BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanging adhesive sheet for snow removal / heat collection or heating / cooling having a flow down regulation function, and in particular, it is attached to the surface of a magnetic material to form a flow path restraining path for a heat medium. The present invention relates to a heat exchanging adhesive sheet, specifically, a heat exchanging adhesive sheet which is used by being attached to a roof or wall surface made of an iron plate, a heat exchange metal board or a surface of a metal backup resin film structure.
When using this heat exchange adhesive sheet for iron plate roofs, running hot water along the heat exchange adhesive sheet can remove snow or melt snow on the roof in winter, and can collect solar heat in summer. Also, you can cool the roof and walls by running cold water.

2. Description of the Related Art Flow-down regulation sheets having a flow-integrated parallel structure for regulating the flow of liquid by alternately providing lyophobic parts and lyophilic parts on the surface of the sheet in a streak pattern are well known. The applicant has a history of subdividing such a flow regulation sheet into strips, examining a simple adhesive tape that can be easily attached to a desired surface to be adhered and used, and making various prototypes and evaluating them. Some of the initial prototypes have a structure in which a laminated tape made of a water-absorbent material / adhesive / polyester base material is attached to a surface to be adhered via a pressure-sensitive adhesive layer.

The problem of such an adhesive tape has been how to manufacture a reliable product having excellent durability including use under severe conditions and cases where special use conditions are required. . For example, in the case of tapes that are used in severe environments where wetting and drying are frequently repeated, direct exposure to sunlight, and high temperatures, swelling / drying / shrinking of the fibers that make up the water absorption regulation path causes adhesive There is a tendency for shear peeling with the fiber surface to occur relatively easily. Furthermore, buoyancy acts on the fiber structure that constitutes the downflow path in the downflowing heat medium. It was found that the fiber was broken due to the deterioration of the water-absorbent fiber, and the water-absorbent material was easily peeled off from the substrate after a short period of use. As a method of coping with such a problem, the applicant has evaluated and examined various fiber materials, and as a result, has found that a polyester yarn having poor water absorption but excellent weather resistance / mechanical strength and low expansion / shrinkage, and a spiral around the yarn. It has been confirmed that good results can be obtained by using a woven fabric, a non-woven fabric, or a knitted fabric composed of a composite yarn composed of vinylon fibers having excellent water absorbability wrapped around. In this way, by replacing the pulp fiber, rayon fiber, and cotton fiber, which have been experimentally studied in the past, with the fiber having the above-described structure, a strong flow-down that has been outstanding for a long time and has excellent weather resistance and is difficult to cut and peel off. It has become possible to manufacture trainer tape.

[0004]

Although a tape that can be marketed has been completed through such a development process, new anxiety materials have been found from recent experimental results. For example, when this tape is attached to a roof of a tiled iron plate, it has been observed that if the roof is repair-painted, the tape easily comes off due to peeling of the paint. When the tape is peeled off, the momentum of the flowing water causes the tape to move laterally, the intervals between the tapes are disturbed, uniform heat exchange cannot be performed, and a local short circuit occurs to lose the regulation effect. At the experimental stage, the adhesion between the base material and the surface to be adhered was good, but many of the actual painted surfaces of existing roofs have seen considerable deterioration, so strict tape installation work is required on site. Quality control is required. Further, since the iron plate is exposed to an environment that is more likely to be corroded by the flowing water, the adhered surface of the roof or the like to which the flow regulating tape is adhered has to be subjected to stricter paint management than the roof which is not so.

A detailed examination of the roofs of houses in the heavy snowfall region shows that scratches on the painted surface, which are thought to be caused by sliding snow, are noticeable, and that local corrosion progresses and red rust occurs in places. . The flow regulation tape interferes with the painting work for proper coating control, and the side edges of the tape where the running water or rainwater easily enters and the residual voids on the back side of the tape
It was found that the peeled surface remains unpainted and these parts may corrode before others and cause water leakage. As a countermeasure against this, a method of using a thick polyester film as a base material and making it possible to peel off the tape as much as possible without leaving the adhesive on the surface to be adhered is cooperated with the adhesive manufacturer and the adhesive tape manufacturer. I have made a prototype and examined it. However, satisfactory results have not yet been obtained. Without ensuring that the tape is fixed / removed / re-adhered, it is virtually unusable, for example, as a snow removal product for roofs on existing roofs except new roofs or well-managed roofs. Depending on the method of construction, if used for a relatively short period of time (for example, for a short period of time beyond one winter), the side edges of the flow control tape and the roofing on the back side will rapidly corrode over a wide area. There is a strong risk of frequent leaks. If the base material is thickened or a large amount of adhesive is used, these intervening layers become a heat resistance layer between the adherend surface,
It is difficult to use because heat exchange via the base material cannot be performed smoothly. If it is an upward surface such as a roof, the tape is left unbonded along the roof ground, and we are also studying a method to fix this tape with appropriate metal fittings. At present, it is difficult to prevent lateral movement.

An object of the present invention is to attach and detach a general-purpose device which can be easily attached to an adhered surface of any surface coating state, whether new or existing, can be used as it is, and can be removed when necessary. It is to provide an inexpensive heat exchange adhesive sheet having excellent properties. (The term "sheet" used here is a concept that includes a continuous body made of long strips or tapes, or a rectangular plate-like simple substance that is continuously arranged in large numbers.) This sheet is used for an iron roof In this case, it can be used as a snow removing sheet in winter and as a heat collecting or roof cooling sheet in summer.

[0007]

In order to achieve the above-mentioned object, the heat exchange adhesive sheet according to the present invention is made so as to stick to the adherend surface made of a magnetic material having a high magnetic permeability by the action of magnetic force. ing. At least a part of the sheet main body has, for example, a base material layer having a predetermined width and made of a liquid-phobic material composed of a ferrite magnet made of plastic or rubber having excellent thermal conductivity containing a large amount of iron powder, and a base material. The heat medium transfer path layer having a high liquid absorbing property is adhered to the front surface of the material layer.

[0008]

With the above-described structure, the adhered surface made of a magnetic material having a large magnetic permeability and the base material layer are in surface contact with each other, and the base material layer is adhered to the adhered surface and the heat medium movement path layer is It is fixed to the surface to be adhered. As the magnet, for example, a ferrite magnet containing a large amount of iron powder can be used,
This type of magnet has good thermal conductivity, and the base layer of the magnet functions as a heat transfer surface. Also, since the base layer of the magnet has a large specific gravity, it acts as a weight on the heat medium movement path layer, and the rubber itself has a large friction coefficient and is essentially a material that does not slip easily against the surface to be adhered, so it sticks to a flat surface. Together with the magnetic force, the heat medium movement path layer can be strongly bonded and fixed.

[0009]

EXAMPLE FIG. 1 is a perspective explanatory view showing an example of use of the heat exchange adhesive sheet according to the present invention in a roof tile roof. The illustrated heat exchange adhesive sheet (hereinafter, simply referred to as a sheet) has magnetic force by itself. The tiled roof constitutes the adhered surface 3 of a magnetic material having a high magnetic permeability, for example, an iron plate, and the sheet is used by being attached to the adhered surface 3 of the roof by a magnetic force.

The sheet comprises a base material layer 1 and a heat medium movement path layer 2 provided in contact with the base material layer. Base material layer 1
Can be made of, for example, a ferrite magnet made of plastic or rubber that contains a large amount of iron powder and has excellent thermal conductivity, and the entire substrate can be made of a lyophobic material. The heat medium movement path layer 2 is made of a material having a high liquid absorption property, and is bonded to the surface of the base material layer 1 on one side. The base material layer 1 can be manufactured by an extrusion molding method. The base material layer 1 and the heat medium transfer path layer 2 are integrated in such a manner that a part of the base material closes the joints of the heat transfer path layer to the extent that liquid absorption of the heat transfer path layer is not impaired. Has been done. Apart from this, as shown in FIG.
It is also possible to form the base material layer 1 by previously coating the heat medium moving path layer 2 with the primer layer 4 that closes the joint and adhering the coating primer layer 4 and the ferrite rubber magnet sheet 5 to each other. The rubber magnet sheet is, for example, 0.3
It can be used for items from mm or less to several tens of mm thick,
In the case of ordinary iron plate roofs and siding iron plate walls, those of about 0.2 mm to about 5 mm are used.

FIG. 2 shows a state in which the side edges of the base material layer 1 and the heat medium movement path layer 2 overlap each other and a step 6 having a height corresponding to at least the thickness of the two is formed on the adherend surface 3. FIG. According to this configuration, the heat medium flowing down can be converged by the liquid absorbing property of the heat medium movement path layer 2 and the adhesive force of the downflowing heat medium to the step surface, and the downflow direction can be restricted. In the figure, reference numerals 7 and 8 respectively indicate the flow of the heat medium flowing over the surface of the heat medium moving path layer and the flow of the heat medium adhering to the side edge portion of the sheet. 3 to 6 are perspective explanatory views showing a second embodiment of the heat exchange adhesive sheet according to the present invention. In each of the illustrated series of sheets, the width of the heat medium movement path layer 2 is set narrower than the width of the base material layer 1,
Due to the lyophobic property of the base material layer, a boundary region where the liquid absorbency changes is formed at the side edge of the heat medium movement path layer. A configuration is adopted in which the heat medium flowing down is isolated so as not to come into contact with the side edge portion of the base material, which is different from those in FIGS. 1 and 2.

FIG. 4 shows a comparative example, which is arranged at a distance from the side edge of the heat medium transfer path layer 2 and is disposed between the heat medium transfer path layer and the side edge of the base material layer 1. An example of a heat exchange adhesive tape having a narrow lyophilic or lyophobic boundary constraint path 9 is shown. If the boundary constraint path 9 is provided, the effect of blocking the movement of the heat medium in the lateral direction is further enhanced. The boundary restraint path 9 can be arranged on one side or both sides of the heat medium movement path layer.

The base material layer 1 of FIGS. 3 and 4 is composed of an upper layer 4a of a hydrophobic material and a lower layer 5a of a ferrite rubber magnet sheet, respectively. Base material layer 1 shown in FIG.
Comprises a hydrophobic material layer 4b and ferrite rubber magnet strips 5b arranged on both sides of the base material layer. The base material layer 1 shown in FIG. 6 is composed of a hydrophobic material layer 4b and a ferrite rubber magnet strip 5b arranged at a side edge portion of the base material layer and an intermediate portion of the heat medium movement path layer 2.

When the sheet shown in FIG. 5 is used, both sides of the base material layer 1 adhered and fixed to an arbitrary supporting surface are lifted up as compared with the middle portion of the base material layer, and the base material layer 1 is slightly bottomed. A curved depression is formed. The liquid flowing down is simultaneously subjected to the water-repellent action of the base material layer and the restraining action due to the depression.

When the sheet shown in FIG. 6 is used, the base material layer 1 adhered and fixed to an arbitrary supporting surface is raised on both sides of the heat medium movement path layer 2, and a slightly curved bottom is formed in the middle portion. Further, both sides of the base material layer form slopes with a downward slope.

The sheet having the structure shown in FIGS. 5 and 6 has a structure suitable for causing the heat medium to overflow from the heat medium moving path layer. These sheets, for example, when used as a snow melting sheet that pushes laterally the sherbet-like snow that has absorbed the heat medium or the sherbet-like snow that has floated in the flow of the heat medium, and slides off along the side edges of the base material layer. It is convenient. Using any of the tapes shown in FIGS. 1 to 6,
Even if the adherend surface is a three-dimensional surface having a complicated shape, it is possible to mount the regulation heat medium movement path layer at an ideal interval / direction by a simple and quick operation that does not require skill.

FIG. 7 shows a heat exchange adhesive sheet composed of a base material layer 1 of an extruded rubber magnet 5c having a modified cross section having a plurality of grooves 10 arranged in parallel, and a heat medium transfer path layer 2 arranged in the grooves 10. An example is shown. This sheet can be used for forming a snow melting walkway by being attached to the surface of the base iron plate frame 11 as well as being attached to a roof or a wall surface. The base iron plate frame has a form in which a plurality of members are connected and extended by using a connecting means, but a single continuous sheet can be used, and troublesome work such as connecting the heat medium movement path layer in the middle is required. It is unnecessary. The upper surface of the base iron plate frame 1 is arranged horizontally or with a certain gradient, and the supplied heat medium moves along the heat medium movement path layer. The base iron plate frame 11 is provided with, for example, an outer shell structure having level adjusting means, a peripheral heat insulating layer 12 and auxiliary heating means 13. A hot water pipe or an electric wire heater can be used for the auxiliary heating means 13.

8 to 11 are perspective explanatory views showing a third embodiment of the heat exchange adhesive sheet according to the present invention. Unlike those shown in FIGS. 1 to 7, these sheets are shown in a posture in which the base material layer 1 is located above. In addition, both the sheets shown in FIGS. 1 to 11 and the sheets described below,
The bonding posture and direction can be freely selected.

The sheet shown in FIG. 8 has a base material layer 1 made of a flexible magnet material, a heat medium transfer path layer 2 having a high liquid absorbing property, which is adhered to the base material layer, and a hydrophobic layer covering the layer. And a cover layer 14 made of a conductive material. In the example shown in FIG. 8, both sides of the heat medium moving path layer are exposed.

FIG. 9 shows a sheet in which one side portions of the base layer 1 and the cover layer 14 are adhered to each other, and one side portion of the heat medium movement path layer is concealed.

In FIG. 10, the base material layer 1 and the cover layer 14 are made of magnetic rubber or magnetic plastic which are continuous with each other.
The portion of the base material layer 1 is magnetized.

FIG. 11 shows a sheet with a cover layer 14 whose cross section has a curved cross section with a depression facing the side of the substrate layer. On the exposed surface of the cover layer, the second heat medium movement path layer 15 having a narrower width than the cover layer and rich in liquid absorption can be adhered.

FIG. 12 shows a modification of the sheet shown in FIG. 10 in which the width of the base material layer is wider than that of the heat medium moving path layer and the cover layer. This seat has the features of the seat shown in FIGS. 3 to 6 and the features of the seat shown in FIGS. 8 to 11.

FIG. 13 shows an example in which the sheet shown in FIG. 3 is modified so that the width of the base material layer is wider than that of the heat medium moving path layer and the cover layer as in the case of FIG. This sheet has the features of the sheet shown in FIGS. 3 to 6 and FIGS.
It also has the features of the seat shown in 1.

FIG. 14 shows a modified example of the sheet shown in FIG. 12, in which the width of the base material layer is wider than that of the heat medium movement path layer and the cover layer. This seat has the features of the seat shown in FIGS. 3 to 6 and the features of the seat shown in FIGS. 8 to 11.

In the above-mentioned sheet, the base material layer or the cover layer, or the heat medium transfer path layer adhered to the exposed surface of the cover layer can be colored in any color. These layer materials can be mixed with a dye that changes its color to any color depending on the temperature, or various energy conversion elements can be attached to the surface of the layer material. Colors such as black, red, and blue are convenient colors for collecting / dissipating heat.

With the above configuration, the fluid moving along the heat medium moving path layer moves in the path in which most of the fluid is hidden, and the exposed portion is limited to the portion along the side edge. . According to this structure, when the air in the heat medium transfer path layer is compressed, the air is exhausted from the release edge side of the heat medium transfer path layer, and when the flow rate is too high or excessive pressure is applied, the fluid is discharged from the release edge. It will flow out and will flow down along this outflow edge. Further, since the heat medium moving path layer is not exposed, the evaporation amount of the heat medium can be reduced. When the sheet is used by being attached to the attic of the factory building / barn, it is possible to prevent the heat medium from peeling off and dropping from the heat medium moving path layer.

When the flow rate is too high or excessive pressure is applied, the heat medium flows out from the open edge, but the exposed side edge of the heat medium movement path layer is spaced inward from the side edge of the base material layer. Therefore, the heat medium that has flowed out tends to flow down in a converged state along the outflow edge and does not come into contact with the side end surface of the base material layer. Therefore, it is possible to prevent the leakage heat medium from entering between the base material layer and the surface to be adhered.
