manufacture example 1
[0106] Manufacturing example 1 (Manufacture of metal surface treatment composition)
[0107] Put 100 parts by mass of deionized water into the container, add 30 parts by mass of 30% hydrogen peroxide aqueous solution and fully stir to obtain a solution with a liquid temperature of 25°C, add 15 parts by mass of vanadium to the above solution ammonium acid, and stirred for 30 minutes, thus obtaining an aqueous perovanadic acid solution.
Embodiment 1~9 and comparative example 1~2
[0109] Each composition for metal surface treatment was produced according to the composition shown in following Table 1, 2. In addition, the compounding quantity of each raw material in Table 1, 2 is shown by the solid content mass ratio in the metal surface treatment composition which is an aqueous liquid.
[0110] Using deionized water, a metal surface treatment composition was prepared so that the solid content was 15%.
[0111] in FIG. 1,( * 1)~( * 4) The raw materials are the following compounds.
