(a) is a rear view showing a schematic configuration of a decorative sound absorbing panel according to a fourth embodiment of the present invention, and (b) is a cross-sectional view taken along line III-III, corresponding to FIG. .

Next, embodiments of the invention will be described with reference to the drawings.

Referring to FIG. 1, a decorative sound absorbing panel 10 according to a first embodiment of the present invention is plate-shaped, and includes a sound absorbing material 20, an adhesive layer 21 formed on the sound absorbing material 20, and an adhesive layer 21 formed on the adhesive layer 21. and a decorative material 24 formed in the The decorative material 24 has a fabric 22 and a pattern 23 formed by sublimation ink soaked into the fabric 22.例文帳に追加The planar shape can be any shape, and examples thereof include a rectangular shape, a circular shape, and an elliptical shape. The decorative sound-absorbing panel 10 is applied, for example, to interior wall surfaces and partitions where silence is required, or to paintings having sound-absorbing performance.

As the sound absorbing material 10, for example, a porous board sound absorbing material or a perforated board sound absorbing material can be used. As the porous plate sound absorbing material, for example, a resin fiber sound absorbing material, glass wool, or rock wool can be used. As the resin fiber sound absorbing material, it is preferable to use a polyester sound absorbing material. As the perforated plate sound absorbing material, a plate-like material such as a gypsum board, a slate board, and a metal plate having a large number of holes formed therein can be used. The thicker the sound absorbing material 20, the greater the sound absorbing effect in the low sound range. Therefore, the thickness of the sound absorbing material 20 is preferably 10 mm to 40 mm. If the thickness is 10 mm or more, a sound absorbing effect can be expected over a wide sound range.

The adhesive layer 21 is a fixing member for fixing the sound absorbing material 20 and the decorative material 24 . Any material may be used as long as the sound absorbing material 10 and the fabric 22 used for the decorative material 24 can be adhered, and for example, a hot melt adhesive can be used.

The decorative material 24 expresses an arbitrary design by means of a pattern 23 formed by sublimation ink on the cloth 22 . The fabric 22 is a material that is made of fibers and has voids between the fibers that extend from the front surface to the back surface. For example, polyester fabric can be used. By using sublimation ink as the pattern 23, the fibers forming the fabric 22 are soaked with the sublimation ink, leaving voids in the fabric 22. - 特許庁Therefore, the sound passes through the gap that passes from the front surface to the back surface of the fabric 22 and reaches the sound absorbing material 20 . On the other hand, when the pattern 23 is formed as a film on the fabric 22 by a method such as UV inkjet printing, the sound is less likely to reach the sound absorbing material 20, and the sound absorbing effect is likely to be impaired. The thickness of the decorative material 24 is preferably 0.10 mm to 1.0 cm, more preferably 0.10 mm to 1.0 mm. If the thickness is 0.10 mm or more, the fabric 22 has a thickness that does not easily tear during manufacturing or use of the decorative sound absorbing panel. On the other hand, if the thickness is 1.0 cm or less, the overall thickness of the decorative sound absorbing panel 10 does not become too thick, making it easy to attach to the wall surface. Also, if the thickness is 1.0 mm or less, the sublimation ink will easily permeate.

Next, the decorative sound absorbing panel 10 using the perforated plate sound absorbing material 26 as the sound absorbing material 20 will be described.

a perforated plate sound absorbing material 26 in which a plurality of holes are formed in a plate-like material; an adhesive layer 21 formed on the perforated plate sound absorbing material 26 while avoiding the plurality of holes of the perforated plate sound absorbing material 26; and a decorative material 24 formed on the adhesive layer 21 . In the perforated plate sound absorbing material 26, when sound passes through the holes, friction occurs around the holes and the sound is converted into thermal energy, thereby absorbing the sound. Therefore, by forming the adhesive layer 21 avoiding the holes of the perforated plate sound absorbing material 26 so that sound can pass through the holes, the decorative sound absorbing panel 10 that does not interfere with the sound absorbing effect of the perforated plate sound absorbing material 26 is obtained.

The perforated plate sound absorbing material 26 is a plate-shaped material such as a gypsum board, a slate board, or a metal plate, and has a plurality of holes with a diameter of 5 mm to 15 mm and an aperture ratio of 10% to 40%. A plurality of holes may be formed, and two or more types of holes having different diameters may be formed. Since the sound range that can absorb sound differs depending on the diameter of the holes of the perforated plate sound absorbing material 26, when two or more kinds of holes having different diameters are formed, a sound absorbing effect can be expected in a wider sound range.
For other materials, the same materials as those described above can be used.

Next, a method for manufacturing the decorative sound absorbing panel 10 will be described.

Referring to FIG. 2A, sublimation ink is printed on a base sheet 30 made of paper by an inkjet printer to prepare a transfer sheet 50 having a pattern 23 on the base sheet 30 .

The base paper 35 is overlaid. Next, the transfer sheet 50, the fabric 22 and the base paper 35 are inserted into a rotary drum type transfer machine (not shown), and the transfer sheet 50, the fabric 22 and the base paper 35 are passed between the cylindrical drum 87 and the cylindrical roll 88. The pattern 23 is transferred onto the fabric 22 by heating to about 150° C. to 200° C. and applying pressure to about 0.1 kg/cm ² to 2 kg/cm ² by the drum 87 while sending it in the traveling direction 90 so as to pass through it. . Next, the decorative material 24 is peeled off from the base paper 35 to prepare the decorative material 24 . Here, the pattern 23 formed on the fabric 22 is formed by soaking the fabric 22 with sublimation ink.

Next, referring to FIG. 2(c), an adhesive layer 21 is formed over the entire surface of the sound absorbing material 20. Next, as shown in FIG. Next, the decorative sound absorbing panel 10 shown in FIG. 1 is manufactured by laminating the back surface of the decorative material 24, that is, the surface opposite to the surface on which the pattern 23 is transferred, onto the adhesive layer 21 on the sound absorbing material 20. be done.

As described above, in the decorative sound absorbing panel 10 manufactured as described above, the pattern 23 is formed on the fabric 22 by sublimation transfer. It has a gap through which sound can pass through the decorative material 24 and reach the sound absorbing material 20. - 特許庁Therefore, even if the pattern 23 is attached to the sound absorbing material 20, the decorative sound absorbing panel 10 can be obtained without hindering the sound absorbing effect of the sound absorbing material 20. - 特許庁Furthermore, since the sound absorbing material 20 and the decorative material 24 are firmly fixed by the adhesive layer 21, the sound absorbing material 20 and the decorative material 24 are difficult to separate, and the decorative sound absorbing panel 10 with high durability is obtained.

Referring to FIG. 2( a ), the transfer sheet 50 is for sublimation transfer of the pattern 23 to the fabric 22 , and the pattern 23 is formed on the base sheet 30 . As a method for forming the pattern 23, for example, printing by an inkjet printer, gravure printing using a plate, or offset printing can be used. Since the pattern 23 formed here becomes a mirror image when transferred to the fabric 22 , the pattern 23 is formed in a positional relationship corresponding to the mirror image of the pattern 23 formed on the fabric 22 . As the base sheet 30, any material can be used as long as the pattern 23 can be formed on the base sheet 30 and the material can be sublimated and transferred to the fabric 22. For example, paper or a resin sheet can be used. As the resin sheet, polyester, polyamide, polyimide, polyaramid, polycarbonate film or the like can be used.

When the pattern 23 formed by the sublimation ink from the transfer sheet 50 is sublimated and transferred to the fabric 22, the base paper 35 is sublimated by the sublimation ink passing through the fabric 22 soaking into the base paper 35 and sublimating in the transfer machine and the room. This is to prevent ink from sticking. Further, when the cloth 22 and the transfer sheet 50 are thin and difficult to handle, a rigid base paper 35 may be used to improve handling.
