| titleOfInvention |
Anti-corrosion treatment liquid for welded steel pipe, chemical treatment method of welded steel pipe, molded product of welded steel pipe and welded steel pipe |
| abstract |
An object of the present invention is to provide a rust-preventing treatment liquid for welded steel pipes that can further improve the weather resistance of a chemical conversion treatment film. The above object is an organic resin containing a fluororesin, a compound containing a group 4 element or an ion of a group 4 element, an ester compound of adipic acid or phthalic acid and an alcohol having 1 to 3 carbon atoms, and n- It contains at least one binding accelerator selected from the group consisting of methyl-2-pyrrolidone, and the content of the compound containing the Group 4 element or the ions of the Group 4 element is 0.5 g/L or more in terms of metal atoms. 6 g/L or less, and the sum of the content of the compound containing the group 4 element in terms of metal atoms of the ions of the group 4 element and the content of the bonding accelerator is 20 g/L or less Is achieved. |
