The invention provides a color coated steel plate with antibacterial function, which is characterized in that base paint and finish paint contain antibacterial agent, and the antibacterial agent is silver-carrying titanium dioxide antibacterial agent. The production process performs the preprocessing and the distributed processing to the antibacterial agent, thereby leading the color coated steel plate to obtain the best antibacterial property. Meanwhile, the baking temperature control in the production process is very important, if the temperature is overhigh, the antibacterial agent is oxidized to lose the antibacterial effect; and if the temperature is overlow, the paint is not dried. The speed of a machine set is controlled for mainly stabilizing the range of the finish paint film thickness and obtaining favorable coating property and surface quality, which can be changed according to the equipment condition of a special machine set. Meanwhile, the color coated steel plate with antibacterial function fully meets the requirement of a user and the national standard, and provides multiple functions for the user.
