Description
Technical field
The invention discloses a kind of preparation method of hanging raw stock, belong to pulp technology for making paper.
Background technology
With the improvement of people ' s living standards with the enhancing of environmental consciousness, conventional fossil coating for house ornamentation progressively by
Environment-friendly type wallpaper is substituted.To meet wall body decoration requirement, as the body paper of wallpaper basic unit, it is strong that it requires preferable anti-tensile
Degree, dimensional stability, opacity, hydrophobic, deflection and bulk etc..Hanging raw stock requires stability good, most important index
Seek to control the expansion and contraction of body paper, generally require body paper transversal stretching rate no more than 1.5%.And influence hanging raw stock and stretch
The factor of contracting performance is very much：（1）The selection of different slurries：Same pulping process, straw pulp retractility is maximum, softwood pulp
It, hardwood pulp is minimum；And same assortment, kraft pulp retractility are maximum, sulfite pulp takes second place, and mechanical pulp is minimum.（2）Beat
The degree of beating：Production practices prove：Beating degree is higher, and the swollen of fiber, aquation, fibrillating degree are higher, and the paper being copied into stretches
Rate is also bigger.Beating degree, control weight in wet base are reduced, is allowed to not influence formation of sheet, that is, needs to avoid the sub-wire of pulp fiber as far as possible
Brooming, suitably increases fibre cutting, reduces weight in wet base.（3）Manufacture paper with pulp：The transversal stretching rate of page is stretched than longitudinal direction in normal productive process
Shrinkage is big, its main cause has at 2 points：A. fiber from head box online after paper longitudinal arrangement quantity than transversely arranged
It is more, so the linear deformation of fiber is small and transversely deforming is big；B. when page leaves wet end, paper web, which advances, will keep certain
Tension force, hinders the longitudinal contraction of paper web, and cross-direction shrinkage is then bigger, so the transversely deforming of paper is also big.
Solve the problems, such as hanging raw stock stretch it is excessive can first set about from raw material, rational proportion.Bleached chemical thermomechanical pulp
（BCTMP）It is low with production cost, shape, opacity and bulk are high, and page deflection is higher and air permeability is more low excellent
One of point, preferable raw material that can be as production hanging raw stock.Though BCTMP fiber deflections are higher, its fiber is manufactured paper with pulp page
Tensile strength and water-resistance are poor.Above-mentioned deficiency can partly be improved by being properly added masson pine, but the wallpaper produced is former
Paper physical strength is still poor, and the cationic demand of produced plain boiled water is higher.
Therefore, it is bad how to improve mechanical property and the water repelling property of traditional hanging raw stock, stability difference shortcoming, to obtain
The hanging raw stock of more high combination property, is that it is promoted and is applied to broader field, meets that industrial production demand is urgently to be resolved hurrily
The problem of.
The content of the invention
The present invention solves the technical problem of：It is bad for the mechanical property and water repelling property of traditional hanging raw stock,
A kind of the shortcomings that stability is poor, there is provided preparation method of hanging raw stock.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）By needlebush mechanical pulp and leaf wood mechanical pulp in mass ratio 6：1~7：1 mixing, and add needlebush mechanical pulp matter
The bleached chemical softwood pulp of 0.2~0.3 times of amount and the bleached chemical leaf wood of 0.12~0.14 times of needlebush mechanical pulp quality

Acidifying glass fibre is added into mixer successively, biomass coke tar, polyamine epichlorohydrin resin, aluminum sulfate, surface is lived
Property agent and additive, after being stirred, obtain mixture, feed the mixture into beater and be beaten, obtain blank, blank is moved into and is copied
Make in machine and manufacture paper with pulp, dry, obtain hanging raw stock.
Step（3）The protein fibre is soybean fiber, any in milk protein fiber or silkworm protein fiber
It is a kind of.
Step（3）The protease is any one in trypsase or pepsin.
Step（4）The glass fibre is any one in alkali-free glass fibre or medium-alkali glass fibre.
Step（5）The preparation process of the graphite oxide is by the sulfuric acid solution and mass fraction of mass fraction 70~75%
