Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to a building component, and provides a heat insulating property to the surface of the component, thereby improving the heat insulating property of the building component. And a heat insulating building member to which the heat insulating composite sheet for building material is applied.

[0002]

BACKGROUND OF THE INVENTION The original purpose of a building is to shield and protect occupants from the outside environment, to prevent wind and rain and to mitigate extreme changes in temperature. For this reason, as the various building materials constituting the building, materials that do not leak, block the wind, and have a certain degree of heat insulating properties have been used since ancient times. However, recently, not only seasonal heating and cooling, but also homes equipped with equipment that maintains a comfortable living environment throughout the year and 24 hours are increasing, and energy consumption is increasing. Energy efficiency has been improved.

For this reason, the space between the outer wall and the inner wall of the house is filled with a heat insulating material, and measures are taken to prevent the room from being excessively heated or cooled.
Glass doors and windows are not as well insulated as walls. Especially in Japan, except for the northern part of the Tohoku region, there is a relatively warm climate zone, so there is a traditional method of providing sufficient sunlight throughout the year and having a structure that is advantageous for ventilation in summer. However, it is common to have more openings than in major European and American countries with low winter temperatures.

[0004] Glass used for door panels, glass sliding doors, windows, and the like, which are opening members, is a relatively poor conductor of heat. However, some window frames that support the panel body and glass are made of iron. Except for those made of aluminum or PVC, most are made of aluminum and are good conductors of heat (= thermal conductivity). Thermally conductive building materials such as aluminum are resistant to rust,
It has advantages such as light weight, easy to use and use, cleanliness, and no need for painting.On the other hand, since it is a good conductor of heat, it communicates low outdoor temperatures in winter and so on, Surface becomes low temperature. For this reason, the moisture in the indoor air condenses on the surface of the aluminum building material and, in extreme cases, adheres as water droplets and eventually runs down. If you change aluminum to iron,
Although it is difficult to conduct heat, it is not so bad as a poor conductor of heat, and it can be said that there is essentially no difference.

Therefore, there is a method of blocking the front and back of the building material with plastic or the like, or using double or triple to suppress heat conduction. However, according to the former method, the strength of the building material is reduced. According to the latter method, the thickness of a heat conductive metal such as aluminum among the building materials is disadvantageously increased, and the material is doubled or three times larger.
The disadvantage of using twice is inevitable.

[0006]

Therefore, in the present invention, the space between the front and back of a thermally conductive building material made of aluminum or the like is blocked by plastic or the like, or the building material is used in a double or triple manner. Without suppressing the conduction of heat
Accordingly, it is an object of the present invention to cut off heat conduction as much as possible without reducing the strength of building materials or increasing the thickness of the materials.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the structure of a heat insulating composite sheet for a building member and a heat insulating building member of the present invention will be described with reference to the drawings. As shown in FIG. 1 (a), a heat insulating composite sheet 1 for a building component of the present invention is preferably formed by laminating a low moisture permeable sheet 3 on an upper surface of a heat insulating sheet 2 having irregularities on the upper surface. 1 or a space 4 containing air therein, or as shown in FIG. 1 (b), the heat-insulating sheet 2 having irregularities has a low surface on the side having no irregularities. It is a laminate of the moisture-permeable sheets 3. If the sheet in FIG. 1B is also laminated on the heat conductive panel 11 or the like as an adherend, a sealed space containing air is formed. As shown in FIG. 2, the heat insulating composite sheet 1 ′ for building materials of the present invention has a heat insulating sheet 2
On the upper surface of the sheet, a similar uneven sheet 2 ′ faces each other so that each uneven side faces each other, the convex portions are in contact with each other and stacked, and also has a space 4 containing air inside. The structure may be such that the low moisture permeable sheet 3 is further laminated on one side (the upper surface in FIG. 2) of the laminated sheet 2 and 2 ′. The uneven side of either sheet 2 or 2 'may be turned upside down. However, when the upper and lower sides of the lower sheet 2 ′ are turned upside down, the uneven surface is exposed on the lower side, but even in the shape where the uneven surface is exposed, by sticking the surface to the surface of the adherend,
A sealed space 4 containing air can be formed.

FIG. 3 shows a heat-insulating sheet 2 having irregularities on both upper and lower surfaces in which low moisture-permeable sheets 3 and 3 'are laminated on both sides, and a space filled with air is formed on both sides of the heat-insulating sheet 2. It is formed in. The sheet 2 and the sheet 2 ′ in FIG. 2 may have the same structure by laminating surfaces having no irregularities. One or two low moisture permeable sheets may be omitted, but the uneven side is exposed.
By attaching this exposed surface to the surface of a building material or the like, a sealed space 4 containing air can be formed between the building material and the uneven sheet 2. Incidentally, the two heat insulating sheets 2 and 2 ′ in FIG. 2 have grooves that are parallel and equidistant from each other, the cross section of the grooves is rectangular, and the portion between the grooves rises at right angles to the sheet. The tops are flat, and the sheet 2 and the sheet 2 'are formed so that the directions of the respective grooves are parallel to each other, and the tops of the sheets 2 and 2' are brought into contact with each other. As shown in FIG. 4, the sheet 2 and the sheet 2 'may be stacked such that they face each other so that the directions of the grooves are orthogonal to each other, and are stacked.

As the heat insulating sheet used in the present invention,
Since a sheet with irregularities is used on the surface of the sheet, if this irregular surface is covered with another sheet, many air-filled spaces are formed. By laminating on the adherend, a large number of air-filled spaces are formed, and the sheet has heat insulating properties. Therefore, even if the sheet itself is made of a material of a good conductor of heat, the space occupied by air, which is difficult to conduct heat, occupies a large proportion, so that the heat insulating property is enhanced. However, in order to maintain the strength and shape retention of the heat-insulating sheet itself, a connected portion of the material is required, and there is a contradiction that the portion transmits heat. Therefore, it is preferable to select a material having low thermal conductivity as much as possible for the heat insulating sheet. In consideration of the formation of irregularities, lamination with other sheets, ease of applying makeup described later, and the like, the heat insulating sheet is preferably made of plastic.

By the way, in the range described with reference to FIGS. 1 to 4, the unevenness of the heat insulating sheet is assumed to be parallel, equidistant, and a groove having a square cross section, but various variations are possible. . 5 (a) to 5 (e) show examples of grooves having other cross-sectional shapes. FIG. 5 (a) has a right-angled triangle, FIG. 5 (b) has an isosceles triangle, and FIG. This shows a trapezoidal cross section. Although FIG. 5D shows a cross section having a semicircular shape, the cross section may be a part of an oval instead of a part of a circle. FIG. 5 (e) has grooves on both sides of the sheet with grooves having an isosceles triangular cross-section. The cross-sectional shape other than the isosceles triangle may be provided on both sides of the sheet. Is also good. Although the above description has been made on the assumption that parallel grooves are formed at equal intervals, the grooves are not straight but may be meandering or curved.

From the viewpoint that an air-filled space can be formed, the shape is not limited to such a groove, but may be a shape in which a number of independent projections and holes are formed. As projections,
In addition to the columnar projections shown in FIG. 5 (f) and the columnar projections having an elliptical cross section, the quadrangular columnar projections shown in FIG. When the plane shape is circular, elliptical, etc., triangle, square, etc., polygon, or
Other forms may be used.

The sheet having irregularities without the heat-insulating composite sheet for building materials or the low-moisture-permeable sheet of the present invention (for the sake of convenience, the term “heat-insulating sheet” includes both of them) will be described later. Since it is laminated on the surface of the building material, it can be used as it is, but it is preferable that it has been subjected to some kind of makeup (or decoration). There are various ways of applying makeup, but coloring, printing,
Embossing or wiping painting is typical, and one or more of these may be arbitrarily selected and applied in combination. FIG. 6 shows the appearance of makeup, and FIG. 6A shows a state in which the heat insulating sheet 1 is colored. The coloring may be applied to the entire heat insulating sheet 1 in the thickness direction, or may be applied to only one surface, as schematically shown in FIG. Further, the protective layer 5 may be laminated, though it may be colored. The lamination of the protective layer 5 is optional, and FIG.
The description given with reference to FIG. 6 (d) is the same as that of FIG. FIG. 6B shows a state in which a pattern is applied by printing on the heat insulating sheet 1. The pattern is composed of the colored layer 6a and the picture 6b, but the colored layer 6a may be omitted. FIG. 6C shows a state in which the emboss 7 is applied, and FIG. 6D shows a state in which the colorant 8 is filled in the portion of the emboss 7 by wiping painting. In the following, the materials constituting each layer, the forming method, and the like will be described. In the case of a composite sheet, one or both of a low moisture permeable sheet and a sheet having irregularities can be subjected to makeup, When a wet sheet is not accompanied, makeup is applied to the sheet having irregularities.

The heat insulating sheet 2 having irregularities on one or both surfaces is preferably made of a plastic sheet or made of a plastic sheet as a base material. As the plastic sheet, a sheet made of the following synthetic resin can be used. That is, polyethylene resin, polypropylene resin, polymethylene 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, polymethyl methacrylate resin, polyethyl methacrylate resin, polybutyl acrylate resin, nylon 6
Or a sheet made of polyamide resin represented by nylon 66, cellulose triacetate resin, cellophane, polystyrene resin, polycarbonate resin, polyarylate resin, polyimide resin, or the like. The surface of these plastic sheets is provided with a concavo-convex shape by using a mold at the time of sheet production or after the sheet production by an embossing method of heating and pressing using a mold.

The heat-insulating sheet may be a plastic sheet having a plastic resin uneven surface formed on one or both sides of the above-mentioned plastic sheet. An embossing method may be used in which a coating film is formed and a mold is used at the time of formation, or an embossing method of heating and pressing using a mold after forming the coating film may be used.

As a method for efficiently forming the uneven coating film,
Apply using a composition mainly composed of a curable compound,
There is a method of imparting unevenness when the composition is cured by a curing means corresponding to the composition. Thermosetting resins such as polyurethane resins, epoxy resins, and acrylic syrup for cast polymerization can be used. As a method having a higher curing rate and a higher mechanical strength of the obtained heat insulating sheet, there is a method using an ionizing radiation-curable resin composition.

As the ionizing radiation-curable resin composition, one obtained by appropriately mixing a prepolymer, an oligomer, and / or a monomer having a polymerizable unsaturated bond or an epoxy group in a molecule is used. Examples of prepolymers and oligomers in the ionizing radiation-curable resin composition include unsaturated polyesters such as condensates of unsaturated dicarboxylic acids and polyhydric alcohols, polyester methacrylates, polyether methacrylates, polyol methacrylates, melamine methacrylates and the like. Examples include acrylates such as methacrylates, polyester acrylate, epoxy acrylate, urethane acrylate, polyether acrylate, polyol acrylate, and melamine acrylate, and cationic polymerization type epoxy compounds.

Examples of the monomer in the ionizing radiation-curable resin composition include styrene monomers such as styrene and α-methylstyrene, methyl acrylate, and acrylic acid-2-
Acrylic esters such as ethylhexyl, methoxyethyl acrylate, butoxyethyl acrylate, butyl acrylate, methoxybutyl acrylate, phenyl acrylate, methyl methacrylate, ethyl methacrylate, propyl methacrylate, methoxyethyl methacrylate, methacrylic acid Methacrylic esters such as ethoxymethyl, phenyl methacrylate and lauryl methacrylate; 2- (N, N-diethylamino) ethyl acrylate; 2- (N, N-dimethylamino) ethyl acrylate; -2 acrylic acid -(N, N-dibenzylamino) methyl, unsaturated substituted substituted alcoholic esters such as 2- (N, N-diethylamino) propyl acrylate, unsaturated carboxylic acid amides such as acrylamide and methacrylamide, ethylene Guri Diacrylate, propylene glycol diacrylate, neopentyl glycol diacrylate, 1,6-hexanediol diacrylate, triethylene glycol diacrylate, and other compounds, dipropylene glycol diacrylate, ethylene glycol diacrylate, propylene glycol dimethacrylate, diethylene glycol Polyfunctional compounds such as dimethacrylate and / or polythiol compounds having two or more thiol groups in the molecule, such as trimethylolpropane trithioglycolate, trimethylolpropane trithiopropylate, pentaerythritol tetrathioglycolate, etc. Is mentioned.

Usually, as the monomer in the ionizing radiation-curable resin composition, one or a mixture of two or more of the above compounds is used as necessary. In order to provide suitability, it is preferable that the content of the prepolymer or oligomer is 5% by weight or more and the content of the monomer and / or polythiol compound is 95% by weight or less. Applying an ionizing radiation-curable resin composition,
When flexibility at the time of curing is required, it is preferable to reduce the amount of monomer or use an acrylate monomer having one or two functional groups. When abrasion resistance, heat resistance, and solvent resistance when applying and curing an ionizing radiation-curable resin composition are required, use ionizing radiation such as using an acrylate monomer having three or more functional groups. It is possible to design a curable resin composition. Here, the functional group is 1
Examples thereof include 2-hydroxyacrylate, 2-hexyl acrylate, and phenoxyethyl acrylate. Examples of those having two functional groups include ethylene glycol diacrylate and 1,6-hexanediol diacrylate. Examples of the compound having three or more functional groups include trimethylolpropane triacrylate, pentaerythritol triacrylate, pentaerythritol tetraacrylate, and dipentaerythritol hexaacrylate.

By using these ionizing radiation-curable resin compositions, they can be cured by applying them to a sheet to be coated and irradiating them with ionizing radiation while being in contact with a mold. As the mold, a sheet-like mold having irregularities, a mold having an irregular mold formed on a cylindrical roller surface, or the like is used.

Since the heat insulating sheet may be of various shapes, it is generally difficult to define it. However, the total thickness of the sheet is about 50 to 2000 μm, more preferably 10 to 2000 μm.
About 0 to 500 μm, the pitch at which the projections are formed is 10 to 2000 μm, and the height of the projections is 20 to 450 μm.
It is preferably about μm.

The low moisture permeable sheet 3 suppresses or substantially eliminates moisture permeation to the adjacent heat insulating sheet 2, and prevents the heat insulating sheet 2 from absorbing moisture to lower the heat insulating property. It is to prevent. The low moisture permeable sheet 3
As shown in FIG. 1, there are cases where the layers are laminated only on one side and cases where the layers are laminated on both sides. The lamination of the low moisture permeable sheet 3 and the heat insulating sheet 2 is performed by applying an adhesive between each other or by heat sealing, but the low moisture permeable sheet 3 is arranged on both front and back surfaces of the heat insulating sheet 2, Moreover, when the end surfaces of the low moisture permeable sheets 3 are sealed by bonding with an adhesive or by heat melting, the low moisture permeable sheet 3 and the heat insulating sheet 2 may not be adhered. In addition, even if the low moisture permeable sheet 3 is laminated, the end surface of the heat insulating sheet 2 is exposed to the air.
If moisture absorption from the end face becomes a problem depending on the shape of the heat insulating sheet, sealing may be performed by applying a resin paint to the end face or melting the material with a flame.

As the material of the low moisture permeable sheet 3, the same material as described above as the material of the heat insulating sheet can be used. If necessary, apply a resin binder paint such as polyvinylidene chloride resin with low moisture permeability, or form a thin film using a metal oxide such as aluminum or a metal oxide such as titanium dioxide. It is preferred to use. Although it is slightly disadvantageous from the viewpoint of thermal conductivity,
From the viewpoint of preventing the heat insulating sheet 2 from absorbing moisture, use of a metal foil or application of a paint using a resin similar to the synthetic resin constituting the above synthetic resin sheet as a binder instead of the sheet is used. A film may be formed and replaced with a low-humidity sheet.

When the heat insulating composite sheet 1 or 1 'for a building material of the present invention is applied to the interior of a building material which is not visible, it is not always necessary to improve the appearance. When applied to the outermost surface, some cosmetic measures should be taken, not only the appearance of the material itself. As described above with reference to the drawings, the makeup includes coloring, printing, embossing, wiping, and the like, and a protective layer may be further laminated thereon.

The makeup may be applied to either the front or back surface of the heat-insulating composite sheet 1 or 1 'for building materials, but if the face on which the makeup is applied faces outward or if it is not. Is applied so that the makeup can be seen through the material. When a protective layer is provided, the protective layer is desirably colorless and transparent or colored and transparent from the viewpoint of ensuring the transparency of the lower layer. The coloring is performed by directly painting or impregnating the heat-insulating sheet 1 or coloring the material constituting the heat-insulating sheet in advance. Alternatively, when the low moisture permeable sheet 2 is laminated and the low moisture permeable sheet 2 is transparent, the sheet 2 may be colored at the time of sheet production, or may be formed into a sheet by dyeing, painting, or the like. , May be colored.
The coloring is performed using a coating composition prepared by kneading a pigment and a dye with a binder resin as required.

Printing may be performed on the heat insulating sheet 1, but when the surface of the heat insulating sheet 1 is uneven,
There is a problem in performing clear printing on that surface, and the transfer effect is better when transferred than when directly printed. At the time of printing, only the pattern may be printed. However, in order to adjust the base color, a uniform colored layer 5a is formed before the pattern 5b is formed.
It is good to print. Since the low moisture permeable sheet 2 has a flat surface, if the low moisture permeable sheet 2 comes to the observation side, it is good to print on the surface. If the low moisture permeable sheet 2 is transparent, Alternatively, printing may be performed on the back surface.

The emboss is usually formed by using a mold roll or by applying heat and pressure using a flat plate-shaped mold. Embossing can be performed on either the heat-insulating sheet 1 or the low-moisture-permeable sheet 2, but may also be performed on the heat-insulating sheet 1 alone or on a composite of the heat-insulating composite sheet 1 or 1 'for building materials. When there is a concern that the heat insulating sheet 1 may be crushed when the heat and pressure of the embossing are applied to the heat insulating sheet, the heat insulating sheet 1 is preferably set to be shallower, but many of the heat insulating sheets have resilience. There are various embossed patterns, including wood grain, stone grain, cloth grain, and others.

After embossing, it may be left as it is,
Wiping painting can be performed to fill the recesses created by embossing with ink-like material, the recesses are deeply colored, and the wiping painting itself is like a squeegee, leaving an ink-like coloring material on the embossed surface. This can be easily performed by scraping, and gives an effect similar to printing.

The above-mentioned coloring, printing, embossing, wiping coating, etc. are performed in any combination to give the appearance design to the heat insulating composite sheet 1 or 1 'for building materials.
In addition, when making the heat insulating sheet 1, an appropriate mark or the like that is formed like a watermark pattern by partially increasing or decreasing the basis weight is also included in the makeup. It is.

The heat-insulating composite sheet 1 for building components of the present invention,
1 ′ or 1 ″ (hereinafter, represented by the sheet 1, but the same can be said for other cases) can be used as a heat insulating material by sticking it to various building materials.
Further, a heat insulating sheet without a low moisture permeable sheet (= a sheet having irregularities) can also be used as a heat insulating material by attaching it to various building materials. FIG. 7 is an example in which the heat-insulating composite sheet 1 for building members is laminated on one surface of a thermally conductive panel 11 in which the plate-like bodies 9 and 9 ′ are laminated on the front and back of the frame 10. Or by physical means such as heat sealing or fastening with an adhesive tape, nail, wire or the like. Such a laminated structure can be used for a door, a wall surface, a ceiling surface, a floor surface, or the like, or a cabinet or the like that requires heat insulation, and can perform heat insulation of a certain large area.

FIG. 8 shows a heat-conductive extruded mold 12 made of aluminum or the like and having one side surface of a hollow prism removed along the length direction and having a constant width near the center. The heat-insulating composite sheet 1 or 1 'for a building component of the invention
It is an example of a heat-insulating building member in which is laminated. Similarly, a heat insulating sheet without a low moisture permeable sheet can be applied. The lamination is preferably performed via an adhesive, but other methods as described above can be used. However, when the present invention is applied to a simple extruded member of a cylinder or a prism, the heat-insulating composite sheet 1 for a building component is made of a heat-shrinkable material, and is formed into a tube slightly thicker than the cylinder or the prism. Lamination without heating is also possible by covering and heating, and other lamination methods can be used. The structure as shown in FIG. 8 depends on the shape and use of the extruded shape 12, but it is necessary to attach the frame of the door itself such as a pillar, a skirting board, a dumbbell, a sill, a sliding door or a hinged door to the building frame. It can be used for frames and the like.

In the present invention, the sheet having irregularities provides heat insulation. However, other types of heat-insulating sheets and sheets having irregularities can be combined. The other types of heat insulating sheets include, for example, fiber sheets such as felt, nonwoven fabric, paper, and cloth, various hollow sheets, foam sheets, and the like. These other types of heat-insulating sheets can be used alone, or two or more sheets can be laminated with one or two or more sheets having irregularities in any order and in any combination of front and back directions. And other types of insulating sheets can complement the advantages and disadvantages, so select the material according to the application,
It is good to use it by laminating it, and in the present invention, although a sheet having unevenness is mainly used, lamination with another kind of heat insulating sheet is not excluded.

As shown in FIG. 5 (b), each of the heat insulating sheets A has an isosceles triangular mountain-shaped cross section, and the height difference between the top of the mountain and the bottom of the valley is 25 μm. , 50μ
A polyethylene terephthalate resin sheet having a total thickness of 150 μm and having irregularities consisting of a number of parallel grooves with a pitch of m was prepared.
