Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor material for heating, which is capable of chromatically capturing the temperature of the surface of the floor material by reversibly changing the color of the surface of the floor material.

[0002]

[Prior art]

 Conventionally, floor materials for heating have been widely used as one of the heating appliances, such as office floors in factories and floor materials for general households.In recent years, in particular, those having various functions and control surfaces have been widely used. Excellent ones have been developed in.

[0003]

[Problems to be solved by the present invention]

 However, with conventional heating floor materials, it is not possible to see the surface of the heating floor material from a distance and to check the on / off state of the switch and also the temperature state. They only touched the skin directly or visually checked the display scale from a short distance.

[0004]

[Means for Solving the Problems]

 The present invention has been studied in view of such a situation, and a thermosensitive color-developing film that reversibly changes color is attached to a hot water circulation pipe or a wood-based laminate containing a planar heating element. The above problems can be solved.

Hereinafter, an embodiment of the present invention will be described with reference to sectional views.

The wood-based laminate including the hot water circulation pipe (3) is a wood-based base material (1) made of a plywood, a particle board, a hardboard, or a composite material obtained by combining these. And a hot water circulation type heat generation panel in which heat-resistant plastic pipes such as polyester, polyethylene and polyamide are embedded in a soaking plate (2), and wood veneer thinly sliced from wood such as lauan, pine, oak and sen ( 6) is integrated by using an adhesive, or an adhesive and a fixing jig such as a screw or a nail.

Further, the wood-based laminate containing the sheet heating element (4) is a wood-based substrate (plywood, particle board, hardboard, and a composite material formed by combining these materials). 1), a sheet-like heating element (4) made by printing an ink containing a conductive material on a heat-resistant plastic film such as polyester or polyamide, and thin slices of wood such as lauan, pine, oak or sen The above wood veneer (6) is integrated by using an adhesive or an adhesive and a fixing jig such as a screw or a nail.

As the adhesive, a heat-resistant thermosetting resin-based adhesive such as a melamine-based adhesive, a urethane-based adhesive, or an epoxy-based adhesive can be used. In order to prevent the warp of the body, between the hot water circulation pipe (3) or the sheet heating element (4) and the wood veneer (6), as an intermediate material (5), plywood, particle board It may be possible to interpose a cord, a hardboard, or a composite material obtained by compounding these.

Examples of the thermosensitive color-developing film (7) that reversibly changes color include, for example, nematic liquid crystal polymer, cholesteric liquid crystal polymer, or mixed liquid crystal polymer obtained by mixing these liquid crystal polymers with gelatin, gum arabic, or the like. Microcapsules with an average particle size of several to several tens of μm depending on the wall film substance, and after adding a binder, the inked liquid crystal ink is reverse-coated on a plastic film such as polyester, polypropylene or polyamide. , A doctor blade coat, a gravure coat, and the like. The area of use of the thermosensitive color-developing film may be a part of the flooring material for heating or the whole area.

The thickness of the film is preferably 40 to 80 μm so as not to tear or wrinkle, and the coating amount of the liquid crystal ink is preferably 5 to 20 μm. If the coating amount is large, the cost will be high, and if the coating amount is small, the color developability will be low, and it will be difficult to identify the color that changes continuously.

Regarding the principle of color development, when heat energy generated from the hot water circulation pipe (3) or the planar heating element (4) is transmitted through the wood-based laminate and starts to reach the thermosensitive coloring film (7). The liquid crystal polymer or mixed liquid crystal polymer utilizes the property that the color perceived by the eyes changes because the arrangement state of molecules changes and the absorption of light changes. It is widely known as a phenomenon that occurs in. The color changes reversibly and continuously become red, orange, yellow, green, blue, and blue-purple in the temperature range of 20 to 50 ° C., but by appropriately blending the liquid crystal polymer described above. , It doesn't matter even if you change the temperature range of discoloration.

As a method for sticking the thermosensitive coloring film (7) to the wood-based laminate, at least one of the thermosensitive coloring film (7) and the wood-based laminate is coated with a viscous / adhesive agent, and then both A method such as crimping can be used. As the tackiness / adhesive, a wood-based laminate and a thermosensitive color developing film (7) can be sufficiently adhered. For example, an acrylic emulsion-based adhesive or a urethane-based adhesive can be mentioned. . The coating amount of the adhesive / adhesive is preferably in the range of 10 to 30 μm. If it is less than the lower limit, the adhesion between the thermosensitive color-developing film (7) and the wood-based laminate will be poor, and if it exceeds the upper limit, the cost will be high.

Furthermore, when the surface coating material (9) is applied to the surface of the heating flooring material of the present invention and dried, it has excellent wear resistance and is less likely to be scratched. As the surface coating material (9), a coating material made of a thermosetting resin such as a melamine resin, an unsaturated polyester resin, a urethane resin, or an epoxy resin can be used. The coating amount is preferably in the range of 40 to 60 μm. If it is less than the lower limit, the effect of abrasion resistance is small, and if it exceeds the upper limit, the cost is high.

Further, if the primer (8) is applied to the surface of the thermosensitive coloring film (7) before the surface coating material (9) is applied to the surface of the heating flooring material, the surface coating material (9) is applied. And the adhesion to the thermosensitive color forming film (7) are further improved. As the primer (8), a primer such as a urethane type primer, an epoxy type primer or a melamine type primer can be used. The amount of primer (8) applied is preferably in the range of 10 to 20 μm. If it is less than the lower limit, the adhesion does not improve, and if it exceeds the upper limit, the adhesion does not significantly improve and the cost increases.

[Effect of device]

 In addition to the impression of conventional wood, the flooring material for heating of the present invention can detect changes in temperature color by using a thermosensitive coloring film that changes color reversibly. You can check the off state and whether temperature control is appropriate.
