The invention discloses a treatment method for waterproof bamboo products. The method comprises the following steps: hacking bamboo, removing bamboo green, removing tabaxir, drying in the sun to obtain bamboo chips; uniformly mixing ammoniacal copper quaternary and water, adding the bamboo chips, standing in high temperature, performing solid-liquid separation to obtain pre-treated bamboo wood; drying the pre-treated bamboo wood, putting the bamboo wood in a carbide furnace to perform carbonization treatment, filtering, immersing in oil mixture, taking the bamboo wood out, drying, then, coating a pre-treatment varnish on the surface, solidifying, and drying, weaving to obtain a waterproof bamboo product. The pre-treatment varnish is prepared by the following process: adding a cluister beamcompound, lignum cinnamomi camphorae powders, a dispersing agent, and a thickener into a styrene-acrylic emulsion, stirring, reducing stirring speed, adding water, a coalescing agent, acetyl tributylcitrate, 3-iodine-2-propinyl butyl carbamic acid ester, a wetting agent, and an antifoaming agent, stirring uniformly, filtering, to obtain the pre-treatment varnish.
