The invention discloses a modified black talc antibacterial material as well as a dry preparation process and application thereof. According to the dry-method preparation process, a modifying agent is dropwise added to activated black talc and then dried to prepare the modified black talc antibacterial material, and the modifying agent is prepared by neutralizing a silane coupling agent with a silver nitrate solution and fully stirring and reacting. The modified black talc antibacterial material is prepared by adopting the dry preparation process of the modified black talc antibacterial material. The invention also discloses an application of the modified black talc antibacterial material in plastics. Silver ions are uniformly dispersed and fixed on the surface of black talc through the linking effect of the silane coupling agent KH-550, clustering of the silver ions is effectively prevented, material discoloration is prevented, and the antibacterial performance is excellent; and the silane coupling agent gre
