The production method is characterized in that bleached sulfate needlebush chemical pulp NBKP, bleached sulfate broad-leaf wood chemical pulp LBKP and alkaline hydrogen peroxide bleached cotton wood mechanical pulp APMP are used as fiber raw materials to be mixed, and a product of the top-grade book white offset printing paper is prepared by virtue of thick slurry screening, mixing, slushing, sand and gas removal, sizing, fine screening, netted dehydrating and forming, squeezing, pre-drying, surface gluing, post-drying, press polishing, coiling and packing, wherein each sizing agent comprises the following components by weight percent: 30 to 50 percent of bleached sulfate needlebush chemical pulp NBKP, 0 to 30 percent of bleached sulfate broad-leaf wood chemical pulp LBKP, and 25 to 45 percent of alkaline hydrogen peroxide bleached cotton wood mechanical pulp. The top-grade book white offset printing paper obtained in the method is soft in paper tissue, low in gloss, good in hand feeling, excellent in quality of a printed product, high in three-dimensional performance, high in colorful reduction degree, high in printing surface strength and capable of being used as paper for developing traditional Chinese culture, books, magazines and the like.
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 will meet, papery is soft, low luster requirement, and often need to mix the mechanical pulp of joining high mixture ratio amount, and this type of fiber surface is coarse, poor plasticity, product feel is poor, and exquisiteness is poor, color printing weak effect; If meet good hand touch, the good and effective requirement of color printing of exquisiteness, then generally need based on chemical pulp, and be difficult to that papery is soft like this, low luster and the simple requirement of printing.But carrying forward the paper usings such as the book magazine of traditional Chinese culture, personage's biography, top-quality book is generally adopt high-grade raw white offset printing paper, require that papery is soft, low luster, and want former good feel, printing is simple, and third dimension is strong, and color printing color rendition degree is high.Meanwhile, require that surface strength of paper can meet 8 look business rotary printing requirements.Therefore, a lot of all dependence on import of this series products domestic.
Summary of the invention
The object of this invention is to provide a kind of production method of high-grade raw white offset printing paper, product papery be soft, low luster, and require good feel, printing is simple, and third dimension is strong, and color printing color rendition degree is high, picking speed is high, can as carrying forward the paper usings such as traditional Chinese culture book magazine.
For realizing above requirement, the present invention adopts following technical scheme, a kind of production method of high-grade raw white offset printing paper, it is characterized in that: with bleached sulphate softwood pulp NBKP, bleached sulphate hardwood chemical pulp LBKP, and alkaline hydrogen peroxide bleaching aspen mechanical slurry APMP carries out joining copying as fibrous raw material, product sieves through underflow, condiment, punching slurry, desanding degasification, starching, fine screen, wet end dehydration forming, squeezing, front drying, top sizing, rear drying, press polish, batch, packing forms, wherein: each slurry by weight percentage, bleached sulphate softwood pulp NBKP30 ~ 50%, bleached sulphate hardwood chemical pulp LBKP20 ~ 30%, and alkaline hydrogen peroxide bleaching aspen mechanical slurry APMP25-45%.
The present invention is in order to improve paper exquisiteness, improving makes paper softr, bleached sulphate softwood pulp NBKP and bleached sulphate hardwood chemical pulp LBKP adds the sodium carboxymethylcellulose CMC of 0.5-1.0kg/t slurry respectively when pulling an oar, with reinforcing fibre wire-dividing broom purification.
The present invention, for improving surface strength of paper, improves paper exquisiteness, and alkaline hydrogen peroxide bleaching aspen mechanical slurry APMP beating degree controls at 53-57
0sR.
In order to meet, paper papery is soft, low luster requirement in the present invention, and Paper bulk controls to 1.35cm
3/ more than g.Meanwhile, surface sizing starch consumption 20-30kg/t paper.
The present invention meets 8 look business rotary printing requirements for making surface strength of paper, adds the polystyrene acrylate of 1-3kg/t paper at top sizing.
The present invention is for improving paper feel, and top sizing adds 1-3kg/t paper lubricant, and lubricant Main Ingredients and Appearance is calcium stearate.
The present invention is for improving printing effect, and paper smoothness controls to more than 50s.
The present invention, for making paper perusal tone soft, does not use brightening agent, does not mix colours.
Alkaline hydrogen peroxide bleaching aspen mechanical slurry APMP of the present invention is that aspen fibers by using silicon raw material adopts PRC-APMP pulping process to make, the whiteness 75-78%ISO of slurry; Bleached sulphate softwood pulp, BRATSK beating consistency 3.5-4.5%, after beating degree, beating degree is respectively 40-50
0sR and 30-40
0sR.
The product major parameter that the present invention obtains is quantitative 70-80g/m
2, for improving paper feel, introduce the indignant thought of coefficient of friction, wherein, static friction coefficient is lower than 0.4, and dynamic mill coefficient of friction is lower than 0.35; Surface strength>=1.0m/s; Smoothness>=50s; Bulk>=1.35cm
3/ g; Paper color is white, whiteness 82-84%ISO; Longitudinal fracture length>=5000m.
Main innovate point of the present invention is: adopt part APMP, to make paper bulky more.For improving paper exquisiteness, the sodium carboxymethylcellulose (CMC) of 0.5-1.0kg/t slurry is added in NBKP and LBKP making beating respectively, and with reinforcing fibre wire-dividing broom purification, meanwhile, APMP beating degree is different from other producer's product domestic (generally not higher than 45
0sR), 53-57 is reached
0sR.For improving paper feel, top sizing adds 1-3kg/t paper lubricant, and introduces the indignant thought of coefficient of friction in Cultural Paper is produced, and wherein, static friction coefficient is lower than 0.4, and dynamic mill coefficient of friction is lower than 0.35, and this is domestic initiation.For making surface strength of paper meet 8 look business rotary printing requirements, add the polystyrene acrylate of 1-3kg/t paper at top sizing.
The high-grade raw white offset printing paper of the inventive method gained, papery is soft, low luster, and feel is good, and printing is simple, and third dimension is strong, and color printing color rendition degree is high, and picking speed is high, can as carrying forward the paper usings such as traditional Chinese culture book magazine.
