Abstract

PURPOSE:To enhance the heat conductivity while keeping cushioning property by including a metal material such as aluminium into a cushion body consisting of a foamed resin or fiber. CONSTITUTION:A metal body 1 consisting of aluminum powder is included into a cushion body (a) consisting of a foamed urethane resin. The including ratio of the aluminum powder is freely changeable depending on a required heat conductivity. The aluminum powder as the metal material is applied to the fiber 2 of coconut shell as occasion demands, and the fiber 2 is impregnated with a thermoplastic resin, heated and compressed to form the cushion body (a). Thus, the heat conductivity is kept by the aluminum powder applied to the fiber 2, the cushioning property can be held by the fiber 2, and since the cushion body can be thickened without limit, antimonic problems of cushioning property and heat conductivity can be simultaneously solved.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material having a high thermal conductivity which is optimal for laying on a floor heating system, for example.

[0002]

2. Description of the Related Art Conventionally known cushioning materials, particularly cushioning materials used for tatami floors, include, for example, foamed resins or fibers of palm husks.

[0003]

The conventional cushion material of this type must be thickened in order to improve its cushioning property. However, if it is thickened, the thermal conductivity will deteriorate. Therefore,
If the thickness of the cushion material is reduced in order to improve the thermal conductivity, the cushioning property will deteriorate. That is, the conventional cushion material has a trade-off property in terms of cushioning property and thermal conductivity. In the past, when this cushion material is used as a tatami mat, the cushioning property of the tatami mat is emphasized and the deterioration of the thermal conductivity is allowed to some extent. An object of the present invention is to provide a cushioning material having improved thermal conductivity while maintaining cushioning properties.

A first aspect of the present invention is a cushion main body made of foamed resin or fibrous material mixed with a metal material such as aluminum. The second invention is
The cushion body is constructed by impregnating the fibers of the outer skin of the palm with synthetic resin and compressing it. A third aspect of the invention is a cushion body mixed with aluminum powder. A fourth aspect of the present invention has a structure in which a large number of wires are mixed in the cushion body and the wires appear on both sides of the cushion body. A fifth aspect of the invention is one in which a cushion body is made of fibers sprayed with aluminum powder. A sixth aspect of the invention is a cushion main body made of foamed resin, fiber, or the like, in which a metal anchor is penetrated. A seventh aspect of the present invention is a cushion material in which at least one surface of a corrugated metal elastic body has a front member, and aluminum powder is applied to the surface of the elastic body.

[0005]

The cushioning material of the present invention as described above,
Since the metal with which the cushion body is mixed can maintain the thermal conductivity, the cushion body can be made as thick as desired. In other words, the thermal conductivity of the cushion body can be increased while the cushioning property of the cushion body is sufficiently maintained.

[0006]

EXAMPLE 1 In the first example shown in FIG. 1, a cushioning body a made of urethane foam resin was mixed with a metal material 1 made of aluminum powder. The mixing ratio of the aluminum powder may be freely changed according to the required thermal conductivity. When the conventional tatami floor is used as it is for floor heating, it takes about 2 hours or more for the surface temperature to reach 30 degrees.

In the second embodiment shown in FIG. 2, aluminum powder as a metal material is applied to the fibers 2 of the outer skin of the palm and the fibers 2 are impregnated with a thermoplastic resin and heated. The cushion body a is formed by compression. Therefore, the aluminum powder applied to the fiber 2 maintains the thermal conductivity and the fiber 2 maintains the cushioning property. In the third embodiment shown in FIG. 3, the fibers 2 of the outer skin of the palm are impregnated with a synthetic resin, and many fine wires 3 are mixed into the fibers 2 and compressed and fixed to the cushion. The material a is configured. However, the wires 3 are arranged such that they intersect randomly and at the same time, the wires 3 appear on the surface of the cushion body a. Therefore, the cushioning property is maintained by the fiber 2, and the thermal conductivity thereof is maintained by the wire 3.

In the fourth embodiment shown in FIG. 4, the cushion body a is constructed by impregnating the fibers 2 of the outer shell of the coconut with a thermoplastic synthetic resin and compressing it while heating it. Is. And this cushion body a
In addition, a large number of through holes 4 are formed, and a metal anchor 5 is passed through the through holes 4. Therefore, the metal anchor 5 can secure the thermal conductivity, and the palm fiber 2 can maintain the cushioning property. In the fifth embodiment shown in FIG. 5, the surface members 7 and 8 are provided on both sides of the wavy leaf spring 6, and aluminum powder is applied to the leaf spring 6. Therefore, the leaf spring 6 maintains the cushioning property, and the aluminum powder applied to the leaf spring 6 ensures the thermal conductivity.

[0009]

According to the cushion material of the present invention, since the metal material is mixed in the cushion body made of foamed resin or fiber, the thermal conductivity is maintained by the metal material, and the cushioning property is maintained by the foamed resin or fiber. Be drunk Therefore, the trade-off between cushioning property and thermal conductivity can be solved at the same time.
