Embodiment 1

[0018] Waterproof inkjet printing medium, including a sheet-shaped waterproof substrate, the sheet-shaped waterproof substrate is coated with a coating liquid on one side to form an ink-absorbing waterproof layer, and the coating liquid is prepared by dissolving the following raw materials and additives in purified water Preparation: silicon dioxide, 38 parts by weight; polyvinyl alcohol, 3 parts by weight; cationic acrylic acid, 60 parts by weight; dispersant, 0.1 parts by weight; whitening agent, 0.1 parts by weight.

[0019] As shown in the accompanying drawing, the preparation method of the above-mentioned waterproof inkjet printing medium comprises the following steps

[0020] 1.) Preparation of coating liquid: first add 38 parts by weight of silicon dioxide to 300 parts by weight of pure water, and stir continuously to disperse it. During the dispersion process, add 0.1 parts by weight of dispersant and disperse for 40 minutes to make Silica is evenly dispersed; then add...

Embodiment 2

[0022] Embodiment 2: Embodiment 2 is basically the same as Embodiment 1, the difference is that

[0023] The coating solution in this embodiment is prepared from the following raw materials and auxiliary agents: aluminum hydroxide, 25 parts by weight; polyvinyl alcohol, 5 parts by weight; cationic acrylic acid, 20 parts by weight; dispersant, 0.15 parts by weight; Brightener, 0.05 parts by weight.

[0024] The steps of preparing the coating solution in this embodiment are: firstly add 25 parts by weight of aluminum hydroxide to 200 parts by weight of pure water, and stir continuously to disperse it. During the dispersion process, add 0.15 parts by weight of a dispersant to disperse 30 minutes to make the aluminum hydroxide dispersed evenly; then add 5 parts by weight of polyvinyl alcohol and continue to stir; then add 20 parts by weight of cationic acrylic emulsion, mix and stir for 50 minutes, add 0.05 parts by weight of whitening agent, continue to stir evenly Thereafter, a...

Embodiment 3

[0025] Embodiment three: Embodiment three is basically the same as embodiment two, the difference is that

[0026] The coating solution in this embodiment is prepared from the following raw materials and auxiliary agents: aluminum hydroxide, 10 parts by weight; polyvinyl alcohol, 2 parts by weight; cationic acrylic acid, 40 parts by weight; dispersant, 0.05 parts by weight; Brightener, 0.15 parts by weight.

[0027] The steps of preparing the coating solution in this example are as follows: first add 10 parts by weight of aluminum hydroxide to 250 parts by weight of pure water, and stir continuously to disperse it. During the dispersion process, add 0.05 parts by weight of a dispersant to disperse 50 minutes to make aluminum hydroxide dispersed evenly; then add 2 parts by weight of polyvinyl alcohol and continue to stir; then add 40 parts by weight of cationic acrylic emulsion, mix and stir for 70 minutes, add 0.15 parts by weight of whitening agent, continue to stir evenly T...

Abstract

The invention discloses a waterproofing ink-jet printing media and preparation method thereof. The waterproofing ink-jet printing media disclosed in the invention comprises a sheet waterproof substrate, wherein, one side of the sheet waterproof substrate is coated with a coating liquid to form an ink-absorbing waterproof layer, the coating liquid is prepared by dissolving the following ingredients in purified water: 10-40 weight portions of silicon dioxide or aluminium hydroxide, 2-5 weight portions of polyvinyl alcohol and 20-60 weight portions of cationic acrylic acid. The preparation method disclosed in the invention comprises a step of preparing the coating liquid and a step of coating the coating liquid on the sheet waterproof substrate. According to the invention, after printing, the cationic acrylic acid in the ink-absorbing waterproof layer reacts with the anionic ink to form water-insoluble precipitates, so that the waterproof effect can be realized. The waterproofing ink-jet printing media can bear rain, can be used in outdoor environments, and is convenient for preservation.

Description

technical field [0001] The invention relates to the technical field of inkjet printing media, in particular to a waterproof inkjet printing medium and a preparation method thereof. Background technique [0002] Inkjet printing inks are divided into two systems, one is water-soluble dye-based ink, and the other is water-insoluble pigment-based ink in which pigment solids are dispersed in a water-based system. Both inks are strong Anionic ink. The preparation of traditional inkjet printing medium is usually: on the base material, coat the ink-absorbing layer containing polyvinyl alcohol or methyl cellulose, polyvinyl alcohol or methyl cellulose are as film-forming agent and thickener, its absorption The principle of ink is swelling and ink absorption. However, the traditional inkjet printing media cannot be waterproof after printing, and the printing media cannot be wiped after inkjet printing, and a large amount of ink will overflow immediately after encountering water, whi...
