Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flocked decorative board and a method for manufacturing the same.

(Prior Art) In general, a method called flock printing is performed in which short fibers are flocked in a pattern on the surface of a flat material such as woven fabric or paper as a base material.

As an application of this flock printing, a decorative paint layer is formed on the surface of a soft fiberboard substrate, and short fibers are electrostatically flocked partially and patterned on the surface of this decorative paint layer.
-30348) is provided. Although the decorative surface of this ceiling board has an improved design compared to the short fiber pattern in conventional flock printing, the decorative paint layer, the short fibers flocked in a pattern, and their respective color tones are different from each other. The decorative pattern was expressed only through variation, and the design was monotonous and could not be called a luxurious design pattern.

The present invention aims to solve the problems of this type of conventional decorative laminates. That is, as will be described in detail below, in the present invention, the colored adhesive 4 is applied onto the substrate 1 on which the pattern 3 is printed, and then short fibers f are flocked, thereby forming the pattern 3 and the flocked colored adhesive layer 4. This is an attempt to express a decorative pattern with a high degree of design that is a mixture of

Embodiments of the present invention illustrated in the drawings will be described below.

(Description of Examples) ... Optional base treatment 2 is applied to the surface of the plate-shaped substrate 1 as necessary.

The plate-shaped substrate 1 may be an inorganic or organic board such as plywood, fiber board, cement board, silica board, PC board, or a mixed board or composite board of inorganic and organic materials, but is not particularly limited.

Surface treatment 2 is to hide or strengthen the surface of the plate-shaped substrate, or to adjust the surface base such as improving the adhesion of the surface coating film, and includes sealing coating treatment, sealer coating treatment, paper pasting treatment, cross pasting treatment, Refers to undercoating, painting, etc.

... Gravure printing is performed on the surface of the plate-like substrate 1 that has been subjected to the base treatment 2 using a normal printing ink or an ink in which a metal powder pigment is added to the ink.
After printing the pattern 3 using a printing device such as gravure offset printing or offset printing, a drying device is inserted to dry and solidify the pattern coating film.

... Next, using a printing device such as gravure printing or screen printing, the colored adhesive 4 is applied in a pattern in synchronization with or out of synchronization with the pattern 3.

Adhesive 4 is an emulsion type material such as vinyl acetate, polyacrylic acid ester, vinyl acetate acrylic copolymer, vinyl acetate, vinyl chloride copolymer EVA, acrylic vinyl chloride copolymer, synthetic rubber (MBR, NBR, SBR), polyurethane, etc. It is preferable to use one to which a pigment for optional coloring is added.

... Immediately after applying the adhesive 4 in a pattern, the plate-like substrate 1 is inserted into an electrostatic flocking device, and one transparent short fiber f is added to the pattern-shaped colored adhesive layer by the electrostatic flocking method. The short fiber layer 5 is formed by anchoring without gaps and densely flocking. Then, the fibers are pre-dried using a drying device to temporarily fix the flocked short fibers f, and the excess short fibers are collected using a vacuum device. In the electrostatic flocking method, a plate-shaped substrate is transported with its decorative side facing upward, the substrate side is used as a ground electrode, a high-voltage electrode is provided above the substrate, and short fibers f are supplied from above between the electric fields and downward. A down method method in which the short fibers F are flown upward from below by transporting a plate-shaped substrate with its decorative side facing downward, a ground electrode on the substrate side and a high-voltage electrode below it. There are several methods, but any of them is fine.

Short fibers f include human silk, synthetic fibers (nylon, cashmilon, vinylon, corderan, polyester, acrylic, etc.), fabrics, and glass fibers that have been electrodeposited to improve their flight in an electric field. Any material may be used as long as it is transparent (may be transparent).

Although the short fibers f may be twisted yarns, it is preferable to use raw wood in a straight state from which the molten raw material liquid is extruded from the nozzle during the spinning process.

Next, it is inserted into a drying device to solidify the adhesive and fix the short fibers.

...Furthermore, if necessary, apply a transparent top coat 6 to the entire surface.
is applied using a coating device such as a flow coater or a sprayer, and then inserted into a drying device and a top coat 6 is applied.

In this way, a pattern 3 is printed on the surface of the plate-like substrate 1 which has been subjected to an optional base treatment, and transparent staple fibers are printed through the colored adhesive 4 without matching the pattern 3. A decorative board having a short fiber layer 5 formed by dense electrostatic flocking is obtained.

(Effects of the present invention) Colored adhesive 4 is applied in a pattern on the pattern 3,
Since the transparent short fibers f are flocked, the patterned colored adhesive 4 can be seen through the transparent short fibers f, and the pattern of the colored adhesive 4 with the short fibers f flocked is expressed faintly, The flocked part is expressed in a convex shape mixed with the original pattern 3, giving a sense of luxury and improving the design.
