Problems solved by technology

However, water-based nail polish uses resins such as water-based polyurethane or water-based acrylic acid as an adhesive, and water as a solvent, which has the disadvantage of slow drying at room temperature. Some formulas still contain nitrocellulose, which is not truly environmentally friendly and non-toxic. Containing alcohol ester twelve as film-forming aids, antifreeze agents such as ethylene glycol and propylene glycol, these ingredients pose a threat to life, health and the environment; commercially available UV nail polish refers to UV-curable nail polish containing active diluents, although not Contains organic solvents, but the main component prepolymer has a relatively high viscosity, and a reactive diluent must be used to adjust the viscosity, especially the commonly used acrylic ester reactive diluents have a strong stimulating effect and carcinogenicity. During the preparation process and drying hazards to human health

Abstract

The invention relates to a preparation method of biobased water-borne UV (ultraviolet) curing environment-friendly nail polish. The preparation method is characterized by comprising the following steps of weighing 30 to 50% of biobased water-borne UV curing environment-friendly nail polish resin, 5 to 10% of deionized water, 40 to 60% of pigment, 0.1 to 0.5% of wetting dispersant, 0.1 to 0.5% of flatting agent, 0.2 to 0.5% of defoaming agent, and 1.0 to 2.0% of thickener; adding the pigment, the wetting dispersant, the flatting agent, the defoaming agent and the deionized water into a ball mill to mill, so as to obtain a color paste a; adding the biobased water-borne UV curing environment-friendly nail polish resin into the color paste a, stirring at high speed, adding the thickener, and filtering by a 200-mesh filter net, so as to obtain the biobased water-borne UV curing environment-friendly nail polish. The prepared biobased water-borne UV curing environment-friendly nail polish has the characteristics that the curing speed is quick, the transparency is good, the storage stability and luster are high, the adhesion force is good, and the like. The preparation method has the advantages that the green, environment-friendly, non-toxic and non-odor effects are realized, and the product cost is reduced.

Description

technical field [0001] The invention relates to the technical field of material chemistry, in particular to a preparation method of a bio-based water-based UV curing environment-friendly nail polish resin. Background technique [0002] As a kind of make-up, nail polish can form a film on the nails with bright color and give the nails a sense of beauty. There are two types of environmentally friendly nail polishes on the market today: water-based nail polish and UV nail polish. Although these two kinds of nitro nail polishes contain a large amount of esters, ketones, alcohol ethers and other volatile organic solvents in the early stage, compared with nitrocellulose modified resins as binders, they have no organic solvents, such as ethyl acetate, etc. , reducing the harm to nails and the human body, and environmental pollution. However, water-based nail polish uses resins such as water-based polyurethane or water-based acrylic acid as an adhesive, and water as a solvent, whi...
