Embodiment 1

[0024] The present embodiment provides a heat-sensitive embossed paper coating, the components of which are shown in Table 1:

[0025] Table 1

[0026] components Mass percentage (%) Lactone Compound Dyes 5％ Phenylphenol developer 15％ expandable microspheres 30％ Adhesive 10％ filler 35％ Sensitizer 2％ Antioxidants 1％ lubricant 2％

[0027] According to the above ratio, the auxiliary agent was rapidly stirred in a high-speed mixer at 800rpm for 5min; then the expandable microspheres, dye and color developer were added, and stirred and dispersed at 500rpm for 5min to prepare heat-sensitive embossed paper coating.

[0028] The above heat-sensitive embossed paper coating is coated on the heat-sensitive embossed base paper by brushing.

Embodiment 2

[0030] The present embodiment provides a heat-sensitive embossed paper coating, and the components of the coating are as shown in Table 2:

[0031] Table 2

[0032] components Mass percentage (%) Lactam ring compound dye 8％ Salicylic acid developer 18％ expandable microspheres 30％ Adhesive 10％ filler 30％ Sensitizer 1％ Antioxidants 1％ lubricant 2％

[0033] According to the above ratio, the auxiliary agent was rapidly stirred in a high-speed mixer at 1200 rpm for 3 minutes; then the expandable microspheres, dye and color developer were added, and stirred and dispersed at 800 rpm for 3 minutes to obtain heat-sensitive embossed paper coating.

[0034] The above heat-sensitive embossed paper coating is coated on the heat-sensitive embossed base paper by a curtain coating method.

Embodiment 3

[0036] The present embodiment provides a heat-sensitive embossed paper coating, the components of which are shown in Table 3:

[0037] table 3

[0038] components Mass percentage (%) Spiral pyran ring compound dyes 5％ Methylene bis-naphthol developer 15％ expandable microspheres 35％ Adhesive 10％ filler 30％ Sensitizer 1％ Antioxidants 2％ lubricant 2％

[0039] According to the above ratio, the auxiliary agent was rapidly stirred in a high-speed mixer at 1000rpm for 4min; then the expandable microspheres, dye and color developer were added, and stirred and dispersed at 600rpm for 4min to obtain heat-sensitive embossed paper coating.

[0040] The above heat-sensitive embossed paper coating is coated on the heat-sensitive embossed base paper by spraying.

[0041] When the expandable microsphere is heated, its outer shell softens, and the internal alkane gas vaporizes to expand the whole to achieve a convex effect. It pr...

Abstract

The invention discloses a thermosensitive convex paper coating as well as a preparation method and application thereof. The coating is prepared from the following components in percentage by mass: 5-10 percent of a dye, 15-20 percent of a color developing agent, 25-35 percent of expandable microspheres and 50-55 percent of an aid. The expandable microspheres are added into the thermosensitive convex paper coating, when being heated, a shell of the thermosensitive convex paper coating is softened, alkane gas in the thermosensitive convex paper coating is gasified to enable the thermosensitive convex paper coating to be expanded integrally, the convex effect is achieved, a convenient and low-cost braille printing mode is provided, and more convenient life can be provided for people with visual problems. Besides, the expandable microspheres are white and occupy a certain volume, so that the use amount of filler can be reduced; and the overall use amount of the coating is reduced during coating, and the effects of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a heat-sensitive embossed paper coating and a preparation method and application thereof. Background technique [0002] In recent years, the use of thermal paper has become more and more extensive, and the demand for use has also increased year by year. From common cash register receipts, freight logistics labels, food labels and metering labels for different applications in supermarkets, to transportation bills, lottery paper for high-end applications, etc., hot paper can be seen in more and more places. Use of sensitive paper. [0003] When printing on thermal paper, you need to use the matching thermal printer. The working principle of the thermal printer is: the printing head of the thermal printer is equipped with a heating element. When the heating element passes a certain current, it will quickly generate high temperature. When the top coat of the paper meets the hea...
