摘要
采用机械共混的方法研究了人造湿磨法云母粉代替部分炭黑用于丁腈橡胶的补强效果。结果表明:在研究范围内,人造湿磨法云母粉对丁腈橡胶的硫化特性和耐油性能没有明显的影响,对硫化胶有一定的补强作用,能提高其曲挠性能和耐热老化性能,德墨西亚曲挠次数从0.8万次可增加至4.6万次,老化后拉伸强度保持率从86%可提高到99.1%,但耐磨性能和高温压缩永久变形性能稍微下降。
The application of synthetic wet-grinding mica powder replacing partial carbon black to NBR was investigated by chemical blending. The results showed that the curing behavior and oil resistance of NBR were effected a litte by mica powder. Mica powder acted as reinforcing agent in NBR. The flex performance and thermal-oxide ageing property of NBR was improved by adding mica powder. But the wear resistance and compression set at 100℃ acted adversely by adding mica powder.
