Abstract

(57) [Abstract] [Problem] To make a plate of a heat insulating panel for a commercial refrigerator at low cost. SOLUTION: A 55% aluminum-zinc alloy-plated steel sheet coated with epoxy resin on both sides, or an inner side coated with epoxy resin and an outer side coated with a service coat are both 1
It is completed by coating once and baking once, and it is used only in areas not exposed to sunlight and only in places where beauty is not required, that is, only in the back plate. In this way, it is possible to make the cost lower than that of the conventional double-coating and double-baking, by the amount used. A conventional colored iron plate is used in the place exposed to sunlight. Moreover
As we use 55% aluminum zinc alloy plated steel sheet,
Epoxy resin or service coat alone does not deteriorate performance such as corrosion resistance.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure of a plate of a heat insulation panel for a refrigerator for business use.

[0002]

[Prior art]

 Conventionally, color iron plates, that is, colored zinc iron plates, have been used for the surfaces of heat insulation panels of commercial refrigerators and freezers. Conventionally, this panel needs to be applied twice and baked twice. First, apply the undercoat on both the front and back. This basecoat is a service coat. Then, bake. Furthermore, increase the amount of paint on the surface, thicken the coating layer, apply a top coat, and bake to finish. The surface part has a beautiful finish, but it is expensive because it is applied twice and baked twice.

[0003]

[Problems to be solved by the device]

 In the present invention, a so-called galvalume steel plate is used as the back plate, which is coated with epoxy resin on the inside and epoxy resin or a service coat on the outside.

[0004]

[Means for Solving the Problems]

 The present invention has a structure of a galvanium steel plate with a plating layer, the inside of which is coated with epoxy resin, and the outside of the back plate that is not exposed to the sun's rays is an inexpensive coating. , And also the outer part of the back plate, that is, both sides, the structure of the board of the heat insulation panel such as the refrigerator for commercial use which is coated with epoxy resin, and the inner part is coated with epoxy resin, and the outer part of the back plate is coated with epoxy resin. The present invention relates to a structure of a heat insulating panel plate for a commercial refrigerator or the like, which is provided with a service coat which is cheaper than resin.

[0005]

[Embodiment of the invention]

 Galvalume steel sheets are used only on the non-lighted parts of the heat insulation panels of commercial refrigerators. In the first embodiment, both surfaces are coated with epoxy resin. In this case, epoxy resin is applied to both sides in the same manner as the undercoat and baked. That is, since the coating is performed once and baked once to finish, the number of steps is reduced and the cost is reduced as compared with the conventional double coating and baking.

[0006] Epoxy resin adheres well to adhesives and urethanes, is less likely to become familiar with and cause poor adhesion, and the galvalume steel sheet itself has excellent corrosion resistance. Therefore, epoxy resin and a service coat alone make a color iron plate. Compared with, the performance such as corrosion resistance does not deteriorate.

[0007] In the part of the refrigerator, where the color iron plate is not used, the color iron plate is used, and only the galvalume steel plate and the epoxy resin are used, that is, the place not exposed to the sun rays or the second finishing coating is not required. That's where the unseen, or where beauty is not so demanding, is there.

In the figure, FIG. 1 shows a galvalume steel plate in the center, 2 a zinc aluminum alloy plating layer, and 3 an epoxy resin layer.

Further, as another embodiment shown in FIG. 2, the so-called service coat 4 is cheaper than the epoxy resin, and if this is used on the front side, it can be produced at a lower cost. In this case, the Galvalume steel plate 1 is coated with the service coat 4 on the front side and the epoxy resin 3 on the inner side. Also in this case, one side should be coated with epoxy resin and one side should be coated with a service coat and baked to finish. That is, one application and one baking are sufficient.

FIG. 3 shows a conventional example, 5 is an iron plate, 6 is a plated layer, 7 is an undercoat service coat, and 8 is an overcoat layer.

[0011]

[Effect of the invention]

 Epoxy resin is weak against sunlight but is inexpensive and adheres well to the urethane core. However, epoxy resin can be used for the shaded part facing the wall of the refrigerator. Further, in the first embodiment, not both sides, but both sides are coated with the epoxy resin, so that workability is good. Further, of course, the present invention is inexpensive because there is no finish coating process for the color iron plate.

[0012] As described above, the color iron plate is not used for the entire part, and a part of the coating is inexpensive, that is, a galvanized steel plate with one coating and one baking is required. Therefore, the structure can be constructed at a lower cost than the conventional method having a finish coating process. . In addition, the galvalume steel sheet has corrosion resistance, and the corrosion resistance does not deteriorate.

In addition, the service coat of the second embodiment has an advantage that colors can be freely selected, and can be manufactured at a lower cost than double-sided epoxy resin.
