环保型橡胶增塑剂在半钢子午线轮胎胎面胶中的应用

Application of Environmentally Friendly Rubber Plasticizer in the Tread Compound of Steel-belted Radial Tire

研究对比国产石油系环保型橡胶增塑剂HJA1824与进口环保芳烃油(TDAE)和残余芳烃抽提物(RAE)在半钢子午线轮胎胎面胶中的应用。结果表明:增塑剂HJA1824,TDAE和RAE的芳碳率(C_A)均较大(大于18%),环保性能均达到欧盟要求;3种增塑剂胎面胶的混炼工艺性能和硫化特性相当,增塑剂HJA1824胎面胶的耐压缩疲劳性能略好,滚动阻力略低,耐磨性能介于TDAE和RAE胎面胶之间。增塑剂HJA1824可作为绿色轮胎的优选原材料。

This study compared the domestic environmentally friendly petroleum-based rubber plasticizer HJA1824 with imported environmentally friendly aromatic oil（TDAE） and residual aromatic extract（RAE） in the tread compound of semi-steel radial tire. The experimental testing results showed that the aromatic carbon ratios（C_A） of all three plasticizers were greater than 18%,environmental protection meeting EU requirement. The tread compounds with those three plasticizers showed similar mixing properties and curing characteristics. The dynamic compression fatigue resistance of the tread compound with plasticizer HJA1824 was slightly better,the rolling resistance was a little lower,and the abrasion resistance was between the compounds with TDAE and RAE. It was concluded that plasticizer HJA1824 was a preferable choice in green tire.
