The carbon tapes obtained in examples 1 to 5 and comparative examples 1 to 6 were used to produce a standard sample by using a commercially available printer (105 SL manufactured by Zebra Co.). The thickness measurement was performed using a thickness tester (DAVLSC 0PE FMP 30) which was automatically recorded by pressing the FINAL-RES key.
As can be seen from the results of table 1: the Braille book made of the carbon ribbon which can be used for making Braille books needs to be identified in hand feeling, so that the transferred raised particles need to be identified by touch with a certain thickness, and the mass ratio of the TPU resin to the sodium bicarbonate in the microcapsule is 1: when the thickness of the convex particles is 0.3-0.6, the thickness of the convex particles is 7-9 microns, and the sensing degree is good. In addition, the adhesive layer has certain friction resistance after transfer printing, so that the durability of the braille characters can be enhanced.

the bonding layer is composed of the following raw materials in percentage by weight: 10-30% of water-based acrylic resin, 10-30% of aldehyde ketone resin, 0.2-0.5% of base material wetting agent, 0.1-0.3% of defoaming agent, 5-15% of carbon black, 15-35% of ethanol and 15-35% of deionized water;
the carbon ribbon is additionally provided with a foaming layer containing foaming microcapsules, sodium bicarbonate in the foaming microcapsules is decomposed and foamed in the transfer printing process, and the printing material has a raised granular feeling and Braille hand feeling identifiability.
2. The carbon ribbon for braille book production according to claim 1, characterized in that the high-speed shearing and emulsifying machine has a rotation speed of 800-1000 rpm.
3. The method for preparing a carbon ribbon for braille book production of any one of claims 1 to 2, characterized by comprising the steps of:
1) coating a back coating on one surface of the base material, and drying;
2) coating a foaming layer on the other surface of the base material in an amount of 2.0 to 4.0g/m2Drying at 40-80 ℃ and entering the next working procedure;
3) coating an adhesive layer on the surface of the foaming layer, wherein the coating weight is 0.5-1.5 g/m2And drying at 40-80 ℃ to obtain the carbon ribbon.
