▎ 摘 要
NOVELTY - A polymer composite material comprises 100 pts. wt. prepolymer, 4-41 pts. wt. crosslinking agent, 1-40 pts. wt. functional polymer, 5-30 pts. wt. graphene, 3-30 pts. wt. carbon fiber, 2-25 pts. wt. coupling agent and/or silicone oil and 2-50 pts. wt. lubricating nanoparticles. The prepolymer is prepared by the polymerization of diisocyanate and diol. USE - Polymer composite material used for polymer composite bearing (claimed). ADVANTAGE - The polymer composite material has friction resistance, wear resistance, high hardness, high bearing capacity and excellent mechanical properties.
