摘要
采用L9(34)正交实验方法,研究了弹性体乙烯-辛烯共聚物(8003树脂)、增容剂乙烯-丙烯酸共聚物(EAA)、滑石粉及增塑剂甘油对淀粉/乙烯-醋酸乙烯酯(EVA)复合发泡鞋底材料力学性能的影响,并通过X射线衍射(XRD)和扫描电镜(SEM)表征了共混物的结构。结果表明,滑石粉和8003树脂对共混物的拉伸强度、延伸率及回弹性有显著的影响,当8003树脂为20phr、EAA为30phr、滑石粉为0phr、甘油为8phr时,共混物的综合力学性能最好。XRD和SEM分析表明,EAA的加入能大大增加淀粉和EVA的相容性,达到增容的效果。
Through the L9 （34） orthogonal experiment, the effects of ethylene-octene copolymer（8003 resign）as elastomer, ethylene acrylic acid copolymer （EAA）as solubilizer, talc and glycerin as plasticizer on the mechanical properties of starch/ethylene-vinyl acetate（EVA） composite foamed materials, were studied. The structure of starch/ EVA composite foamed materials was characterized by X-ray diffraction（XRD） and scanning electron microscopy （SEM）. The results show that talc and 8003 resin have the remarkable influence on the tensile strength, elongation and elastic property of the composite foamed materials. The starch/EVA composite foamed materials have the best comprehensive mechanical properties when being blended with 20 phr 8003 resin, 30 phr EAA, 0 phr talc and 8 phr glycerin. The results of XRD and SEM show that the compatibility of starch and EVA can be highly improved with the addition of EAA.
