On, the noise that compressor of air conditioner issues will seem especially noisy, the especially noise of low-frequency range, and human body sensory is uncomfortable
Main source can seriously affect the sleep of people.
Compressor is the major source that air-conditioner outdoor unit generates noise, in order to reduce the noise that compressor gives off, is commonly used
Measure is to coat sound-proof material in compressor surrounding.Common sound-proof material is generally made of single layer sound-absorbing material and single layer sound insulating material,
Expected effect is often not achieved in its sound absorbing performance, especially to the absorption of low-frequency noise.It makes an uproar to improve to compressor radiation
The absorbability of sound needs to consider that the superposition of multiple-layer absorbers uses.
To solve the problems, such as that Conventional acoustical insulation cotton sound absorption effect is poor, Chinese utility model patent CN201671793U discloses one
Kind sound-proof material, as shown in Figure 1, it is by fire-retardant nonwoven fibre layers 6, rubber pange layer 7, calendering soft rubber layer 8, plastic foamed layer
9, the superposition of vulcanie 10 composition, can be improved the absorption to low frequency range noise, especially frequency is between 125Hz~500Hz
Noise；Chinese utility model patent CN201747557U discloses a kind of sound-proof material, as shown in Fig. 2, it is by fire-retardant non-woven fibre
Layer 6 ', hard rubber layers 7 ', rubber-plastic foamed layer 8 ' superposition composition, the absorbability of centering band noise are more excellent.However it is this every
The sound-absorbing material of sound cotton is too single, and sound-absorbing material overlay order influences not plus illustrates on sound absorbing performance, and absorb sound optimal frequency range phase
To relatively narrow.

Further, the sound-absorbing material is fire-retardant felt, fiber, polyurethane cotton, PU foaming etc..The sound insulating material is
Rubber, PVC etc..
Further, every layer of sound-absorbing material is with a thickness of 4~15mm, and every layer of sound insulating material is with a thickness of 1~3mm.
Further, the sound-absorbing material layer passes through, and the suture of all sound-absorbing material sutures is made, the sound-absorbing material
Layer volume density is maximum or porosity is minimum or flow resistance is maximum or maximum one layer of structure factor cemented together with sound insulating material layer.
Further, the suture is enclosed in the edge of sound-absorbing material layer suture one, and at the center of sound-absorbing material layer
The suture of at one or a few places.
Further, the side of the sound-absorbing material layer of the sound-proof material is towards noise source.
Further, the sound-absorbing material layer includes three layers of sound-absorbing material layer.
The utility model also provides a kind of compressor, and the surrounding of the compressor is coated with above-mentioned sound-proof material.
The utility model is the sound-proof material device that a kind of a variety of sound-absorbing materials of compressor outer cladding are superimposed, and the purpose is to most
Absorb the noise that compressor is radiate to big degree.The sound-proof material can be also used for other devices or occasion for needing sound insulation.
The lamination order of multiple-layer absorbers is compared with other lamination orders in the utility model, with higher sound absorption
Coefficient, i.e., it is more preferable to the absorbability of noise.For sound-absorbing material, bulk density is the ratio between quality and material total volume；
Porosity refers to the ratio between material internal volume of air and material total volume；Flow resistance refers to that air particle passes through the resistance in material void
Power is characterized as the gas permeability of material；Structure factor is used to describe the shape of slight gap and the complexity arranged in material and does not advise
Then degree.These parameters are not independent, connect each other.In practice, the bulk density of material is big, porosity generally compared with
Small, flow resistance and structure factor are larger.Sound-absorbing material overlay order is changed from small to big for bulk density, and (correspondingly porosity is by becoming greatly
Small, flow resistance and structure factor change from small to big), wherein the biggish absorbent treatment of bulk density and sound insulating material (such as rubber layer PVC) phase
It is coupled.This structure can be realized the sound-proof material while the efficient absorption of high and low frequency noise, and have higher suction
Sonic system number is more conducive to reduce noise.
The utility model has the following beneficial effects:
1, material source is wide, and structure is simple, easy to process, and applicability is extensive；
2, there is higher acoustic absorptivity, be more conducive to the absorption of noise, noise especially wider to frequency range has very
Good noise reduction effect.
