Abstract

(57) [Summary] [Purpose] To provide a decorative deck material having a pattern rich in natural feeling other than a flow pattern. [Constitution] Natural product strip 2 is made of rigid vinyl chloride resin raw material 1
The mixed raw material added to about 20 parts by weight with respect to 00 parts by weight is extruded and molded by an extruder provided with a die having a resin passage having a cross-sectional shape of the deck material 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a decorative deck material made of synthetic resin whose surface is decorated.

[0002]

[Prior Art]

 The deck material, which is a long body with a U-shaped or square-shaped cross section, is used as a floor material by arranging them side by side, but it is made of hard synthetic resin such as hard vinyl chloride resin. Many of them can be manufactured by an extrusion molding method or the like.

By the way, an extrusion molded body of a hard synthetic resin can be colored in various colors by coloring and extruding a raw material resin, but it is difficult to manufacture a molded body having a patterned surface. It is known that a slightly different coloring material is mixed into the raw material resin and a pattern is formed on the surface of the molded product due to the difference in the flow of both materials during extrusion.

[0004]

[Problems to be solved by the device]

 Since the deck material obtained by the above method utilizes the difference in the flow of both materials during extrusion, the pattern is limited to the flow pattern. Therefore, in order to obtain other patterns, a complicated process such as attaching a printing film separately or performing gravure printing on the surface of the molded body is required. Moreover, the printed pattern produced by this method was not natural.

The present invention has been made in view of the above points, and an object thereof is to provide a decorative deck material having a pattern rich in natural feeling other than a flow pattern.

[0006]

[Means for Solving the Problems]

 The decorative deck material of the present invention is characterized in that the natural product strips are partially exposed and embedded in the surface of the synthetic resin molded body, thereby achieving the above object.

As a method for manufacturing the decorative deck material, for example, a method in which a synthetic resin is mainly used, and a material obtained by mixing the natural product fine particles therein is molded by extrusion molding or the like is preferably adopted. According to this method, a part of the natural product fine particles is dispersed on the surface portion of the molded body, and a pattern is developed by partially exposing it. In this case, the amount of the natural product particles added is determined in terms of moldability and the pattern to be obtained, but is generally 5 to 20% by weight.

[0008] Examples of the natural product flakes include natural products such as stones and wood, and the size and shape thereof are not particularly limited, but in the case of an extrusion molding method, the moldability thereof is not impaired. It has a size and shape. Here, two or more kinds of natural product strips to be used may be used in combination, or those having different sizes and shapes may be used in combination. This gives the deck material a variety of patterns.

[0009]

[Action]

 In the decorative deck material of the present invention, the natural product strips are partially exposed and embedded in the synthetic resin molded product, so that a pattern rich in natural appearance is developed.

[0010]

【Example】

 The decorative deck material of the present invention will be further described below with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view of an embodiment of a decorative deck material of the present invention, 1 is a deck material, and 2 is a small piece of natural product.

The deck material 1 is a mixed raw material obtained by adding about 20 parts by weight of a natural product strip 2 of 1.0 to 3.0 mm angular sand to 100 parts by weight of a hard vinyl chloride resin raw material. The material 1 was extruded from an extruder equipped with a die having a resin passage having a gap of 4.0 mm in the cross-sectional shape and molded. By this extrusion molding, the natural product strips 2 are dispersed in the molded body and at the same time, a part thereof is partially exposed on the surface to give a pattern.

Thus, the exposed portions of the natural product strips 2 are irregularly arranged, and the exposed state of the surface of the natural product strips 2 also has various sizes, giving a natural appearance. .

[0013]

[Effect of the device]

 As described above, since the decorative deck material of the present invention is patterned with the natural product strips, a separate step of printing or attaching a pattern sheet is not required. In addition, since the pattern is made of natural products, it has a rich natural feel.
