Description
Technical field
The invention belongs to pulp and paper technology fields, and in particular to a kind of reuse paper diaper leftover pieces fiber preparation absorption
Paper；The invention further relates to the preparation methods that the reuse paper diaper leftover pieces fiber prepares adsorption paper.
Background technique
In recent years, as domestic economy maintains sustained and rapid growth, convenient, the baby of improvement, the life of people's living standard
Youngster and the elderly increase the usage amount of paper diaper year by year.During producing paper diaper, more leftover pieces and property can be generated
Waste that can not be up to standard, this some materials is directly discarded will to cause the great wasting of resources, while also cause centainly to environment
Pollution.
With the development of urbanization process, while water resources consumption increases, the pollution of water body becomes increasingly severe, especially
It is the industries bring colored dyes contaminated wastewater such as dyestuff, textile, paper and plastics.To with adsorption materials such as active carbons
Material is that the physical absorption paper of representative comes into being, but the raw material of adsorption paper is all with protophyte fiber or reclaimed waste paper at present
Or mixing synthetic fibers preparation absorption paper, it is had no by the adsorption paper of primary raw material and preparation method of paper diaper leftover pieces fiber
Report.It is primarily due to adulterate super absorbent resin SAP (the Super Absorbent of high level in paper diaper fiber
Polymer), and fiber sheet is as Time of Fluff Slurry, and intensity is very low, has essential distinction with plant fiber material, if reuse and making
Standby adsorption paper, needs to solve that super water absorbent resin obstacle, paper strength are extremely low and the problems such as assign adsorptivity, and technology of preparing is wanted
Ask higher, difficulty larger.And using protophyte fiber as the preparation of the adsorption paper of raw material need persistently to fall trees for production,
It needs to bleach slurry, this will cause energy consumption, chemical cost, will also result in more environmental pollutions；It is with recycled fiber
Raw material prepares adsorption paper there is also certain difficulty, because domestic waste recovery constitution is incomplete, leads to domestic waste paper resource
Deficiency, paper plant's wastepaper as raw material depends on import more, and waste paper requirements for sale is gradually increased in recent years, and imported waste paper is caused also to break
Layer, finally also influences the reuse of waste paper, and waste paper is again with needing by the processes such as deinking, sterilization, complex process；To synthesize fibre
Mixed plant fiber preparation absorption paper is tieed up, there is a problem of that material is difficult to degrade.

In step 5, the concentration of calcium chloride solution is 0.5mol/L.
The reason of each raw material is selected in the present invention is as follows:
(1) the reason of adding aluminium polychloride, bentonite, zeolite powder, cellulose microsphere
Since addition aluminium polychloride can destroy the interfacial electric double layer of SAP gelatinous mass, inside and outside the two of the substance are improved
Phase density is poor, and interior phase is promoted to be easy to be precipitated, and bentonite adsorption promotes the thickness of gel to become larger in SAP gel surface, gel
The ratio between surface area relative gel volume becomes smaller, and with the formation of epidermis, builds up pressure in large quantities inside gel, causes in gel
External pressure difference becomes larger, and gel surface is promoted to be easily broken.The raising of two-phase density contrast, the enhancing of internal and external pressure difference inside and outside gel
Under synergistic effect, finally cause the destructurized of gel, swelling variation becomes irreversible.Make to make SAP lose water suction
With not re-forming gel form.
The crystal structure of zeolite is to be linked to be three-dimensional screen work by silicon (aluminium) oxygen tetrahedron, is had in screen work of all sizes
Hole and channel have very big opening.Cavity of different sizes present in lattice can be drawn and of different sizes lose suction
The SAP particle of water effect, meanwhile, it is given to the certain absorption property of paper.
Cellulose microsphere is porous surface, and the spherical structure (as shown in Figure 1 and Figure 2) of central hollow has suction-operated,
Paper absorption property can be improved into.
(2) using sodium alginate, konjac glucomannan, collagen as sizing agent the reason of
Sizing agent is made of sodium alginate, konjac glucomannan, collagen, environment friendly and pollution-free.Wherein, sodium alginate has fine
Film forming, the substrate as sizing agent；Konjac glucomannan is added later, plays thickening, bonding and stable effect, while can have
Effect improves the toughness of sodium alginate film forming；The strand of collagen is in three-dimensional spiral structure, contains firm peptide bond and crosslinking
Key, makes it have excellent mechanical performance, and collagen and water occur aquation, are swollen after water suction, has colloidal nature, add
Being added to is that can effectively improve the caking property of sizing agent in sizing agent, improves the mechanical performance of adsorption paper.
Paper diaper leftover pieces fiber used in of the invention and embodiment is paper diaper absorbed layer fluff pulp fibers；The present invention is implemented
Chemicals used in example includes the white aluminium polychloride that rich environmental protection company production is moistened in Zhengzhou City；The VF- of Wei Ke company, U.S. production

In beaker, according to wintercherry than the concentrated sulfuric acid that mass concentration is 61% is added for 10ml/g, 2~3min of stirring dissolves pulpboard, so
20min is reacted in the case where temperature is 45 DEG C of water bath condition afterwards, is persistently stirred using blender in reaction process, until reaction
At the end of, stop reaction with deionized water dilution, obtains white uniformity suspension.By this suspension centrifuge centrifugal water
It washes, outwells supernatant liquor every time, retain lower layer's decorating film and continue that water cleaning is added to be centrifuged, after eccentric cleaning 3~4 times, make final obtain
Stop centrifugation when the lotion pH arrived is between 4~5, this white emulsion is put into bag filter (molecular cut off 8000~14000)
In, it is constant to pH value with deionized water dialysis a couple of days.Suspension after dialysis handles 15min with supersonic oscillations, micro- to avoid
Crystalline cellulose is assembled because of overheat, and ultrasonic treatment carries out in 5 DEG C of low temperature water-baths.The microcrystalline cellulose water phase that will be ultrasonically treated
Suspension is dried, using spray dryer, inlet temperature be 160 DEG C under the conditions of by microcrystalline cellulose suspension liquid of aqueous phase
Drying is to get cellulose microsphere.(the same paper of method " influence of the drying means to acid hydrolyzed cellulose pattern and structure ", Shaanxi
