Description
Technical Field
The invention belongs to the technical field of production of gypsum board face protection paper, and particularly relates to colored anti-counterfeiting paper face protection paper for gypsum boards and a production method thereof.
Background
With the improvement of the living standard of people, the requirements of furniture decoration, commercial activities and the like on decorative materials are increasing, and brands with high-end quality are receiving more and more attention. High-end brands of products are not only favored by consumers, but are also the subject of major attacks by counterfeit products. The benefits of imitation of high-end branded products are far greater than the value of the products themselves. Therefore, more and more brands develop and use different anti-counterfeiting technologies to guarantee their own brand value. Anti-counterfeiting technology is a measure of prevention taken against an activity of imitation or copying that is aimed at fraud and not permitted by the owner.
The paper surface gypsum board facing paper is the two layers of paper which are covered on the two sides of the gypsum core and can be firmly adhered with the gypsum core material to protect the gypsum core when the paper surface gypsum board is produced. The building material made of the gypsum board has the characteristics of sound insulation, light weight, fire resistance, easy decoration and the like. An environment-friendly gypsum board facer disclosed in CN101718052a, for example, is made of a face paper web made of chemical pulp and an inner paper web made of waste pulp and fly ash fiber pulp. The anti-counterfeiting technology for the high-end paper-surface plasterboard is still a great difficulty in the industry, but the anti-counterfeiting of the plasterboard is generally realized by printing anti-counterfeiting marks after the plasterboard is formed at present, for example, the anti-counterfeiting tracing method and system of the plasterboard product disclosed in CN115330408A are realized by attaching RFID labels written with anti-counterfeiting information and anti-counterfeiting secret keys on the surface of the plasterboard product; for example, CN115285484a discloses a gypsum board anti-counterfeiting chip mounting device, in which an anti-counterfeiting chip is also mounted; or manufacturing a storage groove in advance in the process of producing the gypsum board, and clamping the identification box with the anti-counterfeiting function on the groove; or through spouting sign indicating number or intelligent coding on the gypsum board surface, but all need operate on the gypsum board by above-mentioned measure, but in actual production, gypsum board production is big, and the complex process of fluting in the gypsum board is inside seriously influences production volume and production quality, and in surface labelling or spouting sign indicating number, drops easily in transportation or sales process, wearing and tearing. Thus, the anti-counterfeiting of gypsum boards is always a difficult point to be solved by the industry.
Although there are also cases where falsification is prevented by using fibers and pulp, there are the following problems as a face-care paper for gypsum board:
1. when paper is manufactured, colored fibers or colored small pieces (dots) such as red and blue are doped into paper pulp, and are fixed in the middle of the paper after the paper is formed, and red and blue fiber yarns and colored dots colored fibers doped into the paper pulp can be seen on the paper surface by naked eyes.
2. Before the paper is unshaped, colorless fluorescent fibers with fluorescent properties are scattered on the surface of the paper, and fluorescent reflection is carried out under ultraviolet irradiation, so that the paper is provided with colored fibers different from the paper, the colorless fluorescent fibers can be displayed under the ultraviolet irradiation, the colors of the colorless fluorescent fibers are red, blue, orange and the like, the shapes of the colorless fluorescent fibers can be thick or thin, the lengths of the colorless fluorescent fibers can be long or short, and the fibers and color points are generally randomly distributed, so that the color points are slightly different from each other. However, such fluorescent anti-counterfeiting fibers are generally carcinogenic and are greatly limited in application in the fields of food packaging and furniture decoration base paper.
3. There are also metal foils, plastic round chips, which are incorporated into paper pulp to prevent counterfeiting, such as paper money issued in italy, with a metal foil sandwiched between them, which is invisible to the naked eye, and which can make a sound when inspected with a special identifier. The anti-counterfeiting method has high anti-counterfeiting cost, is only applied to the fields of currency, commemorative coins and the like in a small amount, and is inconvenient to realize in the gypsum board facing paper anti-counterfeiting technology.
Therefore, the gypsum board has a great technical difficulty in realizing the anti-counterfeiting of the gypsum board through the paper surface gypsum board protection paper.
