Abstract
The invention discloses a kind of micro- painting techniques of papermaking nanometer, and following coating are applied on the paper machine with size press, and formulation for coating material includes：Nanoparticle, starch, styrene-acrylic latex, calcium stearate series lubricant agent, brightening agent.A kind of micro- painting technique of papermaking nanometer is provided, lid ability is weak, printing color reduction shortcoming to overcome the problems, such as conventional surface sizing, while improving paper surface exquisiteness, improves paper sense of touch, to improve paper product class.
Description
Technical field
The present invention relates to pulp technology for making paper, in particular to the present invention relates to a kind of micro- painting technologies of papermaking nanometer.
Background technique
As China's living standard improves, requirement of the user to hectograph paper product is also higher and higher, and emphasis is to want among these
Improve paper printing effect, improves paper sense of touch and reading comfort.Offset paper production in China's often uses starch surface sizing,
But traditional starch surface sizing covering power is weak, when printing, ink penetration is excessive, causes print gloss low, printing color
Color reducing property is poor, and realizes high-quality printing effect, and paper surface generally requires to be coated with, and coating needs special painting to lay
Standby, domestic culture paper is containing the few of coating apparatus.In addition, domestic coating Cultural Paper（Such as art paper, lightweight paper）, because of glossiness
Excessively high, tightness is too big, and smell is too dense, tends not to the print request for meeting high-end books.Exploitation nanometer is glued in conventional surface
Coating technology is exactly to solve the problems, such as that conventional surface sizing covering power is weak, restoring shortcoming.
Summary of the invention
It is an object of the present invention to provide a kind of micro- painting techniques of papermaking nanometer, and to overcome, conventional surface sizing lid ability is weak, prints
Brush color rendition is short of problem, while improving paper surface exquisiteness, improves paper sense of touch, to improve paper product class.
In order to achieve the above object, the technical solution adopted by the present invention is that：A kind of micro- painting technique of papermaking nanometer, feature exist
In using following coating on the paper machine with size press, formulation for coating material includes：Nanoparticle：5-20 parts, starch：70-
90 parts, styrene-acrylic latex：5-10 parts, calcium stearate series lubricant agent：0.5-1.5 parts, brightening agent OBA：1-2 parts.
Preferably, the coating ph value is adjusted to 8.0-8.5, solid content 10-15%, viscosity:4-10cpas.
Preferably, resin added or coating weight:4-6g/m2.
Preferably, nanoparticle is the nano inorganic particles of bigger serface, porous structure.
Preferably, nanoparticle is porous silicate nanometer particle.
A kind of nano coating offset printing paper is made of the micro- painting technique of above-mentioned papermaking nanometer.
Beneficial effects of the present invention：Overcoming the problems, such as conventional surface sizing, lid ability is weak, printing color reduction shortcoming, changes simultaneously
Kind paper surface exquisiteness, improves paper sense of touch, to improve paper product class：
1, compounding 5-20% nano inorganic particles can largely adsorb print due to its great specific surface area, porous structure
Brush ink, so that ink is made to be retained in paper surface as far as possible, meanwhile, porous structure is conducive to solvent components in ink and penetrates into, from
And improve drying property when printing.
2, nano material is introduced in top sizing, due to this nano particle large specific surface area, the requirement to adhesive is high,
Otherwise it is low to be also easy to produce surface strength, prints Discussion of Picking, for this purpose, using the styrene-acrylic latex and 70- of 5-10% in coating
90% starch is as adhesive, and to improve surface strength, and emission of bad smell is effectively reduced in the presence of nano particle, and reading can be improved
Comfort.
3, nanoparticle exists as colloidal form, and brightening agent and traditional helps strong type anionic surface sizing agent
It is compatible that the brightening agent of 1-2% can be compounded in coating very well, meanwhile, using the coating formula of nanometer, viscosity of the coating specific surface is applied
The viscous decline 31.8% of amylopectin liquid, paper machine size press roller roll surface film forming is more preferable, meanwhile, nanoparticle is compatible with brightening agent (OBA)
Property is also very good.
4, the calcium stearate series lubricant agent that 0.5-1.5% is compounded in coating, can improve the rheological characteristic of coating, reduce paper
Coefficient of friction improves paper feel.
5, product major parameter produced by the present invention is quantitative 50-120g/m2, to improve paper printing effect, in hectograph
The indignant thought of print gloss is introduced in paper production, to improve paper feel, introduces the indignant thought of coefficient of friction, wherein print gloss >=
20%, static friction coefficient is lower than 0.4, moves mill coefficient of friction and is lower than 0.3；Surface strength >=1.0m/s；Smoothness >=40s；Blotting
Property：30-40%.After being formulated using nano coating, compared with general surface sizing, paper roughness decline, smoothness rises, and moves
Frictional decrease, in the consistent situation of sheet gloss degree, print gloss is higher, in addition ink absorption, surface strength difference
Less.This guarantees the sheet gloss of customer requirement is low（Protect eyes）, while printing color reduction preferably requires, simultaneously
It can guarantee high speed rotary printing again（Without drying equipment）Not set-off, the requirement not lost powder.
