This invention discloses a high melt strength PLA composite material and its preparation method.
The high melt strength PLA composite material comprises the following components: PLA, carboxyl-terminated nitrile rubber, bis-aminopropyl polydimethylsiloxane, whiskers, antioxidants, lubricants, and accelerators.
During preparation, the components are put into a twin-screw extruder according to the ratio and extruded to obtain high melt strength PLA composite material particles.
This invention improves the melt strength of the material by extending the PLA molecular chain and introducing whiskers, allowing for the production of degradable products with good appearance and physical properties through processes such as blow molding, injection molding, and extrusion.
