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。The application of low rolling resistance modifier YG-G300(abbreviated as YG-G300)in the bead compound of aircraft tires was studied.The results showed that YG-G300 could enhance the force between carbon black and rubber.Adding 1~3 phr YG-G300 to the bead compound,the Mooney viscosity,modulus and crosslinking density of the compound increased,the scorching time was slightly prolonged,the curing rate was slightly slowed down,and the anti-reversion property was 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.
