Problems solved by technology

[0003] At present, most of the vibration damping parts used in the automotive field manufactured by a large number of imported brands use polyepoxide. The production cost of this type of vibration damping parts is high, and it cannot effectively reduce vibration after long-term use.
In order to pursue low cost, the vibration damping and damping parts used in the automobile field manufactured by domestic brands use asphalt as the main material, which greatly reduces the production cost and seriously pollutes the environment, and the vibration and noise reduction effect is not obvious.
[0004] Therefore, in order to compromise, many manufacturers currently use rubber as the main material for manufacturing vibration damping parts. Although the vibration damping performance can be greatly improved, but The cost is high; and the main rubber material is flammable, and the vibration damping parts made of the main rubber material have poor flatness

Abstract

The invention relates to a vibration-reducing damping part. The vibration-reducing damping part comprises vibration-reducing damping part rubber and an aluminum foil, and the vibration-reducing damping part rubber is arranged on the aluminum foil in a laminated mode. The vibration-reducing damping part rubber is prepared from, by mass, 20%-30% of butyl rubber, 10%-15% of polyisobutene, 30%-40% of pottery clay, 4%-8% of terpene resin, 20%-30% of calcium carbonate and 3%-8% of paraffin oil. The vibration-reducing damping part has the advantages of being good in flame-retardant and damping effects, good in flatness, not prone to generate bubbles, low in cost and good in tensile strength, tearing strength and wear-resisting property.

Description

technical field [0001] The invention relates to the field of automobile vibration damping components, in particular to a vibration damping element for automobiles and a preparation method thereof. Background technique [0002] Cars are one of the most important means of transportation in modern society. With the progress of social civilization, people have higher and higher requirements for car comfort. As a special accessory to improve car comfort, the role of vibration reduction system is becoming more and more important. It can effectively attenuate the vibration quickly and reduce the amplitude quickly, play a role in damping vibration, and improve the smoothness and handling stability of the car. At present, the interior of automobiles sold on the market is equipped with vibration-reducing damping parts, and the damping parts are attached to the steel plate wall on the inner surface of the vehicle body to reduce noise and reduce vibration. [0003] At present, most of ...
