Preferably, the particle size of the nano titanium dioxide is 20-100 nm.
Preferably, the nano titanium dioxide is porous titanium dioxide.
Preferably, the porous titanium dioxide and the nano ultraviolet absorbent are uniformly mixed by a high-speed mixer, then the silver-loaded antibacterial agent, the dispersing agent and the carrier resin are added and uniformly stirred, and finally the antibacterial master batch is obtained by a color master batch machine. The porous titanium dioxide and the nano ultraviolet absorbent are uniformly mixed, so that the nano ultraviolet absorbent can be fully filled in the porous titanium dioxide.
Preferably, the nano ultraviolet absorbent is benzophenone ultraviolet absorbent, salicylate ultraviolet absorbent or benzotriazole ultraviolet absorbent.
The second purpose of the invention is to provide an antibacterial plastic.

The invention has the beneficial effects that:
the antibacterial master batch provided by the invention can slowly release a small amount of silver ions under a humid condition, and the silver ions with positive charges are adsorbed on the surface of bacteria due to the negative charges on the surface of the bacteria, so that the electrolyte balance of the bacteria is damaged, and the bacteria die due to the damaged cell walls. Meanwhile, silver ions can enter the interior of the bacteria to react and combine with cellular enzymes of the bacteria, so that the activity of the cellular enzymes and the reproduction and regeneration of the bacteria are inhibited, and the effect of killing the bacteria is achieved.
The antibacterial master batch can effectively sterilize the surface of the nano titanium dioxide through photocatalytic reaction under the action of ultraviolet rays under the irradiation of sunlight. Meanwhile, the nano titanium dioxide has small particle size and high activity, can absorb ultraviolet rays and scatter the ultraviolet rays, and the scattered ultraviolet rays can be further absorbed by the nano ultraviolet absorbent, so that the antibacterial master batch has good ultraviolet resistance.
The nano titanium dioxide adopts porous titanium dioxide, the porous titanium dioxide is filled with a nano ultraviolet absorbent to form a mixed structure, the exposed part of the titanium dioxide of the mixed structure mainly generates a photocatalytic reaction to play a role in sterilization, and the exposed nano ultraviolet absorbent of the mixed structure mainly plays a role in absorbing ultraviolet.
The antibacterial master batch has good antibacterial effect in both dark and humid environments and sunlight irradiation environments.
