Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating composite sheet for a building member, which can be applied to a building member to give a heat insulating property to the surface thereof and to provide an odor suppressing function, and the building material. The present invention relates to a heat-insulating building member to which a heat-insulating composite sheet for a member is applied.

[0002]

BACKGROUND OF THE INVENTION The primary purpose of buildings is to shield and protect occupants from the outside environment, to prevent wind and rain, and to mitigate changes in temperature. For this reason, various materials that do not leak from the wind, block the wind, and have a certain degree of heat insulating properties have been used for various types of materials that make up buildings. In recent years, not only seasonal heating and cooling, but also air conditioning for maintaining a comfortable living environment throughout the year and 24 hours has led to an increase in energy consumption. Improvements are being made.

[0003] The space between the outer and inner walls of the building is filled with a heat insulating material, and measures are taken to prevent the temperature inside the building from excessively rising and falling. However, opening members such as doors, glass doors and windows are used. Have not taken sufficient insulation measures. In particular, Japan is located in a temperate zone, so the annual sunshine hours are long,
Since ventilation is required in the summer, it is common to make the opening larger 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 the use of aluminum or PVC, aluminum is often used, and aluminum is a good conductor of heat, so it can easily conduct heat. Aluminum building components have the following advantages: they are resistant to rust, do not rot, are lightweight and easy to install and use, have a clean feeling, and do not require painting.On the other hand, they are good conductors of heat In winter or the like, a low outdoor temperature is transmitted, the surface of the indoor side becomes low temperature, and moisture in the indoor air is condensed and adheres as water droplets, which may eventually flow down. If aluminum is replaced with iron, it is somewhat difficult to conduct heat, but iron is not a poor conductor of heat, and there is essentially no difference.

[0005] There is a method of blocking the front and back of the building member with plastic or the like, or using a double or triple building member as in a cold region. However, according to the former method, the building member is not used. According to the latter method, there is a disadvantage in that the thickness occupied by a thermally conductive metal such as aluminum among the building components increases, and the cost is increased by using the material twice or three times. Disadvantages are inevitable.

There is a problem with odor from the viewpoint of seeking a better environment from a viewpoint different from heat insulation. There are various sources and sources of odors, but specific odorous substances are regulated, but odors that are liable to occur in daily life are not always thoroughly protected. Causes of odors in buildings include food or luxury goods, garbage, excrement of livestock, dirt, sweat, or fat in bathrooms, or those that have been altered by the action of their oxides or bacteria. There is. In particular, the smell of ammonia or mercaptan is a problem as the odor around us. As a countermeasure against odor, there is a method to eliminate the cause by decomposing substances that generate odor or a substance that forms odor, and to convert the odor once generated into another form or decompose by chemical reaction etc. to eliminate the odor There is a method, and in addition, generation of another odor that counteracts odor is performed.

Attempts to deodorize and deodorize building components have been around for a long time, and various substances have been known for that purpose. However, as a practical application method, they are housed in a container and used as a source of odor generation. There are a method of placing it near, and a method of attaching it to a filter or the like of an air circulation device such as an air conditioner. by the way,
Opening members are used at the point of contact between different environments, windows and entrance doors are located at the boundary between the outside world and the room, and indoors, between the space of the room or corridor and the space of other rooms, bathrooms, toilets, etc. positioned. Therefore, when an odor generated in a specific place indoors moves to another place, it passes through these opening members having a small cross-sectional area. The significance of having the function is high. However, applying to the opening member, deodorant,
There has been no heat-insulating composite sheet for a building member that gives a deodorizing function and can be performed simultaneously with the heat insulating property, and no heat-insulating building member to which such a sheet is applied.

[0008]

Accordingly, in the present invention, 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. The goal is to minimize the conduction of heat, especially the low temperature of outside air, to the inside of a building without suppressing the conduction of heat, and to provide deodorizing and deodorizing functions to building components. It is.

BEST MODE FOR CARRYING OUT THE INVENTION A heat insulating composite sheet 10 for a building component according to the present invention will be described with reference to FIG. 1 (a). One side of a heat insulating sheet 11 has an odor containing a deodorant or a deodorant. By having a structure in which the suppression layer 12 is laminated (hereinafter, simply referred to as a laminated type), an effect of deodorizing or deodorizing (hereinafter, simply referred to as an odor suppressing effect) is exhibited. This laminated structure usually has a heat insulating sheet 1
One side is used while being directed to the target side to be provided with thermal insulation. The odor suppressing layer 12 can be laminated on both sides of the heat insulating sheet 11. If the heat-insulating sheet 11 itself has the permeability of a substance, even if the odor suppressing layer 12 is laminated on both front and back surfaces (not shown), when the odor-suppressing layer 12 is attached to the target side to which the heat insulating property is to be imparted. Then, from the odor suppression layer 12 inside,
This is because it is expected that an odor suppressant composed of a deodorant or a deodorant (hereinafter, simply referred to as an odor suppressant) will migrate to the outside over time and exert an odor control effect. Further, when the heat insulating sheet 11 has impregnation properties, the heat insulating sheet 11 can be impregnated with the odor suppressing agent (hereinafter simply referred to as impregnating type) without the odor suppressing layer 12 being laminated as described above. ) Can exert an odor control effect (FIG. 1 (b)). The hatching in FIG. 1 (b) represents the impregnated odor suppressant.

Fig. 2 is a graph showing the relationship between the laminated type and the impregnated type.
(A) or as shown in FIG. 2 (b), a low moisture permeable sheet 13 may be laminated on one side, or low moisture permeable sheets 13 and 13 'may be laminated on both sides. . However, when the heat-insulating composite sheet for a building component is an impregnated type as described with reference to FIG. 1 (b), when the low moisture-permeable sheets 13 and 13 'are laminated on both sides, the internal In this case, the lamination of the low-moisture-permeable sheet 13 is limited to only one side because the effect of the odor suppressant does not reach the outside. FIG.
In the case of the laminated type described with reference to (a), there is no problem even if the low heat permeable sheets 13 and 13 ′ are laminated on both sides as the heat insulating sheet 11.
In the following description, unless otherwise specified, the heat-insulating composite sheet 10 for building components is a laminated type and an impregnated type as described with reference to FIGS. 1 and 2, and It is assumed that they include all of the low moisture permeable sheets 13 laminated.

Examples of the material of the heat insulating sheet 11 include a resin in which a heat insulating portion is dispersed, such as a foamed resin, a resin in which hollow particles are dispersed instead of air bubbles, or a resin in which hollow fibers are dispersed, a woven fabric, a nonwoven fabric, or the like. Fibers such as paper or felt, sheets with fine prism-shaped cross sections, sheets with countless minute projections on the surface, or sheets with many low columnar bubbles sealed between laminated films Etc. The thicker the heat insulating sheet 11, the higher the heat insulating effect.
Depending on the application, thicker may hinder use,
In the case of applying to a relatively small area such as a fitting, both of the heat insulating layer 12 and the heat storage layer 11 are 10 to 200
The thickness is preferably about μm, but may be more if the thickness is not restricted.

The odor control agents which provide the odor control function by being laminated or impregnated on the heat insulating sheet 11 are roughly classified into (1) microorganisms or enzymes, (2) plant extract components,
(3) Enzyme-like compounds, (4) Others. Unless these (1) to (4) interfere with each other,
Each of the groups (1) to (4) or different groups can be used in combination.

Examples of the microorganism or enzyme of (1) include microorganisms belonging to the genus Pseudomonas, and enzymes such as proteinases called proteases or malodorous enzyme. These microorganisms or enzymes are used as they are, or mixed, adsorbed or carried on mineral substances, or immobilized by other methods. As similar to microorganisms or enzyme systems, fermentation products of foods and brewed products, fermentation products of sludge and other organic wastes, etc. can be used.Furthermore, humic substances and earthworm feces, etc. Within the range of system odor control agents.

There are various plant extraction component systems (2). Most of them are obtained by solvent extraction from plants and are derived from natural products and are said to be highly safe. There are many types, but typical ones are as follows; Camellia family (Camellia, Cha, Sazanka, Sakaki, Hisakaki), Shin family (Sage, Rosemary, Thyme, Mentha), Camphor tree family , Butterfly, Nikkei), Rutaceae (Sansho, Orange), Oysteraceae, Legume (Acacia genus, Licorice, Soybean, Suo), Pinaceae (Pinus sylvestris, Pinus serrata, Tsutsumi, Nishikimatsu), Rosaceae (Prunus genus, Neubara) ), Fagaceae (Chrysanthemum, Querzas, Quercus), Cryptomaceae, Laceae (Forsythia, Holly Mokusei, Lilac, Sinenenyou, Kobanotoneriko), Salixaceae (Salix), Futomomochi (eucalyptus), Magnolia (Frontaceae) , Japanese cypress (Hinoki, Asunaro, Konotegashiwa), Poaceae (Sasa, bamboo, ko , Wheat, corn), polygonaceae (Polygonum, rhubarb), bellflower family (oleander), lichens (hemp beard lichen, key Parmeliaceae, Moegi goose bumps moss), Malvaceae (Hibiscus)

Examples of the odor suppressants based on plant extracts derived from plants as described above include anisaldehyde, heliotropin, vanillin, coumarin, carvone, cinnamaldehyde, perilaldehyde, citral, cuminaldehyde, croton and the like. Compounds having activated double bonds, which react with thiols and amines by addition reaction or dehydration condensation reaction to remove odor. The compound having a carbonyl group contained in the plant extract component-based odor suppressant undergoes a dehydration condensation reaction with thiols and amines,
Remove odor. Further, the carboxylic acid, cyclic ether, acidic OH group contained in the odor suppressant of the plant extract component system,
Alternatively, the polyphenol removes the odor by a neutralization reaction with the compound causing the odor or by the formation of a molecular compound by hydrogen bonding with a weakly basic amine. Examples include compounds having a carboxylic acid, 1,8-cineole in eucalyptus, laurel, and Spanish sage. Alternatively, the hydrogen at the allylic position of abietic acid contained in many plants is extracted by O ₂ to form a radical (ROO.)
And reacts easily with mercaptans, phenols, or anilines. In addition, among the plant extract components, proteins,
Some bacteria and molds that degrade higher fatty acids or carbohydrate macromolecules to produce malodorous substances have antibacterial and antifungal effects, and do not directly decompose malodorous substances. Has a deodorant function.

(3) Enzyme-like compounds are biomimetic odor inhibitors that mimic enzyme reactions with stable chemicals. For example, octacarboxylic acid or tetracarboxylic acid of iron phthalocyanine has properties similar to those of catalase and oxidase, which are H ₂ O ₂ degrading enzymes, and has a wider application range with respect to temperature, pH, and the like than natural enzymes. In addition, iron-ascorbic acid also mimics biological reactions having neutralization and sulfide formation reactions, and is safe and inexpensive.

(4) Others include cyclodextrins, which take in malodorous substances into hydrophobic cavities in the molecule, form inclusion compounds, and remove odors. Used in the field.

In order to apply the above-mentioned odor suppressing agents to the heat insulating sheet 11, these odor suppressing agents are used in a solvent, and if necessary, dissolved or dispersed together with a binder resin and additives to form an ink or paint. Using the obtained ink or paint, printing or applying or impregnating on the heat insulating sheet 11, and then drying. Alternatively, these odor suppressing agents may be melt-kneaded with a resin and extruded from a slit to form a film and laminate the film, or the film may be formed and laminated once.

Various binders can be used as a binder which may be added at the time of coating, for example, the following: rosin-modified maleic resin, nitrocellulose resin, cellulose acetate resin, butyric acid Cellulose resin, ethyl cellulose resin, polyamide resin, chlorinated polypropylene resin, polyvinyl chloride resin, vinyl chloride /
Acrylic resin such as vinyl acetate copolymer resin, ethylene / vinyl acetate copolymer resin, ethylene / ethyl acrylate copolymer resin, polymethyl methacrylate, polyurethane resin,

Butadiene rubber, chloroprene rubber, butyl rubber, polysulfide rubber, silicone rubber, polyurethane rubber,
Stereo rubber (synthetic natural rubber), ethylene propylene rubber, block copolymer rubber (SBS, SIS, SEB)
S) and the like. In addition to these, an ionizing radiation-curable resin composition that crosslinks and cures upon irradiation with ionizing radiation such as ultraviolet light or an electron beam may be used, and if possible, between an odor suppressant and the ionizing radiation-curable resin composition. Should be designed to have a chemical bond.

The odor control agent and the above-mentioned binder are preferably added and used in a proportion of 50 to 1000 parts by weight based on 100 parts by weight of the binder. When the odor control agent is formed on the heat insulating sheet 11 as the odor control layer 12, the heat insulating sheet 11 may be applied by an appropriate method, or may be coated on a temporary base material having a peelable surface. After coating and forming a film, the heat-insulating sheet 11 is peeled off from the base material.
And laminating them. When the heat insulating sheet 11 is a laminate with the low moisture permeable sheet 13, the heat insulating sheet 11 may be applied or laminated on the low moisture permeable sheet 13, but before the lamination with the heat insulating sheet 11. The odor suppressing layer 12 may be laminated on the low moisture permeable sheet 13 by coating or laminating first, and then laminated on the heat insulating sheet 11. In the above description, both lamination and impregnation by coating have been described to be performed uniformly and uniformly. However, if necessary or for reasons of external design, a uniform layer should be formed. No, stripes, grids consisting of vertical and horizontal lines, polka dots, etc.
It may be formed in various patterns. The odor control layer 12 has been described as a single layer. However, in the case where two or more odor control agents are used and there is a problem when they are mixed, the odor control layer is divided into two or more layers. May be formed. Further, the odor control agent is contained with a concentration gradient in the thickness direction of the odor control layer. For example, the odor control agent is contained in such a manner that the concentration becomes lower as the surface becomes closer to the surface, and the odor suppressant is gradually transferred to the surface. May be maintained. It is more preferable that a barrier layer is formed below the odor control layer 12 (on the side opposite to the surface) so that the odor control agent does not migrate to the adjacent layer from the side having the higher concentration.

The heat storage composite sheet 10 for a building component of the present invention
When used for a long period of time, or when used in a place where people or objects are likely to come into contact, the strength is low, and there is a lot of risk of damage and impairing heat insulation. For this reason, it is preferable to coat the heat insulating composite sheet 10 for building components with an appropriate sheet, and the sheet to be coated is impermeable to moisture in consideration of the application.
It is preferable to use the low moisture permeable sheet 13. In addition,
When the low moisture permeable sheets 13 and 13 'are laminated on both sides of the heat storage composite sheet 10 for building components, the ends of the low moisture permeable sheets 13 and 13' are heat-sealed or bonded together. The heat insulating sheet 12 is made of two low moisture permeable sheets 1
Sealing with 3, and 13 'is preferable because moisture can be prevented from entering the heat insulating sheet 11 from the end face.

The low-moisture-permeable sheet 13 suppresses or substantially eliminates moisture permeation to the adjacent heat-insulating sheet 11 and prevents the heat-insulating sheet 11 from absorbing moisture to prevent the heat-insulating property from being reduced. Things. The low moisture permeable sheet 13 is
There are cases where the heat insulating composite sheet 10 for building parts is laminated only on one side and cases where it is laminated on both sides. When laminated only on one side, it is used in an environment where the degree of moisture absorption is large. If it is anticipated that an external force will be applied, it is preferable to apply the low moisture-permeable sheet 13 in consideration of the orientation so that the side on which the low moisture-permeable sheet 13 is not laminated is the target side to be pasted. Low moisture permeable sheet 13 and heat insulating sheet 11
Is laminated using an adhesive or by heat sealing. However, when the low moisture permeable sheets 13 and 13 ′ are arranged on both the front and back surfaces of the heat insulating composite sheet 10 for building components and the end faces of the low moisture permeable sheets 13 and 13 ′ are sealed, the low moisture permeability sheet 13 The wet sheet 13 and the heat insulating composite sheet 10 for building components may not be bonded. In general, even if the low moisture permeable sheet 13 is laminated, the end surface of the heat insulating composite sheet 10 for a building component is exposed to the air. Sealing may be performed by applying a resin paint or melting the material with a flame.

As a material of the low moisture permeable sheets 13 and 13 ', for example, a plastic film is preferable. As the plastic, a polyethylene resin, a polypropylene resin, a polymethylene resin, a polymethylpentene resin, a polyvinyl chloride resin, a polyvinylidene chloride is used. 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, polyamide resin represented by nylon 6 or nylon 66, cellulose triacetate resin,
Examples include cellophane, polystyrene resin, polycarbonate resin, polyarylate resin, and polyimide resin.

The low moisture permeable sheet 13 is coated with another paint prepared by using a resin binder such as polyvinylidene chloride resin having low moisture permeability, or by forming a thin film of metal or metal oxide to form a gas permeable sheet. Should be suppressed. In these metal thin films, 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 a mixture mainly composed of an inorganic oxide may be used. May be bonded to an organic group.

As a method of forming a thin film, for example, a vacuum deposition method such as an ion beam method or an electron beam method, a physical vapor deposition method such as a sputtering method, a plasma chemical vapor deposition method, or a thermal chemical vapor deposition method Or a chemical vapor deposition method such as a photochemical vapor deposition method. The thickness of the thin film is
Preferably, it is 50-3000 °, more preferably 100-1000 °. 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. Although slightly disadvantageous in terms of thermal conductivity, from the viewpoint of preventing the heat insulating sheet 21 from absorbing moisture, a metal foil is laminated or the same as the synthetic resin constituting the above synthetic resin sheet. It is also possible to form a coating film of a paint using a resin as a binder and to replace the low humidity sheet.

The heat-insulating composite sheet 10 for building components of the present invention
Is laminated on the surface of the building component and is exposed to the outermost layer, as described later, and is desirably provided with some makeup (also referred to as decoration). There are various ways of applying makeup, but coloring, printing, embossing, or wiping painting is typical, and one or two of them can be arbitrarily selected from these.
More than one species may be applied in combination.

FIG. 3 shows the appearance of makeup.
(A) shows a state in which the heat insulating composite sheet 10 for a building component is colored. The coloring may be applied to the entire heat insulating sheet 10 in the thickness direction, or may be applied only to one surface on the observation side, as schematically shown in FIG. Further, although it may be merely colored, the protective layer 2
May be laminated. The lamination of the protective layer 2 is optional, and the description given with reference to FIGS. 3 (b) to 3 (d) is not repeated, but is the same. FIG.
(B) shows a state in which a pattern is applied by printing on the heat insulating sheet 10. The pattern is composed of the colored layer 3a and the picture 3b, but the colored layer 3a may be omitted. FIG. 3 (c)
3 shows a state in which the emboss 4 has been applied, and FIG. 3D shows a state in which the colorant 5 is filled in the portion of the emboss 4 by wiping painting.

The part to be decorated may be on either the front or back surface of the heat insulating composite sheet 10 for a building component. However, if the face on which the decoration is made faces outward, or if not, Apply so that the makeup can be seen through the material. When covering the cosmetic with the protective layer 2, the protective layer 2 is desirably colorless and transparent or colored and transparent from the viewpoint of ensuring the transparency of the lower layer.

The protective layer 2 may be composed of a coating film of a synthetic resin paint, or may be composed of a laminate of synthetic resin films in some cases. As the coating film of the synthetic resin paint, a coating material using a thermoplastic resin may be used, but a coating film obtained by curing a thermosetting resin such as a polyurethane resin is excellent in terms of durability. Alternatively, when the coating composition is formed by applying the ionizing radiation-curable resin composition prepared by using the prepolymer and crosslinking and curing by irradiation with ionizing radiation, the protective effect of the lower layer is further improved.

The coloring is performed on the heat insulating composite sheet 10 for building components.
The material constituting one or both of the heat insulating sheet 12 and the low moisture permeable sheet 13 is colored in advance. Alternatively, the sheet is colored at the same time as the production of the material film, or after the sheet is formed, the sheet is colored by dyeing, painting, or the like. In addition, coloring is a pigment,
This is carried out by using a coating composition prepared by kneading a dye with a binder resin as required.

The printing is performed on the heat insulating composite sheet 10 for building components.
Heat-insulating composite sheet 10 for building parts
If the surface on the observation side has a concave-convex shape, there is a problem in performing clear printing on that surface. In such a case, the printing effect is improved by directly transferring the image instead of printing. If one side has no irregularities, it may be printed on the side without irregularities as long as it is printed there and viewed from the observation side. At the time of printing, only the pattern may be printed. However, in order to adjust the base color, a uniform colored layer 3a is formed before the pattern 3 is formed.
Print b. As the low moisture permeable sheet 13, it is common to use a flat surface, so that the low moisture permeable sheet 13 may be printed on the surface as long as the low moisture permeable sheet 13 is on the observation side. If so, printing on the back surface may be performed.

The emboss is usually formed by using a mold roll or by heating and pressing using a flat plate-like mold. Embossing can be performed on any of the laminated heat insulating composite sheet for building components 10, the heat storage layer 11, the heat insulating layer 12, or the low moisture permeable sheet 13, and is not necessarily formed on the surface but formed inside. Sometimes. When there is a concern that the heat insulating composite sheet for building members 10 may be crushed when the heat and pressure of embossing are applied to the heat insulating composite sheet 10 for building members, it is preferable to perform the heat insulating process at a shallower depth. Many resilient sheets are resilient. 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. The wiping paint itself,
The ink-like colorant 5 is applied to the embossed portion 4 and scraped off with a squeegee or the like, which can be easily performed and has an effect similar to that of printing. , More depth. The above-mentioned coloring, printing, embossing, wiping painting, etc. are performed in any combination, and the heat insulating composite sheet 1 for building materials is used.
In addition to the feeling of the material, it gives the appearance design.

The heat-insulating composite sheet 10 for building members of the present invention
Can be used as a heat insulating material by sticking it to various building components. FIG. 4 shows that the heat-insulating composite sheet 10 for building members is laminated on one side of a thermally conductive panel 8-like building member in which the plate members 7 and 7 ′ are laminated on the front and back of the frame 6,
Alternatively, it is an example of further insulating properties, the lamination is an adhesive,
It may be performed with an adhesive, heat sealed, or fixed with an adhesive tape, a nail, a wire, or the like. For this reason, an adhesive is preferably applied to the insulating composite sheet for building members 10 in advance, and the same applies to another type of building member described with reference to FIG. When the heat insulating composite sheet 10 for a building component includes the heat insulating layer 12, the heat insulating layer 12 is laminated so that the heat insulating layer 12 side faces the building component. This is the same in the following description using FIG. The structure as shown in FIG. 4 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 perform heat insulation to a certain extent.

FIG. 5 shows a surface of a heat-conductive extruded member 9 made of aluminum or the like, which has one side surface of a hollow prism removed along the length direction and a fixed width near the center.
It is an example of a heat-insulating building member in which the heat-insulating composite sheet for building members 10 of the present invention is laminated. The shape of the extruded material 9 may be another shape. The lamination may be performed via an adhesive or an adhesive, but other methods can be used. However, in the case of a simple cylinder or prism, the heat-insulating composite sheet 10 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.
