JPS6028725Y2 - Wood edge wrapped decorative board - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a wood-end wrapped decorative board with a smooth wood end portion.

Conventionally, plywood and particles were used as shown in Figure 1.

A decorative sheet 3, which is a thin sheet made of a thermoplastic synthetic resin such as vinyl chloride resin or polyolefin resin, with a pattern etc. printed on a plate-like substrate 1 such as a gypsum board through an adhesive 2, is attached to the wood end portion a of the substrate 1 and There is no problem if the decorative sheet 3 is smooth in the case of a wood end-wrapped decorative board that is integrally rolled and glued to the back side. When the wood ends are rolled to form a decorative board, when these decorative boards are applied one after another with the wood ends in contact (punching construction) as shown in Figure 2, the contact area is neat due to the unevenness of the decorative sheet 3. The construction finish produced by straight lines was unsatisfactory.

Therefore, in this invention, a decorative sheet 3 is placed on the surface of a rectangular plate-like substrate 1.
To provide a wood end-wrapped decorative board in which the decorative surface is embossed and the wood end portion a is made of a smooth decorative sheet 3 in which the decorative sheet is integrally rolled and bonded to the wood end portion a and the back side. As a result, when the wood is pressed against the wood as shown in Fig. 3, the wood end portions a are completely in contact with each other, resulting in a clean, straight and beautiful finish.

Note that 4 in the figure indicates a stud.

The plate-shaped substrate 1 that can be used in the present invention is plywood.

Examples include wood-based materials such as particle board and birdboard, and inorganic materials such as slate, plasterboard, and pulp cement board.

The thickness of the synthetic resin sheet 3 is 0.03rIn to 0.3
Examples include sheets of thermoplastic synthetic resin such as vinyl chloride resin or polyolefin resin, which are embossed with satin finish of rIrrfL level, cloth grain, and pipe grooves, etc., and which are printed with a pattern.

The emboss straightening method for the decorative sheet 3 can be carried out by applying heat and pressure using a roll press or a flat press, either before applying the decorative sheet 3 to the substrate 1 or after applying it to the substrate 1 to form a decorative board. The heating and pressing conditions must be selected depending on the type of synthetic resin of the decorative sheet 3 used, the depth and size of the embossing, etc.

Note that the decorative sheet 3 on the back surface of the substrate 1 may or may not be embossed.

Next, examples of the present invention will be described.

Example 1 A pattern was printed on a vinyl chloride sheet with a thickness of 0.075 mm and a width of 67 mm, and then a texture embossing process with a depth of 300 to 400 μm was applied to the entire surface of the sheet to obtain a decorative sheet.

Subsequently, after applying 80 fl/- of ethylene resin-modified vinyl acetate resin adhesive 2 to the back side of this decorative sheet, a thickness of 7
They were stacked on a plywood surface with a width of 9 and a width of 610 mm.

Next, a decorative sheet was attached to wrap the plywood from the end of the wood to the back side, creating a decorative board wrapped around the wood end.

Furthermore, this wood edge-wrapped decorative board is placed between five heating rolls that are placed so as to sandwich the wood end portion of the decorative board from the left and right.
A wood edge-wound decorative board with smooth wood edges was obtained by passing the wood through a temperature of 120 to 150°C.
