本発明は鉄素地表面に耐蝕非粘着性塗膜を形成する方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a corrosion-resistant, non-adhesive coating on the surface of a ferrous substrate.
従来、鉄素地に弗素樹脂塗膜を形成するに当っては、そ
の上に直接弗素樹脂を塗布、焼付けて行っているが、こ
の場合弗素樹脂が多孔質のものであるが故に耐蝕性が向
上されず、鉄素地の腐蝕が容易に進行してひいては塗膜
剥離を来す原因ともなっていた。Conventionally, when forming a fluororesin coating on an iron base, the fluororesin is applied directly onto it and baked, but in this case, the fluororesin is porous, which improves corrosion resistance. Otherwise, corrosion of the iron base easily progressed, which in turn caused the paint film to peel off.
そのため、従来は家庭用厨房器具等にこの種樹脂加工を
利用する場合にあっては、鉄素材は用いず、専らアルミ
ニウムのような耐蝕素材を代替的に使用しているのが実
情である。For this reason, conventionally, when using this type of resin processing for household kitchen appliances, iron materials are not used, and corrosion-resistant materials such as aluminum are used instead.
しかして、本発明はかかる困難性を克服解消して、鉄素

なる点にある。Therefore, the present invention has been made for the purpose of overcoming these difficulties and providing a new method for forming this type of corrosion-resistant, non-adhesive coating film on iron substrates. The characteristics are a step of forming an enamel film on the iron base, a step of roughening the surface of the enamel film,
The method consists of a step of spraying high-purity aluminum onto the roughened enamel film surface to form an aluminum film, and a step of applying a fluororesin to the aluminum film surface and firing it.

ることを特徴とするものである。In other words, it has been widely practiced to form an enamel film on an iron substrate, but even if a fluororesin is applied to the enamel surface or a roughened enamel surface and fired, there will be no separation between the enamel and the fluororesin. The problem remains that the adhesive strength is low and it easily peels off, making it unsuitable for practical use.The present invention aims to prevent this problem by applying and baking a fluororesin using an aluminum film that has good adhesion to enamel as a medium. It is characterized by:
以下本発明をその工程順に詳しく説明する。The present invention will be explained in detail below in the order of its steps.
第１工程 目的物品の鉄素地にホウロウ皮膜を形成する。1st step An enamel film is formed on the iron base of the target article.
この際のホウロウ施工法には別設特色なく、既知の手段
がそのまま適用され、乾式法、湿式法の種別を問わない
。The enamel construction method at this time has no special features, and known means are applied as is, regardless of whether it is a dry method or a wet method.
なお、ホウロウの膜厚は１５〜２００μの程度が適当で
ある。Note that the appropriate thickness of the enamel film is about 15 to 200 μm.
すなわち、上記下限以下の厚みでは、次工程において表

ウロウ皮膜にクラックを起生ずるおそれが生じるためで
ある。In other words, if the thickness is below the above lower limit, there is a risk that the iron base will be exposed when the surface is roughened in the next step and the corrosion resistance will be impaired.On the other hand, if the thickness is above the above upper limit, cracks will occur in the enamel film. This is because there is a risk of this happening.
第２工程
ホウロウ表面をその密着性を高めるべ（ブラスト等の適
宜手段によって粗面化する。Second step: The surface of the enamel is roughened by appropriate means such as blasting to increase its adhesion.
この際の表面粗さは８〜１５μの程度が適当である。The appropriate surface roughness at this time is about 8 to 15 microns.
第３工程

ウムを熔射して：膜厚１０〜５０μの程度好ましくは２
０μ前後のアルミニウム皮膜を形成する。Third step: Spray high-purity aluminum onto the roughened enamel film surface to a film thickness of 10 to 50 μm, preferably 2 μm.
Forms an aluminum film with a thickness of around 0μ.
この際、溶射には耐蝕性を確保する見地より純度の高い
ものを使用する必要があり、望ましくは純度９９％以上
のアルミニウムを使用する。At this time, it is necessary to use a material of high purity for thermal spraying in order to ensure corrosion resistance, and preferably aluminum with a purity of 99% or more is used.
