The invention discloses a sealing method for an integral tank of an airplane. The sealing method for the integral tank of the airplane is characterized in that during assembly of the wall-plate integral tank, faying surfaces and fillets are sealed through two-component modified polysulfide sealant so as to achieve sealing of assembled gaps, and a detachable covering cap of the oil tank is sealed through low-adhesion modified polysulfide sealant. The sealing method for the integral tank of the airplane has the beneficial effects that the quantity of the needed sealant components is small in the assembling process of the integral tank; the manufacturability is good; the operation is simple, the detachable position of the tank is sealed through the low-adhesion sealant, and the advantage of convenient disassembly and maintenance is achieved. Besides, the tank sealing has the advantages of corrosion prevention, good economical property and high sealing reliability.
