The present invention relates to a heat insulating wall of the GFP / GFP polyurethane foam used in the heat insulating wall of the refrigerator or the heat insulating wall of the building molded of GFP (gas filled panel) or GFP + polyurethane foam. Looking at the conventional case, it is known that the Lawrence Berkely Laboratory of the United States contributed a lot to the performance of the GFP as a technology regarding the material of the GFP itself.

In general, GFP is a heat insulator that minimizes the thermal conductivity of the entire volume by filling a gas such as krypton, which has much less thermal conductivity than air, instead of general air, in a predetermined space such as a vinyl tube.

Although there have been many studies on the GFP itself, there has been no study on the specific method of using the GFP.

Therefore, a commonly used example is the same as FIG.

A plastic film film (1) which prevents gas leakage from the outside to the inside or the inside to the outside,

A baffle (4) of indirect media having a low emissivity between the metal thin film (2) coated inside of the plastic film film (1) of low emissivity material to block the emissivity and between the metal thin film (2). and,

Between the metal thin film (2) and the baffle (4) located inside the plastic film film (1) was composed of a heat insulating wall including a gas (3) having a low thermal conductivity to minimize the thermal conductivity from the high temperature portion to the low temperature portion.

However, there has been no specific research and development on the structure and form of GFP that can replace the existing insulation in the refrigerator until now.

In addition, the characteristics of the current GFP is vulnerable to mechanical strength, it does not maintain a constant strength in the refrigerator because it is deformed when the external pressure is applied.

In addition, the GFP bursts due to severe external shocks, and the insulation performance of the GFP drops sharply, or the refrigerator may not be able to support the weight of the refrigerator. . Accordingly, the present invention is to replace the CFC insulator to solve the problems described above, by simultaneously applying the GFP and PU to the insulation wall of the refrigerator or building in a composite form of GFP or GFP and PU (polyurethane foam) An object of the present invention is to provide a heat insulator of GFP / GFP PU to obtain the required heat insulation performance and mechanical strength.

As one feature for achieving the object of the present invention, by forming a composite form of GFP or GFP and PU in the outer frame of the metal, plastic, and the inner part of the insulation sealant (Sealant) and the inner phase (ABS) plastic by molding sequentially It can be used as a heat insulation wall on refrigerators and building side walls.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

2 and 3 illustrate a GFP insulation material 20 positioned inside the outer frame 10 of the refrigerator door made of metal or plastic, and an inner wound ABS for fixing the door inner gasket and the gasket as a first embodiment of the present invention. 70,

The frame 30 supporting the door inner image and the gasket and the fixing screw 60 are fastened to the frame 30 using the inner image 70.

In the intermediate position of the GFP heat insulating material 20, the heat-insulating sealant 40 for adhering two or more GFP heat insulating materials to each other to prevent heat leakage, and the refrigerator door part is generally a part that receives less mechanical stress than other parts. The embodiment is to be applied to the door of the refrigerator.

In particular, as shown in FIG. 3, when the door inner gasket and the gasket are installed, the mechanical damage caused by the external shock in the assembly line in the GFP is specially adopted to prevent the occurrence of puncture or pin holes. And the door inner frame and the gasket support frame.

4 is a second embodiment having a composite of a GFP and a PU used for the side part of the refrigerator or the side wall of the building.

In FIG. 4, after the PU 89 and the GFP heat insulating material 20 are sequentially positioned inside the outer frame 10 of the side part of the refrigerator, the heat insulating sealant is adhered to the GFP heat insulating material 20 to prevent leakage of heat. 40) and an inner phase (ABS 70) is bonded to the heat insulating sealant.

That is, the heat insulation wall is applied to the side of the refrigerator or the building wall, it is possible to obtain the heat insulation performance and mechanical strength required by using the GFP and PU at the same time.

FIG. 5 is to prevent the gas from leaking due to excessive tension of the GFP insulation material at the refrigerator or the building wall, that is, the corner portion of FIG. 4 and constitutes the GFP insulation material 20 in a pleated shape at the corner portion.

In addition, it is possible to save the heat insulating material by the volume located between the round solid line and the dotted line in FIG.

In other words, by removing the tensile force applied to the corner portion of the GFP in the form of pleats to prevent gas leakage.

As such, the present invention has the effect of replacing the existing CFC insulator.
