Description
Technical Field
The invention belongs to the technical field of papermaking, and particularly relates to a preparation method of a three-dimensional anti-counterfeiting white cardboard.
Background
In order to prevent the products of each commodity manufacturer from being counterfeited, the commodity manufacturers mostly adopt anti-counterfeiting paper to package the produced commodities for anti-counterfeiting, the anti-counterfeiting paper also helps consumers to rapidly identify the authenticity of the commodities in each industry, consumers are protected from benefiting, and simultaneously enterprise users are helped to strike counterfeit products, batch counterfeiting is stopped, enterprise brands are protected, enterprise images are maintained, and economic loss is avoided. At present, the technologies applied to the production of anti-counterfeiting paper mainly comprise a printing anti-counterfeiting technology and an in-pulp anti-counterfeiting technology.
In the printing anti-counterfeiting technology, the ink is an important component for anti-counterfeiting. The anti-counterfeiting ink can be roughly divided into fluorescent ink, magnetic ink and the like, and the ink attached to the surface of a substrate has the greatest defect that the effect of the ink is damaged by various physical and chemical actions on the surface, so that certain decline is generated in the circulation process.
In the in-pulp anti-counterfeiting technology, anti-counterfeiting marks are added into a paper core layer, so that the paper has an anti-counterfeiting function. The traditional paper machine with the mixed addition process in the pulp has a long production flow, the anti-counterfeiting material can stay for more than 10 hours or even longer in the processes of fine pulp refining, blending and pulp storage, the temperature of the general pulp can reach about 65 ℃ at most through the processes of cooking and pulping, and the physical properties of the anti-counterfeiting identification material can be changed due to long-time high temperature and water immersion, so that the using effect is reduced, and the application effect is finally influenced. Therefore, in order to make the anti-counterfeit mark exhibit the expected effect, the equipment needs to be modified or a special anti-counterfeit material is added, which results in increased cost.
In summary, a new method for preparing anti-counterfeit paper needs to be developed to solve the problem of the conventional anti-counterfeit mark adding method in the existing in-pulp anti-counterfeit technology that the anti-counterfeit effect is reduced.
Disclosure of Invention

(1) respectively preparing surface paper layer slurry, core paper layer slurry and base paper layer slurry;
(2) loading the anti-counterfeiting mark on a carrier to obtain an anti-counterfeiting layer;
(3) respectively filtering the surface paper layer slurry, the core paper layer slurry and the bottom paper layer slurry prepared in the step (1), adding the anti-counterfeiting layer obtained in the step (2) into the core paper layer slurry, and compounding the surface paper layer slurry, the core paper layer slurry and the bottom paper layer slurry to obtain a composite slurry layer with the thickness of 150-;
(4) after the composite pulp layer is formed by paper sheets, performing surface sizing after squeezing and primary drying, and then performing coating and secondary drying, reeling and packaging to obtain the three-dimensional anti-counterfeiting white cardboard;
the carrier is glutinous rice paper.
Preferably, the preparation method further comprises adding a dye to the core paper layer slurry and the face paper layer slurry before the step (3).
Further preferably, the method for adding the dye is as follows: and (3) pumping the slurry into a high-level box from a slurry forming pool, pumping the dye into the high-level box by using a gas film pump, mixing, then feeding into a slurry inlet box, and then surfing the net.
Preferably, the anti-counterfeiting marks are orderly and continuously arranged in the paper in a linear strip shape or a curve shape.
Preferably, the anti-counterfeiting marks are orderly and discontinuously arranged in the paper in a linear strip shape or a curve shape, and the discontinuous distribution means that each anti-counterfeiting unit is scattered in a dot shape or a discontinuous distribution.
Preferably, the anti-counterfeiting marks are randomly arranged in the paper.
Preferably, the anti-counterfeiting mark is made of one or a combination of a plurality of magnetic materials, pressure-sensitive materials, photoluminescent materials and biological anti-counterfeiting information materials.
Further preferably, the photoluminescent material is a quantum dot material, a fluorescent material, a temperature-change material or an infrared material.
Further preferably, the biological anti-counterfeiting information material is antigen antibody or DNA.
Preferably, the thickness of the glutinous rice paper is 0.02-0.5 mm.
In the step (1), the preparation methods of the surface paper layer slurry, the core paper layer slurry and the surface paper layer slurry are as follows: pulping the pulp board after being pulped by a hydrapulper, directly pulping if self-pulping, then batching, and making the pulp by a paper feeder.
The glutinous rice paper is inner layer packing paper applied to candies, cakes or medicines and the like in the market, is mainly formed by mixing starch, gelatin and a small amount of lecithin, casting into a film and drying, has good flexibility, isolation and lubricity, is melted when meeting water, and ensures the integrity of a wrapped object without influencing subsequent treatment if applied to the paper. In view of various characteristics of the glutinous rice paper, the glutinous rice paper is used as a carrier of the anti-counterfeiting mark, and the anti-counterfeiting mark is arranged in the paper sheet by controlling the melting speed and the melting temperature of the glutinous rice paper, so that a three-dimensional anti-counterfeiting effect is generated, and the non-replicability of anti-counterfeiting is ensured.
In the step (2), the anti-counterfeiting marks are arranged on the glutinous rice paper according to a certain rule, then the anti-counterfeiting marks are irregularly and three-dimensionally arranged on the paper sheet core layer by controlling external conditions, the glutinous rice paper can be melted when meeting water, the temperature can influence the melting speed of the glutinous rice paper, the anti-counterfeiting marks are left on the paper sheet core layer after the glutinous rice paper is melted, after the following three layers are compounded, the physical properties of the paper sheet cannot be influenced through the subsequent treatments such as squeezing, the anti-counterfeiting marks can be perfectly combined with the paper sheet, and the phenomena such as layering cannot occur.
According to the invention, by adopting the glutinous rice paper which is degradable by biomass as a carrier, the anti-counterfeiting marks are arranged in the paper page in a three-dimensional and irregular manner by adjusting the melting speed and the temperature, under the condition of not influencing each physical index of the paper, the irreproducibility of the anti-counterfeiting technology is ensured, and the anti-counterfeiting cost and the uncontrollable property of the anti-counterfeiting marks are reduced.
The temperature is controlled mainly to lead the melting speed of the glutinous rice paper to be different, thereby leading the glutinous rice paper to show different forms in the pulp layer and forming the three-dimensional anti-counterfeiting effect. The glutinous rice paper loaded with the anti-counterfeiting mark can be subjected to different water vapor forces when being added into the pulp layer, so that the directions of the glutinous rice paper loaded with the anti-counterfeiting mark are different when the glutinous rice paper reaches the pulp layer, and the expressed forms are different, thereby forming an irregular anti-counterfeiting mark.
Because the glutinous rice paper is used as a carrier and is melted when meeting water, the glutinous rice paper can be influenced by the airflow of water vapor after being added to the net in the pulp of the core layer, can not be completely and completely added into the core layer without any denaturation, no available adding equipment is available on the market, and the equipment needs to be researched and developed automatically. The specific process of this part of the experiment is as follows:
starch emulsification: soaking starch passing through 100 mesh sieve in 50-55 deg.C water, and emulsifying under stirring, wherein the water amount is 2.5-3 times of starch amount, and the emulsified concentration of starch is 15-17 Baume degree. And (4) passing the starch through a 100-mesh screen after the starch is completely emulsified for later use.
Preparing a phospholipid emulsion: heating 1-2% caustic soda solution to 85-100 deg.C, adding phospholipid (the amount of caustic soda is 0.8-1.8% of phospholipid) under stirring, naturally cooling to 30-40 deg.C after the phospholipid is completely melted, sieving with 100 mesh sieve, and making into 1-2% phospholipid emulsion with pH of 8-9.
Paste mixing: heating the starch emulsion to 50 ℃, adding a proper amount of phospholipid emulsion under the stirring state, continuously heating to 90 ℃, and keeping the temperature for 1-2 hours to obtain the starch paste. The stirring speed is 40 r/min, and the concentration is 7-8%.
After the starch paste is cooled to room temperature, adding a proper amount of rosin or AKD under the stirring state, and stirring for 2-3 hours to obtain a final product.
Film making: because the laboratory does not have professional film making equipment, the laboratory adopts a simple glass device to carry out film forming treatment, and the modified glutinous rice paper with the thickness of 1-5mm is obtained and can be used for in-pulp anti-counterfeiting.
The invention has the advantages of
