Abstract

PROBLEM TO BE SOLVED: To prevent a crack from arising on the surface of the floor material in which a rate of water content is generated partially by interposing non-woven fabric having as a main constituent element inorganic fiber, particularly, glass fiber between a wooden base material and a natural wood decorative veneer. SOLUTION: A floor material 1 is constituted of a main element of non-woven fabric 4 of main components of a wooden base material, a thin natural wooden decorative veneers 3 for decorative finish and glass fiber interposed therebetween. The floor material 1 is used as a laminate adhered itnegrally by a proper adhesive in a state where the non-woven fabric 4 is interposed between the thin natural wooden decorative veneer 3 and the wooden base material 2. In addition, glass fiber is 50% or more of the total fiber weight in the interposed glass fiber non-woven fabric 4, and the weight of the non- woven fabric is preferably 15-50 g/m2. Thereby the crack of the surface in a water-content rate difference caused by the time of a place exposed on strong direct sunlight, and use or the like of a hot carpet and partially occurring can be prevented comparatively inexpensively and easily.

2. Description of the Related Art Conventionally, wooden floor coverings finished with a thin veneer made of natural wood have been widely used mainly in houses, but in areas where sunlight is strong and illuminated for a long time, areas where hot carpets are laid. Alternatively, there is a problem that fine drying cracks are generated on the surface of the flooring material where a difference in moisture content occurs partially, such as a portion provided with floor heating, and this significantly impairs the commercial value of the flooring material.

Therefore, as a relatively inexpensive method for preventing cracking, paper or non-woven fabric mainly composed of natural fibers such as Japanese paper (pulp) or synthetic resin fibers such as polyester between a natural wood thin plate and a wood substrate is used. Has been implemented. However, in a living environment where the difference in moisture content is severe, such as underfloor heating, it is not enough to prevent drying cracks. In addition, instead of wood base material, MDF
There is also a method using a medium-density fiber board (MDF), but MDF absorbs moisture and the like once and does not return to its original state when it expands, so floor noise and thrusting between floor boards are permanent. There is a drawback that it may cause a problem.

The present inventor has focused on the fact that dry cracking occurs due to the difference between the dimensional change rate of the wooden base material and the dimensional change rate of the natural wood decorative veneer. The above problem can be solved by interposing a nonwoven fabric mainly composed of inorganic fibers, especially glass fibers, instead of the conventionally used Japanese paper or organic fibers, between the wooden base material and the decorative veneer of natural wood. And completed the present invention.

The thin natural wood decorative veneer 3 is preferably a thin one having a thickness of 0.5 mm or less, which is generally used, such as a rotary veneer of natural wood and a sliced veneer. For example,
A single plate such as oak, hippo, sen, etc. having a thickness of about 0.3 mm may be used. In addition, the natural wood decorative veneer may be resin-impregnated wood (WPC: Wood-Plastic-Composite) impregnated or coated with a polyurethane resin, an amino alkyd resin, a polyester resin or the like depending on the use. In the present invention, a suitable adhesive is applied with the glass fiber nonwoven fabric 4 interposed between the decorative wooden veneer 3 and the wooden base material 2, and integrated by a hot press or the like.

Here, as the glass fiber nonwoven fabric 4 to be interposed, the glass fiber is 50% or more of the total fiber amount, and
The nonwoven fabric preferably has a basis weight of 15 g / m 2 or more and 50 g / m 2 or less. In addition, glass fiber is fiberized by melt spinning with silica as a main component, E glass fiber,
It also includes silica fibers, ceramic fibers, and the like. Here, if the glass fiber content is 50% or less of the total amount of the fiber, the performance of the glass fiber stable against moisture and heat cannot be sufficiently brought out. The blending ratio of the glass fibers may be 100%, but pulp fibers, for example, may be blended to make the nonwoven fabric easy to handle. If the basis weight of the glass fiber non-woven fabric is 15 g / m 2 or less, it is difficult to manufacture the non-woven fabric, and it is difficult to obtain the effect of suppressing dry cracking. on the other hand,
If it is 50 g / m 2 or more, the adhesive for application easily penetrates into the nonwoven fabric, so that the laminating operation becomes complicated and the effect of preventing dry cracking is not necessarily increased.

One-half inch to about one inch is easy to manufacture as a nonwoven fabric and is the most suitable for the purpose of the present invention. Here, if the diameter of the glass fiber is too large, the effect of preventing cracking is low, and if it is too small, it becomes difficult to handle. Note that the glass fiber nonwoven fabric 4 may use a binder resin for bonding the fibers so that the fibers do not fall apart at the manufacturing stage, but the nonwoven fabric of the present invention is easy to handle if these binder resins are added as desired. It is. Generally, a thermoplastic resin-based adhesive such as an acrylic resin or a PVA resin is preferably used as the binder resin.

It is preferable to use an adhesive having at least one kind and desirably at least one kind of durability in order to prevent the floor material from cracking. When an adhesive having a performance lower than this is used, even if the nonwoven fabric is used, there is no durability such as water resistance, and it is difficult to obtain the effect of preventing cracking.

The anti-drying flooring material 1 according to the present invention comprises a nonwoven fabric 4 mainly composed of a specific glass fiber which is stable against moisture and heat interposed between a wooden base material 2 and a natural wood decorative veneer 3. In the state where it was made, epoxy used conventionally is appropriately applied to the floor base (inorganic materials such as concrete and mortar, wood materials such as plywood and particle board, and aluminum materials such as aluminum foil used for floor heating mat surfaces, etc.). A thermosetting resin adhesive such as a polyurethane-based or polyurethane-based resin is directly applied and used as an adhesive for construction. In this case, there is an effect of preventing the surface from being cracked, which is said to be caused because the dimensional change rate of the wooden base material and the natural wood decorative veneer differ due to the heat insulating effect of the nonwoven fabric.
