However, the strength of wood veneers is directional, such that the tensile strength in the direction parallel to the wood grain <ff1m> is strong, but the tensile strength in the direction perpendicular to this is extremely weak.
In the case of a heated floor, there is a large temperature difference that acts on the veneer between when the heating is on and when the heating is not, and the veneer is subject to repeated expansion and contraction, which can cause cracks in the veneer in the direction of its weak strength. There was a problem that it was easy to occur. For this purpose, W.P.
C treatment has been applied to increase the strength of the veneer, but WPC treatment requires a large number of processing steps, and since WPC treatment is performed by injecting resin, it has a plastic-like appearance. This results in a loss of the feel of the wood material. The present invention has been made in view of the above points, and is based on the WPC
The object of the present invention is to provide a flooring material for a heating floor that reduces the occurrence of cracks in the board that is struck without the need for treatment. [1 [Means for Solving the Problem] The present invention provides a flooring material 2 for a heated floor provided with a heating element 1,
The veneer 3 to be attached to the surface of the flooring 2 is formed by pressure-molding a large number of thin wood pieces 4 together with an adhesive.

The present invention will be explained in detail below with reference to Examples. In the present invention, as the veneer 3, for example, the one disclosed in Japanese Patent Application No. 62-271076 provided by the present applicant can be used. That is, as shown in FIG. 4, an adhesive is first applied to a thin piece of wood 4 (for example, a Planar shaver product) obtained by slicing a piece of wood 6. The thickness of the wood slice 4 is 0.05~
0.80-1 (preferably 0.10-0.50-1) and area 6-400-12 (preferably 25-250-1)
2), and the aspect ratio (vertical width/i[) is 0°4 to 7.0 (preferably 0.8 to 3.0). It doesn't matter if it's curled, or if the above shape is 60% or more, it doesn't matter if dimensions other than the above are mixed in. By using emulsion adhesives, soft polyester resins, vinyl acetate adhesives, etc., the elongation rate is 30% or more.
The adhesive, which is preferably 500%, can be applied to the wood thin pieces 4 by spraying or cross-wire.First, the wood thin pieces 4, 4, . Compression molding can be carried out, for example, using a press device 10, and as shown in FIG. be able to. This press device 10
The pressing pressure may be sufficient to crush the wood flakes 4 along the pressing surface, and should be between 2 kg/c+s" and 50 kg/c+s".
Kg/cm2 (preferably 7 to H/cm”-1
4Kg/cm') is common. A veneer 3 can be obtained by slicing this 7-rich piece 9 with a slicing blade 11. Here, when the veneer 3 is created by assembling the wood thin pieces 4,
The wood thin pieces 4 are stacked parallel to each other along the press surface during compression molding, but each wood thin piece 4, 4.
The direction of the grain (texture) of ... is randomly oriented in all four directions (
Therefore, the direction of the wood grain (structure) in the veneer 3 is also random. Therefore, the veneer 3 created in this way
Because there is no directionality in the grain (structure), there is no directionality in strength. *If the wood flakes 4 are used like an octopus, the wood flakes 4 are easily deformed during compression molding, and bonding failure due to voids and foaming of the adhesive due to insufficient pressure will not occur.
In other words, if the wood pieces are obtained by crushing wood like particle board, voids may be created during press molding, or poor adhesion or foaming may occur due to insufficient pressure. are arranged in parallel, creating voids.Furthermore, the entire surface of the wood lamella 4 is approximately the surface, and the veneer 3 is formed by applying a large amount of adhesive.
This makes it possible to increase the amount of resin in the veneer, making it easier to bend the veneer 3, and reducing the occurrence of warping. Next, a specific example of manufacturing the veneer 3 will be explained. (14: Body side) Wood thin pieces 4 were obtained by finely slicing Japanese pine, with a thickness of 0.10 to 0.40 mm 11 area 12 to 200 m5",
Using a material whose main component (80% or more) has an aspect ratio of 1.0 to 3.0, apply urethane adhesive (GA601 manufactured by Juju Bakelite Co., Ltd.) to this 100 g of wood thin piece 4.
-Of) by adding 70g of adhesive and kneading the wood flake 4.
A 7-rich 9 is created by pressing at a pressure of Kg/cs2 for 1 hour, and this 79-rich 9 has a 0.50 to 0.60
A veneer 3 was obtained by slicing it into a thickness of about mm. FIG. 1 shows the veneer 3 obtained as described above on a substrate 14.
This shows a flooring material 2 formed by pasting it on the surface of
It is preferable to use water-resistant plywood, for example, plywood treated with WPC, as the substrate 14, and when forming the entire thickness to 15+ui, it is preferable to form the thickness of the veneer plate 3 to about 0.5 ring. The floor material 2 formed in this manner can be used, for example, as a heated floor shown in FIG. In the heated floor shown in Fig. 2, a hot water pipe 11 for circulating hot water is used as the heating element 1, and a heat equalizing plate 19 is hung between the joists 13 installed on the main drawer 12, and this heat equalizing plate At 19, the hot water pipe 11 is installed, and the joist 1 is installed so as to cover the top of the hot water pipe 11.
The flooring material 2 is placed between the 3 upper spaces. FIG. 3 shows another embodiment of the present invention, in which an electric heater 15 is built in the flooring material 2 as a heating element 1, and by attaching the flooring material 2 to the subfloor, a heated floor can be created. This is so that you can configure it. That is, an electric heater 15 and a heat equalizing plate 19 pasted on a protective sheet 18 are attached to a recess 17 on the upper surface of a base material 16 formed of plywood, and a surface material such as WPC plywood is pasted on top of the above-mentioned veneer 3. 20 is attached to the upper surface of the base material 16, the floor material 2 can be formed. In the heating floor formed as described above, hot water pipe 1
The veneer 3 of the flooring material 2 is repeatedly subjected to cold and heat effects by the heating element 1 such as 1 and the electric heater 15, but the veneer 3
Since there is no directionality of wood grain (structure) or directionality of strength, and since it is reinforced with the adhesive resin contained, it is possible to reduce the occurrence of cracks in the veneer 3. By the way, if you repeatedly test cold and heat on a sliced veneer of natural wood oak, it will be 10100mm x 150mm.
A crack of 1ms+ or more occurs with the test size of
In the veneer created as above (specific example), 1
No cracks occurred in the repeated cold/heat test, which repeated 20 cycles of heating at 00°C for 2 hours and cooling at -20°C for 2 hours.
In a water resistance test that repeated 10 cycles of drying for 2 hours at 60°C, no cracks occurred, and even at 80°C.
No cracks occurred in a heat resistance test in which the film was dried for 8 hours at room temperature and left at room temperature for 16 hours, repeated 10 times.

As described above, in the present invention, the veneer to be attached to the surface of the flooring material is formed by pressure-molding a large number of thin wood pieces together with an adhesive. The direction of the wood grain (structure) becomes random depending on the orientation of the many wood flakes, and the veneer loses its strength directionality.Moreover, the veneer is reinforced by the adhesive resin it contains. It is possible to reduce the occurrence of cracks in the veneer even if the veneer is subjected to repeated cold and heat effects by the heating element.
There is no need to perform C processing.
