Abstract

PROBLEM TO BE SOLVED: To obtain non-slip performance by embedding inorganic transparent glass solid spheres in a transparent resin paint film formed on the surface of a wood floor plate base. SOLUTION: A thin wooden plate and a decorative printed sheet are stuck to the surface of wood plywood to form a wood floor plate base 1, and resin moderately flexible and transparent after solidification is applied to the surface of the wood floor plate base 1 by painting or the like to form a transparent resin paint layer 2. Inorganic transparent glass solid spheres 3 with a diameter approximate to the thickness of the paint layer 2 are further contained in the transparent resin paint layer 2, and these spheres 3 are placed in the state of being embedded in one layer in the thickness direction of a paint film, close to one another so as to obtain a non-slip floor plate with the fine uneven surface generated by load such as walking.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden floorboard having a suitable non-slip performance and excellent durability.

[0002]

2. Description of the Related Art Floor boards often used in the field of interior construction are
Wood floorboards are often used due to the design and texture of the wood, and the surface is generally coated with a transparent paint in consideration of stain resistance, durability, and aesthetics. This surface coating naturally emphasizes transparency and coating strength that does not easily scratch, so aggregates and fillers that do not impair transparency can be mixed and used in a transparent coating, or the coating resin itself is relatively hard and strong. The one with the highest price is used. In addition, there is also a part where a transparent hard aggregate of irregular size is exposed on the surface of the coating film to prevent slippage.

[0003]

[Problems to be Solved by the Invention] Considering improvement in durability and aesthetics maintenance performance, further hardening and thickening of the coating film are inevitable, resulting in slipperiness and accidents such as falls. It is easy to do. In order to prevent this slipping, of course, there is a painted floorboard with a small amount of irregular hard aggregate exposed on the surface of the paint film, but it can cause scratches when socks or stockings are normally walked, and scratches when falling. It cannot be avoided. The surface condition also reduces the ability to remove contaminants.

From these circumstances, there is a demand for a wood-based floorboard having a flat surface and having excellent transparency and durability, high coating strength essential for maintaining aesthetics, and appropriate non-slip property. is.

[0005]

Means for Solving the Problems The present invention has been invented to solve the above problem, and will be described with reference to the drawings. The transparent flooring substrate material (1) having an appropriate flexibility is provided on the surface thereof. A resin coating layer (2) is formed, and inorganic transparent glass solid spheres (3) having a diameter close to the coating layer thickness are made to be close to each other in the transparent resin coating layer and one layer is formed in the coating thickness direction. It is a coating film composition that is embedded side by side.

[0006]

According to the coating film structure of the present invention, the resin portion which is normally flat and has flexibility when subjected to a load such as walking causes a dented concave deformation, but the solid glass spherical portion does not deform and is convex. When the load is removed, the flexible resin portion of the concave portion recovers and returns to a flat surface. In other words, when walking, the load creates a fine uneven surface, and exhibits appropriate non-slip properties.

The inorganic solid glass spheres themselves have high pressure resistance and high strength, and effectively dissipate the force from the shape. To form it, the force is dispersed and received at the same time by a large number of glass spheres against impact and wear. In addition, unlike other deformed hard aggregates, because it is an excellent spherical body, it is less likely to cause internal fracture of the coating from the glass ball contact part in the coating against external load, resulting in strength and wear resistance. And it forms a coating film with excellent durability.

Since glass spheres are spheres, their volume is the largest among all shapes and by embedding them in the coating film, most of the coating film will be replaced by glass. Glass is a material that is extremely stable and does not easily discolor and fade, and reducing the amount of resin in the coating also reduces the discoloration and discoloration of the coating. In addition, the optical performance of the glass sphere is a large light refraction effect. Gives an excellent three-dimensional and depth feeling to the paint film.

Since most of the other coatings are glassy, the flammability is greatly reduced compared to coatings using resin alone, and coatings with excellent safety, which are strongly desired for interior material applications, can be obtained. It is possible.

INDUSTRIAL APPLICABILITY As described above, the wood-based floorboard obtained according to the present invention has epoch-making non-slip performance, remarkably excellent durability, aesthetic maintenance ability and safety, and a coating film-forming coating material. It is very economically and economically useful in terms of volume reduction.
