Abstract

PURPOSE:To simply manufacture a decorative board formed by sticking decorative sheets of different patterns on their surfaces. CONSTITUTION:When an unbreathing decorative sheet 5 is vacuum pressure fixed on the surface of a breathing base 4 by using a bonding agent 7, a masking sheet 6 is interposed on the surface of the base 4 at a given site 4A so that the base 4 is not bonded with the decorative sheet 5, and the decorative sheet 5 is cut off at the site, and another decorative sheet of different pattern is stuck on the given site 4A.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a decorative sheet material used for door surface materials, inner wall materials and the like.

[0002]

2. Description of the Related Art As shown in FIG. 7, for example, in a flush door (1), face materials (3) are stretched on both sides of a frame (2). The face material (3) is attached to the surface of the base material (4) with an adhesive, and the base material (4) is made of wood board such as plywood or thin wood which is press-formed into a predetermined uneven shape. Makeup sheet
(5) consists of and. The decorative sheet (5) is a plastic sheet such as a polyvinyl chloride sheet with wood grain printed on its surface. In order to adhere the decorative sheet (5) to the base material (4) in the face material (3), it is necessary to adhere the decorative sheet (5) to the uneven shape of the base material (4) by a conventional method. The vacuum crimping method has been applied.

[0003]

However, in the above conventional vacuum pressure bonding method, the base material (4) has one decorative sheet on the entire surface.
Since (5) must be attached, for example, the wood grain pattern is unidirectional as shown in FIG. 7, and it is not preferable for design because it has no accent. It is impossible to place a horizontal grain pattern in the vertical direction and a vertical grain pattern in the vertical cross section.

[0004]

Means for Solving the Problems As a means for solving the above conventional problems, the present invention attaches a masking sheet (6) to a predetermined location (4A) on the surface of a breathable substrate (4), A non-breathable decorative sheet (5) is vacuum-pressed onto the surface using an adhesive (7) from above, and a masking sheet (6) of the decorative sheet (5) is a decorative plate material for cutting off the sticking point. It provides the manufacturing method of (3). A decorative sheet (5A) having a different pattern is attached to the cut-out portion of the decorative sheet (5), or a decorative sheet (5A) having a different pattern is formed on the base material (4) below the masking sheet (6). Adhere 5A).

[0005]

[Function] Non-breathable decorative sheet on breathable substrate (4)
The (5) is vacuum-pressed using the adhesive (7), but since the masking sheet (6) is attached to a predetermined part of the breathable substrate (4), the decorative sheet ( 5) is the base material
Do not adhere to (4). Therefore, the makeup sheet at that point
(5) can be excised, and after excision, a decorative sheet (5A) with another pattern is attached to the location. In this case, the masking sheet (6) may or may not be peeled off.

[0006]

EXAMPLE The present invention will be described with reference to an example shown in FIGS. 1 to 4. (4) is a base material of a face material (3) which is a decorative board material of a flush door, and is a plywood, a thin wooden board, a pulp. It is made of a breathable material such as a board and is formed into a predetermined uneven shape by press molding or the like. As shown in FIG. 1, an adhesive (7) is applied to the surface of the base material (4) by spraying, flow coating, etc., and a masking sheet is provided at a predetermined portion (4A).
(6) is affixed, and the base material (4) has a lower jig (8) having a large number of vacuum holes (9) on the upper surface and an upper jig having a silicone rubber sheet (10) stretched on the lower surface. Vacuum crimping device consisting of tool (11)
Installed on the lower jig (8) of (12), covering the decorative sheet (5) from above, vacuuming through the vacuum path (13) of the lower jig (8), Pressurized air is sent into the jig (11) from the pressure air path (14) to expand the silicone rubber sheet (10) and press the decorative sheet (5), as shown in FIG. 5) is pressure bonded to the surface of the base material (4).

The decorative sheet (5) is made of a non-breathable plastic sheet such as a polyvinyl chloride sheet, a polyester sheet, a polyamide sheet, etc., and if necessary, it is heat-softened and vacuum-pressed onto the surface of the substrate (4). As the masking sheet (6), a releasable plastic sheet such as polyethylene sheet, polypropylene sheet, polyester sheet, release paper, adhesive sheet or the like is used. The surface of the decorative sheet (5) is provided with a wood grain pattern, and the decorative sheet (5) is adhered to the base material (4) along the longitudinal direction of the wood grain pattern.

After vacuum-pressing the decorative sheet (5) on the surface of the base material (4), the decorative sheet (5) is cut off with a knife or a punching machine at the attaching position of the masking sheet (6). Peel off the masking sheet (6). Thus, as shown in FIG. 3, the face material (3) to which the decorative sheet (5) is not attached is manufactured at the predetermined portion (4A) of the base material (4). The decorative sheet (5
If A) is covered and crimped by vacuuming, a decorative sheet (5A) with a wood pattern along the lateral direction is attached at predetermined places as shown in Fig. 4 Face material of flash door (3) Is manufactured.

Other than this embodiment, the masking sheet (6) may not be peeled off, and the decorative sheet (5A) may be stuck thereon. In this case, the masking sheet (6) does not necessarily have to have releasability, but the decorative sheet (5A)
In the case of vacuum-pressing, the masking sheet (6) is preferably a non-woven fabric having air permeability. The adhesive may be applied to the decorative sheet (5) side.

Another embodiment is shown in FIGS. In this embodiment, the decorative sheet (5A) is adhered to a predetermined portion of the base material (4) of the face material (3) of the flush door by using an adhesive, and the adhesive sheet is further formed on the decorative sheet (5A). A masking sheet (6) is adhered, and a decorative sheet (5) having a pattern different from that of the decorative sheet (5A) is attached to the masking sheet (6) as shown in FIG. It is crimped. After vacuum-pressing the decorative sheet (5), the decorative sheet (5) is cut off at the masking sheet (6) sticking point as shown in FIG. 6, and the masking sheet (6) is peeled off.
Expose (5A).

[0011]

Therefore, according to the present invention, a decorative board material having a partially different surface pattern can be easily manufactured.
