Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a highly productive and beautiful three-dimensional decorative laminate manufacturing method.

Conventionally, decorative laminates for interior use include natural wood veneer veneers,
There are many special plywoods such as printed plywood and decorative boards made of inorganic boards, and one way to give them a three-dimensional effect is to apply a sheet material to the surface of a plate-like base material with an uneven pattern using a vacuum press method. There was a method to do this, but the productivity was extremely low and it was too expensive, so it was not widely used as a housing interior material.

The present invention has been made in view of the above-mentioned points, and provides a method for manufacturing a decorative board that is highly productive, inexpensive, and has a beautiful three-dimensional effect.

In the manufacturing method of the present invention, first, the surface of a plate-shaped base material such as plywood, fiberboard, particleboard 1/9, gypsum-slag board, or calcium silicate board is coated with an appropriate method such as press molding or cutting. Four grooves are formed, and then flexible sheets such as printed paper, vinyl chloride decorative film, olefin M decorative film, etc. are continuously adhered to these surfaces using an adhesive. Press roll t: A continuous laminator, which is a rubber sponge roll, is used to produce a three-dimensional decorative board.

There is no particular limit to the depth of the four-strip groove, but it is usually 1 @
It is around /n. If the board is made of 3-ply plywood, only the front veneer (usually about 1.n/, n thick) should be 7 l f
'411-It is necessary to make the concave grooves by one cedar; in particular, if the depth of ljG is made completely shallow, it will also prevent a decrease in the bending strength of the board, so the depth of the grooves should be Approximately 0.6 m/m is appropriate.

Conventional continuous λ set 1; laminator has 1 press roll
~12 rolls were equipped, but these rolls were made of metal or its surface II wrapped with 10 to 20, n/, n of synthetic rubber. When a sheet was adhered to a plate-like base material with four grooves formed thereon, it was hardly adhered to the concave f%. The continuous laminator used in the present invention is as described above, and is capable of pasting sheets along the four-striped grooves and without wrinkles. This is an example showing a state in which a continuous laminator is used to adhere a sheet to a plate-shaped handle material with four grooves formed therein. This shows a state in which a flexible sheet 3 coated with adhesive by a coating machine 2 is first pasted with a rubber sponge roll 4 and then with a gold paste roll 5.

The adhesive may be applied to a plate-like base material.

The rubber sponge roll may be one in which a rubber sponge is wound on the surface of a metal roll at a rate of 3 to 10 ITl/nn PA, and as the rubber, urethane-based, ethylene-propylene thread, or nitrile-styrene reppolymer-based rubber can be used. . The thickness of the rubber sponge depends on the depth of the four-striped groove, but the depth of the groove is 05 to 2.
If the thickness of t is 4 to 10 m/rn, the sheet can be stuck sharply along the groove, and if it is thicker than this, it will adhere to the bottom of the four-striped groove. The appropriate hardness of the rubber sponge is 20 to 40 degrees.

As claimed in claim 2, when the width of the four grooves formed on the surface of the plate-like base +2 is equal to or larger than lOω/lln, and the area force of the four grooves is 1/2 to 1/10, a striped pattern can be obtained. A decorative board with an extremely rich three-dimensional effect can be obtained.

When using a vinyl chloride resin film as a flexible sheet, the amount of plasticizer used should be 10 to 10% from the viewpoint of flexibility.
30%, preferably 20-25%, and the sheet thickness is preferably 100P or less. Since it has all the hollow ￥tll, it can be easily formed into a short shape by outside + 1>, and it goes well with concave / ii &: 'j? ?

A three-dimensional striped decorative board was obtained by applying pressure using a continuous laminator and then pressing with a chrome-plated metal roll.

All four convex parts of the decorative board did not cause any wrinkles on the decorative paper and were in close contact with the board, and a force of 11 was applied at a speed of 40 m/'mth.
