Abstract

Disclosed is digital paint, which is characterized by comprising specific components of 8-10 parts by weight of a high water-retention resin of polyvinyl alcohol, 2-3 parts by weight of polyvinyl acetate latex, 1-2 parts by weight of titanium dioxide, 10-13 parts by weight of nano-silica, 2-5 parts by weight of a master batch, 15-30 parts by weight of light calcium carbonate, 0.1-0.3 part by weight of a dispersant, 0.05-0.1 part by weight of an antifoaming agent, 1-3 parts by weight of a cationic fixing agent, and 30-50 parts by weight of deionized water. The completely hydrolyzed polyvinyl alcohol has a mediate or low molecular, the efficacy of ink absorption and fast drying, and characteristics of appropriate viscosity and the like. The nano-silica has an extremely great ultraviolet absorption function and an infrared reflection property, and has perfect ink fixing performance. The master batch is a thermoplastic hollow sphere-shaped aqueous dispersion and has functions of enhanced hiding power and improved fullness and lustrousness of paint. The cationic fixing agent is ammonium salt-containing polyacrylic acid, which can improve print effect.

Description

technical field [0001] Digital paint is characterized in that its specific components and weight percentages are: high water retention resin polyvinyl alcohol 8-10, polyacetate latex 2-3, titanium dioxide 1-2, nano silicon dioxide 10-13, masterbatch 2-5, light calcium carbonate 15-30, dispersant 0.1-0.3, defoamer 0.05-0.1, cationic color fixing agent 1-3, deionized water 30-50. Background technique [0002] With the rapid growth of sales of digital cameras and camera phones, the rapid popularization of computers, and the increasing use of color inkjet printers, the demand for high-quality digital photo paper and color inkjet paper is increasing, and there are many such papers on the market. It is mainly imported, and the price is high, while the domestic production is relatively small and the quality is average, especially the research on low-cost, high-quality digital photo paper coating formulations is less. However, the paint formulation has disadvantages such as poor wa...
