Abstract:
    The synthesized stalk profile is prepared with crop stalk powder 40-70 wt%, plastic resin 20-40 wt%, calcium carbonate 5-15 wt%, fire retardant 1-3 wt%, antiager 1-2 wt%, lubricant 1-3 wt% and brightener 1-2 wt%. The preparation process includes the following steps: drying crop stalk to water content of 8-15 wt% and crushing to 100-300 mesh; mixing materials in the said proportion and blending in a blender at 130-170 deg.c for 10-15 min; extruding in a double screw extruder and cooling to form. The present invention has low cost, rich material source and simple preparation process, and the profile has high compactness, excellent mechanical performance and other advantages.
