Description of the invention (Background of the invention 1. Field of invention (please read the notes on the back before filling out this page) The present invention relates to a zinc-filled galvanized steel sheet with excellent residual resistance and hue. , Which can be used for household appliances, building materials, automobiles, etc. 2. Relevant technical descriptions. Zinc phosphate-treated steel plates used in automobiles, household appliances, and building materials used to receive zinc phosphate treatment, chromate treatment, and organic coating treatment. Improve the quality of corrosion resistance and coating performance. But in particular, the use of chromate-treated steel plates has been banned in recent years to prevent possible environmental pollution. The demand for treatment is increasing. • Ordering. But when treated with zinc phosphate alone, the resistance to white rust and the resistance to non-uniform condensation condensation are completely inadequate. Usually it is performed in a hexavalent chromium-containing aqueous solution. Sealing chromate treatment "," sealing treatment "or" post-treatment ". From the perspective of environmental protection, zinc phosphate treatment is still inadequate, which requires cost and development. A method for resistance to good white rust and non-uniform condensation condensation without any environmental protection problems. Most cases of galvanized steel treated with zinc phosphate require a uniform white appearance. If a white coating is applied and the color of the underlying film is discolored, then The color tone after coating also becomes darker, which leads to a decrease in commercial value. To cope with this problem, for example, Japanese Patent No. 2,770,860 describes a treatment method using a forming treatment solution containing a specific concentration of zinc ions and magnesium ions. Because this method is Based on the premise of sealing chromate treatment, its corrosion resistance is insufficient. Japanese Patent Laid-Open No. 9-49〇86 describes a forming process by using the fourth and fifth invention descriptions (2) with a specific proportion of nickel ions and magnesium ions. The solution provides a phosphate treatment method with a high degree of whiteness and excellent adhesion. However, according to this method, the remaining resistance is particularly white rust resistance and non-uniform condensation condensation resistance is insufficient, and the whiteness and uniformity are also insufficient. Japanese Patent Publication Nos. 1-312081 and 3-107469 disclose a galvanized steel sheet having a magnesium-containing phosphate film. This method is particularly resistant to corrosion White rust resistance and non-uniform condensation condensation resistance are insufficient. Although this method provides local whiteness, it is insufficient from the viewpoint of uniform color tone. WOOO / 73 53 5 describes a method that contains magnesium and nickel or manganese. Phosphate film formed on it and galvanized steel sheet with excellent corrosion resistance (red rust resistance) and coating performance. When the goal is to obtain a uniform white appearance, excellent white rust resistance and non-uniform condensation condensation resistance This method is not satisfactory. SUMMARY OF THE INVENTION The present invention aims to provide a solution that can solve the aforementioned problems, does not require sealing chromate treatment, and ensures sufficient white rust resistance and non-uniform condensation resistance, with high whiteness. Zinc phosphate-treated galvanized steel sheet with excellent color tone and excellent color tone. The inventor examined the influence of metal components other than zinc phosphate in the zinc phosphate-treated film formed on the galvanized steel sheet, and found that it can be improved when a relatively large amount of magnesium is obtained. White rust resistance, non-uniform condensation resistance, whiteness and hue uniformity, but it is still insufficient when using this method alone. When, in addition to magnesium, a suitable amount of copper alloys whose electrochemical properties are more expensive than zinc are allowed, these elements act like crystal nuclei, and as a result, a compact and uniform film can be formed, which achieves the purpose of the invention. The present invention is mainly directed to a galvanized steel sheet with a zinc phosphate film, wherein the zinc phosphate film contains at least 2% magnesium and 001 to 1% at least-selected from the group consisting of nickel, cobalt, and copper. The group element and the adhesion value of the film are at least 0.7 g / m2. Description of the preferred embodiment There are no special restrictions on the zinc-zinc steel sheet used in the present invention, and pure mirror coating and alloy plating can be used. The plating method is not particularly limited, and electroplating, hot-dip bell coating, vacuum deposition, etc. may be used. The zinc phosphate thin film formed on the zinc plating layer, magnesium and elements selected from the group consisting of nickel, cobalt, and copper must coexist as metal components other than zinc. The content of magnesium is at least 2%, and the content of at least one element selected from the group consisting of nickel, copper and copper must be 0.01 to 1%. When the content of any one of these components is lower than the individual lower limit, the white rust resistance and the non-uniform condensation resistance are inferior, and the uniformity of color tone is reduced. When these elements co-exist, it becomes a dense and uniform white film with fewer pits. The upper limit of at least one element selected from the group consisting of nickel, cobalt, and copper is set to 1%, because when the content exceeds the upper limit of 1%, the color tone becomes darker and the color tone uniformity decreases. The adhesion value of zinc phosphate film is at least 0.7 g square. When the content is lower than this value, the white rust resistance and the non-uniform condensation resistance are reduced. According to the zinc phosphate-type galvanized steel sheet of the present invention, after the zinc phosphate treatment, heat-sealing chromate treatment is required. From the viewpoint of corrosion resistance, it is of course preferable to use a chromium-free sealing treatment, but it is not necessary. The zinc phosphate film of the present invention can be added to the treatment bath by adding magnesium, nickel, cobalt, copper and other ions in the form of nitrates to the treatment bath, for example, by spraying or ordinary phosphate, zinc or nitrate ions and fluoride-containing compounds. Formed by dip plating in a zinc phosphate treatment bath.丨 .8 Maifu scale Shicai Guanjia County (®S) M specifications ⑵㈣ gallbladder) 593754 A7 ~ --- —__ B7_ V.
