TREAD RUBBER COMPOSITION FOR TIRE

摘要

PURPOSE: A tread rubber composition for a tire is provided to obtain the high temperature of the tire by the friction with the ground, and to generate various colors of the flame for triggering lots of concentration from an audience watching an event. CONSTITUTION: A tread rubber composition for a tire contains 0.1~40 parts of activated metal element by weight for 100 parts of raw rubber by weight. The activated metal element is selected from the group consisting of an alkali metal or an alkaline earth metal. The composition additionally contains a reinforcing agent and other additives. The composition generates various colors of flames at in the wave length of 380~700 nanometers at the visible light area by the heat occurred from the friction between the tire and the ground.
