田強度（以下、半田性と略す）、耐食性。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to post-treatment of steel plates for soldering, and improves solder spread, solder strength (hereinafter abbreviated as solderability), and corrosion resistance.
加工性および経時性に優れた後処理方法に関する。This invention relates to a post-processing method with excellent workability and aging properties.
近年、半田の可能な鋼板として、Ｓｎめっき鋼板。 In recent years, Sn-plated steel sheets have become popular as solderable steel sheets.
Ｐｂ−８ｎめっき鋼板、 Ｃｕめっき鋼板およびＺｎめ

しなければ実用上問題となる。Rust occurs. Therefore, in order to improve corrosion resistance, chemical conversion treatments such as chromate treatment and phosphate treatment, or temporary application of rust preventive agents, etc., are performed. In the case of chromate treatment, C2 is replaced with Cr to improve corrosion resistance.
1mg/dm or more is required, but if chromate treatment is applied, the solderability will drop significantly, and if it becomes 0.05■1 drd or more, it will become a practical problem unless a strong corrosive flux is used during soldering. .

おり、十分な耐食性が得られない。ま□た。If a highly corrosive flux is used, it will create a poor environment during soldering work and will significantly reduce the corrosion resistance of the soldered parts. Therefore, Cr is suppressed to 0.05 ■Idrd or less, and sufficient corrosion resistance cannot be obtained. It was.
一時防錆剤を塗布する方法では、クロメート処理の場合
と同様に半田性を低下させる場合がある。The method of temporarily applying a rust preventive agent may reduce solderability as in the case of chromate treatment.
しかも半田を施した後の耐食性は著しく劣る。Moreover, the corrosion resistance after soldering is significantly inferior.

し、公知の後処理方法では。As mentioned above, in order to obtain a soldering steel plate with excellent properties, it is necessary to perform post-treatment after plating to improve corrosion resistance without damaging the semi-I' properties of the plated steel plate. However, with known post-processing methods.

田の隠れを悪くすることが原因と考えられる。Since improvements in solderability and corrosion resistance tend to contradict each other, it is difficult to obtain a steel plate with a good balance between corrosion resistance and solderability. This tendency becomes noticeable (= appears) as the plated steel sheet ages. In other words, the cause is thought to be that over time, an oxide film grows on the plating surface, making it difficult to hide the solder.
したがって、めっき後の後処理の改善が必要である。Therefore, there is a need for improved post-treatment after plating.

処理することを特徴とする。According to the present invention (2), post-treatment after plating includes 5 to 200 get of water-soluble or water-dispersible phosphate ester salt or 0.01 to 3 g of Cr6+ ion + 10 to 100 get of organic amine/soap. It is characterized by treating a plated steel plate with a treatment solution of I) H3 to 10 containing either alone or a mixture thereof so that the dry thickness becomes 0.01 to 2 μm.
以下９本発明の詳細な説明する。Hereinafter, nine aspects of the present invention will be described in detail.

とができる。The water-soluble or water-dispersible phosphoric acid ester salt, which is the main component in the present invention (2), is in the form of a basic or dibasic acid with one or two alkyl groups, or in the form of an organic amine. Also, if the alkyl group is large and is insoluble in water, it can be used as an alkali salt or added with ethylene oxide to increase its hydrophilicity.
前述の濃度が適正濃度以下の場合は半田性の効果は認め
られない。適正濃度以上になると半田性の効果は飽和し
、乾燥が悪くなる。If the aforementioned concentration is below the appropriate concentration, no solderability effect will be observed. When the concentration exceeds the appropriate concentration, the solderability effect is saturated and drying becomes worse.

端（二低下するので好ましくない。In order to stabilize the treatment solution or to improve the corrosion resistance and scratch resistance of the plated steel sheet, add Cr6+ or organic amine soap alone or in combination. If this happens, the solderability will be extremely low, which is undesirable.

好ましくない。Organic amine soaps include dodecylamine, oleoyl imidapurine, aminopropyl tallow amine, and rosin amine, and amines can be used by forming salts with carboxylic acids. If the concentration is 100 g/1 or more C2, an effect on corrosion resistance can be seen, but solderability is deteriorated, which is not preferable.
そのほかに公知の水溶性あるいは水分散性の防錆剤を添

この場合、半田性を低下させるものがあるので添加量に
は注意する必要がある。たとえば、アクリルエマルジョ
ンを添加すると耐疵つき性は向上するが、半田性は低下
する。In this case, it is necessary to be careful about the amount added since some of them reduce solderability. For example, adding an acrylic emulsion improves scratch resistance but reduces solderability.
処理液のＰＨは３〜１０の範囲が適当である。３以下の
場合は処理液の安定性が悪く、１０以上になると処理皮
膜の乾燥性が悪い。The pH of the treatment liquid is suitably in the range of 3 to 10. If it is 3 or less, the stability of the treatment liquid is poor, and if it is 10 or more, the drying properties of the treated film are poor.
処理液の温度は特ζ二制限されないが８０℃以上になる
とゲル化し処理液の安定性を悪くするものがあり１通常
は２０〜４０℃が経済的である。The temperature of the processing liquid is not particularly limited, but if it exceeds 80°C, it may gel and deteriorate the stability of the processing liquid, so 20 to 40°C is usually economical.
塗布方法はロールコート、ナイフコート、浸漬後ロール

好ましくない。Drying is not a problem as long as it is not sticky to the touch, but if moisture remains, it is undesirable as it can cause rust over time.
後処理皮膜の乾燥厚みは０．０１〜２μｍが適当である
。００１μｍ以下の場合は特性の効果が認められない。The dry thickness of the post-treated film is suitably 0.01 to 2 μm. If the thickness is less than 0.001 μm, no effect on the characteristics is observed.

When applied to the surface of a plated steel plate or Zn-plated steel plate,
The result is not only improved solderability but also markedly improved corrosion resistance. Furthermore, the plated steel sheet has excellent solderability and corrosion resistance after aging. The steel plate to be coated is not limited to the above-mentioned plated steel plate.

考えられる。The reason why the properties improve in this way is not clear, but the post-treatment of the present invention suppresses the formation of oxides, hydroxides, and carbonates on the plated surface. The coating film of the present invention dissolves metal compounds on the plating surface by heating during soldering, and some of them are reduced, so that solder wetting and
It is thought that diffusion is promoted and solderability is improved. Further, due to the above-mentioned phenomenon, the coating film of the present invention uniformly covers the plated surface (1), which is thought to improve the corrosion resistance.

１．０００時間時間後の外観（変色）を観察し、さらに
前述の試験で耐食性、半田性を評価した。○：変色なし
×：全面変色
化成処理としてクロメート処理およびりん酸処理を施し
たが、耐食性に対して効果が認められるものは半田性で
半田の濡れが悪く、劣る傾向な示した。また、経時する
ことによって９表面の色調は変化し、耐食性も低下する
傾向を示した。The appearance (discoloration) after 1,000 hours was observed, and the corrosion resistance and solderability were further evaluated using the aforementioned tests. ○: No discoloration ×: Full-surface discoloration Chromate treatment and phosphoric acid treatment were performed as chemical conversion treatments, but those that were found to be effective for corrosion resistance showed poor solderability and poor solder wetting. Moreover, the color tone of the surface of 9 changed over time, and the corrosion resistance also tended to decrease.
第１表、第２表の実施例１〜６に示したように。 As shown in Examples 1 to 6 in Tables 1 and 2.
本発明の方法によって、耐食性、半田性、加工性。Corrosion resistance, solderability, and processability can be improved by the method of the present invention.
経時性（１優れためつき鋼板を得ることができた。A steel plate with excellent aging properties (1) could be obtained.
