The invention belongs to the technical field of palm rattan material processing, and particularly relates to an anti-tarnish treatment method for yellow rattan materials. The method comprises the steps that the yellow rattan materials are obtained by peeling freshly cut yellow rattans, the yellow rattan materials are immersed in an anti-tarnish slurry for achieving slurry hanging, and then the yellow rattan materials can be transported or stored after being placed under the room temperature condition for 20 minutes, wherein the anti-tarnish slurry is prepared from plasticizer modified starch,ethyl 2-aminobenzoate, nano-zinc dioxide, urea, hydroxymethyl cellulose, a curing agent, boric acid, diethylene glycol and water. Compared with the prior art, the anti-tarnish treatment method for theyellow rattan materials has the following advantages that by means of the anti-tarnish slurry, uniform slurry hanging on the surfaces of the yellow rattan materials can be achieved, and the slurry can rapidly cured into films under the room temperature condition, so that anti-tarnish effect on the yellow rattan materials is achieved; meanwhile, the anti-water-absorption effect can be achieved, and the mechanical property of the yellow rattan materials can be prevented from getting poor; and the yellow rattan materials treated through the anti-tarnish treatment method are transported or storedunder normal conditions, and the appearance color and the mechanical property of the yellow rattan materials cannot be affected.
