Problems solved by technology

[0003] Traditional inkjet paints and nail polish inkjet paints are noisy during operation, and paint atomization pollutes the air; there are many preparation procedures before spraying, the operation is complicated and easy to mix colors, clog the nozzles, and it is difficult to clean the air gun when changing colors; inkjet printing skills are not easy to master; air pump Occupies space, many supporting tools, difficult to maintain
At the same time, the drying speed of traditional inkjet paint is slow, and the surface drying time of flat color film with normal thickness is 2-4 days, and generally contains volatile solvents
Improper dilution of nail polish inkjet paint can easily lead to false colors, color glue spots, etc.

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.

Abstract

The invention discloses an utraviolet curing fingernail pigment and a preparation method thereof, relating to the field of production of pigments. The utraviolet curing fingernail pigment comprises the following raw materials in parts by weight: 55-75 parts of acrylic oligomer, 15-25 parts of acrylate monomer, 1-10 parts of a photoinitiator, 0.1-1 part of a flatting agent, 0.1-0.5 part of a defoamer, 1-10 parts of a thickener, 0.1-3 parts of a dispersing agent, 0.1-0.5 part of a wetting agent, and 1-10 parts of a pigment body. The utraviolet curing fingernail pigment has the viscosity greater than 30Pa.s, has high thixotropy, and can not flow when in a stationary state; an air gun is not used, thin coatings and gradient ramp coatings can be directly drawn on the surface of the fingernail, and then by matching a coloring pen, the drawing effect the same as that formed by jet drawing of the pigment by using the air gun is achieved, and further, the problem that the patterns drawn by using the coloring pen have sags and crests and are uneven in color in the existing pigment jet drawing method is solved.

Description

technical field [0001] The invention relates to the field of pigment production, in particular to an ultraviolet curing nail pigment and a preparation method thereof. Background technique [0002] At present, the society mainly adopts inkjet painting to lightly coat the nail surface and paint with gradient colors. The products on the market are mainly traditional inkjet paint and nail polish inkjet paint. The traditional inkjet paint is powered by an air pump to drive the air gun to spray the inkjet paint on the nail surface to make the nail surface colored, and the gradual color is drawn on the nail surface through the slow movement of the air gun. The nail polish inkjet paint is powered by an air pump to drive the air gun to spray the diluted nail polish inkjet paint on the nail surface to make the nail surface colored, and at the same time, the air gun moves slowly to draw a gradient color on the nail surface . [0003] Traditional inkjet paints and nail polish inkjet p...
