Description

Multi-Laminated Print for the Concrete and Method for Preparing the Same}

The present invention draws a reflection lane in which incident light and reflected light are retroreflected in the same direction on a road paved with asphalt or concrete, and multi-layer printing is performed on a concrete curved concave-convex wall surface. The characteristic of multilayer printing is that printing is possible in a short time because several functional layers including a transfer function are manufactured in a multilayer in accordance with a use in advance, and the printing exhibits a function that cannot be performed conventionally.

Reflective lanes provided for the purpose of the present invention has the purpose of protecting the driver's safety on rainy days and nights, and another function has a function to conveniently erase the lane to be printed on the road by printing the same asphalt photo. (Type lighter wipes like a ribbon). And another object of the present invention is to print the surface to the curved wall of the concave-convex surface.

Korean Patent Publication No. 87-1051 proposed a method of drawing a lane by thermal transfer on a pavement of asphalt and concrete. This technique applies the conventional thermal transfer method to the concrete, where the adherend is mainly used for plastic, and there is no consideration of irregularities on the surface of the concrete, and the problem of adhesive is particularly high. Thermoplastic adhesives used in this technology are problematic in terms of adhesion and strength, and even though they are adhered to by mistake, the inherent properties of thermoplastics are so weak that they can be easily worn or damaged on automobile wheels.

Japanese Laid-Open Patent No. 07060737 is a technology for transfer printing on concrete, which is more advanced than the technique introduced in Korean Patent Publication No. 87-1051 in that an epoxy-cement dough is used as an adhesive instead of a thermoplastic adhesive. Is considered. Epoxy, polyester, acrylic, polyurethane, and fluororesin-cement dough adhesives used in this technology are not specifically designated as dry or room temperature cure, but these adhesives require time to dry or cure at room temperature, and during curing Bubbles are generated between the concrete surface and the transfer sheet, and there is a problem in that transfer is not performed because the bubbles are not adhered to the bubble sites. Moreover, in the case where the unevenness of the concrete surface is severe, the problem of adhesion occurs more seriously. For this reason, the construction method of filling the uneven portion of the concrete surface with adhesive-cement dough was selected, but this may cause construction hassles, but it may be possible to construct a small area, but it is difficult to be commercialized in a large area. The price is too high.

The current reflective lane paint is done by dropping glass bead particles on the road. These problems can be seen that, firstly, technically uniform application is difficult, and secondly, glass bead particles are easily exposed to the outside and fall off the vehicle wheels.

Other transfer patents are reported to improve some of the layers of the transfer paper. For example, Japanese Patent Publication No. 06220384 relates to the composition of the transfer oil ink for raw concrete, US Patent No. 4,536,434 and the like relates to the manufacture of a release agent, Japanese Patent Publication No. 06183034 and the like relates to the manufacture of sublimation ink. Korean Patent Publication No. 88-13697, etc., relates to a method of transferring to ceramic tiles and iron plates, and World Integrated Patent WO 89-04889, etc., relates to transferring to ceramics such as glass, and Japanese Patent Publication No. 05327200. Is related to soldering in the manufacture of printed circuit boards, and much of the transfer technology is used for electronic functional products.

In the present invention, in consideration of these problems, the DuPont-based high-faron-based adhesive is also used as an adhesive called second generation adhesive (second generation adhesive) that is instantaneously cured only by the phase contact that does not need to mix the main agent and the curing agent. As a conventional commercially available adhesive, a polyurethane adhesive and a 2-cyanoacrylate instant adhesive were used as the adhesive agent capable of reacting with a two-component water-soluble epoxy adhesive and reacting with the water-soluble adhesive. These reaction mechanisms were solved by replacing the adhesive used as the concept of a relative adhesive by the reaction with water in the water-soluble epoxy adhesive and the adhesive having the characteristics of the instantaneous thermoplastic-temperature-curable type. It provides a reflection function that can be done. In the present invention, in order to solve the problem of irregularities of the concrete surface, the above problems were solved by using the transfer sheet as a heat shrink film.

Therefore, the above-described problems and characteristics of the reflective lane will be described in detail. FIG. 1 shows a longitudinal cross-sectional view of the multilayered printed body of the reflective lane, and the structure of FIG. 1 is a substrate 10, a release layer 20, and a UV coating layer 25. , The glass bead particle layer 26, the connection layer 27, and the printing layer 30 are used, and the adhesive layer is used to separate and construct the pavement 50. 2 shows the reflection mechanism of the glass bead particle layer 26.

The substrate 10 uses films of polyethylene terephthalate (PET), nylon, polypropylene, polyethylene, etc. having a thickness of 12 μm to 100 μm, of which PET is preferable.

Release agent 20 is a mixture of a wax or a surfactant, such as a vinyl compound is generally used, in the present invention, 100 parts by weight of polyvinyl acetate and 0.5 to 5 parts by weight of cetyltrimethyl ammonium bromide diluted in a mixed solution of acetone and methanol To 50 g / m 2 to 500 g / m 2.

UV coating 25 is used in the trade name Radrak (Korea / Korea Chemical Products) and serves as a high-strength surface protective layer and is applied 50 g / ㎡ ~ 500 g / ㎡.

The glass bead particle layer 26 used a high brightness optical fiber as a particle diameter of 45 μm to 860 μm (manufactured by Japan / Toshiba-Barotini Co., Ltd.), and may be applied as a solid powder or mixed with UV coating liquid. However, the concept of solid powder is not the same as the filler of paint. And when the glass bead particles 26 are overlapped as shown in FIG. 3, the reflection effect drops sharply and must be arranged in a row as shown in FIG. 2. Thus, the coating machine was manufactured and coated as shown in FIG. 4 for uniform coating. The distance between the head and the Laura of the glass bead particle emitter 63 was maintained at 1.5 times the diameter of the glass bead so that the glass bead particle layer 26 was arranged in one line. It was made.

4, the unwinding 61, the UV coating roller 62, the glass bead particle emitter 63, the primary UV hardener 64, the sprayer 65, the secondary UV hardener 66, It consisted of a cold 67.

The connection layer 27 used the brand name KR-920C (product made from Korea Republic of Korea Kukdo Chemical Co., Ltd.) as a one-component epoxy resin, and is coated with 10 g / m 2 to 120 g / m 2. The function of this compound layer has a function of increasing the adhesion between the UV coating liquid, the glass bead particles and the pigment layer 30. Since the UV coating solution hardly adheres to other compounds when fully cured, it is semi-cured in the primary UV curing device 64 as shown in FIG. 4, and the one-part epoxy resin 27 is very thin in a range of 10 g / m 2 to After coating about 120 g / m 2, it is a method of completely curing in the secondary UV curing machine 66.

Japan's Toshiba-Barotinini company, which is considerably ahead of the reflector, performs a method similar to the process of Figs. 4 to 25 as closed paint on the road. It is performed by dropping glass bead particles instantaneously after applying hot melt paint. These problems can be seen that, first, technically uniform application is difficult, and secondly, glass bead particles are easily exposed to the outside and fall off easily on the wheels of an automobile. However, if the UV coating on the exposed glass bead particles in order to achieve the same effect as the present invention, the UV curing lamp should be sprinkled on the road while spraying the coating liquid again. Repeated work on the road like this will block traffic around it, and huge working hours will lead to construction costs, which will completely eliminate economic feasibility. The use of this method by the Toshiba-Barrotini company means that it has not escaped the paint concept. It is very difficult to produce reflective paint on the mechanism. This is because the pigment is buried in the glass beads particles and interferes with the function of the glass beads particles. This means that the paint phase and the glass bead phase must be separated, and chemical treatment is difficult to overcome this fundamental physical phenomenon. However, the present invention can solve the problem very easily because it is a printing concept, not a paint concept.

The ink layer 30 may be a pigment used in a conventional lane as white, yellow, or the like to represent a ground color, and may be mixed with fluorescent dyes, or may be a metal deposition that may exhibit the same color effect.

The adhesive layer 40 is the most important functional layer in all transfer bodies. In particular, when industrial materials such as glass, ceramics, tiles, iron sheets, asphalt, concrete, and the like are to be adhered, physical properties such as adhesion, durability, heat resistance, and abrasion resistance are directly related to merchandise. However, most of the conventional transcripts overestimated the transfer function, but in the multilayer printing of the present invention, it is regarded as only one functional layer among many functional layers. In the conventional transfer member, the case where the adhesive layer is attached in one sheet state is preferred. If the transfer body and the adhesive are integral, the usable adhesive adheres to the basic condition that it must be a liquid solid at the time of coating and a thermoplastic solid or tacky semisolid capable of re-adhesion after coating. In other words, no matter how good the adhesive is, such as a three-dimensional curable adhesive, there is a restriction that it cannot be used. For this reason, the present invention separated the transfer body and the adhesive. If the transfer body and the adhesive are separated, the form becomes a paper-cut form, but it may not be fashionable, but all kinds of adhesives can be used and no restrictions are followed.

Considering these conditions, we listed the conditions of the adhesive that can work on the road as follows.

1. Adhesion should take place within seconds.

2. The initial bond should be strong enough not to fall off the friction of the wheels.

3. Curing proceeds at room temperature within 24 hours continuously after initial adhesion.

4. It must be durable to withstand temperature changes and rain or moisture.

Recently developed and conventional adhesives that meet the above conditions are listed as follows:

1) Second Generation Adhesive (SGA), called the second-generation adhesive, is based on chlorosulfonated polyethylene (trade name Hyparon) and has very suitable conditions for road construction.

1. Adhesion takes place in seconds

2. The initial adhesion is very strong and the physical properties are good enough to last forever.

3. Conventional curable adhesives require a good mixing of the main agent and the hardener, but the hyparon-based adhesives do not need to be the same.

This adhesive is called one of the recently developed functional adhesives, first developed by DuPont in the United States in 1975, and sold under the trade name Hyparon-30 (available from the United States / Dupont) as a chlorsulfonated polyethylene compound. This adhesive is deposited on both sides of the adhesive to be separated by a main body (A) composed of a polymerization initiator of Hyparon-30, an acrylic monomer, and an oxide, and a main body (B) composed of a hyparon-30, an acrylic monomer and a reducing agent. It is a method of bonding together after applying to water and bonding them together. The reaction proceeds instantaneously when the two adhesives meet and is bonded together. Here, the polymerization initiator of (A) and the reducing agent of (B) may be replaced by various types of compounds. When the adhesive is used for the reflective lane of the road, the main material A is coated on the road with the spray 70 of FIG. 5 from 100 g / m 2 to 100 g / m 2, and the main material B is 100 g / m 2 on the multilayer printed material. What apply | coated -1000 g / m <2> by the coater 62 is in close contact with each other.

2) The instant thermoplastic-normal temperature curing type adhesive was selected by dissolving a solid adhesive in an organic solvent, coating it on a multilayered substrate, and adhering it to a road while applying hot air to the softening temperature of the adhesive at 120 ° C (instantaneous thermoplastic step). This work must be completed at least one minute long. Even after the adhesive is adhered to the road, it is continuously cured at room temperature for 24 hours (at room temperature curing step), and thus changes to solid properties. Epoxy adhesive was used as the adhesive suitable for the above conditions, and 100 parts by weight of the brand name YD-012 (manufactured by Korea / Kukdo Chemical Co., Ltd.) and 30 parts by weight of the polyamide-based curing agent product G-0930 (Zheom, Korea / Kukdo Chemical Co., Ltd.) were used. It was.

Polyurethane adhesive was used as another type of adhesive, and 100 parts by weight of the trade name U-500 (manufactured by Korea / Kukdo Chemical Co., Ltd.) and 5 parts by weight of UCX-877 (manufactured by Korea / Kukdo Chemical Co., Ltd.) were used. Figure 5 shows the structure of the construction device of the instantaneous thermoplastic-temperature-curing adhesive, unwinding 61, coating roller 62, winding (67), hot air heater 68, heat sealer 69, sprayer ( 70), (71) is the remaining film portion of the substrate after printing, and (72) is the printing portion where the transfer printing is completed.

Still another object of the present invention can be used as a reflective marker plate by printing on a steel plate instead of bonding the multilayer printed material used in the reflective lane to the road.

It is still another object of the present invention to prepare a multilayer printed product in which the release agent layer is removed from the multilayer printed material used for the reflective lane, and then apply a temporary fixing adhesive thereto, and then roll the rolled sheet by laminating it with a siliconized paper to reflect the reflective label. It was manufactured as a commodity as a tape.

Another object of the present invention is to print on the uneven curved surface of the concrete wall surface. If you find a difference between concrete roads and walls, you will simply find the difference between horizontal and vertical planes, but the requirements for use require very many differences. Considering the differences in use, the concrete walls only require aesthetic effects, while the road only needs to effectively represent the lane function. The structure of multilayer printed material used for concrete wall is almost the same as the structure of the reflective lane, only the glass bead particle layer is partially used, and the components of the adhesive are different and manufactured as follows.

The substrate 10 may be a PE, PP, PVC heat-shrink film of 12㎛ to 100㎛ thickness. Of these, the use of the PP heat extraction film is most preferred.

The release agent 20 is the same as that of the multilayer printed circuit for reflection lanes described above.

The UV coating 25 is the same as the above-mentioned multilayer printed circuit for reflection lanes.

The glass bead particle layer 26 is the same as the above-described multilayered printed circuit for the reflective lanes, but is partially used in parts such as letters.

Since the connection adhesive layer 27 is the same as the multilayered printed circuit for the above-mentioned reflection lanes, and has an aesthetic effect, it is required to have good light resistance, so that it is a light stabilizer under the trade name Tinuvin 292 (manufactured by Shivagai Germany) and UV absorber. Tinuvin 1130 (manufactured by Germany / Shibagai Corporation) was used in combination.

The ink layer 30 used pigments having excellent light resistance because most of the concrete structure is exposed to sunlight. Since red is very fading in the sun, gravure ink is made separately using kintriton (Germany / Shibagai Co., Ltd.). Yellow is red because it is weak in the sun after red, but also fades. Gravure inks were made separately using phosphorus pigments (manufactured by German / Shibagai Company). Other colors blue, white and black used the common commercial gravure ink.

The adhesive layer 40 is an important functional layer that influences all the physical properties of the product, such as in the reflective lanes of the road, and also provides important conditions that determine the construction method. Since it is difficult to perform thermal fusion on the curved concave-convex concrete wall surface, the room temperature hardening method is selected, and the air bubbles inevitably occur when the time is long. Moreover, if there are many irregularities and bends on the concrete wall, bubbles are more serious. The method of freeing bubbles in the adhesive can remove bubbles by the inherent function of the adhesive and can also eliminate bubbles in construction.

1) Bubble removal by the unique function of the adhesive:

The conditions of the adhesive which can adhere the multilayer printed material to the curved concave-convex concrete wall without bubble in construction without bubble are as follows.

1. The adhesive's tacky is strong so that the adhesion is perfect.

2. It should be cured as soon as possible after being adhered to.

3. Must be durable to withstand temperature changes and rain or moisture.

As adhesives that meet the above conditions:

Second Generation Adhesive (SGA), called the second generation of adhesives, separates chlorosulfonated polyethylene (trade name Hyparon) into two themes and meets them instantaneously to prevent the formation of bubbles. It is very suitable as an adhesive.

Both the adherends separated by the main component (A) composed of the hyperparon-30, the acrylic monomer and the peroxide polymerization initiator, and the main component (B) composed of the hyparon-30 and the acrylic monomer and the reducing agent It is a method of bonding together after applying each other. It is an adhesive that reacts and bonds at the moment when both adhesives meet. Here, the polymerization initiator of the subject (A) and the reducing agent of the subject (B) may be replaced with various kinds of compounds. 100 g / m <2>-100 g / m <2> of main body (A) is apply | coated as a spray to a concrete wall surface, and main body (B) adhere | attaches the thing which apply | coated 100 g / m <2> -10 g / m <2> of multilayer printed material to each other.

As a conventional commercial adhesive agent, the method of selecting an adhesive which hardens by reacting with a water-soluble epoxy adhesive and water in a water-soluble adhesive as a counterpart adhesive was chosen. The adhesives used are as follows.

A mixture of 100 parts by weight of EM-101-50 (product of Korea / Kukdo Chemical Co., Ltd.) and 35 parts by weight of brand name H-21 (product of Korea / Kukdo Chemical Co., Ltd.) as a polyamide curing agent as a two-component water-soluble epoxy. 100 g / m 2 to 100 g / m 2 are coated and used.

Since the polyurethane-based adhesive has a property of curing by reacting with water, 50 g / m 2 to 500 g / m 2 was applied to the multilayer printed material, which was used as a counteradhesive adhesive of a water-soluble epoxy adhesive previously applied to concrete walls. Polyurethane was used by mixing 100 parts by weight of the trade name U-500 (product of Korea / Kukdo Chemical Co., Ltd.) and 5 parts by weight of UCX-877 (product of Korea / Kukdo Chemical Co., Ltd.).

As the instant adhesive, 2-cyanoacrylate is cured by a small amount of water as an initiator, and it has a property of instantaneous strong adhesive force due to intermolecular force or hydrogen bonding of the to-be-adhered agent, and thus 50 g / m 2 to 500 g / It can be partially applied to the curved concavo-convex part with a lot of room for foaming. And it was used as a counterpart adhesive of the water-soluble epoxy adhesive applied to the concrete wall surface. The trade name of the instant adhesive was LOCTITE 401 (Korea / Loctite Co., Ltd.).

2) How to remove bubbles in construction:

Since the substrate 10 uses PE, PP, and PVC heat shrinkable films having a thickness of 10 μm to 100 μm, when 120 ° C. hot air is applied to the multilayer substrate based on the substrate, the substrate 10 is contracted by digging into the concave-convex wall. In this shrinkage process, if the multilayered printed material is not sufficiently pressed against the concave-convex wall surface, it is possible to completely fill the concave-convex wall surface by pressing only the part again with the apparatus of FIG. 6. 6, the metal frame 80, the compression handle 81, the plastic bag 82, a paraffin 83 near a softening point of 60 ° C., a heating coil 84, and a tightening screw 85 are included. have.

In this way, when the multi-layered print is adhered on the concrete surface, the entire surface is evenly spread with a hot air fan at 120 ° C, and the heat shrink film penetrates into the uneven part. After 24 hours peel off the substrate (10) construction is finished. Tensile bond strength after full curing after 24 hours is 320 kgf / ㎠.

Reflective multilayer printing has the same apparent results as conventional lane painting, but the most important feature of the lane is the addition of reflection at night, and the construction time is several times faster. Currently, effective reflection paints have not been developed. Therefore, various types of vertical structures are installed as reflective structures, which are very expensive in terms of cost and are not free to install. In addition, it was developed as a multi-layered print that can be applied to the curved bumps and walls of concrete using the same principle as the reflective lane on the pavement. In addition, large-scale concrete structures such as football, baseball, and main stadiums are difficult to finish with expensive interior and exterior materials, so multilayer printing is very effective. It can also be decorated as a stylish print on a rugged concrete retaining wall along the road.
