EVA边角料/NR/胶粉复合发泡材料的制备及其性能
Preparation and Property of Composite Foam Materials of Poly(Ethylene Vinyl Acetate)Offcuts/Natural Rubber/Rubber Powders
摘要
Abstract
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,dicumyl 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.关键词
