High-adhesion wear-resistant UV-LED ink and preparation method thereof

[0023] A preparation method of high adhesion wear-resistant UV-LED ink, comprising the following steps:

[0024] S1, prepare each component by weight part in Table 1;

[0025] S2. Add high-functionality urethane acrylate, adhesion promoter, cyclopentene ethyl isocyanurate triacrylate, and photoinitiator into the reaction kettle in sequence for mixing and stirring. The stirring speed is 800r / min, and the stirring time is 15 minutes. ;

[0026] S3, then add fillers and additives for mixing and stirring, the stirring speed is 800r / min, and the stirring time is 30 minutes;

[0027] S4. Carry out sufficient grinding on a three-roll machine until the ink fineness is below 5 microns.

[0029] S1, prepare each component by weight part in Table 1;

[0030] S2. Add high-functionality urethane acrylate, adhesion promoter, cyclopentene ethyl isocyanurate triacrylate, and photoinitiator into the reaction kettle in sequence for mixing and stirring. The stirring speed is 1000r / min, and the stirring time is 10 minutes. ;

[0031] S3, then add fillers and additives for mixing and stirring, the stirring speed is 1000r / min, and the stirring time is 15 minutes;

[0032] S4. Carry out sufficient grinding on a three-roll machine until the ink fineness is below 5 microns.

[0034] S1, prepare each component by weight part in Table 1;

[0035] S2. Add high-functionality urethane acrylate, adhesion promoter, cyclopentene ethyl isocyanurate triacrylate, and photoinitiator into the reaction kettle in sequence for mixing and stirring, the stirring speed is 1200r / min, and the stirring time is 20 minutes ;

[0036] S3, then add fillers and additives for mixing and stirring, the stirring speed is 1200r / min, and the stirring time is 25 minutes;

[0037] S4. Carry out sufficient grinding on a three-roll machine until the ink fineness is below 5 microns.
