研究了橡塑合金中PVC用量、橡塑合金/氯醚橡胶并用比、硫化体系、补强体系及增塑体系等对耐低温、耐乙醇汽油橡胶材料性能的影响.结果 表明,随着PVC用量的上升,胶料的耐低温性能下降,耐乙醇汽油性能上升;当橡塑合金/氯醚橡胶并用比为80/20时,胶料的耐乙醇汽油性能最好;复合硫化体系胶料的脆性温度最低,体积变化率最小;当N330/N990并用比为30/20时,胶料的低温性能最好;加入TP-95的胶料拥有最好的低温性能和耐乙醇汽油性能.

In response to the shortcomings of cobalt-rich cathodes,iron-based perovskite oxides appear as promis-ing alternatives for solid oxide fuel cells(SOFCs).However,their inferior electrochemical performance at reduced temperatures(<700℃)becomes a major bottl
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.

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
