Environmental protection damping damping and noise reduction material uses the green butyl rubber as the base material to restrain the damping sheet, and inorganic materials with different shapes, shapes and particle sizes as the mixed materials. 

By adjusting the combination of inorganic fillers and controlling the interface structure between fillers and binders, damping and vibration reduction are realized by the friction between fillers, polymers and fillers (the materials are subject to alternating stress In order to achieve the purpose of high-efficiency noise reduction, hysteresis strain occurs, mechanical loss is formed and then damping effect is produced. Environmental protection damping materials have the following performance characteristics:

Environmental friendly, non-toxic, high efficient damping, high flame-retardant, wide temperature range, excellent mechanical properties and convenient construction.

Environmental damping noise reduction materials can be used in bus body and floor, small car door and floor, high-speed train body, intercity train body, subway, light rail body and other parts to achieve damping vibration reduction and achieve the purpose of high-efficiency noise reduction.
