Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a heat-resistant and shock-absorbing rubber material. Background technique [0002] With the rapid development of modern industry, vibration and noise have become serious problems in various fields. It will reduce the operating accuracy, affect product quality, shorten product life, make high-precision instruments not work normally, endanger safety, and make equipment or structures Early damage, pollute the environment and affect human health. Therefore, research and mastery of vibration control and noise control technology has become a major issue facing the industrial development of various countries. [0003] The most widely used and most effective method is to use various shock absorbing products, especially rubber shock absorbing products, which can effectively isolate the vibration and excitation source, and can also moderate the vibration of the vibrating body, so it is wid...
