摘　　要：研制了民航飞机机轮橡胶密封圈混炼胶料,物理机械性能满足GJB 5258—2003标准要求。与现用胶料相比,拉断伸长率提高约20%,150℃×22 h YH-10液压油中压缩永久变形率降低约60%;同一辊胶料历经10个月,先后4次重复热炼、挤出,胶料的物理机械性能几乎没有变化,且加工工艺性能良好;采用实验室加速老化方法,预测硫化制品寿命提高近50%。Research and development of the rubber compounds of rubber sealing rings for civil aircraft wheel,the physical and mechanical properties meet the requirements of GJB 5258-2003 standard.Compared with the current rubber compounds,the elongation at break is increased by about 20%;the permanent compression set value is reduced about 60%in YH-10 hydraulic oil at 150℃×22 h;the same roll of rubber compounds has been rolled pressing and extruded for 4 times in 10 months,the physical and mechanical properties of the rubber compounds are almost unchanged,and the processing performance is good;the accelerated aging method is used to predict the working time of the vulcanized rubber,it was increased by nearly 50%.
