Method.
Background technology
So far with modern social development, oils and organic solvent are gradually increasing the pollution problem of water resource.It is past
Toward after occurring in pollution, people can generally be placed obstacles using oil fence etc., then blocking oil product diffusion uses zeolite, work
Property traditional sorbing material removal seawater such as charcoal, sponge in oil contaminants.But this method have the shortcomings that it is inevitable,
For example, grease adsorbs together, to be difficult to recycle oil product, adsorption ratio low etc..Therefore, exploitation has high oil absorption selectivity, high oil absorption ratio
The new function water-oil separating material of rate becomes the project of an imperative and great challenge.
So far, it is studied in water-oil separating and surely belongs to super-hydrophobic/super-oleophilic functional material with the most of application and earliest.
Super-hydrophobic/super-oleophilic material refers to that the contact angle between material surface and water droplet is more than 150 ° and the contact angle of oil droplet is close
0 ° of material.And it is existing existing water-oil separating material generally uses polymer or inorganic, metal oxide to be made first,
Polymer is easy swelling or dissolving, influences materials'use service life and separating property in oil-based liquid, so, it prepares a kind of
Separation material with excellent separating capacity and effective solvent resistant solubility property is necessary.

Room temperature obtains primary filament slurries；
（2）It is 5% by primary filament slurries pulp washing to concentration of slurry, obtains screen fibre slurries, zytase is added to
In screen fibre slurries, fiber slurry pH to 8.0 is adjusted, is stirred and heating water bath, standing is cooled to room temperature, fibre must be digested
Tie up slurries；
（3）In mass ratio 1:10, by the potassium ferricyanide be added to enzymolysis fiber slurry in, be stirred mixed liquor is placed in
In stainless steel cauldron, after insulation reaction, cooled to room temperature filters to obtain filter cake, dry modified fibre；
（4）In mass ratio 1:5, modified fibre and softwood pulp are stirred and are placed in beater, mashing is handled
Copy paper slurry, is placed in pattern by copy paper slurry and copies and take in device progress copy paper processing, then after paper hot-pressing processing, standing is cooled to
Room temperature obtains filter paper matrix；
（5）In mass ratio 1:10, stearic acid is added in n-hexane, modification liquid is stirred to obtain, filter paper matrix is soaked
In bubble to modification liquid, after immersion treatment, washing, drying, you can be prepared into a kind of resistant to dissolution type oil-water separation filter paper.
Step（1）The boiling is 5~10h of boiling at 0.5~0.8MPa, 160~170 DEG C.
Step（2）The zytase additive amount is 20U/g.
Step（3）Mixing speed is 3200~3300r/min during the insulation reaction.
Step（4）The softwood pulp is the softwood pulp of 15 ° of SR of beating degree.
Step（4）The quantification of 110g/m of the copy paper2。
The beneficial effects of the invention are as follows：
（1）The present invention is that iron ion is loaded to the fiber of enzymolysis processing by raw material by hydro-thermal reaction by the potassium ferricyanide
Surface, after fiber surface enzymolysis processing, zytase destroys the cell wall of pulp fiber surface, in paper pulp fiber of degrading
Hemicellulose so that fiber finer cell wall becomes loose, then under the conditions of high-speed stirred, the uniform wadding warp enzymolysis of iron hydroxide particle
It inside the fibrocyte of processing, is effectively loaded in fibrous inside and surface, so that filter paper material prepared by fiber is had excellent
Different resistance to swelling energy improves dissolubility resistent energy of the filter paper in oil solvent；
（2）The present invention aoxidizes to form iron oxide material by iron hydroxide, uniformly cladding and fiberfill fibers surface, then through low
Surface energy treatments make surface form the cladding coating of hydrophobic structure, are effectively improved the water-oil separating performance of filter paper material,
Simultaneously low-surface-energy processing, coating modification filter paper material surface, make filter paper material solvent resistant oil infiltration and dissolubility resistent significantly
Enhancing.
