The good carbon tape can protect the printing head, the produced effect can be accurately attached to the paper, the diffusion is not easy, and the falling is not easy. With the continuous development of carbon tape and printer technology, carbon tape is increasingly used, and white carbon tape is required on some colored or black substrates. In the prior art, the white carbon tape has insufficient covering power, cannot completely cover the color of the printing substrate, and has insufficient adhesion performance to the printing substrate, so that improvement is needed.
Disclosure of Invention
Aiming at the defects of insufficient covering power, insufficient adhesion performance and the like in the prior art, the utility model provides a novel white carbon tape.
In order to solve the technical problems, the utility model is realized by the following technical scheme:

The back coating is a coating coated on the back of the carbon tape and has the main effects of reducing the abrasion of a printing head, reducing static electricity and enhancing heat conduction. The release layer is primarily used to make the printed surface smoother and more consistent release of ink from the substrate. The first white ink layer and the second white ink layer are used for improving the covering power performance of the carbon ribbon. The back adhesive layer is used for enhancing the adhesion performance of the carbon tape to the printing substrate. According to the utility model, through the superposition design of the first white ink layer and the second white ink layer, the covering power of the carbon tape is effectively enhanced, and the defect of insufficient adhesion performance of the carbon tape to a printing substrate is overcome through the design of the back adhesive layer.
Preferably, in the white carbon tape, the base material layer is a PET film having a thickness of 4 μm to 5. Mu.m.
The design ensures that the performance of the substrate layer is more stable, improves the applicability and reduces the cost.
Preferably, in the white carbon ribbon, the back coating is made of modified silicone resin, and the thickness of the back coating is greater than 0.1 μm and less than or equal to 1 μm.
The modified organic silicon resin material has excellent heat resistance, so that the problem that the ribbon is sticky or wrinkled due to heating of the ribbon is avoided when the ribbon is subjected to thermal transfer printing.
Preferably, in the white carbon ribbon, the thickness of the release layer is greater than 0.1 μm and less than or equal to 1 μm, and the release material of the release layer is polyethylene wax.
The release layer further smoothes the printed surface by the design described above, allowing for a more consistent release of ink from the substrate.
Preferably, in the white carbon ribbon, the thickness of the first white ink layer is 1 μm to 3 μm, and the volume concentration of the white ink pigment used for the first white ink layer is 80% to 90%.
The content of titanium dioxide in the white ink is the most important factor for determining the covering power, and the covering power of the white ink can be improved by improving the pigment volume ratio of the titanium dioxide of the white ink, so that the covering power of a carbon belt is improved.
Preferably, in the white carbon ribbon, the thickness of the second white ink layer is 1 μm to 2 μm, and the volume concentration of the white ink pigment used for the second white ink layer is 70% to 80%.
The second white ink layer further improves the covering power of the carbon ribbon, simultaneously improves the problem of uneven surface during printing of the first white ink layer, and improves the evenness of the surface of the carbon ribbon.
Preferably, in the white carbon tape, the backing layer is made of one or two or three of acrylic resin, polyester resin and polyurethane resin.
The white ink pigment volume concentrations used for the first white ink layer and the second white ink layer are relatively high, so that the resin content in the first white ink layer and the second white ink layer is relatively low, which results in insufficient adhesion to the printing substrate. The back adhesive layer is made of resin, so that the adhesion performance of the carbon tape to the printing base material is effectively enhanced.
