Problems solved by technology

[0002] With the continuous improvement of people's living standards, automobiles have entered thousands of households. At the same time, with the use of auto parts, the impact of environmental factors has brought great challenges to auto parts. Automotive rubber is not only used as a Accessories are one of the important protection components of the car. Due to the great influence of different weather on the rubber material, it will cause the rubber to age prematurely, cause the vibration of the parts, and affect the work of the car. Shock-absorbing rubber is widely used in various parts of the vehicle to reduce vibration, sound insulation, Cushioning and other functions have extremely strict requirements on the performance of rubber. However, the performance of rubber products currently used is not good, and they are prone to aging and water seepage, which makes the rubber unable to absorb shock and easily cause danger.

Abstract

The invention discloses a preparation method of automotive damping rubber. The method comprises the steps of raw material preparation, raw material processing, plastifying, mixing, vulcanization, molding, detection and the like. According to the preparation method of the automotive damping rubber, the rubber synthesized by natural rubber, butadiene styrene rubber and ethylene propylene terpolymer has abrasive resistance, heat resistance and ageing resistance, has good damping and buffering effects, generates extremely low noise, and has a certain sound insulation effect. Barium sulfate is added, the water resistance of the rubber is improved, water seepage quantity is reduced, and corrosion and ageing of a rubber product are prevented. The physical and mechanical properties of a sizing material are improved through silicon dioxide and the fatigue resistance is improved. Compared with the other inventions, the automotive damping rubber is not easy to age, long in service life, good in damping effect and water resistance, high in security performance and worthy of later promotion, and resources are saved.
