Abstract

(57) [Summary] [Purpose] To manufacture decorative deck materials whose printed patterns are hard to erase. [Structure] A concave pattern 11 is formed by pressing an embossing roll 2 on the surface of a thermoplastic resin deck material 1, and a paint 4 is applied to the concave pattern 11 to form a pattern 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a deck material decorated by printing a pattern such as a pattern on the surface of a thermoplastic resin deck material.

[0002]

2. Description of the Related Art A deck material, which is a long body having a U-shape or a U-shape in cross section, is used as a floor material by arranging them side by side. Many are produced by extrusion molding or the like using a plastic resin as a raw material.

By the way, a deck material made of a thermoplastic resin can be colored in each color by adding a colorant to a raw material resin and extruding the colorant, but a pattern such as a pattern cannot be formed on the surface as it is.

Therefore, in order to form a pattern such as a pattern, a pattern was printed on the surface of a deck material extruded from a thermoplastic resin by using a gravure coater.

[0005]

In the printing method using the above gravure coater or the like, since the ink is applied to the smooth surface of the deck material to print a pattern such as a picture, the printed pattern is printed on a person. There is a problem that the ink is peeled off by being directly stepped on and the pattern is easily erased.

In order to prevent the printed pattern from peeling off or disappearing, it is conceivable to coat it with a transparent resin to protect it, but it requires an additional coating layer forming step, which is troublesome, and the cost increases.

In view of the above points, an object of the present invention is to provide a method for producing a decorative deck material having a printing surface on which a pattern is not easily peeled off or disappeared without coating a transparent resin. ..

[0008]

According to the method for producing a decorative deck material of the present invention, a concave pattern is formed by pressing an embossing roll on the surface of a thermoplastic resin deck material, and a coating is applied to the concave pattern. The above-mentioned object is achieved by this.

The thermoplastic resin deck material is usually continuously formed by extrusion molding, and its cross-sectional shape is the same as that of the conventional deck material. Then, after this deck material is once molded, a concave pattern may be separately formed and ink coating may be performed.
An embossing roll, a gravure coater, etc. may be provided in series, and so-called in-line concave pattern formation and ink coating can be performed continuously with molding of the deck material.

[0010]

In the method for producing a decorative deck material according to the present invention, since a concave pattern is formed on the surface of the thermoplastic resin deck material and ink is applied to the concave pattern, the ink is applied to the outside of the deck material surface. Since it does not protrude toward the side and does not come into contact with people when it is touched by people, the ink does not peel off and the pattern is retained for a long time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The method for manufacturing a decorative deck material of the present invention will be further described below with reference to the embodiments of the drawings.

FIG. 1 is an explanatory view of an example of a method for manufacturing a decorative deck material according to the present invention, in which 1 is a thermoplastic resin deck material, 2 is an embossing roll, and 3 is a coater. The thermoplastic resin deck material 1 is
It is continuously extruded into a predetermined shape, and the surface thereof is continuously sent to the embossing roll 2 in a softened state. Here, the convex portion of the embossing roll 2 bites into the surface of the deck material 1 to form the concave pattern 11. Subsequently, the deck material 1 is sent to the coater 3. The coater 3 includes an application roll 31 having the same convex portion as the embossing roll 2, a measuring roll 32, and the like.
After that, it moves to the convex portion of the coating roll 31 and is transferred to the concave pattern 11 of the deck material 1 to form a pattern 12 such as a picture. In this way, the decorative deck material is continuously manufactured.

[0013]

As described above, according to the present invention, it is possible to easily manufacture a decorative deck material in which the ink is not easily peeled off even if the printed pattern such as a pattern is not protected by the transparent resin coating layer.
