环保型抗湿滑橡胶软化剂TY-18在乘用轮胎胎冠胶中的应用

Application of Environmentally Friendly Anti-slip Rubber Softener TY-18 in the Tire Crown Compound of Passenger Car Tire

介绍抗湿滑橡胶软化剂TY-18在乘用轮胎胎冠胶中的应用。结果表明:与环保型芳烃油(TDAE)胶料和环保型环烷油(NAP)胶料相比,抗湿滑橡胶软化剂TY-18胶料的玻璃化温度较低,0℃时的tanδ值较大,60℃时的tanδ值较小,抗湿滑橡胶软化剂TY-18胶料具有良好的抗湿滑性能、较低的滚动阻力及优良的耐磨性能,老化前后的其它物理性能与TDAE和环保型NAP胶料基本相同;抗湿滑橡胶软化剂TY-18的价格和密度较低,倾点和粘度远远小于TDAE,用其生产的胶料密度较小,可有效降低轮胎制造成本,大幅降低输送设备的能源消耗;抗湿滑橡胶软化剂TY-18兼具TDAE与NAP的性能优势,可以替代TDAE和NAP用于胎冠胶。

The application of anti-slip rubber softener TY-18 in the tire crown of the passenger car tire was investigated. Compared with the compounds with environmentally friendly aromatic oil （TDAE） and environmentally friendly naphthenic oil （NAP）, the compound with TY-18 possessed lower glass transition temperature, higher tanδvalue at 0℃and lower tanδvalue at 60℃. The vulcanizates with TY-18 had excellent wet skid resistance, low rolling resistance, and excellent wear resistance. The physical properties of the vulcanizates before and after aging were similar to the vulcanizates with TDAE and NAP. The cost and density of TY-18 were low, and the pour point and viscosity were much lower than TDAE. Therefore, by using TY-18, the density of the compound and the cost of tire could be reduced, and the energy consumption for transportation was signiifcantly reduced.
