2. Description of the Related Art Rigid synthetic resin foams are used as various heat insulating materials because of their excellent heat insulating performance. As rigid synthetic resin foam, rigid polyurethane foam, urethane-modified polyisocyanurate foam,
There are phenol foam, extruded polystyrene foam, bead method polystyrene foam, polyethylene foam, etc., but these foams are easily damaged by external impact or have a flexible surface because they are used as structural materials. Certain face materials (soft face materials) or hard face materials such as plywood and gypsum board may be laminated. Here, polyethylene, polypropylene, and polyester sheets are used for the soft surface material from the viewpoint of waterproofing, and carbon black paper, aluminum hydroxide paper, glass nonwoven fabric, and kraft paper that do not allow light to pass through these sheets are used to prevent light deterioration of the foam. A sheet such as paper is laminated. However, laminating different kinds of sheets is not only expensive in itself, but also varies in the quality of the face material itself. As a result, the use of such a face material causes the surface of the obtained insulation board to have a wavy phenomenon. This causes a problem of lowering the product value.

A conventional heat insulating panel for a vending machine, for example, a heat insulating panel used for an inner door of a vending machine, is manufactured by manufacturing a thin plate-like box made of a metal plate (hereinafter, a thin box made of a metal plate). Then, a rigid polyurethane foam stock solution was injected into the inside of the thin box made of a metal plate, and the reaction and foaming of the stock solution were completed in the inside of the box to manufacture the thin box.

As described above, the conventional method of manufacturing a heat insulating panel for a vending machine is a batch method in which the stock solution is poured into each thin box made of a metal plate. It is not a suitable method. Further, when changing the type or size of the vending machine, it is necessary to change the standard of the thin metal plate, and this standard change is extremely difficult. Furthermore, since the above-mentioned heat insulation panel uses a metal plate, there are problems that the weight is large, the handling is inferior, and the assembling work of the vending machine becomes difficult.

On the other hand, in the above-mentioned heat insulating panel, a rigid polyurethane foam which has completed reaction and foaming inside a thin box made of a metal plate is integrated with a metal plate constituting the wall surface of the box. It is technically difficult to peel off the metal plate and the hard urethane foam during recycling. For this reason,
The above-mentioned heat insulation panel is in a situation where it has to be disposed of by landfill without peeling the metal plate and the rigid polyurethane foam after use. However, the landfill location is
At present, it is extremely scarce. Therefore, in this kind of field, development of a recyclable heat insulating panel has been desired.

Means for Solving the Problems The inventors of the present invention have been conducting various studies in order to achieve the above-mentioned object, and have found that a heat-insulating board is made of a transparent polyester sheet containing fine air. It was found that light scattering could suppress the transmission of light, and for vending machine panels, when a face plate with a specific configuration was used instead of a metal plate, excellent rigidity was achieved. Not only does it have high productivity, but it does not use a metal plate as in the case of conventional thermal insulation panels during recycling, so it can be used as fuel as it is, or it can be pulverized, mixed with a binder and compression molded If they could do so, they would be able to use them again for applications such as building materials.

The rigid synthetic resin foam used in the present invention comprises:
Rigid polyurethane foam, urethane-modified polyisocyanurate foam, phenol foam, extruded polystyrene foam, bead method polystyrene foam, polyethylene foam and the like can be used. Among them, those using rigid polyurethane foam, urethane-modified polyisocyanurate foam, and phenol foam, for example, inject the raw materials for producing these foams onto a void-containing polyester-based sheet, and separate the raw materials when the foaming is almost completed. By laminating the void-containing polyester-based sheet, the void-containing polyester-based sheet is integrally molded by the self-adhesiveness of the foam, and a heat insulating board with a double-sided face material is obtained. And, especially, the foam density is 30 to 50 kg /
A rigid polyurethane foam and a urethane-modified polyisocyanurate foam having a size of about m 3 are preferred because they have more excellent compressive strength and adhesiveness to a void-containing polyester sheet. In addition, since these rigid polyurethane foams and urethane-modified polyisocyanurate foams have low thermal conductivity, the thickness of the plate-shaped rigid synthetic resin foam in the present invention, that is, the thickness of the heat insulating board must be reduced. Can be.

The void-containing polyester sheet (hereinafter sometimes simply referred to as a sheet) used in the present invention is a sheet containing a large number of fine voids therein, and the light transmittance is lowered by the voids. . The polyester is used in the present invention in order to satisfy the heat resistance and mechanical strength of the void-containing polyester sheet. The void-containing polyester sheet is solidified by mixing a polyester such as polyethylene terephthalate and polybutylene terephthalate with a polystyrene resin or a polyolefin resin incompatible with the polyester as a void developing agent, and extruding the mixture with an extruder or the like to solidify. Then, it is obtained by performing longitudinal stretching with a roll stretching machine, and subsequently performing transverse stretching with a tenter. Further, for the purpose of lowering the light transmittance, inorganic particles such as titanium dioxide, calcium carbonate, barium sulfate and the like can be added to the sheet.

The void-containing polyester sheet has a moderate elasticity (softness) due to the presence of the voids.
As a result, the heat insulation board of the present invention has the ability to absorb external impact and has excellent rigidity. Further, since the sheet has a cavity, the sheet has a lower thermal conductivity than that without the sheet. In the heat insulating board in which the face materials are laminated, the heat insulating property is ensured by the foam having low thermal conductivity in the thickness direction, but the heat may escape through the surface of the face material. The heat insulation board of the present invention is also excellent in heat insulation of heat transmitted on the surface.

Although the appropriate void content of the sheet used in the present invention varies depending on the thickness of the sheet, the void content in the usable range is about 10 to 50% by volume. 10
When the content is less than the volume percentage, not only the elasticity is reduced, but also the light transmittance is increased, and the meaning of containing a void in the sheet is reduced in terms of light deterioration of the foam. If it exceeds 50% by volume, the elasticity and light transmittance are improved, but the mechanical strength of the sheet is reduced, and as a result, the rigidity of the heat insulating board tends to be insufficient.

Although the appropriate thickness of the sheet varies depending on the void content, the usable thickness of the sheet is 50 to 300 μm, preferably 75 to 200 μm. If it is less than 50 μm, it is difficult to protect the foam from impact, and if it is more than 300 μm, the unit price of the sheet increases, which is uneconomical. Preferably, at least the laminated surface of the sheet with the rigid synthetic resin foam is subjected to a surface treatment such as corona discharge so that the adhesive strength between the sheet and the rigid synthetic resin foam is increased.

The heat insulating board of the present invention may be a laminated rigid synthetic resin foam having laminated polyester sheets containing voids on both sides, or may be laminated on one side. When only one surface is laminated, another surface material may be laminated on another surface of the foam, or may not be laminated. This is because such thermal insulation boards are stored and transported in a stacked manner, so that even if only one side is used, it is effective to prevent light deterioration of the foam. In addition, during installation, people may fall on the insulation board or things may drop, but if the polyester sheet containing voids is laminated on at least that surface, protect the insulation board from the impact.

Than the synergy of
Despite not using a metal plate, it has substantially the same rigidity as a conventional heat insulating panel using a metal plate. Further, since no metal plate is used, the weight can be significantly reduced. Furthermore, since the frame can be easily removed, it has excellent recyclability. Furthermore, the plate-shaped rigid synthetic resin foam, the face material, and the frame are separately mass-produced and assembled, or the production of the foam and the attachment with the face material are simultaneously performed in a long state. Since it can be manufactured by cutting to a predetermined size and assembling with a mass-produced frame, extremely high productivity can be obtained as compared with the conventional manufacturing of a heat insulating panel.
