法により行なわれてν・る。(Prior Art) In recent years, a ceramic film has been formed on a steel plate to improve the heat resistance, corrosion resistance, abrasion resistance, far-infrared radiation characteristics, etc. of the steel plate. This ceramic coating is formed by coating a steel plate with a ceramic paste paint or a ceramic coating and then firing it at commercial temperature.

The desired shape could not be processed due to peeling. For this reason, the formation of the ceramic film had to be carried out by processing the steel plate into the desired shape (applying paste paint or 7Lite and firing it. However, this method (especially manufacturing efficiency) Because it is very low, the cost was only 1 piece.Also, when fired at high temperature after processing,

Then, the formation of this methyl silicone resin film on the steel plate is carried out by adding metal powder with an average particle size of 0.01 to 5 μm to an alcohol solution containing 1% by weight or more of monomethyltrialfukidisilane.
After applying the additive solution to the steel plate surface, it is heated at a temperature exceeding 150°C to form a silicone resin film containing metal powder.
The thickness was set to 15 μm.

ポリマーは、線状ポリマーであるため、皮膜の密着性が
劣るためである。(Function) The reason why the silicone resin film formed on the steel sheet in the present invention is made of methyl silicone resin is that when the furkyl group bonded to Si has two or more carbon atoms, the heat resistance increases as the number of carbon atoms increases. decreases, and is also trimethyl silicone resin,
This is because the polymer is a linear polymer, so the adhesion of the film is poor.
メチルシリコン樹脂皮膜は、金属粉末を含有させると、
無添加の場合より皮膜硬度が高くなる。When the methyl silicone resin film contains metal powder,
The film hardness is higher than that without additives.
しかし、それにも拘わらず皮膜の加工性は向上する。こ
の理由については明確でないが、次のような理由が掲げ
られる。However, the processability of the film is improved despite this. Although the reason for this is not clear, the following reasons can be cited.
（１）金属粉末はメチルシリコン樹脂皮膜自体より延性
に冨んでいるため、皮膜に延性が付与される。(1) Since the metal powder is more ductile than the methyl silicone resin coating itself, it imparts ductility to the coating.
（２）加工の際、皮膜にかかる応力を金属粉末が緩和す
る。(2) Metal powder relieves the stress applied to the film during processing.
（３）金属粉末の熱膨張係数は、鋼板と近似しているた
め、溶液皮膜を加熱して樹脂皮膜にする際皮膜に発生す
る残留応力が少なくなり、加工してもクラックが発生し
にくくなる。(3) The coefficient of thermal expansion of metal powder is similar to that of steel sheets, so when a solution film is heated to form a resin film, the residual stress generated in the film is reduced, making it difficult for cracks to occur during processing. .
（４）金属粉末は、無機酸化物に比較して、加工時に皮
膜に生じる応力を緩和したり、クラックの進展を防止し
たりする効果が大きい。(4) Metal powder has a greater effect than inorganic oxides in alleviating stress generated in the film during processing and preventing the development of cracks.

粉末が好ましい。This metal powder may be a single metal or an alloy. This metal powder is preferably H8, N1, Fe,
Zn, ^1, Cu, W, Zn-^1, Cu Z
n. There are powders made of stainless steel, etc., but consider corrosion resistance! In this case, powders of Ni, ^1, Zn-^I, stainless steel, etc. are preferred.
金属粉末は、導電性を有しているため、セラミックス皮
膜やメチルシリコン樹脂皮膜自体より電気抵抗溶接性に
優れ、スポット溶接が可能である。Since the metal powder has electrical conductivity, it has better electric resistance weldability than the ceramic film or methyl silicone resin film itself, and spot welding is possible.
金属粉末の皮膜中への含有量は、１〜２０重量％にする
のが好ましい、これは、金属粉末が１重量％未満である
と、加工性や溶接性が十分でなく、２０重量％より多く
すると、皮膜の加工性が低下してしまうからである。The content of the metal powder in the film is preferably 1 to 20% by weight. This is because if the metal powder is less than 1% by weight, workability and weldability are insufficient, and the content is less than 20% by weight. This is because if the amount is increased, the processability of the film will deteriorate.
皮膜厚は１〜１５μｍにする、１μ輪未満であると、耐
熱性、耐食性が劣り、１５μ箇を越えると、クラ７りや
剥離が生じ易くなる。The film thickness should be 1 to 15 μm. If the thickness is less than 1 μm, the heat resistance and corrosion resistance will be poor, and if it exceeds 15 μm, cracking or peeling will easily occur.

形成される。The methylsilicon resin film is formed using an alcoholic solution of monomethyltrialkoxysilane with metal powder added. After applying this solution to a steel plate and hydrolyzing it with moisture in the air to form silanol, or before application. Add water and an acid or alkali as necessary to the solution to hydrolyze it to form a sila 7-al, and the sila 7-
When the steel plate is heated after the silanol is applied to the steel plate, the silanol is dehydrated and condensed to form a methyl silicone resin film with a three-dimensional structure.

径が０．０１μｍ未満の微粒子にすると、＾優になり、
５μｍを超えるものにすると、皮膜中に分散しにくく、
加工性も悪くなるためである。The concentration of monomethylalkoxysilane is set to 1% by weight or more in order to make the film after heating 1 μm thick or more. Further, as the alcohol to be dissolved, lower alcohols having a low boiling point and being inexpensive are preferable. Further, the metal powder to be added should have a particle size of 0.01 to 5 μm. This becomes excellent when fine particles with an average particle size of less than 0.01 μm are used.
If it exceeds 5 μm, it will be difficult to disperse in the film,
This is because processability also deteriorates.
溶液の鋼板への塗布は、公知方法、例えば、ロールコー
ト法、スプレー法、浸漬法などで均一に。The solution is uniformly applied to the steel plate using known methods such as roll coating, spraying, and dipping.

しい。A good film will be formed if the heating temperature exceeds 150°C, but in order to suppress the bumping of the alcohol in the solvent, it is preferable to keep it below 450°C. The heating temperature is preferably set according to the purpose of use, since the film is soft and has good workability.

A steel plate (for example, a steel plate, a Cu-plated steel plate, a Zn-plated steel plate, etc.) may be selected.
