/ENR composites was around 25℃,and its comprehensive properties were the best.
