Definitions
- the invention relates to the pulp and paper industry, in particular, to the production of paper for the manufacture of banknotes, checks, certificates, bills, passports, identification cards, coupons for gasoline, tickets for entertainment events and other documents requiring protection from counterfeiting.
- JP2-127599, 05.16.1990 A known method for producing a watermark simulation on paper, in which a liquid composition obtained by mixing paraffin, oil and saturated fatty acid with a solution of resin in an organic solvent is applied to paper by printing.
- a method for producing a watermark simulation, according to which a composition containing hexamethoxymethylmelamine, a curing reagent and a colorless polar solvent is applied to sheets of paper.
- thermosetting resin it is proposed to use, including epoxy resins. In this case, after evaporation of the solvent and curing of the thermosetting resin on the paper, transparent areas that simulate a watermark are formed.
- the problem solved by the invention is the receipt on paper of transparent areas without the formation on the paper surface of solid films that impede the subsequent sealing process.
- the technical result is achieved by the fact that in the method of manufacturing paper with transparent sections of a certain shape, in which sections of paper are locally impregnated with a solution of compounds with epoxy groups in the presence of a curing agent, according to the invention, glycidyl ethers of mono- and polyhydric alcohols are used as compounds with epoxy groups,
- n 1-3
- R is the residue of a mono- or polyhydric alcohol, and characterized by a dynamic viscosity at a temperature of 25 ° C of not more than 150 mPas
- glycidyl ethers of mono- and polyhydric alcohols are dissolved in organic solvent in a mass ratio of from 30% to 90%.
- solutions of glycidyl ethers of mono- and polyhydric alcohols in an organic solvent are applied by printing to sections of paper with a thickness of not more than 80 ⁇ m obtained on paper during its casting process on a paper machine.
- the transparent areas are in the form of geometric shapes, symbols, letters or numbers visible in transmitted light
- printed images are applied to paper with transparent portions.
- printed images are preliminarily applied to the paper, and then the paper is impregnated to obtain transparent areas.
- glycidyl esters of mono- and polyhydric alcohols used in the method of the invention monoglycidyl ether, n-butanol, butyl cellosolve monoglycidyl ether, monoglycidyl ether, 2- ethylhexanol, the diglycidyl ether of diethylene glycol, polyoxypropylene glycol diglycidyl ether, polyoxypropylene triglycidyl ether, diglycidyl ether of 1, 4-butanediol diglycidyl neopentyl glycol ether, triglycidyl ether trimethylolpropane and others.
- these compounds can be used either individually or as a mixture of two or more compounds.
- These compounds are colorless or light yellow low viscosity liquids that contain epoxy groups with a mass fraction of from 7.5% to 30% and are well combined with all known hardeners of epoxy resins.
- aliphatic or aromatic polyamines, acid anhydrides, Lewis acids, etc. can be used to cure them.
- solvents for these compounds isopropyl alcohol, ethyl acetate, propyl acetate, methyl ethyl ketone, methyl isobutyl ketone, dimethylformamide, as well as mixtures thereof, etc. are used.
- the dynamic viscosity of glycidyl ethers of mono- and polyhydric alcohols should be at a temperature of 25 ° C not more than 150 MPa s, or, even more preferably, not more than 50 MPa. If their dynamic viscosity at a temperature of 25 ° C exceeds 150 MPa s, then when the product is dissolved in an organic solvent in a mass ratio of more than 50%, there are problems associated with the deterioration of the penetration of the resulting solution into the paper structure.
- solutions of glycidyl ethers of mono- and polyhydric alcohols in organic solvents are carried out by printing methods.
- these solutions can be applied to paper using anilox rolls with a lineature of 60-120 lines / cm ⁇ and ink intensity of 10-24 cm ⁇ / m ⁇ .
- the viscosity of the solutions measured on a funnel with a hole diameter of 4 mm, in this case should be in the range of 10-35 seconds, or, even more preferably, in the range of 10-15 seconds.
- solutions can be applied to specified areas at the same time. on both sides of the paper.
- the formation of transparent areas after applying solutions to the paper by printing methods is conventionally carried out in two stages. At the first, shortest stage, the solvent evaporates and the solution is absorbed into the paper. To speed up the process at this stage, it is advisable to naphtha paper to a temperature of 85-140 ° C. In the second stage, which is the longest in time and fully completed already on the roll or in the foot, the solution absorbed into the paper undergoes final curing. This step usually lasts for 3-4 days after applying the solution to the paper.
- Paper is made on a round-mesh or flat-mesh paper machine. It may contain wood, cotton cellulose, as well as synthetic fibers (nylon, polyester). In addition, the paper may contain fillers (titanium dioxide), additives to increase the strength of the paper in the dry and wet state (sodium salt of carboxymethyl cellulose, polyamide (amine) epichlorohydrin resin), substances for sizing paper in bulk (alkyl ketene dimers), dyes (direct, acidic). In the manufacturing process, the paper is glued from the surface with an aqueous solution of polyvinyl alcohol, and also, which is less preferred aqueous dispersions of polyurethane, acrylate or styrene acrylate. If necessary, the paper may contain watermarks, fibers, threads and other security features.
- fillers titanium dioxide
- additives to increase the strength of the paper in the dry and wet state sodium salt of carboxymethyl cellulose, polyamide (amine) epichlorohydrin resin
- Solutions are preferably applied to sections of paper with a thickness of not more than 80 microns. This allows you to get on the paper after absorption of the solution and curing transparent areas with high transparency.
- paper used to make banknotes with a weight of 90 g / m2
- portions of a given shape and size having a smaller thickness compared to the thickness of the paper can be formed during the outflow of the paper web.
- you can use an eing or plate cylinder with waterproof elements (filigree), which have the size and shape of these sections, during the paper casting process on a paper machine.
- the thickness of the paper in this case, can be changed by rasterizing and changing the thickness of these waterproof elements.
- sections of smaller thickness can be formed on paper using the method described in US6402888, 06/11/2002.
- Transparent areas obtained by printing solutions onto paper must have the shape and size required by the product design. For example, they may be located on a piece of paper symmetrically aligned fragments of a watermark (RU2475578, 02.20.2013). And in this case, they are given the shape and size of the combined fragments of the watermark.
- the transparent areas can be in the form of a square, circle, ellipse, etc.
- the transparent areas can be sealed using conventional printing methods used for the manufacture of valuable documents, including banknotes. For example, in transparent areas you can print by offset, metallographic, high or screen printing methods. In addition, you can first carry out the sealing of specified sections of paper by the above printing methods, and then apply a solution to them in order to obtain transparent areas.
- the transparency level of the transparent areas was evaluated by measuring the optical density of the paper using a ⁇ -Rite transparency densitometer. At the same time, a decrease in optical density signified an increase in paper transparency.
- a banknote paper weighing 90 g / m2 was made using a well-known technology on a round-mesh paper machine using a plate cylinder with watertight elements fixed to the grid in certain positions.
- the paper was glued in an impregnation bath with a 4% aqueous solution of PVA. In this case, it is symmetrical to the location of the waterproof elements on the grid, sections were formed on paper whose thickness was less than the thickness of the paper (PO microns.) And varied in the range of 60-96 microns.
- Triglycidyl ether 35 hours polyoxypropylene triol
- the solution was applied both to sections of paper with a thickness of ON microns, and to thinner sections formed on paper symmetrically to the arrangement of waterproof elements. After drying and complete curing of the solution (after 72 hours), in the places where the solution was applied to the paper, transparent portions visible to the lumen were formed.
- diethylene glycol diglycidyl ether (dynamic viscosity, 25 ° C - 38 MPa) was used in the solution instead of triglycidyl ether of polyoxypropylene triol.
- butyl cellosolve monoglycidyl ether (dynamic viscosity, 25 ° C - 6 MPa) was used in the solution.
- Polyoxypropylene triol triglycidyl ether 25 h (dynamic viscosity, 25 ° ⁇ - 115 MPa)
- Polyoxypropylene triol triglycidyl ether 25 h (dynamic viscosity, 25 "C - 115 MPa s)
