Abstract

The invention discloses a formula of shock-reducing rubber. The shock-reducing rubber is particularly prepared from the following raw materials in parts by weight: 15-18 parts of dipropylene glycol methyl ether alkanol amide, 0.05-0.25 part of heavy calcium carbonate, 4.3-8.7 parts of 2 minute-dithio benzothiazole, 8-11 parts of polyacrylate rubber, 1.55-2.35 parts of vinyl acetate maleic acid ester, 0.54-1.23 parts of 4,4 minute-dithiomorpholine, 2.5-3.7 parts of isoprene-butadiene rubber and 5.2-7.5 parts of expanded graphite. The high-elasticity synthetic rubber material improves specific strength of a product, and the product has greater press deformation and quicker restoration speed; after the shock-reducing rubber is used for a high speed train, shake can be more effectively reduced and noise can be more effectively lowered in the use process; the use safety of the product is improved, under the condition of the press deformation being 60 percent, the product cannot crack, and can restore within a shorter time; a manufacturing process is relatively simple, and popularization and application are facilitated.

Description

technical field [0001] The invention relates to a rubber material and a preparation method thereof, in particular to a formula of shock-absorbing rubber, which belongs to the field of rubber. Background technique [0002] The Y-direction rubber spring of the maglev train is a kind of rubber damping part used in the train. Damping material is a material that converts solid mechanical vibration energy into heat energy and dissipates it. It is mainly used for vibration and noise control. When the maglev train is running, due to engine operation and aerodynamic noise, it will cause serious broadband random vibration and noise environment, and it will also stimulate many resonance peaks in the structure and electronic control instrument system, causing fatigue failure and dynamic instability of the structure , so that the accuracy of electronic control equipment is reduced and even malfunctions. In order to improve the damping performance of the structure, the structural materi...
