Title:
METHOD FOR LOWERING DYNAMIC-TO-STATIC MODULUS RATIO OF VULCANIZED RUBBER
Document Type and Number:
WIPO Patent Application WO/2013/018815
Kind Code:
A1
Abstract:
A method for lowering the dynamic-to-static modulus ratio of a vulcanized rubber, comprising the first step of kneading together a rubber component, a filler, and a compound represented by formula (I) or a salt thereof, the second step of kneading together the kneaded mixture obtained in the first step, a sulfur component and a vulcanization accelerator, and the third step of subjecting the kneaded mixture obtained in the second step to heat treatment. In formula (I), n is an integer of 0 to 10. It is preferable that the compound represented by formula (I) or salt thereof is S-(3-aminopropyl)thiosulfuric acid or a salt thereof.
