PP/EVAL/PP-g-MAH动态硫化体系的结构与性能研究
Study on the Structure and Property of PP/EVAL/PP-g-MAH Dynamically Vulcanized Blends
摘要
Abstract
The mechanical property, morphology, crystallography and dynamic mechanical property of propylene/saponified ethylene-vinyl acetate copolymer/maleic anhydride graft polypropylene (PP/EVAL/PP-g-MAH) dynamically vulcanized blends. The results show that: the mechanical properties and mold flow rate (MFR) of PP/EVAL dynamically vulcanized blend improve with the addition of PP-g-MHA significantly. The impact strength of PP/EVAL/PP-g-MAH (80/20/8) dynamically vulcanized blend increases by 179.6% compared with the PP/EVAL(80/20) dynamically vulcanized blend, reaches to 74.1 kJ/m2, and the MFR is 13.4 g/10min. The dispersion effect of the disperse phase and the compatibility between PP phase and EVAL phase improves with the addition of PP-g-MAH, and the formation of α crystallization and β crystallization of PP in the PP/EVAL dynamically vulcanized blend promotes. Tg of PP component of the PP/EVAL dynamically vulcanized blend shifts to lower tempetature with the addition of PP-g-MAH.关键词
