The advertising apparatus using the retractable frame according to the present invention configured as described above includes an image sheet for POP advertisement and an LED display for transmitting text messages, so that advertisement efficiency is significantly improved, and an image sheet and an LED display board can be installed. This retractable type has the advantage that it is easy to install, replace, and repair the image sheet and the LED display board.

On the other hand, the image sheet 600 used in the advertisement device using the retractable frame according to the present invention contains copper powder (copper powder) having excellent antibacterial magnetic flux to increase antibacterial persistence, and in particular, increase contamination resistance and internal adhesion. It is preferable to use a sheet having remarkably improved hygiene by preventing it from being easily attached.

To this end, the image sheet 600 includes a first pellet forming step; A second pellet forming step containing zinc; Mixing the first and second pellets and sheet raw materials; Melt molding step; is manufactured as an eco-friendly sheet having an antibacterial function including.

At this time, the first pellet forming step is a step of mixing copper powder and PVC sol in a weight ratio of 3:7 and then extrusion-molding to form a pellet. Here, the copper powder is prepared by copper vapor condensation, and the copper vapor condensation method is a method of making copper vapor at a high temperature and ejecting it at a low temperature to condense the copper vapor. Say. This copper powder is a powder having a particle size of almost nano-sized, and has a very strong antibacterial activity as traditionally known. In particular, since copper is ductile, it is very advantageous to maintain its flexible properties when manufactured as a film.

In the second pellet forming step, zinc oxide powder having a particle size of 40 nm and PVC sol are mixed in a weight ratio of 4:6 and then extruded to form a pellet. Here, the zinc oxide powder is a powder containing a zinc component having natural antibacterial properties, which has been used since ancient times for bronze alloys and brass alloys, and has been reported to be very effective in sterilizing staphylococcus aureus and pneumococcus.

As described above, the reason why the two components are separately pelletized in the present invention is to maximize the dispersion in a homogeneous state and to maximize the antibacterial effect through quantification of the blending ratio. Since this is formed in a sheet form through calendaring later, it cannot exhibit a uniform antibacterial effect unless uniform dispersion is secured. In other words, if the powder is simply mixed and then calendered after quantitatively mixing the powder, a phenomenon in which the powder is localized or agglomerated on one side occurs is to solve this problem.

In addition, the first and second pellet and sheet raw material mixing steps are a step of mixing raw materials for sheet molding, and the first pellet and the second pellet, the PVC sol, and the octamethylcyclotetrasiloxane are 2:2:4:2. It is a step of mixing by weight ratio. At this time, the octamethylcyclotetrasiloxane is a waterproof organic material and is added to enhance the anti-fingerprint property by increasing the contact angle by increasing the contact angle while increasing the water repellency.

In other words, the components of the fingerprint and the stain are attached by the force between the molecules active between the surface and the octamethylcyclotetrasiloxane is contained, the stain adhesion is weakened and the stain component is not easily adhered, so that the fingerprint does not remain. It contributes very effectively to suppressing and blocking infectiousness by not easily adhering to contaminants such as

In addition, the melt molding step is a step of forming a film by forming the mixed raw material in a known sheet manufacturing method.

Here, the present invention may further add 20 parts by weight of ommochrome to 100 parts by weight of the film raw material for film forming in the first and second pellet and sheet raw material mixing steps.

The ommochrome is a biological pigment group generated by the breakdown of tryptophan, an amino acid, and provides natural antiseptic functions and natural antiviral properties. This induces an effective defense mechanism while being harmless to the human body, and helps to maintain antibacterial persistence as it has a characteristic that remains on the surface of the film for a long time. In particular, the ommochrome has been reported to be effective in inhibiting and killing the growth of microorganisms when added to fungi such as Listeria monocytogenes, Salmonella enterica, Staphylococcus aureus, Haemophilus influenza, and Candida albicans.

In addition, in the present invention, a step in which the sheet manufactured after the melt molding step is immersed in an immersion liquid and then dried and then wound in a roll form may be further performed.The solution pan (PAN) containing the immersion liquid in a continuous line It may be carried out so that it is automatically immersed while gradually passing by, and dried through a drying furnace after running through the room temperature drying section after immersion. At this time, the reason for running the room temperature drying section for a certain distance is to have a time for stabilizing the immersion liquid, and then it may be configured to dry while passing very slowly through a drying furnace maintained at 30-40°C. Here, the immersion liquid consists of 40% by weight of rutin, 20% by weight of deoxypodophyllotoxin, 10% by weight of selenium, 10% by weight of rosin, and the remaining water-soluble urethane resin. In this case, Rutin is added to suppress inflammation during skin contact, and Deoxypodophyllotoxin is a substance reported to have anti-allergic and anti-asthma properties. It is added to suppress the occurrence of allergies. In addition, selenium is added to prevent surface oxidation at the adhesive interface and to perform a sterilization function, rosin is added to adjust viscosity and planarize the immersion surface, and water-soluble urethane resin is a base resin to increase adhesion.

As a result of testing the antimicrobial properties according to such a composition, it was confirmed that antimicrobial properties were expressed against Listeria monocytogenes, Salmonella enterica, Staphylococcus aureus, Haemophilus influenza, Candida albicans, pneumococcus, fungi, etc. In addition, as a result of measuring the coefficient of friction on the surface of the sheet in order to confirm the anti-fingerprint, stain resistance and prevention of foreign matter adhesion, it was confirmed that it has a very low coefficient of friction as 0.06. This is a value such that the surface slip resistance is very low, so that fingerprints are not adhered to, and dust is not adhered, and the pollution prevention characteristics are very good. Through this, it was confirmed that the transmission of pathogens can be prevented and the antibacterial persistence is also maintained.

As described above, although the present invention has been illustrated and described in connection with specific embodiments, it is known in the art that various modifications and changes are possible without departing from the spirit and scope of the invention indicated by the claims. Anyone who grows up will be easily aware of it.
