[0028] The preparation method of antibacterial thermoplastic starch granules: take the required amount of each component in Table 1, and then prepare antibacterial thermoplastic starch granules as follows:
[0029] Starch, polyhexamethylene monoguanidine hydrochloride aqueous solution with a mass concentration of 36% and glycerol are mixed and stirred uniformly to obtain a mixture, and the mixture is kneaded, melted, extruded and granulated to obtain antibacterial thermoplastic starch granules.
[0030] The operating conditions for the preparation of antibacterial thermoplastic starch granules are as follows: the mixture is fed into a twin-screw extruder, and the detailed processing parameters are listed below:
[0031] Equipment: ZSK 18mm MEGAlab laboratory extruder
[0032] Temperature distribution: 85 / 110 / 135 / 155 / 170 / 160 / 150 (°C, from feeding area to die)
[0033] Melt temperature: 160-165°C
[0034] Screw speed: 150-180rpm
