Embodiment Construction
[0013] The fully degradable plastic film with a wide temperature range and strong toughness is characterized in that it is made of the following raw materials in parts by weight: polyvinyl alcohol 98, acorn starch 65, rice bran 23, nano silicon dioxide 1.9, Diethyl phthalate 3.7, isopropyl titanate 7, aluminum trichloride 0.2, wheat straw fiber 5, appropriate amount of water.
[0014] The preparation method comprises the following steps:
[0015] (1) Add a proper amount of water to the acorn starch and stir to make a paste, heat and pregelatinize for 10-20 minutes, add aluminum trichloride and diethyl phthalate, stir and mix at a constant temperature for 2-3 hours, filter and dry naturally Obtain modified acorn starch;
[0016] (2) Vacuum-dry the wheat straw fibers at 105°C for 2-4 hours, add isopropyl titanate and nano-silica, stir and grind for 2-3 hours, and dry;
[0017] (3) Put polyvinyl alcohol in a water bath at 80-90°C and keep it warm for 30-40 minutes, add the mate...
