Patent ID: 7857902

Claim:
A method of preparing a non-toxic anti-tacky water paint, the method comprising the steps of: solubilizing nitrocellulose ranging from 30 wt % to 40 wt % in n-butyl acetate ranging from 60 wt % to 70 wt % to form a nitrocellulose solution; mixing the nitrocellulose solution with urea-formaldehyde (UF) and water to form a first mixture solution, and heating the first mixture solution via water for 2 to 3 hours at a temperature ranging from 65 to 90° C. to separate the first mixture solution into upper and lower layers, wherein the lower layer is precipitated powder, and the upper layer is liquid; removing the upper layer of liquid, and adding ethylene glycol monobutyl ether, which has a volume greater than or equal to two times of a volume of the powder, to the lower layer of powder to form a second mixture solution; adding a non-ionic surfactant to the second mixture solution to form a third mixture solution; and adding the third mixture solution ranging from 3 wt % to 15 wt % to a water-soluble paint to obtain the anti-tacky water paint.
