The invention discloses a method for preparing a sterilizing and self-cleaning dining table and belongs to the technical field of dining tables. According to the method, an antibacterial
active ingredient, i.e., tea polyphenols is extracted from
green tea leaves and serves as a natural
antibacterial agent, nano-titania with
photocatalytic degradation action serves as a self-cleaning material, rich amino groups, which are produced by biological
nitrogen fixation of soybean
rhizobia, are used for carrying out
surface modification on the titania so as to increase surface hydrophilic groups of the titania and enable the modified titania to have an oleophobic effect, a
coating material is prepared through compounding the
antibacterial agent, the self-cleaning filler and a fluorinated pre-
emulsion, the surface of a dining table substrate is coated with the
coating material, then, natural air-
drying is carried out, and thus the sterilizing and self-cleaning dining table can be prepared. A
coating of the dining table prepared by the method has an oleophobic property, so that oil stains hardly remain after wiping, an antibacterial and self-cleaning effect can be achieved under the
photocatalysis of the titania and the antibacterial performance of the tea polyphenols, the problem that ordinary dining tables are prone to oil
stain remaining and bacterium propagating is effectively solved, the safety of eating of eaters is guaranteed, and thus the application prospect is broad.
