Embodiment 1

[0035] The preparation method of an environment-friendly high-gloss weak-solvent photo medium of the present invention comprises the following steps:

[0036] Step 1: Preparation of substrate 3; use Nanya's double-light PP synthetic paper with a thickness of 140 μm, a width of 1.29m, and a length of 3000m.

[0037] Step 2: Preparation of adhesion promotion layer 2 coating; weigh 50kg polyurethane emulsion, 26.6kg deionized water, 0.1kg defoamer, 0.1kg wetting agent, and add the above components in order to the mixing tank , start the agitator, stir for 0.5h to make the material mix evenly, filter with a 200-mesh filter, put it into a storage barrel and seal it for storage until coating.

[0038]Step 3: Preparation of high-gloss weak-solvent ink-absorbing layer 3; first weigh 64kg of polyurethane acrylate modified emulsion, add it to the batching bucket, start the agitator, and set the number of revolutions to 400RPM (not too fast to avoid foaming); then Add the following mate...

Abstract

The invention relates to the field of digital images, and discloses an environment-friendly high-luster weak solvent portrait medium and a preparation method thereof. The environment-friendly high-luster weak solvent portrait medium comprises a base material, an adhesion promoting layer and a high-luster weak-solvent blotting layer; one surface of the base material is provided with the adhesion promoting layer; and the surface, far away from the base material, of the adhesion promoting layer is provided with the high-luster weak-solution blotting layer. The high-luster weak-solution blotting layer comprises the following compositions in parts by mass: 64 parts of a polyurethane acrylate modified emulsion, 32 parts of an acrylic resin emulsion, 3 parts of an antistatic agent, 0.1 part of a brightening agent, 0.5 part of a levelling agent, 0.2 part of a wetting agent, and 0.2 part of an antifoaming agent. Organic solvents such as ethanol, methanol, isopropanol and the like are not employed in the preparation process, so that discharge of volatile organic compounds (VOC) is eliminated; discharge of toxic harmful solvents such as cyclohexanone, butanone and the like is eliminate during usage, forced ventilation is not needed, and the problems are solved that a high-luster weak-solvent portrait medium prepared from a conventionally used acrylic emulsion is easy to adhere and cannot unwind.

Description

technical field [0001] The invention relates to the field of digital imaging, in particular to an environmentally friendly high-gloss weak-solvent photo medium for digital image inkjet printing output and a preparation method thereof. The photo medium has high resolution and high weather resistance, and is compatible with weak-solvent ink, Solvent based inks, UV curable inks and Latex inks. Background technique [0002] Inkjet printing technology is widely used in cultural propaganda, advertising promotion, portrait photography, medical imaging, industrial imaging and military imaging and other fields. With the advancement of digital inkjet printing technology, the requirements for the resolution, weather resistance, UV resistance, ink absorption, and ink drying speed of inkjet printing media are getting higher and higher, especially for the volatility of inkjet printing media during production and use. The limitation of organic compound VOC emission is becoming more and mo...
