摘　　要： 以自制的乙烯-醋酸乙烯酯接枝马来酸酐（EVA-g-MAH）为相容剂，通过直接添加法和母粒添加法两种方式制备了EVA／硅酮粉复合材料。研究了硅酮粉和EVA-g—MAH的添加对该复合材料力学、热学以及加工性能的影响。结果表明：硅酮粉的添加改瞢了EVA材料的力学性能和热稳定性能，其最佳用量为4．0份，其中采用母粒添加法得到的复合材料性能更佳；相容剂EVA-g-MAH的引入对EVA／硅酮粉复合体系有一定的增容效果。当EVA-g—MAH用量为8．0-12份时，其对复合体系的增容效果最明显；另外。适量硅酮粉的添加还可改善复合材料的加工流动性。 The ethylene-vinyl acetate copolymer （EVA）/silicone powder composites were prepared by taking the self-made maleic anhydride graft ethylene-vinyl acetate （EVA-g-MAH） as the compatibilizer, and the silicone powder was added directly or in the form of masterbatch. The effects of silicone powder and EVA-g-MAH contents on mechanical, thermal and rheological properties of the EVA composites were studied. The results show that： the addition of silicone powder improves the thermal and mechanical properties of the EVA composites, the best dosage of silicone powder is 4 phr, and the composite system shows the better properties with the addition of silicone masterbatch. The compatibility of the EVA/silicone powder composite is improved by adding EVA-g-MAH, and the optimal addition amount of the compatibilizer is 8.0-12 phr. Moreover, the addition of silicone powder aslo can improve the rheological properties of the composite system.
