本発明は、金属やセラミック等の母材の表面に面状発熱
体を焼付けする面状発熱体の形成方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method of forming a sheet heating element by baking the sheet heating element onto the surface of a base material such as metal or ceramic.
従来より多く利用されている面状発熱体は、細いニクロ

ルなど絶縁性シートで挾持されｆｃ＃Ｊのが、各種暖房
機器や電熱機器に利用されている。Planar heating elements, which have been widely used in the past, are made by forming a metal material such as thin nichrome wire into a planar shape, and sandwiching both sides of the sheet with an insulating sheet such as vinyl chloride. Used in electric heating equipment.
しかしながら、このような面状発熱体は、単位面積当シ

も悪い。However, such planar heating elements cannot be designed with the resistance value per unit area taken into account, and there are problems such as disconnection of the nichrome wire, and problems such as poor insulation in wet environments such as submerged in liquid. , it has the disadvantage of poor durability. Furthermore, when assembling the main body of the device, it is necessary to separately prepare a planar heating element and then assemble it by holding it in the main body, which results in poor workability.
このため、ニクロム線に代シ、発熱体としてカーボンコ

塩化ビニールシートやセラミックを取付けて表面絶縁し
ている。For this reason, a planar heating element using a carbon coating layer as a heating element has been developed instead of a nichrome wire. This involves attaching a vinyl chloride sheet or ceramic to the surface of the carbon coating layer on which the electrodes are attached to insulate the surface.
しかしながら、積層構造であるため、絶縁層とカーボン
コーティング層との密着性、水密性が確実でなく、特に
セラミックを溶射して絶縁層を形成したものは、表面が
多孔質であるので湿環境下で使用することができない。However, because of the laminated structure, the adhesion and watertightness between the insulating layer and the carbon coating layer are not reliable.In particular, the insulating layer formed by thermal spraying ceramic has a porous surface, so it cannot be used in a humid environment. cannot be used in
また従来の面状発熱体は、形状が平板状であるため、複
雑な曲面に取付けることができず、組込まれる機器も限
定されてしまう問題があっ友。Furthermore, because conventional planar heating elements have a flat shape, they cannot be installed on complex curved surfaces, and the devices they can be incorporated into are also limited.
本発明は、かかる従来の問題点に鑑みなされたもので、
取付は位置や形状、抵抗値の設定が容易である上、絶縁
性に優れ、液中でも使用でき、耐久性に優れている上、
機器と一体に形成するので、製造が容易な面状発熱体の
形成方法を提供するものである。The present invention was made in view of such conventional problems,
In addition to being easy to install, setting the position, shape, and resistance value, it has excellent insulation, can be used in liquids, and has excellent durability.
The present invention provides a method for forming a planar heating element that is easy to manufacture because it is formed integrally with a device.
以下、本発明方法を工程に従って詳細に説明する。 Hereinafter, the method of the present invention will be explained in detail according to the steps.
先ず、母材としては、例えばステンレス会合類、アルミ
ニウム合金類、あるいはホーロ用鋼板等の金属、または
陶磁器、ガラス、セメント耐火物、ファインセラミック
ス等のセラミックが用いられ、これら母材は板状に限ら
ず、容器状など何れの形状のものでも良い。First, as the base material, metals such as stainless steel aggregates, aluminum alloys, or steel plates for hollow holes, or ceramics such as ceramics, glass, cement refractories, and fine ceramics are used, and these base materials are limited to plate shapes. However, it may be of any shape, such as a container shape.
また母材として金属を用いる場合には、予め絶縁層を表

材金属よシ低い融点で焼成する。Further, when using metal as the base material, it is necessary to form an insulating layer on the surface in advance. In this case, in order to improve the adhesion with the base insulating layer, nickel, cobalt, manganese, etc. are attached to the surface, a base insulation/# (ground coat) is formed on this, and then KN surface insulation is formed on this. It is best to form a layer (cover coat). These insulating layers are made using a slip (glaze) mainly composed of glass frit and clay, which is applied to the surface of the metal base material, dried, and then fired at a melting point lower than that of the base metal.
なお、母材がセラミックの場合には、電気絶縁性がある
ので、特に表面に絶縁層を形成しなくても良い。Note that when the base material is ceramic, it has electrical insulation properties, so there is no particular need to form an insulating layer on the surface.
次に、母材の表面に、面状発熱体となる発熱体スリップ
（混合物）を回路パターンに形成謁。Next, a heating element slip (mixture) that will become a planar heating element is formed into a circuit pattern on the surface of the base material.
この発熱体スリップとしては、導電性粉末５〜６０重量
％、残部がガラススリットからなる混合物を用いる。As this heating element slip, a mixture consisting of 5 to 60% by weight of conductive powder and the remainder glass slits is used.
前記導電性粉末としては、例えば黒鉛、チタン、ジルコ
ニウム、チタン酸バリウムの粉末の何れか１種以上を単
独、または混合して用いる。As the conductive powder, for example, one or more of graphite, titanium, zirconium, and barium titanate powders may be used alone or in combination.
黒鉛は安価であるが多量に用いると焼付けした場合のガ
ラスエナメル質との密着性が悪くなもまたチタンは、ガ
ラスエナメル質との密着性に優れているが、高価である
ので、黒鉛と混合して用いると経済的である。Graphite is cheap, but if used in large quantities it has poor adhesion to glass enamel.Also, titanium has excellent adhesion to glass enamel, but is expensive, so it cannot be mixed with graphite. It is economical to use it.
また導電性粉末の混合物を上記の範囲に限定したのは、
５Ｎｋ％未満では、粉末同志の結合が悪く、十分な発熱
量が得られず、また６ｏ重ｉｔ％を越えて多量に添加す
ると、ガラスエナメル質の絶縁が低下する上、母材表面
から剥離し易くなるからである。なお、黒鉛とチタンを
用いた場合の望ましい範囲は黒鉛粉末２〜４０重スフリ
ットが最も効果的である。In addition, the reason why the conductive powder mixture is limited to the above range is that
If it is less than 5Nk%, the bond between the powders will be poor and sufficient calorific value will not be obtained.If it is added in a large amount exceeding 6Owt%, the insulation of the glass enamel will deteriorate and it will peel off from the surface of the base material. This is because it becomes easier. Note that when using graphite and titanium, the most effective range is 2 to 40-weight graphite powder.
なお混合する導電性粉末の粒度は１５０メツシュ以上、
特に３００〜５００メツシユが好ましく、粒度が大きい
と母材金ＩＩ４盾に接触して、絶縁不良を生ずることが
ある。The particle size of the conductive powder to be mixed is 150 mesh or more,
In particular, a mesh size of 300 to 500 is preferable; if the particle size is large, it may come into contact with the base metal gold II4 shield, resulting in poor insulation.

うに１表面に絶縁層、ｔａ、ｊｂを形成した金属母材乙
の上に貼付し、電極端子７．７を取付ける。In addition, methods for forming a heating element slip having the above composition by drawing a circuit pattern on the surface of the base material include transfer printing using transfer paper, screen printing, spray jetting, etc. ? <Form a turn. For example, in the case of using transfer paper, a circuit pattern 3 is formed on the surface of the paper with one heating element slip λ, as shown in FIG. 1, to create a transfer paper. As shown in FIG. 2, this is pasted onto a metal base material B having an insulating layer, ta, and jb formed on one surface, and an electrode terminal 7.7 is attached.
この後、加熱炉内に入れて母材融点以下の温度で焼付け
を行うと、面状発熱体が形成される。Thereafter, the sheet heating element is formed by placing it in a heating furnace and baking it at a temperature below the melting point of the base material.
この面状発熱体ｇは、第３図に示すように、例チタン粉
末１０がガラスエナメル層／／の表面側に埋設した状態
で、母材金属乙の表面に絶縁層５ａ、５ｂを介して形成
された状態となる。As shown in FIG. 3, this planar heating element g is constructed by placing titanium powder 10 embedded on the surface side of the glass enamel layer // on the surface of the base metal B through insulating layers 5a and 5b. It will be in a formed state.
従って、散在する黒鉛粉末９やチタン粉末１０同志の接
触状態によシ、所定の抵抗が得られ、電極端子７．７か
ら通電することにより、発熱することができる。Therefore, depending on the contact state of the scattered graphite powder 9 and titanium powder 10, a predetermined resistance can be obtained, and heat can be generated by applying electricity from the electrode terminals 7.7.
なお、導電性粉末として、チタン、ジルコニウムを用い

に母材金属が低融点金属の場合に好適である。Note that when titanium or zirconium is used as conductive powder, it will not become a resistor unless it is baked in an oxidizing atmosphere and oxidized, so it is necessary to set the baking temperature and time to the optimal conditions, but The baking temperature can be lowered by using titanium oxide or zirconium oxide, and this is particularly suitable when the base metal is a low melting point metal.
このように、発熱体スリップコで所望の回路パターン３

することができる。In this way, the desired circuit pattern 3 is created using the heating element slipco.
The method of forming the planar heating element g on the surface of the metal base material B using the transfer paper g formed with the metal base material B is superior in mass production and uniformity of resistance value, and is suitable for containers where the base material has a curved shape. etc., it can be widely formed.

ー噴射して１路パターンを形成する方法は、大型のもの
や少量生産する場合に好適な方法である。Note that the screen printing method is limited to cases where the base material is flat, but it is easy to adjust the resistance value (heat amount). Furthermore, the method of forming a one-way pattern by spraying the heating element slip while applying an appropriate mask is a suitable method for large-scale products or small-volume production.

ると良い。Furthermore, the terminals of the planar heating element are not limited to plate shapes; for example, the terminals may be formed by unraveling a core wire/2 made of twisted thin wires into a fan shape as shown in Figure 4, or by punching as shown in Figure 5. It is preferable to use a material that has a wide contact area with the planar heating element g, such as a metal material or a net-like material as shown in FIG. 6.
