A silane based additive, rubber formulations including the additive and tires having tread portions made with the additive, together with methods of forming those products, are provided. Uncured rubber formulations in accordance with preferred embodiments of the invention comprise (1) a rubbery primary polymer or polymer blend, such as natural rubber and/or synthetic rubber; (2) reinforcing silica filler; (3) a network forming monomer or polymer, especially a thermosetting network forming moiety, for forming a secondary polymeric network; and (4) a silane containing one or more moieties of the aforementioned network forming polymer. In particular networks which can be generated in-situ are preferred. The cured rubber formulation should comprise the silica, having the secondary polymer network coupled thereto, within the rubber matrix, and not directly to the rubber chains via sulfidic linkages.
提供基于硅烷的添加剂、包含所述添加剂的橡胶配方和具有用所述添加剂制成的胎面部分的轮胎、以及形成那些产品的方法。根据本发明优选实施方式的未固化的橡胶配方包括(1)橡胶状主聚合物或聚合物共混物,例如天然橡胶和/或合成橡胶;(2)二氧化硅增强填料;(3)网络形成用单体或聚合物、尤其是热固性网络形成用部分,其用于形成辅助聚合物网络;和(4)含有上述网络形成用聚合物的一个或多个部分的硅烷。特别地,优选可原位产生的网络。固化的橡胶配方应当包括在橡胶基质内的如下二氧化硅:其具有偶联至其的辅助聚合物网络,并且该辅助聚合物网络不是经由硫键直接偶联至橡胶链。
