研究了炭黑及白炭黑对胺类硫化体系硫化的AEM橡胶的补强作用,并探讨了炭黑和白炭黑种类及用量对AEM硫化胶力学性能的影响。结果表明,炭黑用量为40份时,拉伸强度和撕裂强度均最佳;炭黑N330,N550,N660和N774对AEM的补强作用分别为具有较好力学强度、较好压缩永久变形、较好力学性能均衡性和较差补强效果;白炭黑对AEM的补强效果较好。
The reinforcing effect of carbon black and white carbon black on the vulcanized AEM rubber of amine vulcanization system was studied. The effects of the type and amount of carbon black and white carbon on the mechanical properties of AEM vulcanizate were also discussed. The results show that the tensile strength and tear strength are the best when the amount of carbon black is 40 parts. The reinforcing effect of carbon black N330, N550, N660 and N774 on AEM are respectively better mechanical strength, better compression set , Good balance of mechanical properties and poor reinforcing effect; silica AEM reinforcing effect is better.
