Description
Technical field
The present invention relates to a kind of Cypres, this Cypres preparation method and apply above-mentioned Cypres and carry out the obtained sized paper of applying glue.
Background technology
What surface sizing agent for paper making adopted is AKD (alkyl ketene dimer), gum rosin, PVA(polyvinyl alcohol) etc., but these Cypres often can only improve paper water repelling property or can only improve the intensity of paper surface, can not take into account paper WATER RESISTANCE and surface strength of paper two indices simultaneously.
At present, if desired improve paper WATER RESISTANCE and surface strength of paper in prior art, general needs adds at least two kinds of medicines, complex manufacturing, and cost increases simultaneously.
Summary of the invention
In view of this, be necessary the preparation method providing a kind of Cypres, the Cypres that the method obtains can take into account paper WATER RESISTANCE and surface strength of paper simultaneously.
In addition, there is a need to the Cypres providing a kind of preparation method applying above-mentioned Cypres to obtain.
In addition, there is a need to provide a kind of apply above-mentioned Cypres and carry out the obtained sized paper of applying glue.
A preparation method for Cypres, it comprises the steps:
Farinaceous size is provided, this farinaceous size is heated to starch gelatinization temperature and carries out boiling;
In the farinaceous size after above-mentioned boiling, add LCFA make mixed serum, the addition of this LCFA is the 0.1%-10% of starch weight;
Above-mentioned mixed serum is adjusted to alkaline environment, after described LCFA fully dissolves, then adjusts above-mentioned mixed serum pH value in the scope of 2-11, obtained described Cypres.
The Cypres that the preparation method applying above-mentioned Cypres obtains, this Cypres contains starch and LCFA, and the addition of this LCFA is the 0.1%-10% of starch weight.
A kind of sized paper applied above-mentioned Cypres and obtain.
Cypres preparation method provided by the invention, by to add in LCFA to farinaceous size and to regulate the pH value of these slurries, utilize LCFA under pH value, have the Cypres drawn prepared by different forms and two characteristics of good water repelling property of itself having, be applied to surface strength and water repelling property that paper surface can improve paper simultaneously.In addition, the method that the present invention prepares top sizing has simple to operate, medicine addition and reduces and low cost and other advantages.
Detailed description of the invention
A preparation method for Cypres, it comprises the steps:
(1) provide farinaceous size, this farinaceous size is heated to starch gelatinization temperature and carries out boiling.
This step makes amidin for be added water by starch, then this amidin is warming up to starch gelatinization temperature (as 95 DEG C and more than) carry out boiling until the obtained required farinaceous size of starch gelatinization.
This starch is selected from least one in tapioca, cornstarch and wheaten starch.
(2) in the farinaceous size after above-mentioned boiling, add LCFA and make mixed serum, the addition of this LCFA is the 0.1%-10% of starch weight.
Described LCFA refers to the aliphatic acid of carbon atom more than 12 in fatty acid molecule structure in carbochain.Carbon atom number in the carbochain of this LCFA is within the scope of 12-20.Preferably, described long-chain fat includes but not limited to sour laurate, myristic acid, palmitic acid, oleic acid and stearic acid.
Preferably, the addition of described LCFA is the 0.5%-3% of starch weight.
(3) above-mentioned mixed serum is adjusted to alkaline environment, after described LCFA fully dissolves, then adjusts obtained described Cypres in above-mentioned mixed serum pH value to the scope of 2-11.
After described LCFA is added into above-mentioned farinaceous size, fully to stir and the pH adjusting mixed serum fully dissolves to alkaline environment to enable this LCFA.Preferably, the pH referring to this mixed serum of the mixed serum of this alkaline environment is 11.
Preferably, after described LCFA fully dissolves, then regulate the pH value of this mixed serum in the scope of 5-11.
The LCFA that the present invention adds has following two performances: the first, the chain alkyl of LCFA has splendid water repelling property; The second, LCFA presents different shape under the environment of different pH, concrete, when LCFA is in the basic conditions in threadiness, when LCFA then shrinks under acidic or neutral conditions in cotton-shaped.
The present invention makes full use of two characteristics of above-mentioned LCFA, to be added in farinaceous size and to be prepared into Cypres, enabling paper have outstanding water repelling property and surface strength after this Cypres is applied to paper simultaneously.Concrete principle is as follows:
LCFA is utilized to present fibrous characteristic under alkaline environment, be added in farinaceous size at it and regulate this mixed serum to alkaline environment afterwards and make it abundant dissolving, part LCFA can enter into the inside of starch helical structure, and remaining LCFA relies on the filamentary structure of self to be distributed between starch molecule with the wrapped of network skeleton;
After LCFA fully dissolves, regulate the pH value of mixed serum to shrink at the LCFA of the inside of starch helical structure and the outside that is wrapped in starch molecule to make injection again, and it is more tight to make starch be combined with LCFA, there is the surface strength that sizing agent that this starch of combining closely and LCFA make significantly improves paper to paper surface.
So, obtained Cypres applying glue, to paper surface, can make paper have outstanding surface strength, in addition, because this LCFA has outstanding water repelling property, therefore Cypres applying glue this paper to paper surface containing LCFA also has outstanding water repelling property.Therefore, compared to prior art, surface strength and the water repelling property of paper after Cypres provided by the invention is applied to paper surface, can be improved simultaneously.
The present invention also provides the preparation method in a kind of Cypres described above the Cypres obtained, and this Cypres comprises starch and LCFA, and the addition of this LCFA is the 0.1%-10% of starch weight.
The present invention also provides a kind of and applies the obtained sized paper of above-mentioned Cypres.
Below by embodiment, the present invention is specifically described.
