Embodiment 1

[0028] Embodiment 1: The visible light curable nail polish of the present invention uses an acrylate resin system as its components, camphorquinone as a visible light initiator, and organosilicon as a brightening agent. 95.5 wt% of pure acrylate resin, 2 wt% of camphorquinone, 0.5 wt% of organic silicon and 2 wt% of TMPTA were mixed and fed, and stirred at a speed of 1000 rpm in a mixer under normal temperature and pressure conditions to make it reach Dispersed phase, fineness up to 5 μm, can produce transparent glossy nail polish.

Embodiment 2

[0029] Example 2: 88 wt% polyurethane acrylate, 1 wt% titanocene, 1 wt% silicone, 5 wt% HDDA and 5 wt% permanent red were mixed and fed, and ground at normal temperature and pressure When its fineness reaches 3 μm, red visible light-curable nail polish can be produced.

Embodiment 3

[0030] Example 3: Using wt % epoxy resin, 10 wt % organic peroxide, 0.1 wt % brightener OD279, 10 wt % EHA and 10 wt % phthalocyanine blue, under normal temperature and pressure conditions, mix After stirring at a speed of 800 rpm, the fineness reaches 10 μm, and blue visible light-curable nail polish can be produced.

[0031]The nail polish raw material of the present invention is environmentally friendly, non-toxic, and has no irritating smell, and can be quickly dried in a visible light curing nail machine, and can also be naturally dried under the irradiation of sunlight. This avoids the ultraviolet light damage that may be caused by the use of ultraviolet curing in the existing nail art technology, and there is no need to worry about various health problems caused by inhalation or skin contact with harmful substances.

[0032] After drying, the nail polish is bright and shiny, and it is firmly attached to the nails, not easy to fall off, and will not dissolve in oil or dr...

Abstract

The invention belongs to the technical field of material chemistry, and particularly relates to visible light curing nail enamel and a preparation method thereof. The visible light curing nail enamel comprises the components: 2-98wt% of oligomer, 2-98% of reactive diluent, 0.01-10wt% of visible light initiating agent, 0.01-1wt% of brightening agent and 0-10wt% of pigment. The nail enamel can be cured under the irradiation of visible light with wavelength of 380-780nm, and the harm of ultraviolet light to the skin is avoided; the nail enamel can be rapidly dried in a visible light curing nail printer, and can also be slowly cured under the irradiation of sunlight or other common lighting sources. The visible light curing nail enamel is free of toxic organic solvent or film coalescing aid and safe to use, is guaranteed to be bright lastingly and not easy to drop after being dried, is insoluble in daily oil or water solutions, but can be removed by saline solution or sodium bicarbonate water solution without grinding, so that the harm to the nails is avoided, and the condition that the fine particulate matters are inhaled to affect the lung health is also avoided.

Description

technical field [0001] The invention belongs to the technical field of material chemistry, and in particular relates to a visible light-curable nail polish and a preparation method thereof. Background technique [0002] Nail polish, also known as "nail varnish", is a kind of makeup. It can form a thin film when applied on the nails. The color is bright and shiny, and it can give nails a sense of beauty, so it is widely loved by women. Bright and colorful nails are a must for beautiful women. [0003] Nail polish currently on the market can be divided into three main types: nitro nail polish, water-based nail polish and UV nail polish. [0004] Nitro nail polish, also known as chemical nail polish, is mainly based on nitrocellulose, coupled with chemical solvents such as acetone, ethyl acetate, ethyl lactate, and phthalates, as well as a small amount of camphor, titanium dioxide, and oil-soluble nail polish. Made of paint etc. A variety of organic solvents contained in thi...
