Therefore, there is a demand for a colored hot-dip galvanized material that exhibits an aesthetic color that matches the surrounding environment, rather than the conventional hot-dip galvanized material that has a metallic color. As aesthetic awareness increases, it is expected that colored hot-dip galvanized materials will become increasingly popular in a wide range of fields including architecture, civil engineering, plants, power transmission, transportation, agriculture, fisheries, and more.

離するに至る欠点がある。Prior art and its problems The conventional method for coloring hot-dip galvanized steel is mainly to apply color to the plated steel by painting, but Zn in the plating film of hot-dip galvanized steel is active. As a result, the fatty acids that make up the oil component of the paint gradually decompose with alkaline to form zinc soap. Therefore, there is a drawback that the paint film used for coloring does not adhere to the surface of the plating film and peels off.

No. 7 discloses a coloring method using a hot-dip galvanizing bath to which one or more of titanium, manganese, vanadium, etc. are added. However, it was found that the color tone of the colored hot-dip galvanizing obtained according to the technique disclosed herein was generally very pale, the color quickly faded over time, and the coating was likely to peel off. It was not possible to fully control the color development of the desired color, and the color tone was often too rapid.

: For example, using a hot-dip plating bath of this alloy, it is possible to develop yellow, dark red, and green colors by the following treatments: Yellow: When applied to the steel base material at a bath temperature of 580 to 600°C. Plating is applied, then heated in an atmosphere at a temperature of 500 to 520°C for 20 to 30 seconds, and then cooled with water or hot water or cooling gas.Dark red: on the steel base material at a bath temperature of 580 to 600°C. Plating is applied, and then heated for 30 to 70 seconds in an atmosphere at a temperature of 150 to 520 ° C, and then cooled with water or hot water. Next, this is heated for 50 to 60 seconds in an atmosphere at a temperature of 5oO to 520°C, and then cooled with water cooling, hot water cooling, or cooling gas.The above-mentioned technology is an excellent technology that provides a vivid coloring effect, but it is However, there is a desire to develop a color different from these hues, and furthermore, the relatively long holding time in a heated atmosphere after plating in the above technology has come to be recognized as a disadvantage in continuous operation. There has also been a demand for reductions in energy costs.

Made by I. In the present invention, the zinc ingot used for preparing the zinc alloy must contain impurities Pb1α005% or less. Therefore, JIS H21
It is preferable to use the purest zinc ingot (99995% or more) specified in 07, but if Pb is 0. Special zinc ingots (9999% or more) can be used as long as the OO is regulated to 5% or less. If lead is present in the plating bath (LOO 5% or more), a golden yellow-single blue hue will not develop in a short period of time.

18wt%Mn and Q, 01-(L1wt%T'1) are added.It is known that in order to shorten the holding time in the heated atmosphere after plating, it is better to use a small amount of TI and a relatively large amount of Mnt. is the basis for determining the addition amount range. Therefore, the upper limit of TI is set at f (L 1 wt%. If Tl is less than 101 wt%, the effect of TI addition will not occur and the desired hue will not develop. In order to obtain the desired hue, a large amount of Mn of α2 wt% or more is required, but [if it exceeds 18w4%, it becomes difficult to adjust the hue], and the wetting of the material to be plated with the plating solution deteriorates.

ことによシ実施しうる。Hot-dip galvanizing using this nine-zinc alloy pipe,
The material to be plated is degreased using an alkaline bath, scale removed by pickling, and other operations, and then subjected to 7 lux treatment for plating. For example, flux treatment can be carried out using ZnC12-KF-based solution, ZnCh-NH4
This can be carried out by immersion for a short time in a C1 solution or other known 7 lux solution.

する。After preliminary treatment, the material to be plated is immersed in a plating bath controlled at a specific temperature for t-1 to 3 minutes, then the material to be plated is pulled out of the bath, and by controlling the degree of oxidation of the plating film, a golden color, Violet and blue colors can be obtained freely. Golden, purple, and blue colors develop in the order of increasing the degree of acetylation.

間が雉くてすむ。After the plating material is pulled out of the plating bath, the degree of oxidation can be changed by controlling the cooling rate by changing the cooling method such as atmospheric cooling, water cooling, hot water cooling, forced cooling, slow cooling in the furnace, etc. However, the preferred practice is 450~
The degree of oxidation is controlled by maintaining an atmosphere at a temperature of 550° C. for a predetermined period of time and then changing the cooling rate. Since no color develops when the alloy layer reaches the surface layer, it is important to thicken the oxide film in order to promote the development of the alloy layer. The holding humidity, holding time, or cooling rate are selected so as to bring about proper color development. In the case of the present invention, the heating time can be shortened.

The treatment was carried out by holding in a heated atmosphere of C and cooling. The correspondence between processing conditions and coloring is shown. The golden and purple colors developed in a very short time and the blue color developed in 50 seconds. The 9-plated surface exhibited smoothness and a beautiful appearance color.
表
１ 加熱雰囲気での加熱時間が短いことから連続溶融亜
鉛メツキラインへの適合性を有する。Table 1 The short heating time in a heating atmosphere makes it suitable for continuous hot-dip galvanizing lines.
２ 浴温度が低く且つ加熱時間が短いことからエネルギ
ーコストが削減出来、大量処理に向く。2. Energy costs can be reduced because the bath temperature is low and the heating time is short, making it suitable for large-scale processing.
五 平滑性に富む美感を与え、鮮明な黄金色−紫色一臂
色系列の着色を与える。5. Gives a smooth and beautiful appearance, and gives a vivid golden yellow-purple color series.
