Description

Phosphorescent adhesive design sheet and design sheet manufacturing method {STICK TYPE DESIGN SHEET HAVING STORED LIGHT AND MANUFACTURING METHOD THTEREOF}

The present invention relates to a photoluminescent adhesive design sheet and a method of manufacturing a design sheet in which a photoluminescent pigment such as fluorescence or phosphorescence is applied and adhered to a road surface.

In general, on the surface of concrete and asphalt pavements applied to pedestrian paths or roads (hereinafter referred to as'road surfaces'), road information necessary for driving, including direction guidance signs and speed limit signs, and roads such as crosswalks, school signs, and bus lane signs Information on the situation, and on the surfaces of elastic pavements applied to sports, amusement facilities or pedestrian paths, and waterproof pavements applied to interior flooring materials such as buildings or rooftop waterproofing flooring are marked with bicycle road markings.

These road surface sheets are in front of the school according to the provisions of Article 4 of the Road Traffic Act, Article 3, Paragraph 2 of the Enforcement Regulation of the Act, and Article 11, Paragraph 2 of the Road Traffic Act Or it includes road seats in front of a kindergarten (school zone), an elderly protection area (silver-zone), and a youth curfew area (red-zone) under the Youth Protection Act.

In general, the road surface sheet is molded with heat-resistant synthetic resin such as polyurethane, and then a reflective sheet or reflector having a glass bead property is attached to one side or the front side so that the light of the vehicle running at night is reflected, thereby enhancing the visibility of the driver.

However, since the reflective film of the conventional road sheet shines only by light, if it is installed in a dark place where the light of the vehicle's headlight does not shine, or in a dark place without streetlights or work lights, pedestrians or drivers do not visually recognize the road sheet. There was a problem that the visual guidance function could not be displayed due to the failure.

In order to solve the above problems, a road sheet or a guide plate is manufactured using fluorescent and phosphorescent (hereinafter, referred to as'phosphorescent') urethane of Patent No. 280232 invented. The conventional road sheet or guide plate produced in this way is self-illuminating at night without a separate lighting means after being luminous with daylight or vehicle light, and through this, pedestrians as well as drivers can visually display the road sheet or guide board. It can be recognized as.

On the other hand, unlike general information boards such as traffic signs, a road surface sheet that directly attaches to the road surface to display characters or characters has a design sheet function for designing the road surface itself in addition to the general traffic information display function. Therefore, the road sheet functioning as a design sheet achieved a relatively detailed and complex shape design.

To this end, conventionally, a road sheet having a design sheet function was produced by a full-color printing method by ink jet, and was applied to the road sheet by an adhesive method.

However, since the surface of the conventional printing-type road sheet is easily worn by passing vehicles and pedestrians, the application life is short, and it cannot be installed on a road surface that a vehicle passes through, such as a roadway, and there is a limitation in that a phosphorescent pigment cannot be applied.

In order to solve this problem, conventionally, a technique has been proposed in which a plurality of color pieces are assembled according to a design, such as a puzzle, and then fused to the road surface using a hot melt method. Unlike the adhesive type, the fusion type is integrated by melting the road surface sheet on the road surface, so it has an advantage that it can be installed on the roadway because it has relatively excellent wear resistance compared to the conventional adhesive type.

However, the conventional fusion road sheet had a problem that the work was cumbersome and the construction process was long because various color pieces had to be combined in the field, and because the road sheet must be heated for road fusion, it is not possible to apply a photoluminescent pigment that is easily denatured by heat. There was a limit.

In the end, it was required to develop a road surface sheet with a design sheet function that has excellent abrasion resistance, has a photoluminescent function, and enables detailed design expression.

Accordingly, the present invention is to solve the above problems, as a problem to solve the provision of a luminous adhesive design sheet and a design sheet manufacturing method that can express a detailed design, have a luminous function, and can be adhesively applied on a road surface in a short period of time. do.

There will be. Since the present invention can apply various changes and have various forms, specific embodiments will be illustrated in the drawings and described in detail in the text. However, this is not intended to limit the present invention to a specific disclosed form, and it should be understood to include all changes, equivalents, and substitutes included in the spirit and scope of the present invention. The terms used in the present application are only used to describe specific embodiments, and are not intended to limit the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view showing the configuration of a design sheet according to the present invention.

Referring to FIG. 1, the road sheet (hereinafter referred to as'design sheet') of the present invention is completed by combining layers 20 and 60 of different colors like a puzzle. Therefore, the design sheet of this embodiment has clear color classification, no color bleeding by running vehicles and pedestrians, and extends the life of attachment to the road surface due to excellent abrasion resistance.

In addition, in the design sheet of the present invention, a phosphorescent pigment is applied to main parts such as letters and characters, so that the visibility of vehicle drivers and pedestrians with respect to the main parts is increased even at night. To this end, in the design sheet of this embodiment, a paint layer 20 forming a background is first produced, and a designated section corresponding to the main part is cut in the paint layer 20 to form a void (S), and void (S) A photoluminescent pigment is injected to the photoluminescent layer 60.

As a result, in the design sheet of the present embodiment, a traffic sign having a phosphorescent function is clearly displayed even at night based on the painting layer 20, and through this, a vehicle driver or a pedestrian can safely pass on the corresponding road.

FIG. 2 is a cross-sectional view showing a state in which an adhesive layer and a release paper are formed on a base layer and a paint layer of a design sheet according to the present invention, and FIG. 3 is a perspective view schematically showing a coupling structure of a tube composed of the adhesive and a fluid resin. .

1 to 3, the method of manufacturing a design sheet of the present invention includes a first step of forming a painting layer 20 by applying a painting pigment on the upper surface of the base layer 10 made of polyester; A mixture of the adhesive 31 is applied to the lower surface of the base layer 10 so that the porous tube 32 of the iron powder mixed resin component containing the flowable resin 33 of the flowable polyurethane gel coat component is located at the bottom and adhered. A second step of forming a layer 30; It includes; a third step of coating the release paper 40 on the lower surface of the adhesive layer 30 to finish.

The base layer 10 forms the supporting body of the design sheet. Therefore, the base layer 10 of the design sheet is preferably made of a resin material having rigidity for maintaining shape and ensuring durability. In addition, since the design sheet is installed on a road surface with a lot of moisture change in the field, it is preferable that it is a resin material that is not hygroscopic and has a waterproof function. In addition, since the design sheet is transported and installed on site, it is preferable that it is made of a resin material having flexibility for easy portability. Therefore, the base layer 10 of the present invention is made of a polyester material to ensure rigidity, waterproofness, and flexibility, and has a thickness greater than or equal to the reference value to enable formation of the void (S).

Since the base layer 10 is a supporting body of the design sheet, it is cut according to the designed design.

When the base layer 10 is completed, a paint layer 20 is formed by applying a paint pigment on the upper surface of the base layer 10. The color of the paint pigment is selected according to the design of the design sheet and forms a material that does not dissolve in water or oil. In the manufacturing method of the present embodiment, the primary color is achieved by uniformly applying a color pigment to the entire upper surface of the base layer 10 in the same color.

When the base layer 10 and the paint layer 20 are completed, the adhesive 31 is applied to the lower surface of the base layer 10 to form the adhesive layer 30. Since the design sheet of the present invention is installed in concrete or sidewalks having a relatively rough surface, the design of the surface is deformed when the design sheet is attached to the road surface. Therefore, before installing the design sheet on the road surface, be sure to perform pre-processes such as cleaning the surface of the road surface and applying and drying primers to minimize the deformation of the design sheet. However, even after the preliminary process, since the road surface does not form a perfect flat plate, problems such as design deformation, damage, and moisture inflow of the design sheet cannot be completely solved.

In order to solve this problem, the design sheet of the present invention constitutes a porous tube 32 in which the flowable resin 33 is accommodated in the adhesive layer 30. The fluid resin 33 is a resin material having a relatively high fluidity, and flows to the road surface through the adhesive 31 together with a hit by a rubber hammer for road surface adhesion and flows into the groove of the road surface, and the groove is combined with the hardener. Cured in Of course, the adhesive adheres to the road surface during the hitting process to attach the design sheet to the road surface. The flowable resin 33 of the present invention constitutes a polyurethane gel coat resin component having relatively excellent flowability compared to the adhesive 33 and is accommodated in the porous tube 32.

The porous tube 32 constitutes a hollow for accommodating the flowable resin 33, and has porosity so that the porous tube 32 can be pulverized when hit. At this time, since the porous tube 32 is manufactured in a fine size, the flowable resin 33 accommodated in the porous tube 32 is preserved without leakage from the porous tube 32 by its own surface tension.

The porous tube 32 containing the flowable resin 33 is mixed with the adhesive 31. At this time, the adhesive layer 30 of the present invention is configured such that the porous tube 32 accommodating the fluid resin 33 is positioned under the adhesive 31, so that when the adhesive layer 30 adheres to the road surface, the fluid resin ( The porous tube 32 containing 33) preferentially abuts the road surface.

On the other hand, the porous tube 32 forms an iron powder mixed resin to be pulverized when hit. At this time, since the iron powder has a large specific gravity, it is introduced into the road surface by its own weight along the flow of the flowable resin 33 during pulverization. In addition, the porous tube 32 of the present embodiment is a mixed resin for binding the iron powder to the porous tube 32, and an acrylic resin having relatively low strength and hardness is applied.

For reference, for the road surface installation of the design sheet of the present invention, a curing agent is first applied to the primer surface after the primer application and drying process, and the design sheet is installed. Accordingly, the curing agent preferentially contacts the porous tube 32 accommodating the flowable resin 33 on the surface of the adhesive layer 30. This will be explained again below.

When the adhesive layer 30 is formed, a release paper 40 is coated on the lower surface of the adhesive layer 30 to finish. The reason for coating the release paper 40 and the coating technique are already known techniques, so the description thereof will be omitted here.

4 is a cross-sectional view showing the configuration of the aluminum layer and partial cutting of the design sheet according to the present invention, and FIG. 5 is a cross-sectional view showing the configuration of the photoluminescent layer and the photocatalyst layer of the design sheet according to the present invention.

1 and 4 to 5, the design sheet manufacturing method of the present invention forms a void (S) by cutting a designated section in the painting layer 20. The cutting of the painting layer 20 is performed manually or by a dedicated device depending on the design, and the painting layer 20 disappears and the base layer 10 is exposed in the formation section of the void (S). In the cutting process, a part of the upper surface of the base layer 10 may be cut as shown in FIG. 4, or only a part of the painted layer 20 may be precisely cut.

When the voids S are formed through the cutting process, the aluminum layer 50 is formed by coating the edges of the voids S with aluminum. The aluminum layer 50 performs a boundary function so that the photoluminescent pigment heated for the gel state does not discolor the general pigment of the paint layer 20 or damage the cutting line, and increases the light reflectance of the photoluminescent pigment.

The aluminum layer 50 of this embodiment is an adhesive resin in which aluminum powder is mixed, and is cured using natural curing or a curing agent after application.

When the aluminum layer 50 is cured, a photoluminescent pigment is injected into the voids S to form the photoluminescent layer 60. Phosphorescent pigments are known components that emit light by being modified by daytime or light irradiated from a vehicle, and can be made of various organic dyes such as ZnS and aluminum silicate, as well as YAG-Ce and Y2O3-EU. In addition, a synthetic resin that binds the components of the photoluminescent pigment is mixed, and the synthetic resin of the photoluminescent layer 60 of the present embodiment is preferably of high luminance in order to increase the scattering degree of light, and, if necessary, is preferably a material having excellent flexibility and transparency. Do.

For reference, the synthetic resin component of the photoluminescent layer 60 may be urethane having relatively high flexibility but relatively low transparency, and may be PET having relatively high transparency but relatively low flexibility. The synthetic resin component of the photoluminescent layer 60 is selected according to the installation environment of the design sheet.

A photocatalyst layer 70 is formed by applying a photocatalyst on the upper surface of the photoluminescent layer 60.

As is well known, since the photocatalyst is a material that promotes a chemical reaction by receiving light, it is applied to the photoluminescent layer 60 to accelerate the chemical reaction of the photoluminescent pigment by photoluminescence and light emission. As a result, the phosphorescent layer 60 emits strong light with high luminance, so that a driver or a pedestrian can clearly recognize the design sheet even at night and confirm the display expressed by the phosphorescent layer 60. For reference, as the photocatalyst, at least one selected from among oxide semiconductors such as TiO2, ZnO, WO3, and SnO2 is made of synthetic resin to form the photocatalyst layer 70.

6 is a cross-sectional view showing a configuration of a coating layer and a ventilation line of a design sheet according to the present invention, and FIG. 7 is a cross-sectional view showing a configuration of a protective film of the design sheet according to the present invention.

6 to 7, in the method of manufacturing a design sheet of the present invention, a transparent coating agent 80 is integrally applied to the upper surface of the photocatalyst layer 70 and the upper surface of the painting layer 20.

The transparent coating agent 80 covers the photocatalyst layer 70 and the paint layer 20 divided by the aluminum layer 50 as a boundary, and fixes and protects it, and prevents moisture inflow into the boundary section. The reason for coating the transparent coating agent 80 and the coating technique are already known techniques, and thus description thereof will be omitted here.

When the application and curing process of the transparent coating agent 80 is completed, the perforation pin R1 penetrating to the base layer 10 presses the upper surface of the transparent coating agent 80 with a protruding pressure roller R and is pulled out. Therefore, in the design sheet passing through the pressing roller (R), the through hole (H) is formed by the perforated pin (R1) during the pressing process, and the through hole (H) formed in this way is generated between the road surface and the design sheet during the road surface bonding process. To exhaust air or moisture, etc. during the hitting process.

For reference, it is preferable that the perforation pin (R) of the pressure roller (R) is of a length that does not extend to the adhesive 30, and the method of manufacturing the design sheet of the present invention is the curing of each layer (10, 20, 60, 70). When is completed, the pressing and drilling process of the pressing roller (R) proceeds.

When the pressing and punching process of the pressing roller R is completed, the upper surface of the coating agent 80 is covered with a protective film 90.

The protective film 90, together with the release paper 40, prevents damage to the design sheet due to external force and other environmental changes, and blocks the inflow of external air or moisture through the through hole H. The reason for coating the protective film 90 and the coating technique are already known techniques, and thus description thereof will be omitted here.

8 and 9 are cross-sectional views sequentially showing a road surface installation of a design sheet according to the present invention.

8 to 9, before installing the design sheet of the present invention on the road surface (C), the surface of the road surface (C) is cleaned and heated to a certain temperature or higher.

When the road surface (C) is heated to a certain temperature, a primer is first applied to the surface and dried.

When drying of the primer is complete, apply a curing agent to the primer surface, align the design sheet to the installation position of the road surface (C) with the release paper 40 attached, and adhere the release paper 40 as shown in Fig. 8(a). Separate from layer 30. In the process of separating the release paper 40, be careful not to allow air to flow between the road surface (C) and the design sheet.

When the release paper 40 is all separated, the adhesive layer 30 contacts the road surface C through temporary compression as shown in FIG. 8(b), and through this, the design sheet is accurately disposed at the installation position of the road surface C. .

When the arrangement of the design sheet is completed, the protective film 90 on the upper surface of the design sheet is peeled off, as shown in FIG. 9, and the porous tube 32 configured under the adhesive layer 30 by hitting the design sheet with equipment such as a rubber hammer. Impact In this process, the porous tube 32 made of iron powder is pulverized, and the flowable resin 33 accommodated in the porous tube 32 removes fragments of the porous tube 32 having a relatively large specific gravity compared to the adhesive 31 on the road surface (C ) To fill the groove as shown in FIG. 9. That is, in the porous tube 32, which first comes into contact with the road surface C from the lower part of the adhesive layer 30, the debris formed by the blow moves along the flowable resin 33 and flows into the groove of the road surface C.

On the other hand, the curing agent applied to the surface of the road surface (C) first cures and fixes the flowable resin 33 filled by flowing the fragments of the porous tube 32 into the groove, and secondarily, the adhesive of the adhesive layer 30 (31) is hardened and adhered to the road surface (C).

For reference, since the striking process that proceeds when installing the design sheet takes a relatively long time, it is preferable that the curing of the curing agent be sufficiently delayed in consideration of the time point at which all crushing of the porous tube 32 is completed.

In the detailed description of the present invention described above, it has been described with reference to preferred embodiments of the present invention, but those skilled in the art or those of ordinary skill in the relevant technical field, the spirit of the present invention described in the claims to be described later And it will be understood that various modifications and changes can be made to the present invention within a range not departing from the technical field.
