Abstract

PROBLEM TO BE SOLVED: To provide flooring excellent in moldability, lightweight, low in cost and high in dimensional accuracy by superposing an unvulcanized rubber sheet on a cork sheet, and pressurizing and heating both sheets by a molding press to integrate them in a layer state. SOLUTION: Cork grains crushed into proper grain size are mixed with an adhesive to compression-form a cork sheet 1 of desired thickness. An unvulcanized rubber sheet temporarily formed in sheet shape by mixing various rubber chemicals is superposed on the cork sheet 1 and pressed and heated by a molding press so as to be integrally formed in a layer state. A surface agent 3a can be disposed on a face, not superposed on the rubber sheet 1, of the cork sheet 1, and pressurized to form a coating face 3 for surface finishing. Flooring excellent in moldability, lightweight, low in cost and high in dimensional accuracy can therefore be obtained.

2. Description of the Related Art Conventionally, as a floor material mainly composed of cork material used for a house floor, a cork plate formed by forming cork grains into a sheet of a desired thickness is laminated on a core plate such as a plywood or a rubber plate. An integrated composite material is generally known. In recent years, instead of laminating the above-mentioned plate materials, as shown in JP-A-62-30859, cork particles having a desired particle size and vulcanized material are used. Adhesive is attached to the rubber particles obtained by grinding the finished rubber material to a particle size of a suitable size and mixed, and these are separated by vibration or powder dispersion to form layers having different specific gravities, and then formed into sheets. Floor materials that are integrally formed into a laminated structure have also been proposed.

However, in the case of the former composite material in which the cork plate formed into a sheet is bonded to a core plate such as a rubber plate, the surface of the cork material formed in advance is formed into a smooth shape, and this is used as a core. Since a complicated process such as bonding to a plate has to be performed, there is a great disadvantage that the cost is inevitably increased. Further, in the latter composite structure in which each of the vulcanized rubber material and the cork material is crushed to an appropriate size and molded integrally with an adhesive, it takes more time and effort than the above-mentioned bonded integrated structure, The molding process is also complicated and cannot be provided at a low cost.The finished product is formed by hardening the entire structure directly from the pulverized material. Many have left. The present invention eliminates such disadvantages, and provides a flooring material which is excellent in formability, lightweight, low-cost and has high dimensional accuracy. Hereinafter, this will be described in detail with reference to the drawings.

In the present invention, the cork material is pulverized to an appropriate particle size to form cork particles, an adhesive is mixed with the cork particles, and the mixture is compressed to form a cork sheet (1).
Next, a sheet-like unvulcanized dough rubber sheet (2a) is superimposed on the cork sheet (1), and this is heated and compressed to form a floor material comprising a cork sheet (1) and a molded rubber sheet (2). The cork sheet (1) has good sound insulation, compression recovery, decorativeness, and lightness due to the integration of dissimilar elastic plate materials without using an adhesive in this way. However, the rubber sheet (2) is combined with the high elasticity, extensibility or adhesiveness to obtain a floor material having a good walking feeling, high dimensional accuracy and durability.

Press 2 for about 8 to 20 minutes to cure and form. In the cork sheet (1) and the rubber sheet (2) formed as described above, the rubber material enters into a small gap between the cork particles of the cork sheet (1) and is hardened to form a tree root state. The cork sheet (1) firmly penetrates into the inside of the cork sheet (1), and shows entanglement and strong bonding. By utilizing the high permeability of the unvulcanized rubber material shown during compression in this way, physical bonding that is not fixed by adhesive force is realized.
