Detailed Description
The present invention will be described in detail with reference to the following embodiments.
Example 1
A preparation method of an agricultural film material modified by morph-genetic aluminum oxide is implemented according to the following steps:
and 5, forming the composite film.
The step 1 is implemented according to the following steps: soaking the dried natural scindapsus aureus leaves in NaOH aqueous solution, washing the natural scindapsus aureus leaves with water to be neutral, and drying the leaves to obtain alkali-treated scindapsus aureus leaves.
In the step 1, the concentration of the NaOH aqueous solution is 22 wt%, the soaking time is 27h, the drying temperature is 101 ℃, and the drying time is 2.5 h.
The step 2 is implemented according to the following steps: using Al2(SO4)3Preparation of Al (OH) by dropwise addition of aqueous solution to ammonia water by chemical coprecipitation3Nanometer hydroxide, immersing the alkali-treated scindapsus aureus leaf obtained in the step 1 into the hydroxide aqueous solution in a vacuum-pressure infiltration mode, taking out, drying and repeatedly operating to obtain scindapsus aureus leaf/Al (OH)3A precursor.
Al (OH) in the aqueous hydroxide solution of step 23The mass ratio of the green bonnie leaves treated by alkali to the green bonnie leaves treated by alkali is 94.5: 5.5.
In the step 3, the heat preservation sintering temperature is 900-1200 ℃, the heat preservation sintering time is 1.6h, the annealing temperature is 210 ℃, and the annealing time is 4 h.

The ultraviolet light has obvious absorption effect in the wave band ranges of 2 nm-8 nm and 10 nm-20 nm, but the absorption effect on the wave band above 50nm is weakened.
