摘要

采用熔融共混的方法制备了辐射灭菌的聚丙烯/乙烯-丙二烯单体(PP/EPDM)二元共混物，并对共混物的力学性能进行了研究。分别以80:20、60:40、50:50、40:60和20:80的比例制备了PP/EPDM二元共混物。然后使用热压机和冷压机压缩二元共混物12分钟，并切割成1mm, 3mm和6mm厚度进行拉伸试验，冲击试验，硬度试验和傅里叶变换红外光谱分析。结果表明，EPDM含量高的二元共混物比EPDM含量低的二元共混物具有更强的弹性和更好的吸能性能。当引入100kGy辐射剂量时，二元共混物的杨氏模量表现较好，分子内形成交联。在PP/EPDM二元共混物中，20:80的PP/EPDM共混物的物理力学性能最好。这种二元混合物适用于医疗器械。

Physico-Mechanical Properties Polypropylene/Ethylene-Propylene Diene Monomer (PP/EPDM) Binary Blends

This study was to develop a radiation sterilized polypropylene/ethylene-propylene diene monomer (PP/EPDM) binary blends using melt blending and the mechanical properties of the blends were studied. The PP/EPDM binary blends were prepared in the ratios of 80:20, 60:40, 50:50, 40:60 and 20:80. The binary blends were then compressed for 12 minutes using the Hot and Cold Press machine and were cut into 1mm, 3mm and 6mm thickness for tensile test, impact test, hardness test and Fourier Transform Infrared Spectroscopy analysis. The results showed that higher EPDM content binary blends were more elastic and had better energy absorption compared to lower EPDM ratio binary blends. With the introduction of 100kGy radiation dose, the binary blends performed better in Young modulus with crosslinking formed within the molecules. Among the PP/EPDM binary blends, 20:80 PP/EPDM blends performed the best in both physical and mechanical properties. This binary blend was suitable for medical devices.
