Description

TECHNICAL FIELD The present invention relates to a floor structure having non-slip durability.

(Prior Art) Conventionally, a flooring material having a smooth surface is slippery when the surface is wet with water, oil, or the like, which poses a danger in walking and running of a vehicle.
Therefore, a floor material (floor structure) having an anti-slip function was studied. They are, for example, those obtained by mechanically embossing the surface, burying small sand or granular particles only in the surface layer, or randomly mixing variable or compressible elastic rubber particles in the composition. It was

The present invention belongs to the technical field of providing unevenness on the surface among these examples. Among them, the finish of the floor may be a coating material or a tension material. Examples of the related arts disclosed are JP-A-62-63759, JP-A-61-242256, and JP-A-57-143058. Among these techniques, ceramic materials, small sand, water-absorbent resin granules, etc. have been used as materials for forming projections for increasing frictional resistance.

(Problems to be solved by the invention) However, the ceramic material or small sand for forming projections, which has been frequently used in the past, has high hardness but is brittle, and often cracks due to passage of heavy objects or impact. . In addition, even if it is not cracked, it is generally rounded and square, so that it is easy to make the coating film covering these particulates uneven in thickness, and it is easy to make scratches on the coating film due to abrasion. Therefore, one of the objects of the present invention is to make a material that does not crack. The other is that the water-absorbent resin granules, which are the material for forming projections, have poor wear resistance, and even when they become projections containing water, they deform or release water when pressure is applied, and non-slip. There was a problem with sex.

(Means for Solving Problems) In the present invention, as means for increasing the frictional resistance of the floor,
The projections are scattered. To provide a protrusion. It is said that the coating composition contains particles and is applied at once, or a first coating layer is provided in the form of sandwiching the particles, and when the raw material is in a dry state, the particles are sprayed and the coating is further applied onto it. There is a way. The resulting floor structure itself has a large number of scattered protrusions formed by the granular material covered with the paint layer on the floor surface. The granular material that is a feature of the present invention includes polyethylene, polypropylene, nylon, polyurethane, polystyrene, polycarbonate, acrylite, polyester, polyvinylidene chloride, vinyl chloride resin, vinyl acetate resin, ABS (acrylonitrile-butadiene-styrene) resin. , AS (acrylonitrile-styrene) resin, and copolymers thereof.
Generally, thermoplastic resin is good, particle size of particle is 1-4mm
If it is smaller than this, the effect of the particulate matter covered with the paint layer as a protrusion for preventing slip is small, and if it is larger than 4 mm, it becomes easy for dirt and dust to enter and stain easily. There is. The amount of the particulate matter mixed in the paint is preferably 1% to 50% by volume. When this ratio is small, the projections due to the particulate matter are sparse when applied to the floor and the anti-slip effect is not obtained. On the other hand, if the proportion is too large, the amount of coating material that covers the particulate matter decreases and the durability deteriorates.

(Operation) In the present invention, the granular material made of a material which is not easily broken serves as a projection which serves as an anti-slip function. The paint layer covering the particulate matter serves as a protective layer for the particulate matter and a fixed layer for the particulate matter.
Then, even when the paint layer on the protruding portion is worn away, at this time, the difference in friction resistance between the paint portion and the granular material functions to prevent slippage.

(Example) The present invention was carried out by performing a trial installation on a factory floor where a truck with steel wheels is coming and going. Example 1
In Nos. 2 and 2, it was used in the form of mixing granules in the paint.
The composition was 100 vol of polystyrene granules (particle diameter 2-3 mm) for Example 1 to 100 vol of reaction-curable urethane resin coating (for soft floor), and polystyrene granules of Example 2 (particle size 1 ~ 2mm) For 10vol,
The reaction curing type epoxy resin paint (for floor) was 100 vol.
In Example 1, a moisture-curable urethane primer was used.
It was first coated with a coating amount of 1 kg / m ² . In addition, in Example 3,
A reaction-curable urethane resin paint (for hard floor) was once applied to the floor, and immediately after that, ABS resin particles (particle diameter 3 to 4 mm) were sprayed, and the urethane resin paint was applied thereon again. The approximate volume ratio at this time was 1: 2 for the particulate matter and the paint. In the comparative example, 50v of the conventional method of silica sand 2-3 mm (No. 2 silica sand phase etc.)
For ol, reaction-curable urethane resin paint (for soft floors) 10
The mixture was painted at a ratio of 0 vol. Regarding the coating amount, the synthetic resin paint excluding the particulate matter was applied at 1.5 kg / m ² .

Then, after observing the construction site after half a year, in Examples 1 to 3, the coating film at the tip of the convex portion of the portion containing the particulate matter was worn away and there was no destruction of the granular body. It was On the other hand, in the comparative example, abrasion of the coating film and crushing of the silica sand contained in the coating film were observed, and dust was generated.

(Effect) According to the present invention, there is an effect of changing a floor structure, which has conventionally lost the function of preventing slipping during heavy walking, to a durable one.
