Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a flooring material.

[0002]

2. Description of the Related Art The floor material referred to here is a floor structure that is placed on a concrete foundation or the like and may be indoors or outdoors. Hereinafter, the floor material laid on the balcony or the balcony of the building will be described as an example, but the floor material is not limited thereto. The veranda is usually made of concrete, which is not only aesthetically pleasing, but also lacks water permeability, so water accumulates on the surface. Of course, the water is allowed to escape to the gutter by inclining it, but it is certain that the surface water also remains.

In order to prevent these problems, it may be possible to adhere the floor material to the balcony according to the dimensions. However, this cannot be done by an amateur, so it is expensive and
Once installed, replacement is not easy.

Therefore, a flooring material having a predetermined size has been developed, which an amateur only needs to place. For example, 30 × 3 artificial grass
A floor material can also be cut into a size of about 0 cm. In this case, it suffices to mount a large number (a predetermined number) of small floor materials having the predetermined size, which is simple. In addition, because it has the appearance of natural grass, it has an excellent aesthetic appearance and was once widely used.

[0005] In addition to this, there is one in which a tile or a wooden board is attached to a water-permeable base material having a predetermined standard size. These are aesthetically pleasing and are easy to install because they are also simply placed.

[0006]

However, these floor materials have the following drawbacks. Since tiles and wooden boards are not water-permeable, they have joints and drainage from them. In such a structure, moisture will definitely stay on the tile surface and the wood surface,
It slips. In addition, in the case of artificial grass, dust and the like are clogged around the root of the artificial grass, and it decomposes and gives off a bad odor, and becomes a home of mites and the like.

[0007]

In view of the above circumstances, the present inventor has completed the flooring material of the present invention as a result of earnest research, and is characterized in that it has a water-permeable base material. A resin plate is attached to the resin plate, and the resin plate is characterized in that a material obtained by mixing the aggregate and the resin in a water-permeable ratio is cured into a plate shape.

The resin plate is a plate-shaped material obtained by mixing an aggregate and a resin in a water-permeable ratio. Any aggregate or any resin may be used as long as it has water permeability and can withstand walking. As the resin, an epoxy resin, a urethane resin, an acrylic resin, or the like is suitable.

As the aggregate, stone, ceramic, glass,
Any material such as plastic or rubber can be used.
These aggregates are preferably aesthetically colored aggregates. Further, various colors may be mixed, or the patterns may be divided and cured. Further, by using a plurality of aggregate colors, granite or marble may be used.

Any size of aggregate may be used as long as water permeability can be secured. However, in particular, the particle size distribution of the aggregate may be within the following range. (1) 60-90% by weight of aggregate with a particle size of 1.5-0.4 mm, (2)
10-40% by weight of aggregate with a particle size of 0.4 mm or less. That is, the present inventor mixes a large aggregate of 0.4 mm or more with 60 to 90% and a small aggregate of 0.4 mm or less with 10 to 40%, and has a good balance between the water permeability function and the clogging prevention function due to dust, It was found that the water flow was secured and it was difficult to be clogged. The reason is that it was found from experiments that the size of general clogging substances (sand, dust, etc.) was 0.1 to 0.2 mm. If the large aggregate is 90% or more, the filtering effect becomes small. Also, if the small aggregate is 40% or more, the water permeability is reduced.

Further, the following particle size distribution was more suitable for the particle size distribution of this aggregate. (1) 30-50% by weight of aggregate with a particle size of 1.5-0.8 mm, (2)
Aggregate with a particle size of 0.8 to 0.4 mm is 30 to 50% by weight, (3) Particle size is 5 to 15% by weight of aggregate with a particle size of 0.4 to 0.2 mm, (4) Particle size is
2 to 15% by weight of aggregate of 0.2 mm or less. Among these, (1)
Aggregate with a particle size of 1.2-0.8 mm is 35-45% by weight, (2) Particle size is 35-45% by weight with an aggregate of 0.8-0.4 mm, (3) Particle size is
7 to 15% by weight of 0.4-0.2mm aggregate, (4) 0.2m particle size
2-10% by weight of aggregate of m or less. Was preferred.

The consideration of such particle size distribution is based on the following reasons. If it is just water permeability, it is better that the aggregate is large and there is no such thing as 0.4 mm or less. However, the point is to insert fine aggregate, which prevents clogging due to fine dust.
Further, even with this, sufficient water permeability can be exhibited.

The thickness of the resin plate is about 5 to 30 mm, more preferably 10 to 15 mm. The size is not limited as long as it matches the substrate.

In the case of stone aggregate, the mixing ratio of resin and aggregate is 200 to 10 with respect to 100 parts by weight of resin.
About 100 parts by weight is suitable. However, it is premised that it has water permeability. Naturally, the lower the specific gravity of the aggregate, the less the weight of stone is.

It goes without saying that the resin may be mixed with what should be usually mixed in addition to the aggregate. For example, pigments, fragrances, germicides and surfactants may be mixed. This is because mixing a surfactant improves water permeability.

The base material is a lower layer of the above-mentioned resin plate and also serves as a support thereof, and may be any material having water permeability. The material is preferably plastic, but may be wood, metal, or the like. Also, a type with a large number of legs, such as a babyshed, is preferable.

Further, it is preferable that this base material has a connecting tool so that adjacent bases can be connected to each other. For example, it may have a large number of insert pieces and receiving portions on its sides.
