Description

  The present invention relates to a flash panel, and more particularly to an improvement of a flash panel in which a decorative plate made of a synthetic resin is bonded to both sides of a frame (frame) via a reinforcing plate.

  Conventionally, as a kind of structural panel, face plates have been formed on both sides of a frame made by assembling wooden squares vertically and horizontally, using an adhesive or the like so as to sandwich the frame. So-called flash panels are known (see, for example, Patent Documents 1 and 2 below). Since this flash panel is light and inexpensive, it is widely used as a wall panel or ceiling panel of a house, a door panel, or a component panel or door panel of furniture or furniture.

  In addition, the flash panels used for these applications are made of a synthetic resin thin decorative plate that gives the design surface of the face plate, and a decorative plate that is bonded to the surface opposite to the design surface side of the decorative plate. Some face plates have a multilayer structure composed of reinforcing plates that reinforce the steel plate. In such a flash panel, generally, a wood board such as a plywood board, a particle board, or an MDF (medium density fiber board) is used as a reinforcing board for reinforcing the decorative board.

  By the way, in recent years, due to the rapid increase in awareness of environmental protection, various products in various fields can be recycled in whole or in part, or even when the whole is discarded. It is required that different members can be easily separated (sorted) so that proper disposal can be easily performed. And being able to satisfy various demands that are conscious of such environmental conservation has increased the value of the product and contributed greatly to sales promotion.

  Under such circumstances, even when the decorative panel is a flash panel made of a synthetic resin, it has been used for the purpose of reducing the environmental load by improving the recyclability and optimizing the disposal as described above. Sometimes, it is desirable that a synthetic resin decorative board can be easily peeled off and separated from a reinforcing board made of, for example, a wooden board. However, in the conventional flash panel, the decorative plate is firmly bonded to the reinforcing plate in order to prevent quality deterioration due to peeling of the decorative plate from the reinforcing plate in use. Therefore, with such a conventional flash panel, it has been extremely difficult to satisfy various requirements in consideration of environmental conservation as described above.

JP 2001-253014 A JP 10-119055 A

  Here, the present invention has been made in the background as described above, and the problem to be solved is that a reinforcing plate and a decorative plate made of synthetic resin are provided on both sides of the frame. In flash panels that are bonded to each other with the reinforcing plate inside, the decorative plate in use can be sufficiently prevented from being peeled off from the reinforcing plate. By being able to be peeled off from the reinforcing plate relatively easily, the environmental performance can be advantageously reduced by improving recyclability and optimizing disposal while maintaining sufficient quality performance during use. The object is to provide a new structure to be obtained.

  The present invention can be suitably implemented in various aspects listed below in order to solve the problems described above or the problems grasped from the description and drawings of the entire specification. Moreover, each aspect described below can be employed in any combination. The aspects or technical features of the present invention are not limited to those described below, and can be recognized based on the description of the entire specification and the inventive concept disclosed in the drawings. Should be understood.

  The gist of the present invention is that a reinforcing plate is bonded to both sides of the frame so as to sandwich the frame, and a synthetic resin makeup is provided on the side of the reinforcing plate opposite to the frame. In the flash panel having a structure in which the plates are bonded, the reinforcing plate is constituted by a laminated paper in which a plurality of papers are laminated and bonded to each other.

  In such a flash panel according to the present invention, it is desirable that the laminated paper constituting the reinforcing plate is formed using recycled paper.

  In the present invention, advantageously, a core material made of a paper honeycomb is disposed between the opposing surfaces of the two reinforcing plates bonded to both surfaces of the frame, and the two reinforcing plates are opposed to each other. The core material is bonded to the surface.

  Furthermore, in this invention, it is preferable that the said frame is formed using a laminated material.

  That is, in the flash panel according to the present invention, as an adhesive for adhering the decorative plate to the reinforcing plate, an adhesive capable of firmly adhering the decorative plate and the reinforcing plate is used similarly to the conventional flash panel. I can do it. For this reason, the adhesive strength of the decorative plate to the reinforcing plate can be made as large as that of the conventional product, so that unnecessary peeling of the decorative plate from the reinforcing plate is advantageously prevented under normal use conditions. obtain.

  And especially in the flash panel which concerns on this invention, since the reinforcement board is comprised with the laminated paper (paperboard), the force which makes it peel from a reinforcement board is applied with respect to a decorative board And delamination occurs between the laminated papers constituting the reinforcing plate. For this reason, the decorative board can be peeled off from the reinforcing board relatively easily by applying a predetermined peeling force to the decorative board.

  Therefore, in the flash panel according to the present invention, deterioration in quality due to peeling of the decorative plate from the reinforcing plate during use can be effectively prevented, while, for example, when the decorative plate becomes unusable due to dirt or damage. By replacing only the decorative plate with a new one, the frame and the reinforcing plate can be effectively used as they are. Moreover, when discarding the whole, the member from which a material differs, such as a reinforcing board which consists of a wooden board, and a synthetic resin decorative board, for example, can be separated and discarded easily.

  Therefore, in the flash panel according to the present invention as described above, it is possible to advantageously realize improvement of recyclability and reduction of environmental load by optimizing disposal while maintaining sufficient quality performance during use. As a result, it is possible to satisfactorily satisfy all the various demands that are conscious of environmental protection, and an improvement in product value that directly leads to sales promotion can be achieved very advantageously.

It is front explanatory drawing which shows one Embodiment of the flash panel according to this invention. It is the elements on larger scale in the II-II cross section of FIG. FIG. 3 is a sectional view taken along the line III-III in FIG. 2. FIG. 4 is an enlarged explanatory view of a part IV in FIG. 2.

  Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings.

  First, FIG. 1 shows a front view of an embodiment of a flash panel according to the present invention, FIG. 2 shows a longitudinal section thereof, and FIG. 3 shows a transverse section thereof. ing. As is clear from these figures, the flash panel according to the present embodiment is formed by attaching one face plate 12 to each side surface of the frame body 10 with the frame body 10 interposed therebetween. It has the same basic structure. A core member 14 is disposed between the opposing surfaces of the two face plates 12 inside the frame body 10, and the core member 14 is bonded to the opposing surfaces of the two face plates 12 and 12. ing.

  More specifically, as shown in FIG. 1 and FIG. 2, the frame 10 has a rectangular frame shape as a whole, and has four longitudinal frame members 16, 16, which have a rectangular cross section. 16 and 16 are assembled so as to exhibit a rectangular shape as a whole and are bonded to each other. As the frame member 16 forming the frame body 10, a material made of a synthetic resin material, a light metal material, or the like can be used in addition to a material made of wood.

  In the present embodiment, the frame material 16 is a square material made of a wood material, and among them, a laminated material of cedar having a small specific gravity. As a result, the weight of the frame 10, and thus the entire flash panel, can be advantageously reduced as compared to the case where the frame member 16 is made of solid square material. The occurrence of warpage of the entire flash panel can be effectively prevented. In addition, effective use of cedar groundboard and small timber, which should be discarded, such as cedar thinning, can be realized advantageously.

The thickness of the frame 10 (dimension indicated by T ₁ in FIG. 2), which is about to be determined appropriately based on the required thickness corresponding to the flash panel applications, generally, 9～50Mm It is said to be about. The adhesive that bonds the frame members 16 to each other is also not particularly limited, and conventionally known adhesives are appropriately selected according to the material of the frame members 16 and used.

  As shown in FIGS. 2 and 3, the core member 14 disposed inside the frame body 10 is made of a known paper honeycomb which is a paper honeycomb structure. Here, the core 14 made of this paper honeycomb is formed using recycled paper such as corrugated cardboard. Such a core material 14 is arranged inside the frame body 10 in a state where hexagonal cells of the paper honeycomb are opened toward both sides of the frame body 10.

  On the other hand, as shown in FIGS. 1 and 2, the two face plates 12 and 12 both have a rectangular flat plate shape, and the decorative plate 18 and the reinforcing plate 20 have the former on the front side and the latter on the back side. It has a multi-layered structure that is laminated and bonded to each other so as to be positioned on each side.

The decorative plate 18 forming the surface of the face plate 12 is made of synthetic resin and is a thin rectangular plate. Specifically, for example, a known thermosetting resin decorative plate such as a melamine resin decorative plate, a polyester resin decorative plate, a polyvinyl chloride resin decorative plate, a polyolefin resin decorative plate, or a thermoplastic resin decorative plate is used. A plate 18 is constructed. A decorative paper on which predetermined printing is performed is embedded inside the decorative board 18, and the printing surface of such a decorative paper is visible on the surface of the decorative board 18. Thereby, the surface of the decorative board 18 is made into the design surface 22 which has a predetermined design. The thickness of the decorative plate 18 (dimension indicated by T ₂ in FIG. 4) will generally be about 0.8 to 1.2 mm, its thickness is not limited in particular, the design The smoothness of the decorative plate 18 of the surface 22 can be ensured, and it is determined appropriately within a range where the weight is not increased unnecessarily.

  On the other hand, the reinforcing plate 20 forming the back surface of the face plate 12 is a rectangular flat plate having the same size as the decorative plate 18, and the thickness thereof is sufficiently thicker than the decorative plate 18. Thereby, the strength of the reinforcing plate 20 is made larger than that of the decorative plate 18. Then, as shown in FIG. 4, the reinforcing plate 20 is bonded to the back surface of the decorative plate 18 opposite to the design surface 22 side by an adhesive layer 24 formed between the decorative plate 18. Thereby, the face plate 12 is formed.

  Thus, the face plate 12 is configured to have a surface formed by the design surface 22 of the decorative plate 18 and a sufficiently large strength (bending rigidity) derived from the strength of the reinforcing plate 20. The adhesive forming the adhesive layer 24 that bonds the decorative plate 18 and the reinforcing plate 20 may be, for example, an emulsion type adhesive such as vinyl acetate type, rubber type, acrylic type, or the like, as in the past. A hot melt adhesive or the like is used.

  And in this embodiment, the reinforcement board 20 adhere | attached on the decorative board 18 has the special structure which is not seen in the conventional flash panel.

  That is, as shown in FIG. 4, the reinforcing plate 20 is different from the plywood, particle board, MDF, etc. used in the conventional product, and a plurality of sheets (here, five sheets) of paper 26 are respectively adhesive layers. The laminated papers are laminated so as to be overlapped with each other via 28 and are bonded to each other by the adhesive layers 28. In addition, the plurality of papers 26 constituting such a reinforcing plate 20 are all made of recycled paper. That is, here, for example, corrugated base paper is used as the reinforcing plate 20 made of laminated paper. In addition to the corrugated cardboard, the laminated paper that forms the reinforcing plate 20 includes two or more paper layers among conventionally known paperboard board and building material base paper, etc. A paperboard or the like formed by bonding them together can be used.

The total thickness of the reinforcing plate 20 (dimension indicated by T ₃ in FIG. 4), although not particularly limited, it is preferably be about 0.6～2.5Mm. This is because when the thickness of the reinforcing plate 20 is less than 0.6 mm, the reinforcing plate 20 is too thin, so that not only the strength is insufficient, but also the surface smoothness is lowered, which is the decorative plate. 18, as a result, the smoothness of the face plate 12 is also adversely affected. In addition, when the thickness of the reinforcing plate 20 exceeds 2.5 mm, the reinforcing plate 20 becomes thicker than necessary, which causes an increase in the weight of the face plate 12.

The number and thickness of the sheets 26 constituting the reinforcing plate 20 and the thickness (the dimension indicated by T _{4 in} FIG. 4) are the strength required for the reinforcing plate 20 and the required thickness of the entire reinforcing plate 20. In general, the number of laminated sheets is usually about 2 to 10 sheets, and the thickness of the paper 26 is the total thickness of the reinforcing plate 20 and the number of laminated sheets of paper 26. It is selected appropriately according to The reason why the preferred range of the number of stacked sheets of paper 26 is 10 or less is that when the sheets 26 are stacked on a large number exceeding 10 sheets, there is a possibility that troubles such as troublesome manufacturing of the reinforcing plate 20 may occur. is there.

Note that the density of the paper 26 constituting the reinforcing plate 20 is desirably set to a value within the range of 0.79 to 0.83 g / cm ³ . This is because when the density is less than 0.79 g / cm ³ , a plurality of papers 20 are stacked and pressure-bonded to produce the reinforcing plate 20, or the produced reinforcing plate 20 and the decorative plate 18. When the face plate 12 is produced by laminating and pressure bonding, a plurality of the laminated papers 20 are partially recessed, and thereby the smoothness of the reinforcing plate 20 and the face plate 12 to be produced. This is because there is a risk of the decrease. Moreover, since the strength of the paper 20 having a density of less than 0.79 g / cm ³ is reduced, the two reinforcing plates 20 made of the laminated paper 20 having such a low strength are stacked on each other. When the papers 20 and 20 are separated from each other, they cannot be separated only between the two papers 20 and 20 stacked on each other. This is because the paper 20 that is further laminated to them is also torn together, and as a result, it is difficult to obtain a beautiful peeled surface. In such a case, for example, when the face plate 12 is once peeled off from the flash panel and replaced with a new face plate 12, there is a concern that the smoothness of the face plate 12 may deteriorate or the adhesiveness may deteriorate. Will occur. On the other hand, when the paper 26 constituting the reinforcing plate 20 exceeds a density of 0.83 g / cm ³ , there is a risk that the reinforcing plate 20 and further the weight of the face plate 12 may be unnecessarily large. The density of the paper 26 is desirably 0.83 g / cm ³ or less.

  And the laminated paper which comprises the reinforcement board 20 needs to have moderate delamination property (peel separation property). Specifically, the reinforcing plate 20 does not cause delamination naturally between the papers 26 that are laminated to each other in a normal use state of the flash panel. When the plate 18 is peeled off from the reinforcing plate 20, it has delamination properties such that the laminated papers 26 are peeled off before the decorative plate 18 is peeled (separated) from the reinforcing plate 20. Must be. That is, the reinforcing plate 20 needs to have a peeling strength between the plurality of papers 26 constituting the reinforcing plate 20 smaller than a peeling strength between the reinforcing plate 20 and the decorative plate 18.

  Accordingly, the delamination strength of the reinforcing plate 20 (value measured using an internal bond tester based on J. TAPPI-No. 54) is preferably about 500 to 650 kPa. As a result, as described above, the decorative plate 18 is laminated on the decorative plate 18 before the decorative plate 18 is peeled off from the reinforcing plate 20 only when the force for peeling the decorative plate 18 from the reinforcing plate 20 is forcibly applied. The paper 26 can be peeled off. In addition, even during the production of the reinforcing plate 20, it can be advantageously avoided that the papers 26 stacked on each other are unnecessarily peeled off.

  In order for the reinforcing plate 20 to have the delamination strength as described above, an adhesive forming an adhesive layer 28 interposed between the papers 26 is used between the reinforcing plate 20 and the decorative plate 18. It is preferable that the adhesive strength is smaller than that of the adhesive forming the adhesive layer 24 interposed therebetween. From this point of view, examples of the adhesive that forms the adhesive layer 28 interposed between the papers 26 include natural adhesives, polyvinyl alcohol adhesives, water-soluble polymer adhesives, and the like. Adhesives generally used in the production of paperboard and the like are preferably used. Further, if the paper 26 constituting the reinforcing plate 20 has a large water absorption rate, a large amount of adhesive penetrates, which causes a decrease in smoothness. Therefore, it is desirable that the paper 26 has a relatively low water absorption rate and water resistance.

  As shown in FIGS. 2 and 4, the two face plates 12 and 12 made of the laminate of the decorative plate 18 and the reinforcing plate 20 as described above have the frame 10 with the reinforcing plate 20 side inward. And the core member 14 are disposed on both sides. Further, under such an arrangement state, between the end faces on both sides in the thickness direction of the frame body 10 and the reinforcing plates 20, or between the opening end faces on both sides in the height direction of the core member 14 and the reinforcing plates 20. The adhesive layer 30 is interposed (FIG. 4 shows only the state in which the adhesive layer 30 is interposed between the frame 10 and the reinforcing member 20). The frame body 10 and the core member 14 and the reinforcing plate 20 of each face plate 12 are bonded together by the adhesive layer 30, thereby forming a flash panel. In addition, as an adhesive for forming the adhesive layer 30 interposed between the reinforcing plate 20 of the face plate 12 and the frame body 10 and the core material 14, it is used for bonding the reinforcing plate 20 and the decorative plate 18. The same type of adhesive as described above is generally used.

  By the way, when producing the flash panel of the present embodiment having such a structure, first, for example, two sheets of corrugated cardboard having the same size as the surface of the target flash panel are prepared as the reinforcing plate 20. To do. On the other hand, two sheets of a decorative board 18 such as a melamine resin decorative board made of a synthetic resin and having the same size as the reinforcing board 20 are prepared by a conventionally known method. And the decorative board 18 is each adhere | attached on the surface on the opposite side to the design surface 22 side with respect to each prepared reinforcement board 20. FIG. Thereby, the two face plates 12 and 12 are produced.

  Separately from this, the core material 14 made of paper honeycomb is prepared by using recycled paper such as corrugated cardboard. Furthermore, the frame body 10 is produced by assembling the four frame members 16, 16, 16, 16 having a predetermined length into a rectangular shape and bonding them together.

  And the target flash panel is produced by performing the same process as the manufacturing process of the conventional flash panel using those prepared members. That is, first, an adhesive layer 30 made of an adhesive as described above is applied to the surfaces on both sides in the thickness direction of the frame 10 and the end surfaces of both side openings of the core 14 made of paper honeycomb. To form. Next, the frame 10 is placed on the outer peripheral portion of the face plate 12 on the side opposite to the decorative board 18 side of the reinforcing plate 20, and the adhesive on one side in the thickness direction where the adhesive layer 30 is formed. The core material 14 made of paper honeycomb is bonded to the center of the arrangement surface of the frame body 10 on the face plate 12 on one opening side end surface on which the adhesive layer 30 is formed. It arrange | positions through the agent layer 30. FIG. After that, another single face plate 12 is arranged on the upper side of the frame body 10 and the core member 14 in the same state as the face plate 12 located on the lower side thereof. Thus, the two face plates 12 and 12 are arranged in a state of facing each other on both sides of the frame body 10 and the core member 14 located inside thereof.

  After that, the frame 10 and the core member 14 are bonded to the two face plates 12 by pressing from both sides so as to sandwich the two face plates 12 and 12. Thus, the intended flash panel is obtained. In the case where the adhesive layer 30 interposed between the frame body 10 and the core material 14 and the two face plates 12 is formed using a hot-melt adhesive, the two face plates 12 are used. , 12 is pressed, each face plate 12 is heated to a predetermined temperature.

  In the flash panel of this embodiment thus manufactured, the decorative plate 18 of each face plate 12 is firmly bonded to the reinforcing plate 20, and the decorative plate 18 is removed from the reinforcing plate 20 in a normal use state. On the other hand, if a force is applied to the decorative plate 18 so that the decorative plate 18 is forcibly separated from the reinforcing plate 20, delamination occurs in the reinforcing plate 20, and the decorative plate 18 It can be separated from the reinforcing plate 20 relatively easily.

  Therefore, in such a flash panel, it is possible to stably ensure good quality that prevents the decorative plate 18 from being detached from the reinforcing plate 20 during use. On the other hand, for example, when the decorative plate 18 cannot be used due to dirt or damage, or when it is desired to change the design of the decorative plate 18, the decorative plate 18 is forcibly removed from the reinforcing plate 20. It can be replaced with a new one or one having a desired design, whereby the frame body 10, the core material 14, and the reinforcing plate 20 can be effectively used without being discarded. In addition, even when the entire flash panel is disposed of, the frame 10 made of a wood material, the paper core 14 and the reinforcing plate 20 to be treated as combustible waste, and the nonflammable waste The decorative plate 18 made of synthetic resin to be processed can be easily separated and discarded.

  Therefore, in the flash panel of this embodiment as described above, it is possible to advantageously realize reduction in environmental load by improving recyclability and optimizing disposal while ensuring sufficient quality performance during use. . In addition, it is possible to flexibly respond to a design change request. As a result, as a product that can greatly contribute to environmental conservation, or as a product that can be easily redesigned, the product value directly linked to sales promotion can be increased extremely advantageously.

  Further, in the flash panel of this embodiment, the frame body 10 is made of laminated material, and the core material 14 and the reinforcing plate 20 of the face plate 12 are formed using recycled paper, so that the waste can be effectively used. ing. This also advantageously increases the value of an eco-friendly so-called eco product.

  Further, in such a flash panel, a core material 14 made of a paper honeycomb is disposed between the two face plates 12 and 12. Therefore, since the reinforcing plate 20 is made of paper, it is advantageous that the strength of the entire flash panel becomes extremely smaller than, for example, a conventional flash panel having a reinforcing plate made of plywood or the like. Can be avoided. Moreover, an increase in the weight of the entire flash panel due to the use of the core member 14 can be suppressed as much as possible.

  The specific configuration of the present invention has been described in detail above. However, this is merely an example, and the present invention is not limited by the above description.

  For example, the plurality of papers 26 constituting the reinforcing plate 20 may be paper made of virgin pulp or used paper. In addition, as the paper 26, at least two kinds of paper made of virgin pulp, waste paper, and recycled paper can be used in combination. Any of these various papers laminated and bonded by a known method can be used as the reinforcing plate 20.

  Furthermore, as the core member 14 disposed between the two face plates 12 and 12, a known member other than the paper honeycomb can be used as long as it can increase the strength of each face plate 12 and eventually the entire flash panel. . The core material 14 is not essential in the present invention.

  In addition, the present invention can be advantageously applied to any of a wall panel, a ceiling panel, a door panel of a house, and a flash panel widely used as a component panel or door panel of furniture or furniture.

  In addition, although not enumerated one by one, the present invention can be carried out in a mode to which various changes, modifications, improvements, etc. are added based on the knowledge of those skilled in the art. It goes without saying that all are included in the scope of the present invention without departing from the spirit of the present invention.
