摘　　要：对汽车用空气弹簧橡胶气囊胶料的配方进行研究。结果表明:与天然橡胶(NR)/氯丁橡胶(CR)并用胶相比,CR胶料的300%定伸应力和拉伸强度增大,耐热老化性能和耐疲劳性能提高;在空气弹簧橡胶气囊的试制中,NR/CR并用胶采用传统压延工艺制备,预期生产出的橡胶气囊壁厚约为2 mm,CR胶料采用层芯喷注工艺制备,预期生产出的橡胶气囊壁厚约为1.6 mm。The formulation of the rubber bladder compounds for automotive air springs was studied.The results showed that compared with the natural rubber(NR)/chloroprene rubber(CR)blend,the tensile stress at 300%and tensile strength of the CR compound increased,the heat aging resistance and fatigue resistance were improved.In the trial production of the rubber bladder for air spring,the NR/CR blend was prepared by the traditional calendering process,the expected wall thickness of the rubber bladder produced was about 2 mm,while CR compound utilized a layer core injection process,and the expected wall thickness of the rubber bladder produced was about 1.6 mm.
