聚乙烯/炭黑型PTC材料的稳定性研究

Study on Stability of Polyethylene/Carbon Black Composites with Positive Temperature Coefficient Effect

通过加入抗氧剂、交联剂及相容剂 ,采用熔融共混后挤出成型制样 ,对聚乙烯 /炭黑体系正温度系数 (PTC)效应的稳定性进行了研究 ,为研究和开发高性能的聚合物PTC材料提供了经验。

Polyethylene/carbon black composite was extruded by melting blending with the incorporation of antioxidants,crosslinking agents and compatibilizing agents.Stability of positive temperature coefficient effect of polyethylene/carbon black system is studied.
