Rubber composite for sidewall of colored truck radial tire

Abstract

The invention discloses a rubber composite for a sidewall of a colored truck radial tire, comprising the following components in parts by weight: 100 parts of matrix rubber, 5-8 parts of activating agent, 40-70 parts of white carbon black, 3-9 parts of silane coupling agent, 6-10 parts of light-colored rubber oil, 2-6 parts of light-colored tackifying resin, 0.5-3 parts of accelerating agent, 4-8parts of anti-ageing agent, 1-2 parts of vulcanizing agent, 5-8 parts of antistatic agent and 3-6 parts of coloring agent, wherein the matrix rubber is composed of natural rubber, halogenated butyl rubber and rare-earth butadiene rubber; the white carbon black is precipitation-method white carbon black; the accelerating agent is composed of an accelerating agent DM (2,2'-dibenzothiazole disulfide) and an accelerating agent DPG (Dipropylene Glycol); the anti-ageing agent is composed of a non-polluted type light-colored antiozonant, a non-polluted type light-colored antioxidant and an anti-ageing agent TMQ (2,2,4-trimethyl-1,2-dihydroquinoline); the vulcanizing agent is sulfur; and the antistatic agent is a polyethers antistatic agent. The sidewall prepared from the rubber composite provided by the invention not only has a bright color, but also has good flex fatigue resistance; and the rubber composite is mainly used for the sidewall of the colored truck radial tire.

Description

technical field [0001] The invention relates to a rubber composition, in particular to a rubber composition used for sidewalls of colored load radial tires. Background technique [0002] In recent years, in order to adapt to the development trend of automobile tire safety, environmental protection and greenness, non-petroleum resources such as white fillers such as natural rubber and white carbon black have received more and more attention. It is desired to develop rubber compositions for tires using raw materials derived from non-petroleum resources that have characteristics equal to or better than those obtained from petroleum resource materials. For example, in the sidewall rubber of tires, it is required to maintain good durability and at the same time reduce rolling resistance and ensure good flex fatigue resistance. However, compared with the use of petroleum resources, when using silica for reinforcement, the properties such as flex fatigue resistance and reinforceme...

However, compared with the use of petroleum resources, when using silica for reinforcement, properties such as flex fatigue resistance and reinforcement performance are affected

In addition, traditional tires are black or a single color, which cannot bring aesthetic enjoyment to people. With the development of vehicle specialization in the automotive industry, such as military vehicles, fire trucks, sanitation vehicles, school buses, etc., there are new changes to the color of the sidewall of vehicle tires. requirements
