Abstract

The invention discloses a carbon ribbon which can be used for making Braille books and a preparation method. , from the inside to the outside of the base material, the foam layer and the adhesive layer are sequentially formed, and the foam layer is composed of the following raw materials by weight: 20~40% of foamed microcapsules, 15~35% of water-based wax emulsion , Substrate wetting agent 0.2~0.5%, defoamer 0.1~0.3%, ethanol 15~35% and deionized water 15~35%. The innovation of the present invention is that a foamed layer containing foamed microcapsules is added to the carbon ribbon. During the transfer process, the sodium bicarbonate in the foamed microcapsules is decomposed and foamed, and a raised grainy feeling will appear on the printing material, with Braille characters. The hand feel is recognizable, printing is faster and scannable, the internal paper requirements for Braille books are not high, and the selection of materials is wider, which reduces the production cost of Braille books.

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...
