Disclosed is a method for manufacturing an electrically non-conductive black mirror comprising: preparing a base material; and spraying, onto the base material, simultaneously, a black mirror solution consisting of 0.08 to 0.2 wt% of nitric acid, 0.5 to 2 wt% of ammonia water with respect to a concentration of 30%, and the rest of water, and an aqueous reducing agent consisting of 0.1 to 3 wt% of a basic material, 0.1 to 2 wt% of sodium gluconate or glucose, 0.002 to 0.2 wt% of formalin, and the rest of water, to form an electrically non-conductive black mirror. According to the present invention, a black mirror can be easily manufactured by spraying the black mirror solution and the aqueous reducing agent simultaneously onto various base material including plastics, metals, glasses, etc. Furthermore, a black mirror manufactured by the method according to the present invention can provide an aesthetic design by presenting various colors in combination with the color of a base material, and has electrically non-conductive properties thereby preventing jamming of a mobile communication device, and damage to circuits of electric/electronic devices or malfunction thereof. Accordingly, a black mirror manufactured by the method according to the present invention can be applied to various products. |
