| description | The invention discloses a preparation method of lignin modified PBS biodegradable plastic. The method comprises the following steps: 1, carrying out vacuum drying on polybutylene succinate and lignin; 2, adding the dried polybutylene succinate, the dried lignin, a chain extender, an antioxidant, a plasticizer, a lubricant and a heat stabilizer into a high mixer, and fully mixing all above materials; 3, carrying out extruding granulation on the obtained mixture in a double screw extruder; and 4, carrying out film blowing on obtained lignin-PBS composite plastic granules at a certain temperature in order to produce the lignin modified PBS biodegradable plastic. The biodegradable film is produced from the biomass lignin massively existing in the nature and the PBS through the method, and compounding modification meets complete degradation requirements, so the mechanical performances of pure PBS resin are enhanced, the production cost is effectively reduced, and market promotion is facilitated.
