Embodiment 1

[0021] Embodiment 1: An inkjet printing film, including a substrate 13 and an ink-absorbing coating 115. The substrate 13 uses a colorless PET transparent substrate (purchased by Suzhou Zhanxingda Electronic Materials Co., Ltd.). The ink-absorbing coating 115 is divided into two layers, and each layer has holes, and the holes become larger in the direction from being away from the substrate to closer to the substrate. The hole in the layered structure 11 away from the substrate is 20-50 nm, and the hole in the layered structure 12 near the substrate is 50-100 nm.

[0022] Preparation:

[0023] S1. Preparation of ink-absorbing coating:

[0024] Ink-absorbing coating layered structure 1 coating preparation: the mass fraction of 15% porous silica (WACKER Chemie (China) Co., Ltd.) with a pore size of 20-50nm is used in a high-speed disperser at a line of 10m / s Disperse at a high speed for 1 hour to prepare a silica dispersion. The silica dispersion, polyvinyl alcohol PVA-205 (China ...

Embodiment 2

[0028] Embodiment 2: An inkjet printing film, including a substrate and an ink-absorbing coating. The substrate uses a colorless PET transparent substrate (purchased by Suzhou Zhanxingda Electronic Materials Co., Ltd.). The ink-absorbing coating is divided into four layers, and each layer has holes, and the holes become larger in the direction from being away from the substrate to closer to the substrate. The holes increase in order from the direction away from the substrate to the direction closer to the substrate, and they are 20-30nm, 30-50nm, 50-80nm, 80-100nm.

[0029] Preparation:

[0030] S1. Preparation of ink-absorbing coating:

[0031] Ink-absorbing coating layered structure 1 coating preparation: the mass fraction of 20% porous aluminum oxide with a pore size of 20-30nm (Sasol China Chemical Co., Ltd.) is used with a high-speed disperser at a line speed of 15m / s Disperse at a high speed for 2 hours to prepare an aluminum oxide dispersion. Combine aluminum oxide disper...

Embodiment 3

[0037] Embodiment 3: An inkjet printing film, including a substrate and an ink-absorbing coating. The substrate uses a colorless PET transparent substrate (purchased by Suzhou Zhanxingda Electronic Materials Co., Ltd.). The ink-absorbing coating is divided into six layers, and each layer has holes. The holes are 20-30nm, 20-30nm, 30-50nm, 50-80nm, 50-80nm, 80-100nm from the direction away from the substrate to the direction closer to the substrate.

[0038] Preparation:

[0039] S1. Preparation of ink-absorbing coating:

[0040] The coating preparation of the ink-absorbing coating layered structure 1: the mass fraction of 15% porous silica (WACKER Chemie (China) Co., Ltd.) with a pore size of 20-30nm is used in a high-speed disperser at a line of 15m / s Disperse at high speed for 2 hours to prepare a silica dispersion. The silica dispersion liquid, polyvinyl alcohol PVA-205 (China Taiwan Changchun Chemical Group), polyvinyl alcohol PVA-235 (Kuraray International Trading (Shanghai...

Abstract

The invention relates to the field of ink-jet printing films and particularly relates to an ink-jet printing film and a preparation method thereof. The ink-jet printing film provided by the invention comprises a substrate and an ink absorption coating, wherein the substrate is made of a transparent material; the ink absorption coating is in a multilayered lamellar structure; the ink absorption coating contains a coloring dye; the ink absorption coating is blue or white. According to the ink-jet printing film, the dye is added to the ink absorption layer so that a blue or white bottom color can be finished by the uniform ink absorption layer; a coloring layer does not need to be additionally arranged so that the cost can be effectively reduced; the oil absorption amount of the coating is improved through a manner of arranging the ink absorption coating with the lamellar structure.

Description

Technical field [0001] The invention relates to the field of inkjet printing films, in particular to an inkjet printing film and a preparation method thereof. Background technique [0002] With the development of technology, digitally printed inkjet printing film is a new type of imaging film that has developed rapidly in recent years. At present, a blue or white PET film is selected as a substrate for medical film, coated with an ink-absorbing coating. The apparent quality of the film is also very good, but the cost is too high. [0003] The ink absorption and ink absorption stability of the ink-absorbing coating have a greater impact on the printing effect. The ink absorption has a major impact on the color expression of the film, and the ink absorption stability has a direct impact on the film's waterproof ability. Under normal circumstances, increase the thickness of the ink-absorbing coating to increase the ink absorption, or use dyes with better electrostatic adhesion to the...
