Excellent damping can be obtained in the wide wide environment with temperature；In addition, according to the adhesion properties of damping material, pressure sensitive adhesive can be divided into
Two kinds of type and rubber (plasticity) piece type, it is in the prior art that its bonding characteristic and adhesive structure combination is not good, therefore its damping effect
Can be without very big lifting.
Utility model content
For the drawbacks described above and problem of prior art, the purpose of the utility model embodiment is to provide a kind of NEW TYPE OF COMPOSITE
Damping sheet, composite damping board of the present utility model is a kind of NEW TYPE OF COMPOSITE damping sheet developed exclusively for aircraft industry, by constraining
The compound composite damping layer constituted of the damping layer of layer and different-thickness, its temperature in use and frequency effect scope are wider, vibration and noise reducing effect
More preferably, the damping sheet solved in the prior art for aircraft industry can not be in different frequency ranges with that can be obtained in warm wide environment for fruit
The problems such as obtaining excellent damping.
In order to achieve the above object, the utility model provides following technical scheme：
A kind of NEW TYPE OF COMPOSITE damping sheet of the present utility model, including restraint layer and damping layer；Wherein, the one of the restraint layer
Damping layer described in multilayer is pasted in face superposition.
Further, the multilayer damping layer includes the first damping layer and the second damping layer；The thickness of the damping layer is
0.5-0.8mm。
Preferably, the thickness of the damping layer is 0.5-0.6mm.
Further, also institute is passed through between the restraint layer, the first damping layer and the second damping layer including organic tack coat
State organic adhesive layer stickup.
Further, the restraint layer is aluminum sheet material, wherein, the thickness of the restraint layer is 0.1-0.2mm.
Preferably, the thickness of the restraint layer is 0.15mm.
Further, the organic adhesive thickness degree between the restraint layer and the first damping layer is 0.1-0.15mm；It is described
Organic adhesive thickness degree between first damping layer and the second damping layer is 0.2-0.25mm.
Preferably, the organic adhesive thickness degree between the restraint layer and the first damping layer is 0.15mm；First resistance
Organic adhesive thickness degree between Buddhist nun's layer and the second damping layer is 0.25mm.
Further, the organic adhesive layer is acrylic resin films layer.
Further, also including bottom organic adhesive layer, the bottom organic adhesive layer is pasted onto second damping layer
Another side；Wherein, the thickness of the bottom organic adhesive layer is 0.25-0.3mm.
Preferably, the thickness of the bottom organic adhesive layer is 0.25mm.
Further, the damping layer is mixed by macromolecule resin, graphite and inorganic filler.
The utility model provide a kind of NEW TYPE OF COMPOSITE damping sheet, avoided from material type selecting it is traditional using rubber as
The technique of main damping body, but macromolecule resin is selected as damping material main body, to strengthen the elasticity of damping material in itself
Modulus, while being aided with soft graphite and other inorganic fillers, so that damping layer forms high elastic modulus but with corresponding viscous
The high-effect damping layer of elasticity.Meanwhile, as damping layer overall structure, the utility model devises multiple-effect damping material and is combined work
Skill, is additionally arranged between multilayer damping layer and restraint layer respectively from the organic adhesive layer of different-thickness, makes it have different frequency effects,
So as to form the composite damping material structure of structure and damping function integration.Make damping layer in the wide environment of different frequency ranges and temperature
In can obtain excellent damping, damping of the present utility model is higher than 75%.Simultaneously as having used substantial amounts of nothing
Machine damping material so that damping layer overall flame excellent performance, high and low temperature resistance has also obtained great lifting, and this practicality
New is full resin system, without any asphalt component, and unharmful substance, which overflows, to be dissipated, and frequency model wide (200HZ-2000HZ), Wen Fan
Wide (- 50 DEG C+120 DEG C), effect of vibration and noise reduction is more preferable.
