The invention relates to the technical field of rust removing solution preparing and particularly discloses an iron material rust removing composite solution and a preparing method thereof. The iron material rust removing composite solution comprises the following raw material components including, by weight, 15-30 parts of phosphoric acid, 3-8 parts of oxalic acid, 3-5 parts of sodium citrate, 3-5 parts of trisodium phosphate, 1-3 parts of urotropin, 4-8 parts of an emulsifying agent and 50-80 parts of water. The emulsifying agent is prepared through the following methods that naked bark oilis adopted as the raw material, maleic anhydride is firstly used for modification, and maleic anhydride modified naked bark oil is obtained; and then the maleic anhydride modified naked bark oil is reacted with lauryl alcohol, and the emulsifying agent is obtained. The iron material rust removing composite solution has a very good rust preventing effect, meanwhile, a very compact protection film can be formed on the surfa
