preparation example Construction

[0031] see figure 1 , figure 1 It is a schematic flow diagram of an embodiment of the preparation method of the sublimation transfer paper of the present application, and the preparation method includes:

[0032]Step S11: 100 parts by mass of sodium carboxymethylcellulose, 10-30 parts by mass of starch, 10-50 parts by mass of pigment, 1-3 parts by mass of cationic polymer, 0.01-0.05 parts by mass of defoamer, 0.01-2 parts by mass of Mix parts by mass of dispersant, 0.01-3 parts by mass of pH regulator and 0.01-2 parts by mass of bactericide, and disperse evenly to obtain top coating;

[0033] Wherein, starch is ungelatinized starch;

[0034] Step S12: coating a topcoat on the base paper to obtain thermal transfer sublimation paper.

[0035] Wherein, starch is added in the form of dispersion liquid of starch in cold water. It should be pointed out that the "cold water" here is not limited to water with a very low temperature, as long as the temperature can make the starch i...

Embodiment 1

[0041] 100 parts of sodium carboxymethylcellulose (degree of substitution 0.8), 20 parts of ungelatinized tapioca starch, 30 parts of heavy calcium carbonate, 1 part of cationic alkylketene dimer, 0.02 parts of polyethylene glycol, 0.1 part of sodium polyacrylate, 0.05 part of isothiazolinone, and 0.6 part of sodium hydroxide are mixed together according to the order of the formula in Table 1, and after high-speed dispersion, a uniformly dispersed coating is obtained;

[0042] The above coating is 42g / m in gram weight 2 The base paper is coated on one side, and the coating amount is 4g / m 2 ; After the coating is completed, drying treatment is carried out to obtain sublimation transfer paper.

Abstract

The invention discloses a thermal dye sublimation transfer paper coating, thermal dye sublimation transfer paper and a preparation method thereof, wherein the thermal dye sublimation transfer paper coating comprises sodium carboxymethyl cellulose, starch, a pigment, a cationic polymer and an additive, wherein the starch is non-gelatinized starch. By means of the mode, the water absorption of the thermal dye sublimation transfer paper can be improved, the drying speed of the printing ink paper is increased, and the printing ink transfer rate and the printing definition can be improved.

Description

technical field [0001] The present application relates to the technical field of papermaking, in particular to a thermal sublimation transfer paper coating, a thermal sublimation transfer paper and a preparation method thereof. Background technique [0002] Dye-sublimation transfer printing is to use inkjet printing, offset printing, screen printing, gravure printing and other printing methods to print text, patterns and other graphics that need to be printed on a On the special paper, the paper printed with graphics and text is superimposed on the substrate, and the ink on the sublimation transfer paper becomes gaseous by means of heating and pressure, and combines with the substrate to transfer the graphics and text to the substrate. things. In this process, the paper used for transfer is called sublimation transfer paper. [0003] With the development of sublimation transfer printing technology, the current sublimation transfer paper has been difficult to meet people's ...
