采用反应注射成型法制备了聚双环戊二烯(PDCPD)材料,力学性能测定结果表明所得材料具有较高韧性和刚性.利用MM-200摩擦试验机考察了PDCPD材料在干摩擦和液体石蜡润滑下的摩擦学性能,结果表明:干摩擦条件下,负荷在一定范围内时材料呈现黏着磨损,而当负荷较高时,发生严重的机械切削和塑性变形,呈现类似于疲劳磨损的磨损方式;液体石蜡润滑条件下,材料呈现典型的磨粒磨损,在所研究的负荷范围内表现出优良的摩擦学性能. Polycyclic dicyclopentadiene (PDCPD) was prepared by reaction injection molding method, and its mechanical properties were measured.The results showed that the obtained material possessed high toughness and rigidity.The MM-200 friction tester was used to study the mechanical properties of PDCPD under dry friction and liquid paraffin lubrication The results show that under dry friction condition, the material shows adhesive wear under a certain load range, while when the load is high, severe mechanical cutting and plastic deformation occur, showing a wear mode similar to that of fatigue wear. The liquid Under paraffin lubrication conditions, the material exhibits typical abrasive wear and exhibits excellent tribological properties over the range of loading studied.
