The present invention relates to a cryogenic insulation panel, and more particularly, it is preferably used for storage facilities (LNG vessels) for storing state substances having a very low boiling point such as liquefied natural gas (LNG), liquefied helium, liquefied nitrogen, etc. In particular, the present invention relates to an ultra-low temperature insulation panel for providing excellent heat insulation, as well as being easy to manufacture and inexpensive by providing a multi-layered heat insulating layer including a first heat insulating space of an air layer and a second heat insulating layer of a heat insulating material or a heat insulating plate, and both.

Cryogenic insulation panels are used in storage facilities that liquefy and store liquefied natural gas, such as liquefied natural gas (LNG), liquefied helium, and liquefied nitrogen.

On the other hand, LNG vessels, an example of storage facilities, store and transport LNG of colorless, transparent cryogenic liquid whose natural gas, which contains methane as its main component, is cooled to a temperature of -163 ° C and its volume is reduced to one hundredth.

In other words, such LNG vessels are designed to transport large quantities of LNG, which is used as a major energy resource, from the production site to the demand site in recent years. Such LNG vessels have a stand-alone and membrane type having a tank capable of withstanding ultra-low temperatures of -163 ° C. Divided into

On the other hand, cryogenic insulation panels should be used in storage facilities such as LNG vessels and large tanks for storing LNG on the ground. Such cryogenic insulation panels require excellent insulation performance with low heat transfer rate, and at the same time the overall aspect of the insulation panels. Requires physical strength.

That is, such ultra low temperature insulation panels should be provided with a strength that does not cause cracks withstand wrinkles and stress caused by the temperature difference between the inside and outside of the container of the storage facility, and when laminated construction between the insulation panels Thickness precision must also be maintained to avoid gaps.

On the other hand, one of the materials used for the material of such cryogenic insulation panels is a rigid polyurethane foam (polyurethane foam), such a polyurethane foam is known to have the most excellent low-temperature insulation performance, and therefore the It is mainly used as cryogenic insulation for liquefaction storage facilities.

In other words, polyurethane foam is a porous product made of polyurethane as a skeleton, and the polyurethane obtained by the reaction of isocyanate compound and glycol is used as a constituent material, and isocyanate and a bridge binder as constituents. It is commonly used as a foaming product made by mixing volatile solvents such as carbon dioxide and freon produced by reaction with water and using a blowing agent.

However, such a polyurethane foam can control the bulk density of the foam relatively freely, can be easily foamed in the field, and depending on the degree of rigidity, super soft, soft (semi-hard) ( 가지), it has a variety of hardness, such as hard, in particular, the rigid foam is used as a cryogenic heat insulating material because of the rigid (剛性), good heat insulating properties and low temperature properties.

On the other hand, ultra-low temperature insulation material using polyurethane foam corresponds to the strength that can withstand the wrinkles and stresses caused by the temperature difference between the inside and outside of storage facilities, that is, LNG vessels, etc. Is embedded in a rigid polyurethane foam, and a glass fiber reinforced rigid polyurethane foam (R-PUF) is mainly used in recent years.

At this time, the glass fiber used as the material of the cryogenic insulation panel is a mineral fiber made of molten glass as a fiber, and its characteristics are high temperature, non-burning, absorptive and hygroscopic. It is small and does not corrode because of its chemical durability, especially tensile strength is low, elongation is low, electrical insulation is large, wear resistance is low, specific gravity is 2.2 times of nylon, 1.7 times of cotton, heat insulation, cold insulation Mainly used for).

Therefore, at present, as a heat insulation panel for cryogenic storage facilities such as LNG ships, a heat insulating material of a glass fiber-containing rigid polyurethane foam (hereinafter referred to as 'R-PUF' or simply a foam) is laminated and used as a cryogenic insulation panel. .

On the other hand, Figures 1 to 3 shows a cryogenic insulation panel that uses such R-PUF, that is, an insulation panel applied to the LNG vessel.

For example, in FIG. 1, the heat insulation panel 100 using R-PUF is illustrated, and in FIG. 2, the aluminum foil 114 is bonded between the glass fiber body 110, that is, the glass fiber 112. The glass fiber body 110 bonded as shown is shown.

That is, the heat insulation panel 100 of FIG. 1 is produced by R-PUF including the glass fiber body 110 of FIG. 2 through a process such as foaming-processing-adhesive-pressing.

On the other hand, Figure 3 is a schematic perspective view showing the structure of the cryogenic storage facility, that is, the membrane of the LNG vessel as the insulation panel 100 using such an R-PUF.

That is, as shown in FIG. 3, a plurality of insulation panels 100 are stacked and disposed on the membrane hull 120 of the LNG vessel, which is a storage facility, and stored in the skin portion 100a of the insulation panel 100. The stainless membrane 130, which is a primary barrier that is in direct contact with the transported LNG and withstands the shrinkage stress and impact caused by cryogenic temperatures, is mounted.These insulation panels 100 are flat panels 100b surrounding the R-PUF. ) Is provided, and the frame is connected and fixed by a joint or the like.

However, most of the conventional cryogenic insulation panels known to date constitute a panel using R-PUF as a base material, and they are constructed in an cryogenic storage facility, which satisfies the thermal insulation to some extent, even though it includes glass fiber, and is a substantial low temperature facility. There is a lot of shape maintenance due to wrinkles and impact stress caused by temperature difference between internal and external systems.

For example, as schematically shown in FIG. 4, a thermal insulation panel 100 using an R-PUF between a storage facility, for example, an LNG vessel membrane shell 120 and a stainless membrane 130 is now stacked. In the structure up to, a considerable pressure (arrow) is applied in order to store LNG at a temperature of -163 ° C, which is an ultra low temperature, and when the stainless membrane 130 is subjected to a substantial high pressure, the insulation panel 100 is pressed. As a result, the spacing (D) with the outer shell 120 is reduced, so that normal cooling by heat transfer is not achieved.

In addition, the cryogenic insulation panel using R-PUF has a high production cost.

On the other hand, it is well known that blocking the heat transfer by forming a heat insulating space of the air layer between different temperature ranges is the largest heat insulating effect.

However, until now, no insulation panel having an insulation space using an air layer has been proposed in the cryogenic insulation panel so far, which is impossible to maintain structural strength while maintaining an insulation space of an air layer using conventional R-PUF alone. Because it is.

Accordingly, there has been a need for a cryogenic insulation panel having a thermal insulation space of the air layer to maximize the insulation effect and maintain strength even when used in an cryogenic storage facility.

In addition, there has been a demand for a cryogenic insulation panel having a multilayer insulation layer.

The present invention has been made in order to solve the above-mentioned conventional problems, the object of the present invention is preferably a storage facility for storing a gaseous state of a low boiling point, such as LNG, liquefied helium, liquefied nitrogen, such as LNG ships, etc. In particular, the present invention provides an ultra-low temperature insulation panel that has excellent thermal insulation and is easily combined with a rigid polyurethane foam as a panel having an insulation space filled with air.

As a technical aspect for achieving the above object, the present invention has a plurality of vertical walls and an air insulation space provided to enable insulation between the vertical walls, the upper and lower portions of the vertical walls are integral Panel base material consisting of a synthetic resin plate-like as a whole unit cells formed with openings therebetween connected to each other; And,
