| 目的 以PE, PP为原料，接枝马来酸酐（MAH）后，与高岭土经双螺杆挤出机熔融共混挤出，制备PE-g-MAH/PP/高岭土复合材料。方法 采用电子万能试验机分析复合材料的拉伸性能；采用电子悬臂冲击实验机分析材料的缺口冲击强度；采用水平垂直燃烧仪测试分析复合材料的阻燃性；采用红外光谱仪分析复合材料的化学结构。结果 含MAH质量分数为5%的PE与PP按质量比1∶1混合后，加入15%的高岭土，制备的PE-g-MAH/PP/高岭土复合材料拉伸强度、缺口冲击强度和断裂伸长率均为最佳，分别为10.925 MPa, 40.6 kJ/m2, 89.5%；复合材料的阻燃性与高岭土加入量呈先快速增大后慢速降低趋势，加入量为15%时阻燃性最好；复合材料各组分间实现了化学键合。结论 适量的高岭土提升了PE/PP复合材料的阻燃性，而MAH的加入改善了PE, PP和高岭土间的相容性。 |

| The work aims to prepare PE-g-MAH/PP/ kaolin composite material with PE and PP as main raw material through grafting maleic anhydride (MAH) and filling Kaolin by melt blending technology. The tensile property of composite material was studied through the electronic universal testing machine. The impact strength was analyzed by the electronic universal testing machine. The non-flame property of composite material was analyzed by horizontal vertical combustion apparatus. The grafted copolymer structure was analyzed by infrared spectroscopy. The results indicated that overall performance of PE-g-MAH/PP/kaolin composite material had best performance in terms of tensile strength, impact strength and elongation at break, when the composites were prepared with PE containing 5% MAH and PP at the ratio of 1:1 in mass, then added with modified kaolin at 15%. The tensile strength, impact strength and elongation at break were 10.925 MPa, 40.6 kJ/m2 and 89.5% respectively. The non-flame property of the composite material first rapidly increased and then slowly decreased with the addition of kaolin. The optimum addition of kaolin was 15%. Physical blending of components was realized. In conclusion, kaolin of a proper amount enhances the non-flame property of PE/PP composite material and the addition of MAH improves the compatibility of PE, PP and kaolin. |
