Abstract
The invention discloses nano goffered filter paper.The nano goffered filter paper is prepared from, by weight, 30-80 parts of bamboo pulp, 5-40 parts of herba junci setchuensis pulp, 30-80 parts of softwood pulp, 0.2-5 parts of lignin, 1-5 parts of nano-crystalline cellulose, 0.2-0.8 part of a dispersing agent and 0.1-0.3 part of a defoaming agent.All the pulp is treated through an ultrahigh-pressure microjet nano dispersion machine to obtain cellulose nanofibers, and the cellulose nanofibers are harder and lighter than iron and can realize paper sheet light weight when used in the filter paper industry; the added nano-crystalline cellulose can be tightly combined with pulp fibers, and therefore binding force between pulp fibers is increased.
Description
Technical field
The present invention relates to filter paper technical field, be specifically related to a kind of nanometer goffered filter and its preparation method and application.
Background technology
Filter paper has abundant capillary due to it, can inhale the liquid of the quality of load 20%～100% own, and goffered filter is more because of it
Surface is accordion, and the most quantitative filter paper of its surface area ratio has bigger surface area, can retain more solid impurity, with
Time can bear bigger pressure, can be widely used for medicine, chemical products filter, or supporting with deep fried oil filter, be used for eating
Filter with frying oil.
But common goffered filter often uses single fiber to manufacture paper with pulp, and its strainability is difficult to there is room for promotion；It addition, goffered filter
Absorbent properties are poor, service life is short, wet strength is poor, compressive strength is relatively low and papery is uneven to there is filtration, and papery is thick and heavy
Etc. shortcoming.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of filtration, and absorbent properties are good, length in service life, wet strength are good, pressurized
Intensity height and the most even page of papery light-weighted nanometer goffered filter, present invention also offers the preparation side of this nanometer goffered filter
Method.
For realizing goal of the invention, the technical scheme that the present invention takes is:
A kind of nanometer goffered filter, counts by weight, is prepared from the following components:
More preferably, a kind of nanometer goffered filter, count by weight, be prepared from the following components:
As preferably, described dispersant is polyoxyethylene and/or anion-polyacrylamide.
As preferably, described defoamer is selected from one or more of butanol, octanol, silicone oil or pine tar.
As preferably, described bamboo pulp is the bamboo pulp obtained through the screen cloth of 200 mesh.
As preferably, the quantification of 60 ± 10g/ of described nanometer goffered filter, thickness is at least 2.0mm.
Present invention additionally comprises the preparation method of above-mentioned nanometer goffered filter, comprise the steps:
1) by dosage, bamboo pulp, Chinese alpine rush slurry, softwood pulp are added water and carry out being blended in super-voltage micro jet nano-dispersed machine
Carrying out under effect peeling off, tearing between a diameter of 15～100nm, length is at 200nm～the cellulose nano-fibrous slurry of 20 microns
Material, in described slurry, the percentage by weight of containing cellulose nanofiber is 10～30%, preferably 15～25%；
2) being dispersed in water by the nano cellulose crystal of dosage and obtain stable nano cellulose crystal colloid, wherein this is received
The mass fraction of the nano cellulose crystal of rice cellulose crystals colloid is 3～8%, preferably 5～8%；
3) by step 1) the cellulose nano-fibrous slurry of gained, step 2) the nano cellulose crystal colloid, wooden that obtains
Element, dispersant and defoamer carry out making beating in beater and obtain pulping, and the beating consistency of pulping is 3.5-4.5%, beating degree
30-50 ° of SR, the pulping of weight in wet base 6-8g；
4) by step 3) online of the pulping condition routinely that obtains manufactures paper with pulp and squeezes and obtain body paper；
5) with scraper, body paper is carried out wrinkling process；
6) drying obtains goffered filter.
Various slurries are obtained cellulose nano-fibrous by super-voltage micro jet nano-dispersed machine by the present invention, this cellulose Nanowire
Dimension has the characteristic more firmly lighter than iron, can realize page lightweight for filter paper industry.
Bamboo pulp is the paper pulp of moderate fiber length, carefully soft.Sheet pulp bulk, tearability are high, pop strength and tensile strength
Relatively low, there is higher mechanical strength；Chinese alpine rush slurry is clean tough, and fiber is elongated, has superior intertexture power, becomes paper finer and smoother flat
Sliding, mechanical strength is good；Nano cellulose crystal (nano-crystalline cellulose, NCC), its particle diameter is typically 30～100
Between nm, specific surface area is very big, can be dispersed in dicyandiamide solution steadily in the long term and form accurate alternately dispersion, disperse in water
Form stable NCC colloid, nano-cellulose light weight, excellent in mechanical performance, light transmission, its biological degradability and recyclability
Also it is that other reinforcing materials cannot be compared, before NCC has well development as enhancing, retention, filter aid in pulping and paper-making
Scape.
