Abstract
The invention discloses a kind of preparation method of papermaking special calcium carbonate filler, first calcium hydroxide and starch are blended in water, then carbon dioxide in-situ preparation calcium carbonate is passed through into solution, so as to obtain calcium carbonate starch Inorganic-organic Hybrid Material, last graft acrylamide obtains papermaking special calcium carbonate filler.The preparation method of the present invention, which first passes through calcium carbonate and starch being combined, obtains Inorganic-organic Hybrid Material, then with acrylamide to its further graft modification, the binding ability and the retention in paper of filler and paper fibre can effectively be lifted, the intensity and surface property of paper can be improved again, with higher practical value.
Description
Technical field
The present invention relates to pulp technology for making paper, more particularly to a kind of preparation method of papermaking special calcium carbonate filler.
Background technology
Calcium carbonate is conventional papermaking filler, and calcium carbonate is added in paper production, can not only improve paper whiteness,
The performances such as smoothness, printing adaptability, moreover it is possible to reduce fiber consumption, reduce papermaking cost.To reach above-mentioned purpose, in papermaking
Always it is to try to increase the consumption of calcium carbonate in journey.Paper and paper-making process are also adversely affected however, being filled with calcium carbonate, example
Such as, interfibrous adhesion can be destroyed in the forming process of page by being filled with calcium carbonate, cause the intensity of paper to decline, easy during printing
Hair and powder dropping, can also reduce the toughness of paper and absorb the ability of ink.Meanwhile, the adhesion of calcium carbonate and fiber is weak so that
Retention of the filler in page is low, is lost in seriously, raw material availability is low, also increases wastewater treatment capacity and processing cost.
CN106368056 is but this straight by the way that the method for calcium carbonate and starch blending to be improved to the retention and physical property of filler
Connect binding ability lifting of the method for mixing to calcium carbonate and paper limited, it is necessary to make improvements.
The content of the invention
The object of the invention is exactly that there is provided the papermaking that a kind of retention is high, loading is big in order to make up the defect of prior art
The preparation method of special calcium carbonate filler.
The present invention is achieved by the following technical solutions：
A kind of preparation method of papermaking special calcium carbonate filler, comprises the following steps：
（1）20-30 parts by weight calcium hydroxide, 5-10 weight starch and 0.5-1 parts by weight sodium tripolyphosphate are added jointly
Be sufficiently mixed in 100-150 parts by weight water it is uniform, be then passed through under agitation carbon dioxide to slurry pH be 6.5-7.5,
Obtain calcium carbonate-starch complex sol；
（2）3-5 parts by weight propylene acid amides and 0.5-1 parts by weight Tween-80 are added into 100-150 parts by weight steps（1）
To calcium carbonate-starch complex sol in be well mixed and pH is adjusted to 7-8, then add 0.1-0.15 parts by weight initiators,
In 70-80 DEG C of stirring reaction 2-4h under nitrogen protective condition, cool down, filter, dry and grind uniform, obtain the special carbon of papermaking
Sour calcium filler.
The step（1）In speed of agitator be 1000-1500r/min.
The step（1）In whipping temp be 30-60 DEG C.
The initiator is potassium peroxydisulfate.
One or more of the starch in cornstarch, tapioca and farina.
It is an advantage of the invention that：
First calcium hydroxide and starch are blended in water by the present invention, and carbon dioxide in-situ preparation carbonic acid is then passed through into solution
Calcium, so as to obtain calcium carbonate-starch Inorganic-Organic Hybrid Material, last graft acrylamide obtains papermaking calcium carbonate for special use and filled out
Material.The preparation method of the present invention, which first passes through calcium carbonate and starch being combined, obtains Inorganic-Organic Hybrid Material, the hydroxyl energy of starch
With paper fibre formation hydrogen bond, the binding ability with paper fibre, Ran Houyong can be lifted with fiber formation bridge formation network structure
Acrylamide to its further graft modification, the amide group of acrylamide can with paper fibre formation hydrogen bond, have concurrently lifting with
The binding ability of paper fibre and the effect of increase paper strength, preparation method of the invention can effectively lift filler and paper
The binding ability of fiber and the retention in paper, can improve the intensity and surface property of paper, with higher practicality again
Value.
Embodiment
A kind of preparation method of papermaking special calcium carbonate filler, comprises the following steps：
（1）20kg calcium hydroxides, 5kg starch and 0.5kg sodium tripolyphosphates are added jointly and are sufficiently mixed in 100kg water uniformly,
Then it is 6.5 to be passed through carbon dioxide under agitation to slurry pH, obtains calcium carbonate-starch complex sol；
（2）3kg acrylamides and 0.5kg Tween-80s are added into 100kg steps（1）Obtained calcium carbonate-starch is combined molten
It is well mixed in glue and pH is adjusted to 7, then adds 0.1kg initiators, in 70 DEG C of stirring reaction 2h under nitrogen protective condition,
Cool down, filter, dry and grind uniform, obtain papermaking special calcium carbonate filler.
The step（1）In speed of agitator be 1000r/min.
The step（1）In whipping temp be 30 DEG C.
The initiator is potassium peroxydisulfate.
The starch is cornstarch.
