Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative laminate whose surface is flocked with staple fibers, and its manufacturing capacity and performance.

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

Short fibers are electrostatically flocked partially on the surface of the decorative paint layer in a pattern a'' to create one sound-absorbing decorative ceiling board (Utility Model Publication No. 46-30348).
) are provided.

Although the decorative surface of this ceiling board has a lower design compared to the short fiber pattern in conventional flock printing, it is made up of a decorative paint layer, short fibers flocked in a pattern, and their respective color tones. The design was based on changes and was not completely satisfactory.

The object of the present invention is to solve the problems of a decorative board in which short fibers of this type are flocked. That is, as will be described in detail below, the non-invention is to apply a transparent adhesive 4 on a substrate l on which a pattern 3 is printed.
After applying, pattern pattern 3 is created by flocking short fibers f.
is expressed in whole or in part in a light manner in an attempt to improve the design effect.

(Description of Implementation Example 11) The implementation of the present invention shown in the drawings will be described below.

First, the first implementation column shown in FIG. 1 will be explained.

(2)... Optional base treatment 2 is applied to the surface of the plate-like substrate l as required.

The plate-like substrate 1 is plywood, fiberboard, or cement board.

Any inorganic board such as a silica board or a PC board, an organic board, a mixed board of inorganic and organic materials, or a composite board may be used, and there is no particular limitation. Surface treatment 2 is to adjust the surface of the plate-shaped substrate 1 by concealing it, strengthening it, or improving the adhesion of the surface coating, such as sealing coating, sealer coating, paper pasting, and undercoat coating. means.

■・・・Next, the surface of the plate-shaped substrate 10 that has been subjected to the base treatment 2 is coated with ordinary printing ink, and then gravure printing and gravure offset printing are performed using an ink in which a metal powder pigment is added to the ink. , print and form the pattern 3 using a printing device such as offset printing,
Insert into a drying device and dry and solidify the patterned coating.

■・・・Next, using a printing device such as gravure printing or screen printing, the adhesive 4 that becomes transparent or becomes transparent by drying and solidifying is printed in a pattern with or without synchronization with the pattern. Apply. Adhesive thickness] 4 includes vinyl acetate, polyacrylic acid ester, vinyl acetate acrylic copolymer, vinyl acetate vinyl chloride copolymer, (EVA), synthetic copolymer of acrylic vinyl chloride copolymer (MBR, NBR, SBR,), polyurethane, etc. The emulsion type is better.

■-・・・・・・ After applying adhesive 4 in a pattern, immediately insert the plate-shaped substrate into an electrostatic flocking device, and remove the adhesive in a pattern by electrostatic flocking.
Transparent short fibers F are anchored one by one without any gaps in the can and flocked into the can to form a short fiber layer, and then pre-dried using a drying device to temporarily fix the flocked short fibers F, and then vacuumed. Excess short fibers are collected by a device.

In the electrostatic flocking method, a plate-shaped substrate 1 is transported with its surface facing upward, a ground electrode is provided on the substrate side, and a high voltage electrode is provided above it, and the short fibers f are supplied to an electric field from above and flown downward. There is a down method method, or an up method method, in which a plate-shaped substrate is transported with its surface facing downward, the board electrode 1 is used as a ground electrode, a high voltage electrode is provided below it, and the short fibers F fly from below to above. But it's okay.

Short fibers include human silk and synthetic fibers (nylon).

Casimiro, N, Hiniron, Coplan, Polyester,
Any material that is transparent (it may be colored and translucent), such as acrylic (acrylic, etc.), or glass fiber that has been electrodeposited to improve its flight in an electric field. But that's fine.

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

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

■・・・・・・Additionally, if necessary, apply a transparent top coat to the entire surface using a coating device such as a flow coater or sprayer.After 1 coat,
Insert into drying equipment and apply top coat.

A pattern 3 is printed and formed on the surface of the root-like substrate l which has been subjected to an arbitrary base treatment 2 in the manner shown in σ), and is then coated with a transparent adhesive 4 in synchronization with or without synchronization with the pattern. A decorative board having a short fiber layer formed by densely flocking transparent short fibers f can be obtained.

(2) Although the above description has been made regarding the case where the short fiber layer 5 is partially provided, the transparent adhesive 4 and the transparent short fiber layer 5 may be provided on the entire surface of the substrate 1 on which the pattern 3 is printed. In this case, the entire pattern 3 is expressed with a light texture and deep unevenness, giving it an elegant feel.

(Effects of the present invention) A transparent adhesive 4 is applied on the pattern 3, and the transparent short fibers f are flocked to the transparent adhesive 4, so that the transparent short fibers f
, the pattern 3 can be seen through the adhesive 4. Therefore, when the adhesive 4 is not in sync with the pattern 3, a part of the pattern 3 will appear pale, and the short fiber layer 5 will have a convex shape, allowing the uneven pattern and shading pattern to be expressed gracefully.

Furthermore, when the adhesive 4 is applied to the pattern 3 or applied to the entire surface, the entire pattern 3 appears pale and uneven, adding an elegant feel.
