Abstract
A kind of method for making colored laser paper and paper, it is with slurry that the method comprising the steps of, mashing, manufactures paper with pulp, top sizing, selection broad-leaved chemical bleaching NBSK with slurry, and in top sizing step, dispersant B is added in size-press starch.The paper is made up of broad-leaved chemical bleaching NBSK, it is characterised in that：Ash content is 5% 30%, moisture content is 4% 7%, smoothness 8sec/10cc.The paper is smooth, avoids paperboard, sea surface oil slick good film-forming property, still can ensure high image quality requirement in flying print.
Description
Technical field
The present invention relates to paper technology, especially a kind of method for making colored laser paper and paper.
Background technology
As paper technology continues to develop, paper plant develops a series of paper kinds for meeting particular customer, and its sharp paper of prizing should
Transport and give birth to；The offer of life grade now, people are to printing effect quality requirements more and more higher.Common print paper color it is bright-coloured
Degree, saturation degree and everyway can not meet the requirement of modern printer, due to the sharp paper of coloured silk optics physical property, surface physical property,
Intensity physical property etc. is different from common print paper, and its printing effect is lucuriant in design, image fidelity.
Common print is maintained with paper typically in the direct coating surface size-press starch of paper surface and conventional surface sizing agent
Surface strength of paper and certain water repelling property, due to the appearance of present high product printer, paper requirement is not only met
These requirements can, also require at a high speed, high-quality printing when, can it is quick cross machine, non-paperboard, printed matter surface oil film into
Film will get well, and stronger than common paper in paper surface bond strength, so just can guarantee that Paper Printing come out effect compared with
It is excellent, allow picture and text to there is kind to appear vividly in the effect on paper.
The content of the invention
In order to overcome technical problem of the prior art, the invention provides a kind of method for making colored laser paper and paper, the paper
Both the requirement of water repelling property had been met, had met again at a high speed, effect when high-quality is printed.
A kind of method for making colored laser paper, comprises the following steps：
Step a：It is with slurry, from broad-leaved chemical bleaching NBSK, dissipate and add additive A during starching；
Step b：Mashing, manufactures paper with pulp；
Step c：Top sizing, dispersant B is added in size-press starch.
Preferably, the additive A is ethyl acrylate or acrylates.
Preferably, additive A 4-8 hours before manufacturing paper with pulp add.
Preferably, freedom is 300-500ml after the broad-leaved chemical bleaching NBSK mashing.
Preferably, the dispersant B is cellulose ethers polymer, one of CMC, PVA.
Preferably, the size-press starch is 20-50kg/t, dispersant B 10-30kg/t.
Preferably, the resin added of the step c is 3-5gsm.
Preferably, step d can also be included：Into paper whiteness.
A kind of paper, it is made up of broad-leaved chemical bleaching NBSK, it is characterised in that ash content is 5% -30%, moisture content is
4%-7%, smoothness 80sec/10cc.
Preferably, two sulphur OBA are added in the paper, surface is six sulphur OBA.
After implementing above technical scheme, there is following technique effect.
Additive A is added during slurry is dissipated, for improving smoothness, makes surface smoother, avoids paperboard, resend
Phenomenon occurs, and meets the requirement of flying print.
Dispersant B is added during top sizing, for improving sur-face peeling intensity, and sea surface oil slick film forming
It is good, it still can ensure high image quality in flying print.
Six sulphurs are being used using two sulphur OBA, surface into during paper whiteness, inside adding, are reducing electric charge to control system
Influence.
Embodiment
It is described further with reference to embodiment.
Embodiment one
It is with slurry：From broad-leaved chemical bleaching NBSK 100% (such as Eucalyptus, Acacia, poplar), added during slurry is dissipated
The additive A (ethyl acrylate, acrylates etc.) of 1-5kg/t paper.Due to broad-leaved chemical bleaching NBSK cell membrane
It is relatively thin, roughness is low, not only uniformly, can also improve the smoothness of paper, additive A rises fiber for profit, improves lifting
Smoothness, additive A dosage can appropriately adjust according to paper quality, the 4-8 hours preferably before paper machine is manufactured paper with pulp,
To meet that fiber fully contacts with medicine；To the section drop of refining energy consumption and system reservation and some guarantors after fibre swelling
Stay and help
The influence for having positive aspects drops in agent section.
Mashing, manufactures paper with pulp：Due to requiring that evenness index request is higher, preferably dissociate after the mashing of broad-leaved chemical bleaching NBSK
Spend for 300~500ml.Due to being manufactured paper with pulp using leaf wood chemistry bleached kraft pulp, paper strength is actual change copy before have very
Big change, therefore suitable control speed is wanted during manufacturing paper with pulp；Because smoothness requirements are higher, the moisture control for process of manufacturing paper with pulp,
The control of calendering pressure and calendering temperature is particularly important.
Top sizing：In size-press starch, it is (fine that dispersant B is added in (cornstarch, tapioca, wheaten starch)
Tie up plain ether polymer, CMC, PVA) improve sur-face peeling intensity, size-press starch 40-50kg/t paper, dispersant B
Add 20-25kg/t paper, it is necessary to assure paper surface there are 3-5gsm resin addeds.
Into paper whiteness：Require higher into paper whiteness, inside add and six sulphur OBA are used using two sulphur OBA, surface, it is appropriate to be come with this
Control system electric charge, avoid a large amount of uses of fluorescer very big on System Charges influence, whole manufacture paper with pulp can be had a negative impact.
It is preferred that interior add two sulphur OBA 4-10kg/t, the sulphur OBA 4-10kg/t of surface six.
Into paper ash be divided into 25% -30%, moisture content be 4% -7%, smoothness 80sec/10cc.
Embodiment two
The present embodiment and the difference of embodiment one are, in top sizing step, size-press starch 30-40kg, dispersant B is
15-20kg/t paper.
Into paper ash be divided into 20% -25%, moisture content be 4% -7%, smoothness 80sec/10cc.
Embodiment three
The present embodiment and the difference of embodiment one are, in top sizing step, size-press starch is 20-30kg/t paper, disperse
Agent B is 10-15kg/t paper.
Into paper ash be divided into 15% -20%, moisture content be 4% -7%, smoothness 80sec/10cc.
It should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to preferable
The present invention is described in detail embodiment, it will be understood by those within the art that, can be to the technology of the present invention
Scheme is modified or equivalent substitution, and without departing from the spirit and scope of technical solution of the present invention, it all should cover in this hair
Among bright right.
