The invention relates to a compound foamed plastic-wood
composite material plate and a preparation method thereof. The preparation method comprises the following steps: adding
polyvinyl chloride and dibasic lead phosphite into a stirring kettle, and evenly mixing at high temperature; adding wood
powder, kaolin
powder, accelerator, azobisformamide,
calcium stearate and
chlorinated polyethylene into the stirring kettle, heating, evenly mixing, and cooling; adding o-toluenesulfonhydrazide and
dibutyl phthalate into the kettle, heating, evenly mixing, cooling, taking out the mixture, and granulating by
extrusion; and after finishing the
granulation, carrying out
extrusion molding on the granules. The invention has the advantages of high manufacturing convenience, low cost, light weight, low
brittleness, excellent
ductility, excellent
shock resistance, favorable surface
tactile sensation, sound insulation, heat insulation,
aging resistance, discoloring resistance and no buckling deformation, is convenient to
mount and maintain, and can adsorb
toxic gas; and the invention consumes less plastic, is environment-friendly and can be recycled. The invention can be used in office buildings, families and other occasions, and can be made into door plates, photo frames, picture frames, skirting plates, suspended pinch plates, suspended beams, pergolas and the like.
