Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to a bulletin board, in which posters, etc. are pasted with strong adhesive, etc., and the posters, etc. can be easily peeled off after the required period of time has passed. This is about a bulletin board.

[Technical background of the invention and its problems] Conventionally, posters of candidates are strongly attached to bulletin boards, etc. that announce candidates in elections, etc., using an adhesive such as glue. Currently, even if one tries to remove the bulletin board 4, it is not possible to remove it completely, and for this reason, the bulletin board cannot be used for the next election and is discarded after each election. Therefore, there was a major problem in that the cost of materials and labor increased, resulting in a huge amount of money being spent for each election.

[Purpose of the invention] Therefore, in view of the above-mentioned points, this invention makes it possible to easily peel off posters, etc. after the necessary period has passed, even if the posters, etc. are strongly pasted, thereby making it possible to reuse them. It was devised for this purpose.

[Summary of the invention] In order to achieve the above-mentioned purpose, this invention applies a release coating layer that can be forcibly peeled off directly on the surface of the plate material after an appropriate surface treatment or without surface treatment. It is said that it was formed by coating.

[Embodiments of the invention] Hereinafter, embodiments of the invention will be described with reference to the drawings.

That is, the reference numeral 1 shown in the figure is a board made of plywood of an appropriate size, which is the material of the bulletin board B.

Then, as shown in FIG. 1, the surface of this plate material 1 is subjected to surface treatment by applying a paint that also serves as a filler to form a coating layer 2. Furthermore, after drying, a strippable paint is applied to the surface of the coating layer 2 so that the coating film can be forcibly peeled off by hand or with a knife to form a peelable coating layer 3.

That is, the poster 4 is adhered to the surface of the release coating layer 3 with an adhesive such as glue (not shown),
When peeling off the poster 4 after the required period has passed, as shown in FIG. A cut is made in the stretched release coating layer 3 with a knife 6 so that the corner end 5 can be forcibly peeled off at once in the direction of peeling. In other words, the poster 4, which had been strongly attached with an adhesive, can now be easily peeled off along with the release coating layer 3, and the poster 4 on the bulletin board B can now be completely peeled off. Further, after the poster 4 is completely peeled off from the surface of the bulletin board B, the strippable paint is applied to the surface again to form a release coating layer 3, so that the bulletin board B can be reused.

In addition, strippable paints include chlorinated rubber paints, cellulose derivative paints, vinyl emulsion types,
There are emulsion types of synthetic rubber paints, etc., but the adhesive strength is such that they do not peel off due to abrasion during transportation or installation of bulletin board B, but can be easily peeled off by forced peeling as described above. For example, any type of material may be used. In order to have the above-mentioned adhesive strength, in addition to selecting a variety of strippable paints, the adhesive strength also changes depending on the baking conditions after the paint is applied, so the baking conditions must be set appropriately to remove the paint. What is necessary is to form the covering layer 3.

On the other hand, as shown in FIG.
In that case, since the plate material 1 is made of plywood, its surface is rough and there are countless small holes (not shown), so peeling is less likely than in the case where the coating layer 2 is formed. Since the coating layer 3 is difficult to peel off, the peelable coating layer 3 is formed by selecting a strippable paint with a correspondingly weak adhesion, or by adjusting and setting the baking conditions as appropriate to facilitate peeling.

If the material of the board 1 is appropriately selected and the surface is smooth, the strippable paint used to form the coating layer 2 can be used to apply the peelable coating layer 3 directly onto the board 1. All you have to do is form.

As for the size of bulletin board B, we manufacture standard products with appropriate standards, and when creating a small bulletin board B, we install only one standard product, and when creating a large bulletin board B, we install multiple standard products in parallel. If the bulletin board B is installed in the area, it can be formed in any size, and the bulletin board B can be provided at low cost by mass producing the standard product.

[Effects of the invention] As explained above, this invention applies and forms a forcibly removable release coating layer 3 on the surface of the plate material 1 after appropriate surface treatment or directly without surface treatment. As a result, even if the poster 4 is strongly attached to the surface of the release coating layer 3, the entire release coating layer 3 can be easily peeled off. Since it can be completely peeled off, it can be used any number of times by forming the peelable coating layer 3 again and using it, and it is possible to effectively use plate materials that were conventionally disposed of. In addition, if it is standardized and mass-produced, it can be provided at a low cost, and in conjunction with the above-mentioned reuse, it is especially suitable for use in election announcements, and can significantly reduce election costs, etc. etc., it has practically beneficial effects.
