Preparation of Thermosetting Polyurethane Modified Materials and Their Abrasion Resistance
The study aims to explore the feasibility and advantages of applying thermoset polyurethane(PU)composites in protective coatings.A variety of modification methods were used in the study,including the preparation of polyurethane/polymethacrylate(PU/PMMA)composites by blending method,and the introduction of Kevlar fiber(Kevlar)reinforcement material modification.By evaluating the wear resistance of different materials,the results showed that polyurethane/polymethacrylate/Kevlar fibers(PU/PMMA/K)wear composites containing 20%(w)polymethacrylate(PMMA)and 1%(w)Kevlar fibers exhibited the best wear resistance.
