Abstract:
     This invention discloses a method for manufacturing profile from waste plant straws. The profile is composed of: powder of waste plant straws 30-50 wt.%, plastic resin 20-40 wt.%, calcium carbonate 15-25 wt.%, flame retardant 3-7 wt.%, anti-aging agent 2-5 wt.%, and silicone oil 1-3 wt.%. The method comprises: (1) fracturing waste plant straws, drying to a water content of 6-10%, and pulverizing to 50-200 mesh; (2) homogeneously mixing the raw materials, extruding in a twin-screw extruder at 150-180 deg.C, and cooling. The profile has such advantages as low cost, abundant raw materials, simple manufacturing process, high compactness, good mechanical properties, good noise absorption, good heat resistance, good flame retardance, good corrosion resistance, high anti-aging capacity and good processability.
