Summary of the invention

The present invention has solved the sun-proof poor performance of existing nial polish, and the ultraviolet radiation preventing poor performance especially to the technical problem of the ultraviolet absorption ability difference in UVA district, provides a kind of nial polish with better sun-proof result.

The present invention has also solved the firmness of existing nial polish and the technical problem of glossiness difference, and a kind of nial polish with good gloss degree and firmness is provided.

The present invention has adopted unique formula, and its proportioning of mainly preparing burden (percentage by weight) is:

Ethyl acetate: 10%～30%; Butyl acetate: 20%～40%; NC Nitroncellulose (1/2S): 10%～20%; Sunscreen: 1%～8%; Amino resins: 15%～35%; Camphora: 1%～5%; As preferably, the charge ratio of described sun-proof nial polish (percentage by weight) is:

Ethyl acetate: 18%～23%; Butyl acetate: 26%～33%; NC Nitroncellulose (1/2S): 12%～16%; Sunscreen: 4%～6%; Amino resins: 25%～32%; Camphora: 2%～4%;

Ethyl acetate among the present invention and butyl acetate are used for dissolving materials such as NC Nitroncellulose as a kind of blended active solvent.This combination liquid of preparation by a certain percentage has suitable volatility, has improved on the one hand the rate of drying of nial polish, can not influence dressing effect on the other hand, promptly can not form striped because of drying too quickly makes on the nial polish coating.NC Nitroncellulose in the component can form one deck primary membrane as a kind of film former, and its viscosity number has guaranteed that also nial polish has suitable flowability.Also contain a kind of amino resins and Camphora among the present invention, wherein Camphora uses as plasticizer.The adding of amino resins can reduce the hardness of cellulose membrane, strengthens adhesive force and pliability, provide a kind of have flexible, the nial polish with good gloss and plasticity.

Wavelength is that the light radiation of 280-400nm can make human epidermal become sepia, and particularly wavelength is that the UV-B light of 280-320nm can cause that erythema and sunburn appear in skin, thereby wants this UV-B light of filtering.Wavelength is that the UV-A light of 320-400nm can cause skin aging, causes the damage of skin elasticity and wrinkle occurs, even become the root of phototoxic reaction, therefore also wishes filtering UV-A light.Many sunscreen are invalid to UV-A, and UV-A is the immediate cause that causes the melanoma skin cancer, and in addition, therefore the inductive erythema of UV-A energy Enhanced UV-B prevents that comprehensively ultraviolet radiation is particularly important.

The sunscreen that the present invention uses is 4-methoxy cinnamic acid-2-Octyl Nitrite and 2,2 '-methylene-two-6-(2H-benzotriazole-2 base)-4-(tetramethyl-butyl)-1,1,3,3-phenol sunscreen.Wherein 2,2 '-methylene-two-6-(2H-benzotriazole-2 base)-4-(tetramethyl-butyl)-1,1,3,3-phenol is benzotriazole derivatives, and as the UV-AB all band sunscreen of a new generation, it has the double performance of organic sunscreen agent and inorganic sunscreen, combine the special ultraviolet (UV)-AB scattering and the reflectance signature of the strong absorption feature and the inorganic sunscreen of typical organic matter, have two kinds of traditional UV-A, the effect of UV-B Ultraviolet rays protection.And itself is highly stable to light, is a kind of very effective sunscreen.
