新型抗湿滑、抗老化硅烷偶联剂可以极大地促进"绿色轮胎"的发展。目前常用于提高轮胎性能的硅烷偶联剂多为多硫硅烷偶联剂，如二硫硅烷偶联剂（Si75）、四硫硅烷偶联剂（Si69）等，此类偶联剂在实际应用中大多存在多硫键容易断链、参与硫化反应从而容易烧焦造成抗老化性能差等缺点，并且其滚动阻力较低，抗湿滑性能也较差。为改善上述缺点，利用巯基乙酸和乙烯基三乙氧基硅烷偶联合成了一种新的单硫硅烷偶联剂2-乙酸基硫代-1-乙基三乙氧基硅烷，并对合成条件进行了探讨。

The development of "green tire" can be greatly promoted by the synthesis of new anti-wet and anti-aging silane coupling agents.At present, multi-sulfur silane coupling agents, such as disulfide silane coupling agent (Si75) and tetrathiosilane coupling agent (Si69), are the main varieties commonly used to improve tire performance.However, most of multi-sulfur silane coupling agents have the disadvantages in practical applications, including that multi-sulfide bonds are easy to break, the agents involve in vulcanization and are therefore easy to scorch, which results in poor aging resistance.Most of them can cause the tire to have low rolling resistance and poor wet skid resistance.To make up for these shortcomings, 2-acetate-thio-1-ethyl triethoxysilane, a new monothiosilane coupling agent, is synthesized by coupling mercaptoacetic acid with vinyltriethoxysilane, and the corresponding synthetic conditions are discussed.
