PLA/ABS增容改性研究
Research on Toughening Modification of PLA/ABS
摘要
Abstract
By utilizing four different types of typical compatibilizers and dicumyl peroxide(DCP),toughening modification was performed on the blend system of polylactic acid/acrylonitrile-butadiene-styrene copolymer(PLA/ABS).The compatibility and crystallization properties of the blend system were characterized and tested through mechanical property tests,scanning electron microscopy(SEM),and differential scanning calorimetry(DSC).The results showed that the addition of compatibilizers could form a better dispersed"sea-island"phase structure in the blend system,with the tensile strength and impact strength increasing by up to 18.23%and 21.98%,respectively,although the crystallization capability decreased.With the addition of both compatibilizers and DCP,the phase structure of the blend system transformed into coexisting"sea-island"and"sea-sea"phases,with the maximum increases in tensile strength and impact strength of 47.99%and 86.64%,respectively.The compatibilizers and DCP synergistically enhanced the toughening effect on the blend system and improved its crystallization capability.关键词
