Detailed Description of the Invention

[0001]

The present invention relates to a building material,
The present invention relates to a building board in which the surface of a wooden board is covered with a resin film.

[0002]

2. Description of the Related Art Generally, wood boards such as plywood and particle board having a relatively smooth surface are used for construction, especially as a base material for construction. In recent years, in order to improve the water resistance of wood boards. A construction board whose surface is coated with a resin film such as polyolefin is used.

[0003]

However, the coefficient of friction of the resin film surface is generally small, and the surface of the building board coated with the resin film is slippery. In particular, water drops on the surface of the resin film are very slippery and dangerous. For example, at a construction site, a worker may be on the building board or work on it. Sliding his foot in such a case may cause an accident and impair the safety of the worker. It will be. In addition, when the building boards are loaded on a truck or the like, or when they are loaded on site, there is a risk that the loaded building boards may slip on each other and collapse.

Therefore, it is an object of the present invention to provide a construction board which has a non-slip surface and can enhance the safety of construction work.

DISCLOSURE OF THE INVENTION The present invention relates to a construction board in which the surface of a wooden board is coated with a resin film, and a solid powder such as a metal powder and a ceramic powder is attached to the surface of the resin film to form fine particles. The above object is achieved by providing a building board which is characterized in that it has irregularities. Further, in a building board in which a resin film is coated on the surface of a wooden board, the surface of the resin film is provided with a fine unevenness by sanding or sandblasting. By doing so, the above object is achieved. Furthermore, in a building board in which a resin film is coated on the surface of a wooden board, a large number of asphalt sheets coated with asphalt are bonded to the surface of the resin film. Thus, the above object is achieved.

[0006]

According to the present invention, since the unevenness is formed on the surface of the resin film in the building board to increase the slip resistance, it is possible to prevent the building board from slipping.

2A is a sectional view, FIG. 1B is a plan view, and FIG. 2 is a view of a building board according to a second embodiment of the present invention.
3A is a sectional view, FIG. 2B is a plan view, and FIG. 3 is a view of a construction board according to a third embodiment of the present invention.
3A is a cross-sectional view, FIG. 3B is a plan view, and FIG. 4 is a perspective view for explaining a test method for a slip resistance test.

First, the first embodiment will be described. As shown in FIG. 1, the building board 1 of the first embodiment is a building board in which the surface of a wooden board 2 is coated with a resin film 3, and the surface of the resin film 3 has metal powder and Solid powder 4 such as ceramic powder is attached to form fine irregularities. As the wooden board 2, ordinary wood, plywood, particle board or the like having a relatively smooth surface is used. The thickness of the wooden board 2 is not particularly limited, but is 9 to 3
0 mm is preferred. As the resin film 3, a resin film 3 which has been conventionally used for a building board is used.
It is a hot-melt resin such as an olefin resin, a fluorine-based resin (poly 4.3.2 fluorinated ethylene), a polyamide resin (nylon), polyvinyl alcohol, a polyvinyl chloride resin, and a cellulose resin. The thickness of the resin film 3 is preferably 0.01 to 2 mm, particularly preferably 0.03.
~ 0.5 mm. This is because if the thickness is less than 0.01 mm, the strength of the film is poor, and if it is greater than 2 mm, the film becomes unnecessarily thick.

As the solid powder 4, aluminum, iron,
Metal powder such as copper, ceramic powder, sand and the like can be used. The adhesion amount of the solid powder per unit area is preferably 0.01 g / cm ^{2 to 2} g / cm ² , particularly preferably 0.1.
It is from 03 g / cm ^{2 to 1} g / cm ² . The particle size of the solid powder is
Preferably 1-2 μm, particularly preferably 1-500 μm
Is. The solid powder and the resin fill may be fixed to each other by an adhesive agent or the like, but preferably by melt adhesion. That is, the heated solid powder is sprinkled on the resin film, the resin film is melted by heat, and the fixed powder is fused to the resin film. In the case of fusion bonding, the heating temperature of the solid powder varies depending on the type of resin film, but is preferably 80 to 500 ° C. This is because if the temperature is lower than 80 ° C, the resin film becomes difficult to melt, and if the temperature is higher than 500 ° C, the resin film melts too much and it takes time to fix the solid powder, and the resin film melts and flows.

Next, the second and third embodiments will be described. The same parts as those of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. Second
As shown in FIG. 2, the building board 11 of the embodiment is a building board in which the surface of the wooden board 2 is coated with the resin film 3, and the surface of the resin film 3 is finely ground by sanding and sandblasting. Unevenness 5 is formed. The irregularities 5 are randomly formed, but the average distance between the convexes is preferably 1 to 10 μm, particularly preferably 10 to 1 μm. The depth of the irregularities is 10 to 2 μm, particularly preferably 30 to 0.5 μm.

In the sanding method, the surface of the resin film is rubbed with sandpaper. The sandpaper used preferably has a coarseness of # 30 to #.
600, particularly preferably # 50 to # 120. The sand blast is a method in which sand particles are applied to the surface of the material at a high speed to form irregularities, and the sand particles to be used preferably have a particle diameter of 0.1 mm to 10 mm, particularly preferably a particle diameter of 0.
It is 5 mm to 3 mm. The blowing speed of such sand particles is preferably 1 m / sec to 100 m / sec, particularly preferably 10 m / sec.
m / sec to 50 m / sec. The amount sprayed is preferably 0.1 g / cm ^{2 to} 100 g / cm ² , particularly preferably 1 g.
/ Cm ^{2 to} 50 g / cm ² .

The construction board 21 of the third embodiment is shown in FIG.
As shown in FIG. 2, in the construction board in which the surface of the wooden board 2 is covered with the resin film 3, a large number of asphalt sheets 6 coated with asphalt are adhered to the surface of the resin film 3. .. As the asphalt, usual ones such as natural asphalt, coal tar and petroleum asphalt are used, but it is preferable to attach ceramic powder or sand particles to the asphalt. The asphalt sheet 6 should have a small thickness, but is preferably 0.1 mm to 1.0 mm. Asphalt sheet 6
Any size such as a square or a circle may be used, but a square shape having a side length of 10 mm to 300 mm is preferable, and the square asphalt sheets 6 are arranged at appropriate intervals. The total area of the asphalt sheet 6 is preferably 20 to 80%, particularly preferably 40 to 60% with respect to the entire surface area.
