Description

The present invention relates to a picture blind and a method for manufacturing the same.
More particularly, the present invention relates to a blind having a durable arbitrary pattern formed on the surface of the blind and a method of manufacturing the same.

(Conventional technology and its problems) Conventionally, a glass window is provided with a blind for the purpose of avoiding direct sunlight and preventing see-through from outside.

In many cases, these blinds can be wound up and rewinded by connecting aluminum sheets having a width of several cm with a string. Also, these blinds are often painted with a suitable paint. Although these blinds have a significant effect on the indoor atmosphere, only a monotonous colored material is present up to the present time, and there is no known type provided with various patterns other than a single color.

This is considered to be due to the difficulty in printing with good adhesion to aluminum and the difficulty in printing with good weather resistance due to exposure to direct sunlight.

Accordingly, an object of the present invention is to solve the above-mentioned various problems of the prior art, and to provide an aluminum blind provided with a beautiful pattern and a method of manufacturing the same.

(Means for Solving the Problems) The above object is achieved by the present invention described below.

That is, in the present invention, a polyester layer, an adhesive layer, a pattern layer and a protective layer as necessary are laminated on at least one surface of the narrow aluminum sheet, and the adhesive layer, the pattern layer and the protective layer are all provided. A picture blind characterized by being mainly composed of an acrylic resin, and a transfer foil slightly wider than the aluminum sheet on at least the polyester surface of a narrow aluminum sheet having a polyester layer formed on at least one surface. ,
A method for producing a pictured blind, characterized in that the polymer is passed between a pair of heated rubber rolls and a pattern mainly composed of an acrylic resin is transferred to a polyester layer.

(Action) By transferring the pattern to the surface of the aluminum sheet via the polyester layer as the primer layer, a pattern with excellent adhesiveness is transferred.

In transferring a pattern, a transfer foil slightly wider than the above-mentioned aluminum sheet is overlaid, and the polymer is passed between a pair of heated rubber rolls, thereby enabling uniform transfer without displacement.

Preferred Embodiment Next, the present invention will be described in more detail with reference to the accompanying drawings, which show a preferred embodiment schematically.

The picture blind of the present invention has a polyester layer 2, an adhesive layer 3, a picture layer 4 and a polyester layer 2 on at least one surface of a narrow aluminum sheet 1 as shown schematically in FIG. Is characterized in that a protective layer (peeling layer) 5 is laminated according to.

The aluminum sheet 1 is an aluminum sheet having a width of about 2 to 3 cm, a length of about 1 to several meters and a thickness of about 0.1 to 0.3 mm, and is a material constituting a conventionally known aluminum blind.

In the present invention, the polyester layer 2 is laminated on both sides of the aluminum sheet. Before cutting the aluminum sheet into an appropriate width, the polyester layer is subjected to an appropriate surface treatment such as sanding, brushing, and degreasing,
It can be formed by a well-known coating method or the like, and a preferable thickness is about 3 to 15 μm.

The adhesive layer 3, the picture layer 4, and the protective layer 5 adhered to the polyester layer 2 are transferred from a transfer foil.

In the transfer foil used above, a protective layer (release layer) 5, a picture layer 4 and an adhesive layer 3, which are provided as necessary, are sequentially formed on one surface of the base sheet 10 as shown in FIG. It becomes.

The substrate sheet 10 used for the transfer foil may be any conventionally known substrate sheet, for example, a polyester film such as polyethylene terephthalate, a polyethylene terephthalate / isophthalate copolymer, and polybutylene terephthalate is preferable, and particularly preferable is Is 10-10
It is a biaxially stretched polyethylene terephthalate film having a thickness of about 0 μm.

The protective layer 5 provided on the surface of the base sheet 10 as needed is unnecessary when the peelability between the base sheet 10 and the picture layer 4 is good. It is preferable that the resin layer is formed from a resin excellent in quality and is transferred together with the picture layer at the same time as the transfer, and is formed so as to become a protective layer of the picture layer after the transfer.

The protective layer 5 is formed of a material mainly composed of an acrylic resin having excellent transparency and various durability, and is preferably formed to a thickness of, for example, about 0.5 to 2 μm.

The picture layer 4 formed on the protective layer 5 can be formed by performing arbitrary picture printing using a normal gravure ink comprising a pigment, a binder and an organic solvent. The pattern of these pattern layers is not particularly limited, and may be a solid pattern to various patterns, and may be a full-color pattern composed of several colors of ink. The thickness of such a pattern layer is 1 to 5 μm.
m is preferable. The binder used for the picture layer is mainly composed of an acrylic resin having excellent weather resistance.

The adhesive layer 3 provided on the picture layer is mainly made of an acrylic resin having excellent weather resistance. The thickness of the adhesive layer is preferably about 1 to 5 microns.

In each of the above layers, the protective layer 5 and the adhesive layer 3 are coated with a coating solution in which the respective resins are dissolved, for example, by a gravure coating method, a gravure reverse coating method, a reverse roll coating method, an offset gravure coating method, or the like. It can be formed by drying.

Each layer may be added with an extender such as silica, alumina, or calcium carbonate for the purpose of improving foil breakage during transfer, or other various additives such as an antistatic agent, a water repellent, and an oil repellent. , An ultraviolet absorber, a stabilizer, a matting agent, and the like.

The picture blind using the transfer foil is preferably manufactured as shown in FIG.

As shown schematically in FIG. 3, an aluminum sheet 1 provided with a polyester layer 2 is passed between a pair of rubber rolls 6, 6 'heated and pressed to an appropriate temperature. At this time, the transfer foil 20 is inserted between the rolls 6, 6 'and the aluminum sheet 1. By superimposing the transfer foil on both sides of the aluminum sheet as shown, both sides are simultaneously painted.

The transfer foil 20 used at this time is slightly wider than the width of the narrow aluminum sheet 1, for example, about 5 to 20%, so that the movement of the aluminum sheet 1 and the transfer foil 20 causes some disturbance. However, it is possible to transfer a pattern to the entire surface of the aluminum sheet.

Further, the rolls 6 and 6 'used above need to be rubber rolls, and in the case of a conventional metal roll, there is a problem that the transfer foil 20 is cut off due to a pressure fluctuation at the time of transfer, which is not preferable.

The heating temperature of the roll is about 150 to 230 ° C, and the pressure is 3 to
Preferably, the transfer speed is about 15 kg / mm.

(Effect) According to the present invention as described above, a pattern with excellent adhesiveness is transferred by transferring the pattern to the surface of the aluminum sheet via the polyester layer.

In transferring a pattern, a transfer foil slightly wider than the above-mentioned aluminum sheet is overlaid, and the polymer is passed between a pair of heated rubber rolls, thereby enabling uniform transfer without displacement.

(Examples) Next, the present invention will be described more specifically with reference to examples and comparative examples.

Example 1 An acrylic resin-based gravure ink medium (manufactured by Showa Ink Co., Ltd.) was applied to the surface of a polyethylene terephthalate film (X-45, manufactured by Toray Industries, Inc., thickness: 25 μm) and dried to form a protective layer having a thickness of 1 μm. Formed. On its surface, 80% by weight of polymethyl methacrylate resin and vinyl chloride /
A pattern was printed with a gravure ink containing a binder composed of 20% by weight of a vinyl acetate resin. Further, a solution of a polybutyl methacrylate resin (Tg 50 ° C.) was applied to the surface and dried to form an adhesive layer having a thickness of 3 μm to obtain a transfer foil used in the present invention.

Next, using a continuous foil stamping machine as shown in FIG. 3, a polyester layer was laminated on both sides, and the width was 25 mm, the length was 200 cm and the thickness was 0.15 mm.
The aluminum sheet is inserted between rubber rolls (temperature 200 ° C), and the above-mentioned transfer foil having a width of 30 mm is arranged on both sides thereof,
Transfer was performed at a pressure between the rolls of 10 kg / 10 mm and a transfer speed of 5 m / min to obtain an aluminum sheet having both sides painted. When a cellophane tape peel test was performed on this sheet,
The pattern did not peel at all.

Comparative Example 1 A painted aluminum sheet of a comparative example was obtained in the same manner as in Example 1 except that an aluminum sheet having no polyester layer was used. The picture was easily peeled off in the cellophane tape peeling test of this sheet.
