Description

Functional interior finishing sheet and manufacturing method thereof {A functional interior wallpaper sheet and manufacturing method the same}

The present invention relates to a finishing board for functional building interior and a method of manufacturing the same. More specifically, the present invention relates to a finishing board for functional building interior and a method of manufacturing the same. More specifically, it can be simply manufactured by forming a plurality of through holes in the surface material to be decorated and adhering a board that is lighter and more flexible than wood to the inside of this surface. It is a functional construction that can be lightly and easily attached to the surface of the wall or ceiling of a building like wallpaper to insulate and decorate the room, and can soundproof (sound absorb) indoor noise and cushion the interior when people or animals hit the wall. It relates to interior finishing boards and their manufacturing methods.

In general, eco-friendly, flame-retardant and non-combustible sheets, finishing boards, wallpaper, etc. have been used as surface materials by attaching them to the inner walls of buildings. As the surface material, plywood, MDF (medium-density fiberboard) plywood, or a finished board made by adhering LPM sheets, HPM sheets, PM sheets, etc. to the outer surface of a high-density board is used. It is commonly used by attaching paper wallpaper, insulating sheet wallpaper, or foam block wallpaper on plywood, MDF plywood, or high-density board attached to the wall.

In the general interior wall finishing of these buildings, not only spaces used for residential and commercial purposes, but especially daycare centers, kindergartens, academies for children, nursing homes for the elderly, and gymnasiums, are used to prevent serious injuries when people bump into them. Safety in case of collision with the wall is very important, but conventionally, it is used as is with wallpaper applied to the wall or wood such as plywood, or it is used by attaching a separate foam wall cushion such as sponge or Styrofoam to the inner wall. This would be said to be common.

Accordingly, it is desirable that the interior wall finishing material be given aesthetic elements such as various shapes or shapes so as to display the effect of interior decoration.

In addition, the interior wall finishing material needs to have the safety as described above, and is also required to have sound-absorbing functionality to prevent large amounts of noise generated indoors from leaking to the outside.

In addition, moisture resistance that is not vulnerable to moisture or moisture is required, and flame retardant materials and flame retardant structural functionality that do not burn or easily deform in response to heat or fire are also required.

In general, a plurality of sound-absorbing holes were perforated in the finished board to achieve a sound-absorbing effect.

These conventional finishing boards are made of MDF plywood, plywood, or high-density board, and because they are mainly made of wood, they are heavy, making it inconvenient for workers to transport or install them on the interior walls of buildings, and if they are not strongly attached to the interior walls, There was a risk of being easily separated, making installation difficult, and increasing the use of adhesives, which hindered the indoor environment.

In addition, since conventional finishing boards are made entirely of wood, due to the nature of the material, they are vulnerable to moisture, which reduces durability, and also has limitations in sound absorption and shock buffering performance.

In addition, polyester plywood has been widely used as a finishing board in the past, but it does not have a separate surface layer other than the decorative board, so there are limitations in product design, the range of use is low, so marketability is low, and the material is vulnerable to moisture. As a result, durability was poor, sound absorption and buffering performance were not satisfactory, and it was vulnerable to heat.

In addition, to increase the sound absorption and buffering performance of conventional finishing plates, they were manufactured by laminating layers of sponge or paper (corrugated cardboard) together. In this case, since the sponge and paper (corrugated cardboard) materials are applied as a single layer by bonding them with an adhesive, a multi-layer structure cannot be formed, making the manufacturing process complicated, and because the sponge and paper (corrugated cardboard) are applied in thin layers, it is still difficult to use. There were limitations in sound absorption, buffering, and moisture resistance that could not be satisfied.

Hereinafter, the functional building interior finishing board and manufacturing method of the present invention will be described in detail as an example with reference to the attached drawings. First, we will look at the manufacturing method sequence of decorative plates for building interior materials, and then explain the configuration of the present invention.

As shown in FIGS. 1 and 3, the method of manufacturing the decorative board 100 for building interior materials of the present invention includes a surface material preparation step (S1) of preparing a surface material 10 in the form of a sheet; A plate body preparation step (S2) of preparing a plate body 20 that is light in weight and has elasticity due to the loose texture compared to a wood plate; A surface material perforation step (S3) of perforating the surface material 10 to form a plurality of through holes 11; An adhesive application step (S4) of applying adhesive 12 to the lower surface of the surface material 10; And a joining step (S5) of stacking the surface material 10 and the plate body 20 vertically and joining them.

The surface material preparation step (S1) is a step of preparing the surface material 10, which is prepared by forming a thin sheet of any one of metal, non-ferrous metal, paper, wood, film, fiber, synthetic resin, and rubber material. .

The surface material 10 creates various decorative effects depending on the material. For example, in the case of a metal material, it creates a luxurious yet cold atmosphere, in the case of a textile material, a warm and friendly atmosphere, and in the case of a wooden material, a nature-friendly atmosphere. Depending on the material, various decorative effects can be created. In addition, the surface material 10 can produce various designs by processing the outer surface. For example, the outer surface is processed in any one of polishing, embossing, printing, painting, coating, painting, and transfer to form a pattern. You can create various designs.

In the manufacturing method described above in sequence, the plate body preparation step (S2) is a step of preparing the plate body 20, and although not separately shown in the drawings, as an embodiment of the present invention, the plate body 20 ) can be manufactured by basically mixing thin and thick threads made of fiber or synthetic resin with a binder in a cut state and compression molding them into a plate form. In this case, there is no need to form a separate noise-absorbing hole (H) in the plate body, and if the forming process is not difficult, the noise-absorbing hole can be formed.

The above fibers or synthetic resins are generally made of materials with excellent sound absorption, buffering, and moisture resistance properties. Since they are mixed in the form of thin and thick threads cut to an appropriate length for mixing and molding, large and small internal pores are formed between them to absorb sound, The functions of buffering and invasion will be greatly improved. The structure of the board made in this way has a more loosely intertwined structure than that of wood, forming internal pores, which not only has the effect of being light and elastic, but also maintains the shape of the board well, allowing it to be used as an interior material.

In addition, the plate body 20 can be manufactured by preparing one or more of sponge, Styrofoam, fiber, rubber, synthetic resin, and wood in the form of small pieces, mixing them with a binder, and compression molding them into a plate shape.

In other words, one or more of the above materials such as sponge, Styrofoam, fiber, rubber, synthetic resin, and wood are not applied as a layered structure of the plate as in the past, but are mixed with a binder in the form of small pieces, so that the texture of the plate is similar to that of the wood. In addition to being looser and more flexible, it maintains the shape of the board well and has superior sound absorption, buffering, and moisture resistance performance compared to conventional wood.

In the above-described manufacturing method, the surface material perforation step (S3) is a step of forming a plurality of through holes 11 in the surface material 10 by perforating the surface material 10. Here, the through hole 11 can be formed in a circular shape, polygonal shape, or other various patterns to create a design effect due to the shape of the through hole 11. The through hole 11 may be formed by NC, pressing, punching, etc.

In addition, the adhesive application step (S4) is a step of applying the adhesive 12 to the lower surface of the surface material 10.

In addition, the bonding step (S5) is a step of bonding the surface material 10 and the plate body 20, in which the adhesive 12 at the bottom of the surface material 10 and the plate body 20 are stacked facing each other up and down. This is the step of manufacturing the decorative plate 100 by joining. Here, the surface material 10 and the plate body 20 are preferably bonded by press pressing or heat press pressing.

The decorative plate 100 manufactured by the manufacturing method of the present invention as described above has a plurality of through holes 11 formed in the surface material 10 as shown in Figures 2 and 4, and the lower part of the surface material 10 It is constructed by joining a board body 20 that is lighter and more elastic than a wooden board and absorbs noise flowing in through the through hole 11 using an adhesive 12.

Ultimately, the present invention forms a plurality of through holes 11 of one shape or a mixture of several shapes in the surface material 10, and applies adhesive 12 to the lower part of the surface material 10, making it lighter than a wooden board and It is manufactured by joining an elastic plate body 20, and the surface material 10 is made of a sheet material such as metal, non-ferrous metal, paper, wood, film, fiber, synthetic resin, or rubber material, and the outer surface is polished, embossed, printed, etc. It is designed by painting, coating, painting, and transfer methods, and the plate body 20 is made by mixing thin and thick threads made of fiber or synthetic resin with a binder in a cut state, or using sponge, Styrofoam, fiber, rubber, synthetic resin, wood, etc. It is manufactured by mixing it with a binder in the form of small pieces and compression molding, so the overall manufacturing process is simple and various designs can be expressed, which has excellent decorative properties. It is light in weight, making construction convenient, and provides excellent sound absorption, buffering, and moisture resistance performance. .

Meanwhile, in the present invention, as shown in other drawings in addition to the structure of FIG. 4 described above, in order to expand the sound absorption effect by the plate body 20, the plate body 20 is positioned in communication with the through hole 11 in the plate body 20. It can be configured to increase the soundproofing effect by forming a noise-absorbing hole (H) in the sound-absorbing hole (H) so that the sound-absorbing wavelength is reflected and absorbed internally.

That is, noise sound-absorbing holes (H) connected to the through hole 11 of the decorative surface material 10 are formed in the plate body 20 and flow into the plate body 20 through the through hole 11. It is constructed to expand the sound-absorbing area.

The noise-absorbing holes (H) do not completely penetrate the plate body 20, but have a side cross-sectional shape of 'U', 'V', ' ', '〈〉 (H shape in a in Figure 9)', '( )' shaped grooves are used, or a combination of more than one is used.

As shown in Figure 6b and Figure 7a, the noise-absorbing holes (H) completely penetrate the top and bottom of the plate body 20, and have a constant upper and lower cross-sectional width on the side cross-section. |' Shape, upper-lower-gwang in lateral cross-section. 'through hole (H shape in a in FIG. 7, H shape in b in FIG. 9) (H shape in b in FIG. 7), '<>','()', any one selected from the shaped through holes, or It can be done using more than that.

In addition, the present invention can be used by attaching two layers 20 and 40 of the same or similar material to the plate body 20, and the noise absorption is achieved by attaching the two layers 20 and 40. The ball (H) is used by attaching it so that it is aligned to the position where the shape is completed, and this is shown in the drawing a of Figure 9. This structure is advantageous for forming a noise inlet hole with a large intermediate width.

Of course, it can also be used by attaching it to the lower part of the plate body 20 as an auxiliary body layer 40', as shown in figure b of FIG. 9. The auxiliary body layer 40' is preferably made of a material that can be easily attached to the wall, and does not necessarily need to be made of a material similar to a plate. That is, for example, the auxiliary body layer 40' may be used in cases where it is difficult to attach and fix the plate body 20 to the wall. It will also be useful if you use it. In addition, the embodiment in which the auxiliary body layer 40 is additionally configured will be more useful in terms of sound absorption function when the noise sound-absorbing hole (H) is formed completely through.

As in the embodiment described above with reference to FIG. 4, the auxiliary body layer 40 may be formed by mixing thin threads and thick threads made of fiber or synthetic resin with a binder and compression molding, and may be used as is or as a base material. It will be.

Meanwhile, the present invention may be configured as shown in FIG. 10 by using the internal pores of the plate body without drilling the noise-absorbing hole (H). That is, a lower surface material 50 having a separate plurality of through holes 51 that is the same or similar to the decorative surface material 10 having the plurality of through holes 11 is further attached to the lower part of the plate body 20. It can be formed, and when configured in this way, it will be easy to use the same material as the lower surface material 50 without preparing a separate material from the upper decorative surface material 10, thereby making it easy to adhesively attach to the wall. No adhesive material is required for adhesive attachment due to the through hole, and in the case where noise transmitted from the wall comes in, the noise is transmitted through the through hole 51 into the internal pores of the plate body without passing through the blocked lower layer structure. It can be soundproofed by immediately absorbing sound.

Meanwhile, the plate body 20 having the noise-absorbing hole (H) may generally be formed as follows. In other words, it is sufficient to use a small piece of one or more of sponge, styrofoam, fiber, rubber, synthetic resin, and wood mixed with a binder and compression molded.

Likewise, the surface material 10 is made of any one of metal, non-ferrous metal, paper, wood, film, fiber, synthetic resin, and rubber in the form of a sheet, and the outer surface of the surface material 10 is polished. The processed pattern is formed by any one of embossing, printing, painting, coating, painting, and transfer, and the through hole 11 is prepared by drilling into one or more of the shapes of a circle, polygon, or star and laminated. So use it.

Figure 8 shows the process of processing the shape of the noise-absorbing hole when the noise-absorbing hole has an upper-lower-light structure as shown in Figure 7, that is, laminating the surface material on which the through hole 11 is formed and the plate body as shown in Figure 7. After attachment, the noise-absorbing hole is processed based on the position of the through hole (11). However, the present invention is not limited to this, and before laminating and attaching the surface material and the plate body, the plate body base is turned over to make hole processing of the upper and lower lights easier, and the noise-absorbing holes of the upper and lower lights are punched out as shown in Figure 7 a, b. It can also be formed by turning it over again, aligning it with the through hole, and attaching it to the surface material.

That is, if the shape of the sound-absorbing hole (H) of the plate body 20 has a width of the lower section attached to the wall in the side section larger than the width of the upper section, the lower section is used to form the noise-absorbing hole (H). It means perforating and processing from.

Meanwhile, the present invention is not limited to this, as shown in the drawing a of FIG. 9, when the shape of the noise sound-absorbing hole (H) of the plate body 20 has a width of the middle cross-section larger than the width of the upper and lower cross-sections, the shape is half each. It is also possible to form the noise-absorbing hole (H) by stacking two sheet body plates (20) forming the sound-absorbing hole (H).

The drawings of the multiple embodiments described above show various embodiments for expanding the internal area of the noise-absorbing hole (H) and shaping the shape of the inner surface of the sound-absorbing hole (H). In other words, the larger the internal area, the wider the surface that absorbs sound flowing into the structure of the plate body, and the shape of the inner surface of the sound-absorbing hole determines the reflection angle of some of the reflected sound as the incoming noise is absorbed inside the sound-absorbing hole. These may correspond to useful configurations for soundproofing the present invention.

As described above, the present invention can be implemented in various structures, but the ultimate purpose of the present invention, which is the through hole 11 of the surface material 10, while sufficiently demonstrating the function of indoor soundproofing (sound absorption) and cushioning against collision. In case of moisture seeping inside and accumulating moisture, the material structure of the plate body retains the moisture and then evaporates and releases the moisture to the outside of the surface material 10 through the through hole 11, so it acts as a moisture barrier. can also be implemented effectively.
