Features rubbers are both high elastic state have high viscosity state, the elastic rubber is crimped by molecular conformational changes generated by interaction between rubber molecules interfere with the movement of the molecular chain, and exhibit sticky characteristics, so that stress and strain often in an unbalanced state. This rubber between curly long chain molecular structure and molecular existence of a weak secondary power; the rubber materials exhibit unique viscoelastic properties, which has a good shock absorption, sound insulation and cushioning. Vibration isolating rubber member and is widely used to absorb the impact, because it has a hysteresis, damping and large deformation can be reversibly characteristics .
Hysteresis and friction characteristics of rubber is usually represented by the loss factor, the greater the loss factor, damping and heat the rubber more significant damping effect is more obvious.
Rubber material loss factor is not only the size and the structure itself, but also on temperature and frequency-dependent rubber. At room temperature, natural rubber (NR) and butadiene rubber (BR) loss factor is small, styrene-butadiene rubber (SBR), chloroprene rubber (CR), ethylene propylene rubber (EPR), polyurethane rubber (PU) and silicon rubber The loss factor centered, butyl rubber (HR) and nitrile rubber (NBR) Maximum loss factor.
Damping rubber material used for the purpose of general points five kinds, namely NR, SBR, BR ordinary rubber materials; NBR for oil vulcanized rubber; CR for weathering vulcanized rubber; IIR for high-damping rubber vulcanization; EPR for Heat vulcanized rubber. NR although a smaller loss factor, but its best overall performance, with excellent flexibility, good fatigue resistance, low heat, low creep, and metal adhesion performance, cold resistance, electrical insulation and processability Hao Therefore NR is widely used as damping purposes, requirements or weathering resistance, low temperature performance, with BR or CR blended with or modified. Shock absorber made of metal-containing -OH groups such as the use of organic acids Nishiue NR, BR and 4 or more carbon atoms has good durability, at 70 ºC × 22h at 40 ºC × 148h compression conditions and permanent deformation were 17.0% and 11.7%.
Rubber damping products mainly rubber shock pad, rubber air springs, rubber fenders (see pictures), sponges and cork rubber shock pad, the elastic coupling joints and flexible pipes and other categories.
rubber cushion. Mostly rubber and metal composite products, double plate, cylindrical type, chip and other forms, for a variety of machinery, instruments, axles, shock absorption and sound insulation pipes .
rubber air springs. It is a good shock absorption and impact resistance than metal springs, mainly for vehicles. Its structure and tubeless tires are somewhat similar to ply layer of pressure within airtight rubber layer, anti-aging oil outside the protective rubber layer.
rubber bearings. A rubber sheet and rigid materials (steel, steel mesh, canvas) bonded. The latter can improve bearing compressive strength, shear strength and confrontation have little effect. Rubber bridge bearings can bridge up the load transfer to the pier, at the same time to adapt to the bridge deformation and reduce vibration. Rubber building bearing can be reduced with the subway and around the vehicle and the effects of earthquakes on buildings.
