The present invention relates to a hot dip galvanizing method. INDUSTRIAL APPLICABILITY The present invention is suitable for use in outdoor structures and upholstery materials that require a solid texture and a high-class feel, and can also be used in guard rails, soundproof walls, and the like that dislike strong reflection.

なり、注目を集めている状況である。BACKGROUND OF THE INVENTION In recent years, hot-dip galvanizing has been widely recognized for its high rust prevention ability, and has been widely adopted as a surface coating for outdoor structures and the like. In addition, the surface color and luster unique to hot-dip galvanized products are being utilized more often for interior decoration, which is drawing attention.

が盛んに行なわれている。Although hot-dip galvanizing has been widely used in this way, the surface of hot-dip galvanizing is coated for the purpose of adding harmony with the environment and a sense of quality in outdoor structures. Further, in order to bring out a more luxurious feeling, attempts are being made to attach an embossed pattern such as a satin-finished pattern or a melon pattern instead of the flat surface finish of the hot-dip galvanized material. .

エンボス模様にする技術はいまだ開発されていない。Conventional Technology Originally, the surface of a galvanized product is a smooth surface that directly reflects the surface condition of the steel material to be plated. And, a technique for forming an embossed pattern on the plated surface by only means of hot dip galvanizing has not been developed yet.

をする方法と が実施されてきた。Conventionally, as a means for applying a surface finish of an embossed pattern, for example, blasting a steel material to be plated in advance to make unevenness on the steel surface and then hot dip galvanizing, and when applying surface coating after hot dip galvanizing, After the painting process, a roller press with an embossed pattern is performed, or a special embossing finish such as lightly pressing a base plate with an embossed pattern is performed, and also when applying surface coating after hot dip galvanizing, A method has been implemented in which the surface of a hot-dip galvanized surface is first blasted and then painted.

するという重大な問題が生じた。However, the method of, for example, blasting the steel material to be plated in advance, of course, increases the processing cost, and further, the uneven pattern once formed on the steel base is leveled by the plating layer. However, there was a problem that the original intended pattern was attenuated and it was difficult to reveal it as it was.
The method of performing a special embossing finish after painting was difficult to implement, and the application was restricted, so that it was not possible to reveal a deep embossed pattern. The method of applying surface coating after hot dip galvanizing is to remove the hot dip galvanized layer, which is not recommended in terms of corrosion resistance.If deep engraving occurs in the galvanized layer, corrosion will occur from it. There was a serious problem of rapid progress.

様のめっき面を生成することを基本とする。DETAILED DESCRIPTION OF THE INVENTION The present invention does not require modification of a normal galvanized hot dip galvanizing operation, but by adding 0.01 to 1.0% titanium and 0.001 to 0.1% aluminum to a normal hot dip galvanizing bath,
Basically, it produces an embossed plated surface that cannot be obtained by the conventional hot dip galvanizing bath.

る酸洗い、及び水洗である。The steel material to be plated is first surface-cleaned according to a normal procedure. For example, steps such as degreasing with an alkaline solution, washing with water, washing with mineral acid and washing with water are performed. Examples of preferable conditions are degreasing using a 10 to 15% NaOH solution at a temperature of 60 to 80 ° C., washing with water, pickling with 10 to 15% HCl at room temperature, and washing with water.
ついで、好ましくは、フラクシング工程が実施される。

望ましい。温度は70〜80℃とすることが好ましい。Then, a fluxing step is preferably performed.
As the fluxing agent, any of those conventionally used can be used, but a particularly preferable one is ZnCl 2
-NH is a 4 Cl double salt. If the concentration of the additive element is low, Zn
The Cl 2 : NH 4 Cl ratio is 0.5: 1.5 to 1.5: 0.5, which means that ZnCl 2 is low, but as the additive element concentration increases (Ti concentration is 0.5
% Or more), and ZnCl 2 is preferably increased to, for example, 2: 1 to 4: 1. The temperature is preferably 70-80 ° C.

し支えない。As the raw material zinc for the plating bath, distilled zinc, regenerated zinc or pure zinc can be used (purity 2N to 4N). For example, in the case of one kind of distilled zinc metal (purity 98.5% or more), Pb1.2
% Or less, Cd 0.1% or less, and Fe 0.020% or less. Regardless of which of these is used, there is virtually no change in the embossed pattern or plating finish. Both baths can be lead saturated.

えると、不めっきが発生し易くなる。0.01-1.0% titanium and 0.001-0.1% aluminum are added to the hot-dip galvanizing bath in this invention. If the titanium content is less than 0.01%, no embossed pattern appears. On the other hand, if it exceeds 1.0%, non-plating occurs with general flux. When the aluminum content is less than 0.001%, various colorings may occur on the plated surface, and such coloring may be preferable, but it is not preferable from the basic purpose of obtaining the original color of hot dip galvanization close to silver. Further, when the amount of aluminum is small, a matte pattern is apt to be generated instead of an embossed pattern. When the aluminum content exceeds 0.1%, non-plating is likely to occur.

0.5% or less), 440 to 480 ° C, which is a very ordinary temperature, but it is necessary to shift the bath temperature to a higher temperature as the concentration of the additive element becomes higher, for example, the Ti concentration is 1
About 600%, about 600 ℃ is selected.

材を浸漬することにより実施される。The hot dip galvanizing operation itself is basically the same as the conventional hot dip galvanizing operation in which the material to be plated is immersed in the hot dip galvanizing bath for a predetermined time and then pulled up at a predetermined speed. This is also a feature of the present invention. It is carried out by immersing the material to be plated in a bath of molten zinc containing the required additive material.

The surface can be protected and the appearance can be further improved. A transparent paint is used to express the hue of the plating surface as it is, and a colored paint is used to adjust the shade of the hue. As the paint, synthetic resin paints such as polyurethane, acrylic and epoxy and water-based paints are used, and water-based paints are particularly preferable. Both can be brushed, sprayed and dip coated. Good paint adhesion.

外を問わず幅広い用途への応用が期待される。The effect of the invention is that the surface of the embossed pattern can be obtained only by hot-dip galvanizing, there is no need for preliminary adjustment of the base material, and there is no special coating finishing process. A hot-dip galvanized product with a pattern can be obtained. The surface of the embossed pattern obtained is excellent in beauty, luxury and solid feeling, and does not sacrifice the original corrosion resistance. Therefore, it is suitably used for outdoor structures such as various wall surfaces. It can be used for interior decoration, and even if it is used as it is on the plated surface, a solid texture can be obtained. It is expected to be applied to a wide range of applications both indoors and outdoors.
