Problems solved by technology

At present, there are high-gloss color inkjet printing papers with various coatings on the market, but they all have defects such as poor ink absorption, weak ink fixation, poor highlight effect, and poor color clarity. Unstable, the product quality is not stable enough, and the production qualification rate is also low. During large-scale coating production, due to the unstable formula, the production often occurs intermittently, which reduces the production efficiency and greatly affects the quality of the product.

Abstract

The invention relates to a formula and a preparation method for a high gloss color ink-jet printing paper coating. According to the method, 100 parts of pure water, 50-60 parts of nano-silica, 5-10 parts of a cationic color fixing agent, 3-6 parts of a 10% polyvinyl alcohol aqueous solution, 1-3 parts of an acrylic emulsion, and 0.5-1 part of a defoamer are subjected to preparation processing and coating. The color ink-jet printing paper prepared according to the formula and the preparation process provided by the invention not only has high gloss, high ink absorbency high color reducibility, high color density, high resolution, high pull-out capacity and other characteristics, but also has stable formula, the product qualification rate reaches over 95%, 24h uninterrupted coating production can be realized, and the production efficiency and product qualified rate are improved. Thus, the formula and the preparation method are suitable for wide popularization and use.

Description

Technical field [0001] The invention relates to a coating formula of high-gloss color ink-jet printing paper and a preparation method thereof. Background technique [0002] Color inkjet printing paper is also called color inkjet paper or color inkjet paper, or digital printing paper. Color inkjet paper is very different from ordinary paper because color inkjet printing usually uses water-based ink, while ordinary paper is accepted After water-based ink, it will quickly absorb and spread around, so the usual color inkjet printing paper has a special coating, so that it not only has good ink absorption, but also has strong ink fixation and will not diffuse to the periphery , So as to completely maintain the original printing color and clarity. At present, various coatings of high-gloss color inkjet printing papers have appeared on the market, but they all have defects such as poor ink absorption, poor ink fixation, poor gloss effect, and poor color clarity. Unstable, insufficient...
