The present invention discloses a method for preparing high-strength, high-toughness, biodegradable melt-blown nonwoven materials, comprising the following steps: S1. Premixing: Using poly(lactic acid) chips and poly(butylene succinate) chips as raw materials, premix under specified conditions to produce poly(lactic acid)/poly(butylene succinate) premixed chips; S2. Melt blending: The prepared PLA/PBDO pre-blended pellets are fed into a twin-screw extruder for melting, then extruded through a metering pump and a hanger-type die into a fine melt stream; S3. Hot Melt Forming: The melt undergoes high-temperature, high-speed airflow stretching and shearing to form fibers. These fibers are then collected by a receiving device after self-bonding into a web, yielding poly-lactic acid melt-blown nonwoven materials with diverse morphological structures. This invention'の製造方法は単一のブレンド工程のみを必要とし、追加設備なしでポリ乳酸メルトブロー不織布材料の強度および靭性を向上させる。さらに、本発明はポリ乳酸およびポリブチレンスクシネートを原料として使用し、完全生分解性を達成し、持続可能な発展の要件を満たす。
