| 摘 要： | 研究了甲基丙烯酸锌(ZDMA)、SiO,和炭黑N 550分别填充氢化丁腈橡胶(HNBR)的流动性、硫化特性、物理机械性能、耐老化性能、压缩永久变形及动态力学性能,表征了填料在HNBR混炼胶及硫化胶中的形态结构.结果表明,3种填料填充的HNBR混炼胶均属非牛顿流体,其中ZDMA填充HNBR混炼胶具有较好的流动性;经过二段硫化后.3种填料填充HNBR具有较佳的物理机械性能、耐老化性能和耐压缩性能;zDMA和SiO2,对HNBR的增强效果显著,但HNBR硫化胶的压缩永久变形偏高,N 550填充HNBR硫化胶的扯断伸长率和压缩永久变形较低;SiO2填充HNBR混炼胶和硫化胶的Payne效应较ZDMA、N 550填充HNBR混炼胶和硫化胶显著;N 550、SiO2种填料在HNBR混炼胶和硫化胶中均能达到纳米尺度,ZDMA在HNBR混炼胶中呈微米尺度,而在HNBR硫化胶中呈纳米尺度.

| Abstract: | The rheological properties,curing characteristics,mechanical properties,aging resistance,compression set and dynamic mechanical properties of hydrogenated nitrile rubber(HNBR) separately filled with zinc dimethacrylate(ZDMA),SiO2 and carbon black N 550 were studied.The morphological structure of fillers in HNBR compounds and vulcanizates were characterized.The results showed that all the HNBR compounds with 3 different fillers were non-Newtonian fluid,and compared with the compounds with N 550 and SiO2,the ... |
