This invention discloses a polymer antistatic wood-plastic composite flooring, relating to the field of wood-plastic composite flooring, comprising joists and wood-plastic composite panels. At least two joists and wood-plastic composite panels are provided, with the two joists arranged parallel to each other and the two wood-plastic composite panels slidably fitted onto the tops of the two joists. A connecting structure is provided on adjacent sides of the two wood-plastic composite panels. In practical operation, when the wood-plastic composite panels are installed outdoors, rainwater will enter the interior of the moisture-proof ring through the heat dissipation holes during rainy weather and drain out from both ends of the moisture-proof ring, reducing the accumulation and erosion of rainwater on the top of the wood-plastic composite panels, thus improving service life. The addition of multiple sets of heat dissipation holes increases the friction on the top of the wood-plastic composite panels, preventing slippage during rainy weather. Because rainwater drains quickly, it dries rapidly after the rain stops due to wind and temperature variations.
