Abstract

본 발명은 경주용 또는 고속주행 승용차용 타이어 트레드 고무 조성물에 관한 것으로서, 더욱 상세하게는 용액 또는 유화 중합 SBR과 고보강성 카본블랙 및 공정유를 혼합한 카본 마스터 배치(이하,CMB라 함)와 천연고무, 용액 또는 유화중합SBR 및 아세틸렌계 또는 펜타디엔계 수지를 포함하는 타이어 트레드 고무조성물에 관한 것으로서, 마른 노면에서의 제동 성능, 핸들링 성능을 향상시키며, 특히, 경주 및 고속주행시 마모, 파열 및 청킹(chunking)현상을 개선시킨 타이어 트레트 고무 조성물에 관한 것이다.The present invention relates to a tire tread rubber composition for racing or high speed passenger cars, and more particularly, to a carbon master batch (hereinafter referred to as CMB) and a mixture of a solution or emulsion polymerization SBR, high reinforcement carbon black and process oil. A tire tread rubber composition comprising rubber, solution or emulsion polymerization SBR and acetylene- or pentadiene-based resins, which improves braking performance and handling performance on dry road surfaces, particularly in race, high-speed driving, abrasion, rupture and chunking. The present invention relates to a tire tread rubber composition having improved chunking.
