Elastomer composition and pneumatic tire using same |
摘要 |
An elastomer composition comprising a butyl-based rubber (A), as a dispersed phase, including (i) a brominated isobutylene and p-methylstyrene copolymer rubber or (ii) a blend of a butyl rubber, halogenated butyl rubber and/or polyisobutylene rubber and a brominated isobutylene and p-methylstyrene copolymer rubber and a Nylon resin (B), as a matrix phase, selected from Nylon 11, Nylon 6/66 copolymer, Nylon 6 and/or Nylon 66, wherein the matrix phase of the butyl-based rubber/Nylon resin blend composition having titanium oxide (C) compounded therein in an amount of 2.5 to 8% by weight, based upon the weight of the Nylon resin (B), whereby UV degradation can be suppressed and long term outdoor exposure can be withstood and a pneumatic tire using the same. |

1. An elastomer composition comprising a butyl-based rubber (A), as a dispersed phase, including (i) a brominated isobutylene and p-methylstyrene copolymer rubber or (ii) a blend of at least one rubber selected from a butyl rubber, halogenated butyl rubber and polyisobutylene rubber and a brominated isobutylene and p-methylstyrene copolymer rubber and a Nylon resin (B), as a matrix phase, at least one member selected from Nylon 11, Nylon 6/66 copolymer, Nylon 6 and Nylon 66, and any blend thereof, wherein the matrix phase of the butyl-based rubber/Nylon resin blend composition has titanium oxide (C) compounded therein in an amount of 2.5 to 8% by weight, based upon the weight of the Nylon resin (B), wherein said titanium oxide (C) is first mixed with the Nylon resin (B), followed by being mixed with the butyl-based rubber, whereby the titanium oxide (C) is compounded in the matrix phase of the Nylon resin (B) in the elastomer composition. |
