摘　　要：研究3种功能性树脂(C_5树脂、TL100树脂及HB103树脂)在低用量(5份)和高用量(26份)下对轮胎胎面胶性能的影响。结果表明:添加3种树脂的胶料门尼粘度均减小,硫化速度减慢,C_5树脂在低用量下对胶料的增塑效果不明显,在高用量下使胶料的门尼粘度大幅降低;HB103树脂在低用量下胶料的硬度较低,C_5树脂在高用量下胶料的硬度较低;添加3种树脂的胶料回弹值均减小,C_5树脂和TL100树脂在高用量下胶料的回弹值明显减小;添加3种树脂的胶料定伸应力、拉伸强度和拉断伸长率差异较大;添加3种树脂的胶料玻璃化温度(T_g)和抗湿滑性能提高,HB103树脂胶料和TL100树脂胶料具有较好的抗湿滑性能和较低的滚动阻力,TL100树脂适用于低树脂用量胶料配方,HB103树脂适用于高树脂用量胶料配方。The effects of three functional resins（C5 resin,TL100 resin and HB103 resin） on the properties of tire tread compound were studied at different addition levels,i.e.low addition level of 5 phr and high addition level of 26 phr.The results showed that the Mooney viscosity of the compound decreased and the vulcanization rate was slowed down with the functional resins.The plasticizing effect of C5 resin on the compound was not obvious at low addition level,and the Mooney viscosity of the compound with C5 resin was greatly reduced under high addition level.The hardness of the compound with low addition level of HB103 resin or with high addition level of C5 resin was lower. The rebound resilience of the compound with the functional resins decreased,and the rebound resilience of the compound with high addition level of C5 resin or TL100 resin was greatly reduced.It was found that the modulus,tensile stress and elongation at break of the compounds showed significant difference when different functional resin was added.The glass transition temperature and wet skid resistance were improved by adding the functional resins,and the compound with HB103 resin or TL100 resin possessed good wet skid resistance and low rolling resistance.TL100 resin was suitable for use in the compound with low addition level of functional resin and HB103 resin was suitable for formulation with high addition level of functional resin.
