采用拟反应注射成型法制备了含油聚双环戊二烯(PDCPD)材料.利用MMS-1G型摩擦磨损试验机考察了PDCPD材料在摩擦速率处于中高速(5～20 m/s)下的摩擦学性能.结果表明:含油PDCPD材料在中高速干摩擦下,表现出比纯PDCPD更优良的减摩耐磨性能.纯PDCPD材料的耐磨性受摩擦速率的影响相对较小,而PDCPD含油复合材料对摩擦速率更为敏感.在较低的摩擦速率下,纯PDCPD的磨损模式呈现明显的磨粒磨损;较高摩擦速率下,纯PDCPD主要为黏着磨损和微坑损伤.含油PDCPD材料具有完全不同于纯PDCPD的磨损模式,表现为轻微的表面擦伤和疲劳磨损.
Oil-bearing poly-dicyclopentadiene (PDCPD) was prepared by pseudo-reaction injection molding.The tribological properties of PDCPD at medium and high speed (5-20 m / s) were investigated by MMS-1G friction and wear tester The results show that the oil-repellent PDCPD material exhibits better friction and wear resistance than the pure PDCPD material at medium and high speed dry friction.The abrasion resistance of the pure PDCPD material is relatively less affected by the frictional velocity, while the PDCPD oil-containing composite material Which is more sensitive to the friction velocity.At low friction velocity, the wear mode of pure PDCPD shows obvious abrasive wear and the pure PDCPD is mainly adhesive wear and micro-pitting damage at higher friction velocity.The oil-containing PDCPD material has completely different In pure PDCPD wear mode, the performance of minor surface abrasion and fatigue wear.
