Description
Technical field
The invention belongs to pulp technology for making paper, and in particular to a kind of super-strong moisture absorbing paper handkerchief with antibiotic property.
Background technology
Paper is most common article in our daily lifes, no matter reads, reads newspaper or writes, draws a picture, and all obtains and paper connects
It touches.In industry, agricultural and national defense industry production, paper is also be unable to do without.Today, if without paper, that is just not imaginable.
Paper rap off, transmission of culture, develop science and technology and production in terms of, be a kind of strong instrument and material.Review is gone through
History, this important substance are exactly Ancient Times in China working people invention.Papermaking technology and compass, gunpowder, the art of printing are simultaneously known as me
The four inventions of state's Ancient Science and technolog are our peoples to the outstanding contribution made by World Science cultural development.
Paper for daily use is used mainly for people's life daily hygiene, so paper for daily use is usually in paper industry colleague's term,
It is one of paper kind indispensable in people's lives.Its shape has individual square, this to be shawl paper or face tissue,
Have and be rolled into roller barrel shape, it is this to be roll paper.They are usually manufactured by cotton pulp, wood pulp, straw pulp, secondary stock, the measured health of matter
Paper is all made of Original Pulp, its manufacturing process of paper with is similar, and simply requirement is manufactured into very thin extremely brittle weak, so
Purpose be that will rot when running into water, achieve the purpose that environmental protection.
In some cases, people need a kind of paper handkerchief of good water absorption, such as paper for kitchen, absorbent paper towels can be square
Just substantial amounts of bacterium, do harm to huamn body can be grown again while processing absorbs water.
The content of the invention

Hour, be then transferred into reaction kettle, at 170-180 DEG C react 23-26 it is small when, washed after cooling, be obtained by filtration it is heavy
Starch is placed in when drying 5-6 is small in 80-90 DEG C of baking oven up to nano zine oxide；
（3）The nano zine oxide being prepared is added to step according to the ratio that mass fraction is 0.02-0.04%（1）It is anti-
It answers in mixed liquor, adds in OT bleeding agents, sonic oscillation 20-30 minutes under the power of 150-180W, it is 1800- to continue in rotating speed
Disperse 30-40 minutes under 2000 revs/min, be put into baking oven that drying to constant weight under conditions of 80-90 DEG C, by 1450-
1500 DEG C of high-temperature fusions make silk up to the nonmetallic ore fibres.
It is further described as to said program, the paper pulp is broad-leaf forest staple fiber paper pulp.
It is further described as to said program, the wollastonite powder particle size is between 1100-1200 mesh.
It is further described as to said program, step（2）The reaction product washing methods is：By reaction mixture
Using absolute ethyl alcohol supersound washing 2-3 times, deionized water supersound washing 3-4 times is reused.
It is further described as to said program, step（3）The OT bleeding agents addition mass fraction is 0.011-
0.013%。
The present invention has the following advantages compared with prior art：In order to solve the problems, such as that existing water suction paper handkerchief antibiotic property is poor, this
Invention provides a kind of super-strong moisture absorbing paper handkerchief with antibiotic property, and it is 3.5-4.0% that mass fraction is added in process of plant fiber pulp
Nonmetallic ore fibres, which covers zinc oxide of the particle size in 1-10 nanometer ranges, the ore deposit being prepared
Object composite fibre realizes fiber list fasciculation, can with the fabulous combination of plant fiber, using nano zine oxide in mineral fiber surfaces
Micron and nanometer composite structure is built, adhesive attraction of the bacterium on paper handkerchief surface that can inhibit in aqueous solution forms biomembrane, kills
More than 99% bacterium, and with paper product performance is improved improves paper product tensile strength, bursting strength, tearability, opacity, disappears
Except paper electrostatic and reduce paper product shrinking percentage the effects that.
