Silica-reinforced rubber composition and tire component

The invention discloses a silica reinforced rubber composition and a tire component. The present invention relates to improved tire tread compositions, such as silica-filled tire tread compositions, and tires using the same. In one embodiment, there is provided a tire tread comprising a diene-based elastomer, a reinforcing filler comprising an inorganic filler (e.g., silica), and a plurality of silane compounds, the silane compound includes a bis (dialkyl alkoxysilyl-alkyl) polysulfide coupling agent and at least one alkoxysilane compound selected from the group consisting of a hydrophobized bis (trialkoxy) silane coupling agent and a hydrophobized mono (trialkoxy) silane dispersant. 本发明公开了二氧化硅增强的橡胶组合物和轮胎组件。本发明涉及改进的轮胎胎面组合物，例如二氧化硅填充的轮胎胎面组合物，以及使用其的轮胎。在一个实施方案中，提供了一种轮胎胎面，其包含基于二烯的弹性体、包括无机填料(例如二氧化硅)的增强填料、和多种硅烷化合物，所述硅烷化合物包括双(二烷基烷氧基甲硅烷基-烷基)多硫化物偶联剂和选自疏水化双(三烷氧基)硅烷偶联剂和疏水化单(三烷氧基)硅烷分散剂的至少一种烷氧基硅烷化合物。
