The present invention discloses a tread rubber composition. The tread rubber composition according to the present invention contains 1 to 10 parts by weight of resorcinol phenolic alkoxy phosphinate with respect to 100 parts by weight of a raw rubber. According to the same, it is possible to improve heat resistance of a rubber composition by uniformly dispersing contained particles in a rubber, and wet braking performance can be improved by increasing a frictional force with a wet road surface without deteriorating other performance.
본 발명은 트레드고무 조성물을 개시한다. 본 발명에 따르는 트레드고무 조성물은 원료고무 100 중량부에 대하여 레시놀페놀릭알콕시포스피네이트(Resorcinol phenolic alkoxy phosphinate) 1 내지 10 중량부를 포함하는 것을 특징으로 하는데, 이에 의할 때 함유 입자를 고무 내에 균일하게 분산하여 고무조성물의 내열성을 향상시키고 기타 성능하락 없이 습윤 노면과의 마찰력을 증가시켜 Wet Braking 성능을 향상시킬 수 있다.
