Description

  The present invention relates to a panel. More specifically, it is a panel in which a paper layer is pasted on the surface of a core material having a core structure, and a decorative board is further pasted on the surface of the paper layer, and the paper is mainly derived without using wood itself at all. It is environmentally friendly by using only raw materials, and it has a beautiful appearance without the core shadow appearing on the surface of the decorative board, has a light and sufficient surface hardness, and can be used for kitchen cupboards, etc. .

  In the past, woody materials such as wood chips were often used for kitchen doorboards, for example. Recently, these materials have been attracting attention as bioenergy sources, and the price has risen. Is becoming difficult to obtain. In consideration of the environment, paper and biodegradable raw materials tend to be used for various articles such as doorboards rather than wooden raw materials, but these are stronger than wooden raw materials. It has been pointed out that it is inferior, and there was a problem that the strength of the doorboard itself was inferior when using paper raw materials. Moreover, when attaching a doorplate to a cupboard via a hinge, there existed a problem that the effect of a screw was bad.

  Therefore, in order to increase the strength of the door plate itself, it has been proposed to increase the surface hardness of the door plate by adopting a core material having a core structure such as a honeycomb core as the door plate core material. Even when the hardness is increased, in order to install the hinge, it is necessary to place a wooden core around the core structure and to make a screw-fastening hole in the wooden core. In the end, we had to use wooden materials.

  In addition, in order to improve the appearance of the appearance, a decorative board may be attached to the surface of the core material having the core structure. In this case, the core shadow of the core material of the core structure is lifted on the surface of the decorative board. On the other hand, it was pointed out that it was detrimental to aesthetics.

  The present invention has been made in view of the above-mentioned conventional problems, and uses only raw materials mainly derived from paper without arranging a core made of wood itself around a core having a core structure.

  Hereinafter, although the panel of this invention is demonstrated in detail, referring an Example, this invention is not limited to these at all.

Example 1
As shown in FIG. 1A, the panel 1 of Example 1 includes a core material 2 having a core structure, a paper layer 3 attached to the surface of the core material 2, and a surface of the paper layer 3. It consists of the decorative board 4 stuck.

  The core material 2 has a core structure such as a paper honeycomb panel, a honeycomb core, or a roll core. The shape of the core material 2 includes various shapes such as a hexagon, a triangle, a quadrangle, and a polygon. A cross-sectional shape can be employed. As the material, virgin pulp paper, recycled paper, and the like can be used, but recycled paper is preferably used in consideration of environmental considerations.

  Moreover, the compressive strength in the thickness direction can be increased by adopting the core structure. As shown in FIG. 1A and FIG. 7, the core structure includes a large number of flat cylindrical cells 2 a having a hexagonal cross section so as to be in close contact with each other. Both ends are sandwiched. As a result, when a force is applied in the thickness direction, the load is distributed to each cell, so that the panel 1 is improved in compressive strength and reduced in weight despite being made of fragile recycled paper. Can also be realized. Further, in particular, when a paper honeycomb panel is adopted, a very high strength can be imparted in the thickness direction, and since the core structure is a closed space, air convection hardly occurs in the panel 1. Temperature and humidity are hardly transmitted before and after. Therefore, temperature and humidity can be separated in both spaces separated by the panel 1. For example, when the panel 1 is used as a doorplate of a kitchen cupboard, even if the kitchen becomes hot and humid, the inside of the kitchen cupboard does not become hot and humid, and sufficient consideration is given to the hygienic aspects inside the cupboard. Is possible.

  In addition, although the thickness of the core material 2 which has a core structure can be designed suitably according to a use purpose, a thing of 8-40 mm is preferable in relation to compression strength. When the thickness of the core material 2 is smaller than 8 mm, the compressive strength tends to be inferior. When the thickness is larger than 40 mm (for example, 100 mm), a paper honeycomb panel having a compressive strength is required. There is no need to use the core material 2 having a thickness larger than 40 mm.

  As the paper layer 3, cardboard, paper tube base paper, gypsum board base paper or the like can be used. The paper layer 3 serves as a base material for attaching a decorative plate 4 to be described later, and can prevent the core shadow of the core material 2 from floating on the surface of the decorative plate 4 after being applied.

  The method for attaching the paper layer 3 and the core material 2 is not particularly limited, but it is preferable to use a biodegradable resin adhesive in consideration of environmental considerations. Biodegradability refers to the property of being naturally decayed by bacteria in the ground or water and finally being decomposed into water, carbon dioxide, ammonia, and the like.

  The paper layer 3 is important for preventing wobble of the screw 5 when the hinge 6 is hinged to the panel 1 with the screw 5. That is, if the paper layer 3 is too thin, the screws 5 are wobbled, so that the fixing is insufficient and the hinge 6 cannot be firmly attached. The thickness of the paper layer 3 is preferably about 0.5 to 1.5 mm. If the thickness is less than 0.5 mm, the screws 5 are wobbled and the fixation is unstable, and the core shadow of the core material 2 is reflected. Tend. Further, if the thickness is 1.5 mm, the screw 5 can be prevented from wobbling, and the thickness of the core material 2 is sufficient to prevent the shadow of the core material 2 from appearing. There is no.

  Even when the paper layer 3 having a small thickness is used, as shown in FIG. 2B, a plurality of sheets (in the case of two paper layers 3 in FIG. 2B) are overlapped. By combining them, it is possible to prevent the screw 5 from wobbling and the core shadow of the core material 2 from appearing.

  Examples of the decorative board 4 include a melamine board, a poly board, a film decorative board, and an MDF (medium density fiber board), but the wood-like appearance is beautiful, and it is thin with paper and has high rigidity. A melamine plate is particularly preferable in this respect. Although the thickness of the decorative board 4 is not specifically limited, Generally about 0.8-5 mm is preferable.

  The method of attaching the decorative board 4 and the paper layer 3 is not particularly limited, but it is preferable to use a biodegradable resin adhesive in consideration of the environment as described above.

  As shown in FIG. 1B, the edge tape 7 is attached to the end face in the thickness direction of the panel 1 of the first embodiment, thereby further improving the aesthetic appearance, the outside air inside the core structure, and the humidity. Inflow can be prevented.

  As the edge tape 7, a tape made of polyolefin such as polypropylene and vinyl chloride can be used. In addition, the method for attaching the edge tape 7 is not particularly limited, but generally, an edge machine having an adhesive function to the edge tape 7 and an adhesive function of the glued edge tape 7 is used. can do. The glued edge tape 7 is affixed to the end face of the decorative board 4, the end face of the paper layer 3, and the end face with the core material 2 (cut surface of the core structure).

Example 2
As shown in FIGS. 3 (a) and 3 (b), the panel 8 of Example 2 is applied to both surfaces of the first paper layer 9a and the first paper layer 9a that are stacked one or more times. It consists of a core material 10 having a core structure formed, a second paper layer 9b attached to the surface of the core material 10, and a decorative board 11 attached to the surface of the second paper layer 9b.

  As in the panel 8 of the second embodiment, the paper layer is increased and the screw 13 for attaching the hinge 12 is longer than a certain length (when the hinge 12 is fixed, the tip of the screw 13 is the first paper layer 9a. The length of the screw 13 is longer than that necessary for penetrating through the first paper layer 9a and the second paper layer 9b. As a result, the screw 13 is fixed at three places by the fixing portion with the first paper layer 9a, the fixing portion with the second paper layer 9b, and the fixing portion with the decorative board 11, so that the first embodiment As a result, the hinge 12 can be fixed more firmly than the screw fixing in the panel 1, and as a result, the hinge 12 can be prevented from wobbling. Therefore, even when a relatively thin paper layer such as the paper layer 3 in Example 1 as shown in FIG. 2A is used, the hinge 12 can be sufficiently fixed. is there.

  In order to fix the hinge 12 more reliably, as shown in FIG. 3B, a plurality of first paper layers 9a (in the case of two first paper layers 9a in FIG. 3B) are used. The number of the first paper layers 9a can be selected as appropriate.

  The raw materials and roles of the first paper layer 9a and the second paper layer 9b are the same as those of the paper layer 3 of Example 1, and the core material 10 and the decorative board 11 are the core material 2 of Example 1. Since these are the same as those of the decorative plate 4 and the pasting methods are the same, the description thereof is omitted. Further, similarly to the panel 1 of the first embodiment, an edge tape can be applied to the end face in the thickness direction of the panel 8.

Example 3
As shown in FIG. 4, the panel 14 of the third embodiment includes a first core member 15a having a core structure and one or a plurality of first core members 15a attached to both surfaces of the first core member 15a. One paper layer 16a, a second core material 15b having a core structure affixed to the surface of the first paper layer 16a, and a second paper layer affixed to the surface of the second core material 15b 16b and the decorative board 17 affixed on the surface of the second paper layer 16b.

  Like the panel 14 of Example 3, the panel 14 with various thicknesses can be obtained by increasing the thickness of the first core member 15a. Moreover, the panel 14 of Example 3 can also be made into 1 or more 1st paper layers 16a similarly to the panel 8 of Example 2. FIG. Thereby, it is possible to freely design the thickness of the panel 14 while realizing strong screwing.

  The raw materials and roles of the first paper layer 16a and the second paper layer 16b are the same as those of the paper layer 3 of Example 1, and the raw materials of the first core material 15a and the second core material 15b, The role is the same as that of the core material 2 of the first embodiment, and the decorative plate 17 is the same as the decorative plate 4 of the first embodiment. Moreover, it is also possible to apply an edge tape to the end surface in the thickness direction of the panel 14 as in the panel 1 of the first embodiment.

Example 4
As shown in FIG. 5, the panel 18 of Example 4 includes a first core material 19a having a core structure, a first paper layer 20a attached to the surface of the first core material 19a, The intermediate layer 21 applied to the surface of the first paper layer 20a, the second paper layer 20b applied to the surface of the intermediate layer 21, and the second applied to the surface of the second paper layer 20b. Core material 19b, a third paper layer 20c affixed to the surface of the second core material 19b, and a decorative board 22 affixed to the surface of the third paper layer 20c.

  By providing the intermediate layer 21 as in the panel 18 of the fourth embodiment, the strength of the panel 18 itself can be increased, and a stronger screw can be secured.

  At that time, it is preferable that the screw 23 has a length longer than a certain length (when the hinge 24 is fixed, the tip of the screw 23 has a length reaching the intermediate layer 21 through the second paper layer 20b. It is particularly preferable that the tip has a length longer than that required for inserting the intermediate layer 21 and also the first paper layer 20a, so that the screw 23 is intermediate between the first paper layer 20a and the first paper layer 20a. The layer 21, the second paper layer 20b, and the third paper layer 20c can be inserted. Thereby, the screw 23 is fixed to the first paper layer 20a, fixed to the intermediate layer 21, fixed to the second paper layer 20b, and fixed to the third paper layer 20c. The hinge 24 can be fixed more firmly than the screws in the panel 1 of the first embodiment and the panel 8 of the second embodiment because of being fixed at five places by the fixing portion with the decorative plate 22, and as a result The wobbling of the hinge 24 can be prevented.

  The intermediate layer 21 is preferably selected to have a thickness of about 1.0 to 3.0 mm. For example, China plywood that is softwood plywood, Lauan plywood that is hardwood plywood, poplar plywood, MDF, particle board, A melamine backer or the like can be used.

  The method of attaching the intermediate layer 21 and the first paper layer 20a and the intermediate layer 21 and the second paper layer 20b is not particularly limited, but as described above, biodegradable resin bonding is performed in consideration of the environment. It is preferable to use an agent.

  The raw materials and roles of the first paper layer 20a, the second paper layer 20b, and the third paper layer 20c are the same as those of the paper layer 3 of Example 1, and the first core material 19a and the second paper layer 20c are the same. The core material 19b has the same raw material and role as the core material 2 of the first embodiment, and the decorative plate 22 is the same as the decorative plate 4 of the first embodiment. Therefore, explanation is omitted. Similarly to the panel 1 of the first embodiment, an edge tape can be applied to the end face in the thickness direction of the panel 18.

Example 5
As shown in FIG. 6, the panel 25 of Example 5 includes an intermediate layer 26, a first paper layer 27a attached to both surfaces of the intermediate layer 26, and a surface of the first paper layer 27a. It consists of a core material 28 having an affixed core structure, a second paper layer 27b affixed to the surface of the core material 28, and a decorative board 29 affixed to the surface of the second paper layer 27b.

  The raw materials and roles of the first paper layer 27a and the second paper layer 27b are the same as those of the paper layer 3 of the first embodiment, and the raw materials and roles of the core material 28 are the core material 2 of the first embodiment. The decorative plate 29 is the same as the decorative plate 4 of the first embodiment, and the raw material and role of the intermediate layer 26 are the same as those of the intermediate layer 21 of the fourth embodiment. Since the method is the same, the description is omitted. Further, similarly to the panel 1 of the first embodiment, an edge tape can be applied to the end face in the thickness direction of the panel 25.

  In Examples 1 to 5, the case where a screw is used as the hinge fixing means is illustrated, but the fixing means of the present invention is not limited to this, and various fixing means can be adopted.

  Moreover, although the common flat hinge was illustrated as a hinge, as a hinge which can be used for this invention, it is not limited to this, A various hinge can be used. For example, when using a slide hinge, open the cup for attaching one (cup part) of the slide hinge to the panel side and fix the slide hinge, and then attach the other slide hinge to the frame of the installation cabinet. What is necessary is just to adhere to.

  As described above, according to the panel of the present invention, without using a core material made of wood itself around a core material having a core structure, only a raw material mainly derived from paper is used for installing a hinge or the like. Thus, it is possible to provide a panel that can increase the strength of the screws, is environmentally friendly, has excellent installation convenience, and has a good appearance without causing a core shadow on the surface of the decorative board.
