| titleOfInvention | A kind of lignin-modified PPC biodegradable plastic and preparation method thereof |
| abstract | The invention discloses a preparation method of lignin-modified PPC biodegradable plastic, which comprises the following steps: (1) vacuum drying polycarbonate and lignin respectively; (2) adding dried polymer into a high mixer Carbonate, lignin, chain extender, antioxidant, plasticizer, lubricant, and heat stabilizer are thoroughly mixed; (3) the obtained mixture is extruded and granulated by a twin-screw extruder to obtain lignin -PPC composite plastic particles; (4) subjecting the obtained lignin-PPC composite plastic particles to injection molding at a certain temperature to obtain lignin-modified PPC biodegradable plastics. The present invention meets the requirement of complete degradation by introducing biomass material lignin and the lignin-PPC composite plastic obtained by composite modification, and at the same time enhances the mechanical properties of pure PPC resin, effectively reduces the cost of the plastic, and makes It is more conducive to market promotion. |
