Abstract
The invention discloses a preparation method and application of an amphoteric packing. The preparation method of the amphoteric packing comprises the following steps: adding a packing modifier to an initial packing, and fully stirring to obtain a modified packing; adding strong negative soapstone to the modified packing, and fully stirring to obtain a composite packing; and adding a packing fixation agent to the composite packing, fully stirring and mixing evenly to obtain the amphoteric packing. In the manner, the retention rate of the packing in a pulp fiber can be increased under the premise of not increasing the papermaking cost; and the paper finishing quality is improved.
Description
Technical field
The present invention relates to field of papermaking, more particularly to a kind of preparation method and applications of both sexes filler.
Background technology
In field of papermaking, with the popularization of neutual-alkaline papermaking, to reduce production cost and improving paper physical property
Purpose, it will usually select the modes of many addition Calcium Carbonate.Carbonic acid calcium source is mainly by grinding calcium carbonate (GCC) and precipitation carbonic acid
Two kinds of calcium (PCC) composition, because PCC interweaves the gap to be formed in green end pulp fiber with compared with high length-diameter ratio, keeping beneficial to which.
As the continuous improvement of paper machine speed, green end evacuation moment displacement are increased, certainly will cause originally to keep in pulp fiber sky
Filler at gap is lost in what machine water in a large number, thus, easily causing, production cost substantially rises and paper machine operation is difficult.This
When, retention of the filler in pulp fiber is lifted according to the traditional approachs such as retention agent are increased, easily cause paper intertexture and become
Difference, forms larger negative effect to paper quality.
The content of the invention
The invention mainly solves the technical problem of a kind of preparation method and applications of both sexes filler are provided, by the both sexes
Applying filler on the premise of papermaking cost is not increased can be lifted retention of the filler in pulp fiber, carries in papermaking
Height is into paper product matter.
To solve above-mentioned technical problem, one aspect of the present invention is：A kind of preparation of both sexes filler is provided
Method, methods described include：Filling modifier is added toward initial fillers and is sufficiently stirred for, obtain modified filler；Change toward described
Property filler in add and reinforcing YIN-essence Talcum be sufficiently stirred for, obtain compounded mix；Filler sticking agent is added toward the compounded mix,
It is thoroughly mixed.
Wherein, the addition of described filler modifying agent is 100-150kg/ ton initial fillers；The reinforcing YIN-essence Talcum plus
Enter amount for 200-300kg/ ton initial fillers；The addition of described filler sticking agent is 0.1-1kg/ ton initial fillers.
Wherein, described filler modifying agent be cationic starch, PAMC or cation guar gum in extremely
Few one kind, described filler sticking agent are at least one of PAMA or acrylamide copolymer.
Wherein, it is described reinforcing YIN-essence Talcum is added toward the modified filler and the step of be sufficiently stirred for before, also include：Will
The concentration dilution of the modified filler to 1 ‰, the surface charge PCD value of the modified filler after controlling to dilute for+1200～+
1400μeq/L。
Wherein, it is described toward the compounded mix add filler sticking agent the step of before, also include：Described being combined is filled out
To 1 ‰, the surface charge PCD value of the compounded mix after controlling to dilute is -20～-30 μ eq/L to the concentration dilution of material.
Wherein, the concentration of the reinforcing YIN-essence Talcum is 10-15%.
Wherein, the mean diameter of the both sexes filler is 15-20 microns.
Wherein, packing pump porch of the described filler modifying agent at filler outlet adds；The reinforcing YIN-essence Talcum
Add in the packing pump porch in filler working tank exit；Packing pump of the described filler sticking agent in filler blending tank exit
Porch adds.
Wherein, the initial fillers are that mean diameter is 2.0-2.5 microns ,+400～+600 μ eq/L of surface charge PCD value
Winnofil；The concentration of the initial fillers is 16-20%.
To solve above-mentioned technical problem, another technical solution used in the present invention is：A kind of above-mentioned preparation method is provided
Application of the both sexes filler for preparing in papermaking.
The invention has the beneficial effects as follows：Traditional greyness of paper lifted the means for adopting be by being lifted in add filler and with
Matching retention agent consumption Synchronous lifting, but mass filler thus can be caused to be lost in machine water, cause plain boiled water dense
Degree is abnormal to be raised；Being substantially improved because of retention agent, interweaves into paper and comprehensive strength also substantially can be deteriorated simultaneously.It is different from existing skill
Art, the present invention be by using filler modified, filler is compound, filler set three-step-march measure, after being modified to filler again with
Talcum is compound forming both sexes compounded mix, then that both sexes compounded mix is carried out set by sticking agent is relatively steady to obtain form
It is fixed, and the larger both sexes filler of average particle diameter size, using its average particle diameter size larger (15～20 μm) and surface charge it is in
The significant advantage of both sexes, can be retained in the gap of paper microstructure well, while between the fiber of paper microstructure
There is certain buttressing effect gap, thus on the premise of being lifted into paper ash point, still with preferably into thickness of paper degree.
