Problems solved by technology

In this regard, at present, most of them improve the light quantum efficiency, increase the oxidation ability, and expand the spectral absorption range by modifying zinc oxide. However, the photocatalytic ability of nano-zinc oxide obtained by this method is still limited, especially at night when there is no light, because it cannot absorb light. The energy of light prevents it from exerting its antibacterial properties

Abstract

The invention discloses an antibacterial plastic master batch, a preparation method thereof and antibacterial plastic. The antibacterial plastic master batch comprises the following raw material components in parts by weight: 15-40 parts of nano zinc oxide, 1-15 parts of nano silver powder, 1-15 parts of nano copper powder, 0.5-5 parts of graphene, 5-25 parts of a long afterglow luminescent material, 1-6 parts of a dispersing agent, 0.1-5 parts of a coupling agent and 30-70 parts of carrier resin. The antibacterial component in the antibacterial plastic master batch takes the nano zinc oxide as a substrate, and the nano silver powder, the nano copper powder, the graphene and the long afterglow luminescent material are added in an auxiliary manner, so that the antibacterial plastic master batch can play an antibacterial role in a relatively wide wavelength range, and also can play an antibacterial role in the absence of illumination.
