Abstract
A sound absorption noise lowering board belongs to the technical field of sound absorption and noise reduction material used in passenger train. The viscoelastic body of the sound absorption and noise reduction material is covered on the flexible lining forming a layer structure; the viscoelastic body made of polymer acrylic acid adhesive tape, namely, HIP2, and flexible linin is made of aluminum sheet with high magnesium content. The utility model provides a sound absorption and noise reduction material with light weight and good noise reduction effect on passenger train and light rail vehicles, having the advantages of convenient operation and low labor intensity, and being in convenient for occupational health and environmental protection.
Description
Technical field
The utility model belongs to the absorbing sound and lowering noise material technology field that passenger train is used, and is specifically related to a kind of absorbing sound and lowering noise plate.
Background technology
What at present, the absorbing sound and lowering noise of passenger train adopted is in passenger car internal spray acoustic damping materials---the mode of damping slurry or damping paint.The Main Ingredients and Appearance of damping slurry and damping paint is respectively pitch and polyurethane, and operation then must be used the lance driving device spraying.Need spray thicker coating for improving noise reduction, the weight of coating also can increase thereupon, but noise reduction is very limited, and is also influential to train speed raising; Labour intensity is big in spraying operation, and the operator is had employment injuries and environment is polluted.
Summary of the invention
The purpose of this utility model is exactly that a kind of light weight excellent noise reduction effect again that is used on passenger train and the light rail vehicle will be provided, and uses easy to operately, and labour intensity is low, helps the absorbing sound and lowering noise material of occupational health and environmental protection, to overcome the defective of prior art.
The technical solution adopted in the utility model is absorbing sound and lowering noise material viscoelastic body to be covered on flexible lining quilt form laminar texture.
More particularly, viscoelastic body adopts the poly-mer acrylic adhesive tape, i.e. HIP2, and flexible lining is used the high aluminium sheet of content of magnesium.
During use, with the utility model directly cover on the base plate of train, below the end chair, on the door inner panel, the shell of motor etc. easily produces on the parts of noise, can reduce noise.
The various combination of the thickness by regulating viscoelastic body and flexible lining quilt can reduce the noise of different frequency targetedly.
Good effect of the present utility model is:
1, light weight, noise reduction is unusual, reduces sonorant, improves the class of passenger vehicle, for the passenger provides comfortable environment by bus, can fully satisfy reducing the design that noise has high requirements.
2, use is easy to operate, and labour intensity is low, only needs the absorbing sound and lowering noise plate directly is attached on the parts that will reduce noise on the passenger vehicle, gets final product noise reduction.
3, help occupational health and environmental protection, unharmful substance and bad working environment in manipulating.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing.
Embodiment 1:
See Fig. 1, lining is adopted the high aluminium sheet of content of magnesium by 1, thickness is 0.5mm, viscoelastic body 2 adopts the poly-mer acrylic adhesive tape, be HIP2, thickness can adopt 0.05mm, 0.13mm and 0.25mm respectively, the poly-mer acrylic adhesive tape is covered the sheet material that forms laminar texture on the high aluminium sheet of content of magnesium, make the blank of required size and stick the craft paper lining paper in poly-mer acrylic adhesive tape one side by user's requirement.Be cut into required form in the erecting stage, tear the craft paper lining paper off, be bonded on the passenger car and need get final product on the parts of noise reduction.
Embodiment 2:
See Fig. 1, lining is adopted the high aluminium sheet of content of magnesium by 1, and thickness is 1.0mm, and viscoelastic body 2 adopts the poly-mer acrylic adhesive tape, i.e. HIP2, and thickness can be respectively 0.05mm, 0.13mm, 0.25mm and 0.5mm.With the lower part with embodiment 1.
Claims (2)
1, a kind of absorbing sound and lowering noise plate comprises the absorbing sound and lowering noise material, it is characterized in that: absorbing sound and lowering noise material viscoelastic body (2) covers at flexible lining and is gone up the composition laminar texture by (1).
2, absorbing sound and lowering noise plate as claimed in claim 1 is characterized in that: described viscoelastic body (2) is the poly-mer acrylic adhesive tape, i.e. HIP2, and flexible lining is the high aluminium sheet of content of magnesium by (1).
