Examples
Embodiment 1
[0027] According to parts by weight, stir 1-10 parts of photoinitiator and 15-25 parts of acrylate monomer at a speed of 1000-2000r / min for 15-20min, dissolve and mix evenly; under stirring condition, add 55-75 1 part of acrylate oligomer, 0.1~3 parts of dispersant, and then stir at 1000~2000r / min for 20~25min to mix evenly; continue to add 0.1~0.5 part of wetting agent, 0.1~1 part of leveling agent, and stir for 20~ Mix evenly for 25 minutes; further add 1-10 parts of pigment, 1-10 parts of thickener, 0.1-0.5 parts of defoamer, stir and mix, grind the resulting mixture until the particle size is less than 20 microns, and filter to obtain UV-curable nail pigment.
Embodiment 2
[0029] In parts by weight, 4.5 parts of 2,4,6-trimethylbenzoyl-diphenylphosphine oxide, 2 parts of 1-hydroxycyclohexyl phenyl ketone, 15 parts of difunctional acrylate, 3 parts of tetrafunctional Stir methacrylate at a speed of 1500r / min for 18min, dissolve and mix evenly; under stirring conditions, add 65.2 parts of urethane acrylate and 0.5 part of Disperbyk-168 to the above mixed solution, and then stir at a speed of 1500r / min for 25min to mix evenly; Continue to add 0.3 parts of WET270, 0.2 parts containing molecular structure R(OC 3 h 5 ) b (OC 2 h 4 ) a Oh 5 C 3 (Me 2 SiO) n SiMe-leveling agent, stir for 20 minutes to mix evenly; further add 3 parts of red pigment, 5 parts of bentonite, 0.3 parts containing molecular structure -O(SiMe 2 O) X SiMe 2- the antifoaming agent is stirred and mixed, the resulting mixture is ground to a particle size of less than 20 microns, and filtered to obtain an ultraviolet curable nail pigment.
Embodiment 3
[0031] In parts by weight, stir 5 parts of bis-2,6-difluoro-3-pyrrolephenyl titanocene and 15 parts of tetrafunctional acrylate at a speed of 2000r / min for 15min, dissolve and mix evenly; Add 60 parts of polyester acrylate and 0.5 parts of Disperbyk-108 into the liquid, and then stir at 2000r / min for 20 minutes to mix evenly; continue to add 0.5 parts of BYK-168, 0.2 parts containing molecular structure R(OC 3 h 5 ) b (OC 2 h 4 ) a Oh 5 C 3 (Me 2 SiO) n SiMe-leveling agent, stir for 20 minutes to mix evenly; further add 5 parts into black pigment, 6 parts of fumed silica, 0.3 parts containing molecular structure-O(SiMe 2 O) X SiMe 2 - the antifoaming agent is stirred and mixed, the resulting mixture is ground to a particle size of less than 20 microns, and filtered to obtain an ultraviolet curable nail pigment.
