Abstract

The invention discloses a carbon ribbon capable of being used for making books for the blind and a manufacturing method thereof. The carbon ribbon is composed of a base material as well as a back coating layer and a thermal transfer printing layer which are separately coated at the two sides of the base material, wherein the thermal transfer printing layer is divided into two layers, the surface of one side of the base material is sequentially provided with a foaming layer and a bonding layer from inside to outside; the foaming layer consists of the following raw materials in percentage by weight: 20-40% of foaming microcapsules, 15-35% of water-based wax emulsion, 0.2-0.5% of a base material wetting agent, 0.1-0.3% of a de-foaming agent, 15-35% of alcohol and 15-35% of deionized water. The innovation point of the carbon ribbon is that a foaming layer containing the foaming microcapsules is added into the carbon ribbon, and sodium bicarbonate in the foaming microcapsules is decomposedand formed in a transfer printing process, so that a raised particle feeling appears on a print material, and therefore, the carbon ribbon has braille hand feeling identifiability, is quicker in printing, can be scanned, is not high in requirements on sheets inside the books for the blind, is wider in material selection, and reduces manufacturing cost of the books for the blind.

Description

technical field [0001] The invention belongs to the technical field of hot stamping materials, and in particular relates to a carbon ribbon which can be used for making Braille books and a preparation method thereof. Background technique [0002] For the production of Braille books, the ratio of the total number of blind people in my country to the types of Braille publications per capita is about 60,000:1. However, the development of Braille publishing in China is extremely slow. In recent years, the vast majority of blind people desire to read books, increase their skills, and participate in society. However, the serious shortage of funds for Braille publishing and the limitations of the blind people's own economic conditions make it impossible for most blind people to realize this desire. This situation has greatly restricted the improvement of the overall cultural level of the blind, and the publication of Braille publications is limited by complex processing, high costs...
