摘　　要：研究硅橡胶(VMQ)/乙烯丙烯酸酯橡胶(AEM)并用胶的性能和应用。结果表明:VMQ与AEM并用后,并用胶的门尼粘度适中,挤出工艺性能良好,力学性能、耐高低温性能、抗裂纹扩展性能以及热空气老化后与氟橡胶胶料的粘合性能较好,使用寿命较长,工作温度范围较宽;VMQ/AEM并用胶作为新材料可以应用于汽车进气系统高温段管路。The properties and applications of silicone rubber(VMQ)/ethylene acrylate rubber(AEM)blend were studied.The results showed that,after VMQ was blended with AEM,the Mooney viscosity of the blend was appropriate,the extrusion process performance was excellent,the mechanical properties,high and low temperature resistance,crack growth resistance and adhesive properties to fluororubber compounds after hot air aging were good,the service life was extended,and the operating temperature range was wider.VMQ/AEM blend could be used as a new material for the rubber hose in the high temperature section of the automobile air intake system.
