The present invention relates to a sheet for preventing illegal advertisements and a method of manufacturing the same, and more particularly, to prevent illegal advertisements from being attached to various road facilities such as street lights, telephone poles, traffic signal control boxes, etc. And to a method for producing the same.

As is well known, various advertisements such as stickers are attached to the facilities installed on the road such as street lamps and telephone poles installed on the road for various advertisements for pedestrians. Therefore, it is the main culprit that undermines the aesthetics of the city, and even though such illegal advertisements are strictly prohibited by law, they are publicly practiced and cannot be cracked down.

Therefore, in the past, a number of people were hired to remove the attached advertisements as part of the public works project at the city hall or the ward office, but illegal advertisements used more powerful adhesives.

Therefore, the removal work becomes more difficult, such as the need to provide a separate appropriate tool to scrape the illegal advertisements. As a result, more manpower is consumed and more labor costs are consumed to remove the illegal advertisements. There was a vicious circle where the ad was attached to the removed spot.

Therefore, in recent years, an illegal advertisement attachment prevention sheet is attached to a street lamp or a telephone pole to prevent the advertisement itself from being attached, and this example is illustrated in FIG. 1.

As can be seen from the above, the conventional illegal advertisement attachment prevention sheet forms a print layer 101 on which a picture or a pattern is printed on the substrate 100, as shown in FIG. The adhesion preventing layer 102 coated with silicone or an oil having an anti-sticking property is formed so as not to stick.

Such an anti-adhesion sheet is installed in streetlights, telephone poles and other installed facilities to attach the advertisement to it, but can not adhere to the advertisement by the anti-stick layer 102, but is left in the sunlight or moisture penetration, Repeated partial shrinkage and expansion due to temperature variation from -20 ° C to 40 ° C according to the change of the season causes problems such as the adhesion preventing layer 102 being lifted or dropped from the printing layer 101.

In addition, Korean Patent Application No. 2001-70898 (name of the invention: a method for forming an anti-adhesion anti-adhesion surface and its anti-adhesion pad, hereinafter referred to as 'quoting invention') is disclosed, which is shown in FIG. .

As can be seen from this, the cited invention is a substrate layer 105 formed of a fabric paper cloth having a predetermined width, the paint layer 106 is coated with liquid paint on the surface of the substrate layer 105, the paint The sand or carborundum layer 107 sprayed before being hardened and adhered by the adhesive force of the paint to be embossed, and the adhered sand or carborundum layer 107 are coated with silicon or an oil agent 108 so that the surface is embossed. Consisting of a surface coating layer 109.

As such, the cited invention is attached to sand or carborundum and embossed with silicone or emulsion, so that the effective surface of the surface of the advertisement can be attached to a very limited area. It is difficult to uniformize the arrangement intervals at the time, and thus there is a disadvantage in that the silicone or the oil agent is not coated with a uniform thickness and a uniform shape, so that the adhesion preventing performance is partially weakened. This tricky, long-lasting liquid paint hardens, resulting in poor work efficiency and poor productivity, and high surface strength and coarse sand or carborundum exposed to the risk of injury from pedestrians. There was a problem such as.

In addition, since the conventional cited invention is sand or carborundum opaque, it is difficult to contribute to the beautification of the road environment because it represents a simple pattern by the liquid paint.

The object of the present invention devised to solve the above problems is to uniformly etch the ultraviolet curable resin, coated with a silicone or an oil on the upper surface thereof, and then the temperature change in the outdoors after the installation of the anti-adhesive sheet, humidity, solar Even if exposed to light for a long time, it is possible to maintain a uniform and stable anti-sticking performance, and to provide an illegal ad-proof sticking prevention sheet safe to use and a method of manufacturing the same.

In order to achieve the above object, the present invention is an anti-adhesion sheet having a printed layer formed by printing a picture or pattern on a substrate, the fine recesses and protrusions at uniform intervals, uniform standards on the printed layer After forming, and curing it, to form an anti-adhesion layer coated with silicon or an emulsion, and cured it proposes an illegal advertisement prevention sheet and a method of manufacturing the same.

In this way, the present invention, even if the anti-sticking layer is stretched due to temperature change, moisture infiltration, etc. as a long time after installation, because the stretch rate according to the temperature change is almost interlocked by the ultraviolet curable resin, partly twisted or separated While the phenomenon is suppressed and the anti-stick layer by silicone or oil coating is not eliminated, it is possible to maintain long-lasting anti-sticking performance, while excellent anti-sticking performance is achieved by reducing the effective area of ad attachment by the recesses and protrusions. Will have.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

4 illustrates a method of manufacturing an illegal advertisements prevention sheet according to the present invention. As can be seen from this, the present invention first provides a substrate of a tough material for attaching to various road facilities. It is advantageous to use a synthetic resin mainly for such a substrate, since the shrinkage rate and the expansion rate due to the temperature change need to be the same level as those of the protruding layer formed by the printing layer and the myriad fine protrusions and the anti-sticking layer.

The printing layer 15 is formed by displaying various guide characters, symbols, figures, etc. using various printing techniques such as screen printing on the substrate. Subsequently, the present invention should form a protrusion layer 20 made of a protrusion made of fine synthetic resin on the printing layer 15, and various printing techniques such as etching may be used for this purpose. For example, when the mesh is covered on the printing layer 15, the ultraviolet curable resin is applied on the mesh with a roller or the like, the surface is scraped off, and only the ultraviolet curable resin remains. , Unsaturated polyester with excellent UV curability, excellent adhesion, polyfunctional acrylate with low shrinkage, epoxy acryl or epoxy acrylate with excellent UV curability, scratch resistance Urethane acrylate (Urethane Acrylate) with excellent scratchability and adhesion can be optionally used. After performing the etching step such that the ultraviolet curable resin remains on the print layer 15 in this way, if the first drying step of irradiating and curing the light of the ultraviolet light lamp is carried out, the finely cured indentation portion ( 30 and only the protrusion layer 20 which is a protrusion remains. In this state, by coating a silicone or an emulsion thereon to form an anti-stick layer 25, and performing a second drying step of drying and curing by an ultraviolet lamp, the illegal advertisement according to the present invention as shown in FIG. Production of the anti-stick sheet is completed.

In this series of manufacturing process, the present invention forms a protrusion layer by etching, and then irradiates with UV lamp to cure rapidly, and then forms an anti-stick layer with silicone and emulsion coating, and then irradiates with UV lamp to cure. Therefore, as in the case of the cited invention, there is no time lost to wait for paint curing, so that manufacturing can be performed quickly.

The illegal advertisement prevention sheet according to the present invention obtained as described above becomes a surface having a fine concavo-convex shape by the protruding portion layer 20.

If you cut the attachment sheet of the present invention to the size to be installed in the installation facilities, such as street lamps, telephone poles, and attach it, the construction is completed, the person who tries to attach illegal advertisements in such a state to attach the advertising paper In this case, the adhesive is released from the surface of the anti-sticking layer 25 to prevent the attachment of the handbill. Furthermore, an effective contact area capable of attaching illegal advertisements to the surface of the anti-sticking layer 25 by the top of the protruding layer 20 is provided. It is so narrow that virtually no attachment is possible.

In particular, the present invention is inevitable to a considerable extent as the temperature is changed from about -20 ℃ to 40 ℃ in accordance with the change of the season in this state, and in addition, the occurrence of partial distortion due to the penetration of sunlight and moisture is inevitable. Do. In this state, the present invention not only has the same stretching ratio due to the temperature change of the substrate, the concave portion 30, the protruding portion layer 20, and the adhesion preventing layer 25, but also the printing layer 15 and the adhesion preventing layer 25. ) Is firmly engaged by the concave portion 30 and the protrusion layer 20, even if the phenomenon is pushed to one side as shown in Figure 6 can be suppressed the phenomenon that the adhesion preventing layer 25 is separated In addition, as shown in FIG. 7, even when the surface of the diarrhea adhesion prevention layer 25 is partially dropped, the remaining adhesion prevention layer 25 filled in the concave portion 30 between the protrusion and the protrusion of the protrusion layer 20. Since the anti-sticking performance is maintained as it is, it is possible to stably maintain the anti-sticking performance even under adverse conditions as described above. In addition, the anti-sticking layer 25 according to the present invention manufactured in this way is because the lower protrusion layer 20 is made of ultraviolet curable resin instead of sand, and may cause injury to pedestrians due to sharpness or roughness such as sand. There is no, so it is safe.

In addition, according to the present invention, the projection layer 20 formed on the print layer 15 is made of a transparent resin, and various patterns, pictures, characters, etc. of the print layer 15 are made to be transparent. By being represented externally through 25), it is possible to provide a road beaconing function such as a beautification function of a street or a caution.

In the present invention as described above, since the anti-stick layer is filled in the concave portions 30 between the protrusions, and is combined with a plurality of protrusions, the layer separation phenomenon is suppressed even when total or partial stretching occurs due to temperature and humidity changes. In addition, even when the anti-adhesion layer is partially dropped, it is possible to provide stable and long anti-adhesion performance by the silicone or emulsion coating filled in the concave portion 30 which is the valley between the protrusion and the protrusion of the protrusion layer 20. It is effective to be.

In addition, the present invention by using the UV curable resin in the protrusions, it is possible to quickly dry to improve the productivity, as well as the material of the protrusions is a synthetic resin rather than inorganic, there is no fear of injury to passers-by even if the surface is damaged and exposed. It works.
