  In 1st invention, it is the surface decoration material comprised by a decorative sheet being affixed on the surface of a planar member, and the said planar member is arrange | positioned so that it may mutually have a predetermined width | interval, Provided is a surface decorative material characterized in that a bending groove is provided on the back side of the decorative sheet.

  The surface decorative material having the above-described structure is used by flexibly folding the decorative sheet because the adhesive groove and the planar member layer are not present on the back side of the decorative sheet in the folding groove portion. The white sheet base material is not cracked and the white sheet base material is not exposed, and the decorative sheet itself is not cracked and broken.

  Various materials can be used as the planar member, and a wood molded board such as MDF (medium density fiber board) is preferably used. As the decorative sheet, various resin sheets such as an olefin sheet having a decorative layer printed on the surface and decorative paper are used.

  In the second invention, a groove is formed in the planar member base plate, a decorative sheet is attached to the entire one side surface of the planar member base plate so as to cover the groove, and the bottom portion of the groove is cut off. Provided is a method of manufacturing a surface decorative material, which is performed by separating a planar member base plate and forming a bending groove.

  According to the above manufacturing method, the folding groove is formed by cutting the bottom of the groove formed on the planar member base plate in which the decorative sheet is integrated on the surface side. Thus, the surface decorative material provided with high accuracy can be easily manufactured, whereby the surface decorative material of the first invention can be easily manufactured.

  According to the first aspect of the present invention, there can be obtained a surface decorative material that is used with good appearance without being damaged even when it is bent. According to the second aspect of the present invention, it is possible to easily produce a surface decorative material that is used with good appearance without being damaged even when it is bent.

  FIG. 1 shows a side configuration of a first embodiment of the surface decorative material of the present invention. The surface decorative material 1 has a decorative layer printed on the surface so as to cover the surfaces of two MDFs (planar members) 3. An olefin sheet (decorative sheet) 4 is pasted. The MDF 3 having a thickness of about 7 mm is used. One MDF 3 has R portions 5 at both ends thereof, and the other MDF 3 has R portions 5 at outer ends thereof. The surface decorative material 1 is configured to have a bending groove 7 on the back side of the olefin sheet 4 by arranging the inner end edges thereof with an interval of about 5 mm.

  FIG. 2 shows a state where the surface decorative material 1 is bent in the artificial material 100. The surface decorative material 1 is affixed so that the folding groove 7 portion is bent so that the back surface of the olefin sheet 4 is along the R portion 5 of the inner end edge of one MDF 3 to cover the construction material base material 20. At that time, the olefin sheet 4 is flexibly folded because the adhesive layer and the MDF layer are not present on the back surface. In particular, in this embodiment, the olefin sheet 4 is folded along the R portion 5 of the MDF 3, so that the folds more flexibly. Thus, damage such as cracks in the olefin sheet 4 is reliably avoided.

  Next, a method for manufacturing the surface decorative material 1 will be described. First, as shown in FIG. 3, an MDF material (planar member base plate) 10 having R portions 5 at both end edges and having a groove portion 9 having one wall at the center as the R portion 5 is obtained by molding. Next, as shown in FIG. 4, the olefin sheet 4 is pasted so as to cover the entire surface of the MDF material 10. Next, the surface decorative material 1 having the bending groove 7 shown in FIG. 1 is obtained by cutting off the bottom 11 of the groove 9 at the dotted line position. The excision of the bottom 11 of the groove 9 may be performed by shaving the entire surface of the MDF material 10.

  As described above, the surface decorative material 1 in which the bent portion is formed only of the olefin sheet 4 and the bending is performed flexibly is obtained. A similar surface decorative material can be obtained by placing two MDFs at predetermined intervals so that a bending groove is formed, and attaching an olefin sheet so as to cover them, but different. It is necessary to obtain the shape MDF by molding, and it takes much labor to align the olefin sheets with accuracy and to attach the olefin sheet. According to the manufacturing method, the surface decorative material 1 in which the bending groove 7 is accurately provided at a predetermined position can be easily obtained.

  Furthermore, according to the above manufacturing method, it is possible to easily provide the R portion 5 at the bottom of the bending groove 7, and as a result, as shown in FIG. Is obtained. Conventionally, when such an R surface is formed in the bent portion, it takes a lot of trouble by separately filling a resin inside the decorative sheet.

  The surface decorative material 1 of the second embodiment shown in FIG. 5 uses a MDF 3 in which the R portion 5 becomes a chamfered portion 13, and as shown in FIG. A bent form with can be obtained. When the surface decorative material 1 of this embodiment is used, the olefin sheet 4 is bent at two places, but both are flexibly bent and no damage occurs. In addition, the surface decorative material 1 can be easily obtained in the same manner with the dimensional accuracy by the manufacturing method of the above embodiment.

  The surface decorative material 1 of the third embodiment shown in FIG. 7 includes two folding grooves 7 with a predetermined width interval, and is used in a form that bends at two locations as shown in FIG. . When the surface decorative material 1 of this embodiment is used, the olefin sheet 4 is bent at two places, but both are flexibly bent and no damage occurs. As shown in FIGS. 9 and 10, the surface decorative material 1 can be easily obtained in the same manner by the manufacturing method according to the above-described embodiment with excellent dimensional accuracy.

  The surface decorative material 1 of the fourth embodiment shown in FIG. 11 has a thin shape using a MDF 3 having a thickness of 1 mm. This is also manufactured in the same manner as in the above embodiment, and the bending is performed flexibly in the same manner. The surface decorative material 1 is used for production of a construction material in the same manner as the surface cosmetic materials 1 of the above-described embodiment, and a large size is cut and used so as to be directly attached to the construction material of a house at a renovation site. Can be used. Resin decorative sheets that do not integrate MDF, etc., have excellent flexibility and can be easily used for bending. However, since the entire structure is flexible, there is a problem that it is difficult to paste and difficult to apply. The surface decorative material 1 is easily pasted and used without these problems.
