Abstract

The invention belongs to the technical fields of rubber tires and chemical manufacturing, and relates to a colorful rubber composition for a tire sidewall and a preparation method of the colorful rubber composition. The colorful rubber composition for the tire sidewall is prepared from the following raw material ingredients in parts by weight: 30-40 parts of natural rubber, 10-20 parts of ethylene propylene terpolymer, 45-55 parts of chlorinated butyl rubber, 1-2 parts of tackifying resin, 1.5-2.5 parts of an activating agent without carbon black, 1-2 parts of a dispersant, 0.5-1 part of a no-pollution anti-aging agent, 25-30 parts of kaolin, 30-40 parts of titanium pigment, 19-24 parts of a coloring agent, 1-1.5 parts of an accelerant, 0.4-1 part of sulphur and 0.1 part of an anti-scorching agent. In combination with a three-phase mixing process in the preparation process, the problems of low flexing resistance, low aging resistance and high color fading possibility of a colorful rubber tire sidewall in the prior art are solved. The rubber composition not only meets the requirements of tire sidewall rubber for high flexing resistance and high aging resistance, but also meets the aesthetic vision for a user to modify tire appearance.

Description

technical field [0001] The invention belongs to the technical field of rubber tires and chemical manufacturing, and relates to a colored rubber composition for tire sidewalls and a preparation method thereof, which meet the requirements of tire sidewall rubbers with high flex resistance and high aging resistance, and satisfy users' requirements for tire appearance Aesthetic vision for grooming. Background technique [0002] The sidewall is an important part of the structural integrity of the tire. It protects the carcass from lateral physical and chemical damage, and is also the most eye-catching part of the tire. The development of tires in color has gone through the process of maintaining the original white color of the rubber at first, and adding various color additives to the colorful tires, because of their poor strength and tear resistance, poor aging resistance, high cost, After a long time of use, the rubber compound will gradually turn yellow and brown and other re...
