Abstract

The invention discloses a double-layer co-extruded wood-plastic composite plate and a preparation method thereof. A surface and a core layer of the double-layer co-extruded wood-plastic composite plate are prepared from different materials and the core layer is prepared from PE particles selected from urban waste plastic. In production, through a co-extrusion method, the surface completely covers and surrounds the core layer. The core layer does not contact with the external environment. Waste and old plastic impurities of the core layer do not influence appearance and thus only surface functions need to be improved. The preparation method saves a cost and can produce the excellent-performance wood-plastic composite plate with good appearance, flame resistance, weatherability, aging resistance and color stability. Through polishing and galling, a finished product is obtained and has the advantages of environmental friendliness, low cost, wide raw material sources and excellent performances.
