Example Embodiment
[0047] Example 1
[0048] A starch modified PBAT / PLA biodegradable plastic film, according to weight parts, including the following components:
[0049] PBAT, 20 parts of PLA, 20 modified starch, 1 mDi, 0.6 parts of PEG400, mustard amide, an antioxidant 1010 0.5 parts, 2- (2-hydroxy-5-methylphenyl) benzene It was 0.5 parts of triazole and 0.1 ADR4468.
[0050] Preparation method is:
[0051] S1. Preparation of modified starch, specific components are: 100 parts of the water content of 8-10%, 0.5 parts of epoxy soybean oil, 20 glycerol, 10 citric acid, 1 stearic acid, coupling agent KH560 2 0.5 parts of maleic anhydride, 0.5 peroxide peroxide.
[0052] The starch, glycerol and citric acid are proportionally propelled, stirred at normal temperature for 30 min, add stearic acid and coupling agent, stirring at normal temperature for 5 min, then add maleic anhydride and peptide isopropylbenzene, stirring is stirred at normal temperature for 5 min, making it mixed Uniform, prepared st...
