Close to add in mixer and stirred 1-3 hours under 200-300r/min, add modified active carbon fiber, the day of step 2 preparation
So sterilization extract is sent into baking oven after continuing stirring 2-4 hours and dried at 85-95 DEG C in the air-conditioning invented for 15-25 hours
Machine multifunctional filtering net materials.
7. a kind of preparation method of air-conditioning internal machine multifunctional filtering net materials according to claim 6, it is characterised in that
The preparation process is：
Step one, each component raw material is weighed on request；
Step 2, NACF is first put into the sodium hydroxide solution that concentration is 0.5mol/L and soaked 0.4 hour, with distillation
Water washing 3 times, places into 0.5mol/L dilute nitric acid solution and soaks 0.4 hour, with water washing is distilled 3 times, places into
Soak 0.4 hour, dried 13 hours at 110 DEG C with 3 feeding drying bakers of distillation water washing in 0.5mol/L ethanol solution,
Obtain modified active carbon fiber；
Step 3, epoxy resin, processing aid are mixed and added in mixer, and stirring adds poly- for 2 hours under 250r/min
Isosorbide-5-Nitrae-diphenyl diacetylene, which continues to stir, obtains mixed liquor A in 3 hours；
Step 4, mixed liquor A made from heat conduction additive, the nano titanium dioxide water-dispersion liquid that concentration is 40%, step 3 is mixed
Close to add in mixer and stirred 2 hours under 250r/min, add modified active carbon fiber, the natural disinfection of step 2 preparation
Extract continues feeding baking oven after stirring 3 hours and the air-conditioning internal machine multifunctional filtering invented for 20 hours is dried at 90 DEG C
Net materials.
8. a kind of preparation method of air-conditioning internal machine multifunctional filtering net materials according to claim 6 or 7, its feature exists
In the poly- Isosorbide-5-Nitrae-diphenyl diacetylene preparation method is：A, by weight 1-3 parts of lauryl sodium sulfate of preparation, 0.3mol/
L 2-5 parts of sodium chloride solution, Isosorbide-5-Nitrae -5-7 parts of diphenyl diacetylene monomer, 0.1-0.3 parts of benzoin methyl ether hexamethylene, 1- amylalcohols
0.1-0.3 parts；B, lauryl sodium sulfate addition sodium chloride solution is sufficiently stirred for dissolving and obtains transparent solution, then added
Isosorbide-5-Nitrae-diphenyl diacetylene monomer, benzoin methyl ether hexamethylene are sufficiently stirred for obtaining white emulsion, add the mixing of 1- amylalcohols equal
It is even, irradiation in ultraviolet light is placed under stirring and obtains within 10 hours poly- Isosorbide-5-Nitrae-diphenyl diacetylene.
