摘　　要：使用废弃磺酸树脂作为添加剂,添加不同含量对聚丙烯材料进行改性,得到一系列磺酸树脂/聚丙烯复合材料。采用X射线衍射仪(XRD)、扫描电子显微镜(SEM)等手段对改性前后的聚丙烯复合材料进行表征,通过万能材料试验机和摆锤式冲击试验机等研究了复合材料的力学性能。研究结果表明:磺酸树脂的添加对聚丙烯材料的力学性能具有一定的提升作用,磺酸树脂添加量在5%时可达到最大的拉伸与冲击强度,最大拉伸强度可达31.92MPa,相比纯聚丙烯材料提高了6.08%,最大冲击强度可达5.06 kJ/m^(2),提高了31.4%。A series of sulfonate resin/polypropylene composites were obtained by using waste sulfonate resin as additive and adding different content of polypropylene materials. The polypropylene composites were characterized by X-ray diffraction(XRD) and scanning electron microscope(SEM). The mechanical properties of the composites were studied by universal material testing machine and pendulum impact testing machine. The results show that the addition of sulfonate resin can improve the mechanical properties of polypropylene materials to a certain extent. When the sulfonate resin content is 5%, the maximum tensile and impact strength can reach 31.92 MPa, which is 6.08% higher than that of pure polypropylene materials, and the maximum impact strength can reach 5.06 kJ/m^(2),which is 31.4% higher than that of pure polypropylene materials.
