    • 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.
    • 公开了包含通过水解烯基烷氧基硅烷化合物而获得的烯基硅烷醇表面改性的无机粒子的功能性增强填料及其制备方法。 由于所公开的功能性增强填料具有双键的官能团,因此对苯乙烯 - 丁二烯橡胶和硫具有良好的反应性。 因此,当在橡胶制造中用作功能性增强填料时,其可以通过调节硫的添加量来改善物理性能,而不需要额外使用偶联剂。 此外,由于优异的水解反应性,可以解决醇的问题,并且可以制备具有长焦烧时间的橡胶混合物。 特别地,当本发明的功能性增强填料用于轮胎的制造中时,可以预期模量,拉伸强度,旋转阻力和湿牵引性能的提高。
