PP/EPDM-g-MAH/CaCO3晶须复合材料的性能研究OACSTPCD
Mechanical Properties of PP/EPDM-g-MAH/CaCO3 Whisker Ternary Composite
采用高剪切应力和添加引发剂的复合引发方法制备了EPDM-g-MAH,将其单独或与CaCO3晶须协同改性PP.通过滴定分析、红外表征和熔体流动速率测定方法研究了175℃条件下螺杆转速对EPDM-g-MAH的熔体流动速率、接枝率的影响.探讨了EPDM-g-MAH和碳酸钙晶须用量对PP力学性能、热变形温度的影响.结果表明:二元共混材料PP/EPDM-g-MAH在弹性体用量为30 phr时缺口冲击强度为9.85 kJ/m2,是纯PP的1.97倍,热变形温…查看全部>>
The melting-grafting of maleic anhydride ( MAH ) onto ethylene-octene copolymer ( EPDM ) through adding a certain initiator and increasing the screw rotation speed were investigated,and the graft prod-ucts were used to improve the mechanical properties of polypropylene or with calcium carbonate. The grafting level and the melt flow rate were studied by titration analysis,FT-IR and determination of melt flow rate at 175 degrees centigrade. The mechanica…查看全部>>
