| titleOfInvention | Method for preparing nylon powder for selective laser sintering based on reversed phase suspension polymerization method |
| abstract | The invention discloses a method for preparing nylon powder for selective laser sintering based on an inverse suspension polymerization method, wherein an oil-soluble medium, a monomer, a dispersant and water are mixed according to the mass part ratio of 30-80: 10-50: 0.1-5: 0.05-2 to prepare a water-in-oil suspension; the water-in-oil type suspension liquid adopts a hydrolytic ring-opening polymerization mechanism and sequentially undergoes a high-pressure polymerization reaction, a normal-pressure bubbling reaction and a negative-pressure polymerization reaction at the temperature of 230-275 ℃; then, carrying out post-treatment on the polymerization product to obtain the nylon powder; the monomer is selected from lactam; omega-aminocarboxylic acids; omega-aminocarboxamides; diamines, dicarboxylic acids, equimolar mixtures of dicarboxylic acids/diamine salts; at least one of omega-aminocarboxylates. The powder material prepared by the invention has the relative viscosity of 1.8-3.2, uniform appearance, narrow particle size distribution, smooth surface, no holes, excellent dispersibility and fluidity and is suitable for forming selective laser sintering materials. |
