Definitions

  • the rubber composition for tires of the present invention comprises a rubber component, which provides rubber elasticity to the composition.

  • diene rubber is preferable, and isoprene skeleton rubber, styrene-butadiene rubber (SBR), butadiene rubber (BR), and chloroprene rubber (CR) are more preferable.
  • the isoprene-skeletal rubber is a rubber having isoprene units as a main skeleton, and specific examples thereof include natural rubber (NR), synthetic isoprene rubber (IR), and the like.
  • the quinoline antioxidant preferably has a dihydroquinoline moiety, more preferably a 1,2-dihydroquinoline moiety.
  • Specific examples of the quinoline antioxidant include a polymer of 2,2,4-trimethyl-1,2-dihydroquinoline (antioxidant TMDQ), 6-ethoxy-2,2,4-trimethyl-1 ,2-dihydroquinoline, 6-anilino-2,2,4-trimethyl-1,2-dihydroquinoline and the like.

Abstract

La présente invention vise à fournir une composition de caoutchouc pour pneumatique qui permet à la fois une résistance au grillage et une résistance à l'efflorescence. La présente invention concerne par conséquent par une composition de caoutchouc pour pneumatique caractérisée en ce qu'elle comprend un composant de caoutchouc, un agent anti-âge à base d'amine, et un retardateur de vulcanisation, et en outre caractérisée en ce que l'agent anti-âge à base d'amine est représenté par la formule générale (1), la teneur en agent anti-âge à base d'amine est de 0,1 partie en masse ou plus pour 100 parties en masse du composant de caoutchouc, le retardateur de vulcanisation est représenté par la formule générale (2), et la teneur en retardateur de vulcanisation est de 0,005 partie en masse ou plus pour 100 parties en masse du composant de caoutchouc. Dans la formule (1), R1 et R2 représentent chacun indépendamment un groupe hydrocarboné saturé monovalent ; dans la formule (2), R3 et R4 représentent chacun indépendamment un groupe hydrocarboné aromatique monovalent substitué ou non substitué, et R5 représente un groupe alkyle à substitution halogène.]
