[0079] Preparation of UV curable resin A:

[0080] UV curable resin A-1:

[0081] Add 320g of polytetrahydrofuran ether diol into a four-necked flask equipped with mechanical stirring, a thermometer and a vacuum device, dehydrate at 112°C and a vacuum of 0.88MPa for 1.5h; cool down the dehydrated polytetrahydrofuran ether diol to 78°C, add 40g of isophorone diisocyanate and 0.5g of bismuth isooctanoate into a four-necked flask, control the temperature at 78°C, and after 2 hours of reaction, cool down to 72°C, add 23g of capping agent hydroxyethyl acrylate to In the four-necked flask, the temperature was controlled at 72°C, and the reaction was stopped when the NCO value dropped below 0.02%, to obtain UV curable resin A-1 with a functionality of 2.

[0082] UV curable resin A-2:

[0083]Add 270g of polypropylene glycol polyether diol into a four-necked flask equipped with mechanical stirring, a thermometer and a vacuum device, and dehydrate for 1 hour at 115°C and a vacuum of...

[0093] The preparation of photocurable light-changing nail polish, formula is as shown in table 1 (weight part), and its preparation method comprises the following steps:

[0094] (1) Add the photoinitiator and polymerization inhibitor into the diluted monomer according to the ratio of ingredients, stir at 500r / min for 10min, dissolve and mix evenly;

[0095] (2) Under the condition of stirring, add UV curable resin A and UV curable resin B, stir at 1000r / min for 30min until uniformly mixed, continue to add rheology modifier, stir for 30min until uniformly mixed, then add optical variable pigment and Ordinary pigments, stirred for 30 minutes until uniformly mixed, filtered, and discharged to obtain the light-curable light-varying nail polish.

Abstract

The invention provides ultra-violet curing optically variable nail polish. The nail polish includes a: 30-70 parts by weight of UV cured resin A; b: 10-30 parts by weight of UV cured resin B; c: 10-50 parts by weight of diluted monomer; d: 0.1-10 parts by weight of a photoinitiator; e: 0.01-5 parts by weight of a polymerization inhibitor; f: 0.01-5 parts by weight of a rheolobic modifier; g: 0.1-15 parts by weight of optically variable pigments; and h: 0.1-10 parts by weight of common pigments. The nail polish can make nails show different colors when the nails are observed at different angles; and the nail polish has the effects of gorgeous color, high color saturation, simple operation, excellent adherence, high brightness and good endurance.

Description

technical field [0001] The invention relates to the technical field of nail paints, in particular to an ultraviolet light-curable light-changing nail polish and a preparation method thereof. Background technique [0002] At present, the nail polishes used by people are divided into solvent-based nail polish, water-based nail polish and UV light-curable nail polish. Among them, light-curable nail polish has become one of the main products widely used in the nail art market today. Nail polish can not match the high gloss and colorful color, and it has better durability, easy operation and more convenience than conventional nail polish. [0003] In order to make the nail polish more colorful, produce different decorative effects, and increase the color richness of the nail polish, color-changing nail polish came into being. The early color-changing nail polish mostly used the method of adding fluorescent dyes to the nail polish, which can produce fluorescent effects under the ...
