Description
Technical field
The present invention relates to field of anti-counterfeit technology, be specifically related to a kind of Novel anti-counterfeit paper.
Background technology
Rare earth oxide refers to that period of element atom ordinal number is 15 kinds of lanthanide oxides of 57 to 71, and the oxide of the scandium similar to lanthanide series chemical property (Sc) and yttrium (Y) totally 17 kinds of elements.Rare earth element is obtained in fields such as oil, chemical industry, metallurgy, weaving, pottery, glass, permanent-magnet materials and applies widely.Rare earth element can absorb to the property selected visible ray makes it send different light, due to the electron energy level of rare earth element and spectral line more rich and varied than other element, they, having absorption or emission phenomena from ultraviolet light, visible ray to infrared light district, are therefore extraordinary coloring matters.
One by name " cheque paper ", publication number is 1102865A, publication date be 19950524 patent of invention disclose a kind of cheque paper, this cheque paper has the security protection line in the embedding paper can directly seen in some region.The width of security protection line is greater than 2 millimeters.Cheque paper comprises at least two-layer paper web produced by different paper machines.The surface embedding the security protection line of the first ply of paper has opening or sunk part, partly can see guard wire in both sides by them.Cover the first ply of paper with at least one deck second ply of paper, and make them be firmly connected to each other, the thickness of the second ply of paper accounts for 10 ~ 50% best 20% of cheque paper gross thickness.Use wide especially and there is the security protection line of certain optical effect, just can improve the anti-counterfeit capability of cheque paper.This cheque paper complex structure, and security protection line easily drops.
Summary of the invention
The object of the invention is to solve the ineffective security existed in the anti-counterfeiting technology of current paper-based article, the problem such as poor for applicability, fabrication schedule is complicated, a kind of Novel anti-counterfeit paper is provided, this Novel anti-counterfeit paper has that antifalse effect is excellent, applicability good, and it is good with the conjugation of paper-based article, in manufacturing process, technique is simple.
In order to reach foregoing invention object, the present invention by the following technical solutions:
A kind of Novel anti-counterfeit paper, anti-counterfeit paint is adopted to apply one deck false proof layer at paper surface, described anti-counterfeit paint is made up of following component by weight percentage: precipitated calcium carbonate 20-40%, kaolin 15-35%, water repellent agent 1-5%, carboxylic styrene butadiene latex 10-21%, dispersant 3-5%, rare earth anti-false fiber 2-5%, surplus is water.
The present invention adopts the fibre false-proof layer prepared containing rare earth oxide in paper surface coating, thus realizes the antifalse effect of paper.Rare earth element has Selective absorber to visible ray, thus makes it send the different light of color.Due to the electron energy level of rare earth element and spectral line more rich and varied than other element, they, having absorption or emission phenomena from ultraviolet light, visible ray to infrared light district, are therefore extraordinary coloring matters.Adopt anti-false fiber prepared by rare earth, and utilize the optical property of rare earth, good antifalse effect can be reached.By being coated on paper surface with rare earth anti-false fiber, there is the simple feature of technique.The effect of latex, add rare earth anti-false fiber and anti-counterfeit paint at paper surface in conjunction with firmness.The infiltration of water repellent agent to much liquid has resistivity, can form a kind of well water resistant lotus leaf effect, not change the porosity of paper, pliability, gas permeability, outward appearance and wet strength simultaneously.
As preferably, described water repellent agent is polyamide carbamide resin or melamine resin.Paper can be made to have resistivity to glassware for drinking water, can form a kind of well water resistant lotus leaf effect, as preferably, described dispersant is triethyl group hexyl phosphoric acid, methyl anyl alcohol or guar gum.Dispersant is convenient to being uniformly dispersed of each component.
As preferably, the thickness of described false proof layer is 35-55 μm.False proof layer is too thin, and anti-false fiber is bonding insecure, and false proof layer thickness is too large, can affect the performance of paper.As preferably, described anti-counterfeit paint is prepared from by following steps: by each component of anti-counterfeit paint by weight percentage mix and obtain anti-counterfeit paint.
Owing to adopting technique scheme, the invention has the beneficial effects as follows: (1) preparation technology is simple; (2) false proof layer is combined with paper firmly; (3) light sensitivity that possesses of rare earth oxide characteristic is good, and susceptibility is high.
