PP/POE共混物力学性能研究

用双螺杆挤出机制备了聚丙(烯PP)/聚烯烃弹性(体POE)共混物,研究了POE用量对PP/POE共混物冲击性能、拉伸性能及弯曲性能的影响。结果表明:随着POE含量的增加,PP/POE共混物的冲击强度明显提高;拉伸强度及拉伸模量弯、曲强度及弯曲模量、断裂伸长率及断裂强度均减小。

Study on Mechanical Properties of PP/POE Blends

The PP/POE blends were prepared by using a twin-screw extruder,and effects of POE content on impact property,tensile property and flexural property of PP were studied. The results show that with the increase of POE content,the impact strength of PP/POE blends increases significantly; the tensile strength and tensile modulus,the flexural strength and flexural modulus,elongation at break and breaking strength of blends all decrease.
