Description

타이어 접지면에 사용하기 위한 고무조성물Rubber composition for use on tire ground planes

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1 도는 부서짐온도에 대해 도해된 통상적 고무조성물의 전단모듈러스를 나타내고,1 shows the shear modulus of a typical rubber composition illustrated for break temperature,

제 2 (A) 및 2 (B)도는 제 1 도와 유사한 도면이나, 제각기 본 발명을 구체합하는 고무조성물과 비교조성물에 관하여 온도 대 전단 모듈러스 관계와 온도 대 손실인자 관계를 나타낸다.2 (A) and 2 (B) are drawings similar to those of FIG. 1, but show temperature vs. shear modulus and temperature vs. loss factor relationships for rubber compositions and comparative compositions, respectively, which incorporate the present invention.
