LDPE-g-MAH对LDPE/PVDC共混体系性能的影响
Effect of LDPE-g-MAH on Properties of LDPE/PVDC Blend
摘要
Abstract
Taking LDPE as matrix material, PVDC as dispersed phase, LDPE-g-MAH as compatibilizer, the LDPE/PVDC/LDPE-g-MAH blend was prepared by extrusion and injection molding. The mechanical properties, barrier properties, crystallization properties and fracture surface micro-morphology of the blend were studied. The results show that the melting temperature of LDPE/PVDC blend decreased by 1.79℃ with the addition of 25％ PVDC, the oil absorption rate decreased by 9.66％,and the mechanical properties decreased markedly. The adhesive strength between LDPE and PVDC was enhanced with the addition of LDPE-g-MAH, which improved the compatibility of the blend, besides the crystallization temperature and crystallinity decreased slightly, Compared with pure LDPE, after the addition of 3％ LDPE-g-MAH, the elongation at break of the blend increased by 11.63％, the notched impact strength increased by 13.35％, the oil absorption rate decreased by16.29％, and the flexibility and barrier properties of the blend increased obviously.关键词
