[0039] 2) Then, add 0.5-2 parts of vinyl monomers containing active hydrogen for capping, react for 0.5-1 hour, then cool the system temperature to 30-50°C, then add 1.3-3.2 parts of volatile base, and And react for 20-30 minutes, then add 60-100 parts of water, stir and disperse at high speed for 10-30 minutes, then raise the temperature to 70-90°C;

[0040] 3) Finally, at a temperature of 70-90°C, add an initiator solution (0.2-0.8 parts of initiator dissolved in 10-40 parts ...

Embodiment 1

[0044] 1) First, add 4 parts of methyl methacrylate, 9.9 parts of polycaprolactone diol, 8.5 parts of isophorone diisocyanate, 0.8 parts of 1,4-butanediol, 1.66 parts of dihydroxy Methylpropionic acid, 0.15 parts of trimethylolpropane and 0.01 part of catalyst dibutyltin dilaurate, the reaction temperature is 70 ° C, and the reaction time is 1 hour;

[0045] 2) Then, add 0.5 parts of hydroxyethyl acrylate for capping, react for 0.5 hours, then cool the system temperature to 30°C, then add 1.3 parts of ammonia water, neutralize and react for 20 minutes, then add 60 parts of water, stir and disperse at high speed 10 minutes, then heat up to 80°C;

[0046] 3) Finally, at a temperature of 80°C, add hydrogen peroxide solution (0.2 parts of initiator dissolved in 10 parts of water) to the reactor and drop it evenly into the reactor within 1 hour. After the addition is completed, continue to keep warm React for 1 hour to obtain an aqueous polyurethane emulsion;

[0047] 4) Add BYK-...

Embodiment 2

[0049] 1) First, add 4 parts of methyl acrylate and 5 parts of butyl acrylate, 11.5 parts of polycarbonate diol, 10.1 parts of hexamethylene diisocyanate, 1.3 parts of diethylene glycol chain extender into the dry reactor , 2.16 parts of dimethylolbutyric acid, 0.22 parts of glucose and 0.05 part of catalyst dibutyltin diacetate, the reaction temperature is 80 ° C, and the reaction time is 2.5 hours;

[0050]2) Then, add 1.2 parts of hydroxypropyl acrylate for capping, react for 0.6 hours, then cool the system temperature to 40°C, then add 1.9 parts of triethylamine, neutralize for 25 minutes, then add 75 parts of water, high-speed Stir and disperse for 20 minutes, then raise the temperature to 70°C;

[0051] 3) Finally, under the condition that the temperature is 70°C, add potassium persulfate solution (0.4 parts of initiator dissolved in 21 parts of water) to the reactor and drop it evenly into the reactor within 2 hours. After the dropwise addition, Continue the heat prese...

Abstract

The invention discloses an environment-friendly water-based nail polish and a preparation method thereof. The nail polish includes aqueous polyurethane emulsion, defoamer, accelerator, thickener and pigment. The water-based polyurethane emulsion is made of the following components by weight: 4-18 parts of inert vinyl monomer, 9.48-13.35 parts of polymer polyol, 8.5-14 parts of diisocyanate compound, 0.8-2 parts of chain extender, 1.66-1 2.95 parts of hydrophilic chain extender, 0.15-0.3 parts of cross-linking agent and 0-0.095 parts of catalyst, 0.5-2 parts of vinyl monomer containing active hydrogen, 1.3-3.2 parts of volatile base, 60-100 parts of water and The initiator solution is prepared by dissolving 0.2-0.8 parts of initiator in 10-40 parts of water. The preparation process of the water-based nail polish of the present invention is simple, environment-friendly and pollution-free, and embodies the performances of being green, environment-friendly, non-toxic and tasteless.

Description

technical field [0001] The invention relates to a nail polish, in particular to an environment-friendly water-based nail polish and a preparation method thereof. Background technique [0002] Nail varnishes in use today are almost all manufactured based on binders containing organic solvents. Nail polishes produced by major international companies in the market are almost all composed of nitrocellulose, modified resins, and various mixed solvents. However, the solvents that can dissolve nitrocellulose are generally esters, ketones, benzenes, alcohols, etc. Ether and other volatile, irritating and toxic organic solvents can affect human health and cause environmental pollution. Therefore, reducing or even completely avoiding organic solvent components in conventional nail polishes has attracted great interest. Contents of the invention [0003] The object of the present invention is to overcome the problems of polluting the environment and harming human health existing in ...
