The present invention relates to an eco-friendly tire rubber composition for winter which comprises: 100 phr of synthetic rubber; greater than 0 and less than 15 phr of glass bubbles; and modified vegetable oil including oleic triglycerides and methyl esters, wherein the total amount of the oleic triglyceride and methyl ester is 10 to 40 phr and the glass bubbles have a static strength of 2000 to 8000 psi and a density of 0.2 to 0.5 cc. According to the present invention, fuel efficiency and low-temperature snow performance can be improved by applying the modified vegetable oil to the rubber composition, and ice performance can be improved by implementing a spike effect by breaking the glass bubbles while driving by further applying the glass bubbles.

    본 발명은, 겨울용 친환경 타이어 고무 조성물에 관한 발명으로서 100phr의 합성고무, 0 초과 15phr 이하의 글라스 버블 및 올레익 트리 글리세라이드 및 메틸에스테르를 포함하는 개질된 식물성 오일을 포함하며, 올레익 트리 글리세라이드 및 메틸에스테르의 총량은 10~40phr이고, 글라스 버블은 2000~8000psi의 정적 강력 및 0.2~0.5cc의 밀도를 가지는 것을 특징으로 한다. 본 발명에 따르면, 고무 조성물에 개질된 식물성 오일을 적용하여 연비 성능과 저온 스노우 성능을 향상시킬 수 있으며, 글라스 버블을 더 적용하여 주행 중 글라스 버블의 깨짐에 의한 스파이크 효과를 구현하여 아이스 성능을 향상시킬 수 있다.
