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

A preparation method of bio-based water-based UV curing environment-friendly nail polish, by weighing 30-50% of bio-based water-based UV curing environment-friendly nail polish resin, 5-10% of deionized water, 40-60% of pigment, moistening Wet dispersant 0.1-0.5%, leveling agent 0.1-0.5%, defoamer 0.2-0.5% and thickener 1.0-2.0%; add pigment, wetting and dispersing agent, leveling agent, defoamer to the ball mill Grind with deionized water to obtain color paste a; add bio-based water-based UV curing environmentally friendly nail polish resin to color paste a, add thickener after high-speed stirring, and filter through a 200-mesh filter to obtain bio-based water-based UV curing environmental protection nail polish. The nail polish prepared by the invention has the characteristics of fast curing speed, good transparency, storage stability, high gloss, good adhesion, etc. The method of the invention is green, environmentally friendly, non-toxic and tasteless, and reduces product cost.

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...
