Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flooring material, and more particularly, to a laminated structure in which wood (including plywood), ceramics (porcelain), brick or tile is used as an upper part, and waste rubber or waste plastic is used as a lower part. The present invention relates to a floor material laid on the ground or the like around a children's playground equipment such as a slide, for example.

[0002]

2. Description of the Related Art Generally, soil around children's playground equipment such as slides and swings in a park or the like is compacted due to the lawn being peeled off or sandy ground being blown by wind. . If a child falls on such a ground, it is dangerous not only that the clothes are soiled but also that the head is hit.

[0003] In addition, the danger of falling down is not eliminated by simply laying bricks on the ground, and when laying only wooden flooring, it is not only slippery, but also increases the danger of falling down, and also drains water. However, there is a problem that the floor material is corroded at an early stage.

In addition, waste tires, waste plastics, and the like, which are enormously discharged, have a serious social problem because of the generation of harmful substances such as dioxygen due to incineration.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to prevent injuries such as bruising, etc., even if a child or the like hates falling. It is another object of the present invention to provide a floor material that can be drained well.

It is another object of the present invention to provide a floor material that can be effectively reused such as waste tires and waste plastics.

[0007]

According to the present invention, a flooring material (main flooring material) according to the present invention includes an upper portion made of wood (including plywood), ceramics (porcelain), brick or tile, and waste material. It is characterized by being integrally laminated with a lower portion made of rubber and / or waste plastic.

In the flooring material, at least a part of the lower portion is slightly protruded above the upper portion, and the protruding portion is used as a non-slip for walking, and the protruding portion reduces the impact when falling. Can be done.

The place where the floor material is laid is mainly grounds such as parks, especially grounds around children's playground equipment, but is not limited thereto. Aisles, offices, etc. are also included in the scope of use.

As the wood, for example, those having high corrosion resistance such as wrapping materials (Finland ferns and the like) produced in Northern Europe can be preferably used. Alternatively, plywood may be used. When used indoors, soft cedar is used. , Pine etc. are desirable,
It may be hardwood. In the case of indoor use, the lower portion made of waste material absorbs and eliminates the walking sound and the like generated by the upper portion of the wooden material, so that, for example, the sound insulation to the lower floor is improved.

The "lower portion made of waste rubber and / or waste plastic" is defined in Japanese Patent Application Laid-Open No.
No. 53320, which corresponds to “porous rubber (layer)”, for example, after mechanically crushing waste tires to remove organic fiber cords, metal cords and the like as tire reinforcing materials. Crushed rubber (average maximum particle size 0.2-25
mm (see FIG. 2 (a) of the same publication)) and a binder (Coronade 2011 or the like manufactured by Nippon Polyurethane Co., Ltd.) is mixed, and then the crushed rubber is heated and pressed in a mold. It can be composed of a compression molded body of required dimensions. The “porous rubber (layer)” having undergone such a process has continuous pores having excellent air permeability (see FIG. 2 (b) of the same publication).
Thus, the "lower portion" is porous and has good water permeability.

In the production of the floor material, the above-mentioned crushed rubber or the like can be introduced after the wooden plate material or the like is housed in the mold, and the upper portion and the lower portion are bonded together with an adhesive or the like. Crimping is also possible.

In the present invention, as the raw material of the "lower portion",
In addition to the above vulcanized rubber such as waste tires, waste plastics such as PET bottles, agricultural vinyls, plastic packaging materials, and synthetic fiber materials can be used. When fiber materials are mixed, fibers are mixed in a net shape. However, the strength of the lower portion against rupture can be enhanced.

It is desirable that the projecting height of the projecting portion in the lower portion is such that it does not hinder walking, specifically, it is desired to project about 0 to 5 mm from the surface of the upper portion. The set number and the like can be set as appropriate.
