Abstract

The invention discloses a non-polluting wear-resistant seam allowance rubber material and a preparation method thereof. The rubber material comprises the following components in percentage by weight,20-50 phr of natural rubber, 15-35 phr of butadiene styrene rubber, 10-30 phr of butadiene rubber, 15-35 phr of ethylene propylene rubber, 50-80 phr of carbon black, 1-10 phr of a softening agent, 2.0-5.0 phr of zinc oxide, 1.0-3.0 phr of stearic acid, 1.0-4.0 phr of a triazine anti-aging agent, 0.5-3.0 phr of a phenolic antioxidant, 1.0-2.5 phr of sulfur, 0.3-1.0 phr of alkylphenol disulfide, 1.0-3.0 phr of an accelerant and 4-8 phr of other components. The non-polluting wear-resistant seam allowance rubber material solves the problem of migration pollution of a seam allowance part of a new generation of color tire on the premise of meeting the key performances of wear resistance, protection and the like of the seam allowance rubber material.

Description

technical field [0001] The invention relates to the technical field of automobile tire materials, in particular to a non-polluting bead wear-resistant rubber material and a preparation method thereof. Background technique [0002] Tires are the key components of automobiles. On the premise of ensuring the safety of use, consumers have higher and higher requirements for gorgeous appearance. Colored tires have always been the darling of the high-end market and a channel for consumers to show their individuality and identity. Traditional colored tires are mostly white characters or white rings, and a thicker white rubber strip is compounded on the sidewall, and then a thinner black film is covered on it. After vulcanization, the white characters or shapes at the bottom are exposed through grinding. Its formula and process are less difficult to realize, and most tire companies have such products for sale. Since it needs to be realized through the grinding process, the colored ...
