Problems solved by technology

[0004] However, since the supports of road facilities have straight sides or round columns, and the walls of buildings or buildings also have flat surfaces, paper-made advertising materials or attachments such as stickers and posters are easily stick to them, making it difficult to monitor and prevent these buildups
In addition, once pasted, advertising materials or attachments such as

Example Embodiment

[0084] Example 1

[0085] The release structure with glass beads and protrusions adhered to the surface of the polyurethane resin was prepared by the following method: 1kg of polyurethane resin was respectively coated on 25cm×15cm steel, aluminum, resin frame, transparent resin plate, glass and concrete, Make the thickness all 1 mm, spray 800 g of glass beads with an average diameter of 0.1 mm before the polyurethane resin hardens, and harden them. Specifically, the resin frame to which the release structure is applied is shown in FIGS. 3 and 4.

[0086] The adhesive tape with the adhesive thereon was adhered to one side of each of the steel, aluminum, resin frame, transparent resin plate, glass, and concrete with the release structure prepared above. As a result, the tape does not stick to any of steel, aluminum, resin frame, transparent resin plate, glass, and concrete. In addition, graphite is used to contaminate steel, aluminum, resin frames, transparent resin plates, glass, a...

Example Embodiment

[0088] Example 2

[0089] Except for using glass beads with an average diameter of 50 μm, the same method as in Example 1 was used to prepare a release structure.

[0090] For the steel, aluminum, resin frame, transparent resin plate, glass, and concrete on which the release structure was formed, the tape adhesion test was performed using the same method as in Example 1. As a result, the tape did not adhere to any of steel, aluminum, resin frame, transparent resin plate, glass, and concrete, and the tape could be easily removed even when a great pressure was applied during adhesion. Drop.

Example Embodiment

[0091] Example 3

[0092] 1kg of polyurethane resin and 1kg of glass powder with an average diameter of 200 mesh and a specific gravity of 2.54 were uniformly mixed, and the mixture was coated on steel, aluminum, resin frame, transparent resin plate, glass and concrete, and then passed through the implementation and Example 1. Prepare the release structure in the same way as in. The tape adhesion test was performed using the same method as in Example 1, and the results showed that the anti-adhesion effect was the same as in Example 1.

[0093] In addition, external pressure was applied to the release structures prepared in Example 1 and Example 3 to check whether the glass beads fell off. As a result, compared with the release structure of Example 1 in which no glass powder was used, the release structure of Example 3 to which glass powder was added had a more excellent ability to bond with glass beads.

Abstract

The present invention provides an anti-adhesion mechanism and a method of producing it and more particularly, it provides an anti-adhesion mechanism comprising a structure body, a resin binder layer comprising a resin binder coated on all or part of the surface of the structure body and a bead layer comprising a plurality of beads bond to the upper side of the coated resin binder layer and being salient outside, and a method of producing an anti-adhesion mechanism comprising coating a resin binder on the surface to be coated, spraying beads on the upper portion of the resin binder before the coated resin binder is hardened and hardening them to form bead protrusions. The anti-adhesion mechanism prepared in accordance with the invention can prevent the adhesion of attachments such as stickers, posters and dusts to the coated surface and easily remove the attachments even though they are adhered, can be readily formed and can improve such properties as weather resistance, contamination resistance, scratch resistance, chemical resistance and impact resistance of the surfaces coated therewith.

Description

technical field [0001] The present invention relates to an anti-adhesion structure (anti-adhesion mechanism) and a method for producing the same, and more particularly, to a structure capable of preventing adhesion of stickers, posters, dust, etc., to the surface of the following objects , and an anti-adhesive structure that can easily remove attachments or dust even if they have adhered, including road facilities such as telephone poles, traffic lights, street lamps, traffic signs, and control boxes Or their supports, guardrails, road signs, internal and external frames, walls of buildings or structures, lamps or lamps, the anti-adhesive structure can make dust adhere as little as possible to places where a large amount of dirt has adhered The surface of the structure in the environment with dust, and they can be easily removed, the anti-adhesive structure can be easily formed, and can improve the surface coated with it such as weather resistance, pollution resistance, prope...
