After the coloring process, the top sheet 7 formed by bonding and integrating the fibrous sheet 6 and the top sheet 4 by peeling off the template, and then adhering the decorative sheet 1 on the surface of the top sheet 4 of the top sheet 7 as described above It is best to make decorative pieces 5. That is, the mold release plate 9 is formed by providing a mold release layer on the surface of a rigid substrate 15 such as a plywood, MDF, or veneer chipboard. The mold release layer is formed by pasting self-polymerized terephthalate on the surface of the substrate 15. It is formed by ethylene glycol ester, polypropylene, polyethylene, poly amide, or a selected resin film 16 in which two or more kinds are mixed. Adhesive film for stripping template 9 and adhesive 6

It can be performed by any method such as spot welding, heating, and pressure welding, but it needs to be firmly adhered so that it cannot be easily peeled off. 'Next' First, a fibrous sheet 6 is adhered to the surface of the film 16 to which the release sheet 9 is attached. It is preferable to use an acrylic adhesive for bonding the fibrous sheet 6 to the adhesive of the release sheet 9. After the adhesive is applied to the surface of the release sheet 9, the fibrous sheet 6 is superposed thereon, and the fibrous sheet 6 can be adhered to the surface of the release sheet 9 by heat pressing. Secondly, the top plate 4 is adhered to the surface of the fibrous sheet δ adhered to the release sheet 9 »The adhesive for adhering the top plate 4 to the fibrous sheet 6 is preferably a modified vinyl adhesive or a latex adhesive. After the adhesive is applied to the surface of the fibrous sheet 6, the top plate 4 'is superposed thereon, and the top plate 4 can be adhered to the surface of the fibrous sheet 6 by heat-pressing it.

As shown in (3) and (b), place the fibrous sheet 6 and the top plate 4 on: After the template 9, grind the surface of the top plate 4 as necessary, and then, Top to top: Choi painting's coloring treatment. The coating is performed on the surface of the top plate 4 by scraping the surface of the top plate 4 and wiping it off as if the liquid paint was applied on the surface of the top plate 4. After the operation of making the coating enter the duct of the top correction,

4 6 6 17s V. Description of the invention (9) Dry and work. The top sheet 4 and the fibrous sheet 6 are adhered to form a top sheet 7 ′. However, since the top sheet 7 is adhered to the surface of the release sheet 9, the top sheet 7 is soft and easy to bend, and because of the rigidity of the release sheet 9, the top sheet 7 Will not bend * When the surface of the top plate 4 is ground or painted, the top plate 7 will not be sufficiently ground due to the bending of the top plate 7 and the coating will not be able to fully enter the top plate due to insufficient scraping during coating. The duct of 4 can be painted on the surface of the top plate 4 with beautiful finishing.

Here, when the fibrous sheet 6 of the top sheet 7 is subjected to painting or the like treatment on the surface of the top sheet 4, it must be peeled off from the surface of the release sheet 9 after the painting or other treatment is completed. Therefore, as shown above, the film 16 forming the release layer of the release sheet 9 is a selected one made of polyethylene terephthalate, polypropylene, polyethylene, nylon, or a mixture of two or more thereof. The adhesive made of resin and used to adhere the fibrous sheet 6 to the release sheet 9 is an acrylic adhesive.

For example, 'if the film 16 forming the release layer 9 of the release sheet 9 is made of polytetrachloroethylene (Teflon), the release property of the release sheet 9 is too high, and the adhesive force of the fibrous sheet 6 to the release sheet 9 is changed. Weak 'When the surface of the top plate 4 is subjected to grinding or painting, the top plate 7 is peeled from the release plate 9 and cannot be sufficiently ground, and it is not enough to brush, and the coating cannot enter the duct of the top plate 4 sufficiently. Give specific examples of this situation. A film 16 'made of Teflon was adhered to the surface of the substrate 15 formed of the plywood to prepare a release sheet 9. After applying acrylic adhesive on the surface of the release sheet 9 at an application amount of 3 g / sq. Ft. (3 3.3 g / m2), a fibrous sheet 6 made of polyester nonwoven fabric is superimposed thereon. By thermally pressing the fiber at a temperature of 00, a time of 20 seconds, and a pressure of 7 kg / cm2 (0. 69 MPa), the fiber is compacted.

Page 12 V. Description of the invention α〇) The platen 6 is adhered to the surface of the release plate 9. Next, the surface of the fibrous sheet 6 is coated with a urethane-deteriorated vinyl adhesive at an application amount of 7 g / feet (77.8 g / m2), and then the top plate 4 of the auxiliary member is superimposed thereon. The top plate 4 was adhered to the surface of the fibrous sheet β under the conditions of 〇 ° C, time 60 seconds, and pressure 7 kg / cm2 (0.69 MPa). Here, the fibrous sheet 6 has no adhesiveness to the release sheet 9. When the surface of the top plate 4 is subjected to a process such as grinding or painting, the top sheet 7 is peeled from the release sheet 9. For example, if the film for the release layer 9 of the release sheet 9 is made of polyvinyl chloride, the mold release property of the die sheet 9 becomes too low, and the adhesion of the fibrous sheet 6 to the release sheet 9 becomes too strong. The top sheet 7 cannot be peeled off from the template 9, and the top sheet 7 cannot be produced. List specific examples of this situation. A film 16 made of polygasified ethylene was adhered to the surface of the substrate 15 as described above, and a release sheet 9 was produced. A fibrous sheet 6 was adhered to the surface of the release sheet 9 with an acrylic adhesive as described above. »Secondly, the top plate 4 is adhered to the surface of the fibrous sheet 6 with a urethane-modified vinyl adhesive as described above. Here, the fiber 6 has good adhesion to the release sheet 9 but cannot remove the top sheet 7 from the release sheet 9. For example, if it is used to adhere the fibrous sheet 6 to the adhesive of the release sheet 9 S: I is an ethylene-based adhesive. The fibrous sheet 6 has weak adhesion to the release sheet 9. When the surface of the top plate 4 is ground or painted, the top plate sheet 7 will be peeled off. It is fully ground, and the scraping brush is not enough, so that the material can not be filled into the pipe of the top plate 4. List specific examples of this situation. ° The surface of the substrate 15 described above was pasted with a resin film 16 made of acrylic and polyethylene mixed at a weight ratio of 8: 2 to produce a release sheet 9. At this removal_ P.13 ** 7 466 1 V. Description of the invention (11) The surface of template 9 is coated with vinyl acetate adhesive at an application amount of 3g <feet 2 (33. 3g / m2). The same fibrous sheet 6 is bonded as described above. Next, the top sheet 4 is adhered to the surface of the fibrous sheet 6 with a urethane-modified vinyl adhesive as described above. Here, the fibrous sheet 6 has no adhesiveness to the release sheet 9, and when the surface of the top plate 4 is subjected to a process such as grinding or painting, the top sheet 7 is peeled from the release sheet 9.

After the top sheet 7 is temporarily adhered to the release sheet 9 as described above, after the surface of the top sheet 4 is painted and colored, as shown in FIG. 3 (c), the top sheet 4 and the fibrous material can be peeled off as shown in FIG. 3 (c). The sheet 6 is pasted into an integrated top plate sheet 7. Then 'the decorative plate 1 made by adhering the decorative plate 1 to the top plate 7 is affixed to the surface of the core material such as building materials for surface decoration. In order to bend along the table of the core material such as building materials, the top plate 7 is required. Department is soft. Therefore, as described above, the adhesive for bonding the top plate 4 to the fibrous sheet 6 uses a modified vinyl-based adhesive or a latex-based adhesive such as urethane modification to form the top sheet with flexibility. 7 is the best.

For example, 'If an ethyl acetate adhesive is used on the adhesive for bonding the top plate 4 to the fibrous sheet 6, the softness of the top plate 7 where the top plate 4 and the fibrous sheet 6 are bonded together is insufficient. When the surface of a core material such as a building material is bent, a crack or the like may occur in the top sheet 7. List specific examples of this situation. A film made of a resin mixed with polypropylene and polyethylene at a weight ratio of 8: 2 was adhered to the surface of the substrate 15 as described above to prepare a release sheet 9. The fibrous sheet 6 is adhered to the surface of the release sheet 9 with an acrylic adhesive as described above. Next, ‘apply 7 g / sq. 2 (77. 8 g / m2) on the surface of the fibrous sheet 6 and apply the vinyl acetate adhesive’ on the same surface as above.

4 6 6 17 6 V. Description of the invention (12) '-4. Here, the fibrous sheet 6 has good adhesion to the release sheet 9, and the top sheet 7 has good peelability from the release sheet 9. However, the load value of the top sheet 7 obtained by peeling from the release sheet 9 in the ring rigidity test described later is 450 g, and the softness of the sheet 7 is low. The decorative pieces 5 obtained as described above are stacked on the surface of the core material 17 of the building material for the decoration of the surface of the building material. The core material 7 can be formed with a human board, MDF, veneer chipboard, or the like. Then, by applying an adhesive on the side of the 6th side of the fibrous sheet of the decorative part &quot; 5, the willow part 5 is superimposed on the surface of the core material 17 &apos; using a Gukong forming machine, a profile laminator, and a flat press. For a bed or the like, a decorative member 5 is stacked on the surface of the core material 17 with the backing plate 1 as the outer side, and a building material A that decorates the surface of the material 17 shown in FIG. 4 with a skirt 5 is obtained. Here, the contour laminator 18 includes a plurality of compacting rollers 19 arranged along the periphery of the core material 17 as shown in FIG. 5 (a). The side is rolled on the side along the curved surface of the core material 17 so that the decorative member 5 can be stacked on the surface of the core material 17 ^ Then, a two-liquid solvent is used on the adhesive for adhering the decorative member 5 to the core material 17 Type urethane-based = iso-solvent type adhesive 'as shown in Figure 5 (b), pumped from the roller 20 = long decorative parts 5 feed while using an adhesive application device such as a knife applicator 2 丨 The adhesive is applied to the decorative part 5 so that it passes through the drying area 22 to volatilize the adhesive and the container, and then feed the core material 17 in the direction of the arrow while profiling with _ pressing the roller 19 to decorate The pieces 5 are stacked on the surface of the core material π. In addition, in the case of using the solvent-free adhesive such as reactive urethane = refining adhesive when the piece 5 is adhered to the adhesive of the core material 17, it is necessary to dry the refrigerant, as shown in Figure ⑷ As shown, the long decorative glaze is drawn out from the roller 2G
