Abstract
The utility model relates to a sound damping material, in particular to a sound damping cotton for air conditioner compressor. The utility model is intended to resolve the defects in existing technology and provide a sound damping cotton for lowering or eliminating low frequency noise. The technical proposal of the utility model is: the sound damping cotton is composed of a sound absorption cotton layer and a rubber board layer. The utility model is characterized in that: the sound damping cotton also comprises an aluminum foil. With the adoption of the technical proposal for the utility model, the low frequency noise can be effectively reduced or eliminated, so as to greatly reduce the peak value of noise. The utility model can realize excellent filtration effect for the low frequency noise within the range of 100Hz-450Hz, improve the reduction of high frequency noise and outstandingly improve the sound quality of the whole machine.
Description
Technical field
The utility model relates to a kind of acoustic material, especially, relates to the Sound-proof material that a kind of compressor of air conditioner is used.
Background technology
In existing small air-conditioning system, the running noise of compressor of air conditioner is bigger; In order to reduce the noise of cooler compressor, the engineer generally solves noise problem by aspects such as resonance analyzing and system matches; When above-mentioned means all can not be gathered effect, just use Sound-proof material parcel compressor, solve the noise of cooler compressor by the method that absorbs sound wave and isolated sound wave unofficial biography.In the prior art, the main composition of the Sound-proof material of compressor of air conditioner is: individual layer retardant cotton+rubber slab (shown in Figure 1A) or individual layer retardant cotton+rubber slab+individual layer retardant cotton+rubber slab (shown in Figure 1B), these two kinds of Sound-proof materials can both act on basically to some extent to high frequency noise, but low frequency noise is not particularly had filtration at 100HZ to the low frequency noise in the 450HZ scope.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of Sound-proof material that can reduce or eliminate low frequency noise is provided.
The technical solution of the utility model is: a kind of Sound-proof material comprises acoustical cotton layer, rubber flaggy; It is characterized in that described Sound-proof material also comprises aluminium foil layer.
Adopt the technical solution of the utility model to effectively reduce or eliminate low frequency noise, the low frequency noise peak value is significantly reduced.Particularly obvious especially to the low frequency noise filtration in the 450HZ scope to low frequency noise at 100HZ.

The specific embodiment
First embodiment
Fig. 2 is the structural representation of the utility model embodiment one; As shown in Figure 2, a kind of Sound-proof material is made of trilaminate material, comprises acoustical cotton layer 1, rubber flaggy 2 and aluminium foil layer 3.Described rubber flaggy 2 is clipped between described acoustical cotton layer 1 and the described aluminium foil layer 3.Described acoustical cotton layer 1 main material is flame retardant fiber.Described rubber flaggy 2 main materials are anti-flammability rubber damping plate, and what use morely is neoprene rubber sheet and butyl rubber sheet.Be connected with super glue by rubber tack between each layer.In order to guarantee the effectiveness of described Sound-proof material, the thickness between each layer of Sound-proof material also there is certain requirement; Aluminium foil layer thickness is more than or equal to 0.5mm; The rubber slab layer thickness is more than or equal to 1mm.
Second embodiment
The difference of the utility model and first embodiment is that described aluminium foil layer 3 is clipped between described acoustical cotton layer 1 and the described rubber flaggy 2.
The 3rd embodiment
Fig. 3 is the structural representation of the utility model embodiment three; The difference of the utility model and first embodiment is that this Sound-proof material is made of five layer materials altogether, described rubber flaggy 2 and described acoustical cotton layer 1 arranged crosswise, and the innermost layer is described acoustical cotton layer 1; Arrange described aluminium foil layer 3 at outermost layer again.
Embodiment of the present utility model in fact can also be other, can unconfinedly increase as the number of plies of Sound-proof material, and the material arrangements of each layer also is can conversion; But consider to be difficult for too thick from the cost aspect.
Fig. 4 is the spectrogram behind use the utility model embodiment one described Sound-proof material; Fig. 5 is the spectrogram behind the described Sound-proof material of use prior art; Contrast two spectrograms, we are not difficult to find to adopt the Sound-proof material of technical solutions of the utility model, and are particularly obvious especially to the low frequency noise filtration in the 450HZ scope at 100HZ to low frequency noise; And high frequency noise also made moderate progress; Complete machine tonequality has clear improvement.Testing background is in the drawings: refrigerating capacity is that 7000W, input power 2500W, rotation speed of fan are 840rpm; Frequency is that the low frequency noise peak value at 104HZ place significantly reduces in the drawings, is reduced to 43.8 decibels by original 47.2 decibels.
