Description

Anti-graffiti prevention and adhesion prevention of promotional materials using adhesive and night light reflection device

The present invention relates to prevention of oily graffiti, prevention of adhesion of promotional materials using adhesives, and night light reflecting devices, and more particularly, various facilities installed for public purposes such as street lights, telephone poles, electric power boxes, subway walls, or personal building walls. It can prevent oily graffiti, graffiti graffiti (magic spray and oily magic) on the back, and prevent illegal advertisements from being attached without permission, and prevents oily graffiti at night or in rainy weather. It relates to an anti-sticking device and a night light reflecting device.

Accidents due to the unauthorized crossing of roads are increasing nationwide every year, and this may be one of the reasons for the lack of awareness of pedestrian order and the prevention of traffic accident prevention. In addition, traffic accidents in children around elementary schools are also often due to driver's carelessness and traffic jams caused by illegal parking and stopping in areas where traffic and roads are prohibited. Therefore, traffic accident prevention information can be installed to prevent traffic accidents caused by unauthorized crossings, traffic accidents caused by traffic jams caused by traffic jams due to traffic jams, etc. It will increase citizens' awareness.

However, even if these publicity or warning publicity materials are installed in public facilities on the road, the city streets are deteriorated by personal graffiti, graffiti graffiti, and graffiti graffiti. Public service publicity materials are obscured by acts such as sticking paper advertisements with glue, stickers, foam tape, or scribbling phone numbers with meteor magic. There is a problem that the aesthetics of the city is hindered.

In addition, recently, a QR code is printed on public information materials, and there is a problem in that the QR code is damaged or the function is deteriorated due to inadvertent attachment of a promotional graffiti, graffiti graffiti, etc., or personal advertisement paper advertisement. In addition, if the government that manages these behaviors uses a sharp spatula knife to remove graffiti and promotional materials, the surface of existing facilities may be damaged and rust may occur.In the process of removing graffiti and promotional materials by applying common paint, the QR code It may be damaged or the function may be deteriorated.

In particular, the pillars of the building, the walls, the front door of the apartment, the traffic light flasher box, the street light control box, and the power distribution box BOX are located on the easiest road that most of the public can access. Or Graffiti graffiti, or the use of pressure-sensitive adhesive paper advertising is attached. As such, graffiti or graffiti attached to the surface of various personal or public facilities indiscriminately impairs the aesthetic, and if this condition is left unattended, moral insensitivity such as "warning of the Broken Window Theory" This leads to unauthorized dumping of garbage or damage to personal and public property, and furthermore, it can be a serious social problem as it can lead to light and heavy crimes.

In addition, the visibility of road facilities, such as road guide poles and speed limit indicator poles installed on the road during night driving, is very important to the driver who relies on the headlights of the car and the white, so improving visibility of road facilities is a very important task.

Government or local governments use sharp iron hera to illegally remove promotional and phone number graffiti, graffiti graffiti, or adhesive-based promotional paper advertisements as a means of personal publicity, but publicity-purpose promotional materials and roads If the surface of the facility is damaged and severe, rust occurs, and paint is applied to remove oily graffiti.

In order to prevent the attachment of promotional materials such as conventional advertisements, a high-corrosion-resistant metal support cover (Korea Patent No. 10-0566947), while triangular protrusions are continuously formed on the front, the triangular protrusions are molded into an embossed form and insulated when combined with street light poles on the back. Although a protective cover of a street light pole having a space portion having a function (Korean Registered Patent 10-0952082), a coating composition comprising stone powder, acrylic resin, polyvinyl acetic acid, and water (Korean Registered Patent 10-1412870) has been reported, It is difficult to protect promotional materials for public purposes against acts such as graffiti of publicity and telephone numbers or graffiti graffiti with Yooseong Magic, and at the same time, no reports of night light reflection function have been reported.

Accordingly, the present inventor can easily wipe the graffiti magical or graffiti graffiti on public facilities such as walls, telephone poles, street lights, and traffic lights with a general wet cloth to improve the unique facility maintenance function and to promote the surface or public interest of facilities. At the same time as the adhesive strength on the print is reduced, the adhesive component does not remain even when the advertising paper is attached, and the illegal advertising paper can be easily removed without mechanical help such as a scraper, and visibility is secured by light reflection at night or in rain. We developed a preventable oily graffiti, prevent adhesion of promotional materials using adhesives, and a night light reflector.

The object of the present invention is a synthetic resin material soft film layer, such as PE or PVC, which has an advertisement printed on its surface and has an insulating function, flame retardancy, tensile strength, or non-absorption function according to external rain; A coating layer capable of forming fine irregularities or protrusions on one side of the soft film layer or reflecting light at night; An adhesive layer having excellent adhesion to the other side of the soft film layer; And it is to provide a night light reflecting device and prevention of adhesion to the promotional material using a pressure-sensitive adhesive and a pressure-sensitive adhesive, and optionally a contaminant prevention block.

Another object of the present invention comprises the steps of sequentially forming the soft film layer, the coating layer, the adhesive layer, and optionally the anti-contamination block, preventing the adhesion of promotional materials using oil-based graffiti and adhesive, and a method of manufacturing a night light reflecting device.

Although the role of preventing the adhesive by the unevenness is the same, it is different from the glass beads forming the fine unevenness or protrusion in that it serves as a light reflection.

Retroreflection refers to a phenomenon in which a mirror surface is formed by refracting inside a glass bead while light is projected onto glass beads, thereby reflecting and maintaining the same angle as the incident angle of light. It is shown.

Since the retroreflective beads have a round bead shape, the stress is the same regardless of the force in any direction, and the shape is the strongest in all directions.

In addition, since the material of the retroreflective beads is glass, it is in a chemically stable state, and thus has excellent water resistance, alkali resistance, acid resistance, chemical resistance, solvent and heat resistance.
