VIBRATION DAMPING BLOCK Russian patent published in 2015 - IPC B32B7/10 E04B1/84 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry machine building, construction and etc. where effective lowering of engineering structures vibrations and engine noise is required and concerns vibration damping block. The block contains one or more foil plates and connected with it layers of polymeric compound including synthetic rubber, plasticizer and fillers. Polymeric compound additionally contains asphalt, modified epoxide resin, stearine and mixture of modified bergmeal with talc in 1:4 relation, and as filler it contains chalk stone, zinc oxide and carbon black with corresponding relation of components. Foil plates thickness is 0.1-0.3 mm. Polymeric compound having thickness of 1.0-2.0 mm is protected from outer side by antiadhesion coating.

EFFECT: invention permits to improve efficiency of vibration absorbing properties in the range of -20 to +60°C, to simplify material mounting on various coatings, to reduce block mass.
