Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to wood materials with anti-slip treatment used for flooring, etc., and the surface of the wood base material is blasted to create a wood grain-like uneven surface. By forming a rubber-like film on at least the concave portions of the uneven surface, the woody texture of the wooden base material is sufficiently produced, and a good anti-slip effect is maintained for a long time.

[Prior art and its problems]

Conventionally, wood materials with such anti-slip processing have been produced by layering resin-impregnated paper on the surface of the wood base material, overlaying a press circumference plate with an uneven surface on top, and applying heat pressure treatment to the resin-impregnated paper. There are products that have an uneven surface formed on the surface of the cured resin film. However, this type is designed to provide an anti-slip effect only with the uneven surface of the cured resin film, so it is weak against wear (and durable for long-term use). There is also the problem that the wood texture is lost because the wood grain pattern and the uneven pattern of the wood base material are not in sync.

In addition, there are also types in which the surface of a wooden base material is coated with a paint containing an anti-slip material such as silica sand, diamond sand, or alumina.

However, depending on the type of anti-slip material, the coating film becomes opaque or translucent, and the texture of the wooden base material is lost. There is also a product with a sheet pasted on it, but this has the disadvantage that the anti-slip sheet may peel off and the appearance is inferior8. By applying a plastic treatment to the base material surface to form a wood grain-like uneven surface, and forming a rubber-like film on at least the concave parts of this uneven surface, a good anti-slip effect is maintained for a long time, and the wood texture is also sufficient. I made it happen.

The flesh side shows an example of the manufacturing method for molding the anti-slip material of the present invention, and reference numeral 1 in FIG. 1 is a wooden base material. As this wood base material 1, for example, natural wood solid wood such as beech, maple, makamba, oak, zelkova, decorative plywood made by laminating veneers of these natural woods, etc. are used. Further, (2) the reference numeral 2 indicates the latewood portion of the wood base material 1, and the reference numeral 3 indicates the earlywood portion.

This wood base material 1 is subjected to a blasting treatment.

Blasting is performed using a normal blasting device that injects abrasive materials such as sand, silica sand, diamond sand, zircon sand, glass beads, steel grid, steel shot, stainless steel cut wire, and plastic grid together with pressurized air. be exposed. The pressure of pressurized air is 0.3
~0.7 MPa, and the particle size of the abrasive is 2
The range is from 0 to 240 meshes, and the projection density of the abrasive material is from 5 to 100 kq/positive2, which may be determined as appropriate depending on the species of the wood base material 1, the degree of grinding, etc. Note that since some abrasive materials remain on the surface of the blasted base material 1, it is desirable to remove them by blowing pressurized air after the blasting process.

Through such blasting treatment, the surface of the wooden base material 1 is
As shown in Fig. 2, the hard late wood part 2 of the wood base material 1 is hardly ground and remains almost intact, and the soft early wood part 3
is well ground to form recesses 4, and its surface becomes a woodgrain-like uneven surface 5 traced in a woodgrain pattern.

The uneven surface 5 of the blast-treated wood base material 1 can be subjected to a coloring treatment or a sealer treatment, if necessary. The coloring treatment is to color the uneven surface 5 of the base material 1 in a desired color tone, and a wiping coloring method is employed in which the colorant is immediately wiped off after being applied. As a coloring agent, a coloring agent such as a dye or a pigment is dissolved in a solvent and the concentration of the coloring agent is 0.
A coloring solution of 1 to 10% by weight is used, and if necessary, a resin such as an alkyd resin, a polyurethane resin, or an abanoalkyd resin is added to this solution up to 60i-3 yen, and/or calcium carbonate, diatomaceous earth, Fillers such as silica may be added up to 10% by weight to improve coloring workability, sealing effect, etc. The colorant is applied by brush, spray, or wiping coloring methods, and the amount of application is in the range of 5 to 1 (1!!/m2). Immediately after applying the colorant, use a cloth (rag). Wipe off the excess coloring agent using a cloth), sponge piece, etc. Through this coloring process, the earlywood part 3 of the substrate 1 is colored in a light color, and the latewood part 2
is colored in a dark color, further emphasizing the woody pattern.

In addition, during the next process of forming a rubbery film,
This is done by applying a sealer, which is used to prevent resin liquid from penetrating, and is commonly used for wood grain painting. Next, as shown in FIG. 3, on the uneven surface 5 of the base material 1,
A rubber-like film 6 is provided. The film 6 is formed by applying a liquid resin solution to the uneven surface 5 in many places. As the resin liquid, preferably a transparent or light-colored transparent liquid such as an uncrosslinked resin liquid of polyurethane elastomer or an organic solvent solution of acrylic elastomer is used, but polyurethane elastomer is most preferable in consideration of wear resistance. Although it depends on the degree of unevenness of the uneven surface 5, it is usually about 200 to 500 gZII&. Since a thick coating film is formed in this way, it is preferable to apply the resin liquid in two or more times. For the application, a brush coating, a reverse roll coater, etc. are used. If necessary, about 10 to 20 wt1 of a wear-resistant material such as α-alumina or aluminum hydroxide, which does not impair the transparency of the resin liquid, may be added to the resin liquid to further enhance the anti-slip effect. can.

Thus, with the configuration shown in Figure 3! It is also possible to use a wooden material with a non-slip finish, but if necessary, as shown in FIG. , the recess 4 of the earlywood part 3
. . . It is also possible to finish the state in which only the rubber-like film 6 is filled. In the case where such surface grinding has been performed, the filling state of the film 6 becomes even clearer.

[Effect]

In the case of a wooden material having such anti-slip force Roe /M, an uneven surface 5 in the form of a wood grain pattern remains, and a transparent rubber-like film 6 is provided on this uneven surface 5, so that the wooden base A non-slip effect can be obtained without impairing the wood feel of the material 1. In addition, the anti-slip effect is a combined effect of the uneven surface 5 of the base material 1 and the rubber-like film 6, Therefore, it is extremely excellent and lasts for a long time.Furthermore, since the rubbery film 6 is provided so as to fill the uneven surface 5, the rubbery film 6 will not peel off.

[Example 1] A bunamuku board material having a thickness of 20 liters was subjected to shot blasting under the following conditions to obtain an uneven surface with concave portions in the earlywood portion.

Abrasive material: 0.3 Ilul diameter, +Cf - Luyt' - Lu Projection speed: 50 winds/sec Projection density: 50~/2 Next, the uneven surface of this material was colored brown with wiping stain, and heated at 20°C. It was dried for 16 hours. next,
Apply a polyurethane elastomer-based transparent paint to this using a reverse roll coater.
After drying at 0℃ for 16 hours, the roughness of the coating film surface is divided by 240
I brushed it off with abrasive paper.

Furthermore, on top of this (:, apply the same transparent paint at 150.lit/% with a reverse roll coater,
After drying for 6 hours, a wooden material with the desired non-slip finish was obtained.

The entire wood material obtained is colored brown, and the recesses in the early wood part that has been treated with grains are filled with a rubber-like film made of urethane elastomer, giving it a beautiful appearance and a good anti-slip effect. Was.

[Effects of the Invention] As explained above, the wooden material of the present invention has a wood base material that has been subjected to a plasto treatment to have an uneven surface with a wood grain pattern, and a rubber-like film is formed on at least the concave portions of the uneven surface. Since it has been treated with an anti-slip finish, a high anti-slip effect can be obtained without damaging the wood texture of the wood base material, and this anti-slip effect can be maintained for a long period of time. Also,
It has the advantage that the rubber-like film adheres well to the wood base material and does not peel off.
