Disclosed are a functional reinforcing filler including inorganic particles surface-modified with an alkenylsilanol obtained by hydrolyzing an alkenylalkoxysilane compound, and a method for preparing the same. Since the disclosed functional reinforcing filler has a functional group having a double bond, it has good reactivity for styrene-butadiene rubber and sulfur. Thus, when used as a functional reinforcing filler in the manufacture of rubber, it allows improvement of physical properties through adjustment of the addition amount of sulfur without additional use of the coupling agent. In addition, because of superior hydrolysis reactivity, the problem of alcohol can be solved and a rubber mixture with long scorch time can be prepared. In particular, when the functional reinforcing filler of the present invention is used in the manufacture of tires, improvement in modulus, tensile strength, rotational resistance and wet traction performance can be expected.
本发明公开了一种功能性增强填料,其中包括经过烯基硅醇表面修饰的无机颗粒,该烯基硅醇是通过水解烯基烷氧基硅烷化合物得到的,并且公开了其制备方法。由于所公开的功能性增强填料具有具有双键的功能性基团,因此对于苯乙烯-丁二烯橡胶和硫具有良好的反应性。因此,在橡胶制造中使用作为功能性增强填料时,可以通过调整硫的添加量来改善物理性能,而无需额外使用偶联剂。此外,由于其优异的水解反应性,可以解决醇的问题,并制备具有长烧伤时间的橡胶混合物。特别是,当本发明的功能性增强填料用于轮胎制造时,可以预期提高模量、拉伸强度、旋转阻力和湿地牵引性能。
