摘　　要：以天然橡胶(NR)为基体材料,研究了系列稀土硫化物的种类对NR复合材料的硫化特性、力学性能、耐老化性能及耐磨性能的影响。结果表明,硫化镧铈的加入不仅可以缩短NR的硫化时间,加快了硫化速度,还可以大幅提高材料的力学性能、耐老化性能、耐磨性能等,性能提升效果远优于传统的硫化助剂HVA-2。The influence of various rare earth sulfides on the vulcanization characteristics,mechanical properties,aging resistance and wear resistance of natural rubber(NR)composites is investigated in this article,with NR being used as the matrix material.The results show that the vulcanization time of NR rubber is reduced and the vulcanization speed is increased by the addition of lanthanum cerium sulfide.Furthermore,the mechanical properties,aging resistance,wear resistance and other performance aspects of the composites are significantly enhanced.
