Problems solved by technology
[0007]However, the ink head using the thermal bubble jet inkjet technology works in a high temperature and high pressure environment for a long time, the nozzle is easily corroded, and the ink solution is also easy to cause Problems such as ink splash and nozzle clogging
[0008] At present, although the above-mentioned defects can be optimized to a certain extent theoretically by changing the structure or improving the ink, the principle of inkjet printing determines that the above-mentioned problems cannot completely eradicated
[0009] In the prior art, there is also a type of printer that uses thermal printing or transfer printing. This type of printer does not have an inkjet nozzle structure and an inkjet process, although It avoids the problem of ink drying and clogging of the nozzle of inkjet printer, but because the principle of thermal printer is that the printing head is heated and contacts the thermal printing paper to realize the printing process, such printing process is to make the thermal paper chemically After the reaction, it sublimates and adheres to the substrate. Such a process will easily lead to poor printing effect, and it is easy to fade and fall off, thereby reducing the printing quality

preparation example Construction
[0060] The above-mentioned thermal vaporization carbon ribbon of the present invention can theoretically be prepared by any existing method for preparing a carbon ribbon; the present invention provides a specific preparation method, comprising the following steps:
[0061] 1) respectively configuring the solution of the gas-generating layer 3, the solution of the dye layer 4 and the solution of the fusible protective film 5;
[0062] 2) playing corona on both sides of the substrate 2;
[0063] 3) Coating the solution of the gas-generating layer 3 on one side of the substrate 2 and drying, the drying temperature is 60-120°C;
[0064] 4) Coating the solution of the dye layer 4 on the gas-generating layer 3 and drying, the drying temperature is 90-150°C;
[0065] 5) Coating the solution of the meltable protective film 5 on the dye layer 4 and drying it.
[0066] Before step 3), the back coat 1 is coated on the other side of the substrate 2.
[0067] The above-mentioned prepara...
Embodiment
[0073] In the thermal vaporization carbon ribbons in the following embodiments, the dye layer 4 is divided into three colors, namely red, yellow and blue, and the thermal vaporization carbon ribbons of the three colors have the same structure; wherein, the material of the substrate 2 is PET film .
[0074] In Examples 1-27, the solution preparation method of the back coating 1 is as follows: Weigh the raw materials according to the following parts: 100 parts of 2-butanone, 100 parts of toluene, 5 parts of polyurethane modified silicone resin, 5 parts of acrylic modified silicone resin 5 parts of resin, 2 parts of leveling agent, 2 parts of dispersant, 2 parts of antistatic agent.

Abstract
The invention relates to a thermal vaporizationthermal transfer ribbon, a preparation method and a printer. The thermal vaporizationthermal transfer ribbon comprises a base material, wherein a gas production layer, a dye layer and a fusible protective film are sequentially arranged at one side of the base material; the gas production layer can be heated to produce gas; and the fusible protective film can be heated to melt out spray holes for spraying out dye of the dye layer. The printer comprises a fixed-point heat production resistor and the thermal vaporizationthermal transfer ribbon, and the resistor can heat the thermal vaporization thermal transfer ribbon. By arranging the gas production layer, the dye layer and the fusible protective film, when the thermal vaporization thermal transfer ribbon is heated, the dye layer can be fused into the liquid dye to the sprayed out to realize printing, so that the printing form of an ink-jet printer is replaced, and the problems of nozzle blockage and cleaning of the ink-jet printer are solved.
Description
technical field [0001] The invention relates to the field of printers, in particular to a thermal vaporization carbon ribbon, a preparation method and a printer. Background technique [0002] Common types of printers in production and life mainly include inkjet, laser and thermal. In daily use, inkjet printers are used in a wide range of applications. [0003] At present, the inkjet printer market is mainly occupied by Epson, HP and Canon. Among the major brands of inkjet printers in the prior art, there are mainly two types of specific inkjet technologies: the micro piezoelectric technology represented by Epson, and the thermal technology represented by Canon's bubble type and HP's thermal technology. inkjet technology. [0004] The main principle of the micro-piezoelectric technology printer is to use the piezoelectric sheet to generate mechanical vibration, and complete the entire process of controlling the inkjet by the piezoelectric element through pressure, without ...
