Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a blind blade that can be replaced at any time to remove discoloration and stains that occur over time.

(Prior art) Conventionally, blind blades have been made of a single layer of cloth, metal plates, plastic plates, etc., and when exposed to direct sunlight, the color fades over time, and when used with accumulated dirt, the final The reality is that they are being discarded and replaced with new ones.

(Problem that the invention aims to solve) If the blind blades can be updated at any time with simple operations, not only will the comfortable appearance of the blind be maintained at all times, but fading or staining of the blind blades will immediately lead to the need to dispose of or renew the blind itself. It also has great economic merit as it does not lead to problems.

(Means for Solving the Problems) The present invention aims to solve the problems of the above-mentioned prior art, and the blind blade 1 has a layer structure consisting of a release agent layer 2, a base material 4, and an adhesive layer 3 in this order. The adhesive sheets 7 are sequentially laminated.

A wide variety of materials can be used for the base material 4. Examples include paper, synthetic film, synthetic fiber paper, woven fabric, nonwoven fabric, plastic film, metal foil, cellophane, and the like. The base material may be selected from any thickness depending on the desired thickness of the blind blades, the number of layers to be laminated, the combination of various base materials, etc.

When paper is used as the base material, art paper, coated paper, cast coated paper, etc. can be used, but it is preferable to use neutral paper from the viewpoint of fading resistance and durability. Further, a pigment coating layer 5 may be provided between the base material and the release agent layer.

The adhesive layer 3 includes generally known acrylic emulsion type, acrylic solvent type, acrylic hot melt type, acryl radiation curing type, rubber emulsion type, rubber radiation curing type, silicone solvent type, and urethane type. It is formed by applying a solvent-based adhesive or the like.

On the other hand, the release agent layer 2 is generally coated with or impregnated with a silicone compound or a fluorine compound, and the like is appropriately selected and used. In addition to imparting releasability, the release agent has a water-repellent effect, so that it will not be affected by rainwater, and dirt can be easily removed.

In the present invention, if the adhesive sheets 7 to be laminated to form the blind blades are individually colored or printed with various patterns, a more decorative appearance can be enjoyed. ,
By laminating a combination of adhesive sheets with different base materials, you can enjoy a different appearance each time you peel off the adhesive sheets and renew the blind blades.

If the blind blades lack sufficient stiffness for use, a metal plate, plastic plate, stiff paper, or the like may be laminated as the reinforcing substrate 6 on the bottom layer.

(Function) Since the blind blade of the present invention is laminated with the adhesive sheet 7, which has the release agent layer 2, the base material 4, and the adhesive layer 3 in this order, it is possible to prevent stains that occur over time from becoming noticeable. By peeling off the adhesive sheet, you can always maintain a clean and comfortable appearance. Furthermore, due to the effect of the release agent, dirt and the like can be easily wiped off without being affected by rainwater.

Examples of the present invention will be described below, but it goes without saying that the present invention is not limited only to these examples.

(Example) The drawings illustrate one embodiment of the invention.

Figure 1 shows the thickness of the base material used in this invention.

This is a partial cross-sectional view of a blind blade formed by laminating the following in order so that the adhesive side 3 and the release agent side 2 are in contact with each other, and laminating a 1 mm thick plastic plate as a reinforcing substrate 6 on the bottom layer.

Figure 2 shows the thickness of the base material used in this invention.
Adhesive sheets using 20 μm aluminum foil 4b and adhesive sheets using 100 μm thick colored cast coated paper 4c as base materials are alternately laminated, and a 1 mm thick plastic plate is laminated as the reinforcing substrate 6 on the bottom layer. FIG.

(Effects) By peeling off the adhesive sheet that makes up the blind blades at any time, a clean and comfortable appearance can be maintained at all times, and the uneconomical cost of discarding or renewing blinds due to fading or staining can be eliminated.
