The invention provides an aluminum profile anode oxide film nickel-free hole sealing agent and a preparation method thereof, and relates to the technical field of aluminum profile anode oxide film nickel-free hole sealing agents. The invention discloses a nickel-free hole sealing agent for an aluminum profile anode oxide film. The corrosion and scale inhibitor comprises the following raw materials in parts by weight: 10-50 parts of a zinc salt compound, 10-80 parts of a lithium salt compound, 20-50 parts of a calcium salt compound, 8-15 parts of magnesium acetate, 3-8 parts of ammonium acetate, 5-10 parts of sodium acetate, 3-8 parts of a PH stabilizer, 40-80 parts of a surfactant, 60-100 parts of a corrosion inhibitor, 10-50 parts of a scale inhibitor, 5-10 parts of a complexing agent, 2-6 parts of a hole sealing accelerant, 4-10 parts of a stabilizer and 5-15 parts of an ash inhibiting brightener. And 500 to 800 parts of deionized water. The hole sealing agent is low in working temperature, wide in pH value
