Heat transfer carbon ribbon and preparation method thereof

Abstract

The invention provides a heat transfer printing carbon ribbon. The heat transfer printing carbon ribbon is composed of a base ribbon, a back coating and a heat transfer layer, wherein the back coatingand the heat transfer layer are coated on the two sides of the base ribbon respectively; the heat transfer layer is divided into two parts, and an ink layer and a surface coating are sequentially arranged on the surface of one side of the base ribbon from inside to outside. The preparation method of the heat transfer printing carbon ribbon comprises the following steps of coating one side of thebase ribbon with the ink layer, wherein the coating amount is 1.5-3.5 g / m<2>, and drying; coating the surface coating on the surface of the ink layer, wherein the coating amount is 0.5-0.9 g / m<2>, anddrying; and coating the back coating on the other surface of the base ribbon coated with the ink layer and the surface coating, and drying to obtain the carbon ribbon. According to the heat transferprinting carbon ribbon and the preparation method thereof, the adhesiveness between the printing ink and a printing material is improved, so that the transfer printing effect is improved, the raw materials adopted in the carbon ribbon formula meet the low-carbon and environmental-friendly concept, and the expansion of the carbon ribbon using field is facilitated.

Description

technical field [0001] The invention relates to the technical field of heat transfer consumables, in particular to a heat transfer carbon ribbon and a preparation method thereof. Background technique [0002] Thermal transfer printing is the process of using heat and pressure to transfer ink from ribbon media to paper or film, transferring the ink to the label as it passes through the printer's printhead and platen. [0003] Thermal transfer printing technology is to use a special carbon ribbon to transfer the toner coating on the carbon ribbon to paper or other types of materials through the working principle similar to the print head of a fax machine. The coating material on the belt can be selected according to the needs to produce strong adhesion, coupled with the selection of printing media, it can ensure that the printed handwriting will not be affected by the outside world. And this heating process, how to heat, can be handed over to the computer to control. At prese...

Problems solved by technology

[0004] The carbon ribbons currently used in the thermal transfer printing industry will release a large amount of toxic organic substances during the preparation process. These substances not only pollute the environment, damage human health, but also pose fire hazards during production, transportation and storage.
