| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
