Sodium, speed of agitator 105-115r/min, mixing time 35-45min are added sulfuric acid and are neutralized to neutrality, polyester is then added
Fat race dicarboxylic acids binary alcohol esters, ethyl acetate, diatomite, polyethylene wax, speed of agitator rise to 155-165r/min, when stirring
Between be 25-35min, obtain mixed liquor A, then mixed liquor A be sent into screw extruder and squeezes out, be granulated, is dry to get compound
Film B；
Mixed at high speed is added in nano-titanium dioxide, nano silver antimicrobials composite silicon dioxide microballoon, degradation accelerator by step 3
It is mixed in machine, mixing speed 1050-1150r/min, mixing time 35-45min obtains coating fluid C；
Coating fluid C prepared by step 3 is coated on composite membrane B surface, is then dried, drying temperature is by step 4
55-65 DEG C, temperature is then risen to 75-85 DEG C by drying time 25-35min, continues to dry 35-45min to get the present invention's
The degradable type preservative film of antibacterial of agricultural product.
8. a kind of preparation method of the degradable type preservative film of the antibacterial of agricultural product according to claim 7, feature exist
In the preparation process is：
Step 1 weighs each component raw material as required；
Rice straw is added in pulverizer and crushes by step 2, and it is 20-60 mesh to be crushed to grain size, and hydroxide is then added
Sodium, speed of agitator 110r/min, mixing time 40min are added sulfuric acid and are neutralized to neutrality, poly- binary aliphatic is then added
Carboxylic acid binary alcohol esters, ethyl acetate, diatomite, polyethylene wax, speed of agitator rise to 160r/min, and mixing time 30min is obtained
To mixed liquor A, then mixed liquor A is sent into screw extruder and squeezes out, be granulated, is dry to get composite membrane B；
Mixed at high speed is added in nano-titanium dioxide, nano silver antimicrobials composite silicon dioxide microballoon, degradation accelerator by step 3
It is mixed in machine, mixing speed 1100r/min, mixing time 40min obtains coating fluid C；
Coating fluid C prepared by step 3 is coated on composite membrane B surface, is then dried, drying temperature 60 by step 4
DEG C, temperature is then risen to 80 DEG C by drying time 30min, continues the antibacterial for drying 40min to get the agricultural product of the present invention
Degradable type preservative film.
