Abstract

The invention provides a rubber composition for producing a color tyre. The color tyre comprises a rubber composition of tyre surface, a rubber composition of tyre sidewall, an outer protective rubber composition and sealing layer rubber composition. In a primary color glue of the rubber composition of tyre surface, the rubber composition of tyre sidewall and the outer protective rubber composition, black carbon black is substituted by white carbon black; 1574 color masterbatch, 2507 color masterbatch and titanium dioxide in a certain proportion are added to realize coloration of the rubber composition of tyre surface, the rubber composition of tyre sidewall and the outer protective rubber composition; in the sealing layer rubber composition, black carbon black is substituted by white carbon black; and black masterbatch and titanium dioxide in a certain proportion are added to avoid blackening tendency of the sealing layer, so as to realize production of the color tyre as well as guarantee wear resistance of the color tyre. The produced color tyre can satisfy national test standard.

Description

technical field [0001] The present invention relates to a rubber composition for producing colored tires. Background technique [0002] At present, automobile tires are mainly black, and there are no tires with diversified colors. Contents of the invention [0003] In order to realize the production of colored tires and ensure the wear resistance of the tires, the invention proposes a rubber composition for producing colored tires. [0004] For this reason, the technical scheme of the present invention is: a kind of rubber composition of producing color tire, is made up of tire tread rubber composition, tire sidewall rubber composition, outer sheath rubber composition, sealing layer rubber composition, its Features: [0005] (1) The tire tread rubber composition is composed of primary color rubber, 1574 color masterbatch, 2507 color masterbatch, and titanium dioxide, as follows: [0006] a. The parts by mass of primary color glue are: domestic 5# glue is 20-30 parts, bu...
