Abstract

본 발명은 변성 실리카를 트래드용 고무조성물에 적용함으로써 가류특성을 개선하고, 충진제의 균일한 분산성 확보하여 내마모성이 개선된 타이어용 고무에 관한 것이다.The present invention relates to a rubber for tires by improving modified vulcanization characteristics by applying modified silica to a rubber composition for treads and ensuring uniform dispersibility of fillers.

본 발명에 적용된 변경 실리카는 관능기를 가진 저 분자량 이소프렌 또는 SBR 고무와 실리카를 용매 중에서 혼합한 후 탈용매 및 열처리 건조하여 제조한다.The modified silica applied to the present invention is prepared by mixing a low molecular weight isoprene or SBR rubber having a functional group with silica in a solvent, followed by desolvent and heat treatment drying.
