A method for lowering the dynamic-to-static modulus ratio of vulcanized rubber, the method comprising a first step of kneading a rubber component, a filler and a compound represented by formula (I) or a salt thereof, a second step of kneading the kneaded mixture obtained in the first step, a sulfur component and a vulcanization accelerator, and a third step of thermally treating the kneaded mixture obtained in the second step, in formula (I), n represents an integer of 0 to 10. The compound represented by formula (I) or a salt thereof is preferably S-(3-aminopropyl)thiosulfuric acid or a salt thereof.
一种降低硫化橡胶动态与静态模量比的方法,该方法包括第一步:将橡胶组分、填料和化合物(I)或其盐混合揉捏;第二步:将第一步所得到的混合物、硫组分和硫化促进剂混合揉捏;第三步:对第二步所得到的混合物进行热处理。在公式(I)中,n表示0到10的整数。化合物(I)或其盐最好是S-(3-氨基丙基)硫酸或其盐。
