Abstract
The present invention relates to counterfeiting prevention coated white card paper and a production technique thereof. Cut and separated colored fiber is uniformly dispersed by water; the colored fiber is added into pulp in a bottom layer (or sandwich layer) pulping working section or a bottom layer (or sandwich layer) floating part and uniformly dispersed to obtain bottom layer (or sandwich layer) pulp; then, the bottom layer (or sandwich layer) pulp is conveyed to a paper making machine and manufactured together with surface layer pulp; therefore, counterfeiting prevention coated white card paper of which the bottom layer (or sandwich layer) is uniformly distributed with the colored fiber is formed. The colored fiber added into the bottom layer (or sandwich layer) pulp is uniformly distributed at the bottom layer (or sandwich layer) of the coated white card paper after being manufactured by the paper making machine; because of the diversity and distribution flexibility of the colored fiber, specific marks of the coated white card paper are easily formed till the coated white card paper has a counterfeiting prevention function. Compared with the past counterfeiting prevention technique, the counterfeiting prevention technique provided by the present invention has the advantages of little investment, easy popularization, etc.
Description
The present invention relates to a kind of anti-counterfeiting coating white card paper and production technology thereof.
The anti-counterfeiting technology of paper has at present: (1) metal anti-counterfeiting line, (2) fluorescent fiber, (3) watermark: (1) metal anti-counterfeiting line, spray into metal fibre in the papermaking forming part, and need to adopt special equipment, though antifalse effect is good, the equipment complexity, investment is big.(2) fluorescent fiber, in the paper pulp of papermaking, add the fluorescent fiber, be deposited in the fluorescent fiber of ply of paper inside, under the irradiation of ultraviolet light, can send versicolor fluorescent, it is false proof to be used for banknote abroad, fluorescent fiber price height, and product cost increases, and the fluorescent fibroid is crisp easily broken, the length inequality, and produce and use difficulty many, inconvenient operation.(3) watermark, this is a kind of paper false proof technology of early using, and in forming table special-purpose dandyprat is installed, and perhaps utilizes the rotary screen cage that is carved with pattern to produce watermark recovery, watermark recovery is more anti-to be made, and need increase equipment and carry out paper machine rebuilding, invests bigger.
Purpose of the present invention is to provide a kind of investment less, is applicable to wrapping anti-counterfeiting coating white card paper of general merchandise and production technology thereof, to reach false proof purpose.
The present invention realizes in the following manner: the bottom (or sandwich layer) at coated white cardboard is evenly distributed with colored fiber, this anti-counterfeiting coating white card paper is composited by the surface layer of general art post paperboard and the bottom (or sandwich layer) that has a colored fiber mark, thereby can obtain to have the product of three kinds of antifalse effects, a kind ofly be by surface layer, sandwich layer and have the coated white cardboard that the bottom of colored fiber sign is composited; Second kind is by surface layer, bottom and has the coated white cardboard that the sandwich layer of colored fiber is composited; The third is by surface layer and has the sandwich layer of colored fiber, the coated white cardboard that bottom is composited.
The surface layer slurry is general art post paperboard slurry, the addition of colored fiber is 0.005～0.25% of bottom (or sandwich layer) paper pulp weight, colored fiber can be selected animal and plant fiber, artificial synthetic fiber or blend fibre for use, and the length of colored fiber should be controlled homogeneous, and is bright in luster.
During production, the colored fiber water that whole cutting is chosen is uniformly dispersed, be chosen in bottom (or sandwich layer) beater floor or paper machine bottom (or sandwich layer) stream send portion that colored fiber is joined in the paper pulp, and it is uniformly dispersed, get (core) layer slurry on earth, deliver to the paper machine then and manufacture paper with pulp, thereby form the anti-counterfeiting coating white card paper that bottom (or sandwich layer) is evenly distributed with colored fiber with the surface layer slurry.
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is process chart of the present invention.
The embodiment of existing accompanying drawings this case:
As Fig. 1, add colored fiber (2) at the sandwich layer (1) of coated white cardboard, this anti-counterfeiting coating white card paper is composited by surface layer (3), the bottom (4) of general art post paperboard and the sandwich layer (1) that has colored fiber (a 2) mark.
As Fig. 2, during production, the colored fiber water that whole cutting is chosen is uniformly dispersed, be chosen in beater floor or paper machine bottom (or sandwich layer) stream send portion that colored fiber is joined in the paper pulp, specifically can be at the pulpboard hydrabrusher of beater floor, the stock tank that stirs, perhaps paper machine stream send the diluted mixture groove of portion, add in the fan pump, and it is uniformly dispersed, obtain bottom slurry (or sandwich layer slurry), deliver to paper machine and surface layer slurry then, sandwich layer slurry (or bottom slurry) is manufactured paper with pulp together, thereby forms the anti-counterfeiting coating white card paper that bottom (or sandwich layer) is evenly distributed with colored fiber.
Surface layer slurry, sandwich layer slurry (or bottom slurry) are general art post paperboard slurry, the addition of colored fiber is 0.005～0.25% of bottom (or sandwich layer) paper pulp weight, colored fiber can be selected animal and plant fiber, artificial synthetic fiber or blend fibre for use, the length of colored fiber should be controlled homogeneous, and is bright in luster.
Another more detailed embodiment of the present invention is:
1) product specification: 230 grams/square metre.Cardboard is made up of surface layer (3), sandwich layer (4), bottom (1).
2) kinds of fibers: red wool, blend fibre.
3) technological parameter: 1. colored fiber addition is 0.06% to the sandwich layer slurry, or ton paper colored fiber addition 0.03%;
2. fibre length is 0.5～5 millimeter.
4) mode of Jia Ruing and flow process:
1. add mode:
Colored fiber with whole cutting is chosen is uniformly dispersed by measuring the back water, joins in the pulpboard hydrabrusher of sandwich layer, is uniformly dispersed with the pulpboard size degradation.
2. production procedure: sandwich layer pulpboard and colored fiber join after hydrabrusher carries out pulping, delivering to the size degradation stock tank stirs, delivering to disc mill, blending chest, machine chest again handles, obtain the sandwich layer slurry, deliver to the paper machine through the paper machine stream portion of sending and manufacture paper with pulp, promptly obtain finished product with surface layer slurry, bottom slurry.
Characteristics of the present invention are: be added in the colored fiber of bottom slurry (or sandwich layer slurry), and after the paper machine is manufactured paper with pulp, Be evenly distributed on coated white cardboard bottom (or sandwich layer), because the diversity of colored fiber and the spirit of distribution Activity, thereby consist of easily its special mark, play false proof effect. False proof skill provided by the invention Art to compared with in the past anti-counterfeiting technology, has small investment, easily the advantage such as popularization.
