Problems solved by technology

The fast running of the tires and the intense friction with the road surface generate a lot of "humming" low-frequency noise, which is transmitted to the car through the iron sheet at the lower part of the cockpit, which is obviously irritating to people. Long-term exposure to noise environments is very harmful to the human body , fatigue increases, dizziness appears, the duration is longer, the intensity is greater, it is easy to cause hearing loss, and it will also cause varying degrees of damage to the nervous system. The most closely related to tire noise is the car tire. The material of tires can reduce noise, which has become a hot research topic in the automotive industry

Abstract

The invention provides an automobile tire rubber material with excellent sound absorption performance and a preparation method thereof, and relates to the field of rubber materials. The composition isprepared from the following components in parts by weight: 30-50 parts of natural rubber, 60-80 parts of epoxidized solution polymerized styrene-butadiene rubber, 40-60 parts of butadiene rubber, 20-30 parts of high-strength methyl vinyl silicone rubber, 5-15 parts of eucommia ulmoides gum grafted butyl methacrylate, 4-8 parts of polyisoprene, 5-10 parts of zinc oxide whisker, 5-10 parts of porous carbon nanotubes, 5-10 parts of aluminum oxide, 10-15 parts of nano attapulgite, 30-40 parts of carbon black, 20-30 parts of organic modified white carbon black, 20-30 parts of nano calcium carbonate, 5-10 parts of microcrystalline wax, 5-10 parts of stearic acid, 1-3 parts of sulfur, 1-3 parts of a homogenizing agent A78, 0.1-5 parts of an accelerant and 1-5 parts of an anti-aging agent. The automobile tire rubber material provided by the invention has excellent mechanical properties, excellent sound absorption and heat conduction properties, and great market application prospects, and canbe widely popularized to reduce noise brought by automobile tires on the road surface.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to an automobile tire rubber material with excellent sound-absorbing performance and a preparation method thereof. Background technique [0002] Usually installed on the metal hub, it can support the body, buffer the external impact, realize the contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which shows the ability of tires to consume rubber. [0003] Now the main component ...
