The invention discloses a method for repairing corrosion defects of a ship body deck. The method is characterized by comprising the following steps: step 1, detecting the ship body deck to be repaired; 2, a cleaning agent is used for cleaning the deck of the ship body; 3, rust spots on the deck are removed; 4, the hull deck obtained after rust removal is treated, and gas is used for purging; fifthly, the deck of the ship body is sealed through a plastic bag, and pressure detection is conducted after sealing is completed; 6, introducing nitrogen into the plastic bag through an inflation valve,and maintaining for 5-6 hours; then deflating through a deflating valve; 7, the plastic bag is removed, and a layer of coating is applied to the deck; eighthly, after the coating in the seventh step is dried, a layer of asphalt is applied to the upper portion of the coating; drying. According to the method, the corrosion site of the deck can be effectively identified, and after being repaired by the method, the corrosion site has effective corrosion resistance in the deep sea, so that the safety of ship running is improved.
