Abstract

The invention discloses a novel anti-compression rubber formula. The novel anti-compression rubber is prepared from the following raw materials, by weight, 15-18 parts of zinc diethyl dithiocarbamate, 0.05-0.25 part of dimethicone, 4.3-8.7 parts of ethylene propylene rubber, 8-11 parts of aluminum nitrate, 1.55-2.35 parts of butyl bromide, 0.54-1.23 parts of benzoyl peroxide, 2.5-3.7 parts of mildew inhibitor and 5.2-7.5 parts of hydrated zinc borate. The provided high-elasticity synthetic rubber material raises the product ratio intensity, the compressive deformation of the product is large, the recovery speed is fast, the provided rubber is applied to high-speed trains, and effective shock reduction and noise reduction during the usage process can be ensured. The usage safety of the product is raised, the product cannot be cracked when the compressive deformation is 60% and can recover in a short time. The manufacturing technology is relatively simple and is convenient for popularization and application.

Description

technical field [0001] The invention relates to a rubber material and a preparation method thereof, in particular to a formula of a novel compression-resistant 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 str...
