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.

[0007]

In the present invention, various heat-insulating materials have been studied. When a sheet having a gap formed by using a spacer is used as a heat-insulating material, these materials are resistant to compression, Therefore, it has been found that the heat insulating property does not decrease over time during use, and that good heat insulating property can be maintained, leading to the present invention.

FIG. 2A shows a cross section, and FIG.
FIG. 2A is a plan view of the one shown in FIG. As shown in FIG. 3, the heat insulating composite sheet 1 for a building component of the present invention includes:
The hair-like projections 33 are formed on the low moisture-permeable sheet 21.
May have a spacer structure composed of a large number of structures fixed in a direction perpendicular to the direction. Alternatively, as shown in FIG. 4, the heat-insulating composite sheet for a building component of the present invention has a wire-like structure forming a net by bonding a very coarse net-like net 34 on the low moisture-permeable sheet 21. And a spacer structure resulting from the intersection of the lines.

FIGS. 1 (b) to 1 (b) show that the spacer particle 31, the spacer body 32 or the spacer structure is
It may have a sandwich structure in which another low moisture permeable sheet 21 'is laminated. In the drawings, including the following, 1 is 1
A heat insulating composite sheet for building members having two low moisture permeable sheets 21, and reference numeral 1 ′ is a heat insulating property for building members having two low moisture permeable sheets 21 and 21 ′. Refers to composite sheet.

The spacer particles 31 are inorganic particles such as silica and alumina, shirasu balloons, plastic beads such as acrylic resin and polystyrene resin, or chips or rubber particles.
It is preferably about 0 μm to 2 mm. For the purpose of lowering the thermal conductivity, it may be hollow or foamed and contain air bubbles. A spherical shape is easy to handle, but a shape other than a spherical shape may be used. It is also possible to use a thin rod-like material having a circular cross section or a chip-like material obtained by cutting a tubular material. In order to apply these spacer particles 31 on the low moisture permeable sheet 21, a coating film that can serve as an adhesive is formed on the low moisture permeable sheet 21,
It is possible to use a method of spraying the spacer particles 31 while being tacky, or dispersing the spacer particles 31 in the synthetic resin coating composition and applying them.

As the spacer body 32, a plastic rod, a hollow rod, a tube obtained by slicing a tube to a length of a fraction of a diameter, or a sheet formed from a sheet is punched into a predetermined shape. It is preferable to use a small piece of the above and apply it on the low moisture permeable sheet 21 in the same manner as the spacer particles 31.

As the spacer structure, as the one in the range of the hairy projection 33, a structure such as a brush surface on which natural fibers or synthetic fibers of a predetermined length are planted, or a flocking structure by electrostatic flocking Etc. The length of the fiber is preferably 20 μm to 1 mm, and the diameter of the fiber is preferably 5 μm to 100 μm, depending on the planting density. In addition, the net-like material may be formed by using a natural fiber or a synthetic fiber as a material, or a stripe coat of a synthetic resin paint or an adhesive. As a net, the fibers used are about 20 μm to 1 mm and the aperture ratio is 20
% To about 80% is preferable. In addition, as a structure resembling a net, a perforated sheet may be used in which fibers or thin rods are arranged on the low moisture permeable sheet 21 at intervals.
It is not always necessary to align the height and width. In addition to these, there is a sheet in which through holes are formed at appropriate intervals in a sheet having an appropriate thickness. Alternatively, when the surface of the thermoplastic resin sheet is blown with hot air at a temperature at which the resin melts, the molten resin is spread by the wind to give a brush-like surface, but such a material can also be used. It is. If necessary, the spacer structure as described above may be formed using the low moisture permeable sheet 21 as a base material.

Another sheet having a spacer structure may be laminated between the sheet and the low moisture permeable sheet 21 ′ by interposing an adhesive or the like. Since these sheets having a spacer structure are continuous, they have shape retention properties as compared with the other types described as spacer particles and spacer bodies, and have a strength as a heat insulating composite sheet for building components. And easy to manufacture.

The heat insulating composite sheet 1 or 1 'for building materials of the present invention is to be laminated on the surface of the building member as described later, so that some kind of makeup (or decoration) may be applied. It is desirable that it is done. There are various ways of applying makeup, but coloring, printing, embossing,
Alternatively, wiping coating is typical, and one type or a combination of two or more types is arbitrarily selected from these. FIG. 5 shows the appearance of makeup, and FIG.
Indicates a state in which the heat insulating composite sheet 1 or 1 'for building components is colored. As shown in FIG. 5 (a), coloring may be applied to the entire heat insulating composite sheet 1 or 1 'for a building member in the thickness direction, or may be applied to only one surface. . Further, the protective layer 2 may be laminated, although it may be colored. The lamination of the protective layer 2 is optional, and the description given with reference to FIGS. 5B to 5D will not be repeated in each case.
The same is true. FIG. 5 (b) shows a state in which a pattern is applied by printing on the heat insulating composite sheet 1 or 1 'for a building component. The pattern is composed of a colored layer 3a and a picture 3b.
The coloring layer 3a may be omitted. FIG. 5C shows the emboss 4
5D shows a state in which the colorant 5 is filled into the embossed portion 4 by wiping painting. Hereinafter, the materials constituting each layer, the forming method, and the like will be described.

The low moisture permeable sheets 21 and 21 ′ protect the spacer particles, the spacer body, or the portion having the spacer structure, or suppress or substantially eliminate the moisture permeability. The absorption prevents the heat insulation from being reduced. The low moisture permeable sheets 21 and 21 ′ are, as shown in FIGS.
There are cases where the layers are laminated only on one side and cases where the layers are laminated on both sides. When used in an environment where there is a concern that the degree of moisture absorption is large when only one side is laminated, one of the low moisture permeable sheets 21 and 21 ′ that is not laminated should provide heat insulation. It is preferable to apply in consideration of the direction so as to be on the target side. Lamination of the low moisture permeable sheets 21 and 21 ′ and the portion having the spacer particles, the spacer body, or the spacer structure is performed by using an adhesive or by heat sealing. When both are used, and when the end faces of the low moisture permeable sheets 21 and 21 ′ are joined together and sealed with an adhesive, a heat seal or the like, either one of the low moisture permeable sheets 21 and 21 ′, or Both may not adhere to the spacer particles, the spacer body, or the portion having the spacer structure.

As the low moisture permeable sheets 21 and 21 ', plastic sheets made of the following synthetic resins 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 na Phthalate-isophthalate copolymer resin, polymethyl methacrylate resin, polyethyl methacrylate resin, polybutyl acrylate resin, polyamide resin represented by nylon 6 or nylon 66, cellulose triacetate resin,
The sheet is made of cellophane, polystyrene resin, polycarbonate resin, polyarylate resin, polyimide resin, or the like.

The above low moisture permeable sheets 21 and 21 ′ include:
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 slightly disadvantageous in terms of thermal conductivity, a metal foil is further laminated from the viewpoint of preventing the spacer particles 31, the spacer body 32, or the spacer structure denoted by reference numeral 33 or 34 from absorbing moisture. Alternatively, a low-humidity sheet may be formed by forming a coating film of a paint using a resin similar to the synthetic resin constituting the above-mentioned synthetic resin sheet as a binder.

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 member which is invisible to the public, it is not always necessary to improve the appearance, but it is necessary to improve the appearance of the building material. When applied to the outermost surface, some cosmetic measures should be taken, not only the appearance of the material itself. As described earlier with reference to the figures, coloring, printing,
There is embossing, wiping painting, or the like, on which a protective layer may be further laminated.

The makeup may be applied to either the front or back surface of the heat-insulating composite sheet 1 or 1 'for a building component, but if the face on which the makeup is applied faces outward or if it is not so. 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. Coloring may be performed by painting, printing, or the like on the front surface or the back surface of the low moisture permeable sheets 21 and 21 ', or may be colored in advance when preparing the material of the low moisture permeable sheets 21 and 21'. Coloring is performed using a coating composition prepared by kneading pigments and dyes with a binder resin as necessary.

The printing may be performed on the low moisture permeable sheets 21 and 21 ′ of the heat insulating composite sheet 1 or 1 ′ for a building component. However, in the case of having the spacer particles 31, the spacer body 32, or the spacer structure, Since the surface also has an uneven shape derived from them, there is a problem in performing clear printing on the surface, and the transfer effect is higher when the transfer is performed than when the print is performed directly. When printing, only the pattern may be printed,
In order to adjust the base color, it is preferable to form the uniform colored layer 5a before printing the pattern 5b. As the low-moisture permeable sheets 21 and 21 ′, usually, a flat surface is used. Therefore, if the low-moisture-permeable sheet 2 comes to the observation side, it is good to print on the surface. May be printed on the back surface.

The emboss is usually formed by using a mold roll or heating and pressing using a flat plate-shaped mold. Embossing can be performed on the entire heat insulating composite sheet 1 or 1 'for building components via the low moisture permeable sheets 21 and 21'. However, embossing is performed on the low moisture permeable sheet in advance and embossed. May be laminated to form a heat insulating composite sheet for building components. When the heat and pressure of the emboss are applied, if there is a concern that the heat-insulating composite sheet for building components may be crushed, it is better to perform it shallower,
This does not apply if there is 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, and the recesses are deeply colored. 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.

The heat-insulating composite sheet 1 or 1 'for a building component of the present invention can be used as a heat-insulating material by attaching it to various building materials. FIG. 6 shows a plate-like body 7 on the front and back of the frame 6.
And 7 'are laminated on one side of a thermally conductive panel 8 on which a heat insulating composite sheet 1 (or 1', represented by 1 in the following description) is laminated. Yes, the lamination may be performed via an adhesive, heat sealed, or fastened with an adhesive tape, nail, wire or the like. Such a structure can be used for a door, a wall surface, a ceiling surface, a floor surface, or the like, or for a cabinet or the like that requires heat insulation, and can provide heat insulation to a certain extent. The heat-insulating composite sheet 1 or 1 'for building components may be applied to both sides.

FIG. 7 shows a surface of a heat-conductive extruded material 11 made of aluminum or the like and having one side surface of a hollow prism removed along the length direction and near the center with a constant width. It is an example of the heat-insulating building member in which the heat-insulating composite sheet 1 for a building member of the present invention was laminated. Again, lamination may be via an adhesive, but other methods are possible. However, in the case of a simple cylinder or prism, the heat-insulating composite sheet 1 for a building component is made of a heat-shrinkable material, formed into a slightly thicker tube than the cylinder or prism, covered, and heated. Thus, lamination without necessarily using an adhesive is also possible, and lamination methods other than these can be adopted. The structure shown in FIG.
Although it depends on the use of (1), it can be used as a frame of a door, a frame for attaching a door, such as a pillar, a skirting board, a sill, a sill, a sliding door, a hinged door, and the like.
