Abstract
The invention discloses a high-damping shock-absorbing material for automobile body suspension and a preparation method and application thereof. The high-damping shock-absorbing material for automobile body suspension comprises a raw rubber system and nitrine formate. The raw rubber system comprises natural rubber, isobutylene-isoprene rubber and high-activity polyisobutylene rubber, and the content of alpha-terminal double bonds of the high-activity polyisobutylene rubber is not lower than 60%. The high-damping shock-absorbing material has the advantages of high damping property, shock-absorbing durability, low attenuation property, better fatigue durability, dimensional stability and the like, can ensure the damping shock-absorbing property under the dynamic condition of a vehicle when being used for vehicle body suspension, greatly improves the fatigue durability property, and delays the performance attenuation caused by product deformation.a The service life of the product is guaranteed, and meanwhile the comfort of the whole vehicle is improved.
Description
technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a high-damping shock-absorbing material for automobile body suspension and a preparation method and application thereof. Background technique [0002] Body suspension refers to the insertion of relatively soft elastic elements between the body and the frame, so that the force transmission between the two can be attenuated and isolated. The body mount plays the role of supporting the body, limiting the deviation of the body, and isolating vibrations. The body mount must have good shock isolation performance, and the vertical direction requires low stiffness and can be maintained for a long time. Based on the function of the body mount, the rubber material for the body mount is required to have high damping attenuation characteristics and good durability. At the same time, due to long-term exposure to the frame position, the material needs to have high weather resistance. C...
