Abstract

(57) [Abstract] [Purpose] A flooring material whose surface is decorated with a beautiful pattern rich in natural feeling without the need for post-processing such as printing, attaching synthetic resin film, and painting. provide. [Structure] Upper surface 5 of floor material body 1 made of extruded synthetic resin
Further, the wood powder 4 is embedded and fixed by crimping in a sprinkled state.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor material made of synthetic resin whose surface is decorated.

[0002]

[Prior art]

 Conventionally, as a method of decorating the surface of a synthetic resin floor material, direct gravure printing is applied to the surface of the floor material, or a synthetic resin film with a pattern printed in advance is attached to the surface of the floor material. Is being done.

Further, a resin coating material containing inorganic particulate matter (eg, silica, silica sand, etc.) insoluble in acrylic resin coating material is applied and dried on at least the upper surface of the deck material main body made of vinyl chloride resin, and the unevenness is obtained. Japanese Patent Laid-Open Publication No. 57-321197 is disclosed.

However, since the flooring materials obtained by the above method are all decorated with an artificial pattern, they have a poor natural sensation. Furthermore, after the flooring materials are molded by extrusion molding or the like, they are decorated. In addition, there is a drawback in that post-processing steps such as printing, sticking of synthetic resin film and painting are required.

[0005]

[Problems to be solved by the device]

 The present invention has been made in view of the above drawbacks, and its purpose is to have a natural surface without requiring post-processing steps such as printing, attaching a synthetic resin film, and painting. The purpose is to provide flooring that is decorated with beautiful patterns.

[0006]

[Means for Solving the Problems]

 The flooring material of the present invention is characterized in that it is embedded and fixed by crimping in a state in which wood powder is scattered on the upper surface of a flooring material main body made of an extruded synthetic resin.

Hereinafter, the present invention will be described in detail. The material of the flooring material main body is not particularly limited, but examples thereof include hard vinyl chloride, ABS resin, FRP and the like.

The flooring material main body is formed by an ordinary extrusion molding method using an extruder. The wood powder is sprayed on the floor material main body while the floor material main body is in a molten or semi-molten state immediately after being extruded from the mold, and the sprayed wood powder is pressure-bonded by a roll or the like. Thus, it is embedded and fixed on the floor material main body.

The grain size of the wood powder is preferably such that it passes 20 mesh and 80% of 40 mesh remains without passing. The water content of wood flour is preferably 20 to 30% by weight.

Further, it is preferable that the wood powder is sprayed so as to cover 5 to 10% of the upper surface area of the flooring body.

[0011]

[Action]

 The floor material of the present invention has wood powder sprinkled on the upper surface of the floor material and is embedded and fixed by crimping, so the surface can be decorated with a beautiful pattern with a natural feel, and it also has a non-slip effect. Antistatic effect is imparted.

[0012]

【Example】

 Embodiments of the present invention will be described below. (Embodiment 1) FIG. 1 is a perspective view showing an embodiment of the flooring material of the present invention, in which a flooring material body 1 extruded from a hard vinyl chloride resin is extended in the longitudinal direction. The hollow portion 2 is in the shape of a rectangular tube divided into two chambers by a partition wall 3. While the flooring body 1 was extrusion molded at a resin temperature of 180 ° C. and kept in a molten state, wood powder 4 was sprinkled so that 8% of the area of the upper surface 5 was covered. Then, the floor material main body 1 is passed between a pair of pressing rolls (not shown), and the wood powder 4 is pressure-bonded to be embedded and fixed, so that the upper surface 5 of the floor material main body 1 can be naturally sensed. A floor material decorated with a beautiful pattern was obtained.

When the above floor material was laid on a concrete floor and walked on it, there was no slippage and no static electricity was generated.

[0014]

[Effect of device]

 Since the flooring material of the present invention is configured as described above, it is decorated with a beautiful pattern of natural feeling, and there is no slippage even when walking on it, and no static electricity is generated. Also, wood powder is sprinkled on the upper surface of the extruded floor material body and fixed by embedding by pressure bonding, so the surface is decorated with a beautiful pattern with a natural feel without requiring complicated steps. can do.
