A kind of environmentally acceptable water-based anti-rust agent containing silicate as the major component was prepared by complexing with various anti-rust auxiliaries.The performance of resultant rust inhibitor was evaluated based on observation of appearance,immersion test in NaCl solution,humid test,measurement of Tafel polarization curve and observation of scanning electron microscopy,and the auxiliaries possessing synergistic anti-rust function with silicate were selected.Orthogonal tests were carrie...
