Example Embodiment
[0040] Example 1: A polyethylene nano-antibacterial and light-controllable, biological double-degradable plastic film, which is composed of the following components in parts by weight ratio: 7.88 parts of starch, 0.4 parts of glycerol, 0.1 parts of urea, 0.8 parts of acrylic acid , 2 parts of ferrocene, 1 part of iron stearate, 0.1 part of zinc stearate, 0.3 part of titanate coupling agent, 0.3 part of antioxidant 1010, 87.8 part of linear low density polyethylene, 0.3 part of oxidized polyethylene , Nano TiO 2 10 parts, 0.3 parts of maleic anhydride grafted POE, 0.7 parts of ethylene-vinyl acetate copolymer.
[0041] The preparation method of the photo-biodegradable antibacterial polyethylene film is an extrusion method. The specific production steps of the extrusion method are as follows:
[0042] (1) Take 7.88 grams of starch and bake it at 105°C for 4.5 hours, then react with 0.8 grams of acrylic acid in a high-speed mixer for 0.5 hours, add 0.4 grams of glycerin, 0.1 grams of...
