The following (1) to (1)
There was the problem (5). (1) In order to obtain a decorative plate, one side of a thin flat plate is coated, so that when the paint is dried, warpage is likely to occur. For this reason, it was difficult to cut the decorative plate and adhere to the flat plate. (2) Since the technique applies only to a pair of facing wooden mouths, the other wooden mouths cannot be directly applied to members constituting the appearance. (3) As a method of treating the remaining tip, for example, a method of painting the remaining tip at the same time as painting the flat part with a flow coater has been considered. However, with this method,
Kiguchi has an elevated surface during painting, and the coating thickness is thin, so during grinding, the wood base of the decorative board comes through at the corner where the kiguchi to be painted and the kiguchi to attach the painted decorative board are joined. It was easy. (4) A method was also considered in which a painted veneer was attached to the remaining wood edge. In this case, as shown in FIG. 6, when the painted decorative boards 30 and 31 are attached to the opening of the board 1, the opening 32 of the painted decorative board 30 is exposed, and the wood base and the adhesive layer 15 impair the appearance quality. I will. That is, there is a problem that the side surface of the corner portion viewed from the direction E is inferior in aesthetic appearance. (5) As a method to prevent this, it is conceivable to glue the painted veneer, but if the adhesive layer comes out at the corners or the width of the kiguchi does not exactly match the length of the veneer, it will be bonded. Inviting defects, and because the decorative panel is thin, the adhesive area of the fastening surface is small, so the adhesive strength is weak,
If the decorative board changed its dimensions due to changes in temperature and humidity, it was easy to peel off the adhesive and create a gap.

FIGS. 2 to 4 are perspective views showing a step of attaching a coating film sheet to a plate material, and FIGS. As shown in FIG.
a, the groove 2a is bent at opposing corners 1c, 1c of the lip, and attached to the lip 1a, 1b, and the lip 1a,
1b. Coating sheet 2 is groove 2
Since it has a, the coating film sheet 2 is hardly broken at the time of bending, and since it does not form a bend R inside after bending, it is easy to conform to the corner 1c of the opening. In addition, there is an advantage that the periphery of the corner of the finished plate material does not swell and the smoothness is good. If one or more grooves 2a are formed in the coating film sheet 2,
The coating film sheet 2 can be stuck on at least the entire two surfaces of the wood ends 1a and 1b.

耐候性が低下するという問題がある。[0008] The coating sheet 2 must have a groove 2a so as to be able to match the corner of the opening of the board, and have a shape that can match the dimensions of the openings 1a and 1b. When the coating sheet 2 is adhered to the cut ends 1a, 1b, 1a, the width w of the coated sheet 2 is preferably equal to or slightly larger than the thickness of the cut ends 1a, 1b of the plate material. it is preferred spacing l 2 of smaller or slightly equal to the width of the cut end 1a or 1b. If the distances l 1 and l 3 between the ends of the paint film sheet 2 and the grooves 2a are equal to or slightly larger than the width of the wooden edge 1a of the plate material, one paint film sheet 2 is used to make the plate material. A plurality of wood openings 1a, 1b, 1a can be simultaneously dressed. The thickness t 1 of the coating sheet 2 is preferably about 1 to 5 mm.
If it is less than 1 mm, it is difficult to form the groove 2a, and there is a problem that the portion of the groove 2a is easily broken.
There is a problem that the weather resistance is reduced.

粧済み板材の角部が膨らまないという利点がある。The shape of the groove 2a is determined so as to conform to the shape of the corner of the opening. If the cross-sectional shape of the groove 2a is V-shaped, the groove 2a can be easily covered on the corner of the opening, the corner of the finished plate does not bulge, and the periphery of the corner has a smooth surface. When the cross-sectional shape of the groove 2a is V-shaped, the opening angle α (when the coating film sheet 2 is placed on a horizontal table) is about 90 to 120 degrees, The corners have a smooth surface. The thickness t 2 of the groove 2a is, if 0.2 to 0.8 mm, a coated film sheet 2 can be prevented easily broken by bending at the portion of the groove 2a, the corner portion of the decorative pre plate material is not inflated There is an advantage.

ートの形状によって決められる。Next, a method of manufacturing the coating sheet 2 will be described. FIG. 1 is a perspective view of an example of a molding die for producing a coating sheet. The mold has a cavity 12 for obtaining the coating film sheet 2 by resin casting, and the cavity 12 is provided with a groove forming mold portion 11 for forming the groove 2a. The molding die can be produced using a material that is releasable from the resin used to produce the coating sheet, for example, an olefin resin such as a polyethylene resin. If a mold having a plurality of (three in FIG. 1) cavities 12 is used as a molding die, a coating film sheet can be efficiently molded. The shape of the cavity 12 is determined by the shape of the coating film sheet to be formed.

連結された塗膜シート２が得られるようにする。The groove forming die 11 for forming the groove 2a of the coating film sheet is formed by, for example, processing a rod made of an olefin resin into a desired shape, and bonding the rod to the inner bottom surface of the forming die with a double-sided tape or the like. Can be made. The distance between the groove forming mold parts 11 and 11 is determined so that the inner dimension when the coating film sheet is bent at the grooves 2a, 2a substantially coincides with the width of the opening. Further, it is preferable that the cross-sectional shape of the groove forming mold portion 11 is triangular so that the cross-sectional shape of the groove 2a is V-shaped. As shown in FIG. 1, the height of the groove forming die portion 11 is smaller than the height of the frame of the forming die so that the coating film sheets 2 connected at the groove 2a can be obtained.

シートの硬度を高めてもよい。The coating sheet 2 is formed by injecting a resin liquid for forming a coating sheet into the cavity 12 and curing and solidifying the resin liquid.
It can be easily obtained by cast molding in which the solidified resin sheet is removed from the cavity 12. If the coating film sheet 2 is formed by casting, the groove 2a can be easily formed. The coating film sheet 2 may be transparent or colored with a dye or pigment. In order to obtain a coating film sheet connected at the groove 2a,
The injection depth of the resin liquid is made smaller than the height of the frame and larger than the height of the groove forming mold portion 11. The release coated film sheet may be heated, for example, at about 50 to 90 ° C. to increase the hardness of the coated sheet.

挙げられる。As the resin for forming the coating film sheet, a highly polar crosslinkable (thermosetting) resin can be used. Examples of the polar group include an ester bond, an ether bond, a urethane bond,
And a hydroxyl group. As the resin, a normal unsaturated polyester resin can be used, but a soft unsaturated polyester resin is preferable, and the breaking energy is 40 kg% / mm.
Those having large elongation of 2 or more and relatively high tensile strength are particularly preferable. Such a soft unsaturated polyester resin uses a long chain having a large number of carbon atoms as the hydrocarbon group of the dihydric alcohol component. If such a soft unsaturated polyester resin is used, the groove 2a is hardly broken. Examples of the resin include an acrylate resin such as a polyurethane resin, a diallyl phthalate resin, and a urethane acrylate, in addition to the unsaturated polyester resin.

Before the coating sheet 2 is attached to the wood openings 1a and 1b, the coating sheet 2 is disposed on the other side of the plate 1 as shown in FIG. A pressing sheet 4 for pressing the sheet 2 is arranged, and a pusher 5 for pressing the coating film sheet 2 at the wood ends 1a and 1b of the plate material is arranged on the other side of the pressing sheet 4. On this occasion,
When the sheet 2 is bent at the grooves 2a and 2a, the coating sheet 2 is formed so that the grooves 2a and 2a can match the corners 1c and 1c of the opening.
Is arranged. The glue 1a, 1b is coated in advance with an adhesive for bonding the paint film sheet 2 and the glue 1a, 1b, for example, a urethane resin-based or epoxy resin-based adhesive.

Breakage at the groove 2a can be prevented. In order to perform this local heating, it is desirable to arrange the sheet heater 3 between the coating sheet 2 and the pressing sheet 4. The local heating temperature is preferably 50 to 80 ° C., and the time is preferably 2 to 5 minutes. Further, when an elastic sheet such as a rubber sheet is used as the pressing sheet 4, the surface of the coating sheet 2 is not easily damaged when pressed, and the pressing force becomes uniform.
