Problems solved by technology

[0003] At present, domestic photosensitive resins used for nail polish are single in variety and monotonous in color, mainly in light colors such as colorless, transparent, light yellow or white.
The black photosensitive resin mainly adopts the color paste containing carbon black. The absorption of carbon black to ultraviolet rays is concentrated in the range of 180~260nm. exposure requirements
There are many UV-curable nail polish products on the market, but the price is relatively high, and the flexibility is poor, which can easily lead to brittle nails

Abstract

The invention discloses an environment-friendly and light cured nail enamel with high dispersibility and a preparation method thereof. The nail enamel is prepared from the following raw materials in parts by weight: 55 to 65 parts of polyurethane acrylate, 18 to 22 parts of epoxy acrylate, 6 to 8 parts of 1,6-hexanediol diacrylate, 14 to 18 parts of light cured color paste, 3 to 5 parts of 2-methyl-1-(4-methylmercaptophenyl)-2-morpholine-1-actone, 3 to 5 parts of photo-initiator, and 2 to 4 parts of leveling agent. The prepared light cured color paste is in a liquid state, contains graphene, can be conveniently mixed with light sensitive resin, and barely affects the light curing speed. A black nail enamel is obtained. The color paste can be well dispersed in the nail enamel and has a certain modifying effect on resin. The obtained nail enamel has a proper adhesion force, can be well adhered on nails, and can also be easily peeled off from nails. People can remove the nail enamel without using an organic solvent, the harm to the nails is avoided, and the nail enamel is environment-friendly. The coating of the nail enamel is flexible.

Description

technical field [0001] The invention belongs to the field of nail polish materials, and in particular relates to a highly dispersible and environment-friendly photocurable nail polish and a preparation method thereof. Background technique [0002] Nail polish is basically made of nitrocellulose with chemical solvents such as acetone, ethyl acetate, ethyl lactate, and tincture of phthalic acid. The nail polish is applied on the nails, which can make the nails red and moist, and does not fade for a long time, so it is loved by people. Ordinary nail polish is a nail film-forming agent in which ester-soluble nitrocellulose is dissolved in a certain highly active ester-based solvent system. % of nitrocellulose, a small amount of oily solvents, camphor, titanium dioxide, and oil-soluble pigments. The film formed after the nail polish is applied to the nails is firm and has a moderately colored luster, which can protect the nails and give them a sense of beauty. . [0003] At p...
