Anti-shock Rubber

 1. Anti-shock effect of rubber and anti-shock rubber materials
Rubber is characterized by high elasticity and high viscosity. The elasticity of rubber is produced by changes in the conformation of its curly molecules. The interaction of rubber molecules can impede the movement of molecular chains and show the characteristics of viscosity, so that the stress and strain are often in an unbalanced state. The curled long chain molecular structure of rubber and the weak secondary force between the molecules make the rubber material exhibit unique viscoelastic properties, so it has good shock absorption, sound insulation and cushioning properties. Rubber components are widely used to isolate vibration and absorb shock, because they have the characteristics of hysteresis, damping and large reversible deformation.
The hysteresis and internal friction characteristics of rubber are usually represented by loss factor, and the larger the loss factor, the more significant the damping and heat generation of rubber, the more obvious the damping effect. The size of the loss factor of rubber material depends not only on the structure of rubber itself, but also on temperature and frequency.
2. Development and application of anti-shock rubber products
Rubber shockproof products commonly known as rubber shock absorber. There are many kinds of rubber shock absorber, which can be divided into compression type, shear type, torsional type, impact type and mixed type. With the development of science and technology, there are more and more kinds of rubber shock absorbers and more and more applications. In the developing society, rubber shockproof products will receive more and more attention, and its development prospect will be very extensive.
Anti-shock rubber mainly used in:
Construction engineering: Because of the inevitability of the earthquake disaster, in the building, only the addition of anti-shock rubber can mitigate the damage of the disaster, reduce economic losses, and ensure personal safety.
Car: The anti-vibration product is used to control the vibration and noise of the automobile and to improve its control stability.
Railway rolling stock and railway sleeper pads: It can improve the cushioning performance of concrete sleeper rail, reduce the impact of sleeper rail on ballast bed and increase insulation.
Bridge: All the loads on the bridge span structure can be reliably transmitted to the pier, and the deformations of the end horizontal displacement and the rotation angle of the bridge span structure caused by the load can be withstood. The second is to adapt to the expansion and contraction caused by the change of temperature and humidity.
