Description

  The present invention relates to a vacant window sheet having a function of shielding ultraviolet rays from the outside by pasting in accordance with the size of a vacant window.

  In apartments, condominiums, etc., stores, buildings, etc., if there are no occupants, the space is vacant. There are no curtains or the like in the vacant windows, and as a result, the interior and tatami mats cause discoloration deterioration and the like due to ultraviolet rays poured from the windows.

  Therefore, as a countermeasure for preventing discoloration deterioration due to ultraviolet rays, means for shielding ultraviolet rays by covering a window with a curing curtain or laying a sunscreen sheet on the floor is used only during the vacant period.

  However, the curtain has a function of limiting the transmission of ultraviolet rays from the outside depending on the thickness of the fabric. In the curtain of a thick fabric, it hardly transmits ultraviolet rays, but in the case of a thin fabric, the ultraviolet rays are transmitted through the thick fabric. Will be more transparent than Therefore, in order to make it difficult for UV rays to pass through, it is necessary to make the cloth of the curtain thicker, but it is not economical, the room becomes dark, and it is necessary to open the curtain or turn on the room lighting to make it brighter .

  Therefore, curtains that limit the transmission of ultraviolet rays regardless of the thickness of the fabric have been proposed (see Patent Document 1 and the like).

  However, even when using these UV-shielding curtains, it is necessary to open the curtains or turn on indoor lighting when making the room brighter. In addition to the need to adjust the dimensions according to each window so that the width and length are not long or short, there are also cost problems.

Also, when a sunscreen sheet is laid on the floor for the purpose of shielding ultraviolet rays, for example, when a person visits a vacant room, it is necessary to clear the sheet each time, which takes time. There is a problem.

  The present invention has been made to solve such problems, and is a vacant window sheet having an ultraviolet shielding function that can be applied to windows of any size without troublesome installation work and size adjustment. It is an issue to provide.

  The gist of the present invention is a sheet for a vacant window, which is a synthetic resin sheet containing an ultraviolet absorber and having an ultraviolet shielding rate of 90% or more and an adhesive strength of 0.015 to 20 N / 25 mm. Is.

  As the synthetic resin sheet, a sheet having an adhesive layer laminated on one surface of the sheet or a sheet having self-adhesiveness is used.

  In addition, it is preferable that the printing layer is formed in one surface of a synthetic resin sheet.

  Moreover, it is preferable that the printing display as a printing layer is repeatedly formed with the same display pattern along the length direction of a synthetic resin sheet.

  Furthermore, the synthetic resin sheet is preferably translucent.

  The vacant window sheet of the present invention can be shielded from ultraviolet rays by cutting and pasting the sheet according to the size of the window, even if you are not a specialist, and sticking the sheet directly to the window glass. Unlike the case of hanging, the mounting workability is good and the sheet is transparent, so it is not noticeable and the room is not darkened. Therefore, even after a resident moves in, it can be used for the purpose of shielding ultraviolet rays without being peeled off from the window glass as it is. Furthermore, it can utilize also as a protection sheet for the purpose of antifouling by sticking the said sheet | seat after cleaning of a window glass.

  In order to stick the said sheet | seat on a window glass, it needs to have adhesiveness. In order to have adhesiveness, an adhesive layer is laminated on one surface of the synthetic resin sheet, and the synthetic resin sheet itself has self-adhesive properties and has self-adhesive properties. When a sheet is used, an adhesive layer is unnecessary.

  Conventionally, it has been necessary to install a poster or a bag for the purpose of displaying or advertising that the property is vacant, etc., but printing an advertisement or advertising display as a printed layer on one side of the sheet. By doing so, it is possible to provide advertisements and advertising effects. In addition, the printed display as this printed layer is repeatedly formed with the same display pattern along the length direction of the synthetic resin sheet, so that no matter where it is cut according to the size of the window, advertising and advertising effects Is obtained.

  When the sheet is made translucent, it has a blinding effect for preventing the interior from being seen.

  Such vacant window sheets can be widely used for windows, glass doors, and the like of ordinary houses, apartments, condominiums, office buildings, store buildings, commercial facilities, public facilities, and other various buildings.

  Hereinafter, an embodiment of a vacant window sheet of the present invention will be described with reference to FIG.

  FIG. 1 shows a vacant window sheet 1, 2 is a synthetic resin sheet, and a printing layer 3 is provided on one surface of the sheet as required. Furthermore, an adhesive layer (not shown) is laminated on the sheet surface to be attached to the window glass, or a synthetic resin sheet having self-adhesiveness is used.

  The synthetic resin sheet 2 has excellent transparency such as a vinyl chloride resin, an olefin resin, a thermoplastic polyurethane resin, a polyester resin, an acrylic resin, etc. (hereinafter referred to as “sheet”). If it is, it will not be specifically limited.

  As the vinyl chloride resin used for the sheet 2, a vinyl chloride homopolymer, a copolymer of vinyl chloride and another monomer, or a blend of a vinyl chloride resin and another resin can be used. Examples of the monomer copolymerized with the vinyl chloride resin include vinyl acetate, ethylene, propylene, maleic acid ester, methyl methacrylate, methacrylic acid ester, acrylic acid ester, and higher vinyl ether. Other resins blended with the vinyl chloride resin include ethylene-vinyl acetate copolymer resin, acrylonitrile-butadiene-styrene copolymer resin, acrylonitrile-butadiene copolymer resin, polyurethane resin, chlorinated polyurethane resin, polymethacrylate resin, etc. It is done. Examples of the olefin resin include polyethylene resin, polypropylene resin, polybutadiene resin, ethylene-propylene copolymer resin, ethylene-1-butene copolymer resin, ethylene-vinyl acetate copolymer resin, ethylene-methyl acrylate copolymer resin, ethylene-methyl. Examples thereof include methacrylate copolymer resins. Said synthetic resin can also be used individually or in mixture of 2 or more types.

  Examples of the thermoplastic polyurethane resin include those condensed with a polyol such as diisocyanate and polyester, polycarbonate or polyether.

  Examples of the polyester resins include aliphatic polyester resins and aliphatic oxycarboxylic acid resins having an aliphatic and / or alicyclic diol unit and an aliphatic and / or alicyclic dicarboxylic acid unit as essential components. .

  Examples of the acrylic resin include poly (meth) acrylate methyl, acrylic acid alkyl ester-methyl methacrylate copolymer, (meth) acrylic acid-styrene copolymer, (meth) methyl acrylate-styrene copolymer, and the like. Can be mentioned.

  It is desirable to select an ultraviolet absorber to be blended in the sheet 2 that is excellent in heat resistance, has good compatibility with the resin, can be uniformly dispersed, and does not adversely affect the resin. As the ultraviolet absorber, various known applications such as benzophenone, benzotriazole, hindered amine, oxalic acid, salicylate, cyanoacrylate, and the like can be used. Benzoyl-4-hydroxy-2-methoxyphenyl) methane, 2,2'-4,4'-tetrahydroxy-benzophenone, 2,2'-dihydroxy-4-4'-dimethoxy-benzophenone, 2,4-di -T-Butylphenyl-3 ', 5'-di-t-butyl-4'-hydroxybenzoate, 2- (3', 5'-diterariamil-2'-hydroxyphenyl) benzotriazole, 2 (2 ' -Hydroxy-3'-t-butyl-5'-methylphenyl) -5-chlorobenzotriazole, 2 (2'-high Roxy-3 ', 5'-di-t-butylphenyl) -5-chlorobenzotriazole, 2 (2'-hydroxy-3', 5'-di-t-butylphenyl) benzotriazole, 2-ethoxy-2 '-Ethyloxazac acid bisanilide, 2,4-di-tert-butylphenyl-3', 5'-di-tert-butyl-4'-hydroxybenzoate, bis (2,2,6,6-tetramethyl -4-piperidyl) sebacate, dimethyl succinate 1- (2-hydroxyethyl) -4-hydroxy-2,2,6,6-tetramethylpiperidine polycondensate, phenyl salicylate, ethyl-2-cyano-3, Examples include 3-diphenyl acrylate.

  The ultraviolet absorber is not particularly limited, and may be used alone or in combination of two or more in some cases. The content of the ultraviolet absorber in the layer is preferably 0.1 to 6.0 parts by weight per resin, and if it is within this range, the ultraviolet shielding rate can be 90% or more. It is possible to prevent discoloration deterioration due to ultraviolet rays. On the other hand, when the content is lower than the above range, the ultraviolet shielding rate is less than 90%, and it is not possible to sufficiently prevent deterioration of discoloration due to ultraviolet rays such as interior and tatami mats. However, there are problems in terms of formability and cost.

  Moreover, the said sheet | seat 2 mix | blends various additives, such as a plasticizer, a stabilizer, tackifier, and a coloring agent, as needed, and is formed into a sheet by the calendar method, the extrusion method, etc. About the kind and addition amount of an additive, what is necessary is just to add required quantity of a required kind of additive, and what is necessary is just to select suitably according to the kind etc. of resin to be used. In addition, when using a coloring agent, it is preferable to add in the range which does not impair the transparency of a sheet | seat.

  The thickness of the sheet 2 is preferably 50 to 300 μm. If the thickness is less than 50 μm, the strength of the sheet and the workability of attaching are reduced. As a result, problems such as the sheet being easily peeled off and the sticking workability also deteriorated.

  In order to stick the said sheet | seat on a window glass, it needs to have adhesiveness. In order to have adhesiveness, for example, an adhesive layer may be laminated on a sheet surface to be attached to a window. Conventional adhesives can be used as the adhesive layer, for example, rubber solvent type adhesives, acrylic solvent type adhesives, silicone solvent type adhesives, urethane solvent type adhesives, vinyl solvent type adhesives, etc. If it is excellent in transparency, such as an adhesive and a hot-melt type adhesive, it will not specifically limit. As the acrylic solvent-based pressure-sensitive adhesive most used among the above-mentioned pressure-sensitive adhesives, ethyl acrylate, n-butyl acrylate, and the like can be used. Said adhesive can also be used individually or in mixture of 2 or more types.

  The adhesive layer preferably has an adhesive strength of about 0.015 to 20 N / 25 mm. Within this range, the adhesive layer has sufficient adhesive strength, and no trace of glue or the like remains when it is peeled off from the window glass. If it is less than this range, sufficient adhesive strength cannot be obtained. If this range is exceeded, marks such as glue remain when peeling from the window glass, and the film is torn when peeling, resulting in poor workability. Problems occur.

  Moreover, you may use what the sheet itself has self-adhesiveness other than laminating | stacking an adhesive layer on the sheet | seat surface of the side stuck on a window. In this case, the adhesive layer is unnecessary, and the adhesive strength is preferably about 0.015 to 20 N / 25 mm, as in the case of using the above adhesive layer. Within this range, the adhesive layer has sufficient adhesive strength, and the window glass. No trace of glue or the like remains when peeling from, but if it is less than this range, sufficient adhesive strength cannot be obtained, and if this range is exceeded, traces of glue or the like remain or peel off when peeling from the window glass In such a case, the film is torn and the workability is lowered.

  In order to have self-adhesiveness, a necessary amount of additives necessary for exhibiting self-adhesiveness may be added, and may be appropriately selected depending on the type of resin used, required self-adhesive performance, and the like.

  In addition, in the manufacturing stage, the sheet for vacant window of the present invention can be laminated with a release paper to improve the workability for unfolding and the workability for sticking.

  When the sheet is pasted on the window glass, the sheet is transparent and does not stand out, and the room does not become dark. Therefore, the sheet can be used as it is for the purpose of shielding ultraviolet rays without being peeled off from the window glass. Furthermore, it can utilize also as a protection sheet for the purpose of antifouling by sticking a sheet | seat after cleaning of a window glass.

  The sheet 2 can be provided with a printing layer 3 on one side of the sheet in order to provide advertising and advertising effects. In the case of a sheet provided with the above-mentioned adhesive layer, for example, it is provided on the sheet surface on which the adhesive layer is laminated on the side to be attached to the window glass, or on the sheet surface on which the adhesive layer is not laminated, opposite to the side to be attached to the window glass May be. In addition, in the case of a sheet having self-adhesiveness without providing the above-mentioned adhesive layer, for example, it is provided on the sheet surface on the side pasted on the window glass, or on the sheet surface opposite to the side pasted on the window glass Also good. In addition, when providing in the sheet | seat surface opposite to the side stuck on a window glass etc., it is assumed that a sheet | seat is stuck on a window glass and you may print a printing display with a reverse character. Further, a sheet provided with the printing layer 3 may be bonded to the sheet 2.

  For example, it can be displayed that a vacant room is inviting a tenant, and a manager's contact information can be printed. For printing on the sheet, oil-based ink, water-based ink, alcohol-based ink, solvent-based ink, or the like can be used, and is appropriately selected depending on the type of resin used for the sheet. As the printing method, a commonly used printing method can be used, and a textile printing method, an inkjet printing method, an offset printing method, a screen printing method, a gravure printing method, a flexographic printing method and the like are adopted.

  At this time, it is preferable that the printed display as the print layer is repeatedly formed in the same display pattern along the length direction of the sheet so that an advertisement or advertising effect can be obtained no matter where the sheet 2 is cut. .

  In the present invention, because of the blindfold effect, the sheet 2 can be translucently provided so that the inside of the room cannot be seen. Such a translucent sheet is particularly suitable for use in stores. As a method for making the sheet translucent, a commonly used method can be employed. For example, a method of reducing the transparent visibility by applying a satin finish using an emboss or adding a colorant is employed. .

  In addition, the sheet 2 may be a single layer or may be composed of a plurality of layers. When a plurality of layers are formed, for example, the sheet 2 and the printed layer 3 are laminated on the printed layer 3 or the like. Is done. In the case of a plurality of layers, the resin of each layer may be the same type or different types. By using a plurality of layers, the durability of the sheet 2 is improved and the printing layer 3 is protected. For example, on the printing layer 3 provided on the sheet surface opposite to the side to be attached to the window glass When a sheet is laminated as a surface protective layer, the printed layer 3 can be protected.

  Next, examples and comparative examples of the present invention will be described in detail, but the present invention is not limited thereto. In addition, the ultraviolet-ray shielding rate in an Example and a comparative example was measured according to JISK6714 (1977).
