Problems solved by technology

[0002] As a building material, wood-plastic flooring has been widely used in outdoor decoration, but its mechanical properties are not high. In order to improve the mechanical properties of outdoor wood-plastic flooring, at this stage the market mostly uses wollastonite, short glass fibers and other materials with a certain length-to-diameter ratio. Fiber, these inorganic fillers can improve the tensile strength and bending strength of wood-plastic flooring, but the dimensional stability of the material decreases significantly, and the product density increases, resulting in heavy weight, which needs to be solved urgently
