| titleOfInvention | Treatment agent and method for quickly generating rust layer on surface of weathering resistant steel without chloride ions |
| abstract | The invention relates to a treatment agent and a method for quickly generating a rust layer on the surface of weathering resistant steel without chloride ions, wherein the treatment agent consists of an agent A, an agent B and an agent C, and the agent A is hundreds of massThe composition comprises the following raw materials: CuSO 4 0.4 to 2 percent of sodium dodecyl sulfate, 0.005 to 0.02 percent of sodium dodecyl sulfate and the balance of water; the agent B comprises the following raw materials in percentage by mass: EDTA disodium 0.001-0.005%, NH 3 ·H 2 O 0.1％～0.55％、H 2 O 2 4-8 percent of water, and the balance of water; the agent C is a covering agent aqueous solution, and the content of the covering agent is 0.5-2.5% by mass percent. The advantages are that: simple preparation and no organic solvent pollution. The treatment agent does not contain chloride ions, so that the adverse effect on the rust prevention performance caused by the retention of the chloride ions in the rust layer in the treatment agent can be avoided. |
