The invention belongs to the technical field of functional plastic-wood materials, specifically relates to an anti-bending, anti-slip and anti-static type plastic-wood composite material, and further discloses a preparation method thereof. According to the anti-bending, anti-slip and anti-static type plastic-wood composite material disclosed by the invention, high-density polyethylene, wood powder, high-strength and high-modulus polyvinyl alcohol fibers, conductive plastic masterbatches, conductive-state polyaniline, nickel coated carbon fibers, 304 stainless steel fibers, conductive polyformaldehyde plastic, a compatibilizer, and auxiliaries such as a coupling agent, a lubricant, and an ultraviolet absorbent are taken as raw materials, and a product is obtained through extrusion pelleting, molding, and surface brush grinding and coarsen treatment through a wire brush. The plastic-wood composite material provided by the invention integrates outstanding anti-bending, surface anti-slip and anti-static properties, and has significant application value.
