Starch-fiber foaming material performance regulation and analysis method based on macro-micro synergistic stress conduction

The invention belongs to the field of fully-degradable foam materials, and relates to a starch-fiber foam material performance regulation and analysis method based on macro-micro synergistic stress conduction, which comprises the following steps: uniformly mixing thermoplastic starch and alkali-treated fibers to obtain composite slurry; carrying out hot-pressing foaming molding on the composite slurry to obtain a starch-fiber foaming material; the mechanical property, the hydrophobic property and the degradation rate of the foaming material are regulated and controlled by changing the fiber length. According to the method, the performance of the starch-fiber foaming material is regulated and controlled by changing the length of adopted fibers, and the starch-fiber foaming material performance change analysis method integrating the rheological property of slurry, the foaming mechanism and stress conduction is provided from the perspective of macroscopic-microscopic synergistic stress conduction.
