Description
Technical field
The present invention relates to a kind of manufacture method of literature and art book paper.
Background technology
Literature and art book paper is domestic at present all by import as high-grade books, picture album paper, and it requires paper bulky and soft
It is soft(It is big that paper requirement deflection is used different from conventional book), printed that machine performance is good, anti-silk specification when adapting to lithographic printing is strong
Degree requires that paper has also required good exquisiteness and feel, and paper is clean, color and luster is soft, while requires surface strength height, can be full
Sufficient high speed printing, printing color is true to nature, and texture is strong.
As our people's living standard improves, more and more higher, especially some high-end print paper are required to paper quality,
It is required that books are light and papery is soft, this proposes very hang-up to paper production, and papery gently then wants bulk high, mechanical pulp dosage
It can increase, it is stiff to inevitably result in papery, meanwhile, smoothness must reduce, and cause paper not fine and smooth enough, and feel is poor, printing
Effect especially color printing effect is bad.
Present invention seek to address that problem above, meets that the country is high-end and is required with paper, mainly take following technology:(1)Slurry
In, preferably beating degree is not high, and bulk is high, the good chemi-thermo-mechanical pulp of flexibility(CTMP), optimize pulping technique, to obtain
Well disappear latent effect, while mitigates CTMP mashing degree, improves sheet softness and improves bulk;(2)Using cellulase
The mashing of needlebush slurrying is aided in, obtains good strength simultaneously, reduces fibre cutting;(3)Add esterquat surfactant,
Improve sheet softness and bulk;(4)Top sizing adds the cruel potassium of carbonic acid, improves paper dimensional stability and flatness, improves paper
Open lithographic printing and cross machine performance(Anti- silk is the horizontal longitudinal direction as when printing of paper, and machine performance requirement height is crossed to paper);(5)It is excellent
Change paper fibre orientation angle and deflection aspect ratio, reduce paper lateral stiffness;(6)Using calcium stearate class Cypres, change
Kind paper feel;(7)More preferable bulk is obtained using inorganic bulk agent.
The content of the invention
It is an object of the invention to provide a kind of manufacture method of the paper such as high-grade books, picture album, picture scroll, it requires its requirement
Paper bulky and softness(It is big that paper requirement deflection is used different from conventional book), it is good to print machine performance, when adapting to lithographic printing
The requirement of anti-silk dimensional strength, paper also required good exquisiteness and feel, and paper is clean, color and luster is soft, while requires table
Surface intensity is high, can meet high speed printing, printing color is true to nature, and texture is strong.
To realize requirements above, the present invention uses following technical scheme, a kind of manufacture method of literature and art book paper, with bleaching
Sulfate softwood pulp(NBKP), bleaching chemithermo mechanical pulp(CTMP)And alkaline hydrogen peroxide bleaching aspen mechanical slurry
(APMP)Carried out as fibrous raw material with copying, product is sieved through underflow, condiment, punching slurry, desanding degasification, starching, fine screen, wet end are dehydrated into
Type, squeezing, preceding drying, top sizing, rear drying, press polish, batch, packing forms, it is characterised in that:
(1)Slurry is bleached sulphate softwood pulp(NBKP), bleaching chemithermo mechanical pulp(CTMP)And alkaline peroxide
Change hydrogen bleaching aspen mechanical slurry(APMP), slurry weight, which matches, is:NBKP10~20%; APMP10-30%;CTMP50-80%.Its
In, not being beaten CTMP beating degrees 24-30SR, CTMP needs, bulk high product not high from beating degree, its pulping temperature need
Control is disappeared latent with improvement at 80-90 DEG C, is sufficiently spread out CTMP fibers.In addition, CTMP again through appropriate mashing, be beaten only with
Light knife processing, prevents that wire-dividing broom purification is excessively good, causes paper sheet stiffness excessive, and CTMP beating degrees are controlled in 28-34SR after mashing,
APMP is used from pulp production, beating degree 51-55SR;
(2)Using cellulase auxiliary needlebush slurrying mashing, obtain good strength simultaneously, reduce fibre cutting, dosage is
0.05-0.20kg/t is starched;Needlebush slurrying beating degree is controlled in 40-46SR;
(3)Esterquat surfactant is added, improves sheet softness and bulk, dosage is starched for 0.5-2.0kg/t, added
Access point be fine screen before, i.e. before one section of selectifier;
(4)Top sizing adds the cruel potassium of carbonic acid, improves paper dimensional stability and flatness, improves paper lithographic printing and crosses machine performance
(Anti- silk is the horizontal longitudinal direction as when printing of paper, and machine performance requirement height is crossed to paper), dosage is 1.0-3.0kg/t slurries, is added
In surface sizing starch;
(5)Optimize paper fibre orientation angle and deflection aspect ratio, reduce paper lateral stiffness;2.9- is arrived into the control of deflection aspect ratio
Between 3.3, paper lateral stiffness is reduced.Because books flexibility is mainly reflected in horizontal flexibility, and horizontal flexibility can lead to
Cross control lateral stiffness(It is opposite with flexibility)Method realizes, Cultural Paper deflection aspect ratio can typically be less than 2.8, horizontal to reduce
To deflection, it is to compare effective means to improve deflection aspect ratio;
(6)Using calcium stearate class Cypres, improve paper feel, dosage is starched for 0.5-1.5kg/t, is added in top sizing
In starch;
(7)More preferable bulk is obtained using inorganic bulk agent, reaches light paper requirement, dosage is that 2-5kg/t is starched, addition point for
Stock tank.
Product major parameter produced by the present invention is:Quantitative 55-65g/m2, the dynamic mill coefficient of friction of paper are less than 0.4;Paper
Longitudinal deflection 45-60mN, horizontal Ting Du≤25mN;Surface strength >=1.0m/s;Smoothness >=40s;Bulk >=1.6cm3/g;
Fracture length >=4000m;Paper color is white, whiteness 76-80%ISO.
Main innovation point of the present invention is:
(1)It is preferred that bleach chemithermo mechanical pulp(CTMP), CTMP is beaten only with light knife from beating degree not high product
Reason, prevents that wire-dividing broom purification is excessively good, causes paper sheet stiffness excessive;
(2)Using cellulase auxiliary needlebush slurrying mashing, obtain good strength simultaneously, reduce fibre cutting;
(3)Esterquat surfactant is added, improves sheet softness and bulk;
(4)Top sizing adds the cruel potassium of carbonic acid, improves paper dimensional stability and flatness, improves paper lithographic printing and crosses machine performance;
(5)Deflection aspect ratio is controlled between 2.9-3.3(Cultural Paper aspect ratio is often in 1.8-2.6), it is horizontal to reduce paper
Deflection;
(6)Using calcium stearate class Cypres, improve paper feel;
(7)More preferable bulk is obtained using inorganic bulk agent.
