摘　　要：通过采用六次甲基四胺对腰果壳粉进行改性,并制备了腰果壳粉/聚氯乙烯(PVC)复合材料。研究改性前后腰果壳粉的用量对复合材料力学性能、耐水性和加工性能的影响,并用扫描电镜(SEM)观察了断面形貌。结果表明:随着不同腰果壳粉用量的增加,复合材料的拉伸强度、冲击强度、弯曲强度呈先上升后下降的趋势,当腰果壳粉用量为5～10份时最佳;添加质量分数为5%的六次甲基四胺改性腰果壳粉时,复合材料的物理力学性能、耐水性提高。The cashew nut shell flour was modified by hexamethylene tetramine（ C6H12N4 ） ,cashew nut shell flour/PVC composite were prepared. The effects of varieties content of cashew nut shell flour on mechanical properties, water proof and proceeding fluidity of cashew nut shell flour/PVC composite were investigated. The morphology structure of cashew nut shell flour/PVC composite was observed by SEM. Results showed that with increasing the amount of cashew nut shell flour or modified cashew nut shell flour,the properties of tensile strength ,impact strength,bending strength were increased at first and then decreased,composite with excellent properties was obtained by the content of cashew nut shell flour being 5 - 10 phr. When cashew nut shell flour was modified by C6H12N4 ,whose ratio was 5 % （ by mass） ,mechanical properties and water proof of composite were increased.
