Embodiment 1

[0039] First prepare the white layer slurry, and its proportioning ratio is as follows:

[0040]

[0041] Dissolve and mix water, additives, polyurethane resin emulsion and acrylic resin emulsion in the stirring and dissolving tank evenly, put them into the dispersion tank, add titanium dioxide, disperse for 30-50 minutes, and then pass through the sand mill for 1-5 times. , discharge the slurry for coating the white layer.

[0042] Coat a magnetic layer on a 200-micron paper substrate, and then apply a white layer with a thickness of 6 μm on the magnetic layer by extrusion coating, then coat a heat-sensitive layer on the other side of the paper substrate, and then coat the heat-sensitive layer on the other side of the paper substrate. A heat-sensitive protective layer is coated on the layer, and a heat-sensitive magnetic recording paper with a white layer is prepared for performance testing.

Embodiment 2

[0044] First prepare the white layer slurry, and its proportioning ratio is as follows:

[0045]

[0046] Dissolve the mixed solvent, additives, acrylic resin and UV photocurable resin in the stirring and dissolving tank and mix evenly, then put it into the dispersion tank, add titanium dioxide, disperse for 30-50 minutes, and then pass through the sand mill for 1-5 times Finally, put the material into the stirring tank, add the initiator dissolved in the solvent, stir and mix for 60-90 minutes, and release the slurry for coating the white layer.

[0047]Coat a magnetic layer on a 200-micron paper substrate, and then coat a white layer with a thickness of 6 μm on the magnetic layer by anilox roller coating, and then coat a heat-sensitive layer on the other side of the paper substrate, and then heat A heat-sensitive protective layer is coated on the sensitive layer to prepare a heat-sensitive magnetic recording paper with a white layer for performance testing.

Embodiment 3

[0049] First prepare the white layer slurry, and its proportioning ratio is as follows:

[0050]

[0051] Dissolve the mixed solvent, additives, polyurethane resin and UV photocurable resin in the stirring and dissolving tank and mix evenly, then put it into the dispersion tank, add titanium dioxide, disperse for 30-50 minutes, and then pass through the sand mill for 1-5 times Finally, put the material into the stirring tank, add the initiator dissolved in the solvent, stir and mix for 60-90 minutes, and release the slurry for coating the white layer.

[0052] Coat the magnetic layer on the 200 micron paper substrate, then coat the heat-sensitive layer on the other side of the paper substrate, then coat the heat-sensitive protective layer on the heat-sensitive layer, and then coat the magnetic layer with a wire bar A white layer with a thickness of 6 μm was coated to prepare a thermosensitive magnetic recording paper with a white layer, and a performance test was performed....

Abstract

The invention discloses thermo-sensitive magnetic recording paper with a white layer. The thermo-sensitive magnetic recording paper with the white layer comprises a paper base material, a thermo-sensitive layer, a thermo-sensitive protective layer, a magnetic layer and the white layer. The white layer is prepared from hydroxyl polyurethane, acrylic resin, UV light-cured resin, a photoinitiator and titanium dioxide. The white layer can well cover a black magnetic layer, the requirement for printing an exquisite pattern can be met, the purpose of the attractive appearance is achieved, and the white layer has the high abrasion resistance and does not contaminate or corrode a magnetic head.

Description

technical field [0001] The invention relates to a heat-sensitive magnetic recording paper, in particular to a heat-sensitive magnetic recording paper with a white layer. Background technique [0002] Thermosensitive magnetic recording paper is widely used as a ticket carrier in railways, highways, subways, parking lots, airports and other places. At present, the color of the magnetic recording layer of thermosensitive magnetic recording paper is black. Because black is not easy to cover, it can only be printed with Text or pattern colors with large differences in black, such as white, have a single color, which cannot meet the needs of printing exquisite patterns. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat-sensitive magnetic recording paper with a white layer to improve the effect of color printing, aiming at the shortcomings of the existing heat-sensitive magnetic recording paper. [0004] In order ...
