Abstract
It the utility model is related to technical field of automobile accessories, more particularly to a kind of shock absorption sound deadening sheet.By setting gradually flame-retardant sponge layer, foaming rubber layer, encryption spongy layer, sound-absorbing spongy layer and pressure-sensitive adhesive layer from top to bottom；The encryption spongy layer center is provided with sound-absorbing groove；Make a kind of shock absorption sound deadening sheet sound insulation and good flame retardation effect.
Description
Technical field
It the utility model is related to technical field of automobile accessories, more particularly to a kind of shock absorption sound deadening sheet.
Background technology
Shock absorption sound deadening sheet is a kind of viscoelastic material for being attached to vehicle body inner surface, is close on the steel plate wall of vehicle body, mainly
It is to play a part of reducing noise, reduce vibrations, that is to say, that play damping action；Current shock absorption sound deadening sheet sound insulation and
Flame retardant effect is not fine.
Utility model content
The purpose of this utility model is to provide a kind of shock absorption sound deadening sheet of sound insulation and good flame retardation effect.
The technical solution of the utility model is as follows：
A kind of shock absorption sound deadening sheet, it is characterised in that set gradually flame-retardant sponge layer, foaming rubber layer, encryption from top to bottom
Spongy layer, sound-absorbing spongy layer and pressure-sensitive adhesive layer；The encryption spongy layer center is provided with sound-absorbing groove.
The sound-absorbing groove undulate.Due to sound-absorbing groove undulate, it can effectively strengthen sound-absorbing effect.
The equal indention ripple in the upper and lower side of sound-absorbing groove.Due to the equal indention in upper and lower side of sound-absorbing groove
Ripple, wedge angle is all so formd on the upper side edge and lower side of sound-absorbing groove, sound wave can be allowed in the upper and lower of sound-absorbing groove
Fully absorbed on side, strengthen sound-absorbing effect.
The zigzag ripple is made up of some continuous sawtooth, the sawtooth include the first tilting section, the second tilting section and
Connect the flat segments of first, second tilting section.Zigzag wave uses this similar trapezoidal structure, and sound-absorbing effect is more preferable.
The beneficial effects of the utility model are：Due to being flame-retardant sponge layer in outermost layer, fire-retardant effect, energy are primarily served
It is enough effectively to avoid the sponge of lower floor from damaging；Coordinated by foaming rubber layer and encryption spongy layer, improve damping effect；Pass through setting
Sound-absorbing spongy layer, play the effect of sound insulation, noise reduction；By setting pressure-sensitive adhesive layer, it is easy to the installation of shock absorption sound deadening sheet；By setting
Sound-absorbing groove is put, not only the sound-absorbing effect of enhancing encryption spongy layer, coordinates sound-absorbing spongy layer, greatly strengthen shock absorption sound deadening sheet
Silencing function, and enhance buffering effect.
Brief description of the drawings
By detailed description below in conjunction with the accompanying drawings, the foregoing and other objects, features and advantages of the utility model will
Become apparent.
Wherein：Fig. 1 is the structural representation of the utility model embodiment 1；
Fig. 2 is the structural representation of the utility model embodiment 2；
In accompanying drawing, 1 is flame-retardant sponge layer, and 2 be foaming rubber layer, and 3 be encryption spongy layer, and 4 be sound-absorbing spongy layer, and 5 be pressure
Quick glue-line, 6 be sound-absorbing groove, and 7 be the first tilting section, and 8 be the second tilting section, and 9 be flat segments.
Embodiment
Referring to shown in Fig. 1-Fig. 2, a kind of shock absorption sound deadening sheet, it is characterised in that set gradually flame-retardant sponge layer from top to bottom
1st, foaming rubber layer 2, encryption spongy layer 3, sound-absorbing spongy layer 4 and pressure-sensitive adhesive layer 5；The encryption spongy layer center is provided with sound-absorbing
Groove 6.Due to being flame-retardant sponge layer in outermost layer, fire-retardant effect is primarily served, can effectively avoid the sponge of lower floor from damaging；
Coordinated by foaming rubber layer and encryption spongy layer, improve damping effect；By setting sound-absorbing spongy layer, sound insulation, noise reduction are played
Effect；By setting pressure-sensitive adhesive layer, it is easy to the installation of shock absorption sound deadening sheet；By setting sound-absorbing groove, not only enhancing encryption
The sound-absorbing effect of spongy layer, coordinate sound-absorbing spongy layer, greatly strengthen the silencing function of shock absorption sound deadening sheet, and enhance buffering
Effect.
The sound-absorbing groove undulate.Due to sound-absorbing groove undulate, it can effectively strengthen sound-absorbing effect.May be used also
To fill in acoustical cotton in sound-absorbing groove, to improve sound-absorbing effect.
The equal indention ripple in the upper and lower side of sound-absorbing groove.Due to the equal indention in upper and lower side of sound-absorbing groove
Ripple, wedge angle is all so formd on the upper side edge and lower side of sound-absorbing groove, sound wave can be allowed in the upper and lower of sound-absorbing groove
Fully absorbed on side, strengthen sound-absorbing effect.Acoustical cotton can also be filled in sound-absorbing groove, to improve sound-absorbing effect.
The zigzag ripple is made up of some continuous sawtooth, and the sawtooth includes the first tilting section 7, the second tilting section 8
With the flat segments 9 of first, second tilting section of connection.Zigzag wave uses this similar trapezoidal structure, and sound-absorbing effect is more preferable.
The flame-retardant sponge layer top surface is coated with aerogel heat-proof coating.Due to aerogel heat-proof coating have preferably every
Thermal effect and preferable anticorrosion effect, the service life of shock absorption sound deadening sheet is greatly prolonged, and strengthen fire resistance.
It is described above, only it is preferred embodiment of the present utility model, any formal limit is not done to the utility model
System, it is every according to any simple modification made in the technical essence of the utility model to above example, equivalent variations, fall
Enter within the scope of protection of the utility model.
