[0032] Example 1:
[0033] The method for preparing a high-airtight antibacterial reinforced film from straws includes the following steps:
[0034] (1) Prepare straw solution:
[0035] Wash and chop the straw (straw straw is straw) into short stalks with a length of 4-6 mm, and crush it by steam explosion (using steam explosion device, or steam explosion device) at a pressure of 1.3 MPa and 80 seconds. Processing to obtain the crushed product;
[0036] Rinse the crushed product with hydrogen peroxide to make it consistent in color and then dry and crush until it can pass through a 60-mesh sieve to obtain straw powder for use;
[0037] Take the ionic liquid and heat it until it is completely melted, add the straw powder and mix, stir at 100°C for 2-3 hours until the solution becomes transparent to obtain the straw liquid; the quality of the straw powder in the straw liquid (ionic liquid straw solution) The percentage concentration is 10%.

[0051] Example 2:
[0052] The method for preparing a high-airtight antibacterial reinforced film from straws includes the following steps:
[0053] (1) Prepare straw solution:
[0054] Wash and chop the wheat straw into short stalks with a length of 4-6 mm. Under the condition of 1.2MPa pressure and 60s, steam explosion (using steam explosion device, or steam explosion equipment) to obtain explosion Product
[0055] Rinse the crushed product with hydrogen peroxide to make it consistent in color and then dry and crush until it can pass through a 60-mesh sieve to obtain straw powder for use;
[0056] Take ionic liquid [1-butyl-3-methylimidazole chloride ([bmim]Cl)] and heat it until it is completely melted, add straw powder to mix, and stir at 100°C for 2-3 hours until the solution becomes transparent. Obtain the straw liquid; the straw powder in the straw liquid (ionic liquid straw solution) has a mass percentage concentration of 8%.

[0062] Example 3:
[0063] The method for preparing a high-airtight antibacterial reinforced film from straws includes the following steps:
[0064] (1) Prepare straw solution:
[0065] The corn stalks are washed and chopped into short stalks with a length of 4-6 mm. The corn stalks are crushed by steam (using a steam explosion device, or steam explosion device) under a pressure of 1.5 MPa and 90 s to obtain the explosion. Product
[0066] Rinse the crushed product with hydrogen peroxide to make it consistent in color and then dry and crush until it can pass through a 60-mesh sieve to obtain straw powder for use;
[0067] Take the ionic liquid and heat it until it is completely melted, add the straw powder and mix, stir at 100°C for 2-3 hours until the solution becomes transparent to obtain the straw liquid; the quality of the straw powder in the straw liquid (ionic liquid straw solution) The percentage concentration is 6%.
