研究了白炭黑175Gr分别与4种炭黑并用对轮胎胎面胶加工性能、物理机械性能和动态物理机械性能的影响。研究表明,随着炭黑粒径的增大和结构度的提高,白炭黑175Gr/炭黑填充的胶料正硫化时间都缩短;白炭黑175Gr/炭黑N234并用时,其胶料拉伸强度和拉断伸长率都最高;白炭黑175Gr分别与炭黑N220和炭黑N550并用时,两种胶料的回弹性和压缩疲劳性都较好;白炭黑175Gr/炭黑N220并用后,其胶料的Payne效应较小,滞后损耗因子最低。
The effects of the combination of 175Gr silica and four carbon blacks on the processing performance, physical mechanical properties and dynamic physical-mechanical properties of tire tread rubber were studied. The results show that with the increase of the particle size and the increase of the structure, the vulcanization time of silica gel filled with 175Gr / carbon black is shortened. When the silica gel 175Gr / carbon black N234 is used together, Strength and elongation at break are the highest; when the black carbon black 175Gr and carbon black N220 and carbon black N550, respectively, the two rubber compounds have good resilience and compression fatigue properties; white carbon black 175Gr / carbon black N220 The Payne effect of the rubber compound is smaller and the hysteresis loss factor is the lowest.
