Abstract

The invention relates to the technical field of antibiosis, in particular to a plastic antibacterial agent as well as a preparation method and application thereof. The nano-silver antibacterial agent disclosed by the invention is prepared by loading silver ions on zirconium phosphate exchange, and is compounded with nano-zinc oxide, so that the nano-silver antibacterial agent has broad-spectrum antibacterial property. The invention relates to a superfine powder with uniform granularity, which has extremely low hygroscopicity and high heat resistance and can be easily mixed and processed in fibers, films and plastic resin molded products. The physical and chemical properties are very stable, and the dyeing resistance and the discoloration resistance are excellent in the processing process and the using process. The product has very high safety and passes multiple environmental protection safety tests.

Description

technical field [0001] The invention relates to the field of antibacterial technology, in particular to a plastic antibacterial agent, a preparation method and an application thereof. Background technique [0002] Antibacterial agents refer to a class of agents used to prevent and control plant diseases caused by various pathogenic microorganisms. Agents that can kill or inhibit the growth of pathogenic microorganisms without hindering the normal growth of plants. Fungicides can be classified according to their mode of action, source of raw materials, and chemical composition. Internationally, it is usually used as a general term for agents to prevent and control various pathogenic microorganisms. With the development of fungicides, subclasses such as bactericides, virucides, and algicides are distinguished. [0003] Antibacterial agents are generally divided into inorganic antibacterial agents, organic antibacterial agents and natural antibacterial agents. Inorganic ant...
