Abstract

The invention discloses a rust removal phosphating solution which comprises following components: 50-55 parts of phosphoric acid, 40-45 parts of formic acid, 30-35 parts of hydrochloric acid, 5-10 parts of salicylic acid, 3-8 parts of acetic acid, 5-10 parts of ethyl alcohol, 1-3 parts of glutamine, 10-15 parts of maleamic acid, 5-8 parts of nictinamide, 3-5 parts of sodium hydroxide, 5-6 parts of sodium phosphate, 3-8 parts of sodium pyrosulfite, 6-10 parts of sodium pyrophosphate, 6-10 parts of lauryl sodium sulfate, 3-5 parts of methyl alkenyl polyoxyethylene ether, 10-15 parts of cyclohexane, 5-8 parts of paraxylene and 2-5 parts of phenol. The rust removal phosphating solution simplifies the acid pickling process, lowers heavy labor, realizes acid pickling and phosphorization in one step, cannot cause combustion or explosion, has no pungent smell, contains no harmful ions like zinc, chromium and manganese, does not pollute the environment, does no generate waste liquor, does not affect the performance of metal materials, and has good rust removal effect; and the phosphate film does not damage the skin of paint.

Description

technical field [0001] The invention relates to the technical field of a metal surface treatment solution, in particular to a rust removal and phosphating solution suitable for surface treatment of steel components. Background technique [0002] At present, the rust removal and phosphating solution for metal surface treatment is prepared by adding betaine, glycine or quaternary ammonium surfactant and oxo-salt oxidizing agent to the aqueous solution of inorganic acid or organic acid. And the acid that adopts is phosphoric acid, sulfuric acid, hydrochloric acid, citric acid, glycolic acid and acetic acid etc., adopts surface activity to be lauryl betaine, hard betaine etc., the oxo salt oxidant tetrahydroperoxide that adopts etc. Although the treatment solution of this type of formula can remove rust and prevent rust, it consumes a lot of various surfactants, has high cost, and is toxic. Contents of the invention [0003] The purpose of the present invention is to provide ...
