Embodiment
A kind of preparation method of water peanut enhancement mode air filter paper, comprises the following steps：
Step 1, water intaking Semen arachidis hypogaeae grinds making beating, is subsequently adding protease and saccharifying enzyme, and keeping temperature is 28-35 DEG C, standing
60-72 hour, is then centrifuged, and rotating speed is 3500r/min, takes lower sediment thing to dry, is ground to more than 200 mesh,
Add water and make the solution that concentration is 2%, add dispersant, stir, make water peanut additive；
Step 2, take average diameter 6-10 μm short glass fiber add pH value pull an oar in the saline solution of 6-8, plus
Enter dispersant, then discongested on fluffer, discongest revolution and turn for 10000-15000；
Step 3, adds polyamide polyamine epichlorhydrin resin solution, so in the short glass fiber solution to after discongest
Molding on wet moulding machine afterwards, makes short glass fiber handsheet, puts into drying and moulding in drying machine, and baking temperature is
70-90 DEG C, make short glass fiber filter paper；Polyamide polyamine epichlorhydrin resin is added to be prevented from two-layer compound tense short
Cut glass fiber filter paper surface fracture, during polyamide polyamine epichlorhydrin resin solution is mixed with fibrous raw material,
Because polyamide polyamine epichlorhydrin resin is in cationic, and fibrous raw material is in often anionic property in the solution, quiet
