以乙烯-醋酸乙烯共聚物( EVA)、三元乙丙橡胶( EPDM)为主要原料，制备出一种共混改性耐高温EVA复合材料。通过红外光谱、力学性能、热重分析、抗老化实验、扫描电镜等性能研究。实验结果表明：以EVA/EPDM作为复合基体，当m( EVA)∶m( EPDM)=9∶1时，在90℃范围72 h内具有良好的耐热性能，可用于传统眼镜生产用密封圈。

Using ethylene-vinyl acetate copolymer ( EVA ) , ethylene propylene diene monomer ( EPDM ) as the main raw materials, a blend of modified high temperature EVA composites were prepared. By infrared spectrosco-py, mechanical properties, thermal gravimetric analysis , aging experiments, scanning electron microscopy study of the performance. The results showed that:EVA / EPDM as the composite matrix , when m( EVA)∶m( EPDM) =9∶1 and in the range of 90℃, the composites have good heat resistance, which effectively improve the production of tra-ditional optical ring.
