Abstract

The invention relates to the technical field of papermaking, and discloses a thermal sublimation transfer paper coating with high ink transfer rate and fast ink drying rate and a preparation method thereof, which comprises nano-cellulose, carboxymethyl cellulose, and modified kaolin , Insoluble starch. In the present invention, nanocellulose is added to the coating to greatly increase the ink transfer rate of paper, insoluble starch is added to greatly increase the drying rate of ink, and modified kaolin is added to effectively improve the ink absorption of paper, and the surface strength of paper is also improved. A certain degree of improvement.

Description

Technical field [0001] The present invention relates to the technical field of papermaking, particularly to a sublimation transfer paper coating and preparation method thereof, and a high rate of ink transfer both fast ink drying rate. Background technique [0002] Sublimation Transfer, refers to a special paper in the thermal sublimation transfer process used. Particular use are: printing a dye sublimable inks on a transfer paper sublimation (printing graphics is mirror-inverted form), and then printed with graphics paper laminated with the substrate, the heating, plus under pressure, into the interior of the ink sublimation of gaseous substrates, in turn transferred to the graphic substrate, to complete the transfer. [0003] Sublimation Transfer is a functional coated paper, giving the paper sheet by the ink absorbing coating composition, and the release isolation three basic functions. The ink absorbing function can better absorb ink jet printing ink; isolation function is to...
