| 中文摘要: |
| 研究4种相对分子质量和玻璃化温度相近的溶聚丁苯橡胶牌号2466，F2743，F2150A和HPR850在全钢子午线轮胎胎面胶中的应用。结果表明：4种胶料的门尼粘度、硫化特性和填料分散性基本相当；F2743硫化胶的定伸应力和拉伸强度略低，F2150A硫化胶的常温回弹值最大，添加均匀剂的HPR850硫化胶的回弹值减小，耐磨性能下降；2466与天然橡胶的相容性最好，2466硫化胶的生热最低，F2743和HPR850硫化胶的抗湿滑性能更优，但生热明显增加。 |
| 英文摘要: |
| The application of four solution polymerized styrene butadiene rubber，product grade 2466，F2743，F2150A and HPR850 with similar relative molecular weight and glass transition temperature in the tread compound of all-steel radial tire was studied.The results showed that the Mooney viscosity，vulcanization characteristics and filler dispersion of SSBR compounds were basically equivalent.The modulus stress and tensile strength of F2743 vulcanizate were slightly lower，while the room temperature rebound value of 2150A vulcanizate was the maximum.HPR850 vulcanizate with a homogenizer had smaller rebound value and worse wear resistance.The compatibility of 2466 and natural rubber was the best，the heat build-up of 2466 vulcanizate was the lowest，and the wet-skid resistance of F2743 and HPR850 vulcanizate were better，but the heat build-up significantly increased. |
