不同硫化体系对丁腈橡胶压缩疲劳温升的影响

Influence of different vnlcanization systems on the temperature rising of NBR compression flexometer testing

研究了有效硫化体系、半有效硫化体系、普通硫化体系、过氧化物硫化体系对丁腈橡胶压缩疲劳温升的影响,结果表明:在试验条件下,过氧化物、半有效硫化体系的压缩疲劳温升较低,而有效硫化体系的压缩疲劳温升较高,普通硫化体系的压缩疲劳温升居中。

This article discusses the influence on NBR temperature rising in compression flexometer testing, between the different vulcanization systems which are efficient, half-efficient, ordinary and peroxide. The results show that under the given testing condition, temperature rising in peroxide and half-efficient vulcanization system is lower, but in efficient vulcanization system, it is higher. And the result in ordinary vulcanization system is between them.
