增塑剂A和莱茵塑分AP在胎面胶中的应用对比

Comparison between plasticizer A and Aktiplast APapplied in tread compound

进行增塑剂A和莱茵塑分AP的组分分析并研究其在胎面胶中的应用效果。结果表明,增塑剂A中软脂酸含量较大,莱茵塑分AP中硬脂酸和油酸含量较大;莱茵塑分AP对胶料流动性和分散性改善效果优于增塑剂A;加入增塑剂A和莱茵塑分AP的胶料焦烧时间有所延长、硫化速度减慢,硫化胶的邵尔A型硬度和300%定伸应力略有提高,拉断伸长率稍有下降。

The composition of plasticizer A and Aktiplast AP was analyzed and their effectiveness in tread compound was investigated. The results showed that plasticizer A contained more palmicacid, and Aktiplast AP contained more stearic acid and oleic acid;in terms of improving compound flowability and dispersity,Aktiplast AP was better than plasticizer A;and the scorch time of compound extended and the curing rate decreased,and the Shore A hardness and modulus at 300% of vulcainzate increased a little, but the elongation at break somewhat decreased by adding plasticizer A or Aktiplast AP.
