Provided is a method capable of efficiently producing a modified diene-based rubber, and a rubber composition and a tire with excellent low hysteresis loss property, durability, etc. The method for producing a modified diene-based rubber of this disclosure comprises: performing modification by adding a modifier into a solution of a diene-based rubber as raw material obtained by dissolving a diene-based rubber as raw material in a solvent, and removing the solvent and reacting the modifier with the diene-based rubber as raw material while exerting a mechanical shear force, to thereby generate a modified diene-based rubber. The rubber composition of this disclosure uses a modified diene-based rubber produced with the method for producing a modified diene-based rubber of this disclosure. The tire of this disclosure uses the rubber composition of this disclosure.
本发明提供了一种能够高效生产改性二烯基橡胶的方法,以及一种具有优异的低滞后损失特性和耐久性等的橡胶组合物和轮胎。本公开的改性二烯基橡胶的生产方法包括:通过向将二烯基橡胶作为原料溶解在溶剂中得到的二烯基橡胶溶液中加入改性剂进行改性,然后除去溶剂并在施加机械剪切力的同时使改性剂与二烯基橡胶作为原料发生反应,从而生成改性二烯基橡胶。本公开的橡胶组合物使用本公开的改性二烯基橡胶生产方法生产的改性二烯基橡胶。本公开的轮胎使用本公开的橡胶组合物。
