産業上の利用分野
本発明は、電気エネルギーを利用する面状発熱体に関す

熱源、とくに輻射加熱源を提供するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a planar heating element that utilizes electrical energy, and is suitable for use as a heat source for heat utilization equipment such as heaters, cookers, and dryers, particularly as a radiant heating source. This is what we provide.
詳しくは、蛇行状、渦巻き状など所望回路状に形成した
面状発熱体を耐熱性プリプレグに取付は加熱圧着してな
る面状発熱体に関するものである。Specifically, the present invention relates to a sheet heating element formed by forming a desired circuit shape such as a meandering shape or a spiral shape and attaching the sheet heating element to a heat-resistant prepreg by heat-pressing.
従来の技術
従来の面状発熱体の多くは、マイカなどの絶縁基板に電
熱線を巻回した構造のものが用いられている。2. Description of the Related Art Most conventional planar heating elements have a structure in which a heating wire is wound around an insulating substrate made of mica or the like.
また最近では、アルミナ等の陶磁器質焼成ブロック中に
導電回路を所望形状に埋設した面状発熱体もある。Recently, there are also planar heating elements in which a conductive circuit is embedded in a desired shape in a ceramic firing block such as alumina.

ル、ステンレススチール、鉄等の面状金属発熱体の片面
若しくは両面にポリエヌテルフィルム、ポリイミドフィ
ルム、ポリカーボネートフィルム等の合成樹脂絶縁フィ
ルムを接着したものが広く採用されている。Furthermore, a planar heating element has been proposed in which a planar heating conductor covered with an enamel layer is bonded to a metal substrate for enameling. (For example, Japanese Unexamined Patent Publication No. 60-25176) Other examples of this type of sheet heating element include sheet heating elements made of aluminum, copper, nickel, stainless steel, iron, etc., formed into a desired circuit shape such as a meandering or spiral shape. A metal heating element in which a synthetic resin insulating film such as a polyester film, a polyimide film, or a polycarbonate film is adhered to one or both sides is widely used.
発明が解決しようとする問題点
しかしながら、従来の技術では、以下のような問題があ
った。Problems to be Solved by the Invention However, the conventional technology has the following problems.
マイカヒータの場合は、電熱線を基板に巻回するのに手
間がかかる上に、マイカと電熱線との接触が悪くなると
電熱線が空焼きされ高温になり断線し易く、また、電熱
線が封口されていないため、耐湿性に問題があった。In the case of mica heaters, it is time-consuming to wind the heating wire around the board, and if the contact between the mica and the heating wire deteriorates, the heating wire is air-baked and reaches a high temperature, making it easy to break. There were problems with moisture resistance.
次に陶磁器を用いるヒータの場合には、陶磁器焼成ブロ
ックの機械的強度が低く、厚みが厚くなって熱容量が大
きくなるため速熱性が悪く、また焼結温度が高いため、
接点材料の酸化・溶融などにより、電極の取出しに問題
があった。Next, in the case of heaters using ceramics, the mechanical strength of the ceramic firing block is low, the thickness increases and the heat capacity increases, so the heating speed is poor, and the sintering temperature is high.
There were problems in removing the electrodes due to oxidation and melting of the contact material.
更にホウロウヒータの場合には、その製造方法が極めて
複雑で手間がかかる土に、ホウロウ層の電気絶縁性の観
点からすると、ホウロウ層を緻密に、Ｎａ、になどのア
ルカリ分ヲ少なく、ホウロウ層の厚みを厚くすることが
望ましいが、逆に耐熱性の面では耐熱性が低下する方向
となシ、両者のバランヌを考慮すると３００°Ｃ以上の
高温での使用は困難であった。Furthermore, in the case of enamel heaters, the manufacturing method is extremely complicated and time-consuming.From the viewpoint of electrical insulation of the enamel layer, the enamel layer is made dense, has low alkali content such as Na, It is desirable to increase the thickness of the material, but on the other hand, in terms of heat resistance, this tends to decrease the heat resistance.Considering the balanne of both, it has been difficult to use it at high temperatures of 300°C or higher.
また、シリコーン樹脂、ポリイミド樹脂などのフィルム
を用いるヒータの場合には、その使用温度が絶縁フィル
ムに損傷をきたす欠点があった。Furthermore, in the case of a heater using a film made of silicone resin, polyimide resin, or the like, there is a drawback that the operating temperature damages the insulating film.

いる。The present invention solves these conventional problems, and by providing a heat-resistant prepreg containing a borosiloxane polymer on at least one side of the metal heating element, it can be used satisfactorily even in an atmosphere of 400 to 500 degrees Celsius, and the space required is extremely small. The purpose is to provide a compact planar heating element.
また、生産性に優れ、安価に製造できる面状発熱体を提
供することも本発明の目的である。Another object of the present invention is to provide a planar heating element that has excellent productivity and can be manufactured at low cost.

なることを特徴としている。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a heat-resistant sheet heating element formed by hot-pressing a heat-resistant prepreg on one or both sides of a metal heating element formed into a desired circuit shape. Pre-preg is made by impregnating a heat-resistant base material with a heat-resistant resin containing at least 10% by weight of a borosiloxane polymer and baking it under appropriate conditions to remove the bonds between silicon-alkyl groups or silicon-phenyl groups in the borosiloxane polymer. It is characterized by being decomposed in an appropriate amount.

望ましい。In addition, the borosiloxane polymer in the present invention includes:
Any polymer compound having silicon, oxygen, or boron as its main skeleton can be used. However, from the viewpoint of heat resistance, etc., dimethyl silicone oil and methylphenyp silicone oil are especially recommended! It is desirable to use a polymer obtained by condensation polymerization of a hydroxysilane such as diphenyldihydroxysilane or dimethyldihydroxysilane, and a boric acid compound using Unashi IJ corn oil/l/ as a solvent.

本発明において耐熱性樹脂に対するボロシロキサン重合
体の含有量を少なくとも１０重ｆｉ％と限定したのは、
１０重量％未満ではポロシロキサン重合体の耐熱効果を
充分発揮できず、耐熱性に問題があるためである。In the present invention, the content of the borosiloxane polymer in the heat-resistant resin is limited to at least 10% by weight.
This is because if the amount is less than 10% by weight, the heat resistance effect of the polysiloxane polymer cannot be sufficiently exhibited and there is a problem in heat resistance.
尚、ポロシロキサン樹脂を含む耐熱性樹脂には各種充填
剤および着色顔料等の併用も可能である。In addition, various fillers and coloring pigments can be used in combination with the heat-resistant resin containing the polysiloxane resin.

熱乾燥温度は２００〜３００℃が好ましく、その理由は
ポロシロキサン重合体の加熱乾燥が不十分な場合も過度
に加熱乾燥した場合にも自己接着性および基体への接着
性が悪くなるためである。In addition, in the present invention, the heat-drying temperature of such a heat-resistant base material impregnated with a heat-resistant resin containing a polysiloxane polymer is preferably 200 to 300°C, because the heat-drying temperature of the polysiloxane polymer is This is because the self-adhesiveness and adhesion to the substrate will deteriorate if the heat-drying is insufficient or excessively heated.

に優れたものが得られる。Therefore, it is preferable to determine the temperature conditions during heat drying so that the silicon-alkyl group or silicon-phenyl group bond is decomposed by an appropriate amount. The heading indicates that this condition falls within the range of ■ shown in Figure 2. (Conditions in the range I result in excessive heat drying; conditions in the range ■ result in insufficient heat drying.) Therefore, for heat drying, the
By performing heating and drying at a temperature of . . . and for an appropriate time within the range of . . . in the drawing, a prepreg with excellent properties can be obtained.
しかしながら、生産炉で連続的に長尺物を乾燥する場合
には当然、炉の温度は一定でなくある分布をもっておシ
適正加熱条件はバッチ式と異なって来るため、前記条件
に制約されるものではない。However, when continuously drying long objects in a production furnace, the temperature of the furnace is not constant, but has a certain distribution, and the appropriate heating conditions are different from those of the batch method, so the conditions are limited. isn't it.

Adhesion strength between metal heating element and heat-resistant prepreg is 400~s
Since it has a sufficiently high o o 'c, it can be used as a sheet heating element at 400 to 500°C. Furthermore, since the heat capacity is small, the temperature rises quickly, and it has the advantage that it is thin and can be designed into various shapes. Since the metal heating element is bonded with heat-resistant prepreg, it is highly reliable as it will not deteriorate due to dry firing or water vapor.
