Abstract

The invention relates to an antibacterial material, as well as a preparation method and application thereof. The antibacterial material comprises a carrier, an inorganic bacteriostatic agent and an organic bacteriostatic agent, wherein the carrier comprises montmorillonite, the granularity of the inorganic bacteriostatic agent is 1-50 nm. The antibacterial material provided by the invention is rapid in interaction speed, excellent in antibacterial effect and long in effective acting time and cannot loss the antibacterial activity due to the dissolution and loss.

Description

technical field [0001] The invention belongs to the technical field of bacteriostatic materials, in particular, relates to bacteriostatic materials and their preparation methods and applications, more specifically, to bacteriostatic materials and their preparation methods, and bacteriostatic plastics. Background technique [0002] At present, there are many antibacterial materials used in the market, and various antibacterial materials have different performances due to different preparation methods and processes. Generally speaking, there are few materials with stable chemical properties, no toxic effects on the human body, no harm to the environment, no secondary pollution, and low manufacturing costs. Commonly used disinfection and sterilization methods such as spray disinfection using hydrogen peroxide, peracetic acid, etc. as disinfectants, ultraviolet disinfection, ozone disinfection, etc., are widely used in terminal disinfection. Once the disinfection factors are rem...
