Due to the processing, it is very easily scratched and the black appearance is significantly impaired. Furthermore, rust develops from the scratched areas, producing white corrosion products, which impairs the beautiful black appearance. Further, according to method (2), since it is necessary to hide the base color, a coating film thickness of 15 μm or more is usually required, and there are problems such as an increase in coating costs.

。In the black plated tone plate according to the present invention, a black film is provided as a first layer on the galvanized tone plate and the zinc-based alloy plated steel sheet by a chemical conversion treatment method. Method of immersion in chlorate, molybdate, anhydrous chromic acid, sulfide or sulfate steel solutions.

等があるが、これら以外の化成処理法を使用することも
できる。etc., but chemical conversion treatment methods other than these can also be used.
この化成処理法により得られた黒色皮膜は、未だ耐摩耗
性や加工性が劣っており、傷がつき易い。The black film obtained by this chemical conversion treatment method still has poor wear resistance and processability, and is easily scratched.
従って、第２層としてこの化成処理法により設けられた
黒色皮膜の第１層の上に塗布型クロメート皮膜を設ける
。Therefore, a coated chromate film is provided as a second layer on the first layer of the black film provided by this chemical conversion treatment method.

びａ１ｍ添加剤を含有した溶液を塗布後、乾燥して設け

膜を形成する反応型クロメート皮膜とは異なっている。This coated chromate film is a film that is formed by applying a solution containing chromic acid, a silicate compound, and an A1M additive and then drying it, and is different from a reactive chromate film that forms a chromate film while etching the surface. There is.

、この第２層のクロメート皮膜の上に設ける樹脂皮膜の
密着性を向上させる効果があり、皮膜量はクロム量で０
．０１〜Ｉｇ／ｉ’の範囲とするのがよい。This chromate film has the effect of improving corrosion resistance and also improving the adhesion of the resin film provided on the second layer of chromate film, and the amount of the film is 0 in terms of chromium content.
．． The range is preferably from 01 to Ig/i'.
この第２層のクロメート皮膜の上に、第３層として黒色
顔料を２〜ｌ８ｗｔ％含有する樹脂皮膜を塗布した後、
乾燥、硬化させて１〜７μｍの厚さの塗膜を設ける。After applying a resin film containing 2 to 18 wt% of black pigment as a third layer on this second layer of chromate film,
It is dried and cured to form a coating film with a thickness of 1 to 7 μm.

ると共に耐蝕性を向上させる効果がある。This coating itself is a black coating, and in combination with the first layer of black chemical conversion coating, provides a uniform and stable black appearance. It also protects the black chemical conversion coating,
In particular, it has the effect of preventing whitening after processing, improving black appearance, and improving corrosion resistance.

ある。The resins used for this paint are solvent-diluted types such as epoxy, polyester, acrylic, melamine, urethane, and silicone, or acrylic-styrene, epoxy ester, acrylic, urethane, and polyacetic acid. Aqueous emulsion types such as vinyl, boethylene, and ethylene vinyl acetate may be selected. However, when a water-based emulsion type paint becomes thick, it is difficult to dry and harden it in a short period of time, so it is advantageous to use a solvent diluted type paint.

。Further, as the black pigment, it is preferable to use carbon black, but it is not particularly limited. If the content of this black pigment is less than 2wt%, the hiding power will be poor and the degree of blackness will decrease, making it impossible to achieve the purpose.If the content exceeds 10wt%, the dispersion of the pigment in the paint will become unstable. hand,
It tends to agglomerate, making it difficult to apply a thin and uniform coating.
さらに、体質顔料として防錆顔料を添加すると耐蝕性は
より一層向上する。その他、目的に応じて各種添加剤を
使用することも可能である。Furthermore, when an anti-rust pigment is added as an extender pigment, the corrosion resistance is further improved. In addition, it is also possible to use various additives depending on the purpose.
樹脂皮膜の厚さは１μｍ未満では黒色度が不足し、下層
皮膜を保護する効果が少なく、目的を達成することがで
きず、また、７μｍを越える厚さではこの効果は飽和し
てしまい、経済的に無駄である。If the thickness of the resin film is less than 1 μm, the blackness will be insufficient, and the effect of protecting the underlying film will be small, making it impossible to achieve the purpose. If the thickness exceeds 7 μm, this effect will be saturated, making it economically difficult. It's a waste of time.
