Problems solved by technology

[0016] These methods take into account the adaptability of the hydrophilicity of the coating material to water-based inks, but do not pay enough attention to the adhesion, superposition, migration, etc. of the ink particles on the membrane material, and the comprehensive properties of the membrane material are not conducive to obtaining high-quality color inkjet printing. and thermal transfer effects

Embodiment 1

[0088] Add 330 kg of water, 60 kg of potato starch, 10 kg of polyvinyl alcohol (PVA), 10 kg of carboxymethyl cellulose (CMC), 0.12 kg of urea, 1.2 kg of hydrogen peroxide (40wt % concentration), 0.3-0.6 kg of tributyl phosphate, stirred at 80 ° C to make the mixture gelatinized, dissolved, thinned, stirred for 1.5 hours to end the reaction, then cooled to room temperature (25 ° C), and then added about Stir and mix 5 kg of CMS, adjust the viscosity to about 4000 cp (rotational viscosity, test temperature: 25° C.), and filter to obtain a hydrocolloid solution (ie, a coating composition).

[0089] The above colloidal solution was coated at 110g / m by air knife coating 2 Wet strength base paper (sold by Dongguan Chang'an Changzhong Paper Co., Ltd.), after drying, rewinding, and cutting, it becomes heat transfer paper of different specifications.

Embodiment 2-6

[0090] Embodiment 2-6: Repeat embodiment 1, that is, the basic operation process is the same as embodiment 1, but the ratio of materials is shown in the table below.

Abstract

The invention relates to a coating component for heat transfer paper, the heat transfer paper and a manufacturing method of the heat transfer paper. The coating component is obtained by reacting and gelatinizing starch, cellulose and polyvinyl alcohol as main resin or base materials and hydrogen peroxide and urea as a molecular structure regulator at high temperature, and then, adding high-densification-degree carboxymethyl starch sodium (CMS) as a viscosity modifier. The coating component is aqueous colloid resin with viscosity of 2500-6500cp, preferably, 3000-6000cp and further preferably, 4000-5500cp. The coating component is used for the heat transfer paper, and has a good effect in attaching, overlapping, transferring ink particles.

Description

technical field [0001] The invention relates to the preparation of a water-based coating resin used for coating the surface of heat-transfer base paper, and a method for manufacturing commercial heat-transfer paper from the coating resin material by means of air-knife coating. Specifically, the water-based resin coating material can be attached to the surface of the paper, thereby forming a surface film layer on the surface of the paper that can carry digital color patterns composed of four water-based inks of yellow, magenta, cyan, and black. The digital color patterns The inkjet printing method is used to reproduce the polymer film layer, and then through the thermal sublimation process, the pattern is transferred to the surface of the fiber fabric. [0002] The water-based polymer ink-receiving resin material for paper coating involved in the invention belongs to the technical field of fine functional polymer materials. Background technique [0003] Sublimation transfer ...
