Description

Technical Field

[0001] This utility model relates to the field of inkjet printing paper technology, specifically to a special paper for inkjet printing. Background Technology

[0002] In the printing and packaging industry, digital inkjet technology is gaining popularity among professionals. The advantages of digital inkjet printing on packaging products are: it eliminates the need for plate making and has no limitations on print runs, truly enabling single-sheet printing, making it particularly suitable for small-batch, personalized orders. During digital inkjet printing, the printhead does not contact the substrate; ink droplets are transferred to the substrate using different inkjet methods. No pressure is required, making digital printing especially advantageous for uneven surfaces like packaging paper.

[0003] Currently, general digital printing paper, also known as traditional printing paper, mainly includes coated white cardboard and coated white-faced kraft paper. Its structure is relatively simple and it does not have waterproof function, making it easy to be soaked and stained by water during transportation and delivery. After getting damp, the printed text will quickly fade or disappear, and the paper will wrinkle. Since people often need to use this printing paper in damp places, the lack of waterproof function of such printing paper brings a lot of inconvenience to actual use. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 2 As shown, the present invention provides a special paper for inkjet printing, comprising a base paper 1, a first toughening layer 2 bonded to the bottom of the base paper 1, a second toughening layer 3 bonded to the bottom of the first toughening layer 2, a buffer layer 4 bonded to the bottom of the second toughening layer 3, an anti-penetration layer 5 bonded to the bottom of the buffer layer 4, an auxiliary pulp layer 6 bonded to the top of the base paper 1, an ink-fixing layer 7 bonded to the top of the auxiliary pulp layer 6, and an ink-absorbing layer 8 bonded to the top of the ink-fixing layer 7.

[0018] refer to Figure 1The bottom of the anti-permeability layer 5 is bonded with a wear-resistant paper shell 9, and the top of the wear-resistant paper shell 9 extends to the ink-absorbing layer 8 and is used in conjunction with it. The wear-resistant paper shell 9 is made of natural plant wax and cellulose and other raw materials.

[0019] As a technical optimization of this utility model, the wear-resistant paper shell 9 is made of raw materials such as natural plant wax and cellulose, which gives the wear-resistant paper shell 9 good waterproof and wear-resistant properties, thereby providing protection for each layer and preventing the wear of the anti-permeability layer 5 during the use of the inkjet printing special paper, making the anti-permeability effect of the anti-permeability layer 5 more durable.

[0020] refer to Figure 1 and Figure 2 The bottom of the wear-resistant paper shell 9 is provided with an adhesive layer 10, and the bottom of the adhesive layer 10 is provided with release paper 11.

[0021] As a technical optimization of this utility model, the adhesive layer 10 and the release paper 11 make it easier to quickly adhere the inkjet printing paper to the designated position, thus making it more convenient for users.

[0022] refer to Figure 1 The surface of the first toughening layer 2 has several transverse holes, which are evenly arranged in a transverse direction, and transverse ribs 12 are fixedly connected inside the transverse holes.

[0023] As a technical optimization of this utility model, the longitudinal tensile strength of the inkjet printing paper can be improved by setting the transverse holes and transverse ribs 12, thereby improving the strength of the inkjet printing paper in use.

[0024] refer to Figure 1 The surface of the second toughening layer 3 has several longitudinal holes, which are evenly arranged in the transverse direction, and longitudinal ribs 13 are fixedly connected inside the longitudinal holes.

[0025] As a technical optimization of this utility model, the longitudinal holes and longitudinal ribs 13 can improve the lateral tensile strength of the inkjet printing paper, thereby further improving the strength of the inkjet printing paper.

[0026] refer to Figure 1The base paper 1 is made of wood pulp paper, the first toughening layer 2 is made of nano-glass fiber, the second toughening layer 3 is made of natural fiber, the buffer layer 4 is made of straw fiber paper, the anti-permeability layer 5 is made of PET film, the auxiliary pulp layer 6 is made of fiber paper, the ink-fixing layer 7 and the ink-absorbing layer 8 are existing technologies, and their materials are calcium carbonate, modified calcined kaolin and related auxiliary materials. The principle of the ink-fixing layer and the ink-absorbing layer are similar to those mentioned in the Chinese patent application No. 202410814088.4, which discloses a special paper for digital inkjet printing for printing and packaging and its preparation method. The effect is the same, and it is an existing disclosed technology in this field. It will not be elaborated here. The horizontal ribs 12 and the vertical ribs 13 are made of polypropylene fiber.

[0027] As a technical optimization of this utility model, the base paper 1 made of wood pulp paper has better flexibility and tensile strength, is not easily damaged during use, and has better environmental protection. The first toughening layer 2 is made of nano glass fiber material. Nano glass fiber is finer than ordinary glass fiber, but it has higher strength and impact resistance and is lightweight. The second toughening layer 3 is made of natural fiber material. Natural fiber has good wear resistance. Because its fibers have high strength and toughness, they are not easily damaged or worn under external forces such as friction and pulling, thus ensuring a longer service life. The cushioning layer 4 of straw fiber paper has good cushioning properties, and its environmental protection characteristics also give it an advantage in sustainable packaging. The anti-permeability layer 5 made of PET film has good heat and cold resistance, good chemical stability, and excellent anti-permeability function. The ink-fixing layer 7, made of calcium carbonate, modified calcined kaolin, and related auxiliary materials, improves porosity and its bonding performance with other raw materials, while also improving its interaction with water-based inks, thereby improving its adsorption and fixation of water-based inks. The transverse ribs 12 and longitudinal ribs 13 made of polypropylene fibers strengthen the paper's structure and tensile strength.

[0028] The working principle and usage process of this utility model are as follows: When using this inkjet printing paper, the ink-absorbing layer 8 is used to absorb ink, and then the ink-fixing layer 7 prevents the ink from flowing and fixes it on the auxiliary pulp layer 6, preventing the ink from spreading and affecting the printing quality. The buffer layer 4 makes the inkjet printing paper more gentle under the machine force during the printing operation. Then, the adhesive layer 10 can stick the printed inkjet printing paper to the designated position. At this time, the anti-permeability layer 5 can prevent water from penetrating into the base paper 1. The wear-resistant paper shell 9 not only provides protection for each layer, but also prevents the anti-permeability layer 5 from being worn during the use of the inkjet printing paper, making the anti-permeability effect of the anti-permeability layer 5 more durable. This makes the inkjet printing paper waterproof and has good tear resistance, preventing the paper from wrinkling and cracking, thereby effectively extending the service life of the inkjet printing paper.
