摘要
Abstract
The preparation of polyurethane composites with nano-clay blends was conducted through the pre-aggregation method.The tensile properties,wear resistance,thermal properties,and shape memory properties of modified polyurethane composites were tested to explore the effects of varying nanoclay content on the overall properties of polyurethane composites.The results show that the incorporation of nanoclay significantly improves the tensile properties and wear resistance of polyurethane composites,promotes the hydrogen bond interaction within polyurethane composites,increases the heat resistance of polyurethane composites,and improves the shape memory properties of composites.When the nanoclay content is 5%,the polyurethane composite achieves its highest tensile strength of 44.6 MPa and fracture elongation of 678.85%.The wear resistance is minimized at 51.22 mg,and the thermal degradation temperatures at 5%and 10%nanoclay content are 295.2℃and 325.4℃,respectively.Compared to pure polyurethane,nanoclay polyurethane composites exhibit excellent heat resistance,mechanical properties,and shape memory properties.关键词
