Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber mat having excellent thermal conductivity and sound and vibration proof properties, and more particularly to a fiber heating mat on a floor heating mat. The present invention relates to a thermally conductive fiber mat which can be suitably used for attaching a wall / floor covering material or the like in which the present fiber mat is integrated to a heat source such as a mat or a sheet-like heat source, for example, by forming a floor flooring material in which the present invention is integrated. 2. Description of the Related Art For example, in a conventional floor heating structure, a floor flooring material in which a fiber mat is integrated is laid on a floor heating mat having heating means to provide a soundproof function in addition to a heating function. It is known to make it more comfortable to give. [0003] The fiber mat is inevitable in exhibiting soundproofing and vibration-proofing properties, but on the other hand, it impedes a large amount of air and has heat insulating properties, thereby impeding the efficiency of heat transfer to the floor surface. The present invention has been made in view of the above-mentioned problems of the prior art and has been completed as a result of intensive studies. The present heat conductive fiber mat has an effect of improving heat conductivity without impairing soundproofing and vibrationproofing. Is played. [0005] The present invention is a nonwoven fabric mat comprising organic and / or inorganic fibers, wherein a part or all of the organic and / or inorganic fibers are thermally conductive fibers and / or fibers. an infrared radiation fibers, the

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The heat conductive fiber mat according to the present invention is a part of a building or the like that requires soundproofing and vibration proofing, and is required to have good heat transfer during heating or the like. However, for example, it can be suitably adopted as one element of the soundproof floor heating structure. The heat conductive fiber mat is made of an organic fiber, a ceramic fiber, an inorganic fiber including a metal fiber, or a fiber non-woven mat made of a blend thereof, and preferably has compression resistance and rebound resilience. Fibers containing rich pressure-resistant fibers and entangled fibers bridging between the pressure-resistant fibers can be employed. The fibrous nonwoven fabric mat may be wrapped with a resin sheet or a cloth sheet as required for the purpose of preventing shape loss and moisture absorption. [0008] As described above, the ordinary fiber mat itself inhibits heat transfer. However, in order to improve the heat transfer, heat conductive fibers such as metal fibers, carbon fibers, and metal-coated organic and inorganic materials are contained in the fiber mat. Fibers, or far-infrared radiating fibers, for example, alumina fibers, zirconia fibers, ceramic fibers such as silica fibers can be partially or entirely employed, or further suitably heat conductive foil powder, far-infrared radiating foil powder, for example Metal foil powder, ceramic flakes and the like can be mixed. In the present invention, in order to exhibit heat transfer performance more effectively, it is essential to attach a heat conductive sheet, preferably a sheet made of metal foil, for example, an aluminum sheet, to one or both surfaces of the fiber mat. It is assumed that. A preferred example of the present invention is to provide a so-called soundproof floor heating structure by laying a flooring material on which a thermally conductive fiber mat is integrated on a floor heating mat having a heating means. In addition to the function, a soundproofing function can be provided to make the comfort more comfortable. In the soundproof floor heating structure, as the floor heating mat, a foamed resin mat, a fiber mat, or the like having a built-in heating means such as an electric heating means or a hot water passing means is employed. The flooring arranged on the floor heating mat, that is, the finishing material is composed of a surface material and a base plate, and the heat conductive fiber mat is integrated with this. As the surface material, a so-called veneer or a thin wooden plywood including the veneer is used, and as the base plate, a wooden plywood or a material obtained by engraving a suitable number of slits is used. In the present invention, the heat conductive fiber mat disposed below the base plate is made of organic and / or inorganic fibers as described above, and has a heat conductive sheet attached to the lower surface and / or upper surface thereof. Can be adopted, and the thickness of the mat is not limited.
It should be about 10mm. As described above, by adopting the heat conductive fiber mat of the present invention, the soundproofing performance can be maintained, and the transfer of heat to the floor surface when the floor heating mat or the like is heated is remarkably promoted as compared with the conventional case. can do.

Underneath, three layers of thin wooden boards are formed by laminating and adhering the fibers in different orientation directions. Reference numeral 2 denotes a base plate made of wood plywood, and in this embodiment, is formed by laminating and attaching five layers of veneers with different fiber orientation directions.

Although there is no particular limitation on the attaching means, for example, a means such as stitching the aluminum foil sheet and the nonwoven fabric mat using a needle punch, or bonding the aluminum foil sheet and the nonwoven fabric mat with a hot melt adhesive is used.
The floor finishing material 6 is formed by laminating and bonding the heat conductive fiber mat 4 to the surface material 1 and the base plate 2. Below the heat-conducting fiber mat 4 to which the heat-conducting sheet is attached, a piling material 8 made of, for example, plywood can be appropriately disposed. The presence of the waste material 8 facilitates peeling of the floor finishing material 6 in maintenance and inspection of the heat source mat, which will be described later, and also eliminates a drop in the floor and a feeling of instability when walking on the floor. . Further, the heat conductive fiber mat 4 or the waste material 8
