丁苯橡胶如今已广泛应用于汽车工业,但由于传统乳液聚合丁苯橡胶的滞后损失和滚动阻力大,因此,有必要使用性能更佳的溶液聚合丁苯橡胶替代乳聚丁苯橡胶制备胎面胶。为进一步改善溶聚丁苯橡胶与填料间相容性从而提升胎面胶性能,当前,通过对溶聚丁苯橡胶链端进行官能化改性是改善溶聚丁苯与填料相容性的常见方法,本文介绍了几种官能化改性溶聚丁苯橡胶的方法。
Styrene-butadiene rubber is now widely used in the automotive industry, but because of the large hysteresis loss and rolling resistance of conventional emulsion-polymerized styrene-butadiene rubber, it is necessary to use better solution-polymerized styrene-butadiene rubber instead of latex-styrene-butadiene rubber for the production of treads glue. In order to further improve the compatibility between the soluble styrene-butadiene rubber and the filler to improve the performance of the tread rubber, it is common to improve the compatibility of the soluble styrene-butadiene rubber with the filler by functionalizing the chain ends of the soluble styrene- Method, this article describes several functionalized modified solution styrene-butadiene rubber method.
