Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is applied to a building member or a wrapping material by being wound, affixed, or applied by hand interposed between plates or sheets to provide heat insulation on the surface or inside thereof. The present invention relates to a sheet-like heat insulating material capable of improving the heat insulating property thereof, and a heat insulating member obtained by applying such a heat insulating material.

[0002]

2. Description of the Related Art The purpose of buildings is to protect and protect residents from the outside environment.
It has been used to block the wind and provide some heat insulation. However, recently, the number of dwellings that operate air conditioners throughout the year has been increasing, and energy efficiency has been further improved. For this reason, the inside of the house wall is filled with heat insulating material, and measures have been taken to prevent the room from excessively heating and cooling. Not taken, and because Japan is in a relatively warm climate zone, openings are often larger than in major European and American countries with low winter temperatures.

Of the materials constituting the opening member, glass is a relatively poor conductor of heat, but most of the window frame that surrounds and supports the panel body and the glass is made of aluminum. (= Thermal conductivity), there is a problem in energy efficiency, and of course, there is an advantage, but because it is a good conductor of heat, it transmits low temperatures outdoors in winter etc. Condensation on the inner surface,
In severe cases, water droplets may run down. Therefore, there is a method of dividing the material made of aluminum or the like and thermally insulating the space with plastic or the like, or suppressing the heat conduction by using double or triple windows. According to the latter method, there is a disadvantage that the thickness occupied by a thermally conductive metal such as aluminum among building members increases, and the disadvantage of using a material twice or three times is inevitable. .

[0004] In addition to the above building components, heat insulation is also important for packaging materials. For example, noodles that have been reduced in water content, such as fried in oil, and have improved shelf life are stored in containers along with condiments and seasonings, sold by the buyer, opened by the buyer, poured into boiling water, and eaten instantly. Noodles are sold in large quantities because they are easy to use. In addition to instant noodles,
Many products can be eaten in the same way. In addition to the function of preserving the stored items during sale, these containers are required to keep the food warmed by pouring hot water and to have heat insulating properties so as not to be heated when touching the containers. The purpose is to prevent burns and prevent the container from being knocked down when touched. In the past, many containers of this type were made of polystyrene resin foam in the shape of a container.Recently, however, paper has been wound into a bowl-shaped or cup-shaped container, and the outside has a bulky paper. It is often used for the purpose by covering it with folded paper with folds and folds. However, in the former, the strength of the container is weak, and in the latter, the bulky paper is soft when held in the hand, there is anxiety when holding it, and the folded paper with the folds is when held in the hand. There is a drawback that the friction force is small and it is difficult to hold. Alternatively, a heating vessel that generates heat when it comes into contact with moisture, such as quicklime and water, is bundled with the food to be warmed, and when needed, the quicklime is brought into contact with water to heat the food. It is applied to lunch boxes sold at stations and sake. Even in a bag-shaped heat pack (with a heating agent between two bags) for warming retort food outdoors on the same principle,
Insulation is necessary for heat retention and to prevent danger when touching with hands, but these are premised on leaving them to stand during heating and because they are covered with paperboard or paperboard to some extent, It is hot and has a hot disadvantage if touched carelessly during heating.

[0005] In addition, beverages and the like filled and sold in containers such as metal cans, glass bottles, and plastic bottles are usually warmed or cooled conventionally.
Once removed from a warmer, refrigerator, vending machine, etc., since the container does not have heat insulation function, the hot one cools down, the cold one becomes slim, and there is a drawback that dew drops due to condensation. are doing. This is because these cans and bottles are thin and there has been no effective means for imparting heat insulation.

[0006]

Therefore, in the present invention, for example, the space between the front and back of a thermally conductive building member made of aluminum or the like is blocked by plastic or the like, or the building member is used in a double or triple manner. Without reducing the conduction of heat, thus reducing the strength of building components,
It is an object to cut off heat conduction as much as possible without causing a disadvantage that the thickness of a material increases. Also, in the present invention, the surface of the paper container is soft or difficult to hold due to the presence of folds, lack of heat insulation of the heating container to a certain extent made of paperboard or coated with paperboard, such as cans and bottles It is also an object of the present invention to eliminate disadvantages such as a lack of effective heat-insulating means in a container.

[0007]

In order to solve the problem, various heat insulating materials were examined. The double wall and the inside were filled with fine particles or fibers of aerogel, carbon black or the like, or a foamed sheet or the like. Surprisingly, it has been found that the vacuum heat insulation method can be realized by using a very thin sheet-like body without using a thick heat insulating material usually used in a refrigerator or the like. . In addition, by sealing and packaging the heat-insulating material, it is housed in a molded body, or by supporting it by laminating it with a sheet-like base material, so that it is easy to fix when applying the heat-insulating material, and In addition, the protection of the heat insulating material was also achieved, and it turned out that it has high practical value. Furthermore, when the heat-insulating material is sealed and packaged and the inside is decompressed or vacuumed, the heat-insulating performance may be reduced due to vacuum leakage. It has been found that the use of side-by-side heat-insulating packagings can reduce the effects of vacuum leakage, and can easily cope with the shape of the application surface and steps. The present invention has been made based on these matters.

The heat insulating material is disposed in the concave portion of the dish-shaped molded body, packed and fixed. The third invention relates to the heat insulating material according to the first or second invention, wherein two or more of the plate-shaped or block-shaped heat-insulated packaging bodies having a sealed packaging structure are provided. Things. The fourth invention is

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A heat insulating material and a heat insulating member according to the present invention will be described below with reference to the drawings. In the present invention, the shape of the heat insulating material 1 is roughly classified into those shown in FIG. 1 and those shown in FIG.

As shown in FIG. 1, in the heat insulating material of the present invention, a rectangular heat insulating package 3 in which a filler is hermetically sealed is disposed on a sheet-like base material 2. Substrate 2
They are laminated with an adhesive therebetween. The size of the heat-insulating package 3 should be adjusted to the site to which the heat-insulating package 3 is applied, and is usually in the range of several cm to several meters. The heat insulating package 3 is preferably in the form of a plate or a block (lump) because it is easy to use, though it depends on the site to which the package is applied. In the present invention, since the filler that produces heat insulation is hermetically sealed,
It is possible to prevent breakage or decrease in heat insulating property, it is easy to secure the adhesiveness between the sealed product and the supporting film or molded product, and furthermore, the heat insulating material 1 to the adherend There is an advantage that the adhesiveness can be sufficiently ensured by utilizing the packaged surface also in the case of applying. 1 to 6
In the above, the individual heat-insulating packages 3 are drawn so as to be arranged with a gap therebetween, but may be arranged without a gap, and may be arranged in any manner according to the shape and use of the application location. it can.

The one shown in FIG.
Six rectangular heat-insulated packages 3 in which a filler is hermetically packed are arranged vertically and horizontally, and each heat-insulated package 3 is a sheet-like base material 2.
And an adhesive layer or the like.
Although the size of each heat insulating package 3 is not particularly limited, it is smaller than the case shown in FIG. 1 and is 1/6 of the area of the portion to which the heat insulating material 1 is applied. In addition, the number of the heat insulation packaging bodies 3 arranged side by side can be determined arbitrarily. in this way,
In the case where a plurality of heat-insulating packages 3 are stacked side by side, and when the inside of the heat-insulating packages 3 is under reduced pressure or vacuum, even if external force or a sharp object is pressed to break the packages, the adjacent heat-insulating packages 3 Body 3 has the advantage that it is not affected. Even if the surface to which the heat insulating material 1 is applied has a step, the flatness of the sheet-like base material 2 after application is ensured by disposing the heat insulating wrapping body 3 having a different thickness according to the step. There are advantages that can be done.

FIG. 3 is a cross-sectional view showing an application example of the heat insulating material 1 described with reference to FIG. 1 or FIG. 2, in which a heat insulating package 3 is laminated on a sheet-like base material 2. Insulation material 1
3a, as shown in FIG. 3A, the heat insulating package 3 is placed on the adherend 4 so that the side of the heat-insulating package 3 faces downward, and the margins 2a and 2z at both ends of the sheet-like base material 2 are Of the adherend 4 from both sides. Sheet substrate 2
If it has shape-retaining properties, it can be fixed as it is, but it may be fixed by bonding the sheet-like substrate 2 and the adherend 4 with an adhesive. Further, in FIG. 3B, the sheet-like base material 2 of the heat insulating material 1 has been extended to a part of the back surface of the heat insulating package 3 in advance, and is rolled up. In this case, the adherend 4 and any part of the heat insulating material 1 may be bonded with an adhesive.

FIG. 4 relates to a heat insulating material 1 using a molded body 5 in place of the sheet-shaped base material 2. The molded body 5 has a plate-like shape except for the periphery and a plate-like shape around the periphery. By having the surrounding portion 5a which is in a vertical relationship with the portion, the portion has a dish-like shape (it may be more appropriate to call it a tray shape). The height of the surrounding portion 5a may be, for example, substantially equal to the thickness of the heat insulating package 3,
Other dimensions are possible. A rectangular heat-insulated package 3 that is hermetically packaged is arranged and packed in the recess of the molded body 5, and the heat-insulated package 3 is fixed to the molded body 5 by an adhesive or the like. is there. The one shown in FIG.
As shown in the above, it is possible to prevent breakage and insulation deterioration,
When the heat insulating material 1 is applied, there is an advantage that the adhesiveness can be sufficiently secured by using the packaged surface.

FIG. 5 shows that the molded body 5
Six hermetically sealed rectangular heat-insulating wrappers 3 are arranged and packed in a row and column, and each heat-insulating wrapper 3 is fixed to the molded body 5 via an adhesive or the like. . As in FIG. 2, the size of each heat insulating package 3 is not particularly limited, but is smaller than that shown in FIG. 4, and is １ ／ of the area of the portion to which the heat insulating material 1 is applied.
In addition, the number of the heat insulation packaging bodies 3 arranged side by side can be determined arbitrarily. By using a plurality of heat insulating packages 3, the same advantages as those described with reference to FIG. 2 can be obtained.

FIG. 6 shows an example in which the heat insulating material 1 described with reference to FIG. 4 or FIG. 5 is applied to the adherend 4, and in FIG. 5 shows an example in which the heat insulating material 1 bonded to 5 is placed on the adherend 4 and laminated by an adhesive layer or the like. In this case, the lower surface side of the heat insulating package and the upper surface of the adherend, and / or the vertical surrounding portion 5a of the molded body 5 and the adherend are bonded.

In FIG. 6B, the end of the molded body 5 is extended downward and has a bent portion which is bent inward at a right angle, so that there is a margin for the thickness of the adherend 4. The heat insulating material 1 to which the heat insulating package 3 is previously adhered to the molded body 5 is slid in the longitudinal direction of the adherend 4 (in the figure, from the near side to the far side, or in the opposite direction). Accordingly, the heat insulating material 1 is laminated on the adherend 4. According to this applicable law,
Fixing can be performed without necessarily using an adhesive. One side or two sides facing each other are removed from the enclosing portion 5a in order to perform the sliding.

In FIG. 6 (c), the end of the enclosing portion of the molded body 5 has a bent portion which is bent at a right angle toward the inside, but has a space between which only the heat insulating package 3 can enter. Since the adherend does not enter, the heat insulating material 1 is fixed to and adhered to the adherend 4 by bonding between the lower side of the bent portion and the adherend 4. By the way, FIG.
In (c), the heat insulating package 3 and the adherend are not in contact with each other except at both ends, and this is effective because the influence of the heat bridge of the packaging material itself of the heat insulating package 3 can be reduced. . In that sense, as illustrated in FIG. 6 (d), the case where the heat insulating package 3 and the adherend 4 are fixed in a state where they are not in contact with each other at all is further increased in the packaging material itself. The effect of the heat bridge can be minimized, which is effective. In the present invention, these are included in the range. Although not shown in FIG. 6D, a protrusion is provided between the bent portion and the protrusion by providing a protrusion directly above the adherend 4 and inside the molded body 5. It is good to fix with.

When storing the heat insulating material 1 in the molded body 5, the following structure and method can be adopted. FIG.
As shown in (a), after the depth of the concave portion of the molded body 5 is increased and the heat insulating package 3 is housed, the sheet-shaped or thin-plate-shaped lid 6 is covered, and the front end (the lower end in FIG. ), A bent portion 5b (facing in a direction parallel to the molded body 5) is formed, and the lid 6 can be fixed by the portion 5a.

The fixing of the lid 6 is performed by the above-mentioned bent portion 5.
Instead of b, a method may be used in which a groove 5c parallel to the molded body 5 is formed on the inner surface near the front end (lower end in the figure) of the enclosing portion, and the lid 6 is fixed using this groove 5c.

In order to store the heat insulating material 1 in the molded body 5, the heat insulating package 3 can be fixed at the time of molding. FIG.
As shown in (a), according to the method of covering the periphery of the heat insulating package 3 with the molded body 5, the heat insulating package 3 can be fixed by the molded body 5 without taking the special fixing means as described above. . Such a configuration can be achieved by setting a heat insulating package in a mold at the time of molding. Or,
As shown in FIG. 8B or 8C, it is also possible to insert and fix from one side of the molded body. These forms are manufactured in the same manner as shown in FIG.
Or, heat-insulating packaging 3 while resin immediately after molding is soft.
Can be done by placing In FIGS. 7 and 8, it is illustrated as if one heat insulating package 3 is used.
Two or more multiples can be used.

Incidentally, the heat insulating package 3 basically has a structure in which the filler 7 is sealed between two sheets 8 and 8 ', as shown in the cross-sectional view of FIG. Preferably, the sheets 8 and 8 ′ have gas barrier properties and the inside of the sealed structure is in a reduced pressure state or a vacuum state. Specifically, the filler 7 is sealed in a space formed by molding one of the sheets 8 or is sealed in a space formed by molding of both sheets 8 and 8 ′ (shown in the drawing). Zu.).

Accordingly, the heat-insulating package 3 has a collar 9 around the periphery of which a seal is formed. The brim 9 differs in the height direction of the brim depending on whether only one sheet 8 is formed or both sheets 8 and 8 ′ are formed. As shown in FIG. It may be located on the lower side (sometimes on the upper side) or in the middle of the height of the filler. In order to complete the sealing, the width of the collar 9 is required to some extent. However, the collar 9 hinders the filler 7 from arranging the heat-insulating packages 3 closely. For this reason, as shown in FIG. 10 (a), the brim portions of the heat-insulating packaging bodies 3 and 3 ′ are arranged side by side, or as shown in FIG. It is advisable to arrange the heat-insulated packages as closely as possible.

Alternatively, as shown in FIG. 10 (c), if every other unit is arranged upside down, it is possible to bring them closer to each other, and it is not always necessary to bend the brim at the overlapping position. In addition, as shown in FIG.
If every other empty space for one filler is formed in advance, the arrangement can be easily performed by arranging the respective convex portions in the corresponding concave portions. FIG. 6A to FIG.
In (d), it is better to bend the outer flanges at both ends when arranged.

As shown in FIG. 10 (d), the heat insulating package 3 may not be formed one by one, but may be formed by connecting two or more. In short,
Each of the fillers 7 is independent so long as the structure does not affect the location of the adjacent filler 7 even if vacuum leakage occurs at one filler 7. Such a thing can be seen as a sheet in which a sheet for hermetic packaging and a flexible sheet-like substrate for supporting each heat insulating package are integrated. Therefore, in the embodiment described with reference to FIGS. 1 to 8, as shown in FIG. 10D, as shown in FIG. It is also possible to use either one or both.)

The material constituting the filler 7 is various, and will be described in detail later. The material is a foamed sheet or a fibrous or particulate material. In the case of fibers or particles, there is a space between adjacent fibers or between adjacent particles, or in the case of a porous body, a minute space inside. have.
In the state of the heat insulating composite sheet 1, these voids may be filled with air at atmospheric pressure, in a reduced or vacuum state, or filled with a gas other than air. .

The sheets 8 and 8 'cover the outside of the filler 7 and hermetically seal and package the filler to protect the filler 7 and at least suppress or prevent the permeation of moisture. Is maintained in a vacuum to exhibit heat insulation. In order for the heat insulating material of the present invention to further exhibit heat insulating properties, the presence or absence of air may be present. However, in one embodiment, the heat conduction by air may be reduced or eliminated by setting a reduced pressure state or a vacuum state. Is preferable.

If it is not particularly necessary to maintain a reduced pressure or vacuum state, the package may be hermetically sealed using a flexible sheet that does not necessarily have a gas barrier property. Examples of such a flexible sheet include polyethylene resin, polypropylene resin, and polymethylpentene resin. , Polyvinyl chloride resin, polyvinylidene chloride resin, polyvinyl alcohol resin, vinyl chloride-vinyl acetate copolymer resin, ethylene-vinyl acetate copolymer resin, ethylene-vinyl alcohol copolymer resin, polyethylene terephthalate resin, polybutylene terephthalate resin, polyethylene Polyphthalate represented by naphthalate-isophthalate copolymer resin, phenol resin, polymethyl methacrylate resin, polyethyl methacrylate resin, polybutyl acrylate resin, nylon 6 or nylon 66, etc. Bromide resins, polyurethane resins, polyisocyanurate resins, cellulose triacetate resins, cellophane, a polystyrene resin, polycarbonate resin, polyarylate resin or sheet made of a synthetic resin such as a polyimide resin, can be used. Among them, polyethylene resin, polypropylene resin, phenol resin, polystyrene resin, polyvinyl chloride resin, polyurethane resin, or polyisocyanurate resin are suitable,
Polyethylene-based resins or polypropylene-based polyolefin-based resins are more preferable because harmful substances are less likely to be emitted at the time of disposal. Sheets made of these resins may be composed of two or more synthetic resin sheets of the same or different types, if necessary.
It may be used as a laminated sheet composed of multiple layers.

These flexible sheets are generally uniaxially or biaxially stretched. If necessary, a discharge treatment such as a corona discharge treatment or a low-temperature plasma treatment, a silane coupling agent application, a sol-gel agent application, or a surface treatment such as a sandblast treatment is performed to improve adhesiveness and gas barrier properties. Good.

The flexible sheet may be used as a gas barrier sheet by laminating a layer having a low moisture permeability or a gas barrier property, if necessary. In particular,
When the inside of the heat insulating package 3 is decompressed or evacuated,
Always use gas barrier sheets. The gas barrier sheet is roughly classified into a so-called vapor-deposited film in which a thin film is formed by vapor deposition or chemical vapor deposition, or a so-called “coat film” by painting.

The deposited film is a transparent deposited film on which alumina or silica is deposited, or a non-transparent deposited film on which aluminum or the like is deposited. The coated film is a polyvinylidene chloride resin coated with a polyvinylidene chloride resin paint. There are coated films and the like.

The deposited film may be a mixture of metal oxides having different oxidation numbers such as silicon monoxide and silicon dioxide, a mixture of a silicon compound and aluminum oxide, or an inorganic oxide. May be bonded to an organic group mainly composed of As a method for forming a thin film, for example, a physical vapor deposition method such as a vacuum deposition method such as an ion beam method or an electron beam method, or a sputtering method, or a plasma chemical vapor deposition method, a thermochemical vapor deposition method, or A chemical vapor deposition method such as a photochemical vapor deposition method can be used, and the thickness of the thin film is preferably 50 to 3000.
、, and more preferably 100 to 1000Å.
If it is less than 50 °, there is almost no effect of suppressing gas permeation, and if it exceeds 3000 °, cracks may occur in the thin film and gas permeability may be reduced, and the material cost is relatively high.

As the flexible sheet, those made of the above-mentioned plastics are easy to use. In addition, various kinds of paper, metal foil, metal sheet or metal plate as described below can be used. , Wood veneer,
Alternatively, a ceramic sheet or the like can be used according to the application. In addition, flexible in the word of the flexible sheet, at the time of production or handling, at least, when wound around a roll of about several tens of cm in diameter, and when wound around the side of a cylinder or the side of a prism, This means that the shape can be easily deformed following the shape.

The following are typical examples of various papers. That is, tissue paper, kraft paper,
Titanium paper or a resin-impregnated paper which has been impregnated with a resin in advance for the purpose of strengthening between papers can also be used. In addition, linter paper, paperboard, or a group of fabrics often used in the field of building materials such as synthetic resin wallpaper fabrics with a synthetic resin layer such as polyolefin resin or polyvinyl chloride resin on the surface, or coatings Paper, art paper, parchment paper, glassine paper,
Parchment paper, paraffin paper, Japanese paper, or the like.

Although distinguished from these papers, woven or nonwoven fabrics of various fibers having the following appearance and properties similar to paper can also be used as the flexible sheet. It is a woven or nonwoven fabric of an inorganic fiber such as glass fiber, asbestos fiber, potassium titanate fiber, alumina fiber, silica fiber, or carbon fiber, or a synthetic fiber such as polyester fiber or vinylon fiber.

As the metal foil, metal sheet or metal plate, aluminum, iron, stainless steel, copper, brass, tin,
Gold, silver, platinum and the like. It is often used after plating. The gas barrier layer has a difference in thermal conductivity depending on the constituent materials, and when the aluminum thin film which is a typical gas barrier layer is used, particularly when the aluminum thin film is used on the inner side, the thermal conductivity of aluminum itself is very high. Therefore, a heat bridge may occur via the gas barrier sheet, and the heat insulation performance may decrease.

In order to manufacture a heat insulating package by sealing and packaging with a flexible sheet, besides stacking and sealing two sheets, a method of folding one sheet and sealing three sides other than the fold line, or a tube The two sides may be blown using a sheet made in a shape, a bag of aluminum foil with one open may be used, and the opening may be sealed.
The filler 7 is placed in the center of the sheets, the periphery of the sheet is lifted to form a drawstring, and the opening is sealed. Either way, the entire periphery of the filler 7 is covered with a flexible sheet. As long as it is sealed, it is possible to produce the heat insulating package of the present invention in any form,
It is preferable to overlap two sheets and seal the periphery, because the influence of the heat bridge is small.

When two sheets are overlapped and sealed, use two sheets which are exactly the same, use sheets of the same material but different thicknesses, or use sheets of different materials. Can be.

In the heat insulating material 1 of the present invention, the filler 7 is filled in the hermetically sealed package made of the flexible sheet as described above. Examples of the material of the filler 7 include a synthetic resin foam sheet, fiber (including hollow fiber and felt), paper, nonwoven fabric, ceramic sheet, fiber sheet, fine particles, and hollow particles.

As the foamed sheet, those made of the following resins can be used. That is, polyethylene resin,
Polypropylene resin, polymethylpentene resin, polyvinyl chloride resin, polyvinylidene chloride resin, polyvinyl alcohol resin, vinyl chloride-vinyl acetate copolymer resin, ethylene-vinyl acetate copolymer resin, ethylene-vinyl alcohol copolymer resin, polyethylene terephthalate resin ,
Polybutylene terephthalate resin, polyethylene naphthalate-isophthalate copolymer resin, phenol resin,
Polymethyl methacrylate resin, polyethyl methacrylate resin, polybutyl acrylate resin, polyamide resin represented by nylon 6 or nylon 66, polyurethane resin, polyisocyanurate resin, cellulose triacetate resin, cellophane, polystyrene resin, polycarbonate Resin, polyarylate resin, polyimide resin, or the like.

As the foamed sheet, among others, polyethylene resin, polypropylene resin, phenol resin, polystyrene resin, polyvinyl chloride resin, polyurethane resin,
Alternatively, a polyisocyanurate resin is suitable, and a polyolefin-based resin such as a polyethylene resin or a polypropylene resin is more preferable, because harmful substances are less likely to be generated at the time of disposal.

As the foaming state of the foamed sheet, two types of open cells and closed cells are known. In the present invention, a reduced pressure state or a vacuum state is realized by evacuation of a vacuum pump or the like so as to achieve a heat insulating property. In order to improve the value, it is desirable to use an open cell.

The foamed sheet includes a hard sheet and a soft sheet. The resin constituting the foamed sheet is a thermosetting resin, and among the foamed cells having closed cells, an epoxy resin, a urea resin, or a foamed sheet composed of a phenol resin, or a thermoplastic resin, but composed of a cellulose acetate resin The foam sheet is hard, and the foam sheet made of polyethylene resin, polystyrene resin, polyvinyl chloride resin, polyvinyl alcohol resin, polyurethane resin, isocyanurate or silicon resin is either hard or soft.

For the heat insulating material 1 of the present invention, when the heat insulating material is compressed by a difference from the atmospheric pressure and the heat insulating performance is not extremely reduced, when the heat insulating material 1 is hermetically covered with a gas barrier sheet and brought into a reduced pressure state or a vacuum state, it is hardened. Any flexible foam sheet can be used. However, generally speaking, the rigid foamed sheet has better heat insulation performance, and the soft foamed sheet is softer in material, so that it is superior in moldability and followability to the shape to be stuck. It has high properties and also has sufficient heat insulation performance close to a rigid foam sheet. In addition, a soft foamed sheet may be compressed when the pressure is reduced or reduced.

Soft foamed sheets can be manufactured by a method such as melting and extruding a resin composition containing a foaming agent. Hard foamed sheets are usually very thick, Foaming in the mold with the gap of
2 by cutting or slicing a thick foam sheet
A thin sheet having a predetermined thickness of about mm or less can be obtained.

Other conditions for the foam sheet include thickness, density, and the like. In the case of heat insulation of walls of buildings and houses, it is used with a thickness of several cm, but in the present invention, application to the surface of building members and packaging materials is assumed, so application becomes difficult if it is too thick Therefore, the thickness of the foam sheet is 1
It is preferably about 0 μm to 2 mm. The range of the density of the foamed sheet is 0.00
5 to 1 g / cm ³ , more preferably 0.01 to 0.2 g
/ Cm ³ . The closed-cell foam sheet is not limited to the open-cell foam sheet because the heat insulating property of the closed-cell foam sheet can be enhanced when the pressure is reduced or reduced.

The material of the filler 7 includes fibers (including hollow fibers). The fibers may be either long fibers or short fibers, but short fibers are more preferable. The fiber may also be a fiber sheet made of a sheet of glass fiber, glass wool, rock fiber, rock wool, alumina fiber, felt, nonwoven fabric, ultra-low density paper, or the like made by intertwining the fibers. A laminate of two or more layers, such as felts, nonwoven fabrics, or ultra-low-density papers, or two or more different laminates such as felt, nonwoven fabrics, and ultra-low-density papers may be used.

Originally, felt was made by collecting animal hair, entangled by pressurizing while heating and humidifying, and forming a sheet. However, as a raw material, synthetic fibers, rock wool, carbon Fibers are also used. Non-woven fabric
Fibers (natural fibers are also treated, but usually synthetic fibers) are directly spun without mechanical spinning by mechanical, thermal, or chemical means into sheets. The paper is manufactured by entanglement of plant fibers and other fibers and agglutination (as defined by JIS).

As is clear from these definitions,
Felts, nonwovens, and paper, while seemingly different from each other in typical products, are essentially indistinguishable from each other.However, ordinary paper has a higher density than others. Are different in that The density of the ultra-low density paper referred to here is 0.1 g / cm ³ to
3 g / cm ³ is common, for example, 0.2 g / cm ³
It is about.

In the case of including felt, nonwoven fabric and cloth, the density is 0.005 g / cm ^{3 to 3} g / cm ³ , and preferably 0.005 g / cm ^{3 to 1} g / cm ³ .
Considering ease of handling, 0.02 g / cm ^{3 to} 1 g /
cm ³ , more preferably 0.02 g / cm ^{3 to} 0.8
g / cm ³ . If it is less than the lower limit, the strength is low,
The risk of damage during handling increases, and if it exceeds the upper limit, the heat insulating properties become insufficient.

Since the fiber material itself is bulky,
It is common to refer to the so-called "bulk density", but in the above-mentioned paper, felt, non-woven fabric, or cloth, etc., pressure and tension are used to produce dense materials. Even when used in combination with other materials, it can be seen that the density is in the above-mentioned range because the material is compressed during filling or molding.

Among the fibers, there are hollow fibers hollowed out during the production thereof. Hollow fibers are less likely to be crushed than inorganic or organic hollow particles. Therefore, a heat insulating sheet obtained by using hollow fibers has the advantage of high heat insulation and less damage by compression.

Examples of hollow fibers are polypropylene,
After melting crystalline polymers such as polyethylene and poly (4-methylpentene-1), they are taken at a high draft ratio to form a structure in which lamellar crystals are oriented and laminated in the taking-off direction. After forming microfibrils between lamellas in the cold stretching process to generate voids,
The microfibrils expand by plastic deformation under high temperature, and those obtained by expanding the voids into slit-shaped holes, or by using the copper ammonia method, the undiluted solution is supplied from the outside of the double-tube structure spout, Some of them are obtained by supplying a hollow agent, which is a non-coagulable fluid, to the inside, extruding, stretching and passing through a coagulation bath, a regeneration bath or the like.

The diameter of the hollow fiber is 50 μm to 50 μm.
Since it is about 0 μm and the length is preferably about 1 mm to 15 mm, it is cut and used as necessary. In addition, the cloth is preferably a fiber using a heat insulating fiber such as a hollow fiber as a fiber, but is not necessarily a heat insulating fiber such as a hollow fiber. If it is a cloth, it can be used.

The following are examples of the particles of the filler 7 to be filled. Examples of the fine particles include titanium dioxide, silica, alumina, pearlite, and calcium silicate. Porous silica is used as the porous fine particles,
There are activated carbon, diatomaceous earth, activated clay, and molecular sieve. Examples of the hollow particles include organic particles made of an acrylic resin such as acryl and acrylonitrile and synthetic resins such as polystyrene resin, and inorganic particles made mainly of silica and alumina. As a natural product,
Something like a volcanic shirasu balloon can also be used. Moreover, hydrophilic or hydrophobic hollow particles can also be used. These have a particle size of about 0.3 to 300 μm. When hollow particles are used, even if the pressure is reduced or evacuated, air in the hollow portions remains, but it is considered that the air between the particles is exhausted to exhibit heat insulation performance.

Examples of the ultrafine particles having a particle size of 100 nm or less include titanium dioxide, silica, aluminum and the like.
In particular, carbon black and Ketjen black have a small particle size and a dark color, so that radiant heat can be suppressed, and they are more effective than ultrafine particles.

As the porous body among the materials of the filler 7,
There are the following: Examples of the porous body include calcium silicate and activated carbon. Since the porous body has small voids on the nanometer (nm) level in its structure, the porous body has good heat insulating properties. Moreover, since it is a molded body, it is easy to manufacture and handle, and the risk of breakage is very small. What is called an aerogel is also included in this range. Aerogels include silica aerogels, carbon aerogels, and resin aerogels, which have almost ideally several tens of nanometer voids in a unit volume, and the particles that serve as the skeleton of the structure are also in point contact. High effect. Also,
For example, the heat insulation performance can be improved by doping carbon black into silica airgel to absorb radiant heat. Carbon aerogel has been improved in view of the brittleness of silica aerogel, and is also suitable as a core material (filler) for vacuum insulation.

[0057] These porous bodies are formed by particles serving as a skeleton of the structure.
The size of the element is as small as 1 nm to 100 nm,
In addition to providing thermal properties, the particles are close to point contact
Contact makes it difficult for heat to be transmitted,
Since the gap is small, the effect of convection can be reduced. these
Use the porous body as it is, or mix it with fiber, etc.
May be used as a filler to produce a porous body,
The density of the filler made of the above various porous materials is
0.005 to 1 g / cm ^ThreeIt is preferred that What
Regarding the material particles or porous material,
It is common to say so-called "bulk density",
When using una material alone or in combination with other materials
Is also compressed during filling and molding,
May be considered to be within the above-mentioned density range.

The above-mentioned foamed sheet, hollow fiber or sheet thereof, various kinds of particles, or porous body can be arbitrarily used in combination of two or more kinds. Among them, various particles or a porous body mixed with fibers in the sense of reinforcement, preferably molded and used, and the fiber is 1 to 10 parts by weight with respect to 100 parts by weight of various particles.
It is advisable to mix and use about 00 parts by weight. Regardless of which material is used as the filler, the gap is in the range of 1 nm to 1 mm.

In the heat insulating material 1 according to the present invention, even when the inside of the hermetically sealed space having the filler 7 is at atmospheric pressure, the heat insulating property can be exerted by the action of the filler 7, but the air ( The meaning of normal atmosphere) is freon gas, carbon dioxide gas,
Substitution with a low thermal conductivity gas such as cyclopentane provides better heat insulation than when air is contained inside.

Further, by setting the inside to a reduced pressure state or a vacuum state, higher heat insulating properties can be exhibited. As for the degree of the reduced pressure state or the vacuum state, it is preferable that the lower the lower the lower the probability of collision between gas molecules. It is assumed that 1 Torr (= 1 mm
Hg), the mean free path of the air is 50
Since it is about μm, if the size of the space in which air molecules can freely move around is surely smaller than 50 μm due to the presence of the filler, heat conduction due to collision of air molecules hardly occurs.

It is to be noted that, depending on various dimensions of the material serving as the filler, if the air is exhausted to an air pressure of 10 Torr or less, a practically satisfactory heat insulating property can be obtained. If the degree of vacuum is further increased, the heat insulating property is enhanced, and as a lower limit, 10 ^-6 T
Orr is preferable because higher heat insulating properties are obtained, but practically, a predetermined degree of vacuum can be reached in a short time, and a lower limit of 10 ⁻³ Torr can be prevented during storage. Is more preferable. Also, once the filler 7 is
The inside of the air permeable bag may be sealed with a gas barrier sheet to evacuate the inside.

Further, a substance serving as a getter, for example, calcium hydroxide, activated carbon, activated carbon fiber, silica gel, zeolite, molecular sieve, or the like may be coexisted with the filler 6 in a sealed package, or the getter itself may be used as the filler. To remove moisture, or to maintain the vacuum state by mixing the getter in the packaging material so that the packaging material acts as a getter. The degree of vacuum may be maintained by adsorbing a gas (for example, in the case of a foamed polyurethane resin, carbon dioxide gas generated by reacting with moisture) generated due to a temporal change of the internal filler.

It is to be noted that packing the filler 7 in this way to suppress the collision of air molecules and obtain heat insulation itself is as follows.
It is known in the field of vacuum insulation, and produces an effect at a relatively low degree of vacuum.In this case, the inside of the double wall is filled with a filler and the thickness becomes, for example, several tens of mm. Only used, as in the present invention, sealed with a flexible sheet, preferably a gas barrier sheet,
Conventionally, there has been no example of a heat insulating sheet to be applied to a building member or a packaging material by being wound, attached, or interposed therebetween for imparting heat insulating property.

In the present invention, the flexible sheet-like base material 2 supporting the heat-insulating package 3
Filler 7 can be used as a sheet for hermetic packaging. It is not always necessary to use a gas barrier sheet, but since moisture resistance may be desired, it is usually preferable to use a sheet made of the synthetic resin described above as a flexible sheet, but a gas barrier sheet may also be used if necessary. I do. The sheet-shaped substrate 2 may be transparent or opaque, but if it is necessary to cover the heat insulating package, opaque is preferred.

In the present invention, as the molded body 5 having a concave portion for filling the heat insulating package 3, one made of various materials and manufacturing methods can be used. As the material, general-purpose materials such as ABS resin, AES resin, polyolefin-based resin, polyvinyl chloride resin, and polycarbonate resin can be used. In addition to these, wood powder-containing resin (for example, ABS resin) and the like can also be used. Can be used.

In particular, a molded article molded using a resin containing wood powder can produce a marble pattern with the mixed wood powder. Wood powder can be blended in a resin composition used for molding in an amount of 20 to 70%.

To produce the molded body 5, extrusion molding,
In addition to molding methods from raw resin such as injection molding, lamination, welding, vacuum and / or
Alternatively, it is possible to use a method such as pressure molding or the like to cut a completed rod-shaped or lump-shaped object. When the thickness of the molded body is thin and is about 1 mm or less, a solid form is preferable, and when a thickness of 2 mm or more is allowed, foam molding can also be used.

In order to improve the adhesive strength with the heat insulating package 3,
Alternatively, when the molded body 5 is involved in the adhesion between the heat insulating material 1 and the adherend 4, the bonding surface of the molded body 5 is pre-treated by a primer treatment, an application of an adhesive, a corona discharge treatment, or the like, It is preferable to improve the adhesiveness.

Since the heat insulating material 1 of the present invention is laminated on or near the surface of a building member or a packaging material, it is exposed to the outermost layer or can be seen from the outside. May be applied. Here, “on the observation surface side” includes a case where the back surface of the transparent film is decorated and observed from the front surface side.

There are various ways of applying makeup, but coloring, printing, embossing, or wiping painting are typical, and one or more of these may be arbitrarily selected and combined. It is only necessary that makeup be applied. The makeup is applied directly to the surface of the sheet-like base material or the molded body, which is opposite to the side on which the heat-insulating packaging body 3 is laminated, or the makeup is provided with a makeup such as an airbrush. Makeup can be applied by attaching a sheet. Although the base material of the decorative sheet can be arbitrarily selected, it is preferable to use an acrylic resin sheet having high weather resistance or a fluororesin sheet resistant to contamination depending on the use.

The heat insulating material 1 of the present invention can be used as a heat insulating member by winding or pasting it on various building members or packaging materials. FIG. 11 shows a plate-like body 12 on the front and back of a frame 11.
This is an example in which heat insulating materials 1 and 1 'are laminated on both surfaces of a building member on a thermally conductive panel 10 in which heat insulating materials 12 and 12' are laminated on the front and back to provide heat insulation. The structure as shown in FIG. 11 is applied to a door, a wall surface, a ceiling surface, a floor surface, or the like, or
It can be used for cabinets and the like that require heat insulation, and can provide heat insulation to a certain extent.

The lamination or fixing of the panel 10 and the heat insulating materials 1 and 1 ′ is carried out by using an adhesive or an adhesive, or by heat sealing, or by using an adhesive tape, a double-sided tape, a nail, a screw, a wire or the like. You may. Alternatively, panel 10
The heat insulating material 1 is slid from the side, fixed from the front, and fixed with the claws, or a chuck sheet (eg, Sumitomo 3M, product name: "Dual Lock"). "Fastener" or "mating surface fastener"). These lamination or fixing methods are common when the heat insulating material 1 is applied to an object to which heat insulation is to be imparted, and may be selected and used according to the application. Screw stop,
The above-mentioned slide or fitting, or fixation with the chuck sheet is used to separate, collect, reuse (reuse), or recycle (collect and reuse as resources) what should be discarded after stopping use as a product. Are suitable. Deformed two-color molding, such as using a claw portion as a material such as rubber or silicone resin, can also be used. The claw of rubber or silicone resin is deformed when the heat insulating material 1 is attached without causing deterioration due to bending, so mounting is difficult. It will be easier. In general, the adhesive is often attached, so it is preferable to apply an adhesive to the heat insulating material 1 in advance, and the same applies to another type of building member described with reference to FIG.

FIG. 12 shows an example in which the heat insulating material 1 of the present invention is laminated on an object having a long length. One side surface of a hollow prism made of aluminum or the like extends along the length direction and has a fixed portion near the center. It is an example of the heat insulating member which laminated | stacked the heat insulating material 1 of this invention on the surface of the heat-conductive extruded shape material 13 of the shape removed in width. The structure as shown in FIG.
Although it depends on the use of No. 3, it can be used as a frame of a door, a frame for attaching a door, such as a pillar, a skirting board, a Kamoi, a sill, a sliding door or a hinged door. The shape of the extrusion 13 in FIG. 12 is an example, and other shapes may be used. The lamination or fixing may be performed via an adhesive or an adhesive.
Other methods, such as those described with reference to FIG.

In addition to these, wrap around the side of an instant food container that is poured with boiling water, such as a cup of instant noodles.
Alternatively, it can be used as a heat insulating material for a packaging material by pasting around the heating container or the outer surface of the lid as described above, pasting outside the heat pack, or wrapping around or pasting around a can or bottle. . Depending on the shape of the adherend,
It is preferable that the shape of the heat insulating package is not a flat plate but a side surface of a column or a cone.

Regardless of the form in which the heat insulating material 1 of the present invention is applied, the heat insulating package 3 applied on the adherend 4
Since the surface is covered with a sheet-like substrate or a molded body, it is possible to alleviate the impact due to an external force, and it is difficult to break or increase the resistance to sharp objects.

Two box-shaped molded bodies each having a width of 208 mm and a height of 1.6 mm were prepared, and a decorative sheet mainly composed of 100 μm-thick acrylic resin was bonded to the outside of the bottom surface with an adhesive.

The heat insulating package was prepared by using a carbon airgel as a filler and a polyethylene film on which aluminum was deposited as a packaging material, and vacuum-packing it at a degree of vacuum of 0.1 Torr. The obtained heat-insulated package (= vacuum heat-insulated package) had a length of 15 mm × width; 100 mm × total thickness; 1.5 mm, a seal width of 3 mm, and a brim width of 5 mm. Two of the obtained vacuum heat-insulated packages were placed in each of the above boxes and fixed with double-sided tape to obtain a heat insulating material. When putting the vacuum insulation package in the box,
In one box, (A) the film seal portions on the four sides around the vacuum heat insulating package were not folded only on one side, and the vacuum heat insulating packages were stacked on each other at the unfolded portions. In the other box, (B) vacuum A method was adopted in which the film seal portions on the four sides around the heat-insulating package were all folded back and then arranged.

As the heat-insulating package, the same vacuum heat-insulating package as that obtained in Example 1 was used and fixed to the inside bottom surface of the above box with double-sided tape. For comparison, a foamed plate made of a polypropylene resin having an expansion ratio of 8 times and a thickness of 1.5 mm was fixed to the bottom surface inside the box with a double-sided tape. Thereafter, when the evaluation was performed in the same manner as in Example 1, the surface temperature of the heat insulating material when the vacuum heat insulating package was used was 11.5 ° C. Was 9.8 ° C.

After fixing on the same aluminum plate as in Example 1 with the side of 0 mm × 60 mm facing down, the above-mentioned heat-insulating material sheet was placed on the upper surface of one of the hollow square pillars with the vacuum heat-insulating package side down. And fixed with double-sided tape.
Nothing was stuck on the other hollow square pillar.

After that, when the evaluation was performed in the same manner as in Example 1, the surface temperature of the vacuum heat insulating material when the vacuum heat insulating material was used was 11 ° C. The temperature was 1 ° C.
