The addition of nanometer accessory ingredient in the paint to improve the function of the traditional paint has been the hot topic in the field of anticorrosive paint research. In this paper, three kinds of water nanometer accessory ingredients including anti-abrasive cleaner, hydrophobing agent and anti-aging agent has been added into the paint to combine the nanometer denaturizing paint. The functions of nanometer denaturizing paint such as shellac’s adhesive force, resistance to water, resistance to alkali , and hydrophobic property were measured to evaluate the effect of the accessory ingredint according to the related test standard. It was found that the type and the quantity of nanometer accessory ingredient can effectively modify the function of the water paint. Finally, the optimum parameters were obtained.
