Description

Technical Field

[0001] This utility model belongs to the field of digital printing paper technology, and in particular relates to a quick-drying inkjet digital printing paper. Background Technology

[0002] Digital printing is a new printing technology that utilizes a prepress system to directly transmit graphic information via a network to a digital printing press for printing. A digital printing system mainly consists of a prepress system and a digital printing press; some systems also include binding and cutting equipment. Its working principle is as follows: The operator outputs the original artwork (digital graphic information), digital information from digital media, or network digital files received from the network system to a computer. On the computer, the operator creates, modifies, and arranges the artwork to the client's satisfaction, resulting in digital information. After RIP processing, the corresponding monochrome pixel digital signals are transmitted to the laser controller, which emits a corresponding laser beam to scan the printing cylinder. The printing cylinder (plateless printing plate), made of photosensitive material, is exposed to light, forming an image that can absorb ink or toner, which is then transferred to a substrate such as paper.

[0003] Existing digital printing paper has poor ink absorption, which means that the ink cannot dry quickly after printing. When users touch the paper after printing, the ink on the paper is not yet dry, causing ink to adhere to the user's hands and even blurring the printed text. Therefore, we have proposed a fast-drying inkjet digital printing paper. Utility Model Content

[0004] The purpose of this invention is to provide a quick-drying inkjet digital printing paper to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a quick-drying inkjet digital printing paper, comprising:

[0006] The base layer has an ink-absorbing layer on its top surface, a flame-retardant board layer on its top surface, and an upper ink-absorbing layer on its surface.

[0007] A wear-resistant layer is fixedly connected to the bottom surface of the base layer.

[0008] Preferably, the base layer is made of short-fiber wood pulp material, and the tiny pores between the short fibers in the short fibers rapidly absorb liquid through capillary action.

[0009] Preferably, the ink-absorbing layer is made of cotton pulp, which has a uniform porous fiber structure, allowing ink to penetrate quickly without spreading, and is environmentally friendly and biodegradable.

[0010] Preferably, the flame-retardant plate layer is made of polydimethylsiloxane material, which has strong resistance, excellent waterproof and oil-proof properties, and good high-temperature resistance.

[0011] Preferably, the ink-absorbing layer has a cavity, and the cavity is filled with ink-absorbing particles.

[0012] Preferably, the ink-absorbing particles are made of precipitated silica material, which has a capillary pore size of 10-50 nm, precisely matching the size of ink molecules (such as water-based dyes with a particle size of about 20 nm). After surface modification (such as amination), it can directionally adsorb specific ink components.

[0013] Preferably, the wear-resistant layer is a porous nano-silica-based coating, which excels in ink absorption, blocking, and surface modification. Nano-silica has high thermal stability, and the coating is not easily decomposed or ineffective in high-temperature environments, making it suitable for protective and insulating applications in high-temperature environments. The porous nano-silica-based coating has good resistance to chemical media such as acids, alkalis, and salts, effectively protecting the substrate from corrosion. The chemical inertness of nano-silica makes it difficult to be oxidized in oxidizing environments, extending the service life of the coating. Nano-silica is an inorganic non-metallic material that is non-toxic, harmless, and environmentally friendly, meeting the requirements of green environmental protection.

[0014] Preferably, the upper ink-absorbing layer is an inorganic ink-absorbing coating. Inorganic ink-absorbing coatings have a fast ink absorption speed, and their porous structure allows ink to quickly penetrate and be absorbed, reducing drying time. Inorganic ink absorbers have good compatibility with ink, maintaining color vibrancy and stability. Inorganic materials possess good chemical stability and weather resistance, making the coating less prone to fading or deterioration. Furthermore, the inorganic ink-absorbing coating does not contain organic solvents, meeting environmental protection requirements.

[0015] The beneficial effects of this utility model are:

[0016] 1. This quick-drying inkjet digital printing paper enhances ink absorption and achieves quick-drying by incorporating a base layer and an ink-absorbing layer. The flame-retardant board layer provides strong resistance, excellent waterproof and oil-proof properties, and good high-temperature resistance.

[0017] 2. This quick-drying inkjet digital printing paper can accelerate the ink absorption speed of the paper by setting ink-absorbing particles, which further improves the quick-drying effect of the paper. The abrasion-resistant layer increases the abrasion resistance of the paper and improves the service life of the paper. Attached Figure Description
