Problems solved by technology

[0003] 1. Products used in automotive dynamic vibration absorbers are required to have a certain natural frequency. This frequency is required to be controlled by controlling the hardness of the material and other characteristics. However, the frequency of dynamic vibration absorbers currently on the market generally cannot meet the accuracy requirements. If it exceeds the upper and lower limits, it will cause Product vibration absorption effect failure
[0004] 2. For some vibration absorbers installed in high-temperature areas such as automobile engines, this puts strict requirements on the dynamic thermal fatigue performance of materials, and some materials have serious performance attenuation with the increase of use time, which directly leads to the failure of the product's vibration absorption effect

Abstract

The invention relates to the technical field of dynamic absorber materials and specifically discloses a high temperature-resisting and anti-fatigue dynamic absorber material. The high temperature-resisting and anti-fatigue dynamic absorber material includes the following production raw materials: 60-80 parts of methyl vinyl silicone rubber, 10-30 parts of silicon dioxide, 3-5 parts of coloring pigment, 1-3 parts of heat stabilizer, 4-5 parts of structuring control agent, 2-3 parts of compatilizer and 0.7-1 part of vulcanizing agent. A preparation method thereof comprises the following steps: weighting all the raw materials according to a preset value; adding the raw materials into a blender for blending; detecting and selecting a sizing material with certain hardness, strength and elongation; shaping and molding; adding into a dynamic absorber product mold for primarily vulcanizing; trimming and secondarily vulcanizing; checking, thereby acquiring the high temperature-resisting and anti-fatigue dynamic absorber material. The dynamic absorber material prepared according to the invention has the characteristics of high temperature resistance, tear resistance and fatigue resistance.

Description

technical field [0001] The invention relates to the technical field of dynamic vibration absorber materials, in particular to a high temperature-resistant and fatigue-resistant dynamic vibration absorber material and a preparation method thereof. Background technique [0002] A variety of vibration and noise in the automotive field is caused by resonance. In order to solve this kind of problem, we need a vibration-absorbing product to eliminate this effect. Usually we use rubber built-in counterweights to absorb the vibration of specific parts of the car body to achieve the purpose of noise reduction. However, the existing automotive dynamic shock absorber materials generally have the following problems: [0003] 1. Products used in automotive dynamic vibration absorbers are required to have a certain natural frequency. This frequency is required to be controlled by controlling the hardness of the material and other characteristics. However, the frequency of dynamic vibrati...
