Problems solved by technology

However, metal materials are not easy to bond with rubber. In order to obtain high-performance tires with rubber-metal skeleton materials, bonding technology is indispensable.
[0003] However, if the tire is driven under high temperature and high load for a long time, it will inevitably cause the aging of the rubber. The adhesive performance of the aged rubber and the cord will be reduced, which will cause the rubber to separate from the cord, resulting in tire delamination, wire breakage and other quality problems. question
In the prior art, by adding anti-aging agent to the adhesive, the anti-aging ability of the rubber compound is enhanced, thereby prolonging the service life of the tire, but the anti-aging agent will also be worn out, and it is easy to lose its function after long-term use, which also leads to tire failure. The main cause of problems such as delamination

Embodiment 1

[0023] A preparation method for an aging-resistant rubber adhesive applied to automobile tires, comprising the following steps:

[0024] (1) Preparation of slow-release carrier: select hollow natural fibers to rinse first to remove surface impurities, and select plant fibers for the hollow natural fibers, including but not limited to cotton fibers, flax fibers, jute fibers, coconut shell fibers, bamboo fibers, ramie Fiber, loofah fiber or any several, select bamboo fiber in the present embodiment. The hollow cavity inside the plant fiber can hold the anti-aging agent and play a slow-release role. In addition, the plant fiber has high toughness, and has a high water absorption and swelling property to form a three-dimensional fiber network structure, which can improve the bonding of the adhesive. strength and stability. After it is dried in the air, it is vacuumized, so that the hollow natural fiber is placed in a low-pressure environment with a pressure of 20% of atmospheric ...

Embodiment 3

[0039] A preparation method for an aging-resistant rubber adhesive applied to automobile tires, comprising the following steps:

[0040] (1) Preparation of slow-release carrier: select hollow natural fibers to rinse first to remove surface impurities, and select plant fibers for the hollow natural fibers, including but not limited to cotton fibers, flax fibers, jute fibers, coconut shell fibers, bamboo fibers, ramie Fiber, loofah fiber or any several, in the present embodiment, select loofah fiber for use. The hollow cavity inside the plant fiber can hold the anti-aging agent and play a slow-release role. In addition, the plant fiber has high toughness, and has a high water absorption and swelling property to form a three-dimensional fiber network structure, which can improve the bonding of the adhesive. strength and stability. After it is dried, it is subjected to vacuum treatment, so that the hollow natural fiber is placed in a low-pressure environment with a pressure of 40...

Abstract

The invention discloses a preparation method of an anti-aging rubber adhesive applied to automobile tires, and belongs to the technical field of tire adhesive production. The method comprises the following four steps: preparation of a slow-release carrier, preparation of a supported anti-aging agent, preparation of a master batch and preparation of the adhesive. Plant fiber subjected to low-temperature plasma activation treatment is used as a carrier of a magnetic composite anti-aging agent, and the stability of the magnetic composite anti-aging agent is improved through a retention aid, so that the slow release effect of the anti-aging agent can be greatly improved, and the problem of poor anti-aging persistence of a common rubber adhesive is solved.

Description

technical field [0001] The invention belongs to the technical field of tire adhesive production, and in particular relates to a preparation method of an aging-resistant rubber adhesive applied to automobile tires. Background technique [0002] With the rapid development of road traffic, there are more and more high-grade roads, which pose a greater test to the quality of automobile tires. At present, most tires are made by compounding various skeleton materials and reinforcing materials in the rubber base material to meet the strength of the tire. By adding an adhesive to the cord hanging glue, the rubber and the cord can act as a bridge to produce a firm chemical bond, improve the bonding strength, and improve the rubber coating state of the cord. However, metal materials are not easy to bond with rubber. In order to obtain high-performance tires with rubber-metal skeleton materials, bonding technology is indispensable. [0003] However, if the tire is driven under high t...
