ABSTRACT:
In a method of preparing a non-toxic anti-tacky water paint, nitrocellulose is solubilized in n-butyl acetate to form a nitrocellulose solution, which is then mixed with urea-formaldehyde and water to form a first mixture solution, which is then heated for two to three hours via water at a temperature of 65 to 90° C. so that the first mixture solution is separated into an upper layer of liquid and a lower layer of powder. Next, the upper layer is removed, and ethylene glycol monobutyl ether is added to the lower layer to form a second mixture solution. Then, a non-ionic surfactant is added to the second mixture solution to form a third mixture solution. Finally, the third mixture solution is added to a water-soluble paint to obtain the non-toxic anti-tacky water paint, which may be coated on a container object so that the object can be conveniently transported and stored.
