| titleOfInvention | Polylactic acid-ferroferric oxide nano composite foam material and preparation method thereof |
| abstract | The invention discloses a polylactic acid-ferroferric oxide nano composite foaming material, which is prepared by heating the following raw materials in parts by weight: 100 parts of polylactic acid, 1-30 parts of lactic acid graft modified nano ferroferric oxide, 1-10 parts of foaming agent and 0.1-3 parts of accelerant. The invention also discloses a preparation method of the polylactic acid-ferroferric oxide nano composite foaming material, which comprises the steps of taking polylactic acid as a matrix, taking ferroferric oxide nano particles with better microwave absorption characteristics as a microwave absorbent, grafting lactic acid or forming oligomers on the surface of the nano ferroferric oxide to improve the dispersibility of the nano particles in the matrix, preparing the polylactic acid/ferroferric oxide nano composite material by using a melt blending process, and finally heating, foaming and forming by utilizing microwave irradiation to obtain the polylactic acid-ferroferric oxide nano composite foaming material which simultaneously has good foaming effect and mechanical property. |
