Abstract

The methoxy-type silane coupling agents were synthesized via the modification of the hydrolyzable group and characterized to investigate the change in properties of silica/rubber composites based on the different silane coupling agent structures and the masterbatch fabrication methods. The prepared methoxy-type silane coupling agents exhibited higher reactivity towards hydrolysis compared to the conventional ethoxy-type one which led to the superior silanization to the silica filler surface modified for the reinforcement of styrene-butadiene rubber. The silica/rubber composites based on these methoxy-type silane coupling agents had the characteristics of more developed vulcanization and mechanical properties when fabricated as masterbatch products for tread materials of automobile tire surfaces. In particular, the dimethoxy-type silane coupling agent showed more enhanced rubber composite properties than the trimethoxy-type one, and the environmentally friendly wet masterbatch fabrication process was successfully optimized. The reactivity of the synthesized silane coupling agents toward hydrolysis was investigated by FITR spectroscopic analysis, and the mechanical properties of the prepared silica-reinforced rubber polymers were characterized using a moving die rheometer and a universal testing machine.

摘要

通过对可水解基团进行改性合成了甲氧基型硅烷偶联剂,并对其进行了表征,以研究基于不同硅烷偶联剂结构和母粒制备方法的二氧化硅/橡胶复合材料性能的变化。与传统的乙氧基型硅烷偶联剂相比,所制备的甲氧基型硅烷偶联剂对水解表现出更高的反应活性,这导致对用于增强丁苯橡胶的二氧化硅填料表面的硅烷化效果更佳。当将基于这些甲氧基型硅烷偶联剂的二氧化硅/橡胶复合材料制成汽车轮胎表面胎面材料的母粒产品时,它们具有更发达的硫化特性和机械性能。特别是,二甲氧基型硅烷偶联剂比三甲氧基型硅烷偶联剂表现出更优异的橡胶复合材料性能,并且成功优化了环保型湿法母粒制备工艺。通过傅里叶变换红外光谱(FITR)分析研究了合成的硅烷偶联剂对水解的反应活性,并使用动态硫化仪和万能试验机表征了所制备的二氧化硅增强橡胶聚合物的机械性能。
