Description

Metal plate to prevent illegal advertisement promotional materials

The present invention relates to a metal plate for preventing the attachment of illegal advertisements and promotional materials, and more particularly, it prevents the attachment of illegal advertisements attached to road structures or minimizes the adhesion force even when illegal advertisements are attached, and has durability, weather resistance and pollution resistance. It relates to a metal plate for preventing the attachment of illegal advertisements and promotional materials that can be improved and can be recycled to minimize environmental pollution.

In general, various road structures such as telephone poles, street lights, and traffic lights are installed on the road, and the road structures are used as a good place to advertise in the present age where advertisements are popular enough to be called the age of advertisements. Advertisements such as various stickers and posters are adhered to the pillars of such structures with adhesives such as glue, and the appearance of the pillars is damaged by the adhered posters or advertisements, and the aesthetics of the street are also disturbed. In order to prevent this phenomenon, in general, anti-adhesion plates are installed on various road structures such as telephone poles, street lights, and traffic lights.

A conventional anti-adhesive plate includes a sheet and a band.

The sheet is to be installed on the road structure, is generally formed in a rectangular shape and is composed of an elastic material such as rubber or PVC. In addition, the sheet is formed with a plurality of projections to prevent adhering to the surface of the sheet. Since these protrusions do not provide a sufficient area for the advertisement to be attached, the advertisement cannot be attached to the anti-adhesion plate.

In addition, the band is used to prevent the mounted sheet from falling to the ground and to fix its position on the road structure after the seat is mounted while wrapping the perimeter of the road structure. wrapped around and mounted

In order to install such a conventional sheet while wrapping the perimeter of the roadway structure, first, in a state where the plate is wrapped around the roadway structure, one end of the plate is brought into contact with the other end of the plate, and then the band is installed while wrapping the periphery of the plate elements. , Ensure that the plate installed on the road structure is fixed around the road structure and does not fall to the ground.

As an example of this, Korean Patent Laid-Open Publication No. 2006-0085610 discloses that a relatively thick concave-convex shape is made on the surface of a synthetic rubber plate of a certain thickness, an electric pole is covered with a certain width, and the upper and lower parts of the uneven plate are formed. Disclosed is an illegal advertisement blocking sheet fixed with a steel band.

However, although the blocking sheet has an effect of preventing the adhesion of advertisements, it is not easy to use because it has a structure that is difficult to construct as well as to make the appearance of the pole look clunky. In addition, the blocking sheet has a problem in that it is difficult to use for a long time because a certain level of durability, weather resistance, and stain resistance are not added.

Therefore, an object of the present invention is to block the attachment of various types of illegal advertisements to the outer wall of road structures, to be applied regardless of the type and shape of the adherend, and to improve the aesthetics of the city. It is to provide a metal plate for preventing adhesion of promotional materials.

In order to achieve the object of the present invention described above, in one embodiment of the present invention, a bottom plate formed of a metal, and a binder layer provided on the bottom plate and particles provided in the binder layer in a state protruding to the outside. It provides a metal plate for preventing attachment of illegal advertisements and promotional materials including a protrusion layer.

In addition, in order to achieve the object of the present invention, in another embodiment of the present invention, a bottom plate that is in contact with the surface of the road structure and formed of pure aluminum or Al-Mg-based alloy, and a coating film for coloring on the top of the bottom plate A pretreatment layer to form, a printed layer for forming a pattern on the upper surface of the pretreatment layer, and a binder layer provided on the printed layer and a protruding layer composed of particles provided in the binder layer in a state protruding to the outside, , The binder layer, 30 to 42% by weight of acrylic resin, 5 to 9% by weight of polymethacrylic acid S, 36 to 55% by weight of ester solvent, 2.5 to 3.5% by weight of xylene, 2.5 to 3.5% by weight of aromatic solvent, poly 100 parts by weight of an acrylic polyol resin composed of 2.5 to 3.5% by weight of an ester siloxane copolymer, 1.5 to 2.5% by weight of a silicone antifoaming agent, and 40 to 60% by weight of polyisocyanate and 40 to 60% by weight of toluene 15 to 25 of an isocyanate-based compound It is composed of a two-component paint reacted with parts by weight, and the particles are composed of polymethacrylic acid ester.

According to the present invention, it is possible to block the adhesion of various types of advertisements, promotional materials and other foreign substances, and can be easily removed even after being attached, and it is possible to keep the environmental aesthetics clean by not leaving an adhesion mark after removal.

And since the present invention uses relatively inexpensive aluminum or aluminum alloy instead of using an expensive synthetic resin that satisfies a certain level of durability, weather resistance, and stain resistance, the production cost is reduced and productivity and economical benefits can be obtained at the same time.

In addition, the present invention can form a printed layer that can display various advertisements, and unlike the conventional sheet using a synthetic resin as a main material, a metal material is used as the main material, so that a part of the paint in the process of forming the print layer is used. not absorbed Accordingly, it is possible to reduce the amount of paint, which is an environmental pollutant.

In addition, since the present invention uses a metal material that is easy to recycle instead of a synthetic resin such as PE or PET, which is difficult to recycle, it is possible to minimize environmental pollution.
