本発明はアルミめっき鋼板の表面処理方法に関するもの
で、溶融アルミめっき鋼板の有する美麗な銀白色光沢を
損なうことなく、苛酷な環境下においても、また加工部
においても優れた耐食性を有することを目的とした処理
方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for surface treatment of aluminized steel sheets, which provides excellent surface treatment even under harsh environments and in processed parts without impairing the beautiful silvery luster of hot-dip aluminized steel sheets. The present invention relates to a treatment method for the purpose of providing corrosion resistance.
一般に溶融アルミめっき鋼板の特徴は銀白色の光沢を有
する美しい表面と優れた耐食性の点とにある。しかし、
この耐食性は高塩分水が結露する様な環境下やNo、イ
オンなどが蓄積して行く自動車マフラー材の底部などに
おいては必ずしも満足すべき状態ではない。In general, hot-dip aluminized steel sheets are characterized by a beautiful surface with a silvery white luster and excellent corrosion resistance. but,
This corrosion resistance is not necessarily satisfactory in environments where high salt water condenses or at the bottom of automobile muffler materials where No. 3, ions, etc. accumulate.
そこで従来からクロム系或はりん酸クロム系のクロメー
ト処理が施されているが、之等の処理条件では前記の様
な苛酷な環境下では充分な耐食性が得られない。特に曲
げ部などの加工部における耐食性に問題が存している。Therefore, chromate treatment using chromium-based or chromium phosphate-based chromate treatment has been conventionally performed, but these treatment conditions do not provide sufficient corrosion resistance under the harsh environment described above. In particular, there are problems with corrosion resistance in processed parts such as bent parts.
そこで通常の処理条件によって得られるクロメート皮I
!Xよりも多量のクロメート皮膜を付与すると耐食性は
良好となるがクロメート皮膜のためその銀白色表面の美
麗さが損なわれ、クロム酸系でおれば黄色系、シん酸ク
ロム系であれば緑色系、の干渉色を呈し銀白色の美しい
表面が損なわれるのみならず光沢も低下する。Therefore, chromate skin I obtained under normal processing conditions
! If a larger amount of chromate film is applied than X, the corrosion resistance will be good, but the beauty of the silvery white surface will be lost due to the chromate film, and if it is based on chromic acid, it will be yellowish, and if it is based on chromium sinate, it will be greenish. , and the beautiful silvery white surface is not only spoiled, but also the gloss is reduced.
またクロメート処理時間も非常に長い時間を要するなど
の問題点がある。Further, there are problems in that the chromate treatment takes a very long time.
そこで先に掲げたアルミめっき鋼板の特徴の一つである
美麗な銀白色を損なう、ことなく、優れた耐食性を有す
る表面処理について検討を行なった。Therefore, we investigated a surface treatment that would provide excellent corrosion resistance without impairing the beautiful silvery white color, which is one of the characteristics of aluminized steel sheets mentioned above.
その結果、クロメート処理を実施した後、有機珪素撥水

無いと、有機珪素撥水剤の塗布ムラが生じ、塗布されな
い部分の腐食を促進することとなるので好ましくない。As a result, it was found that applying and drying an organic silicon water repellent after chromate treatment would serve the purpose. According to the treatment method of the present invention, by performing the chromate treatment, the subsequent application of the organic silicon water repellent can be performed uniformly and without unevenness. The absence of this chromate film is undesirable because uneven coating of the organosilicon water repellent occurs and corrosion of uncoated areas is accelerated.
さらに有機珪素撥水剤にも僅がなから透水透湿性がある
ため、クロメート皮膜がない場合にはアルミが腐食され
、耐食性の点で問題となる。Furthermore, since the organosilicon water repellent also has some degree of water permeability and moisture permeability, if there is no chromate film, the aluminum will corrode, causing a problem in terms of corrosion resistance.

Furthermore, recently, a so-called coating system has become popular as a new pollution-free "no-rinse chromate treatment" that can replace the aforementioned reactive chromate treatment or phosphate treatment for aluminum sheets, cold-rolled sheets, and galvanized steel sheets. Cutting-type adhesive amate treatment, that is, coating-type chromate treatment, also constitutes the present invention, and a typical example of the commercially available treatment agent is H4 (trade name: Acomet C4 (manufactured by Kansai Paint Co., Ltd.)).

You can mention a lot of money. The most important thing in the present invention is to limit the amount of chromium in the chromate film to 5 to 40 M/"; if it is less than 5 gm, the corrosion resistance will be insufficient, especially if the chromium content is The synergistic effect is not particularly noticeable in the left phase.

ある。After forming a chromate film on a hot-dip aluminized steel plate with a thickness of 8 mm and a coating weight of 120 g/W under the conditions shown in Table 1, in the case of chromium phosphate, it is washed with water, but in other cases The material was air-dried or forced-dried with hot air without washing with water, then treated with an organic water repellent to form a film, and air-dried.In order to evaluate corrosion resistance, external appearance was observed with the naked eye, gloss was measured, and A salt spray test (based on J Engineering sz-2371) and a hat bending test were conducted. The main conditions of this test are as follows.

調変化が大となるのは避けられない。Looking at the appearance of the finishing examples of Examples 9 and 9, the present invention was good in all cases, but when the amount of chromium deposited was large as in Comparative Examples Nα6' and 5', the appearance was poor. An example of the change in color tone due to a chromate film is shown in FIG. 1, but in the case of a chromium/chromate film, it is inevitable that the change in color tone will increase as the thickness of the film increases.

上するとは言い難い。When Δb exceeds 8.0 as shown in FIG. 1, the surface exhibits a yellow-green interference color rather than a silvery white color, and the surface cannot be described as beautiful. Furthermore, even if a coating of approximately 20% is applied, it cannot be said that the corrosion resistance of the processed portion is necessarily improved, as can be seen from Comparative Example 6'.

工率が高くなればなる程その変化の程度が顕著となる。Among the comparative examples, those in which the organosilicon water repellent of Nα4/, 2/, 3/, etc. were not saved and applied had poor corrosion resistance in the processed parts. In particular, the higher the processing rate, the more remarkable the degree of change becomes.

さする。Furthermore, as mentioned earlier, even if a romate film is applied in such a large amount that the color tone changes significantly, its contribution to the corrosion resistance of the processed part will not be the same. On the other hand, comparative example N
When an organosilicon water repellent is applied to a test material provided with a chromate film similar to c1', the corrosion resistance of the processed portion is significantly improved. This means that the organosilicon water repellent is not only more resistant to processing than the chromate film, but also easier to process, so there is no localized large load on the surface.
It is judged that this is because the surface stretches uniformly and no local defects are created.

をもたらすことが充分に考えられる。An example of how small the forming load can be during processing is shown in FIG. 2 for reference. In Fig. 2, the horizontal axis represents the stroke, and the vertical axis represents the forming load required at that time.For example, when performing hat bending to a height of 6 degrees, the forming load required for the sample of Example N11. may be 270 Kti, but in the case of the sample of Comparative Example Ni11' which is not coated with an organic silicon water repellent, it requires 900 Kg, which means that a deformable load of appreciable amount is applied to the surface. This suggests that when the organosilicon water repellent is fully coated, there is no local concentration of stress, there are few local defects in the film, and good corrosion resistance is achieved.

どめるべ龜である。Looking at Comparative Example No. 114', even if the same organosilicon water repellent is applied, the synergistic effect will not be significant if the underlying cloide film is small. This means that if the amount of extra cyclomate film is small, there will be areas where no chromate film is applied, and even if an organic film is applied on top of it, the film will be thin and have some moisture permeability, so it will not absorb moisture. It is thought that the chromate film permeates through the aluminum surface little by little and finally reaches the underlying aluminum surface, causing corrosion in areas where there is no chromate film. It is determined from the examples that the lower limit of the chromate film is 5zg/- in terms of the total chromium content. From a practical standpoint, it can be said that it is preferable that the upper limit is less than 50 V- in terms of the total chromium content, but as mentioned above, in consideration of the appearance, it is best to keep it less than 40''g/2.
