Compared with the prior art, the present disclosure has the following beneficial effects.
The technical schemes of the present disclosure are clearly and completely described below in conjunction with specific embodiments. Apparently, the embodiments described are merely a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without making creative effort are within the protection scope of the present disclosure.
In a first aspect of the present disclosure, a nail polish glue is provided. The nail polish glue includes the following components in parts by weight: 15-57 parts of an acrylate prepolymer, 20-52 parts of an acrylate active monomer, 5-10 parts of a photoinitiator, 5-10 parts of mercaptan, 5-10 parts of an additive, and 3-8 parts of a colorant.
The nail polish glue of the present disclosure has low odor and environmental friendliness, is convenient to operate and package. For example, unified packaging of multiple colors or multiple bottles of the glue in an eyeshadow plate can be used. The nail polish glue is solid, and mixing by flowing of the glue cannot be caused. The nail polish glue has a high curing speed, good adhesion, a high gloss and other characteristics. Although being solid, the glue can recover a good leveling property without a brushmark after being applied, can be completely cured after irradiation under a 36 W UV/LED lamp for 60 seconds, and has a mirror leveling effect. A cured film has adhesion on nails, wear resistance, chemical resistance, and high gloss and color retention.
In one of the embodiments, a nail polish glue is provided. The nail polish glue includes the following components in parts by weight: 20-50 parts of an acrylate prepolymer, 25-45 parts of an acrylate active monomer, 6-8 parts of a photoinitiator, 6-8 parts of mercaptan, 6-8 parts of an additive, and 4-6 parts of a colorant.
Further preferably, a nail polish glue is provided. The nail polish glue includes the following components in parts by weight: 25-35 parts of an acrylate prepolymer, 30-40 parts of an acrylate active monomer, 6-8 parts of a photoinitiator, 6-8 parts of mercaptan, 6-8 parts of an additive, and 4-6 parts of a colorant.
In one of the embodiments, the acrylate prepolymer is a composition of more than one or two of polyurethane acrylate, pure acrylate, or polyester acrylate.
Since a molecule of the polyurethane acrylate contains an acrylic functional group and a carbamate bond, a cured adhesive has high wear resistance, adhesion, flexibility, high peeling strength and excellent low temperature resistance of polyurethane and excellent optical properties and weather resistance of polyacrylate. The polyurethane acrylate contains many polar groups such as an ester group and amino, and can achieve a hydrogen bonding effect with an anti-settling agent, namely fumed silica, so that the thixotropy of a system is improved. In addition, a short-chain ternary alcohol is used to replace a part of diols, so that the synthesized polyurethane acrylate has a rigid branched structure, a high curing rate, high hardness, and better adhesion.
The polyester acrylate has the excellent properties of low odor, low irritation, high reactivity, good flexibility and pigment wettability. A carboxyl contained can achieve a hydrogen bonding effect with the anti-settling agent, namely fumed silica, so that the thixotropy of the system is improved.
Further preferably, the polyurethane acrylate is aliphatic carbamate acrylate.
In one of the embodiments, the acrylate active monomer is a composition of more than one or two of hydroxyethyl methacrylate, acryloyl morpholine, isobornyl acrylate, dipropylene glycol diacrylate, 1,6-hexadiol diacrylate, or cyclic trimethylopropane formal acrylate.
The acrylate active monomer mainly has the effects of realizing dilution, increasing the crosslinking density and increasing the reaction speed.
In one of the embodiments, the photoinitiator is a composition of more than one or two of acylphosphorus oxide, 1-benzoylcyclohexanol, 2-methyl-1-(4-methylthiophenyl)-2-morpholine-1-acetone, or ethyl (2,4,6-trimethylbenzoyl)phenylphosphinate.
The photoinitiator is excited by ultraviolet light to produce free radicals, instantly resulting in a crosslinking reaction of the acrylate prepolymer and the acrylate active monomer, and the curing speed is increased.
In one of the embodiments, the mercaptan is a composition of more than one or two of pentaerythritol tetra(3-mercaptopropionate), trimethylolpropane tris(3-mercaptopropionate), or 1,4-butanediol di(3-mercaptopropionate).
The nail polish glue is affected by oxygen inhibition in a curing process, so that the curing time is prolonged. The mercaptan has the effects of resisting oxygen inhibition and promoting surface curing, so that the phenomenon of oxygen inhibition can be effectively eliminated.
In one of the embodiments, the additive is a composition of more than one or two of an anti-settling agent, a dispersing agent, a leveling agent, a thickening agent, a defoaming agent, microcrystalline cellulose, or microcrystalline wax.
The anti-settling agent is used as a rheological control agent of a coating material, so that the coating material has thixotropy and greatly improved viscosity. Fumed silica is used as the anti-settling agent.
The dispersing agent can be used for improving the gloss of the nail polish glue, improving the tinctorial strength and hiding power, improving the coloring strength and toning property, preventing a floating color and a drifting color of the nail polish glue, and preventing flocculation and settlement. By adding the dispersing agent, the tinctorial strength, rheological property, stability and other properties of pigment particles in a dispersion system can be significantly improved. One of polyether modified siloxane or a polymer copolymer containing a pigment affinity group is selected as the dispersing agent.
By adding the leveling agent, the surface tension of the nail polish glue can be significantly reduced, the wetting ability and fluidity of the nail polish glue are improved, phenomena of a floating color and a flower-like color are effectively reduced, and properties such as leveling property, smoothness, shrinkage hole resistance, wear resistance, scratch resistance and peeling resistance of the nail polish glue can also be improved, so that the nail polish glue has a mirror leveling effect after curing. Glide 450 or Glide 410 of Tego of Germany is used as the leveling agent.
In one of the embodiments, the colorant is a composition of more than one or two of CI 77491, CI 77492, CI 77510, CI 77891, CI 77289, or CI 77266. Due to the colorant, the nail polish glue can have different colors, so that different needs of different users are met.
The present disclosure further provides a preparation method of any one of the nail polish glues. The method includes the following preparation steps:
In one of the embodiments, in step S1, the heating is conducted at a temperature of 45-60° C., and the stirring is conducted at a rotation speed of 500-800 r/min for 10-20 minutes.
In one of the embodiments, in step S2, the stirring for dispersion is conducted at a rotation speed of 1,000-1,500 r/min, for 60-80 minutes.
