Paper, improves filter efficiency, reduces windage simultaneously, improves dust containing capacity, increases hydrilla verticillata additive simultaneously, on the one hand can
To improve the filter effect of the harmful gass such as PARA FORMALDEHYDE PRILLS(91,95) further, and further increase the dust containing capacity of the present invention.
Detailed description of the invention
Below in conjunction with detailed description of the invention, it is further elucidated with the present invention.
Embodiment
The preparation method of a kind of hydrilla verticillata enhancement mode air filter paper, comprises the following steps:
Step 1, takes hydrilla verticillata and grinds making beating, is subsequently adding protease and saccharifying enzyme, keeps temperature to be 28-35 DEG C, quiet
Putting 60-72 hour, be then centrifuged separating, rotating speed is 3500r/min, takes off layer precipitate and dries, be ground to 200 mesh with
On, add water and make the solution that concentration is 2%, add dispersant, stir, make hydrilla verticillata additive；
Step 2, is averaged diameter and pulls an oar in the saline solution of 6-8 at the short glass fiber addition pH value of 6-10 μm, add
Entering dispersant, then discongest on fluffer, discongesting revolution is that 10000-15000 turns；
Step 3, adds polyamide polyamine epichlorhydrin resin solution, so in the short glass fiber solution after discongesting
After molding on wet moulding machine, make short glass fiber handsheet, put into drying and moulding in drying machine, baking temperature is
70-90 DEG C, make short glass fiber filter paper；It is short that addition polyamide polyamine epichlorhydrin resin is prevented from two-layer compound tense
Cut glass fiber filter paper surface fracture, during polyamide polyamine epichlorhydrin resin solution mixes with fibrous raw material,
Owing to polyamide polyamine epichlorhydrin resin is cationic, and fibrous raw material is the most in the solution in anionic property, quiet
Under the effect of electro-adsorption, PPE resin can be adsorbed to the surface of fiber during mixing with comparalive ease.Thereafter, exist
In dry run after fiberizing, it is adsorbed between the polyamide polyamine epichlorhydrin molecular resin of fiber surface with poly-
Amide polymeric amine epichlorohydrin molecular resin and the chemical group of fiber surface, as hydroxyl, carboxyl etc. crosslink reaction, formed
The covalent bond of the water resistants such as methylene ether link, makes the combination between fiber have a water resisting property.When filter material runs into water the most again,
Filter material can have certain intensity, without there is frotation and breakage.Described polyamide polyamine epichlorhydrin resin is molten
The concentration of liquid is preferably 0.5-1%.
Step 4, at a coated with adhesive of short glass fiber filter paper, then on binding agent, uniformly coating wheel blade is black
Algae additive, is dried 30-60min at 30-35 DEG C；
Step 5, goes average diameter glass cotton below 2 μm to add pH value and pulls an oar in the acid solution of 5-6, add dispersion
Agent, then discongests on fluffer, and discongesting revolution is that 15000-25000 turns；
Step 6, the glass cotton after discongesting puts into molding on wet moulding machine, and the staple glass after step 4 being processed
Fiber filter paper is placed on forming net, makes glass cotton become in the one side of short glass fiber filter paper coating hydrilla verticillata additive
Type, then 80-100 DEG C of drying, make hydrilla verticillata enhancement mode air filter paper.
The thickness of the short glass fiber layer of described hydrilla verticillata enhancement mode air filter paper and the thickness of glass cotton layer it
Ratio is 1:2-1:1, so can obtain more preferable dust containing capacity and filter efficiency.
