Description

Technical field [0001] The application of the present invention relates to a plastic-wood composite material, especially a micro-foamed high-density polyethylene (HDPE) plastic-wood composite material and a preparation method thereof, and belongs to the technical field of new materials. Background technique [0002] Wood-plastic composite materials, also known as wood-plastic composite materials (WPC), are a new type of material that has attracted more and more attention. It includes a wide range of composite materials. These materials are made of pure Or recycled plastics and natural fiber fillers, the plastics can be high-density polyethylene (HDPE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC) and other materials, and Natural fibers can include wood flour and linen fibers. [0003] Wood-plastic composite materials and their products have the dual characteristics of wood and plastic. They have a strong sense of wood and can be produced in different colors accor...
