Abstract
The invention relates to a preparation method of a modified starch surface sizing agent and belongs to the technical field of sizing agent preparation. The preparation method includes firstly, subjecting cassava starch to oxidation treatment by hydrogen peroxide and an ethanol solution; then, performing sulfonation treatment under the condition of ice-water bath with chlorosulfonic acid and glacial acetic acid added so as to obtain modified cassava starch; thirdly, subjecting Bacillus stearothermophilus to selective culture by a selective culture medium to obtain a bacterium, and modifying the modified cassava starch by the bacterium to enhance hydrophobicity; finally, adding natural chitin both as a binding agent and for enhancing an antibacterial effect so as to obtain the modified starch surface sizing agent. The modified starch surface sizing agent prepared according to the preparation method is less prone to mildewing, a coated film layer is less prone to cracking and damping, and accordingly epoxy strength and water resistance of paper are improved.
Description
Technical field
The present invention relates to a kind of preparation method of modified starch Cypres, belong to sizing agent preparing technical field.
Background technology
With the continuous development of current papermaking, printing and association area, paper and paperboard surface are improved for Cypres
The requirement of performance and printing adaptability also more and more higher.The preparation of Cypres is increasingly paid attention to by paper-making industry, it with
Papermaking material structure adjustment, development trend of mode of printing variation, high speed and paper products high-quality etc. are relevant, so table
The effect of face applying glue and its advantage seem especially prominent.Top sizing processes and directly acts on paper surface, overcomes interior interpolation
Paper machine systemic contamination that auxiliary agent exists, foaming, high temperature are manufactured paper with pulp degree of sizing low sequence of operations sex chromosome mosaicism.
Conventional Cypres have alkyl ketene dimer sizing agent, and it has preferable water repelling property, but there is
Poor with the affinity of fiber, the contribution to ring pressure and deflection is little, emulsion facile hydrolysis impact sizing efficiency within storage period, and
There is the maturation period, that is, after machine under paper, certain time to be crossed can be only achieved maximum degree of sizing, due to inhaling within the maturation period
Receiving moisture makes ring crush intensity decline by a big margin, and so that water-resistance has also been declined simultaneously.It is proposed that using natural polymer
Cypres（Mainly starch and its modifier）, starch and its modifier are the most frequently used carriers, modified starch with
The adhesion of fiber more preferably, has certain improvement result to paper products hair and powder dropping, but after being dried, film layer embrittlement is easy to crack, after making moist
Surfaces of tacky, affects water-resistance and the ring crush intensity of paper, and in addition starch easily goes mouldy, and emulsion can be caused to go bad, therefore applying glue
Effect is not often good enough.
Content of the invention
The technical problem to be solved：Film layer embrittlement after being dried for existing natural polymer Cypres
Easy to crack, surfaces of tacky after making moist, thus affecting water-resistance and the intensity of paper, and easily going mouldy, affecting asking of sizing efficiency
Topic, the present invention is carried out after oxidation processes to tapioca first with hydrogen peroxide and ethanol solution, adds chlorosulfonic acid and ice vinegar
Acid, under the conditions of ice-water bath, carries out sulfonation process, obtains modified tapioca starch, finally utilizes screening and culturing medium to stearothermophilus bud
Spore bacillus carries out screening and culturing, and the bacterial classification of acquisition is modified to modified tapioca starch, increases hydrophobicity, finally adds natural
Chitin increases antibacterial effect as while adhesive, thus modified starch Cypres are obtained, prepared by the present invention changes
Property starch surface sizing agent be difficult to go mouldy, and the film layer that formed after being coated with is not easy to crack and not moisture-sensitive, improves the ring of paper
Oxygen intensity and water repelling property.
For solving above-mentioned technical problem, the technical solution used in the present invention is：
（1）Count by weight, take 40～50 portions of tapiocas, 60～70 parts of mass fractions to be 70% ethanol solution, 12～16

Tapioca, mass fraction be that 70% ethanol solution and mass fraction are put into agitator, thermometer for 15% hydrogen peroxide
And in the four-hole boiling flask of dropping funel, and four-hole boiling flask is placed in water-bath, design temperature is 55～60 DEG C, with 300r/min
Stirring 1～2h；
（2）After above-mentioned stirring terminates, four-hole boiling flask is placed in ice-water bath, then by the chlorosulfonic acid of above-mentioned parts by weight and ice vinegar
Acid mixes, and obtains mixed liquor, and is added dropwise in four-hole boiling flask using dropping funel, and control rate of addition is 2/s, with
250r/min is stirred, and continues stirring 3～6h, subsequently take out four-hole boiling flask, using 1.5mol/L hydrogen after being added dropwise to complete
In sodium hydroxide solution regulation four-hole boiling flask, mixture pH is to neutrality；
（3）After above-mentioned pH is adjusted, four-hole boiling flask is put standing 1～2h at room temperature, then carry out filtration under diminished pressure, collect filter residue, and
2～3 times of deionized water of filter residue and its quality is mixed, then is spray-dried, collect dried object, obtain modified para arrowroot
Powder, standby；
（4）Count by weight, take 42～44 portions of sucrose, 32～36 parts of peptones, 26～28 parts of yeast extracts, 7～9 parts of bright ammonia
Acid, 1～2 part of streptomysin, 3～6 parts of petroleum ethers and 2～4 parts of ammonium citrates, stir, and put into sterilized in high-temperature sterilization pot
Sterilization, obtains screening and culturing medium, by inoculum concentration 10～15%, bacillus stearothermophilus is seeded to screening and culturing medium, and will connect
Screening and culturing medium after kind is placed in constant incubator, and design temperature is 57～62 DEG C, cultivates 20～24h；
（5）After culture terminates, screening and culturing medium is taken out, screen media surface using sterilized water drip washing, until its surface
No mycelia, collection leacheate, in mass ratio 1:3～1:5, by leacheate and step（3）Standby modified tapioca starch puts into appearance
Mix in device, and by after container standing 2～3h under the conditions of 57～62 DEG C, add in container leacheate quality 30～
40% chitin, then container is placed in sterilizing under ultraviolet sterilizing lamp, you can obtain modified starch Cypres.
The application process of the present invention：First fluting medium is laid on glass plate on request, and one end is fixed
Afterwards, modified starch Cypres prepared by the present invention are spread evenly across on the body paper after fixing, control the amount being coated with to be 25
～35g/m2, after end to be coated, after the paper natural air drying 3～5min after applying glue, then it is placed in temperature for 90～105 DEG C of bakings
1～3min is dried in dry machine.
