The invention belongs to the technical field of polyvinyl chloride (PVC) plastic additives, and particularly relates to a plastic additive for PVC wood-plastic composite materials. The plastic additive is prepared from modified calcium carbonate and magnesium carbonate powder, ammonium molybdate, carbon nanotubes, nano sodium yttrium fluoride, ferrite nano fibers, perfluoropolyether methacrylate,diacetone acrylamide, an aluminate coupling agent and a lubricant. Compared with the prior art, the plastic additive provided by the invention can enhance the direct interface compatibility between the thermoplastic material PVC and the wood fiber material; the plastic additive has an oil absorbing function, and thus, is capable of lowering the PVC melt viscosity, improving the processing flowability and enhancing the comprehensive properties of the obtained PVC wood-plastic composite material. The operational process is simple; and the plastic additive can enhance the compatibility and dispersity of the plastic. Unde
