Abstract

The invention discloses an antibacterial paint containing porous organisms and a preparation method thereof. The paint comprises porous organism powder, silver, and a titanium dioxide antibacterial material, wherein silver and the titanium dioxide antibacterial material are adhered on the porous organism powder. The paint is composed of following components in percentage by weight: 12.0 to 25.0 wt.% of silver nano powder, 18.0 to 32.0 wt.% of nano titanium dioxide, 28.0 to 58.0 wt.% of ultrafine porous organism powder, and 0 to 30.0 wt.% of other metal nano powder.

Description

technical field [0001] The invention belongs to the technical field of electronic coating materials and relates to an antibacterial coating material, in particular to an antibacterial coating containing porous organisms and a preparation method thereof. Background technique [0002] In people's actual life, the skin will inevitably come into contact with various bacteria, fungi and other microorganisms. These microorganisms will multiply rapidly under suitable external conditions, and spread diseases through contact and other ways, affecting people's bodies. healthy. The skin, in particular, is more susceptible to infection after trauma, burns, or ulcers, or slows wound healing. Objects that people often touch will not only absorb bacteria and other microorganisms on the surface of the object itself, but also cause the spread of bacteria through cross contact. If antibacterial materials are coated on the surface of the object, the surface of the object will have the functio...
