Abstract

The invention relates to damping rubber which is characterized in that the main material of the damping rubber comprises the main ingredients of polyether polyurethane rubber and polyester polyurethane rubber, and the mass ratio of the polyether polyurethane rubber to the polyester polyurethane rubber is (60-80):(40-20); the damping rubber also comprises polynorbornene rubber, and the mass of polynorbornene rubber is 10-15% of the total mass of the polyether polyurethane rubber and the polyester polyurethane rubber. The damping rubber of the invention solves the problems of low specific strength, small stressed deformation quantity, low restoring speed and great permanent deformation quantity of the traditional rubber spring.

Description

technical field [0001] The invention relates to the rubber product industry in the chemical industry field, in particular to a rubber composition for a Y-direction rubber spring of a maglev train with high specific strength and high elasticity. 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 dampin...
