Abstract
The invention relates to a cellulose-reinforced polypropylene resin composite material, a preparation method therefor and use thereof. The cellulose-reinforced polypropylene resin composite material comprises, relative to the total weight of the composite material: 65 wt % to 85 wt % of polypropylene resin; 10 wt % to 20 wt % of a cellulose filler; and 1 wt % to 10 wt % of dyed rayon, wherein the color of the dyed rayon is different from that of the polypropylene resin. The cellulose-reinforced polypropylene resin composite material of the invention is environmentally friendly and simple to process, and has a simple molding process. The article prepared therefrom has excellent physical and chemical properties, uniform matte appearance and two-color effect.
