の出現が望まれている。By the way, in the case of performing a surface treatment on a large-sized metal-treating material which does not enter the pickling tank, it is necessary to apply a metal surface-treating agent to the surface thereof. When applying, it is required to use a metal surface treatment agent containing no active acid from the viewpoint of odor and safety. However, the metal surface treatment agent proposed in Japanese Patent Application No. 2-238295 has a low viscosity because it does not contain a fluorine compound and is difficult to apply to the metal surface. It contains nitric acid, which causes an odor problem. It is difficult to say that the above problems have been completely eliminated, and further improvement, that is, the advent of a coating type metal surface treatment agent that solves problems such as odor and safety is desired.

た。The present inventor has examined various components and compounding ratios of compounds other than poisonous substances and deleterious substances in order to realize an optimum coating type metal surface treating agent, and as a result, the components shown in Table 1 below. It was found that a coating type metal surface treating agent having good performance can be obtained by blending with the above-mentioned composition ratio.

する。Here, the reasons for limiting the compounding ratio of the components shown in Table 1 will be described. As the fluorine compound, potassium acid fluoride, sodium acid fluoride, and sodium fluoride are effective. If the compounding ratio is less than 1%, the scale removing effect is not obtained, and if it exceeds 30%, the skin becomes rough, that is, per-pickling. Therefore, the compounding ratio of the fluorine compound is set in the range of 1 to 30%. As nitrates, ferric nitrate and ammonium nitrate are effective. If the blending ratio is less than 5%, uneven cleaning may occur.
If it exceeds%, not only the detergency is not improved but also the dissolution of other components is hindered. Therefore, the blending ratio of nitrate is 5 to
The range is 50%. Sulfamic acid, sulfamic acid salts, lactic acid and glycolic acid are effective as organic acids or salts thereof to be added as pickling aids in addition to these fluorine compounds and nitrates. If it exceeds 10%, corrosion will occur. Therefore, the compounding ratio of the organic acid or its salt is set in the range of 0.1 to 10%. In addition to these, magnesium nitrate or magnesium sulfate known as a viscosity-imparting agent is added.
