Problems solved by technology

In the past, the back coating was mainly made of silicone, but the defect was the migration of silicone oil, which affected the printing of high-end products
In addition, most of the imported back coatings are products grafted with acrylic acid and silicone, which need high temperature curing, which wastes heat energy, and the cost of carbon tape will increase.
In addition, this kind of grafted product does not meet the heat resistance requirements for high-end products, and the carbon ribbon will be broken, so it cannot be applied to thermal sublimation at all.

Abstract

The invention discloses back coating liquid for a thermal transfer printing carbon ribbon and a thermal sublimation carbon ribbon and a preparation method thereof. An effective component of the back coating liquid is nitrocotton and the mass percent of the nitrocotton is 1 to 20 percent; specifically, the components are as follows in parts by weight: 2 to 15 parts of the nitrocotton, 1 to 10 partsof a lubricant, 77 to 98 parts of an organic solvent and 2 to 8 parts of an auxiliary agent. A carbon ribbon back coating is a place where a carbon ribbon is in direct contact with a printing head ofa printing machine. The back coating liquid has the effect that the printing head is protected in a carbon ribbon (at a wound state) unfolding process and excellent heat conductivity is provided, sothat ink can be transferred to a medium, and the formation of static electricity which is harmful to the printing machine and an operator of the printing machine is reduced, and furthermore, the service life of the protection head is prolonged.

Description

technical field [0001] The invention relates to the technical field of hot stamping, in particular to a back coating solution for thermal transfer carbon ribbons and thermal sublimation ribbons and a preparation method thereof. Background technique [0002] With the continuous expansion of the application of carbon belts, there are more and more varieties of carbon belts, which are more and more high-end. From wax base, hybrid base, resin base to sublimation ribbon and so on. The higher the carbon ribbon, the higher the requirements for the back coating. A layer of back coating on the back of the ribbon, its main function is to reduce the wear of the print head; reduce static electricity and enhance heat conduction. In the past, the back coating was mainly made of silicone, but the defect was the migration of silicone oil, which affected the printing of high-end products. In addition, most of the imported back coatings are products grafted with acrylic acid and silicone, ...
