Problems solved by technology

However, its wear resistance and water resistance still need to be further improved.
[0004] At present, the water-based nail polish on the market still has the following disadvantages: the binding force between the water-based nail polish and the nail is insufficient, which will easily cause the nail polish on the edge of the nail to peel easily and affect the appearance

Abstract

The invention provides bio-based water-based light-cured nail polish and a preparation method thereof. The bio-based water-based light-cured nail polish comprises bio-based water-based polyurethane emulsion and auxiliaries, the bio-based waterborne polyurethane emulsion is prepared from the following preparation raw materials in percentage by weight: 0-15% of polyester polyol or polyether polyol,5-15% of bio-based polyol, 5-10% of diisocyanate, 0.01-0.02% of a catalyst, 0.5-1% of a carboxyl or sulfonic group-containing hydrophilic chain extender, 0.4-0.8% of an alcohol chain extender, 0.1-1%of an end capping agent, 0.3-0.8% of a neutralizer, 25-40% of a solvent, 0.1-2% of acrylate, 0.005-0.01% of a water-based photoinitiator and 35-45% of deionized water. The auxiliaries comprise an adhesion promoter, a leveling agent, a wetting agent, a thickener, pearlescent and / or color paste, a brightener and a flavoring agent. By adding the bio-based water-based polyurethane emulsion and the adhesion promoter, the prepared bio-based water-based light-cured nail polish has the characteristics of good wear resistance, good water resistance and strong adhesion.

Description

Technical field[0001]The present invention relates to an aqueous referral oil, and more particularly to a biological aquiferous photocurable nail polish and a preparation method thereof.Background technique[0002]Nail polish is used to modify and increase nail cosmetics, and the role of protecting the nails by forming a layer of friction-resistant film on the surface of the nail. Nail polish is mainly composed of two parts: a part is a pigment, a pigment or a flash material, or the like; a portion is a film formulation and a solvent. Conventional solvent-based nail polish, use some organic solvents, including acetone, ethyl acetate, phthalate, formaldehyde, etc. to cause nail polish to form a film and dry. However, these organic solvents are directly in contact with human nails or skin, which will affect human health and pollute the environment. In addition, solvent-based nail polish causes nails to dry, yellowing, brittle, and is not suitable for long-term use and repeated use. Ther...
