Abstract

The invention discloses a coating fluid for preparing inkjet high-gloss waterproof printing paper, which comprises the following components in parts by weight: 10-40 parts of ink powder adsorbent, 30-55 parts of adhesive, 0.05-0.15 part of whitener, 0.05-0.15 part of dispersing agent, 2-5 parts of defoaming agent, 1-3 parts of neutralizer and 140-200 parts of distilled water. The adhesive is a cationic water-based polyurethane emulsion. The invention also discloses a printing paper for preparing the coating fluid and a preparation method thereof. The coating fluid has the advantages of no toxicity, no odor, favorable bonding property and favorable water resistance; the coating has favorable weather resistance and can bear sunlight irradiation for a long time; the coating has the advantages of high internal-structure strength and favorable adhesion for the substrate; and the coating printing surface has favorable scratch resistance. The printing paper prepared from the coating fluid has the advantages of ultrahigh drying rate after ink absorption, bright color, high color reduction degree, no piling phenomenon and favorable waterproof effect; and the output image has clear and sharp picture.

Description

technical field

[0001] The invention relates to the technical field of ink-jet photo paper, in particular to a coating solution for ink-jet high-gloss waterproof photo paper, a photo paper and a preparation method for the photo paper. Background technique

[0002] With the enhancement of people's awareness of environmental protection and energy, especially the strict restrictions on the content of volatile organic compounds (VOC) in the coating liquid system by various environmental protection regulations, the issue of material safety has attracted more and more attention from consumers. The inkjet printing coating Adhesives and other additives put forward higher standards and requirements.

[0003] Most of the adhesives of existing photographic papers are acrylic coatings, and acrylic emulsions are used as adhesives in inkjet printing coatings to reduce the content of highly hydrophilic hydroxyl functional groups in the molecular structure of the coating liquid. The water ...
