COLOR TREAD RUBBER COMPOSITION FOR TIRE

摘要

PURPOSE: A color tread rubber composition for tire blended an ultra violet stabilizer with 100% silica and a pigment as a filler and a reinforcing material is provided which improves color fastness having no effect on tensile strength, modules and deformation rate. CONSTITUTION: A color tread rubber composition for tire is blended a polymer, 10-120 pH of 100% silica as a non contaminating filler and reinforcing material, a pigment, an ultra violet stabilizer with conventional tire tread rubber composition. The polymer comprises 10-40 phr of a natural rubber, 0-50 phr of butadiene rubber and 40-80 phr of styrene-butadiene rubber. The pigment uses 2-8 phr of red and yellow azo and 2-8 phr of phthalocyanine.
