摘　　要：以废弃工业乙烯-乙酸乙烯酯(EVA)泡沫边角料、天然橡胶(NR)和废旧胶粉等为原料,通过共混模压制备EVA边角料/NR/胶粉复合发泡材料。研究了交联剂、发泡剂等助剂的种类与含量对EVA边角料/NR/胶粉复合发泡材料的发泡性能和力学性能的影响。结果表明,偶氮二甲酰胺、过氧化二异丙苯、N550炭黑、轻质碳酸钙含量分别为4 phr(每百克份数)、0.8 phr、5 phr、10 phr时,复合发泡材料的发泡质量及力学性能较好。差示扫描量热、X射线衍射测试数据表明,在复合发泡材料体系中,EVA和NR的相容性良好,且填充胶粉后,共混体系的结晶能力下降。The composite foams of poly （ethylene vinyl acetate） （EVA）/natural rubber （NR）/rubber powders were prepared by blending and compression molding method using the scraps of industrial EVA foams, NR and waste rubber powders as raw materials. The effects of the content of rubber powders and the additives, such as the cross-linking agent, blowing agent and fillers, on the property of the composite foams were investigated. Experimental data indicated that the foaming quality and mechanical properties were good when the contents of azodicarbonamide, dieumyl peroxide, carbon black N550 and light calcium carbonate were 4 phr, 0.8 phr, 5 phr and 10 phr, respectively. The microstructure and thermal property of composite foams of EVA/NR/rubber powders were measured by the differential scanning calorimetry and X-ray diffraction, confirming that EVA had good compatibility with NR in the composite foams. Besides, the crystallization of composite foams decreased after addition of rubber powders.
