Abstract
The present invention relates to a composition for a tire tread, comprising a resin alternative to a process oil. The composition for a tire tread, according to the present invention, can satisfy basic physical properties required as a tire, such as tensile strength, wear resistance, durability, and hardness, and improve the gripping force without a big increase in rolling resistance. A tire manufactured from the composition has the improved gripping force, particularly on wet road surfaces, and thus may be used for manufacturing a high-performance tire with excellent breakability, thereby being capable of increasing product competitiveness.
Claims9
A composition for a tire tread, comprising at least one resin selected from the group consisting of a methylstyrenated phenol-based resin, and a hydrocarbon-based resin, and at least one resin selected from the group consisting of a terpene phenol resin and a hydrogenated hydrocarbon-based resin,
- wherein the methylstyrenated phenol-based resin and the hydrocarbon-based resin do not comprise a softening point measured by ASTM E 28, and
- wherein the hydrogenated hydrocarbon-based resin and the terpene phenol resin comprise a softening point measured by ASTM E 28.
