Abstract

The invention discloses LED UV-cured black ink, which comprises, by weight, 20 to 40 parts of self-extinction light-cured resin, 15 to 35 parts of acrylic acid modified rosin resin, 5 to 15 parts of UV monofunctional monomer, 5 to 20 parts of UV multifunctional monomer, 1 to 10 parts of photoinitiator, 0.5 to 8 parts of photochromic pigment, 5 to 20 parts of inorganic black pigment, 3 to 15 partsof light guide powder, 0.5 to 5 parts of carbon black, 0.05 to 0.5 part of leveling agent and 0.05 to 0.5 part of defoamer. According to the LED UV-cured black ink, an LED UV curing technology is creatively adopted, photochromism and light guide technologies are combined, a wet film is formed after a base material is coated with the black ink with high covering power, the same curing efficiency ofthe wet film from the surface to the bottom is achieved through LED UV light curing, and a coating formed after curing meets the performance requirement of thermocuring ink.

Description

technical field

[0001] The invention relates to the field of inks, in particular to a black ink cured by LED UV. In addition, the present invention also relates to a preparation method and application of the black ink cured by LED UV. Background technique

[0002] As the screen-to-body ratio of mobile phones and other electronic products is getting higher and higher, the frame is getting smaller and smaller. Therefore, the shading effect of the shading ink coated on the frame is also getting higher and higher. After the shading ink is coated The formed coating should not only be light and thin, but also need to have high hiding power. Under normal circumstances, the shading ink of the 3C industry frame is basically a black ink with high hiding power. In order to solve the problem of high hiding power of the black ink on the frame, the traditional shading ink has a high content of carbon black in the black ink, and some inks have a carbon black content as high as 10%. There...
