Abstract

PURPOSE:To prevent cracks generated on a thin veneer and increase the surface hardness of a floor wood. CONSTITUTION:A floor material is formed by bonding a thin veneer 4 on the surface of a base 1 by means of a soft bonding agent 3. Stress is absorbed by the soft bonding agent 3 provided with flexibility to prevent cracks to be generated on the veneer 4. Inorganic particles 32 as a filler are blended with the soft bonding agent 3. The hardness of the surface of the thin veneer 4 can be increased by the inorganic particles 2.

2. Description of the Related Art Flooring materials used to form indoor floors are those made by gluing veneers obtained by slicing logs onto the surface of a base material such as plywood. If a thin veneer with a thickness of 0.5 mm or less is used as the veneer, there is a risk that cracks will occur in the thin veneer when it is adhered to the surface of the base material. For this reason, by using a soft adhesive as the adhesive, the stress applied to the thin veneer is alleviated by the soft adhesive, and cracks are prevented from occurring in the thin veneer.

[Problems to be Solved by the Invention] However, when thin veneers are bonded using a soft adhesive in this way, the surface hardness of the flooring material decreases because the soft adhesive is flexible.
There were problems in that the feel of the flooring material deteriorated and it became easily scratched. The present invention has been made in view of the above points, and it is an object of the present invention to provide a flooring material that can prevent cracks from occurring in thin veneers and can increase surface hardness.

EXAMPLES The present invention will be explained in detail by way of examples. In the present invention, particles of silicon carbide (GC) or aluminum oxide (WA) can be used as the inorganic particles 2. These are particles with high hardness, and it is preferable to use particles with a particle size of 320 μm or less. Further, in the present invention, as the soft adhesive 3, an SBR adhesive or a water-based vinyl urethane adhesive can be used. These adhesives have more flexibility than phenol resins, epoxy resins, and the like. The inorganic particles 2 are mixed with the soft adhesive 3 in an amount of about 5 to 50% by weight (preferably about 30%).

[0007] When adhering the thin veneer 4 with a thickness of 0.5 mm or less obtained by slicing raw wood to the surface of the base material 1 made of plywood, particle board, etc., it is necessary to A soft adhesive 3 containing the above-mentioned inorganic particles 2 is applied to the surface, and a thin veneer 4 is placed on top of this. At this time, it is preferable to use the thin veneer 4 in a moist state to prevent cracking. By pressing this, a soft adhesive 3 containing inorganic particles 2 is applied to the surface of the base material 1.
A flooring material can be created by gluing thin veneers 4 together. When applying the soft adhesive 3, since the soft adhesive 3 has a high viscosity due to the inorganic particles 2, it is easy to apply the soft adhesive 3 with a uniform thickness. By blending the inorganic particles 2 into the agent 3, poor adhesion can be reduced. Since the soft adhesive 3 has flexibility, the stress applied to the thin veneer 4 can be alleviated by the soft adhesive 3 and cracks can be prevented from occurring in the thin veneer 2. Furthermore, since the soft adhesive 3 contains inorganic particles 2, the hardness of the surface of the thin veneer 4 can be increased by backing up the inorganic particles 2.

Effects of the Invention As described above, in the present invention, a thin veneer is bonded to the surface of a base material using a soft adhesive, so that stress can be absorbed by the flexible soft adhesive and the thin veneer It can prevent the occurrence of cracks, and since the soft adhesive contains inorganic particles as a filler, the inorganic particles can increase the hardness of the surface of the thin veneer. Therefore, even though a soft adhesive is used, a high surface hardness of the flooring material can be obtained.
