以丁苯橡胶(SBR)为基体,N-N亚甲基双丙烯酰(MBA)为硫化剂,通过机械共混法制备了酰胺键交联的SBR混炼胶,并研究了不同用量的MBA对SBR复合材料硫化特性、力学性能的影响,以及在碱性条件下能否解交联,并利用FT-IR、SEM对水解前后的复合材料进行表征.结果 表明,在其他添加剂用量不变的情况下,当MBA用量为6份时,酰胺化制备的SBR硫化胶的力学性能最佳,拉伸强度达到5MPa,拉断伸长率为167.55%,Shore A硬度为55.由水解实验发现,橡胶在碱性条件下会发生水解,有一定量的质量损失,力学性能下降.FT-IR与SEM分析表明,该胶料中的酰胺交联键发生了水解,表面变得粗糙.

采用固体润滑剂(两种不同粒径的石墨Gr、石墨烯GN、二硫化钼MoS2、聚四氟乙烯PTFE)制备了NBR/SiC复合材料,研究了干摩擦条件下不同固体润滑剂对NBR/SiC复合材料摩擦磨损性能的影响.结果 表明,与其他润滑剂相比,GN可提高材料在硫化过程中的MH,且添加GN的NBR/SiC复合材料的力学性能最好;在相同实验条件下,添加GN的NBR/SiC复合材料的摩擦系数和体积磨损量最低,且磨损表面较为光滑平整,PTFE对NBR/SiC复合材料的摩擦磨损性能改善较小.
