Abstract

The invention discloses a rubber vibration reduction device with high anti-aging performance. The rubber vibration reduction device is applied to the technical field of anti-aging rubber reduction device preparation. The rubber vibration reduction device is prepared from 80 to 100 parts of natural rubber, 1 to 6 parts of modified chlorosulfonated polyethylene rubber, 0.5 to 3 parts of sulphur, 1 to 2.5 parts of a vulcanizing agent, 6 to 12 parts of an anti-aging agent, 4 to 10 parts of zinc oxide, 1 to 12.5 parts of white carbon black, 10 to 30 parts of carbon black, 12 to 16 parts of a softening agent, 10 to 19 parts of proportioning rubber, 25 to 45 parts of a filling material, 6 to 8 parts of ore fiber, 1 to 5 parts of an aluminum-zirconium coupling agent, 2 to 4 parts of polyoxyethylene glycol monostearate, 0.5 to 1.5 parts of a crosslinking agent, 1 to 2 parts of an antioxidant, 1 to 3 parts of an accelerant and 3 to 7 parts of magnesium oxide. By using the embodiment, the stability of the natural rubber vulcanization crosslinked bond structure under the high-temperature condition can be improved; the high-temperature heat oxidization aging resistance, ozone resistance and weather resistance performance of the rubber vibration reduction device and the anti-vulcanization reversion resistance performance of the natural rubber are improved.

Description

technical field [0001] The invention relates to the technical field of preparation of aging-resistant rubber, in particular to a rubber shock absorber with high aging resistance and a preparation method thereof. Background technique [0002] Rubber shock absorbers, as an important type of shock-absorbing components, have been widely used in various types of machinery, automobiles, railway locomotives, water vehicles, airplanes and other aircraft. It can be said that rubber shock absorbers are required wherever shock absorption and shock isolation are required. The reason why rubber shock absorbers are so widely used is that it effectively utilizes the following properties of rubber: Rubber has high elasticity and viscoelasticity. [0003] Under the conditions of high load, high strength, and ultra-high temperature (maximum service temperature 110°C), it has good heat aging resistance and dynamic fatigue performance. The high-demand natural rubber shock absorber must be able...
