Abstract
It discloses a lignin enhanced wood-plastic composite, belonging to the field of polymer based composites. The wood-plastic composite is composed of one or more of plant fiber, lignin, a recycled thermoplastic plastic, mineral powder and a processing aid, and is processed by a screw granulating extrusion process. Compared with the prior art, the mechanical properties, heat stability and aging resistance of a wood-plastic material are improved by adding lignin into the wood-plastic material according to the present invention.
