Description

Planar heating element using a conductive sheet and a method of manufacturing the same {a plane heater by the use of conductive plastic sheet and a methode for manufacturing of plane heater}

The present invention relates to the field heating element.

First, the technical field of the planar heating element will be briefly described.

In the past, heating wires (aka nichrome heating wire, silicon heating wire) have been mainly adopted as heating means in electric blankets, heating mats, heating beds, thermal cushions, thermal vests, ondol panels, building floor heating, and anti-fog. In the case of linear heating, electromagnetic waves are generated a lot, and the phenomenon of avoiding hiring is particularly noticeable. Especially in Europe, where there are severe restrictions on the generation of electromagnetic waves, heating products of heating type are hardly found in the market. In addition, it is a heat generating means that is gradually disappearing due to the high burden of electric charges compared to the planar heating element.

Therefore, as a technology for replacing the heating means of the heating wire method, a new field of a planar heating element having a considerably low generation of electromagnetic waves and a high thermal conversion efficiency has been born, dating back several decades, A planar heating element that has been invented or improved in various ways has been commercially available or its technology has been disclosed.

In short, as an alternative to the conventional on-line heat generation, a planar heating element that generates heat evenly over the entire surface using carbon is mostly used to lead the heating market.

Among the known contents, to summarize the common technique of the method of manufacturing or constructing the planar heating element, the heating material mostly uses conductive carbon or mixed metal, and the conductive material is powder or paste material. Or it is provided as a mixed solid material, so that the heating means is provided by a method such as vapor deposition, printing, fibrosis, coating, painting, mixing crosslinking molding, etc. Has been provided.

In the above background, an embodiment of the prior art of the planar heating element which is being distributed in the domestic and overseas or the technology is disclosed will be described.

4 (A), (B), and (C) are as follows in plan view, partial enlarged view, and partial enlarged cross-sectional view of an embodiment of a planar heating element using conventional carbon fibers.

As the plane heating element is a medium product that began to form the market, in particular, has been produced mainly in Japan, as a fiber woven planar heating element 200, which is provided by weaving in a method of arranging carbon yarn in the middle with normal fibers ,

First, as shown in FIG. 4A, after weaving the fiber yarns 205 and the carbon fiber yarns 201 at predetermined intervals to form a sheet, the respective carbon fiber yarns 201 lines Both ends are sewn with a silver thread several times so that the circuits are configured in parallel so that the silver conducting electrode 210 of the power supply lines Ala and Alb is provided. The portion generates heat and the portion “B” does not generate heat, and is an example of a conventional carbon fiber type planar heating element which is called a planar heating element but is relatively incomplete.

4B is an enlarged view of the original designation of the symbol “A” of FIG. 4A, and the conductive electrode 210 is configured by sewing several strands, that is, repeated several times using a gift. It is shown.

4 (C) shows enlarged cross-sections of the sections “B” and “C” in FIG. 4 (A), and the portion woven from the general fiber yarn 205 and the carbon fiber yarn ( It is shown that the portion of the conductive conducting electrode 210 woven in 201) is sewn.

The planar heating element using the carbon fiber yarn is one of the methods of gradually decreasing demand due to the high manufacturing cost, and the disadvantage of being relatively expensive, and the disadvantage of having a special insulating coating due to its strong absorbency due to the characteristics of the fiber, When bending or folding, there is a problem of intensive heat generation in the deformed part, and that is, according to the crimped connection, that is, by forming a conductive electrode by sewing with silver, repeated sewing in several lines to prevent the increase in contact resistance of carbon and silver yarn, the strength of the sewing site is weak There is also a disadvantage.

5A, 5B, and 5C show a plan view and a partially enlarged cross-sectional view of an embodiment of a planar heating element using a conventional heating paint, as follows.

Since the planar heating element has been growing in the market since the beginning of the market, various methods have been changed, improved, and supplemented, and have been produced mainly in Korea, the UK, and Japan. (A product which is distributed in Korea, for example, there is a product called "NEOTEK") is formed on one side of the thermoplastic resin film fabric by forming a heat generating film layer by a method such as vapor deposition, printing, coating, painting, and the like. When heat is applied to the film, it generates heat. The planar heating elements 300a and 300b of the heat generating film forming method provided by constructing a conducting electrode by a method such as attaching a conductive copper tape, coating a copper foil, printing a conductive paint, etc.,

First, as shown in FIG. 5A, the thermoplastic resin film 305 is coated with a heat generating paint in a band shape in succession at predetermined intervals to form a heat generating portion (“H”) line (for reference, Examples of embodiments provided by companies such as Wuchang Far Infrared Heater and Tantan Co., Ltd., where information is known on the domestic Internet, and conductive paint printing or copper foil coating treatment so that both ends of each heating line 301a line are configured in parallel circuits. Thus, the conductive electrodes 310a of the power supply lines Cla and Clb are provided so that the portion “H” of the coating having the heat generating paint generates heat, and the portion “B” of the portion of the drawing “B” does not generate heat. As a planar heating element, a first embodiment of the planar heating element 300a of the conventional heating coating film treatment method, which is referred to as a planar heating element, is relatively incomplete.

As shown in FIG. 5B, the thermoplastic resin film 305 is treated with a coating film (a method such as deposition, coating, printing, painting, etc.) on the entire surface to form a heat generating portion (“H”), The copper plate coating or the conductive copper tape is bonded to both sides of the heat generating surface 301b so that the conducting electrode 310b of the power supply lines Tla and Tlb is provided, and the heat generating paint is coated. A portion "H" generates heat and shows a second embodiment of the planar heating element 300b of the conventional heating coating film treatment method as a relatively perfect planar heating element.

FIG. 5C is a cross-sectional view of the original circle "S" shown in FIGS. 5A and 5B. The heat generating layer portion 301 is coated on the resin material film 305. It is shown that the conductive electrode 310 is provided at predetermined intervals of the heat generating portion.

The planar heating elements 300a and 300b of the conventional exothermic coating film treatment method described above have a thickness of 50 μm to 200 μm by using a heat generating special paint on the thermoplastic resin film 305 having a thickness of about 0.1 mm to 0.4 mm (mm). Film (also referred to as coating) to form a planar heat generating portion 301 of the heat generating action means, and when the operating power source is 220 volts, at an interval of about 50 to 100 Cm (adjusting the calorific value depending on the interval). The conductive electrode is composed of conductive copper tape, copper foil coating, conductive paint printing, etc., and 100 to 400 watts per square meter (lower heat generation is used for heating plates, higher ones for heating of stone beds, etc.). It has the characteristic which shows a calorific value.

The disadvantages and problems of the planar heating elements 300a and 300b of the conventional heating coating film treatment method will be described below.

First, in the portion “S” of FIG. 5, that is, the portion where the heat generating film and the conducting electrode are bonded, a local spark problem is frequently caused by an electrical spark or an increase in contact resistance. Vibration, bending, folding, and pressing caused by the action of external physical forces are causing their quality problems more seriously, which is a technical problem that many companies do not produce plane heating elements due to such quality and reliability problems. It is a reality that is emerging as an eternal task for intensive study,

Second, uniformity management of the film thickness is required for uniform heating, which is an advantage of the planar heating element, and its yield is difficult to manage, resulting in a low yield of mass products, and if a dedicated production facility for uniformity is required, a huge investment must be made. This problem is a cost increase factor, and this problem is an eternal homework for many companies that produce planar heating elements, and is still being tried in various ways. Will be

Third, the exothermic layer coated with the exothermic paint is relatively low as 50 ~ 500 kPa, based on the "ASTM-D-257 Test (American Society for Testing and Materials)" method. Since the electrode becomes wider (electrode spacing of about 50 to 100 Cm when driven by an AC power source of 220 volts), a heat generating component (fermentation heater of kimchi refrigerator, damper heater of refrigerator, etc.) employed in electric and electronic products, Or there is a disadvantage in that it does not respond properly to the heating device installed in the narrow space of the building is inferior in terms of marketability,

Fourth, there is a disadvantage in that the rise in cost of goods and royalty expenses and mass productivity cannot be provided due to the scarcity of the heating paint provided as a heating means,

Fifth, dozens of types of exothermic paints have been developed and marketed, but the film of the exothermic layer provided by printing, painting, evaporation, etc., and after about 100 days has elapsed, the film is somewhat hard (hard). It is a reality that the film is easily cracked due to the repetitive or physical deformation of the contraction-expansion of the heating element, and most companies developing and developing a heating material are The reality is that it takes a lot of development costs to recognize the problem and to release the improved complement paint.

Another conventional embodiment will be described.

6 (A) and 6 (B) will be described below as a plan view and an enlarged cross-sectional view of an embodiment of a heating element using a conventional heating wire 400.

Ordinary heating wires (also called "heating wires") 401 which are generated by electricity to the insulating resin material film or the insulating fiber material or the thin film aluminum sheet 405 are arranged at predetermined intervals, and the electrical supply lines at both ends thereof. The heating element 400 of the heating wire system constituted by connecting 410, " Wla " and " Wlb " is shown in (A) in plan view and in enlarged cross-sectional view in (B).

The heating element 400 of the conventional heating wire method has the advantages of low manufacturing cost, long history and tradition, but there is a risk of fire due to local overheating when bent or folded in use, excessive radiation of electromagnetic waves and It has the disadvantage of low electrical heat conversion efficiency, and gradually decreases in use and demand, and is a technology used in the field of making cheap and easily discarded.

First, the contents of the conductive resin material sheet for providing a heat generating means in the planar heating element according to the present invention and the known contents of the conductive paste material for forming a conducting electrode for flowing electricity to the sheet will be described.

In the conductive resin material sheet, the conductive resin material compound, which is usually provided for manufacturing purposes such as antistatic articles and electromagnetic wave shielding articles, is a raw material for processing, and the conductive resin material compound is "PS" (polystyrene), " In thermoplastic resin materials such as PP "(polypropylene)," ABS "(ABS), and" HIPS "(high impact polystyrene), conductive carbon black ash or conductive carbon fiber is contained within 15 parts by weight (wt,%), It is provided by mixing a predetermined weight part suitable for the electrical characteristics desired by the consumer.

In the present invention, the original plate (also referred to as the original plate, hereinafter referred to as the original plate) for providing the heat generating means in the configuration of the planar heating element is provided by thermoforming in the form of a sheet or film using the above-mentioned conductive resin material compound.

The general feature of the preferred embodiment of the disc (sheet or film) of the heating means is about 0.2 to 5 mm in thickness; A specific gravity of about 0.9 to 1.1 g / cc and a prick strength of 150 kg / cm 2 or more based on the "JISK 6732" test method; The surface resistance is based on the "ASTM-D-257 test" method, and has an electrical resistance value of several to several hundred kV depending on the mixing ratio, within a weight part of 15 (wt,%) of carbon black.

For reference, in the planar heating element in which a heat generating film layer is formed by using a heat generating paint on a conventional resin material sheet, the surface resistance of the film forming layer of the heat generating means is about tens to hundreds of kPa (mostly about 50 to 500 kW / sq). , Some of which may be about 700 kW / sq, but may be almost 500 kW / sq or less). The electrical resistance value of the present invention is about several to several hundreds of times, and the heat generating means of the present invention is several to several hundreds of kW.

In fact, the silver powder is most commonly used in the electronic industry because of its high conductivity and chemical stability.

In addition, although the conductive for screen printing is called ink in the market, although there is no clear distinction between conductive ink and conductive paint, the term ink is mainly used for screen printing, but in the detailed description of the present invention, it will be referred to collectively as conductive paste material. do.
