| 中文摘要: |
| 介绍尺寸稳定型（DSP）聚酯帘布压延工艺及其在子午线轮胎中的应用。DSP聚酯帘布合理的压延工艺条件为压延方式 贴胶；压延速度 25～35 m·min-1；主机温控：一、四辊辊温 75～80 ℃，二、三辊辊温 80～85 ℃。采用DSP聚酯帘布生产轮胎在高温硫化时可取消后充气工艺，在保持轮胎胎体强度基本不变的条件下可减小胎体帘布层数。 |
| 英文摘要: |
| The calendering technique of DSP and its application in radial tire are described.The proposed calendering technology is as follows：calendering type coating；calendering speed 25～35 m·min-1；temperature of rolls 1 and 4 75～80 ℃，temperature of rolls 2 and 3 80～85 ℃.The post cure of the tire cured at high temperature can be eliminated by using DSP cord，and the carcass ply number can also be reduced while the strength of tire body changes little. |
