摘　　要：研究新型高活性间苯二酚-甲醛树脂(间-甲树脂)SL3020LFR在载重轮胎胎体帘布胶中的应用。结果表明:与非间-甲树脂胶料相比,高活性间-甲树脂SL3020LFR胶料的硫化活性较高,其加工性能、老化前后的拉伸性能和粘合性能均符合载重轮胎胎体帘布胶的性能要求,尤其是胶料具有低动态滞后损失和低动态生热特性,将其用于载重轮胎胎体帘布胶中能够降低轮胎的滚动阻力和内部生热,提高耐久性能和翻新价值。The application of new type highly active resorcinol formaldehyde resin SL3020LFR in the carcass ply compound of TBR tire was studied.The results showed that,compared with non-resorcinol formaldehyde resins compound,the vulcanization activity of the compound with SL3020LFR was higher,and the processability,tensile property before and after aging,and adhesion property were all in line with the property requirements of TBR tire carcass ply compound.Especially,the compound had low dynamic hysteresis loss and low dynamic heat generation property.Therefore,it could be used in TBR tire carcass ply compound to reduce tire rolling resistance and internal heat generation to improve durability and retreading value.
