Abstract

PURPOSE:To enable coating to be uniformly achieved, while the abrasive resistance of floor material, and the dispersion and operational property in a coating process are improved by a method in which the surface of a wooden base late is coated with the coating containing powder resin wax, thereby making a coating layer. CONSTITUTION:The wooden base plate 1 is constituted by sticking a wood veneer 4 to the surface of a plywood 3. Sanding is applied to this wood veneer 4, and said veneer is coated with the coating compounded with powder resin wax. Next, sanding is applied to the surface of a formed coating layer 2, and the surface of said layer 2 is coated with the coating containing no powder resin wax, whereby a surface coating layer 5 is formed. Thus, the wooden floor material A is obtained. The abrasive resistance of the surface of this wooden floor material A, as the floor material for one's shoes on, is equal to that of the conventional wooden floor material made by packing inorganic material.

Description

[Detailed description of the invention] 【Technical field】

The present invention relates to a wooden flooring material with excellent wear resistance.

[Background technology]

Traditionally, for example, wood flooring materials with excellent wear resistance have been manufactured by coating the surface of a wood substrate with a paint prepared by blending an amino alkyd resin liquid with an inorganic filler such as silicon carbide or white alumina. However, since the specific gravity of the inorganic filler to be blended is large, the inorganic filler precipitates during the coating process, resulting in a difficult reduction in the workability of the roll coater or 70-coater.
Particularly with roll coaters, uniform coating was not possible, leading to variations in the quality of the wood flooring.

[Purpose of the invention]

The present invention was made in view of the above circumstances, and its purpose is to provide not only excellent wear resistance but also good workability in the painting process and uniform painting. The purpose of the present invention is to provide wooden flooring materials with small variations in quality.

[Disclosure of the invention]

The wooden flooring material of the present invention is made by coating the surface of a wooden substrate l with a paint containing powdered A4 fat wax to provide a coating layer 2, and with this structure, the above object is achieved. . The powdered resin wax contained in the coating layer 2 improves abrasion resistance, and since the powdered resin wax has a low specific gravity, it does not precipitate during the coating process, improving workability and improving the wooden substrate 1. The coating can be applied uniformly and there is no variation in quality. The present invention will be described below based on embodiments shown in the accompanying drawings. As the wooden substrate 1 used in the present invention, veneer plywood, hardboard, particle board, etc. are used, but the present invention is not limited to these. As the paint that forms the coating layer 2, Ami-7 alkyd resin liquid, polyurethane resin liquid, polyester resin liquid, acrylic resin liquid, vinyl chloride resin liquid, etc. are used, but the resin itself of polyurethane resin liquid is wear-resistant. It is preferable because it has excellent properties. This paint contains powdered resin wax. Examples of this powdered resin wax include polyethylene wax. This powdered resin wax is
Preferably, it is blended in an amount of 10 to 30% by weight based on the solid content of the paint. The paint containing this powdered resin wax is applied to the wooden substrate by brush, roll coater, 70-coater, spray, etc.
applied to the surface of In the embodiment shown in FIG.
A veneer 4 is pasted on the surface of the wooden substrate 1 to form a wooden base @1, and the veneer 4 of the wooden substrate 1 is sanded, colored after actual processing, and then powdered resin wax is mixed. The paint is applied at a coating amount of, for example, 3 to 5 g/shaku2, and then the surface of the formed paint film layer 2 is lightly sanded, and a top coat of paint that does not contain powdered resin wax is applied thereon. The surface coating layer 5 is formed, and the wooden flooring material A is manufactured. According to the Tea Bar abrasion tester, the surface of this wooden flooring material A recorded an abrasion rotation speed of 3000 to 4000, and can be used as a flooring material for people with shoes on. It is in no way inferior to wooden flooring materials that use solid wood. In the embodiment shown in FIG. 2, a cushioning material 6 is pasted on the back side of the plywood 3, a sound insulation sheet 7 is pasted on the front surface, and a veneer 4 is pasted on the sound insulation sheet 7 to form the wooden substrate 1. A coating layer 2 and a surface coating layer 5 are formed on the surface of the veneer 4 to constitute a wooden floor material A having excellent wear resistance, sound insulation, and vibration damping properties.

【Effect of the invention】

In the present invention, since a coating layer containing powdered resin wax is applied to the surface of the wooden substrate, the abrasion resistance is improved by the powdered resin wax contained in the coating film and layer. Moreover, this powdered resin wax has a low specific gravity, so it does not settle into the paint during the painting process.
It has good dispersibility, so the workability of painting is improved compared to the old days, and the coating on wooden substrates can be uniform, with no variation in quality.
