Improved high-elasticity synthetic rubber material

Abstract

The invention discloses an improved high-elasticity synthetic rubber material which is prepared from the following raw materials in parts by weight: 15-18 parts of vinyl silicon resin, 0.05-0.25 part of accelerator, 4.3-8.7 parts of polydimethylsiloxane, 8-11 parts of natural rubber, 1.55-2.35 parts of talcum powder, 0.54-1.23 parts of cyclohexyl thiophthalimide, 2.5-3.7 parts of plasticizing and softening agent and 5.2-7.5 parts of anti-aging agent. The high-elasticity synthetic rubber material disclosed by the invention enhances the specific strength of the product, increases the compression set and recovery speed of the product, and can effectively reduce shocks and lower noises when being applied to high speed trains. The invention enhances the use safety of the product, so that the product can not rupture under the condition of 60% compression set, and can recover within a short time. The manufacturing process is simple, and thus, is convenient for popularization.

Description

[0001] technical field [0002] The invention relates to a rubber material, in particular to an improved high-elasticity synthetic rubber material, which belongs to the field of rubber. Background technique [0003] 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 material and...
