Abstract
The utility model discloses a composite damping board based on reclaimed rubber base member, including bottom and damping layer, the bottom is the steel sheet, the damping layer is modified reclaimed rubber, the steel sheet if modified reclaimed rubber only simultaneously adheres, steel sheet and modified reclaimed rubber form free damping layer structure, the steel sheet if all adhere in modified reclaimed rubber two sides, two blocks of steel sheets and modified reclaimed rubber form restraint damping layer structure, produce the effect of coincideing for avoiding in same frequency range, and two steel sheet thickness are different, the utility model discloses simple structure uses multipurposely the high defening effect of steel sheet and utilizes modified reclaimed rubber material to form big damping restraining structure layer and restrain the easy resonant performance of steel sheet, will reduce more than 90% through the noise energy of sound insulation board, damping material adopts modified reclaimed rubber, can reduce the material cost of damping sheet on the one hand, pollution that on the other hand can greatly reduced abandonment rubber causes the environment.
Description
Technical field
The utility model relates to the material, particularly a kind of composite damping board based on reclaimed rubber matrix that utilize vibration control to reduce radiated noise and carry out insulating against sound.
Background technology
Conventional damping sound-insulation board is the sound insulationg board for buildings substantially, and its structure is shown in accompanying drawing 3, and it is combined by gluing way by materials such as magnesite board (or plasterboard) 5, sound insulation damping felt 6 and cement plates.It is not suitable for the sound insulation of machinery and equipment.The sound insulation of current machinery and equipment is mainly pasted onto on noise radiation face with the asphaltic base sound-insulating felt of different-thickness by gluing way, and the oise insulation factor of this method is little, and the viscose glue of sound-insulating felt can be made to come off due to the vibration of machinery and equipment, thus sound insulation was lost efficacy.The composite damping board that another kind is usually used in machinery and equipment sound insulation is brushing asbestos paint between two-layer substrate, and owing to requiring that the thickness of asbestos paint is greater than the thickness of 2 times of plates, therefore brushing asbestos paint is a very troublesome thing.In addition, this structure is owing to using viscous-elastic material, and adhesion is less, when operations such as bending, distortion, welding or punching presses, all must take corresponding strengthening measure.
Utility model content
In order to overcome the deficiency of existing damping sound-insulation board in performance and manufacture etc., a kind of composite damping board based on reclaimed rubber matrix is proposed.
The purpose of this utility model can be achieved through the following technical solutions:
Based on a composite damping board for reclaimed rubber matrix, comprise bottom and damping layer, described bottom is steel plate, and described damping layer is modification regeneration rubber, and described steel plate and reclaimed rubber form free damping layer structure.
Based on a composite damping board for reclaimed rubber matrix, comprise two bottoms of damping layer and clamping damping layer, described bottom is steel plate, and described damping layer is modification regeneration rubber, and described two block plates and modification regeneration rubber form damping-constraining Rotating fields.
Further, described two block plate thickness are different, the coincidence frequency of steel plate is staggered, avoids producing coincidence effect in same frequency range.
Further, the thickness of described steel plate and the thickness of modification regeneration rubber can adjust according to sound insulation requirement.
Further, on described steel plate, the difform emboss pit of punching press forms reinforcement, to increase the rigidity of steel plate further.
The beneficial effects of the utility model: fully utilize the high defening effect of steel plate and utilize modification regeneration elastomeric material to form large damper restriction structural sheet to the performance suppressing steel plate to be easy to resonance, the noise energy through sound insulationg board is reduced by more than 90%.When being delivered to the side of sound insulationg board at sound wave, steel plate is subject to excitation and starts vibration, modification regeneration elastomeric material in the middle of palette can stand the vibration of extrusion stress and shear stress obstruction steel plate under the effect of shear stress, in this case, damping material in interlayer can suppress the vibration of steel plate effectively, and become thermal energy consumption to dissipate the changes mechanical energy of sound wave, thus significantly improve soundproof effect; Because damping material adopts reclaimed rubber, the material cost of damping sheet can be reduced on the one hand, can greatly reduce waste rubber pollution on the environment on the other hand.
