More Information
Summary:The invention discloses a nylon blended polypropylene powder for selective laser sintering. The basic formula involves the following components by weight: 70-90% of nylon, 1%-20% of polypropylene, 2-4% of maleic anhydride grafted polypropylene, 0.2-0.4% of a composite antioxidant, and 5-10% of a heat conduction material. The preparation method provided by the invention includes: weighing the materials involved in the formula by weight ratio, mixing the materials evenly, sending the mixed materials into a twin-screw extruder loading hopper, carrying out extrusion granulation and milling, then adding the product into anhydrous ethanol to be dissolved into a saturated alcohol solution, then precipitating the precipitate, and carrying out discharge, separation, cleaning, drying, grinding and sieving, thus obtaining the nylon blended polypropylene powder. The nylon blended polypropylene powder prepared by the method provided by the invention has the advantages of regular shape, uniform size, good aging resistance,
