Description
Technical field
Connect the present invention relates to modified calcium carbonate packing technique field, more particularly to a kind of special cationic chitosan of copy paper
Branch modified calcium carbonate and preparation method thereof.
Background technology
China is a papermaking big country, and copy paper is to require technical indicator paper kind very high in these paper products, in day
Often in work copy paper frequency of use highest, the quality of copy paper will directly affect the speed and text body of operating efficiency
It is attractive in appearance, thus it is the current technical issues that need to address that copy paper all technical how is improved in paper-making process, most often
Method is addition filler.
Calcium carbonate due to cheap, and with nontoxic, tasteless and nonirritant, chemically stable, easily dry, energy consumption is low, color
Damp good (white), the interference to other colors is small, easy coloring, many advantages, such as loading is big, is filled with papermaking fitting
The trend for answering neutual-alkaline papermaking to develop, it is few to coating binder requirement, it is to apply more at present also with preferable rheological characteristic
One of filler added in paper, Activities of Some Plants fiber can not only be substituted, the rate of water loss and paper for improving paper stock are dried
Speed, saves energy consumption for drying, so as to reduce production cost, but also with many other advantages, such as improves paper optical property,
Increase paper smoothness, improve paper printing characteristic etc..However, with the increase of calcium carbonate addition in paper, what is be filled with is negative
Effect is also gradually displayed, such as in the strength character decline of paper, sizing efficiency variation, the wire-cloth lost of life, printing easily
There is hair and powder dropping phenomenon etc..These defects for causing are filled with order to overcome or alleviated by paper, so that being carried out to calcium carbonate
Improvement and functional modification, the research being modified to its surface are more active, and starch has preferable film forming and can improve paper
It is the reason for Zhang Qiangdu, and wide material sources, cheap, it is preferable filler covering material.Therefore, document《Starch conversion carbonic acid
Calcium filler improves the research of copy paper performance》Gelatinization is carried out after being blended with starch and pearl filler swelling, then be dried and
Milled processed is prepared for starch coating modification pearl filler and is applied in copy paper production.Result of study shows：Form sediment
Pearl filler after powder coating modification possesses stronger anti-shear performance, while having retention higher；Addition starch bag
The paper strength performance for covering modified calcium carbonate is higher, and the amplitude that strength character declines substantially slows down.
But it is calcium carbonate modified more single in document, and calcium carbonate granule adsorption one layer of calcium ion, in weak base
Property, Antacid effectiveness is poor, can be only applied to the filler of neutral or meta-alkalescence papermaking, its range of application is limited, secondly because carbon
The effect of sour calcium surface hydroxyl, makes its surface hydrophilic oleophobic, is unfavorable for dispersed in non-polar system, is filled with making
Obtained copy paper water proofing property is poor in paper, printing performance is poor, and easily hair and powder dropping phenomenon occurs in paper printing, so that changing
Enter existing production technology and recipe ratio row, with the continuous maturation of the technical research of nano material, be applied to papermaking filler
Developing a kind of copy paper Mobyneb modified nano calcium carbonate with functions such as acidproof, waterproofs can make up prior art
Deficiency.
The content of the invention
The object of the invention is exactly to make up the defect of prior art, there is provided a kind of special cationic chitosan of copy paper connects
Branch modified calcium carbonate and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of special cationic chitosan graft modification calcium carbonate of copy paper, is made from the following raw materials in parts by weight：Calcium carbonate 94-
96th, wheaten starch 15-18, cationic chitosan 6-8, succinic anhydride 2.3-2.6, polypropylene fibre 3-4, ginkgoic acid 1.5-1.8,
Calcium stearate 0.4-0.7, magnesium chloride 0.2-0.4, sepiolite powder 7-9, tetraethoxysilane 5.6-5.9, cinnamon oil 3-5, octyl group
Phenol polyethenoxy ether 1-2, nano zine oxide 2.2-2.6, appropriate deionized water.
A kind of preparation method of the special cationic chitosan graft modification calcium carbonate of described copy paper, including following step
Suddenly：
（1）Sepiolite powder is added into mass fraction to be impregnated 10-12 hours in the magnesium chloride solution of 2-4%, filtration washing to neutrality
Ginkgoic acid, OPEO is added to grind 20-30 minutes to obtain modified meerschaum powder；
（2）Wheaten starch, nano zine oxide are stirred and evenly mixed, tetraethoxysilane, polypropylene fibre ultrasonic grinding 30-40 is added
Minute, it is spray-dried to obtain modified wheat starch；
（3）By step（2）Obtained modified wheat starch deionized water is configured to the suspension that concentration is 3%, adds carbonic acid
Calcium, succinic anhydride, step（1）Material stirring is mixed, and is placed in 90-100 DEG C of water-bath and is reacted while stirring 2-3 hours until condensing
Into bulk；
（4）The above-mentioned material for condensing into bulk is smashed to pieces drying, adds cationic chitosan, cinnamon oil and other residual components to use
Ball mill grinding is to particle diameter between 600-800 mesh, drying discharges.
It is an advantage of the invention that：The present invention is first by wheaten starch after silane coupler modified then common with pearl filler
Gelatinization is carried out after mixed swelling, finally add cationic chitosan and the treatment of other active ingredient mill-dryings, make pearl filler
The particle diameter increase of particle, on the one hand increases the distance between calcium carbonate microparticle, reduces intermolecular interaction, can improve carbon
The agglomeration of sour calcium particle, on the other hand can avoid the directly contact of pearl filler and paper pulp fiber, and become starch
Contact of the gel with paper pulp fiber, forms hydrogen bond connection, increased the adhesion between calcium carbonate filler particles and paper pulp fiber,
The fall of filled paper strength character is slow down, obtained modified calcium carbonate surface is smooth, hydrophobic oleophilic oil, whiteness are good, shearing resistance
Cut that performance is strong, retention is high, being applied to duplicate paper wadding, can to improve the oil absorbency of copy paper, anti-microbial property, surface strong
Degree, deflection and smoothness.
