| 中文摘要: |
| 研究低滚阻改性剂YG-G300（简称YG-G300）在航空轮胎胎圈护胶中的应用。结果表明：YG-G300可以增强炭黑与橡胶之间的作用力；在胎圈护胶中加入1～3份YG-G300，胶料的门尼粘度、模量和交联密度增大，焦烧时间略延长，硫化速度稍减慢，抗硫化返原性能显著提高；硫化胶的硬度、定伸应力、拉伸强度和耐磨性能提高，生热降低，耐高温性能提高；YG-G300用量为2份时，胶料的耐高温性能最优，同时综合物理性能较好。 |
| 英文摘要: |
| The application of low rolling resistance modifier YG-G300（abbreviated as YG-G300） in bead compound of aircraft tire was studied.The results showed that YG-G300 could enhance the force between carbon black and rubber.Adding 1～3 phr of YG-G300 to the bead compound，the Mooney viscosity，modulus and crosslinking density of the compound increased，the scorching time slightly prolonged，the curing rate slightly slowed down，and the anti-reversion property significantly improved.The hardness，modulus，tensile strength and wear resistance of the vulcanizate were improved，the heat build-up was reduced，and the high temperature resistance was improved.When the dosage of YG-G300 was 2 phr，the high temperature resistance of the compound was the best，and the comprehensive physical properties were good. |
