てしまうという問題があった。[Background Art] Conventional floor materials are, for example, simply a decorative board (projection board) stretched on a board made of plywood. Therefore, when the floor material is directly impacted, the floor material is transmitted through the floor material. There is a problem that vibration is transmitted to the base material, which is transmitted to the lower floor, which is not preferable for soundproofing. For example, in a condominium such as a condominium, there is a problem that vibration generated by a child traveling on the upper floor is transmitted to the lower floor and becomes noise.

た。Therefore, the present inventor has already attached a rubber sheet to the back surface of a wooden board in which a wooden decorative board, a soft sheet, and a substrate are laminated and integrated, and the floor material itself is provided with a soundproof and vibration-proof function. We are developing flooring materials. The rubber sheet used in this case is of the type that is usually used with a fibrous felt mat as a base material for carpets, and the construction method is mainly gripper construction, and the carpet is simply used without using an adhesive. Just lay it down. Therefore, this rubber sheet does not take adhesiveness into consideration, and in order to improve moldability, a lubricant such as oil and a release agent such as paraffin are blended in an amount of 11 to 17% by weight. Is oozing out on the surface of the rubber sheet, and therefore the adhesive strength to the concrete surface is weak, and it cannot be directly attached to the concrete surface, which is a restriction on construction.

It is characterized in that it is formed by molding a raw material containing 1 to 3% by weight, and the above object is achieved by this constitution. That is, the soft sheet 2 and further the rubber sheet 5 can ensure soundproofing and vibration damping. Further, since the rubber sheet 5 contains 2 to 15% by weight of a phthalic acid type plasticizer, the plasticizer is the rubber sheet 5.

A sheet-shaped material such as a synthetic resin foamed sheet is filled with metal, an inorganic material or the like to have a high specific gravity. For example, the soft sheet 2 is formed by mixing barium sulfate into a vinyl chloride resin sheet. Here, the high specific gravity soft sheet 2 usually refers to one having an area density (weight per m2) of 2.0 kg / m2 or more. When the surface density is high, deformation such as warpage is small and the corner floor material can be well set.

It is manufactured by masticating a raw material rubber, molding, including molding, molding, and vulcanization. In this case, rubber component 70 to 95% by weight, vulcanizing agent component 2 to 10% by weight, phthalic acid plasticizer 2 to
It is an essential constituent requirement that the raw material containing 15% by weight and 1 to 3% by weight of the release agent be molded and processed to be manufactured. The rubber component is a raw rubber or a synthetic rubber containing a filler such as a reinforcing agent, a bulking agent and an antiaging agent. As a vulcanizing agent component, a vulcanizing agent such as sulfur, sulfur chloride or benzoyl peroxide is mixed with a foaming agent such as sodium hydrogencarbonate or ammonium carbonate to make the rubber sheet 5 a foam, and thus the vulcanizing agent is contained. It is only necessary to increase the vibration damping property by the bubbles. As the phthalic acid-based plasticizer, general-purpose dioctyl phthalate, dibutyl phthalate and the like can be preferably used, and the range of 2 to 15% by weight is used as long as the adhesiveness can be improved without impairing the releasability. Is.
The release agent is preferably one that does not deteriorate the release property even if a large amount of plasticizer is used. As this type of mold release agent, for example, Separ, especially Separ # 365 (trade name, manufactured by Chukyo Yushi Co., Ltd.) can be preferably used. This Sepal #
365 is a compound in which a non-aqueous surfactant and a chemical structure having a releasing property are integrated, and examples thereof include a compound obtained by combining a non-aqueous surfactant with an alkyl phosphate ester.

In this embodiment, the front surface side is recessed to form a groove 12 corresponding to the convex portion 11 protruding downward on the back surface of the rubber sheet 5.
Corresponding to the recess 13 on the back surface, the front surface side protrudes to form a protruding portion 14. The Young's modulus of the rubber sheet 5 may be reduced in order to improve the vibration damping capability, but if this is done, the dent with respect to the load will increase. Therefore, by making the Young's modulus of the material itself relatively large, the depression with respect to the load is made as small as possible, and the rubber sheet 5 is provided with irregularities in order to reduce the apparent Young's modulus. For example, the Young's modulus can be reduced to 2/3 to 1/2 as compared with a flat sheet-like member by forming unevenness on the front and back surfaces of the rubber sheet 5 to form a corrugated shape. In addition, if the convex portion 11 protruding to the lower surface side of the rubber sheet 5 is made flat as shown in FIG. 11, the adhesiveness is improved when it is laid on a floor base material such as a building slab and bonded, for example. To do. Incidentally, FIG. 12 shows an embodiment in which the convex portion 11 and the concave portion 13 are provided only on the back surface of the rubber sheet 5.
木質床材Ａには長手方向の一側に嵌合突部15が突設して
あり、他側に嵌合凹部16が凹設してある。A fitting projection 15 is provided on one side of the wood floor material A in the longitudinal direction, and a fitting recess 16 is provided on the other side.

い。Then, the wooden floor material A is directly laid and laid on the concrete surface 7 such as the concrete slab of the building via the adhesive 6 as shown in FIG. Of course, the elastic base material may be laid on the floor base material and placed on the floor base material, or a joist or the like may be laid on the floor base material and laid on the floor base material.

%, Vulcanizing agent component 2 to 10% by weight, phthalic acid plasticizer 2 to 15% by weight, mold release agent 1 to 3% by weight. By matching it, the resonance of the wooden decorative board can be suppressed, the noise generated when a shock is applied to the floor surface can be reduced, and the lower rubber sheet can also be vibration-proof, and it is a rubber sheet to the floor base side like a building slab. Vibration is more difficult to transmit, and more reliable soundproofing and antivibration effects can be exhibited. Further, the rubber sheet contains 2 to 15% by weight of the plasticizer and 1 to 3% by weight of the release agent. Therefore, the plasticizer is uniformly dispersed in the rubber sheet without damaging the release agent,
The flexibility increases and it does not exude from the rubber sheet, the adhesiveness to the concrete surface is improved by the adhesive agent, it can be directly attached to the concrete surface, it is not only excellent in workability but also the walkability is improved, the wooden board The adhesiveness with and the interlaminar strength is increased, and peeling due to aging is eliminated.
