Description of the Related Art In a conventional electric carpet, as shown in FIG. 2, a heating wire 2 is arranged on a heat insulating material 1 and a surface material 3 on which a hot-melt adhesive has been applied and solidified is overlaid from above. The entire surface is heat-bonded by a heat press. As the surface material 3, specifically, a non-woven fabric such as needle punch felt or a surface material with short fluff such as French pile or tufted carpet with short fluff is used, and therefore, even if pressed by a hot press, the fluff Almost did not fall, and did not spoil the texture.

んど発生しない。According to this structure, since the PVC sol containing the foaming agent retains its fluidity at room temperature for a long time, it is possible to apply the surface material at another step, that is, at another place after applying it on almost the entire surface of the heat insulating material. As a result, the facility can be made equivalent to that of a conventional electric carpet manufacturing facility, the process is not difficult, and the process loss is small. Moreover, since the PVC sol containing the foaming agent has fluidity maintained by the plasticizer and does not use a volatile solvent, almost no odor is generated in the planar warming tool during or after the production.

The texture of is not damaged. Therefore, it is possible to obtain a surface warming tool which has a good texture of the surface material, high commercialability, efficient production, and low cost.

As shown in the figure, a heating wire 2 such as a tubing heater is laid on a heat insulating material 1 on a base material 4 to form a heater unit 5, on which a PVC sol 6 containing a foaming agent is applied at room temperature. . Then, after further superposing the surface material 3 on it, the whole is heated to cause the foaming agent-containing PVC sol 6 to undergo curing and foaming reaction. The optimum heating condition is heating at 120 ° C. to 160 ° C. for 2 minutes to 5 minutes, and heating with dry hot air is effective, but other heating methods may be used. A foaming ratio of 2 to 5 is suitable.

When the PVC sol 6 containing the foaming agent is applied from above the base material 4, the PVC sol 6 containing the foaming agent oozes out toward the heat insulating material 1 through the gap of the base material 4, so that the heat insulating material 1 and the surface material 3 are heated. It can be integrally bonded via the unit 5. Although the heater unit 5 in which the heating wire 2 is wired to the base material 4 is used this time, the heating wire 2 may be directly wired to the heat insulating material 1.

PVC sol 6 containing a foaming agent can be cured and foamed,
It can be manufactured with almost the same equipment as conventional electric carpet manufacturing equipment. Therefore, it can be efficiently produced at a cost substantially equal to that of the conventional electric carpet.
