Abstract

본 발명은 보강제로시 입자경 및 응집체 크기가 크고 응집체 구조가 발달된 카본블랙을 사용함으로써 고무조성물의 분산성이 개선되고, 결합재로서 실리카 함량이 적은 유기실란을 사용함으로써 발열측성 및 회전저항이 개선된 트럭 및 버스용 타이어 트레드 고무조성물에 관한 것이다.The present invention improves the dispersibility of the rubber composition by using carbon black having a large particle size and aggregate size as a reinforcing agent, and an organic silane having a low silica content as a binder, thereby improving exothermicity and rotational resistance. A tire tread rubber composition for trucks and buses.

본 발명에서 사용되는 카본블랙은 요오드 흡수가가 90~120mg/g, 질소흡착비표면적이 100~140㎡/g, 디부틸프탈레이트 흡유량이 130~165ml/100g, 착색력이 95~110%이며, DST가 0.08~0.15㎛, △ DST가 0.04~0.08㎛인 것이 바람직하며, 실리카 처리된 유기실란은 실리카의 함량이 5~15중량%이고, 실란의 함량이 95~85중량%인 것이 바람직하다.The carbon black used in the present invention has an iodine absorption value of 90 to 120 mg / g, a nitrogen adsorption specific surface area of 100 to 140 m 2 / g, a dibutyl phthalate oil absorption of 130 to 165 ml / 100 g, and a coloring power of 95 to 110%, DST Is preferably 0.08 ~ 0.15㎛, DELTA DST is 0.04 ~ 0.08㎛, Silica-treated organosilane is preferably 5 to 15% by weight of silica, 95 to 85% by weight of silane.

카본블랙의 사용량은 원료고무 100중랴부에 대하여 40~60중량부이고, 실리카 처리된 유기실란의 사용량은 3~15중량부이다.The use amount of carbon black is 40 to 60 parts by weight based on 100 parts of the raw material rubber, and the amount of silica treated organosilane is 3 to 15 parts by weight.
