本発明は、複写機の定着部に使用されるヒートロールの
製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a heat roll used in a fixing section of a copying machine.
従来よりヒートロールには、加熱硬化型
（ＨＴＶ）又は常温硬化型（ＲＴＶ）シリコーンゴムが
使用されているが、ＨＴＶシリコーンゴムはシリコーン
オイルの含有量が少ないため、ＨＴＶシリコーンゴムか
ら成るヒートロールは離型性に劣り、しかも電気抵抗が
高く、帯電による紙の巻き付きが生じやすいという欠点
があった。Conventionally, heat cure type (HTV) or room temperature cure type (RTV) silicone rubber has been used for heat rolls, but since HTV silicone rubber has a low silicone oil content, heat rolls made of HTV silicone rubber are It has the drawbacks of poor mold releasability, high electrical resistance, and the tendency for paper to wrap around due to charging.

が小さいため傷がつきやすいという欠点があり、いずれ
もヒートロールの寿命が短いという難点があった。In addition, heat rolls made of RTV silicone rubber have the disadvantages that silicone oil, which is pre-blended as a mold release agent, easily escapes from the rubber, making it easy to offset, and also being easy to scratch because of its low strength. The problem was that the heat roll had a short lifespan.
このため、ＨＴＶシリコーンゴムの場合は加熱硬化後、
シリコーンオイル中に浸漬して離型性を改善する試みが
なされているが、この場合浸漬後にロール中央部がタイ
コ状に膨潤したりするので、生産性に劣るという難点が
あった。For this reason, in the case of HTV silicone rubber, after heat curing,
Attempts have been made to improve the releasability by dipping the roll in silicone oil, but in this case, the central part of the roll swells in a cylindrical shape after dipping, resulting in poor productivity.
本発明者らはこのような難点に鑑み、鋭意研究をすすめ

た。In view of these difficulties, the present inventors conducted intensive research and found that they adopted a method of dipping a heat roll made of RTV silicone rubber in silicone oil, which had been tried in the case of HTV silicone rubber.
It has been found that the phenomenon of swelling seen in the case of V silicone rubber does not occur, and it has the advantage that the silicone oil blended as a release agent is difficult to come off.

イルの粘度より小さいものの方が良好である。In the present invention, the silicone oil to be immersed after curing may be either methylphenylpolysiloxane or dimethylpolysiloxane, but it is better if the viscosity is lower than that of the silicone oil to be blended.
浸漬処理を施こすことによりゴムの重量が変化して一定
になることから、浸漬によりゴムの内部で油の置換が行
なわれて安定化し、油がゴムから抜けにくくなるものと
考えられる。Since the weight of the rubber changes and remains constant through the dipping treatment, it is thought that dipping replaces oil within the rubber, stabilizes it, and makes it difficult for oil to escape from the rubber.
浸漬温度と浸漬時間は適宜実験により、ゴムの重量が一
定になる条件から決定される。The immersion temperature and immersion time are determined by appropriate experiments based on the conditions under which the weight of the rubber remains constant.
ちなみに１８０℃の場合は１〜３日が適切である。Incidentally, in the case of 180°C, 1 to 3 days is appropriate.
