摘要
Abstract
Blends of polypropylene (PP) with devulcanization ground tire rubber (DGTR) were prepared by melt blending,and their impact performance,rheological properties and crystallization behaviors was investigated.Furthermore,reaction mechanisms between PP and DGTR were analyzed.The blend containing 15 wt ％ DGTR achieved maximum Izod impact strength of 8.5 kJ/m2,which was increased by 49.1％ compared with that of pure PP.Based on the analysis of X-ray powder diffraction patterns,there are some β-type crystals of PP in the blends,and the amount of β-type crystals reached 11.2 ％ for the blend containing 30 wt ％ of DGTR.The change in morphology of the powder caused by desulphurization,which promotes the formation of β-type crystals.关键词
