Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite material which is used in a part such as a floor material, a wall material or a ceiling material of a building where heat transfer performance is required in addition to soundproofing and vibrationproofing. Therefore, the present invention relates to a composite material having a thermally conductive fiber mat as one member, particularly a floor material composite material having the thermally conductive fiber mat as one member when a floor material is formed on a floor heating mat.

[0002]

2. Description of the Related Art For example, in a conventional floor heating structure, a floor material composed of an upper surface layer material, a base plate and a lower fiber mat is laid on a floor heating mat having an electric heating means and a hot water passing means. It is known to provide soundproofing in addition to the heating function.

The fiber mat is unavoidable for exhibiting soundproofing and vibration-proofing. However, on the other hand, since a large amount of air is contained therein and has heat insulating property, heat from the floor heating mat is transferred to the floor surface. The efficiency is extremely poor.

The present invention has been completed as a result of intensive studies in view of the above-mentioned problems of the prior art. A heat conductive fiber having improved thermal conductivity without impairing soundproofing and vibration damping of a fiber mat. A composite material including a mat as one member.

BEST MODE FOR CARRYING OUT THE INVENTION The heat conductive fiber mat according to the present invention is composed of an organic fiber, an inorganic fiber that also includes a metallic fiber, or a fiber non-woven mat made of a blend thereof, and preferably has a compression resistance and It is possible to employ a fiber including pressure resistant fibers rich in impact resilience and entangled fibers bridging between the pressure resistant fibers. The non-woven mat may be covered with a resin sheet or a cloth sheet for the purpose of preventing the shape loss and moisture absorption as necessary.

The ordinary fiber mat itself impedes heat transfer as described above, but the heat conductive fiber mat of the present invention is used in the fiber mat to improve the heat transfer. Fibers, such as metal fibers, ceramic fibers, etc., are used for some or all of the fiber materials,
Further, a heat conductive powder material or a far infrared ray emitting powder material, for example, a metal foil or a ceramic flake can be mixed. In the present invention, in order to exhibit heat transfer performance more effectively, a heat conductive sheet is attached to one side or both sides of the fiber mat.

The heat conductive fiber mat is provided as a lower layer, a surface layer material,
By arranging the plate materials made of a base plate in an upper layer and integrating them to form a floor material as a composite material, the floor material can be laid on a floor heating mat to complete a suitable floor heating system.

As the floor heating mat, a foamed resin mat or a fiber mat having a heating means such as an electric heating means and a hot water means incorporated therein is adopted. For example, a polyolefin having a foaming ratio of 30 to 50 times,
It is formed by using polystyrene or urethane resin and arranging a hot water pipe therethrough. Alternatively, a design such that a heat conductive metal sheet such as an aluminum foil is appropriately attached to the surface of the mat to make heat transfer good and uniform can be provided.

In the flooring material comprising the surface layer material, the base plate, and the heat conductive fiber mat, the surface layer material, for example, the veneer, has a thickness of 0.2.
It consists of thinly sliced wood of ~ 0.3 mm to less than 2 mm, and it is attached on a base plate which is usually made of plywood to give the floor surface a unique appearance of a wooden floor. However, the floor heating mat is arranged below, and in a severe environment such as a case where the floor heating mat is forcibly heated, the veneer is likely to be cracked or warped.
In order to suppress the above-mentioned problems, a plurality of thin wooden boards having a thickness of less than 2 mmm, which is the same as the veneer, are preferably formed by laminating three or more layers with their fiber orientation directions different from each other, and the upper layer above the upper layer. It is desirable to form a surface layer material having a thickness of about 2 to 3 mm by adhering and integrating veneer plates with different fiber orientation directions.

The base plate is usually made of three or more layers, for example, 5 to 7 layers of wood plywood. The thickness is not specified, but can be appropriately set within the range of 5 to 12 mm. As a means of imparting soundproofing / vibration resistance to the base plate, after attaching the base plate to the surface layer material, a large number are provided from the bottom surface side of the base plate upwards over a majority or full depth of the base plate. Engrave the slit. The slits can be arbitrarily formed such as those parallel to the width direction of the plate, or those parallel to the longitudinal direction of the plate, and the slit interval can be arbitrarily designed such as 10 mm to 100 mm.

In the present invention, the heat conductive fiber mat, which is placed below the base plate and is joined to and integrated with the base plate, is made of an organic and / or inorganic fiber as described above, and preferably in the fiber mat. The heat conductive fiber or far infrared radiant fiber, for example, metal fiber, ceramic fiber, etc. is adopted as a part or all of the fiber material, and the heat conductive powder or far infrared radiant powder material such as metal foil or Ceramic flakes and the like can be mixed. In order for the heat conductive fiber mat to exhibit heat transfer performance more effectively, it is essential to attach a heat conductive sheet, for example, an aluminum foil sheet, to one side or both sides of the fiber mat. The thickness of the heat conductive fiber mat is not limited, but is, for example, about 3 mm to 10 mm.

When the heat conductive fiber mat and the floor heating mat are in direct contact with each other, there are cases in which the floor sinks during walking or the like because of their flexibility, so that the fiber mat is in contact with the floor heating mat. An uprighting material may be appropriately interposed between the floor heating mat and the floor heating mat.

With the above-mentioned structure, not only the sound insulation performance can be maintained below the sound insulation class LL45 but also the transfer of heat to the floor surface when the floor heating mat is heated is remarkably promoted as compared with the conventional case. You can

The attachment means is not specified, but means such as stitching the aluminum foil sheet and the non-woven fabric mat with a needle punch or bonding the aluminum foil sheet and the non-woven fabric mat with a hot melt adhesive may be used. The floor material 6 is formed by composite-integrating the surface layer material 1, the base plate 2, and the heat conductive fiber mat 4.

Below the heat conductive fiber mat 4 to which the aluminum foil sheet 7 is attached, a sill member 8 made of, for example, plywood is provided as needed. As described above, when the floor heating mat 9 is arranged directly below the heat conductive fiber mat 4, there is a case where the floor sinks during walking etc. due to the increased cushioning property of both mats.
It is possible to suppress the adverse effect by interposing the attenuating material 8 between them, and when the abrading material 8 is peeled and removed to maintain and inspect the heating function of the floor heating mat 9, With the interposition, the floor heating mat 9 can be prevented from being damaged and peeled off easily.
