Abstract
The utility model discloses an acoustic decorative board, including perforation glass magnesium board, centrifugal glass cotton and glass silk cloth, the cotton subsides of centrifugal glass is covered in perforation glass magnesium inboard side, and glass silk applique pieces attach on perforation glass magnesium board outside surface. This acoustic decorative board, fatigue strength is high, has the decoration effect simultaneously.
Description
Technical field
The utility model relates to ornament materials, particularly to a kind of sound absorption decorative plate.
Background technology
Along with improving constantly of people's living standard, residing acoustic enviroment is required more and more higher.At present,
The vehicles and highway, railway, machinery etc. are noise generated very big to surrounding environment influence, solve
Method be to be applied in cavity, with flexible polyurethane foams, the sound-absorbing that foams, sound-absorbing effect is preferable, but by force
Spend low, there is no decoration function.
The information being disclosed in this background section is merely intended to increase general background of the present utility model
Understand, and be not construed as recognizing or imply in any form that this information structure is for the general skill in this area
Prior art well known to art personnel.
Utility model content
The purpose of this utility model is to provide a kind of sound absorption decorative plate, and shock strength is high, has dress simultaneously
Decorations effect.
For achieving the above object, the utility model provides a kind of sound absorption decorative plate, including perforation glass magnesium board,
Centrifugally glass-wool and glass wool cloth, centrifugally glass-wool is covered in inside perforation glass magnesium board, and glass wool cloth attaches
At perforation glass magnesium board outer surface.
Compared with prior art, the utility model has the advantages that the structure of this sound absorption decorative plate
Being made up of perforation glass magnesium board, centrifugally glass-wool and glass wool cloth, antidetonation earthquake intensity reaches 9 grades, sqouynd absorption lowering noise
Index is higher, and finish coat has decorative effect, can draw different pattern and textured pattern as requested.
Accompanying drawing explanation
Fig. 1 is the structural representation according to sound absorption decorative plate of the present utility model；
Fig. 2 is the schematic perspective view according to sound absorption decorative plate of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described in detail, but it should reason
Solve protection domain of the present utility model not limited by detailed description of the invention.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " bag
Include " or its conversion as " comprising " or " including " etc. will be understood to comprise stated element or
Part, and do not get rid of other element or other part.
As shown in Figure 1 to Figure 2, according to a kind of sound absorption decorative plate of the utility model detailed description of the invention,
Including perforation glass magnesium board 1, centrifugally glass-wool 2 and glass wool cloth 3, wherein centrifugally glass-wool 2 is covered in and wears
The inner side of hole glass magnesium board 1, glass wool cloth 3 is attached to perforation glass magnesium board 1 outer surface.
In such scheme, the glass magnesium board of composition sound absorption decorative plate, lightweight, high with specific strength, antidetonation is strong
Degree reaches 9 grades, improves insulation, fire resistance, and sound-absorbing frequency is wide, easy for installation.According to different frequencies
Rate, the thickness of percent opening and perforated plate by adjusting perforation glass magnesium board (during construction, fill out by mainly inside
The thickness filling centrifugally glass-wool determines acoustically effective), the noise reduction requirement that client is different can be realized.Rotary glass
Gossypium, in sound-absorbing porous material, has good sound absorbing capabilities, it is possible to the reason of sound absorption is primarily due to tool
There is the micro-pore hole of substantial amounts of inside and outside connection.When on sound wave incident to centrifugally glass-wool, sound wave energy
Enough enter material internal along hole, cause the vibration of air molecule in hole, owing to the viscous of air hinders
The friction of power and air molecule and pore wall, acoustic energy is converted into heat energy and is lost.Noise reduction coefficient can reach 0.85
Above.It addition, glass wool cloth 3 is as architectural surface, different pattern and texture can be drawn as requested
Pattern, has decorative effect.Thering is provided a kind of sound absorption decorative plate, sqouynd absorption lowering noise index is preferable；
To sum up, the sound absorption decorative plate of the present embodiment, structure is by glass magnesium board of boring a hole, centrifugally glass-wool and glass
Silk cloth composition, antidetonation earthquake intensity reaches 9 grades, and sqouynd absorption lowering noise index is higher, and finish coat has decorative effect,
Different pattern and textured pattern can be drawn as requested.
The aforementioned description to specific illustrative embodiment of the present utility model illustrates that and the mesh of illustration
's.These describe and are not wishing to be defined to the utility model disclosed precise forms, and it will be apparent that
According to above-mentioned teaching, can much change and change.Exemplary embodiment is selected and describes
Purpose be to explain certain principles of the present utility model and actual application thereof, so that the skill of this area
Art personnel be capable of and utilize various different exemplary of the present utility model and various not
Same selection and change.Scope of the present utility model is intended to be limited by claims and equivalents thereof.
