Abstract

본 발명은 수평균분자량이 15만 내지 25만이고 중량 평균분자량이 105만 내지 115만인 스티렌-부타디엔 공중합 고무 70 내지 100 중량부와 부타디엔 고무 0 내지 30 중량부, 및 통상의 고무 배합제로 이루어지는 것을 특징으로 하는 소형 타이어의 트레드용 고무 조성물에 관한 것으로, 종래의 고무 조성물에 비하여 분자량이 5만 내지 15만 정도 증가된 스티렌-부타디엔 공중합 고무를 사용함으로써 내마모성을 향상시킨 소형 타이어의 트레드용 고무 조성물에 관한 것이다.The present invention is characterized by consisting of 70 to 100 parts by weight of styrene-butadiene copolymer rubber and 0 to 30 parts by weight of butadiene rubber, and a conventional rubber compounding agent having a number average molecular weight of 150,000 to 250,000 and a weight average molecular weight of 10,500,000 to 1.15 million. The present invention relates to a tread rubber composition for compact tires, and to a tread rubber composition for improving abrasion resistance by using a styrene-butadiene copolymer rubber having a molecular weight of about 50,000 to 150,000 compared to a conventional rubber composition. will be.
