Embodiment 1

[0046] Preparation of silicone-modified water-based polyurethane dispersion: Add polyethylene glycol (molecular weight 1000) and sandan oil into a three-necked flask at a molar ratio of 2:1, raise the temperature to 100°C, remove the water in the system by vacuuming, and cool down Standby; add 222g IPDI into an empty three-necked flask, start stirring, and heat up to 70°C; then add 370g of the dried mixture of the above-mentioned polyethylene glycol and sandan oil to IPDI, after 30min dropwise, continue the reaction, and add Add 100ml methyl ethyl ketone to the system and react at 70°C for 2.5h to generate a prepolymer with -NCO terminal group; measure the value of -NCO to meet the requirements.

[0047] According to the molar ratio of unreacted NCO to N-methyldiethanolamine in the reaction system is 4:1, N-methyldiethanolamine is added dropwise, and the chain extension reaction is continued at 70°C for 2 hours to obtain cationic end-NCO polyurethane; detect NCO After reaching...

Abstract

The invention provides a water-based nail polish. The water-based nail polish includes silicone-modified water-based polyurethane dispersion, water-based acrylic emulsion, coalescent and water. The components of the water-based nail polish provided by the present invention include silicone-modified water-based polyurethane dispersion, water-based acrylic emulsion, film-forming aids and water. Silicone-modified water-based polyurethane dispersion and water-based acrylic emulsion are used as film-forming bodies, endowing the nail polish with good film-forming properties, and the cured nail film has high strength. In particular, the use of silicone-modified water-based polyurethane dispersions can significantly improve the peelability and scratch resistance of nail polish after film formation. At the same time, with the addition of film-forming aids, the water-based nail polish in the present invention has both excellent moldability, peelable, matte and scratch-resistant properties.

Description

technical field [0001] The invention relates to the technical field of organic materials, in particular to a water-based nail polish. Background technique [0002] Regardless of the cultural atmosphere, everyone has a love for beauty, and people's pursuit of beauty has never stopped. Beauty, hairdressing, manicure, dressing and dressing are all pennies and bucks. When fashion becomes popular, nail art becomes an essential skill for beauty lovers. However, traditional nail polish contains a large amount of organic solvents, which are harmful to the human body. And the traditional nail polish is mostly UV curable nail polish. Although it has the characteristics of high fullness and strong adhesion, it has two major defects at the same time: first, use organic solvents to clean the nails when removing the nails, which will damage the nails and fingers and cause long-term damage. Time use can easily lead to nail problems; second, a specific light source is required for curing...
