| titleOfInvention | Preparation method of modified polylactic acid material with metal effect for 3D printing |
| abstract | The invention relates to a preparation method of a modified polylactic acid material with a metal effect for 3D printing, which comprises the following steps: preparing the following raw materials in parts by weight: 100 parts of polylactic acid, 80-150 parts of metal powder, 1-5 parts of metal pigment, 8-18 parts of a methyl methacrylate shell soft core-shell type core-shell copolymer toughening agent, 0.5-2 parts of a coupling agent, 0.5-1.5 parts of a lubricant, 0.2-0.8 part of a hindered phenol antioxidant and 0.1-0.5 part of a phosphite or thioester antioxidant, wherein the metal powder and the metal pigment are mixed and simultaneously sprayed into a coupling agent solution, the mixture is dried, the modified metal powder, the metal pigment, the polylactic acid, the toughening agent, the lubricant and the antioxidant are mixed and then added into a double-screw extruder for extrusion granulation and drying, the dried granules are added into a single-screw extruder for extrusion, and the wire rod is obtained after hot water, cold water treatment and air drying. The modified polylactic acid material prepared by the invention has the advantages of metal effect, good toughness and difficult degradation. |
