Embodiment

[0050] Prepare the white neutral ink of embodiment and comparative example according to the component shown in table 1 and proportioning, then carry out performance test to the prepared white neutral ink, test data is as shown in table 1, during performance test, viscosity is in Tested on Brookfield DV2T; surface tension is tested on Sigma 702ET; hardness is tested by standard pencil hardness tester; scratch resistance is tested by nail visual test; adhesion is tested by standard 100-grid method. ABS and other materials; the fluency test is to print on the car stickers and check the number of mouths.

[0051] The white neutral ink for UV-LED inkjet printing prepared by the present invention can be printed on leather, PC, TPU, PMMA, ABS and other materials, and has a wide range of applications. In the printer of the nozzle, it is then spray printed on the substrate. After the ink passes through the nozzle of the printer, it can be cured on the substrate in time. It is convenien...

Abstract

The invention discloses white neutral ink for UV-LED ink-jet printing and a preparation method thereof. The white neutral ink for UV-LED ink-jet printing is prepared from the following components and a formula: 2 to 15 weight percent of resin, 55 to 70 weight percent of a diluting monomer A, 10 to 25 weight percent of UV nano color paste, 5 to 15 weight percent of a photoinitiator and 0.1 to 5 weight percent of an auxiliary agent, wherein the sum of the percentages of the components is 100 percent; at least one of the resin, the diluting monomer A and the UV nano color paste has an amide group. The white neutral ink is green, environment-friendly, good in adhesive force and wide in substrate application range, can be applied to substrates such as soft materials such as leather and TPU and hard materials such as PC, ABS and PMMA, does not crack after being repeatedly bent, is adjustable in hardness, has both flexibility and hardness, also has the excellent characteristics of good smoothness, low viscosity, scratch resistance, high covering degree and the like, and is excellent in comprehensive performance.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to a white neutral ink for UV-LED inkjet printing and a preparation method thereof, belonging to the technical field of ink. Background technique [0002] In today's society, with more and more outdoor advertisements, smart devices are printed and decorated by inkjet printing to meet individual needs. White ink is the most used inkjet ink. As a primer layer, the performance of the white ink directly affects the performance of the entire printing film. [0003] In traditional white ink, flexibility and hardness are contradictory. Soft ink has good flexibility but not enough hardness. Hard ink has high hardness but poor flexibility. Neutral ink has both hardness and flexibility. However, the domestic white neutral inks currently on the market are widely added to potentially carcinogenic monomers such as N-vinylpyrrolidone (NVP) or low-boiling volatile monomers such as dimet...
