Description
Technical field
The invention belongs to pulp technology for making paper, be specifically related to a kind of micro-retractility printed form decorating base paper and preparation method thereof.
Background technology
Decorating base paper, in the process of printing and dipping glue, owing to moisture and glue are filled wherein, can cause that its transverse width has change in various degree.Current decorating base paper occurs that lateral expansion rate is excessive, causes that printing body paper of the draw above case can the phenomenons such as distortion, register trouble, pressing plate be asynchronous.
Existing decorating base paper transversely (is perpendicular to paper machine direction), takes the paper slip that length 1250mm width is 60mm, in thorough impregnation water after 5 minutes, measure paper slip length, current decorating base paper according to said method detect dipping after length at 1270-1285mm.Namely after horizontal hygroexpansivity (1270-1250)/1250*100=1.6% impregnates by that analogy, paper slip length becomes the paper of 1285mm, and its horizontal hygroexpansivity is 2.8%, and generally speaking the transversal stretching rate of current domestic decorating base paper is bigger than normal.
Summary of the invention
It is an object of the invention to provide a kind of micro-retractility printed form decorating base paper, in printing and dipping process, cross directional variations is less, is longitudinally not changed in, and can realize accurate overprinting, synchronize pressing plate；The preparation method that invention also provides micro-retractility printed form decorating base paper, scientific and reasonable, simple.
Micro-retractility printed form decorating base paper of the present invention, including the raw material of following weight percents:
Described bleached cotton starch, bleached softwood are starched, bleaching broad-leaved starches and wet strength agent is with over dry gauge.
Described bleached softwood slurry is bleached sulphate softwood pulp.
Described bleaching broad-leaved slurry is bleached sulphate yearning between lovers wood pulp.
Described wet strength agent composition is PAE, and usual concentration has 12.5% and 25% two kind.
Described mineral filler is one or more in titanium dioxide, Kaolin, Pulvis Talci, bentonite or kieselguhr.
The preparation method of micro-retractility printed form decorating base paper of the present invention, step is as follows:
(1) bleached cotton starch, bleached softwood slurry and bleaching broad-leaved slurry are separately added in the pulper equipped with 35-45 DEG C of pulping water abundant size degradation, standby in stock tank after controlling beating degree respectively to pump into mill after reaching 3.5-4.5% to 20-24,21-24,25-28 ° of SR, mass concentration；
(2) mineral filler being diluted to mass concentration is 65-72%, carries adding again and fill out in pond after stirring with high speed agitator；
(3) pump into add by stock tank serosity after mill and fill out pond, regulate to add and fill out the pH value of serosity in pond and, to 6.5-7.2, after stirring, add wet strength agent；
(4) interweave then through uniform and dehydration, dry, press polish, coil paper, cut, pack, and get final product after then above-mentioned modulated slurry being diluted, screens out foreign material.
Intertexture described in step (4) adopts multi cylinder line mesh production technology, is equipped with humidifier and soft press-polishing machine in process of production.
Jet-wire ratio can be regulated and controled by multi cylinder line mesh paper machine, and the abundant dehydration of fourdrinier wire, multi-cylinder ensure fully dry；Humidifier can ensure that into the moisture of paper；Soft press-polishing machine can ensure that the fine and smooth degree on paper industry surface.Wherein main control parameters: one, jet-wire ratio 1:1, fiber aspect to arrangement uniformly, is mutually wound around, decreases the cross-direction shrinkage in body paper dry run；Two, the stoving process of multi-cylinder, it is ensured that slowly dry, reduces the shrinkage factor in body paper dry run；High temperature cylinder temperature controls 120-150 degree, and the moisture after drying is≤2%, the abundant keratinization of body paper, reduces the ratio that body paper water suction profit rises；Three, after humidified device effect, body paper moisture reaches 5-7%, and the purpose of this technique had both improve the soft press-polishing machine ornamenting to decorating base paper surface, reduce again with print after the gap of body paper moisture, reduce the lateral expansion rate of body paper.
The raw material of micro-retractility printed form decorating base paper of the present invention includes: bleached cotton starch, bleached softwood slurry and bleaching broad-leaved slurry mixed slurry are main material；Account for the mineral filler of main material quality 20-45%；The quantification of 55-90g/m of this decorating base paper2, ash is 20-45%, and wet strength is 5-9N, and dry strength is 20-50N, and water absorption is 20-40mm/10min, and air permeability is 10-30s/100ml, horizontal hygroexpansivity≤1.6%, moisture 5-7%, the decorating base paper of seepage velocity≤5s.
It is 5:3:2 that described bleached cotton starch, bleached softwood slurry and bleaching broad-leaved starch preferred mass ratio.
The Substance of described decorating base paper is concentrated mainly on 60-85g/m2。
The performance parameter of decorating base paper of the present invention adopts instrument and condition shown in People's Republic of China (PRC) light industry standard GB/T24989-2010 to perform test.
The present invention compared with prior art, has the advantages that
Product provided by the invention is compared with existing product, in printing process, vertically and horizontally changes less, and clear patterns after printing keeps the shape.After downstream client impregnates, the change of paper transverse direction fabric width is little, and the decorative pattern on paper well can realize coincideing with the decorative pattern on steel plate when overlaying, and during pressing plate, decorative pattern not necessarily departs from.Existing decorating base paper is big because of lateral expansion, occurs off-set phenomenon with decorative pattern on steel plate.
