The present invention discloses an ethylene bis-12-hydroxystearylamine grafted with glycidyl citrate (EBH-g-ECA) and a preparation method thereof. The EBH-g-ECA can be used as a polymer material Functional additives, especially in polyester polymer materials, have both chain extension and crystallization nucleation effects. The invention also provides a heat-resistant polylactic acid continuous extrusion foaming material containing EBH-g-ECA. Using this heat-resistant polylactic acid foaming material can realize continuous foaming technology, and the prepared foamed products have high heat resistance, uniform appearance, low density, and can be completely biodegradable. The present invention also discloses a preparation method of a heat-resistant polylactic acid foam material, which is easy for industrialized production and is of great significance for realizing large-scale replacement of petroleum-based plastic disposable foam products such as PP and PS. |
