Embodiment 1

[0024] Acrylic emulsion 5g

[0025] Emulsified silicone oil 2 grams

[0026] Leveling agent 2 grams

[0027] water 91

[0028] Weigh 91 grams of water and add it to the mixing tank, then weigh 5 grams of acrylic emulsion (solid content 60%), slowly add water while stirring, stir evenly and completely dissolve, weigh 2 grams of emulsified silicone oil and 2 grams of leveling agent Add to a mixing tank and mix well. The whole process is carried out at room temperature.

[0029] The back coating solution is applied to thermal transfer printing and thermal sublimation carbon ribbons at 0.05-0.2 grams per square meter to meet the requirements of carbon ribbons for back coating. Heat resistance instantaneous temperature 260 degrees. Friction coefficient Kd<0.2. It is no problem to continuously print 30 rolls of 110X300m carbon ribbon with a Zebra 300dpi barcode printer at 14 degrees. No powder drop, no pollution to the print head.

Abstract

The invention discloses a water-soluble back coating solution for thermal transfer ribbons and a preparation method thereof. The effective ingredient of the water-soluble back coating solution is water-based resin emulsion having a mass percentage of 4-58 percent. The water-soluble back coating solution is specifically prepared from the following components in parts by weight: 5-48 parts of water-based resin emulsion, 1-10 parts of a lubricating agent, 1-8 parts of additives and 34-93 parts of a diluting agent. The ribbon back-coating layer is the position of a ribbon directly contacted with the printing head of a printer, and has the effects that the ribbon is used for protecting the printing head in an unfolding process (from a wound state) and providing excellent heat conductivity, inkcan be transferred to a medium, formation of static electricity harmful to the printer and printer operators can be reduced, and the service life of the printing head can be prolonged.

Description

technical field [0001] The invention relates to the technical field of hot stamping, in particular to a water-soluble back coating solution for thermal transfer carbon ribbons and a preparation method thereof. Background technique [0002] The existing carbon ribbon back coating in the market is solvent-based. Although everyone has solvent recovery equipment, it still pollutes the environment more or less, and still has VOC content. However, as the market becomes more and more stringent on environmental protection requirements, the current back coating fluid can no longer meet the environmental protection requirements. [0003] 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 ribb...
