[0028] see figure 1 , the second aspect of the present invention provides a kind of preparation method of fully biodegradable plastic film, comprises the steps:
[0029] S1: Mix PBAT, PLA, thermoplastic starch, chain extender, antioxidant, hydroxyapatite and diisocyanate uniformly with a high-speed mixer to obtain a mixture. Wherein, the stirring speed of the high-speed mixer is 500-1000 r / min, and the stirring time is 5-20 minutes.
[0030] S2: adding the mixture to a twin-screw extruder for kneading and granulation to obtain blow molding material particles. Among them, the twin-screw extruder is preferably parallel to the twin-screw extruder, the temperature of the 1-10 zones of the twin-screw extruder is 145-155°C, the main engine speed is 100-150r / min, and the feeding speed is 1-150°C. 4r / min.
[0031] S3: Add the blow molding material particles to the blow molding machine to blow the film to obtain a fully biodegradable plastic film. Among them, the temperature of the...
