[0001] The utility model relates to the technical field of heat insulation panels, in particular to a partition packaging bag and a vacuum heat insulation panel thereof. Background Art

[0002] With the progress and development of society, the demand for energy-saving materials is also increasing. More and more vacuum insulation panels are used in refrigerators, incubators, cold chain transportation and other fields. The demand for vacuum insulation panels in various industries is increasing, and the performance requirements and environmental adaptability are also getting higher and higher.

[0003] Current packaging bags are usually single-chamber structures, which make it difficult to store core materials with different properties at the same time. In addition, once the packaging bag is punctured, external air will penetrate into the entire single chamber of the packaging bag, affecting the performance of the vacuum insulation panel. Utility Model Content

[0004] Based on this, it is necessary to provide a partition packaging bag and a vacuum insulation panel thereof to address the problem that it is difficult to store core materials with different properties at the same time, and once the packaging bag is punctured, external air will penetrate into the entire single chamber of the packaging bag.

[0005] The utility model proposes a partitioned packaging bag, which comprises: a packaging bag body, on which a sealing area is provided for placing a core material into an inner cavity of the packaging bag body and sealing the packaging bag body; a separator, at least one of which is provided inside the packaging bag body and is used to separate the inner cavity of the packaging bag body into a plurality of independent chambers, and the separator comprises: a first heat-sealing layer for heat-sealing connection with the packaging bag body; a first protective layer for preventing puncture and air penetration; and a second heat-sealing layer for heat-sealing connection with the packaging bag body.

[0006] As a further improvement of the present invention, the first protective layer is arranged between the first heat sealing layer and the second heat sealing layer.

[0007] As a further improvement of the present invention, the first protective layer includes: an anti-puncture layer and a first barrier layer for preventing air penetration.

[0008] As a further improvement of the present invention, the puncture-resistant layer is a PA puncture-resistant layer; or the puncture-resistant layer is a PET puncture-resistant layer.

[0009] As a further improvement of the present invention, the first barrier layer is an aluminum foil first barrier layer; or the first barrier layer is a VMPET first barrier layer; or the first barrier layer is an EVOH first barrier layer.

[0010] As a further improvement of the utility model, the packaging bag body comprises, from outside to inside, a second protective layer, a medium barrier layer, a high barrier layer and a third heat-sealing layer.

[0011] As a further improvement of the present invention, the middle barrier layer is a VMPET middle barrier layer.

[0012] As a further improvement of the utility model, the high barrier layer is an aluminum foil high barrier layer.

[0013] The utility model also proposes a vacuum insulation panel, comprising: the above-mentioned partition packaging bag; multiple core materials, the multiple core materials correspond one-to-one to the multiple independent chambers, and the multiple core materials are respectively arranged in the corresponding independent chambers, and the core material located on the outside is provided with a groove, and a getter is arranged in the groove.

[0014] As a further improvement of the present invention, the groove is provided on a side of the corresponding outer core material away from the adjacent core material.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. The utility model divides the inner cavity of the packaging bag body into at least two independent chambers by arranging at least one partition in the inner cavity of the packaging bag body. Core materials of different materials can be placed inside each independent chamber, so that a multi-chamber composite vacuum insulation panel with better performance can be combined, which is suitable for various working conditions and more flexible to use.

When the surface or part of the vacuum insulation panel is damaged by collision or extrusion, the vacuum degree in the corresponding independent chamber will decrease. However, due to the existence of the partition and the support of the core material, it is difficult for air to penetrate into other independent chambers, and the vacuum degree in other independent chambers is slightly affected. Therefore, the vacuum insulation panel can still maintain good insulation performance. Compared with the existing single-chamber insulation panel, it has better puncture resistance and collision resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0028] like Figure 1-5 As shown, the embodiment of the utility model provides a vacuum insulation panel, which includes: a partition packaging bag and a plurality of core materials 3 placed inside the partition packaging bag. The drawings in this embodiment mainly take a vacuum insulation panel with three independent chambers as an example.

[0029] like Figure 2As shown, the partitioned packaging bag includes: a packaging bag body 1 and a separator 2. A sealing area is provided on the packaging bag body 1, and the sealing area is used to put the core material 3 into the inner cavity of the packaging bag body 1 and seal the packaging bag body 1. In other words, the packaging bag body 1 is a three-circle sealed structure, and an opening is provided on one side of the packaging bag body 1, and the opening is the sealing area. The core material 3 can be put into the inner cavity of the packaging bag body 1 from the sealing area. After the core material 3 is placed, the sealing area can be sealed to form a whole with the core material 3 and the packaging bag body 1. The separator 2 is arranged inside the packaging bag body 1, and is used to divide the inner cavity of the packaging bag body 1 into a plurality of independent chambers, and the core material 3 can be placed inside each independent chamber.

[0030] like Figure 3 As shown, the packaging bag body 1 includes, from outside to inside, the second protective layer 11, the medium barrier layer 12, the high barrier layer 13 and the third heat sealing layer 14. It should be noted that the packaging bag body 1 can be made of two identical films, and each film includes, from outside to inside, the second protective layer 11, the medium barrier layer 12, the high barrier layer 13 and the third heat sealing layer 14. By pressing the three edges of the third heat sealing layer 14 in the two films together and reserving a sealing area, a three-circle sealed packaging bag body 1 can be made, that is, the packaging bag body 1 also includes, from outside to inside, the second protective layer 11, the medium barrier layer 12, the high barrier layer 13 and the third heat sealing layer 14.

[0031] After the core material 3 is placed, each independent chamber in the packaging bag body 1 is simultaneously vacuumed, and then the edges of the two third heat-sealing layers 14 corresponding to the sealing area are heat-pressed and sealed. When the vacuum insulation panel made in this way is partially damaged by collision or extrusion on the surface or part, only the vacuum degree in the independent chamber that is collided will decrease, but the vacuum degree in other independent chambers will be slightly affected. Therefore, the vacuum insulation panel can still maintain good insulation performance.

[0032] Among them, the second protective layer 11 is mainly used to reduce the erosion and damage of the external environment to the structure of the packaging bag body 1. The material of the second protective layer 11 can be PA material, which is generally PA plastic (nylon, polyamide). Nylon material has good toughness, puncture resistance and tensile resistance, which is beneficial to protect the packaging bag body 1. Of course, the second protective layer 11 can also be made of other suitable materials.

[0033] The middle barrier layer 12 is mainly used to initially block the air in the external environment, preventing the external air from entering the inner cavity of the packaging bag body 1, so as to maintain the vacuum degree in the inner cavity of the packaging bag body 1, and further maintain the performance of the vacuum insulation panel. Specifically, the middle barrier layer 12 is mainly used to block oxygen and water vapor in the air.

[0034] It should be noted that the middle barrier layer 122 preferably uses VMPET material. VMPET refers to polyester aluminum-plated film, which is generally used as a protective film on the packaging of dry and puffed foods such as biscuits and some medicines and cosmetics. The aluminum-plated film has the characteristics of both plastic film and metal. The aluminum plating on the surface of the film has the function of shading and preventing ultraviolet radiation, which not only prolongs the shelf life of the contents, but also improves the brightness of the film, so that it can replace aluminum foil to a certain extent. It is also cheap, beautiful and has good barrier properties. Therefore, the application of aluminum-plated film in composite packaging is very extensive, mainly used in the packaging of dry and puffed foods such as biscuits and some medicines and cosmetics.

[0035] The barrier layer has medium and high grades, and has relatively unified standards in the industry. For example, high barrier means that the water vapor permeability per square meter of film within 24 hours is less than 1 mg, or the oxygen permeability per square meter of film within 24 hours is less than 1 ml. Medium barrier means that the water vapor permeability per square meter of film within 24 hours is less than 10 mg, or the oxygen permeability per square meter of film within 24 hours is less than 10 ml.

[0036] Similarly, the high barrier layer 13 is also mainly used to further block the air in the external environment, preventing the external air from entering the inner cavity of the packaging bag body 1, so as to further maintain the vacuum degree in the inner cavity of the packaging bag body 1, and further maintain the performance of the vacuum insulation panel. Specifically, the high barrier layer 13 is also mainly used to block oxygen and water vapor in the air.

[0037] The material of the high barrier layer 13 can be aluminum foil film, which is usually used as the high barrier layer 13 and compounded in the middle layer to block the penetration of water vapor and oxygen. Because aluminum foil is a dense metal layer, its barrier property is better than that of aluminum-plated film and vapor-deposited film.

[0038] The third heat-sealing layer 14 is mainly used for heat-sealing connection to seal the core material 3 in the inner cavity of the packaging bag body 1. The third heat-sealing layer 14 can be made of PE material, that is, polyethylene material. Polyethylene material is a thermoplastic plastic with a certain degree of crystallinity and strong intermolecular force, so it has good heat-sealing performance. Of course, the third heat-sealing layer 14 can also be polypropylene or other suitable materials. The second protective layer 11, the medium barrier layer 12, the high barrier layer 13 and the third heat-sealing layer 14 are connected by adhesive bonding.

[0039] In addition, if Figure 1 and Figure 2As shown, the separator 2 is arranged inside the packaging bag body 1, and is used to divide the inner cavity of the packaging bag body 1 into a plurality of independent chambers. Among them, the number of the separator 2 is at least one, so that the separator 2 can divide the inner cavity space of the packaging bag body 1 into at least two independent chambers, and the plurality of core materials 3 correspond to the plurality of independent chambers one by one, and the plurality of core materials 3 are respectively arranged in the corresponding independent chambers.

[0040] It should be noted that the core material 3 can be divided into glass fiber insulation board, silica powder insulation board, PET fiber insulation board, etc. according to the type. Each insulation board has its own advantages and disadvantages due to the different materials of the core material 3. For example, the thermal conductivity of glass fiber insulation board is low, but the thermal conductivity increases rapidly during use. The initial thermal conductivity of silica powder insulation board is low due to the porous core material 3 structure, but the growth is slow during use. The vacuum insulation board made of PET fiber insulation board is relatively thin due to its low density. And PET fiber insulation board has good hardness. The above types of core materials 3 have their own advantages and disadvantages, and they cannot be mixed due to the structural differences of the materials.

[0041] Since the partition 2 divides the inner cavity space of the packaging bag body 1 into multiple independent chambers, each independent chamber can be filled with a core material 3 of the same or different materials. Therefore, the vacuum insulation panel can be made into a composite multi-chamber vacuum insulation panel with better performance, which can be applied to a variety of working conditions and is more flexible and convenient to use.

[0042] It should be noted that vacuum insulation panels are usually used to isolate the spread of heat. When in use, there is a certain temperature difference between the two sides of the vacuum insulation panel. Usually, on the side with higher temperature, the activity of gas molecules is higher and the penetration rate is faster. For single-cavity vacuum insulation panels made of traditional single-cavity packaging bags, after the gas penetrates into the interior of the single-cavity packaging bag, the vacuum degree inside the single-cavity vacuum insulation panel will decrease as a whole, thereby affecting the overall thermal conductivity of the single-cavity vacuum insulation panel. For vacuum insulation panels made of partition packaging bags, even if the gas penetrates into the outermost independent chamber, causing the vacuum degree of the outermost independent chamber to decrease, due to the presence of the partition 2, the gas molecules that penetrate into the outer independent chamber are difficult to penetrate into the adjacent independent chambers, which reduces the speed of the vacuum degree decrease in the independent chamber away from the high-temperature area, so that the overall thermal conductivity of the vacuum insulation panel can be maintained at a low level for a long time, and the service life of the vacuum insulation panel can also be extended.

[0043] like Figure 4As shown, further, the separator 2 includes: a first heat-sealing layer 21, a first protective layer 22, and a second heat-sealing layer 23. Among them, the first protective layer 22 is arranged between the first heat-sealing layer 21 and the second heat-sealing layer 23. Since the first heat-sealing layer 21 and the second heat-sealing layer 23 are mainly used for heat-sealing connection with the packaging bag body 1, it is more reasonable to arrange the first protective layer 22 between the first heat-sealing layer 21 and the second heat-sealing layer 23, so as to facilitate the heat-pressing sealing of the first heat-sealing layer 21 and the second heat-sealing layer 23 with the third heat-sealing layer 14 on the packaging bag body 1. Specifically, the edges of the first heat-sealing layer 21 and the second heat-sealing layer 23 can be heat-pressed and sealed with the third heat-sealing layer 14 of the packaging bag body 1, so that the separator 2 can be fixed in the inner cavity of the packaging bag body 1, making the arrangement of the separator 2 more secure and stable, and thus can better play the role of separation and installation.

[0044] In addition, the first protective layer 22 is mainly used to prevent puncture and air penetration, so that when the independent chamber close to the outside of the vacuum insulation panel is hit or penetrated by air, the first protective layer 22 can protect the adjacent independent chamber. Specifically, the first protective layer 22 includes: an anti-puncture layer 221 and a first barrier layer 222. Specifically, the first barrier layer 222 is mainly used to block the penetration of oxygen and water vapor in the air.

[0045] It should be noted that the material of the separator 2 can be divided into two categories, one of which is an aluminum-plastic composite film containing a metal component. Specifically, the material of the first heat-sealing layer 21 can be a PE material, and the material of the anti-puncture layer 221 can be a PA material. The material of the first barrier layer 222 can be an aluminum foil film material, and the material of the second heat-sealing layer 23 can be a PE material, and the two adjacent layers are bonded with a two-component polyurethane adhesive and made through a dry composite process. Of course, the first heat-sealing layer 21 and the second heat-sealing layer 23 can also be made of PP or other suitable materials. PP is a polypropylene material, which is a thermoplastic synthetic resin with excellent performance. It is a colorless, translucent, thermoplastic, lightweight general-purpose plastic with chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties, and good high-wear-resistant processing performance.

[0046] As an optional embodiment, the thickness of the PE first heat-sealing layer 21 and the PE second heat-sealing layer 23 in the above type can be 40 μm, the thickness of the PA anti-puncture layer 221 can be 25 μm, and the thickness of the aluminum foil film first barrier layer 222 can be 7 μm.

[0047] Another type of material of the separator 2 is a plastic-plastic composite film that does not contain aluminum foil. Specifically, the material of the first heat-sealing layer 21 can be PE material, the material of the anti-puncture layer 221 can be PET material, the material of the first barrier layer 222 can be VMPET material, the material of the second heat-sealing layer 23 can be PE material, and the two adjacent layers are bonded with a two-component polyurethane adhesive and are made through a dry composite process.

[0048] Among them, PET plastic is the abbreviation of Polyethylene terephthalate, that is, polyethylene terephthalate plastics, mainly including polyethylene terephthalate PET and polybutylene terephthalate PBT. Polyethylene terephthalate is also commonly known as polyester resin. In recent years, due to the excellent performance, low cost and high price-performance ratio of PET, it has been widely used in the fields of electronic appliances, machinery, automotive parts, etc.

[0049] As an optional embodiment, the material of the first barrier layer 222 may also be EVOH material. EVOH is ethylene-vinyl alcohol copolymer, which combines the processability of ethylene polymer and the barrier effect of vinyl alcohol polymer. Ethylene-vinyl alcohol copolymer not only exhibits excellent processability, but also exhibits excellent blocking effect on gas, odor, fragrance, solvent, etc.

[0050] As an optional embodiment, the thickness of the PE first heat-sealing layer 21 and the PE second heat-sealing layer 23 in the above another type may be 40 μm, the thickness of the PET anti-puncture layer 221 may be 12 μm, and the thickness of the VMPET first barrier layer 222 may be 12 μm.

[0051] In addition, if Figure 5 As shown, a groove 31 is provided on the outer core material 3, and a getter 4 is arranged in the groove 31. The groove 31 mainly serves as an installation, and the getter 4 is mainly used to absorb oxygen and water vapor in the air. The groove 31 is arranged on the outer core material 3, which is more reasonable. When the air in the external environment penetrates into the independent chamber on the outside, the getter 4 located on the outer core material 3 is convenient for absorbing the oxygen and water vapor in the air that penetrates into the corresponding independent chamber, reducing the content of oxygen and water vapor in the air in the independent chamber, thereby protecting the adjacent independent chamber. Specifically, the getter 4 can be CaO and barium-lithium alloy and mixture, wherein CaO is mainly used to absorb water vapor and CO 2 , barium-lithium alloy is mainly used to absorb oxygen.

[0052] Specifically, Figure 5As shown, the groove 31 is provided on the side of the corresponding outer core material 3 away from the adjacent core material 3. That is to say, the groove 31 is provided on the side wall of the outer core material 3 close to the external environment, so that after the external air penetrates through the packaging bag body 1, the getter 4 in the groove 31 can absorb the oxygen and water vapor in the air in time, thereby preventing the further penetration of the air, and realizing the protection of the internal core material 3 and the independent chamber.

[0053] It should be noted that when making a multi-chamber vacuum insulation panel, the core material 3 of the original single-chamber single material can be split into multiple thinner core materials 3, and the multiple thinner core materials 3 can be loaded into multiple independent chambers and placed in a vacuum equipment for vacuum packaging, so that a multi-chamber vacuum insulation panel can be made, each independent chamber is an independent vacuum space, and adjacent independent chambers form a back-to-back structure, supporting and protecting each other.

[0054] It should be noted that when the vacuum insulation panel made of a packaging bag body 1 with one independent chamber, a packaging bag body 1 with two independent chambers, and a packaging bag body 1 with three independent chambers is placed in an air environment, the vacuum insulation panel is wrapped by the packaging bag body 1 on all sides, and there is a pressure difference of one standard atmospheric pressure between the inside and the outside of the vacuum insulation panel. Even if the packaging bag body 1 is made of high-barrier material, a small amount of gas molecules will still penetrate the packaging bag body 1 and infiltrate into the interior of the vacuum insulation panel.

[0055] The experiment used vacuum insulation panels made of the same material and the same process and placed them in the air. Because the barrier properties of the packaging bag body 1 are consistent, the pressure difference between the inside and outside is consistent, and the permeation rate of the gas penetrating the packaging bag body 1 is also consistent. Therefore, the pressure increase value in one independent chamber of the vacuum insulation panel made of the packaging bag body 1 with one independent chamber, the pressure increase value in two independent chambers of the vacuum insulation panel made of the packaging bag body 1 with two independent chambers, and the pressure increase value in the independent chambers on both sides of the vacuum insulation panel made of the packaging bag body 1 with three independent chambers are consistent. However, the difference is that in the vacuum insulation panel made of the packaging bag body 1 with three independent chambers, the larger area of ​​the partition 2 in the middle independent chamber is not directly in contact with the air, but is in contact with the two adjacent independent chambers. The pressure difference between the inside and the outside is much lower than one atmosphere. Therefore, the gas that penetrates into the middle independent chamber through the partition 2 will be very small, and the air pressure increase rate of the middle independent chamber is also very slow, so that the thermal conductivity of the independent chamber in the middle of the vacuum insulation panel will be maintained at an extremely low level for a longer time, ensuring the overall thermal insulation performance of the vacuum insulation panel and extending the service life of the vacuum insulation panel. This experiment can be extended to multiple independent chambers.
