| description | The invention relates to stainless steel rust-removing and anti-rust cream. The stainless steel rust-removing and anti-rust cream is characterized by comprising 20-30 parts of chelating agent, 0-10 parts of polymer, 10-30 parts of corrosion inhibitor, 5-15 parts of friction agent, 1-10 parts of nonionic surfactant, 1-3 parts of xanthan gum, and 10-67 parts of water; modified 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP) serves as the corrosion inhibitor; a preparation method of the modified HEDP comprises the following steps of taking a HEDP solution with the mass concentration of 40%; adding a corresponding amount of a silane coupling agent KH560 according to 25-35 wt% of the mass of the solution, and conducting stirring and reflux reaction under 60-80 DEG C for 1-3 h; and finally, adding triethanolamine, adjusting the pH value to 8-10, and obtaining the modified HEDP.
