(Industrial Application Field) The present invention relates to a flexible bead-coated sheet. (Prior art) The durability of the surface can be improved by making it weatherproof, water resistant, and abrasion resistant, the surface can be made aesthetic to improve its decorative properties, and the surface can be made to prevent glare from reflected light. It is known that glass bead coating is applied directly to panels of a certain size for this purpose. It is also known that extremely fine highly reflective glass beads are kneaded with a synthetic resin material and made into a film or sheet by extrusion or other means and used for traffic signs. (Problems to be solved by the invention) Among the above conventional methods, the former method is applied directly on-site or by bead-coating the surface to which it is applied, so equipment for that purpose is also required, and its use is extremely limited. . Moreover, in the latter case, glass beads are embedded in a synthetic resin material, and since a non-transparent material is used, no decorative effect can be expected. (Means for Solving the Problems) In view of the above problems, the present invention separately prepares a flexible bead-coated sheet in advance, so that it can be used immediately for decorative or functional purposes. The purpose of this invention is to improve the performance and facilitate on-site construction, and furthermore, by demonstrating the various practical performances of this invention, it is possible to use it for a wide range of purposes. To achieve this, a transparent bead layer consisting of countless transparent beads made of glass or plastic with a particle size of 300 μm or more and treated with a silane coupling agent is integrated on the surface of the flexible sheet via an adhesive layer. We adopted a structure in which layers are formed. (Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. In FIG. 1, 1 is a flexible sheet;
A transparent bead layer 3 is placed on its surface via an adhesive layer 2.
are integrally laminated and fixed, and on the other hand, an adhesive layer 4 is formed on the back surface of the sheet 1, and a release paper 5 is further stuck on the back surface of the layer 4. What is shown in Fig. 2 is a transparent cover coat layer 6 with a thickness of 500 mμ or less on the surface of the transparent bead layer shown in Fig. 1.
was applied. The flexible sheet 1 used in this invention is 20~
3000 mμ, preferably 100 to 2000 mμ,
It has properties such as water resistance, weather resistance, and corrosion resistance, and is preferably printed with a pattern or colored depending on the purpose, and in some cases is adhesive-treated. Plastic films such as polyvinyl chloride, polyethylene, polypropylene, polyester, acrylic, and polycarbonate are usually used, but they can also be woven from natural fibers, chemical fibers, or synthetic fibers such as cotton, linen, rayon, nylon, polyester, and acrylic. Cloth or nonwoven fabric, paper such as synthetic or natural paper, metal foil, etc. are selected and used depending on the purpose. The adhesive of the adhesive layer 2 is flexible, such as urethane-based, acrylic-based, epoxy-based, soft-based, silicone-based, etc., and has properties such as transparency, water resistance, weather resistance, and corrosion resistance. This is uniformly applied to the surface of a flexible sheet 1 such as a plastic film using an appropriate means, such as a roll coater or spray, depending on the bead size, to an optimal thickness so that the beads are not buried in the adhesive layer. At this time adhesive layer 2
If the beads are buried in the beads, the decorative and functional effects due to the size and transparency of the beads cannot be expected. The cover coat agent for the cover coat layer 6 that covers the surface of the three layers of transparent beads is made of the same material as the adhesive for the adhesive 2 described above. Note that the thickness of the adhesive layer 2 and the cover coat agent layer 6 is preferably 1/2 or less of the bead particle diameter. Note that the adhesive and cover coat agent forming the adhesive layer 2 and the cover coat layer 6 may be based on ultraviolet curing reactive synthetic resin depending on the type of flexible sheet. The transparent bead layer 3 is sprinkled on the surface of the uncured adhesive layer 2 and is bonded to the surface.The beads 3 have transparency, weather resistance, and water resistance, and are coated with a silane coupling agent as an adhesive treatment. Use the processed one. This is because, in the present invention, since beads with a relatively large particle size are used as described later, it is necessary to improve the adhesive strength to prevent them from falling off. The beads may be made of glass, hard plastic, soft plastic, or the like. Examples of the coupling agent used in the silane coupling agent treatment include aminosilane, glyoxide silane, and acrylic silane, among which acrylic silane treatment is preferred. In the present invention, beads with a particle size of 300 μm or more are used. If the diameter is less than 300 μm, the transparent bead layer will have significant diffused reflection, and the surface will become whitish.
Since the lens effect of the beads is reduced, it becomes difficult to obtain the decorative effect of making the pattern drawn on the adhesive surface of the sheet or the surface of the flexible sheet three-dimensionally stand out according to the present invention. The curing and drying conditions include heating the sheet 1 on which the beads 3 are evenly adhered at a low temperature or as necessary;
Alternatively, it is cured by projecting ultraviolet rays (including electron beams) to form the desired flexible sheet. The heating method uses an infrared heater, an electric oven, or the like. For example, in the case of a soft PVC sheet with high heat shrinkability, the temperature may be adjusted as necessary by water cooling or air cooling, or the sheet may be dried at room temperature or cured at 80° C. or lower using a low temperature curing resin. The bead-coated sheet according to the present invention can be applied to a plastic plate, a metal plate, a glass plate, a concrete plate, or any other intended use as exemplified below by peeling off the release paper 5 and applying an adhesive (rubber-based, ester-based, etc.) layer. 4, but the adhesive layer 4 and release paper 5 are not necessarily required. The embodiments of the present invention are as described above, and by suitably applying its practical performance and performance, a wide range of applications can be expected. An example of this is shown in the table below.

When used in panels, it can respond to diversifying needs, and also facilitates mass production, easy removal, and stable quality. Furthermore, the surface of the target board to which the sheet of the present invention is attached has improved durability such as weather resistance, water resistance, abrasion resistance, and corrosion resistance. In addition, in the present invention, since the transparent bead layer uses large beads with a particle size of 300 μm or more, the lens effect of the beads can be effectively exhibited, and the sheet according to the present invention can be attached. The pattern drawn on the surface or the surface of the flexible sheet can be made to stand out three-dimensionally, and an excellent decorative effect can be achieved. Furthermore, although the beads have a large diameter, they are treated with a silane coupling agent, so that they firmly adhere to the adhesive layer and are difficult to fall off and have excellent durability.
