Description
Technical field
The present invention relates to a kind of production method of high-grade raw white offset printing paper.
Background technology
At present in traditional paper-making process, if meeting, papery is soft, low gloss requirement, generally require to mix with high mixture ratio
The mechanical pulp of amount, and such fiber surface is coarse, poor plasticity, product feel is poor, and exquisiteness is poor, and color printing effect is poor；If will
Meet good hand touch, exquisiteness is good and color printing effect is required well, then generally require based on chemical pulp, and it is light to be so difficult papery
Soft, low gloss and the simple requirement of printing.But carry forward the use such as book magazine, personage's biography, top-quality book of traditional Chinese culture
Paper is usually to use high-grade raw white offset printing paper, it is desirable to which papery is soft, low gloss, and wants former good feel, printing simpleness,
Third dimension is strong, and color printing color rendition degree is high.Simultaneously, it is desirable to which surface strength of paper can meet 8 color business rotary printing requirements.Cause
This, domestic this kind of product is much dependent on import.
The content of the invention
It is an object of the invention to provide a kind of production method of high-grade raw white offset printing paper, product papery is soft, low light
Pool, and good feel is required, printing is simple, and third dimension is strong, and color printing color rendition degree is high, and picking speed is high, Neng Gouyong
Carry forward traditional Chinese culture book magazine etc. and use paper.
To realize requirements above, the present invention uses following technical scheme, a kind of production of high-grade raw white offset printing paper
Method, it is characterised in that：With bleached sulphate softwood pulp NBKP, bleached sulphate hardwood chemical pulp LBKP and alkali
Property hydrogen peroxide bleaching aspen mechanical slurry APMP carried out with copying as fibrous raw material, product is starched through underflow sieve, condiment, punching, desanding is removed
Gas, starching, fine screen, wet end dehydration forming, squeezing, preceding drying, top sizing, rear drying, press polish, batch, packing forms, its
In：Each slurry by weight percentage, bleached sulphate softwood pulp NBKP 30~50%；Bleached sulphate deciduous
Learn slurry LBKP20~30%；And alkaline hydrogen peroxide bleaching aspen mechanical slurry APMP 25-45%.
In order to improve paper exquisiteness, raising makes paper softr to the present invention, bleached sulphate softwood pulp
NBKP and bleached sulphate hardwood chemical pulp LBKP adds the sodium carboxymethylcellulose of 0.5-1.0kg/t slurries in mashing respectively
CMC, with reinforcing fibre wire-dividing broom purification.
The present invention improves paper exquisiteness, alkaline hydrogen peroxide bleaching aspen mechanical slurry to improve surface strength of paper
APMP beating degrees are controlled in 53-570SR。
Paper papery is soft, low gloss requirement, Paper bulk control to 1.35cm to meet for the present invention3/ more than g.Meanwhile,
Surface sizing starch consumption 20-30kg/t paper.
The present invention adds 1-3kg/t paper to make surface strength of paper meet 8 color business rotary printing requirements in top sizing
Polystyrene acrylate.
To improve paper feel, top sizing adds 1-3kg/t paper lubricants to the present invention, and lubricant Main Ingredients and Appearance is hard ester
Sour calcium.
To improve printing effect, paper smoothness is controlled to more than 50s the present invention.
The present invention is soft to make paper visually observe tone, does not use brightening agent, is not mixed colours.
Alkaline hydrogen peroxide bleaching aspen mechanical slurry APMP of the invention is that aspen fibers by using silicon raw material uses PRC-APMP slurrying
Technique is made, the whiteness 75-78%ISO of slurry；Bleached sulphate softwood pulp, BRATSK beating consistency 3.5-
4.5%, beating degree is respectively 40-50 after beating degree0SR and 30-400SR。
Obtained product major parameter of the invention is quantitative 70-80g/m2, to improve paper feel, introduce coefficient of friction indignant
Read, wherein, static friction coefficient is less than 0.4, moves mill coefficient of friction and is less than 0.35；Surface strength >=1.0m/s；Smoothness >=50s；
Bulk >=1.35cm3/g；Paper color is white, whiteness 82-84%ISO；Longitudinal fracture length >=5000m.
Main innovation point of the present invention is：Using part APMP, so that paper more bulky.To improve paper exquisiteness,
The NBKP and LBKP mashing sodium carboxymethylcellulose that addition 0.5-1.0kg/t is starched respectively（CMC）, with reinforcing fibre wire-dividing broom purification,
Meanwhile, APMP beating degrees are different from domestic other producer's products and (are generally not more than 450SR), 53-57 is reached0SR.To improve paper
Feel, top sizing addition 1-3kg/t paper lubricants, and the indignant thought of coefficient of friction is introduced in Cultural Paper production, wherein, static friction
Coefficient is less than 0.4, moves mill coefficient of friction and is less than 0.35, and this is domestic initiation.Rotated to make surface strength of paper meet 8 colors business
Print request, the polystyrene acrylate of 1-3kg/t paper is added in top sizing.
The high-grade raw white offset printing paper of the inventive method gained, papery is soft, low gloss, and feel is good, and printing is simple, stands
Body-sensing is strong, and color printing color rendition degree is high, and picking speed is high, can act as carrying forward the use such as traditional Chinese culture book magazine
Paper.
