The invention relates to a rapid waterproof treatment method for bamboo wood. According to the rapid waterproof treatment method, fluorine gas is adopted for the first time to directly treat wood; atan inert gas environment, fluorine molecules and high-molecular compounds in wood are reacted, hydrophilic group -C-OH on the surface of wood is converted into C-F, C-HF, C-F2 and a small amount of C-F3, the free energy of the surface of wood is reduced, the contact angle of the treated surface can reach 120 DEG, the hydrophobic and oleophobic effects are achieved, and the mildew-proof and anti-corrosion performance is also obviously improved.
