Embodiment 1
[0015] A seaweed polyphenol-inulin-based flame-retardant degradable composite film, its components and parts by weight are: 100 parts of inulin, 15 parts of seaweed polyphenols, 10 parts of red phosphorus, 8 parts of glycerin, and 5 parts of palygorskite clay share.
[0016] A preparation method of a seaweed polyphenol-inulin-based flame-retardant degradable composite film is as follows: (1) dissolving seaweed polyphenols in acetic acid to prepare a seaweed polyphenol solution with a mass concentration of 2%; (2) adding chrysanthemum powder, red phosphorus, palygorskite clay, glycerin, and water, and disperse in an ultrasonic disperser with a power of 600W for 30 minutes; (3) conduct gelatinization at 50°C for 25 minutes, and perform mechanical stirring, and then pour into the mold, Dry at 60°C for 20 hours, peel off the film, and then equilibrate in an environment with a relative humidity of 70% for 36 hours, vulcanize and make tablets with a hot press and a cold press, and f...
