Problems solved by technology

However, the problem of using sulfuric acid paper as film for laser printing is: on the one hand, sulfuric acid paper will produce a large amount of waste gas sulfuric acid in the production process, which has brought serious harm to the environment. The country has made it clear that it will close all Sulfuric acid paper manufacturers
On the other hand, there are many disadvantages in the use of sulfuric acid paper: first, due to the residual acid of sulfuric acid paper, yellowing will appear in a short period of time, and it will become very brittle, so sulfuric acid paper cannot be archived for a long time The second is that sulfuric acid paper is not waterproof and cannot be used under harsh conditions; the third is that sulfuric acid paper is a kind of paper obtained after special production of sulfuric acid. The sulfuric acid paper used as a film has poor dimensional stability because the carrier is paper.

Embodiment 1

[0019] The laser printing film includes a transparent waterproof film base, the transparent waterproof film base is coated with a coating liquid on one side to form a toner absorption coating, and the coating liquid is prepared by dissolving the following raw materials and additives in purified water, Aluminum hydroxide, 18 parts by weight; polyvinyl alcohol, 30 parts by weight; boric acid, 0.5 parts by weight; dispersant, 0.1 parts by weight; whitening agent, 0.1 parts by weight.

[0020] As shown in the accompanying drawing, the preparation method of the above-mentioned laser printing film comprises the following steps

[0021] 1.) Prepare the coating solution: first add 18 parts by weight of aluminum hydroxide to 200 parts by weight of pure water, and continue to stir; then add 0.1 parts by weight of dispersant, and continue to stir; then add 30 parts by weight of polyvinyl alcohol, And add 0.5 parts by weight of boric acid (to make it cross-linked with polyvinyl alcohol to...

Embodiment 2

[0026] Embodiment 2: Embodiment 2 is basically the same as Embodiment 1, the difference is that

[0027] The coating solution in this example is prepared from the following raw materials and additives: silicon dioxide, 10 parts by weight; acrylic emulsion, 40 parts by weight; dispersant, 0.05 parts by weight; whitening agent, 0.15 parts by weight.

[0028] The steps for preparing the coating solution in this example are: first add 10 parts by weight of silicon dioxide to 220 parts by weight of pure water, and continuously stir; then add 0.05 parts by weight of a dispersant, and continue to stir; then add 40 parts by weight of The acrylic emulsion is continuously stirred; finally, 0.15 parts by weight of whitening agent is added, and continuously stirred until uniform, so as to obtain a coating liquid.

Embodiment 3

[0029] Embodiment three: Embodiment three is basically the same as embodiment two, the difference is that

[0030] The coating solution in this embodiment is prepared from the following raw materials and additives: calcium carbonate, 20 parts by weight; VAE emulsion, 50 parts by weight; dispersant, 0.15 parts by weight; whitening agent, 0.05 parts by weight.

[0031] The steps of preparing the coating liquid in this embodiment are: first add 20 parts by weight of calcium carbonate to 250 parts by weight of pure water, and continue to stir; then add 0.15 parts by weight of a dispersant, and continue to stir; then add 50 parts by weight of VAE The emulsion is continuously stirred; finally, 0.05 parts by weight of whitening agent is added, and the mixture is continuously stirred until it is uniform, so as to obtain a coating liquid.

[0032] In the present invention, when preparing the coating liquid, adding a dispersant can uniformly disperse calcium carbonate, silicon dioxide o...

Abstract

The invention discloses a laser printing film and its preparation method. The laser printing film of the invention includes a transparent and waterproof film base, on one side of which a coating liquid is coated so as to form a toner adsorption coating. The coating liquid is prepared by dissolving the following raw materials in purified water: 10-20 parts of toner adsorbent and 30-50 parts of adhesive by weight. The preparation method of the invention comprises the steps of preparing the coating liquid and coating the transparent and waterproof film base with the coating liquid. The laser printing film of the present invention has excellent printing effect, good waterproof effect, good dimensional stability and long-term archiving performance. In addition, the film can be used to replace parchment films in laser printing and also can be used in plotter printing.

Description

technical field [0001] The invention relates to the technical field of printing film, in particular to a laser printing film and a preparation method thereof. Background technique [0002] Sulfuric acid paper, also known as plate-making sulfuric acid transfer paper, is not only used for engineering drawing and printing, but also widely used as film for laser printing. However, the problem of using sulfuric acid paper as film for laser printing is: on the one hand, sulfuric acid paper will produce a large amount of waste gas sulfuric acid in the production process, which has brought serious harm to the environment. The country has made it clear that it will close all Sulfuric acid paper manufacturer. On the other hand, there are many disadvantages in the use of sulfuric acid paper: first, due to the residual acid of sulfuric acid paper, yellowing will appear in a short period of time, and it will become very brittle, so sulfuric acid paper cannot be archived for a long t...
