Abstract
The invention provides a low-temperature phosphating solution containing carboxymethyl cellulose sodium. The low-temperature phosphating solution is a mixed solution prepared by the following components by weight: 420 to 430g of 80% of phosphoric acid, 120 to 125g of zinc oxide, 5 to 7g of ammonium molybdate, 12 to 13g of citric acid, 100 to 150g of zinc nitrate, 4 to 6g of acetic acid, 1 to 2g of carboxymethyl cellulose sodium, 2.0 to 2.5g of chromic acid and water for the rest. The low-temperature phosphating solution is an energy-saving phosphating solution with excellent performance and has the advantages of stable performance, high film forming speed, strong paint film bonding force and good corrosion resistance while in use. The low-temperature phosphating solution is suitable for coating pretreatment of various types of steel iron products such as manufacturing of automobiles, home appliances, agricultural machines and the like so as to enhance the corrosion resistance and increasing the paint film bonding force of the steel iron products in a spraying or soaking way.
