以超高分子量聚乙烯(UHMWPE)微粒为填料,制备氟橡胶复合材料的混炼胶,并利用硫化仪表征其硫化历程,在分析橡胶复合材料力学性能的基础上,研究特定工况下填料对该材料的摩擦、磨损行为的影响。结果表明:随着UHMWPE微粒用量增加,氟橡胶混炼胶的硫化速率下降,焦烧时间延长,其复合材料硬度增加,而拉伸强度下降且稳定在7±0.5MPa;UHMWPE微粒的添加能够提高该橡胶材料的耐磨性能,当UHMWPE填料含量为5份时,摩擦系数和磨损率均较低。
The UHMWPE particles were used as fillers to prepare the rubber compound of fluororubber composites. The vulcanization process was characterized by a vulcanizer. Based on the analysis of the mechanical properties of the rubber composites, The material’s friction and wear behavior are affected. The results showed that with the increase of the amount of UHMWPE particles, the vulcanization rate of fluoroelastomer rubber compound decreased, the scorch time prolonged, the hardness of composite material increased while the tensile strength decreased and stabilized at 7 ± 0.5 MPa. The addition of UHMWPE particles increased The wear resistance of the rubber material, when the UHMWPE filler content of 5 parts, the friction coefficient and wear rate are low.
