| titleOfInvention | A flame-retardant polylactic acid additive and its preparation method |
| abstract | The invention discloses a flame-retardant polylactic acid additive and a preparation method thereof, comprising the following steps: (1) adding an antioxidant to semi-crystalline PLA particles according to the mass fraction, mixing at a high speed of 70-80°C for 15-30min, Bake at 70-90 o C for 1-3 hours to remove the moisture in the polylactic acid, and store it in a dry environment for later use; (2) Take part of the above-mentioned dried PLA, add initiator, 1-allyl benzotriazole Mix the monomers at 70-80°C for 15-30min at high speed, extrude and granulate to obtain flame-retardant modified PLA particles; (3) according to the mass parts, the remaining dried PLA particles, flame-retardant modified PLA Nitrogen-containing flame retardant powder, toughening agent stearate antioxidant, anti-hydrolysis agent, nano-powder mixed at 70-80°C for 15-30min at high speed, and extruded to obtain a flame-retardant polylactic acid additive . The PLA obtained by the invention has a higher melt flow rate, is suitable for 3D printing, and has better flame retardancy, toughness and strength than ordinary PLA materials. |
