Waterproof anti-corrosion traffic sign noctilucent material and preparation method and application thereof

The invention discloses a waterproof anti-corrosion traffic sign noctilucent material and a preparation method and application thereof. The waterproof anti-corrosion traffic sign noctilucent material is prepared from 30-45 wt% of hydrophobic film-forming agent, 10-20 wt% of rare earth doped alkaline-earth metal aluminate long-lasting phosphor material, 10-15 wt% of organic solvent, 5-15 wt% of gaseous phase nano-silica and the balance organic bentonite anti-settling agent. The waterproof anti-corrosion traffic sign noctilucent material is free of toxicity and radioactivity and stable in chemical performance, can shine automatically and continuously after absorbing all kinds of visible light such as daylight, lamplight and environment stray light, can stop hydrolysis of most of the rare earth doped alkaline-earth metal aluminate long-lasting phosphor material after making contact with water and being corroded so that the rare earth doped alkaline-earth metal aluminate long-lasting phosphor material can shine continuously, and has good waterproofness and corrosion resistance.
