| 中文摘要: |
| 试验研究防焦剂CTP减量对轿车子午线轮胎胎圈护胶喷霜的影响。结果表明，随着防焦剂CTP用量的增大，胶料的焦烧时间延长，硫化速率和物理性能变化不大；防焦剂CTP用量超过0.3份时，硫化试样停放一定时间后表面产生喷霜现象；防焦剂CTP用量为0.25～0.3份时，胶料焦烧性能和加工性能满足挤出工艺生产要求，挤出性能良好，挤出半成品表面无喷霜现象产生。 |
| 英文摘要: |
| The influence of anti-scorching agent CTP on blooming from bead chafer of PCR tire was experimentally investigated.The results showed that the scorching time of bead chafer compound extended without any adverse effect on curing rate and physical properties as the addition level of CTP increased；the blooming occured on the surface of cured sample after conditioning for a certain time when the addition level of CTP exceeded 0.3 phr；and a bead chafer compound with desired scorching life and extrudability was obtained and the blooming didn′t occur on the surface of extrudate when 0.25～0.3 phr CTP was used. |
