Description
Technical Field
The utility model relates to the field of decorative plates, in particular to a light-weight sound-absorbing decorative plate.
Background
The decorative board is an artificial board, and is a thermosetting laminated plastic made of various special papers through chemical treatment and high-temperature and high-pressure adhesive, and the surface of the decorative board has various wood grains or patterns, is bright and flat, and is bright and beautiful in color and luster, and simultaneously has high wear-resisting, heat-resisting, cold-resisting, fireproof and other good physical properties. However, the existing decorative plate is of a solid structure, is heavy and does not have the sound absorption function.
Although decorative boards with sound absorption function are also available in the market, for example, a side-hole ultra-light inorganic fiber composite decorative board disclosed in prior art 201922075670.0 is formed by compounding five layers of materials, wherein the first layer is an appearance fabric decorative layer, the second layer is an adhesive glue film layer, the third layer is a sound absorption layer, an inorganic fiber felt is adopted, the fourth layer is an adhesive PE glue film layer, and the fifth layer is an aramid fiber/polypropylene protective layer; because the decorative board number of piles is too many, not only leads to the decorative board heavier, and has increased manufacturing cost to the sound absorbing layer is wrapped up by multilayer material, leads to the sound absorbing effect poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a light-weight sound-absorbing decorative plate for overcoming the defects of the prior art.
In order to achieve the purpose, the utility model adopts the technical scheme that: a light-weight sound-absorbing decorative plate comprises a plate body and decorative layers respectively arranged on the surface of the plate body; the plate body is of a hollow structure, and special-shaped porous fibers are filled in the plate body; the face of the plate body is provided with a plurality of through holes communicated with the inside of the plate body respectively.
Preferably, the surface of the shaped porous fiber is gear-shaped.
Preferably, the shaped porous fiber is in a porous honeycomb shape.
Preferably, the profiled porous fiber is a four-hole, seven-hole or nine-hole hollow polyester fiber.
Preferably, the titer of the profiled porous fiber is between 6.67 dtex and 16.67 dtex.
Preferably, a plurality of reinforcing ribs which are arranged in a criss-cross mode are arranged inside the plate body.
Preferably, the decorative layer is fixedly connected with the surface of the plate body in an adhesion mode.
Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
1. the utility model has less layers, and compared with the fiber with the same thickness, the utility model can lighten by more than 50 percent by filling the special-shaped porous fiber in the plate body, thereby greatly reducing the weight of the decorative plate, realizing the light weight and reducing the production cost;
2. the plurality of through holes communicated with the interior of the plate body are formed in the plate surface of the plate body, so that sound can conveniently enter the interior of the plate body, and the irregular surface of the special-shaped porous fiber is utilized to increase the reflection path of sound waves, so that the sound waves gradually consume energy, and the sound absorption effect is achieved;
3. the surface of the special-shaped porous fiber is gear-shaped, and the interior of the special-shaped porous fiber is porous honeycomb-shaped, so that the special-shaped porous fiber is strong in verticality and not easy to deform;
4. the special-shaped porous fiber contains a large amount of stagnant air, so that the air heat conduction is poor, and the heat insulation effect can be achieved.
Drawings
The technical scheme of the utility model is further explained by combining the accompanying drawings as follows:
FIG. 1 is a schematic structural view of a lightweight sound-absorbing decorative panel according to the present invention;
FIG. 2 is a cross-sectional view of a shaped porous fiber according to the present invention;
fig. 3 is a schematic structural view of the reinforcing ribs in the plate body according to the present invention.
Wherein: 1. a plate body; 2. a decorative layer; 3. profiled porous fibers; 4. a through hole; 5. and (5) reinforcing ribs.
Detailed Description
The utility model is described in further detail below with reference to the figures and the embodiments.
Fig. 1-3 show a lightweight sound-absorbing decorative sheet of the present invention, which comprises a sheet body 1 and decorative layers 2 respectively disposed on the surface of the sheet body 1; the plate body 1 is of a hollow structure, and special-shaped porous fibers 3 are filled in the plate body; the plate surface of the plate body 1 is respectively provided with a plurality of through holes 4 communicated with the inside of the plate body 1; the decorative plate is small in number of layers, the weight of the decorative plate can be greatly reduced by filling the special-shaped porous fibers 3 in the plate body 1, light weight is achieved, production cost is reduced, sound can conveniently enter the plate body 1 by arranging the through holes 4 communicated with the interior of the plate body 1 on the plate surface of the plate body 1, the irregular surface of the special-shaped porous fibers 3 is utilized, the reflection path of sound waves is increased, energy is gradually consumed, and the sound absorption effect is achieved.
Furthermore, the surface of the special-shaped porous fiber 3 is in a gear shape, such as a five-wheel shape and a six-wheel shape, so that the surface area of the special-shaped porous fiber 3 is increased, and the sound absorption effect is improved;
further, the inside of the special-shaped porous fiber 3 is porous honeycomb-shaped, and is a hollow polyester fiber with four holes, seven holes or nine holes, and the special-shaped porous fiber 3 contains a large amount of stagnant air, so that the air heat conduction is poor, and the heat preservation effect can be achieved.
Furthermore, the titer of the special-shaped porous fiber 3 is 6.67 dtex to 16.67 dtex, and the sound absorption and heat preservation effects are the best.
Further, the inside strengthening rib 5 that is provided with many vertically and horizontally staggered and places of plate body 1, the intensity of ability greatly increased decorative board.
Furthermore, the decorative layer 2 is fixedly connected with the surface of the plate body 1 in an adhesion mode, so that the processing is convenient, and the production cost is reduced.
The above is only a specific application example of the present invention, and the protection scope of the present invention is not limited in any way. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
