RUBBER COMPOSITION FOR TIRE USING SURFACTANT

摘要

The tire rubber compd. comprises 0.5-10 wt.% surfactant of formula (1), 60-140 wt.% filler such as carbon black or silica, vulcanization activating agent such as zinc oxide or sulfur to the 100 wt.% of tire rubber compound. The surfactant has alkyl and alkenyl substitute of carbon number 12-24. The surfactant in rubber compd. has polar and nonpolar functional groups simultaneously to improve the dispersion property between the polar filler and nonpolar rubber.
