The invention provides an aqueous antibacterial polymer emulsion and a coating combination. The aqueous antibacterial polymer emulsion comprises a polymer A, an oxidizing agent and a metal complexing with a copolymer B. Wherein, the copolymer B comprises a monomer containing heterocycle; the metal is selected from copper, silver, tin, zinc and its combination; the emulsion enables a stabilization of heat and/or light. The coating combination prepared by the antibacterial polymer emulsion provides a long-lasting antibacterial activity with wide spectrum, and has no color changing problem under the blazing sunlight and/o the heat. |
