Embodiment 1

[0034] A composite rubber composition for automobile tires provided by the present embodiment, in parts by weight, comprises:

[0035] 55 parts of natural rubber; natural rubber is extracted from Hevea.

[0036] 70 parts of synthetic rubber; synthetic rubber includes solution-polymerized styrene-butadiene rubber.

[0037] 50 parts of styrene thermoplastic elastomer;

[0038] 20 parts of tackifier; tackifier includes hydrogenated rosin.

[0039] 60 parts of carbon black;

[0040] 8 parts of vulcanizing agent.

[0041] The present embodiment also provides a method for preparing the above-mentioned composite rubber composition for automobile tires. After mixing natural rubber, styrene-based thermoplastic elastomer and synthetic rubber, the tackifier and carbon black are added in sequence and mixed. After heating and forming, the formed rubber is finally vulcanized by adding a vulcanizing agent at 100-200°C.

Abstract

The invention provides a composite rubber composition for an automobile tire, and relates to the technical field of automobile tire material. The composite rubber composition for the automobile tire is prepared from the following components in parts by weight: 40 to 55 parts of natural rubber, 50 to 70 parts of synthetic rubber, 10 to 50 parts of styrene thermoplastic elastomer, 5 to 20 parts of tackifier, 50 to 60 parts of carbon black, and 4 to 8 parts of vulcanizer. The composite rubber composition has the advantages that the cost is low, the environment-friendly effect is realized, and theabrasion-resistant and explosion-resistant properties are better. A preparation method of the composite rubber composition comprises the following steps of mixing and blending the natural rubber, thestyrene thermoplastic elastomer and the synthetic rubber, sequentially adding the tackifier and the carbon black, mixing, heating and forming; finally, adding the vulcanizer into the formed rubber atthe temperature of 100 to 200 DEG C to vulcanize. The preparation method has the advantages that the raw materials are fully used, and the operability is stronger.

Description

technical field [0001] The present invention relates to the technical field of automobile tire materials, and particularly relates to a composite rubber composition for automobile tires and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry and transportation industry, and the rapid development of highway construction, especially highways, various high-performance tires are urgently needed. Among them, rubber is the main material for making tires, accounting for 45% to 50% of the tire mass. In fact, a tire is a composite of fibers and metals that are completely fixed and bonded together with rubber. [0003] At present, the total production value of tires has accounted for more than half of the rubber industry, ranking first in all kinds of rubber products, so the demand for rubber is increasing; Under the premise of the same performance, the required raw materials are more and the cost is higher, which puts gr...
