Abstract

The utility model relates to an inhale sound sponge technical field, especially relate to inhale sound sponge from skinning. Through the sponge layer, be equipped with the protection film outside this sponge layer, be equipped with on the bonding face of protection film one side and paste the layer, be provided with on the another side from the skinning rete, inhaling sound sponge central authorities and being provided with the cavity, it has the sound of the inhaling part that takes precautions against earthquakes to bond in this cavity, inhale right another of sound sponge and bonding facial features and personally submit the wave type, it is firm to make inhale sound sponge from skinning bond, and non -deformable.

Description

From skinning sound-absorbing sponge
Technical field
The utility model relates to sound-absorbing sponge technical field, particularly relates to from skinning sound-absorbing sponge.
Background technology
Sound-absorbing foam is also known as acoustical material or sound-absorbing sponge etc., and sound-absorbing foam adopts PU, the perforate PE, perforate EPDM or perforate NBR etc. of excellent performance to be primary raw material, is equipped with various high-quality auxiliary material, the sound-absorbing foam material made through high temperature mixed foaming; Current sound-absorbing foam when stressed larger, easily deform, after distortion, sound-absorbing effect is poor, and is generally bonded in the position needing sound insulation by bonding mode due to sound-absorbing sponge, after long-time, easily comes unstuck.
Utility model content
The purpose of this utility model is to provide a kind of firmly bonding, and on-deformable from skinning sound-absorbing sponge.The technical solution of the utility model is as follows:
From skinning sound-absorbing sponge, comprise spongy layer, be provided with diaphragm outside this spongy layer, the bonding plane of diaphragm side is provided with adhered layer, another side is provided with from skinning rete; Described sound-absorbing sponge central authorities are provided with cavity, are bonded with sound-absorbing shock-resistant member in this cavity; The another side that described sound-absorbing sponge is relative with bonding plane is undaform.
Described adhered layer adopts environmental protection glue-line.Owing to adopting environment-friendlyadhesive adhesive, environment-friendlyadhesive adhesive is torn by the user that is more convenient for, not trace, and the feature of environmental protection is higher.
Described sound-absorbing shock-resistant member adopts acoustical cotton block, and this acoustical cotton block is formed continuously by some sponge strips of ellipse.Because the surface of contact of acoustical cotton block and sound-absorbing sponge is all in circular arc, arc-shaped structure is more firm, can effectively increase the service life at the sound-absorbing effect strengthening sound-absorbing sponge simultaneously.
Described sound-absorbing shock-resistant member adopts air bag.Owing to being full of air in air bag, therefore it is shockproof all very good with effect that is sound insulation, by inserting air bag in attraction sponge, can increase sound-absorbing effect further.
The sponge aperture of described spongy layer is 45PPI-55PPI.Due to when sponge aperture is between 45PPI-55PPI, the microporosity of sponge is better, can the energy of effective attenuation sound wave.
The beneficial effects of the utility model are: by arranging diaphragm, on the one hand can spongy layer inside available protecting, and on the other hand when bonding, diaphragm and adhered layer use together and bonding persistence can be made better, not easily drop; Make sound-absorbing effect better by arranging from skinning rete; By arranging sound-absorbing shock-resistant member, strengthen the serviceable life of sound-absorbing effect and sound-absorbing sponge further.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the utility model will become apparent.
Wherein: Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model acoustical cotton block structure schematic diagram;
In accompanying drawing, 1 is spongy layer, and 2 is diaphragm, and 3 is adhered layer, and 4 is from skinning rete, and 5 is cavity, and 6 is acoustical cotton block, and 7 is sponge strip, and 8 is air bag.
Embodiment
Shown in Fig. 1-Fig. 2, from skinning sound-absorbing sponge, comprise spongy layer, be provided with diaphragm outside this spongy layer, the bonding plane of diaphragm side is provided with adhered layer, another side is provided with from skinning rete; Described sound-absorbing sponge central authorities are provided with cavity, are bonded with sound-absorbing shock-resistant member in this cavity; The another side that described sound-absorbing sponge is relative with bonding plane is undaform.By arranging diaphragm, on the one hand can spongy layer inside available protecting, on the other hand when bonding, diaphragm and adhered layer use together and bonding persistence can be made better, not easily drop; Make sound-absorbing effect better by arranging from skinning rete; By arranging sound-absorbing shock-resistant member, strengthen the serviceable life of sound-absorbing effect and sound-absorbing sponge further.
Preferably, described adhered layer adopts environmental protection glue-line.Owing to adopting environment-friendlyadhesive adhesive, environment-friendlyadhesive adhesive is torn by the user that is more convenient for, not trace, and the feature of environmental protection is higher.
Preferably, described sound-absorbing shock-resistant member adopts acoustical cotton block, and this acoustical cotton block is formed continuously by some sponge strips of ellipse.Because the surface of contact of acoustical cotton block and sound-absorbing sponge is all in circular arc, arc-shaped structure is more firm, can effectively increase the service life at the sound-absorbing effect strengthening sound-absorbing sponge simultaneously.
Preferably, described sound-absorbing shock-resistant member adopts air bag.Owing to being full of air in air bag, therefore it is shockproof all very good with effect that is sound insulation, by inserting air bag in attraction sponge, can increase sound-absorbing effect further.
Preferably, the sponge aperture of described spongy layer is 45PPI-55PPI.Due to when sponge aperture is between 45PPI-55PPI, the microporosity of sponge is better, can the energy of effective attenuation sound wave.
Preferably, described spongy layer adopts polyurethane sponge.Production cost is low, and sound-absorbing effect is good.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model, every according in technical spirit of the present utility model to any simple modification, equivalent variations that above embodiment is done, all fall within protection domain of the present utility model.
