Tread Rubber Compound for Color Smoke Tire, and Tire Comprising The Compound, and Preparation method thereof

摘要

A tread rubber composition for tires, including a sublimation dye that is activated by heat generated by frictional contact with a road surface to generate smoke having various colors at a wavelength of about 39-76×10−6 cm (390 nm to 760 nm) in a frequency range of about 39.5˜77×1013 vps (39.5×1013 Hz to 77×1013 Hz. In addition, a tire including the tread rubber composition and a method of manufacturing the tread rubber composition are also provided. According to the current invention, the tread rubber composition included in the tire can generate smoke having a single color or mixed colors selected from among various colors, therefore obtaining smoke that gives optimal enjoyment and satisfies requirements of drivers at motor sports events, such as drifting.
