The invention discloses deodorizing antibacterial low-temperature archaized glaze and a preparation method thereof. The preparation method comprises the following steps: Step A, preparing a deodorizing antibacterial low-temperature frit; Step B, preparing glaze slip: mixing the low-temperature frit, a colouring agent, potash feldspar, quartz, calcite, talcum, calcium phosphate, a deodorant and an antibacterial compound to obtain mixed powder, adding sodium tripolyphosphate and carboxymethyl cellulose into the mixed powder and uniformly mixing, grinding and adding water so as to obtain the glaze slip; and Step C, uniformly applying the glaze slip onto a green body, putting the green body into a reducing atmosphere furnace, carrying out thermal insulation and naturally cooling to room temperature so as to obtain the deodorizing antibacterial low-temperature archaized glaze. In comparison with existing archaized glaze, the manufactured archaized glaze in the invention has advantages of scientific batching, reasonable preparation, pure color and stable performance, and also has lasting antibacterial property, antifouling self-cleaning function and deodorizing property. According to the invention, the application range of the archaized glaze is further widened.
