Abstract

PURPOSE:To achieve the bonding with good feeling efficiently as to time and cost, by heating and melting an adhesive sheet containing electrically conductive particles through dielectric heating to bond two plane base members, upper and lower ones, for use in a plane warmer. CONSTITUTION:A flexible heating wire 1a is disposed on a hot-melt adhesive sheet and heat fused to produce an dielectric heating adhesive sheet 1. This is sandwiched between a nap-raising right side cloth 3 as an upper plane base member and a heat insulating felt 2 as a lower plane base member and these are placed between the electrode plates 4 to be heated and bonded together by a high frequency power supply 5. Here the polymeric sheet containing electrically conductive particles shows the properties of Maxwell-Wagner type composite dielectric and produces a large amount of heat due to dielectric loss so that it can be used as an adhesive with large heating effect by dielectric heating. Thus, the bonding can be achieved very efficiently as to cost and time.

する。INDUSTRIAL APPLICATION FIELD The present invention relates to a method of adhering a planar heating device mainly used as an electric carpet. BACKGROUND OF THE INVENTION Conventionally, outer fabrics used for electric carpets and the like have been made of nonwoven fabrics such as needle punch felt, French pile, etc., and have relatively smooth surfaces and are hard with no cushioning properties. Smooth outer fabrics such as needle punch felt can be easily bonded by heat press using hot melt adhesive, whereas raised outer fabrics with good cushioning properties, such as general carpets, are bristled during the heat press process. There are various difficulties and restrictions in using raised fabric for electric carpets with built-in heaters, as the fabric may fall over. Specifically, the methods for adhering the raised outer fabric to the heater unit include: ■ A method of fusing a hot melt adhesive using a hot press. A method of adhering the hot melt adhesive at the same time as application. ■ A solvent-based or water-based emulsion adhesive. There are two methods: one method involves applying an adhesive and then bonding it over time, and the other method involves chemically crosslinking and curing the adhesive in a short period of time after applying the adhesive. Problems to be Solved by the Invention However, method (2) has a problem in that the raised pile falls down and the texture is impaired. In addition, in the case of a thick outer fabric, it takes a long time to heat the adhesive. Method (2) is difficult in terms of process and involves large process losses. In method (2), if a solvent-based adhesive is used, the solvent odor is severe, and if an aqueous emulsion-based adhesive is used, a long bonding time is required. Furthermore, the materials used in the @ method are limited, and there are very few materials that satisfy various performances. The bonding method for sheet heating equipment of the present invention solves the problem of poor efficiency and impairing the texture of the outer fabric, and achieves a bonding method that is efficient in terms of time and cost and has a good texture. The present invention provides a method. Means for Solving the Problems Solving the above problems, the method of adhering a planar heating device of the present invention uses an adhesive sheet containing conductive particles, heats it by dielectric heating, and attaches the upper and lower sheets of the planar heating device. It is used to bond two planar base materials. Function In the above method, the conductive particle-containing adhesive sheet is dried and solidified by the dielectric heating method, and the two planar substrates, the upper and lower sheets, are bonded together. EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. In the figure, 105Ω”C containing carbon black
71 ethylene divinyl acetate copolymer Hot-High Melt adhesive sheet (150 μm thick), 1 g of flexible linear heating wire (with a polyethylene adhesive layer as the outermost coating) is placed, heat-sealed, and heat-generating. It was set as wire base material 1. This is layered in a sandwich-like manner with a raised cloth 3 on the planar base material and a heat insulating felt 2 as the bottom of the planar base material, and placed between the electrode plates 4. to 1
A high frequency electric field of 2 MHz was applied for 40 seconds to heat and bond. Peeling adhesive strength immediately after adhesion is 4.3 KSI/2
．． It was 5 cm wide. Next, the content of the present invention will be explained in detail. Conductive particle-containing adhesive refers to an adhesive in which conductive particles or conductive whiskers are dispersed in a hot melt adhesive, with a volume resistivity of 102 to 108.
Ω・The best thing is what you eat. If this volume resistivity is too low, the heat generated will be too large, and if it is too high, the heat generation efficiency will be low and bonding will not be possible. Suitable conductive particles or conductive whiskers include those made of carbon black, copper, aluminum, tin oxide, and zinc oxide, of which carbon black and aluminum are most suitable. This adhesive sheet containing conductive particles exhibits properties as a Maxwell-Wagner type composite dielectric, exhibits a large dielectric constant and a large dielectric loss factor in a high frequency electric field, and generates a large amount of heat due to the dielectric loss. In this way, by using a hot melt adhesive as an adhesive containing conductive particles, it is possible to create an adhesive that has a large heat generation effect due to dielectric heating, and it is also most convenient to use it in the form of a sheet as in the present invention. Therefore, it is possible to provide a low-cost, high-efficiency bonding method. If this conductive particle-containing adhesive sheet has a large positive temperature coefficient of resistance (abbreviated as PTC), it will be quickly heated to the melting point.
After that, the temperature rise is small, so it can be heated more appropriately. This PTC material can be constructed by using a crystalline polymer as a Marx polymer. The dielectric heating method in the present invention is a method in which an adhesive having a high dielectric loss factor is heated under a high frequency electric field for bonding, and heat bonding can also be achieved by applying microwaves. As the high frequency electric field, one in the range of 2 MHz to several iQQMHz is used. Among them, about 6 to 3 Q MHz is practical. When applying this dielectric heating method, it is efficient that only the adhesive is heated most of the time, and other substrates are not heated directly. That is, it is important that the dielectric loss factor of the adhesive be orders of magnitude higher than that of other base materials. The conductive particle-containing adhesive sheet of the present invention satisfies this condition. Even when a flexible linear heating wire is included in the adhesive base material, if the heating conductor is a continuous wire without breakage, no local heating effect will occur in a high frequency electric field. Furthermore, even for electric wires coated with soft polyvinyl chloride having a relatively large dielectric constant (ε=5 to 10), the dielectric loss factor of the adhesive used in the present invention is orders of magnitude larger, so the present invention The adhesive method is very effective. Effects of the Invention The present invention enables bonding of planar heating devices using a very simple method, and provides a bonding method that is extremely efficient in terms of cost and time. Further, the conductive particle-containing adhesive sheet has good thermal conductivity and has the effect of spreading heat in the surface direction.

Detailed Description of the Invention The present invention relates to a dielectric heating adhesive sheet mainly used for electric carpets and a planar heating device using the same. BACKGROUND OF THE INVENTION Conventionally, the outer fabric used for electric carpets and the like has been made of nonwoven fabrics such as needle punch felt, French pile, etc., and has a relatively smooth surface and is hard and has no cushioning properties. Smooth outer fabrics such as needle punch felt can be easily bonded by heat press using hot melt adhesive, whereas raised outer fabrics with good damping properties, such as ordinary carpets, do not fluff during the heat press process. There are various difficulties and restrictions in using raised fabric for electric carpets with built-in heaters, as the fabric may fall over. Specifically, the methods for adhering the raised outer fabric to the heater unit are: ■Method of fusing hot melt adhesive by hot press ■Method of adhering real melt adhesive at the same time as application ■Method of using solvent-based or water-based emulsion adhesive There is a method of bonding over an hour after coating and bonding. There is a method of chemically crosslinking and curing the adhesive in a short period of time after applying the adhesive. Problems to be Solved by the Invention However, method (2) has a problem in that the raised pile falls down and the texture is impaired. Also for thick outer fabrics. It also takes a long time to heat the adhesive. Method (2) is difficult in terms of process and involves large process losses. In method (2), if a solvent is used, the solvent odor is severe, and if it is an aqueous emulsion, a long bonding time is required. Furthermore, the materials used in method (2) are limited, and there are very few materials that satisfy various performances. The bonding method for sheet heating equipment of the present invention solves the problem of poor efficiency and spoiling the texture of the outer fabric, and provides a bonding method that is efficient in terms of time and cost and has a good texture. This is what we provide. Means for Solving the Problems In order to solve the above problems, the dielectric adhesive sheet of the present invention and the planar heating device using the same use a dielectric heating adhesive sheet, the surface of which is heated and melted by dielectric heating, and the surface of the sheet is heated and melted. It is made by gluing together two planar substrates for a heating device. Function In the above structure, the dielectric heating adhesive sheet is heated and melted by the dielectric heating method, and the two planar base materials, the upper and lower sheets, are bonded together. Embodiment One embodiment of the present invention will be described below with reference to the drawings. In the figure, a flexible linear heating wire 1 & (a polyethylene adhesive layer is attached as the outermost coating) is placed on a 105 Ω ethylene-vinyl acetate copolymer hot melt adhesive sheet (150 μm thick) containing carbon black. ) was arranged and heat-sealed to obtain a dielectric heating adhesive sheet 1 in which heating wires were wired. This was layered in a sandwich-like manner with a raised outer cloth 3 on the planar base material and a heat insulating felt 2 as the bottom of the planar base material, placed between electrode plates 4, and powered by a high frequency power source 5. A high frequency electric field of 12 MH2 was applied between the picture electrode plates 4 for 40 seconds to bond them together by heating. Bealing adhesive strength immediately after adhesion is 4.
It was 3KP/2-5'm wide. Next, the content of the present invention will be explained in detail. The dielectric heat-adhesive sheet of the present invention comprises a dielectric heat-generating sheet at least whose surface is made of a hot melt adhesive, and the heat-generating sheet contains conductive particles formed by dispersing conductive particles or conductive whiskers in a polymer. Composed of polymer sheet. The structure of the dielectric heating adhesive sheet of the present invention includes that the entire sheet has hot melt adhesive properties,
There are two types in which hot melt adhesive is formed only on the surface of the heat generating sheet. The conductive particle-containing polymer sheet refers to one in which conductive particles or conductive whiskers are dispersed in a polymer, and a sheet having a volume resistivity of 102 to 108 Ω is most suitable. If this volume resistivity is too low, the heat generated will be too large, and if it is too high, the heat generation efficiency will be low and bonding will not be possible. Conductive particles and conductive whiskers include carbon plastic, copper. Suitable materials include aluminum, tin oxide, and zinc oxide, with carbon black and aluminum being the most suitable. This conductive particle-containing polymer sheet exhibits properties as a Maxwell-Wagner type composite dielectric, exhibiting a large dielectric constant (2000 to 300 Q or more) and a large dielectric loss factor in a high-frequency electric field, and generating large amounts of heat due to dielectric loss. do. In this way, by using the melt adhesive as an adhesive containing conductive particles, it is possible to obtain an adhesive with a large heat generation effect due to heat, and this can be further used in the form of a sheet as in the present invention. By doing so, it is possible to provide the most simple, low-cost, and highly efficient bonding method. If this conductive particle-containing polymer sheet has a large positive temperature coefficient of resistance (abbreviated as PTC). It is quickly heated to the melting point of the hot-melt adhesive on the surface, and since there is little temperature rise thereafter, it can be heated more appropriately. This PTC material can be constructed by using a crystalline polymer as a matrix polymer. The dielectric heating method in the present invention is a method in which an adhesive sheet with a high dielectric loss factor is heated and bonded under a high frequency electric field.
Heat bonding can be similarly achieved by applying microwaves. The high frequency electric field used is one in the range of 2M)lz to several 100MH7. Among them, about 6 to 80 M)lz is practical. When applying this dielectric heating method, only the adhesive is best heated, other substrates are not directly heated.
It is efficient that there is no heating. In other words, it is important that the dielectric loss factor of the adhesive be significantly larger than that of other base materials. The conductive particle-containing polymer sheet of the present invention satisfies this condition. Even when a flexible linear heating wire is included in the adhesive base material, if the heating conductor is a continuous wire without breakage, no local heating effect will occur in a high frequency electric field. In addition, even if the wire is made of soft polyvinyl chloride with a relatively large dielectric constant (ε=5 to 10), the dielectric loss factor of the adhesive sheet in the present invention is orders of magnitude larger.
The bonding method of the present invention is very effective. Effects of the Invention The present invention enables bonding of planar heating devices using a very simple method, and provides a bonding method that is extremely efficient in terms of cost and time. However, polymer sheets containing conductive particles have good thermal conductivity. It also has the effect of spreading heat in the plane direction.
