A regular pattern is applied to the film exterior material 3A. Even in the case that a wrinkle 13 is formed on a surface of the film exterior material 3A due to a void or the like formed on the resin foam insulation 2, the wrinkle 13 can be inconspicuous among the pattern. A good appearance of the produced heat insulation panel thus can be kept.

Description

  The present invention relates to a heat insulating panel made of foamed resin used as a building material for a building such as a house.

  Conventionally, heat-insulated panels made of foamed resin used as building materials are configured in a plate shape by bonding and fixing film-like exterior materials such as aluminum foil to the surface of foamed resin heat-insulating materials such as rigid urethane foam. (For example, refer to Patent Documents 1 and 2).

  In Patent Document 1, a void (cavity) is formed at the interface between the foamed resin heat insulating material and the film-shaped exterior material due to the mixing of bubbles, and an object is to improve quality defects associated with the void.

  In Patent Document 2, due to uneven application of the adhesive, a gas such as air is locally mixed between the foamed resin heat insulating material and the film-shaped exterior material, and thereby locally expanded. The problem is to improve the problems such as the fact that the parts are scattered and the appearance is not good.

  As described above, in the production of a heat insulating panel, there has been a problem due to mixing of bubbles and gas, and efforts have been made for these problems.

  However, considering foaming the raw material in an environment exposed to air (Patent Document 1) or applying an adhesive in an environment exposed to air (Patent Document 2), mixing of bubbles and the like is completely eliminated. It is considered extremely difficult to prevent. If it is possible to completely eliminate the mixing of bubbles and the like, it is expected that a huge cost is required.

  On the other hand, even if bubbles or the like are mixed, if a product with a level that can sufficiently exhibit functions such as heat insulation performance is manufactured, the remaining problem may be an aesthetic problem of the product. .

  Therefore, in view of the above problems, the present invention is a manufactured heat insulating panel even if a void or the like is generated between the foamed resin heat insulating material and the film-shaped outer covering material due to mixing of bubbles or the like. We propose a new technology to ensure the beauty of

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

That is, as described in claim 1,
A foamed resin heat insulating material molded into a plate shape;
A film-like exterior material bonded to at least one side of the plate surface;
A thermal insulation panel having
A regular pattern is given to the film-shaped exterior material.

Moreover, as described in claim 2,
The regular pattern is formed by applying an integral uneven shape to the film-shaped exterior material and the foamed resin heat insulating material.

Moreover, as described in claim 3,
The regular pattern is formed by regularly arranging geometric figures,
The geometric figure has a maximum width of 1 cm to 10 cm, more preferably a maximum width of 2 cm to 8 cm, and still more preferably a maximum width of 4 cm to 8 cm.
It is something to do.

  As effects of the present invention, the following effects can be obtained.

That is, in the invention according to claim 1,
Even when wrinkles are formed on the surface of the film-like exterior material due to voids formed in the foamed resin heat insulating material, it is possible to make the wrinkles less noticeable by the pattern, and the manufactured heat insulation The aesthetics of the panel can be secured.

In the invention according to claim 2,
An appearance with a three-dimensional effect is obtained, and this three-dimensional effect affects the visual sense, and an effect of making the wrinkles less noticeable can be obtained.

In the invention according to claim 3,
It is possible to obtain a three-dimensional effect on the surface of the heat insulating panel and to make the wrinkles less noticeable.

The perspective view shown about the outline | summary of the heat insulation panel concerning one Embodiment of this invention. Sectional drawing shown about the outline | summary of the heat insulation panel concerning one Embodiment of this invention. (A) is a perspective view shown about the outline | summary of the surface of the heat insulation panel concerning one Embodiment of this invention. (B) is a perspective view shown about the outline | summary of the surface of the heat insulation panel in case an uneven | corrugated shape is not given.

  FIG.1 and FIG.2 shows the outline | summary of the heat insulation panel 1 which concerns on one Embodiment of this invention. The heat insulation panel 1 is configured such that a foamed resin heat insulating material 2 molded into a plate shape and a film-shaped exterior material 3A are bonded to at least one side surface of the plate surface. In this embodiment, it is set as the structure by which film-form exterior material 3A * 3B is bonded together on the both sides | surfaces of the foamed resin heat insulating material 2. FIG.

  Moreover, the foamed resin heat insulating material 2 is molded as a heat insulating panel having a predetermined thickness by foaming and curing a foaming raw material such as commercially available polyurethane.

  The film-shaped exterior materials 3A and 3B are aluminum foil, resin film, paper, and the like. Moreover, what gave the laminate for exhibiting a specific function on the surface etc. is used. For example, when it is used as a heat insulating material for the back of a hut, it is possible to use a film-shaped exterior material 3A or 3B that is provided with a low radiation laminate that exhibits a heat shielding function.

  In addition, the surfaces 1A and 1B of the heat insulating panel 1 are each provided with a concavo-convex shape constituting a regular appearance pattern. In this embodiment, the surfaces 1A and 1B are arranged regularly, that is, at regular intervals in the vertical and horizontal directions. Surfaces 1 </ b> A and 1 </ b> B are configured as concave and convex surfaces from substantially rhombus-shaped convex portions 11 and 11 and groove-shaped concave portions 12 that are continuous with each other so as to surround the convex portions 11 and 11. .

  Moreover, as shown in FIG.2 and FIG.3 (a), as for the uneven surface of this surface 1A, in the location of the recessed part 12, while the film-form exterior material 3A and the foamed resin heat insulating material 2 are dented integrally, other than that The part is configured to float integrally as the convex portions 11 and 11, and an external appearance with a three-dimensional feeling is configured. Thus, by making the appearance with a three-dimensional effect, the three-dimensional effect affects the vision, and an effect of making the wrinkles 13 less noticeable can be obtained.

  In addition, in order to comprise this external appearance with a three-dimensional effect, it is preferable that the depth of the recessed part 12 shall be 0.5 mm-5 mm. Furthermore, in addition to the fact that the concave portion 12 is actually configured in a groove shape, a three-dimensional effect is configured, and the surface of the film-shaped exterior material 3A is actually printed with a regular pattern to create a three-dimensional effect. It is good also as a structure which exhibits a three-dimensional feeling, although it is a flat surface.

  Moreover, as shown in FIG.2 and FIG.3 (a), when the void 21 is formed in the foamed resin heat insulating material 2, the foamed resin heat insulating material 2 does not exist in the location of this void 21. FIG. As a result, there is no support for the film-shaped exterior material 3A from the back side, and the film-shaped exterior material 3A enters the void 21 and the wrinkles 13 are formed on the surface of the film-shaped exterior material 3A. It will be.

  In this case, as shown in FIG. 3A, wrinkles 13 appear in the convex portion 11, but as shown in FIG. 1, the contour shapes of the convex portions 11 and 11 and the concave portion 12 are regular with a stereoscopic effect. As a result, the wrinkles 13 (FIG. 3A) can be made inconspicuous.

  That is, as compared with the wrinkles 13 that are expected to appear, the number and the total area of the protrusions 11 greatly exceed (for example, at least twice or more). It is possible to eliminate it.

  On the other hand, as shown in FIG. 3B, if a flat appearance with no irregularities is formed as in the surface 1C, the wrinkles 14 and 14 scattered on the surface 1C are the only thing that catches the eye. It becomes a place, and it will stand out. As a result, there is a concern that the impression of the defect of the product is given or the aesthetic appearance is impaired.

  Furthermore, as shown in FIG. 1, since a regular appearance pattern is formed from the substantially rhombic convex portions 11 and 11 and the continuous groove-like concave portion 12, it is possible to configure the external appearance design with this pattern. Thus, it is possible to realize a foamed resin heat insulating panel that also has aesthetics. In addition, about the shape of the convex part 11, what is called a geometrical figure etc. which uses a triangle, a square, a polygon, a circle | round | yen etc. as a raw material other than a substantially rhombus shape is considered.

  In addition, even if wrinkles occur, the wrinkles are inconspicuous, so that the probability that a foamed resin heat insulation panel that is difficult to allow in terms of product appearance will be manufactured can be reduced. It becomes possible. Accordingly, the production yield is improved, and it is possible to reduce the waste of product raw materials and the reduction of disposal, and it is possible to realize eco-friendly manufacturing.

  In addition, as shown in FIG. 3A, the size (area, grid) of the convex portion 11 to be formed is confirmed, for example, by a void 21 having a maximum width of 1 cm in a prototype test. When 13 can be formed, the probability of arranging the wrinkles 13 inside the convex portion 11 can be increased by designing the convex portion 11 having a width larger than 1 cm.

  Thereby, the probability that the wrinkles which are conspicuous because the shape is larger than the convex part 11 can be reduced, and the foamed resin heat insulation panel which is difficult to be permitted in the appearance of the product will be manufactured. Probability can be reduced. Accordingly, the production yield is improved, and it is possible to reduce the waste of product raw materials and the reduction of disposal, and it is possible to realize eco-friendly manufacturing.

  Further, as shown in FIG. 3 (a), the shape of the convex portions 11 and 11 exerts the three-dimensional effect and makes the wrinkle 13 inconspicuous, so that the maximum width (the maximum of one geometrical figure in a plan view). It is preferable to make it a geometric figure having a maximum width of 2 cm to 8 cm, more preferably a maximum width of 4 cm to 8 cm. This is because if the maximum width is less than 1 cm, it is difficult to obtain a three-dimensional effect, and if the maximum width is greater than 10 cm, there is a concern that the wrinkle 13 may be noticeable when placed in the convex portion 11.

  Moreover, as shown to Fig.3 (a), when the unevenness | corrugation is formed in the surface 1A * 1B of the heat insulation panel 1, the contact area of 3 A of film-form exterior materials and the foamed resin heat insulating material 2 is FIG. Compared with the thing without the unevenness | corrugation shown by b), it can ensure large. Thereby, the adhesive strength with respect to the foaming resin heat insulation panel of 3 A of film-form exterior materials is strengthened, and the effect that peeling of 3 A of film-form exterior materials becomes difficult is acquired.

  Moreover, as shown in FIG. 1, when the surface 1A * 1B of the heat insulation panel 1 is provided with an uneven shape, each heat insulation panel 1 is overlapped when a plurality of heat insulation panels 1 are stacked at the time of delivery to the construction site. The frictional resistance that can occur between the panels 1 can be kept low.

  Thereby, when trying to lift only one piece of the heat insulation panel 1 on the upper side at the time of carrying in, etc., it is possible to avoid the inconvenience that the heat insulation panel 1 below is taken and moved together. it can. This is because, particularly when the heat insulating panel 1 is large, the weight of the heat insulating panel 1 is increased, and it is assumed that the contact area is wide and the frictional resistance is increased. Considering the ease of handling in this case, the effect is extremely effective.

As described above, as shown in FIGS. 1 to 3, in the present invention,
A foamed resin heat insulating material 2 molded into a plate shape;
A film-like exterior material 3A bonded to at least one side of the plate surface;
Insulating panel 1 having
A regular pattern is applied to the film-shaped exterior material 3A.

  Thereby, even when the wrinkles 13 are formed on the surface of the film-shaped exterior material 3A due to voids or the like formed in the foamed resin heat insulating material 2, the wrinkles 13 can be made inconspicuous by the pattern. Thus, the beauty of the manufactured heat insulation panel can be secured.

Also, as shown in FIGS.
A regular pattern shall be formed by giving integral uneven | corrugated shape with respect to 3 A of film-form exterior materials, and the foamed resin heat insulating material 2. FIG.

  As a result, an appearance with a three-dimensional effect is obtained, and this three-dimensional effect affects the visual sense, and an effect of making the wrinkles 13 less noticeable can be obtained.

In addition, as shown in FIG.
The regular pattern is formed by regularly arranging a plurality of geometrical figures such as rhombuses,
The size of the geometric figure is such that the maximum width is 1 cm or more and 10 cm or less, more preferably the maximum width is 2 cm or more and 8 cm or less, more preferably the maximum width is 4 cm or more and 8 cm or less.
It is something to do.

  Thereby, the three-dimensional effect of the surface of the heat insulation panel can be obtained and the wrinkles 13 can be made inconspicuous.

Moreover, as a manufacturing method of the heat insulation panel 1 shown in FIG.
A foamed resin heat insulating material 2 molded into a plate shape;
A film-like exterior material 3A bonded to at least one side of the plate surface;
A method of manufacturing a heat insulating panel 1 having
At the time of foam molding of the foam raw material of the foam resin heat insulating material 2 or after foam molding,
It can be set as the manufacturing method which gives a regular pattern from the surface on the opposite side of the foamed resin heat insulating material 2 in 3 A of film-form exterior materials.

  In addition, about the above manufacturing method, it is an example for implement | achieving the structure shown in FIG. 1, and is not limited to this. For example, even in the case where the heat insulation panel is formed in a continuous manner as disclosed in Patent Document 1 described above, in the foam molding process, the both sides of the heat insulation panel are sandwiched by rollers having an uneven surface, and heat insulation is performed. A manufacturing method is also conceivable in which an uneven shape is formed on the panel. Moreover, in addition to actually providing the uneven shape, a form in which a geometric figure is applied to the film-like exterior material by printing or the like in the manufacturing process of the heat insulating panel is also conceivable.

  The heat insulation panel of the present invention can be widely used as a building material for a building such as a house, and can be widely used as a heat insulation panel for use in various places such as a wall portion, a floor portion, and a ceiling portion.
