마른 노면과 젖은 노면에서의 제동거리 특성이 우수한 트레드 고무조성물{Good dry and wet stop distance PCR Tread compound}Tread rubber composition with excellent braking distance characteristics on dry and wet roads {Good dry and wet stop distance PCR Tread compound}

본 발명은 트레드 고무조성물에 관한것으로, 보다 상세하게는 마른 노면과 젖은 노면에서 저연비 성능 및 제동성이 우수한 승용차(Passenger car, PCR)용 트레드 고무조성물에 관한 것이다.The present invention relates to a tread rubber composition, and more particularly to a tread rubber composition for a passenger car (Passenger car, PCR) having excellent fuel efficiency and braking properties on dry and wet road surface.

For example, low traction resistance, which is closely related to wet traction and low fuel consumption, and noise, abrasion resistance, and braking performance.

그러나 이들 성능은 서로 이율배반적인 것으로서, 타성능의 희생없이 원하는 특정의 성능을 향상시키는 것이 매우 어려우며, 더군다나 이들 성능을 동시에 향상시키는 것은 더욱 어려운 문제이다.However, these performances are mutually exclusive, and it is very difficult to improve the specific performance desired without sacrificing other performance, and even more difficult to improve these performances simultaneously.

It is an object of the present invention to provide a rubber tread composition for PCR tread that improves driving safety such as braking force on dry and wet roads while maintaining the same fuel economy and wear performance.

The solution black styrene butadiene rubber (S-SBR) 35 to 40 parts by weight and butadiene rubber (BR) is characterized in that 25 to 45 parts by weight of carbon black based on 100 parts by weight of the raw material rubber.
