Abstract
The invention provides a preparation method of locally strengthened paper and locally strengthened paper prepared by the method; the locally strengthened paper is manufactured by a net cage paper making machine; the preparation method comprises the following steps: manufacturing a first wet paper sheet with anti-counterfeiting area on one net cage of the net cage paper making machine; spraying and manufacturing a second wet paper sheet with hollowed area on net cage of the other net cage paper making machine; synchronously controlling the first wet paper sheet and the second wet paper sheet to compound the hollowed area and anti-counterfeiting area to obtain compound wet paper sheet; obtaining the locally strengthened paper after carrying out subsequent handling to the compound wet paper sheet. The contrast degree of watermark or definition and three-dimensional effect of watermark is more obvious, and the anti-counterfeiting performance of the paper thereof can be increased so as to be easily recognized. The compound strengthened area of the locally strengthened paper of the invention is hard to be fluffed and tear while the fibre is hard to be loosed, wherein the density of the strengthened area is larger than that of non-compound area. The deflection of the compound strengthened area is greater than that of the non-compound area. The locally strengthened paper has the unique feel and the increased negotiability, improves the anti-counterfeiting performance and prolongs the service life of the paper.
Description
Technical field
The present invention relates to a kind of local stiffening paper and manufacturing approach thereof.This technology belongs to papermaking and field of anti-counterfeit technology.
Background technology
Chinese patent CN200610020756.8 has disclosed a kind of method that the strip-like features thing is set in paper; Its preparation method comprises that successively the upper strata l Water Paper page or leaf of manufacturing paper with pulp, the controlled lower floor's l Water Paper page or leaf that adheres to, manufactures paper with pulp of characteristic body, l Water Paper page or leaf are combined into the paper step; This method realizes the dispensing of characteristic body in paper-making process, can control the position and the quantity of characteristic body dispensing.
Korean Patent KR100648430 discloses a kind of in order to prolong the currency of cheque paper, improves the method for bank-note paper durability.This patent has been introduced in paper pulp and have been added a kind of l Water Paper function enhancers carboxymethyl cellulose (CMC) or guar gum is produced a kind of body paper; This body paper is by comprising polyvinyl alcohol; Modified aminoresin and catalyst are after interior solution surface is handled; Handle the back drying by hardening solution again, thereby reach the purpose of improving the bank-note paper performance, prolonging its circulation life-span.
The false proof report of China, 2007,1; 26～35 have described the E series new edition sterling of present circulation; Its paper adopts special-purpose paper, and mainly being manufactured paper with pulp by long cotton, flax fibre forms, and papery is tough and tensile, deflection and tear resistance are good; Long-term circulation fiber is not loose, phozy, do not rupture, and strengthened the anti-trafficability performance of bank-note paper.
Though above patent is different with the method for reporting the enhancing cheque paper anti-counterfeiting performance of being introduced, anti-circulation; But purpose all is for the antifalsification that improves cheque paper, prolongs its anti-trafficability performance, and they are mainly from the raw material of bank-note paper, the anti-circulation that the chemical assistant aspect improves cheque paper.
In sum, this area lacks a kind of antifalsification that improves cheque paper, prolongs the local stiffening paper of its anti-trafficability performance.Therefore, this area presses for exploitation local stiffening paper, and its composite consolidation zone is not easy to fluffing, is difficult for tearing, fiber is not easy loosely, and wherein the density of reinforcing area is greater than non-recombination region; The deflection in composite consolidation zone is greater than non-recombination region, and the paper through local stiffening has unique feel, anti-circulation to strengthen, anti-counterfeiting performance improves, prolonged paper service life.

The present invention provides a kind of preferred specific embodiment in addition, and the l Water Paper page or leaf on two cylinder moulds carries out independence by different stock mixing systems, approach system respectively and supplies slurry, and one of them cylinder mould is through Specialty Design, processing, contain can drainage the zone and the zone of drainage not.After paper fibre is pulled an oar through jordan; Be pumped to centrifuging distributor 3 through passing on; Again through short former 2 whitewashing online; Form the slurry layer in zone that can drainage, zone that can not drainage forms blank (hollow out) zone, manufactures paper with pulp in 1. number rotary screen cage 4 online and contains blank (hollow out) l Water Paper page or leaf; The manufacture paper with pulp l Water Paper page or leaf or manufacture paper with pulp of a kind of false proof means in the watermark that contains the fixed position, safety line, anti-false fiber, the false proof tablet of another cylinder mould contains in watermark, safety line, anti-false fiber, the false proof tablet l Water Paper page or leaf of two kinds or two or more false proof means; Two l Water Paper pages or leaves carry out compound at 2. number rotary screen cage 6 places, then successively through squeezing, surface treatment, drying, operation such as curl, print, cut and handle back gained local stiffening paper, it quantitatively is 70-170g/m
2The local stiffening paper has realized that the local location physical index improves, anti-circulation strengthens, security feature strengthens, masses are easy to identification, forges difficulty.
The present invention also provides a kind of preferred specific embodiment, and what be characterized in containing the regional l Water Paper page or leaf of blank (hollow out) quantitatively is to realize through the thickness of regulating the slurry layer that short former whitewashing online become.Can not the regional figure of drainage be the combination of a kind of or more than one patterns in rectangle, ellipse, circle, round rectangle, polygon and the ramage, the page quantification that blank (hollow out) is arranged be 15～50g/m
2
The local stiffening paper that obtains
The invention has the advantages that: can realize that the local physical strength index of paper is higher than the physical strength index of other positions.
In a specific embodiment of the present invention, the said second l Water Paper page or leaf quantitatively be 15～50g/m
2, the Substance that two l Water Paper pages or leaves are composited is 70～170g/m
2
The inventor finds that the contrast of false proof zone of the present invention such as watermark or watermark definition and stereoeffect are more obvious, and the anti-counterfeiting performance of its paper improves, and masses discern easily.And the density that the composite consolidation zone is not easy to fluff, be difficult for tearing, fiber is not easy loose, reinforcing area is greater than non-recombination region; The deflection in composite consolidation zone is greater than non-recombination region;
Bad phenomenon such as breach, burr, arrisdefect in various degree in the process of circulation, occur around the paper by the produced cheque paper of present technology, shortened the service life of cheque paper.The present invention can effectively solve cheque paper and bad phenomenon such as breach, burr, scarce limit in the process of circulation, occur, can strengthen the anti-circulation of paper, has prolonged the service life of cheque paper.
Other aspects of the present invention are because the disclosure of this paper is conspicuous to those skilled in the art.
