Abstract:
Provided is a method for producing a vulcanized rubber composition, including: a first kneading step of obtaining a kneaded mixture comprising a rubber component comprising at least one selected from the group consisting of natural rubbers and synthetic rubbers, a filler comprising an inorganic filler, and a sulfur-containing silane coupling agent; a second kneading step of adding sulfur and a vulcanization accelerator to the kneaded mixture, followed by kneading, to thereby obtain an unvulcanized rubber composition; and a vulcanization step of vulcanizing the unvulcanized rubber composition to thereby obtain a vulcanized rubber composition having a glass transition temperature of −30° C. to 0° C. by; wherein specific aminoguanidines are added, followed by kneading, in the first kneading step.

Claim (Index 1):
A method for producing a vulcanized rubber composition, comprising:\n a first kneading step of obtaining a kneaded mixture comprising: a rubber component comprising at least one selected from the group consisting of natural rubbers and synthetic rubbers, a filler comprising an inorganic filler, and a sulfur-containing silane coupling agent; a second kneading step of adding sulfur and a vulcanization accelerator to the kneaded mixture, followed by kneading, to thereby obtain an unvulcanized rubber composition; and a vulcanization step of vulcanizing the unvulcanized rubber composition to thereby obtain a vulcanized rubber composition having a glass transition temperature of \u221230\u00b0 C. or more and 0\u00b0 C. or less, wherein at least one selected from the group consisting of compounds represented by formulae (1), (2), and (3) below is added, followed by kneading, in the first kneading step: wherein X is an acid that forms a salt together with a guanidine moiety; wherein X is an acid that forms a salt together with a guanidine moiety, R 1  and R 2  are each independently any one selected from the group consisting of a hydrogen atom and an alkyl group, a cycloalkyl group, an aryl group, an alkyl aryl group, and an alkenyl group which have 1 to 18 carbon atoms, these groups each optionally having one or more substituents containing at least one selected from the group consisting of a sulfur atom, a nitrogen atom, and an oxygen atom; and wherein X is an acid that forms a salt together with a guanidine moiety.
