preparation example Construction

[0050] Preparation of lubricating layer:

[0051] Mix and stir the modified water-based silicone resin and water evenly to obtain a lubricating layer slurry (in terms of mass ratio, modified water-based silicone resin: water = 3:7), and then use a gravure coater to coat one side of the film The lubricating layer slurry is dried at 120°C, and the coating amount is controlled at 0.1g / m 2 ;

[0052] Preparation of thermosensitive dye layer:

[0053] The binder and sensitizer in the heat-sensitive dye layer are dissolved in a mixed solvent of toluene and methyl ethyl ketone, and at the same time, the method of heating to 65°C is used to assist the dissolution. After the dissolution is complete, the heat-sensitive dye and filler are added after cooling, and the high-speed Disperse evenly to obtain the heat-sensitive fuel layer slurry; in which, in terms of mass ratio, toluene: methyl ethyl ketone: solid material (each material in the heat-sensitive dye layer) = 4:3:3, and then us...

Abstract

The invention tries to solve the problems existing in the existing heat-sensitive paper printing through a film coating technology; the invention provides coated heat-sensitive paper and a processingtechnology thereof. The coated heat-sensitive paper comprises a paper base and a heat-sensitive color developing agent layer, and further comprises a film layer, one side of the film layer is coated with a heat-sensitive dye layer, the other side of the film layer is coated with a lubricating layer, and the film layer is compounded on the surface of the paper base in the mode that the heat-sensitive dye layer faces the heat-sensitive color developing agent layer through a film coating process. Compared with existing heat-sensitive paper, the coated heat-sensitive paper shows higher smoothness,scratch resistance, physical and chemical corrosion resistance, weather resistance and durability and smaller thermal damage, is non-toxic and dust-free, and avoids potential safety hazards to humanhealth.

Description

technical field [0001] The invention belongs to the technical field of thermal transfer printing and film coating, and in particular relates to a film-coated heat-sensitive paper and a processing technology thereof. Background technique [0002] Today's world is in the information age, the amount of human information is increasing rapidly, and the information to be processed is increasing day by day, which requires matching means such as rapid recording, storage, retrieval and analysis. Therefore, information recording materials are particularly important. Materials such as thermal paper, digital photography, photosensitive resins, and laser recording flourished. Due to the thermal recording method has the characteristics of no smoke, no noise, high resolution, color copying, and easy operation. With the development of computer terminal technology and printing equipment technology, thermal recording has gradually replaced other traditional methods. Such as electrocardiogra...
