せていた。Conventionally, in this type of apparatus, an indirectly heated metal chip is pressed against a work piece, as in the case of the crimping device for plastic members described in JP-A-57-195616.
In this example, the head of the thermoplastic resin rod protruding from the through hole of the base material is crushed by pressing a metal chip induction-heated with a high-frequency coil, and then a cooling fluid is flown inside the metal chip. The resin is cooled and solidified to fix the base material. Further, generally, a stainless steel chip is heated by mounting a cartridge cartridge heater. Cartridge heater
A metal heating element such as a nichrome wire is embedded in a metal cylinder together with an insulating powder such as magnesium oxide. In this case, the thermoplastic resin was softened by a heated chip, crushed, and then pressed by another cooling jig to be solidified.

The heating pin had to be indirectly heated using a corrosion resistant material. There is a technique described in Japanese Patent Application Laid-Open No. 59-26214, in which a heating element cover is not directly pressed against the resin but is brought into contact with a synthetic resin through a heating element cover made of a fluororesin so as to be laminated and joined.

触させず、間接的に加熱した高温部材を押しつけてい
た。このため、間接加熱なので部材を局所的に高温にす

温部材を強制的に冷却する、などの別の手段が必要であ
つた。In the above-mentioned conventional technique, the self-heating element is not directly contacted with the thermoplastic resin but is indirectly pressed against the heated high temperature member. For this reason, since it is indirect heating, the member cannot be locally heated to a high temperature, and there is a problem that the temperature rising rate of the contact portion is slow and the thermal efficiency is poor. Even if the heating is stopped, the temperature of the entire high-temperature member is still high, so the temperature does not drop immediately.To quickly solidify the melted or softened resin, use another cooling jig after softening. Other means such as pressing down, forcibly cooling the high temperature member, etc. were required.

必要としない樹脂加工用ヒータを提供することにある。An object of the present invention is to use a conductive ceramic having excellent high-temperature durability such as corrosion resistance, has fast heating property, can be directly contacted with a resin to be processed, has a long life, and does not require a means for cooling and solidification. It is to provide a heater for resin processing.

B2）といつた耐熱性の高い高融点化合物を用いる。In order to achieve the above-mentioned object, the heater for resin processing of the present invention is composed of conductive ceramics obtained by mixing and sintering a high-resistance member with a high-resistance ceramics and a low-resistance ceramics, which is energized to generate heat. Directly contact the resin of the work material. As the high resistance ceramic component, it is preferable to use silicon carbide (SiC), aluminum oxide (Al 2 O 3 ) or the like, which has excellent high temperature durability. The low-resistance ceramic components are zirconium boride (ZrB 2 ), titanium boride (Ti
B 2 ), hafnium boride (HfB 2 ), tantalum boride (Ta
B 2 ) and a high melting point compound with high heat resistance are used.

良好である。本発明は、このように新たに得られた知見
に基づいて、複合焼結体を採用したものである。Furthermore, as a result of various studies on the characteristics of such a composite sintered body, it was experimentally confirmed that the composite sintered body has excellent corrosion resistance at high temperatures and the characteristic deterioration due to contact with a resin is extremely small. Further, it was confirmed that the resin was easily separated from the sintered body in both the molten state and the solidified state while being in contact, and the workability was excellent. Further, this detachability is particularly good when the surface of the contact portion of the sintered body with the resin has a roughness of 1 μm or less. The present invention employs a composite sintered body based on the newly obtained knowledge.

く、寿命が長い。The composite sintered body used as the heater for resin processing of the present invention is superior in strength and oxidation resistance at high temperatures as compared with the metal used for the heater, as described above, and therefore, the workpiece to be processed while being energized. It can be pressed directly onto the resin. Therefore, unlike the indirect heating type, since the contact portion can locally generate heat to directly heat the resin, it is excellent in rapid heating property.
Moreover, since the temperature immediately drops when the power is turned off, the resin can be solidified while being pressed. Therefore, no separate cooling and solidifying means are required. Further, since the heat generating portion is brought into direct contact with the resin, heat does not escape in the middle unlike in the case of indirect heating, and the thermal efficiency is good. Further, since the heat-generating part made of the composite sintered body has excellent corrosion resistance and thermal shock resistance, there is almost no change in characteristics even after repeated use, and the life is long.

焼結していて樹脂が焼結体内部に侵入していかないため
と、セラミツクスの樹脂に対する濡れ性が悪いためと考
えられる。The reason why the composite sintered body used in the present invention has high conductivity is that zirconium boride, titanium boride, hafnium boride, and tantalum boride all have conductivity equivalent to that of metal. Since these compounds have high melting points and silicon carbide and aluminum oxide have high heat resistance, the composite sintered body also has excellent heat resistance. The reason why the composite sintered body has high strength and excellent oxidation resistance even at high temperatures is that it protects the boride component composed of silicon carbide and aluminum oxide. It is thought that the excellent corrosion resistance is due to the same reason. The reason why the resin is easily released is considered to be that the sintered body is densely sintered and the resin does not enter the inside of the sintered body, and the wettability of the ceramic with the resin is poor.

自己発熱する高温部材を構成する導電性セラミツクスに
は、回路形成のための構造に応じてさらに強度をもたせ
る目的で、絶縁性セラミツクスを一体化させることが望
ましい。It is desirable to integrate the insulating ceramics into the conductive ceramics that constitute the high-temperature member that self-heats, for the purpose of further increasing the strength according to the structure for forming a circuit.

ものとなるので特に有効である。As an example, a resin processing heater having a heat generating part made of a composite sintered body using silicon carbide as a high resistance ceramics component and zirconium boride as a low resistance ceramics component shows this feature remarkably. The use of aluminum nitride as the heat-resistant ceramic is particularly effective because it has a small difference in coefficient of thermal expansion from the composite sintered body and is excellent in thermal shock resistance.

することが望ましい。The composite sintered body used in the present invention can be manufactured by pressureless sintering or hot press sintering after mixing and molding raw material powders. At this time, by adjusting the compounding ratio of the high resistance ceramics component and the low resistance ceramics component, it is possible to obtain a sintered body having a resistivity suitable for the purpose. In addition, it is desirable to attach an auxiliary agent for promoting the sintering during the sintering.

This made it possible to fix the substrate by forming the rivet end into the shape of the depression of the heater tip. During this work, Ar gas was blown to the heating part to prevent the oxidation of aluminum as a non-oxidizing atmosphere.
