The above-mentioned foaming sheet 9 is a technique for transferring the layer 9 on the textured surface, and has the following problems: % The production cost of the transfer film 91 is high, and the reason is that in addition to the use of the film, the transfer is made. In the film process, since the film of the money has a telescopic property, it is necessary to pass through several times of coloring to achieve the desired pattern color, thus wasting a considerable amount of the transfer film 9 丨, on the other hand, the transfer film / transfer The film recycling remaining after printing is also not in compliance with environmental requirements. 2, 2, due to the foaming process of the foaming board 9, usually in the foaming of the mold spray release agent, so that the finished product after foaming can be smooth * first, but also caused the surface of the foam board Attached with release agent', release mold

The practical remedy is to improve the adhesion of the surface of the foamed board to the surface of the foamed board, but its function is + lip, limited, still β is easy The disadvantage of stripping. & 201018562 3. The layer 9 3 transferred on the foamed board 9 has only a slight micro-ink thickness. After being frequently stepped on or hit by a rough object, it is easily worn and destroys the original appearance of the layer. Therefore, how to solve the problem that the above-mentioned textured surface of the foamed sheet 9 is on the process is the focus of the present invention. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above problems and provide a method for producing a layer on a surface layer of a foamed sheet. The dye of the dyed paper is heated and vaporized to be adhered to the surface layer of the foamed sheet. The bubble board process is environmentally friendly, process simplification and cost reduction. For the purpose of the foregoing, the foamed sheet of the present invention is formed by foaming a mold, which forms a textured road surface on the surface of the foaming process which is pressed by the mold, and the foamed sheet is cut and cut relative to the textured surface. The other side forms a cutting surface having a foaming hole, and the foaming board is coated on the cutting surface with a dyed paper having a decorative pattern formed by dye, and the dyed paper is heated by hot pressing on the dyed paper. And transferring to the cutting surface, and the dye penetrates into the foaming hole of the foaming plate to form a layer with a decorative pattern on the surface of the foaming plate. The above and other objects and advantages of the present invention will be readily understood from Of course, the invention may be varied on some of the components, or the arrangement of the components, but the embodiments selected are described in detail in the present specification, and the construction thereof is shown in the drawings. [Embodiment] 201018562 Please refer to Fig. 1 to Fig. 3, which shows the structure of the embodiment selected for the present invention, which is for illustrative purposes only and is not limited by such structure in the patent application. The present embodiment provides a method for producing a layer on the surface layer of a foamed sheet, and the foamed sheet 1 described herein is formed by foaming a mold (not shown). In the present embodiment, the foamed sheet 1 is made of ETHYLENE VINYL ACETATE (EVA). In the foaming process, since the upper surface and the lower surface of the mold have a grain in the foaming process, the foamed sheet 1 which is formed is formed into the same texture as the mold on the upper and lower surfaces by being pressed by the mold. The textured road surface 11 has a density which is generally higher than the inside of the foamed sheet 1. After the foamed sheet 1 is foamed, it is divided into several pieces by cutting (may be divided into two or divided into many), so the cut surface (ie, relative to the textured surface 1 1) The other side) forms a cut surface 1 2 . The cut surface 12 is formed by cutting the foamed sheet 1 between the upper and lower surfaces. Since the density of the inside of the foaming sheet 1 is low, there is a foaming hole 13 on the surface of the cut surface 12. Next, the foamed sheet 1 is laid with a dyed paper 2 on its cut surface 1 2, and the dyed paper 2 described above has a dye to form a decorative pattern. The dye of the dyed paper 2 is heated and vaporized on the foamed sheet 1 by a hot pressing procedure to be transferred onto the cut surface 1 2 'dye and penetrated into the foamed hole 13 of the cut surface 1 2 to be attached to form a hair The surface of the bubble board 1 has a layer 3 of a decorative pattern on the surface. In the present embodiment, the hot pressing process forms the layer 3 by rolling the dyed paper 2 on the foamed sheet 1 by the preheated roller 4 (of course, as shown in the figure of 201018562 4, the use of the pre- After the hot stamper 5, the dyed paper 2 is pressed against the foamed sheet 1 on the foamed sheet 1, and the layer 3) is formed on the foamed sheet 1. Referring to FIG. 3, in which the layer 3 is formed on the cutting surface 1 of the foamed sheet 1 by the above-described manufacturing method, the dye is infiltrated into the cut surface except that the surface of the cut surface 2 is dyed with a dye. And adhering to the foamed structure of the foaming hole 13, the dye of the dyed paper 2 can be surely adhered to the cut surface 12, so that it adheres to the layer 3 of the cut surface 12 and is not easily worn or scraped, and can be long-lasting. The beauty of the pattern. Therefore, the layer 3 made of the foamed sheet 1 by the above-described production method has the following advantages over the conventional transfer technique: 1. Since the dyed paper 2 is used to print the dye on the paper film, the advantage is The paper film has a very small amount of expansion and contraction, is easy to print, and the paper film is low in cost, and the manufacturing cost can be relatively reduced. What remains after dyeing is a paper film, which can be reused through recycling, without the problem of polluting the environment. 2. The cut surface of the foamed sheet 1 is completely free of release agent, and is cut by The cut surface 1 2 has the characteristics of the dense foaming hole 13 , so that the dyed material can easily penetrate into the cut surface 12 and adhere to the foamed structure of the foamed hole 13 to make the dye adhere more reliably to the cut surface. 12 on. 3. Appearing 'Because the dye adheres to the cutting surface 12, it is stepped on the cutting surface 12 of the adhesion layer 3, and the layer 3 is not damaged, which affects the overall appearance. Through the development process in practice, it has been found that the layer 3 of the foamed sheet 1 is formed by the method of the present invention, because the pavement 1 1 remains a release agent, and the foam is formed when the foam is formed. The surface layer density of the pavement 1 1 201018562 is higher than that of the non-foaming hole 13 3, and the dye is not easy to adhere. When the dyeing is applied, the grain of the grain surface 11 protrudes and the two portions of the concave portion have obvious chromatic aberration, and the concave portion is injured. The degree of dyeing is also not ideal, and the overall visual appearance is less beautiful. Through repeated research and development, the above-mentioned layer 3 manufacturing technology can be invented, and thus the technical difficulty of the present invention can be seen. Of course, there are still many examples of the present invention' in which only the details change. Please refer to FIG. 5, which is a second embodiment of the present invention, in which the layer 3 is formed on the cutting surface χ 2 of the foamed sheet 1, and then heat-treated on the cutting surface 1 2 The pro-wheel 6 having a wide grain is rolled on the cutting surface 1 2 after the hot flooding, and the cutting surface 12 having the layer 3 and the anti-slip texture is formed on the foam board. Therefore, the foamed sheet i of the present embodiment has the layer 3 in addition to the first embodiment, and is made of a slip-proof and mosquito road on the cutting layer 1 2 to achieve the dual effects of aesthetics and slip resistance. The above description of the embodiments is intended to be illustrative of the invention, and is not intended to limit the scope of the invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can indeed achieve the stated purpose, and is in accordance with the provisions of the Patent Law.
