Influence of Clay, Silicate and Carbon Black on the Environmental Resistance Properties of Hard Rubber

摘要

The effects of clay, silicate, and carbon black on the environmental resistance properties of hard rubber were investigated in this study. A laboratory electrolytic cleaning tank immersion test was conducted to evaluate the environmental resistance ability of all compositions. The experimental results showed that carbon black had the best hardness and resistivity stability after the immersion test. The optimum carbon black content in clay/carbon black-filled hard rubber sample is 45 phr when total filler content is either 105 or 120 phr. The silicate/carbon black-filled hard rubber samples in this study cannot pass the electrolytic cleaning tank immersion test.
