It is added in sand mill after the mixing of body powder until being ground to partial size≤5 μm, obtains ink one;By ground ink one high speed
Coating machine is coated on band primary surface, and drying forms high temperature chromatograph, controls 7 μm of coating thickness, enters subsequent processing;
B) hydrogenated rosin resin and paraffin are melted, the carbon black of corresponding amount is then added under agitation, high-speed stirred 20 is divided
Clock is rolled with three-roller to fineness≤5 μm to mix acquisition mixture, by mixture, obtains ink two;Simultaneously by the heating of ink two
It is coated on high-temperature color layer surface, is cooled into low temperature chromatograph, 4 μm of control coating thickness secondary can make to get 23 μm of overall thickness
Heat transfer colour ribbon.
Specifically, the solvent is mixed with butanone by the toluene that volume ratio is 1:1 and is formed, and solvent usage is in step a)
7 times of phenolic resin weight.
Compared to the prior art, the beneficial effect comprise that:
1) heat transfer colour ribbon that the present invention secondary can use is using high temperature, the secondary coating of low temperature chromatograph, and the product of formation is in difference
Print temperature under, high temperature, low temperature chromatograph transfer twice, and a roll of colour band can realize the effect used twice, reduce use at
This, reduces waste yield, overcomes tradition and be only capable of expendable limitation;
2) traditional heat transfer colour ribbon product, in thermoprint transfer printing image-text be it is disposable, the scratch tape after using gives up as dangerous
Object needs high temperature incineration to dispose.Heat transfer colour ribbon of the present invention is due to being coated with high temperature, low temperature two layers of coatings, it is possible to use
Twice, using effect is 2 times of traditional colour band, while the hazardous waste generated is the half of traditional colour band, be can produce biggish
Economic benefit and environmental benefit.
