Problems solved by technology

Cu ions will affect the expressiveness of the product because of its own color. Silver is limited in its application range due to its easy oxidation and discoloration, high price, and easy agglomeration.
[0009] Because the antibacterial ability of metallic zinc itself is 1 / 1000 of that of metallic silver, most research institutions and manufacturers focus on the research and development of modification of Ag and nano-silver to improve their performance as an antibacterial agent, thus ignoring zinc. Many advantages as an antimicrobial agent, but little research has been done on it

Abstract

The invention relates to a nano-zinc antibacterial compound and its preparation method and application. The nano-zinc antibacterial compound of the present invention has outstanding characteristics such as high stability (non-oxidative, non-discoloration, non-toxic, odorless), low dose, high antibacterial efficiency, safety and non-toxicity, long antibacterial time, easy and safe operation, etc., especially can be compared It is easily dispersed in the corresponding products, which greatly enriches the application range, simplifies the operation procedures, and makes the practicability stronger.

Description

Technical field [0001] The present invention relates to antibacterial agents, and more particularly to nano-zinc antibacterial composites. In addition, the present invention also relates to a method for preparing the nano-zinc antibacterial compound and the application of the nano-zinc antibacterial compound. Background technique [0002] Microorganisms are a large group of organisms, including bacteria, viruses, fungi, and some small protists, microalgae, etc. They are small and closely related to humans. Covers many types of beneficial and harmful, covering food, medicine, industry and agriculture, environmental protection and many other fields. [0003] Bacteria that can cause human, animal and plant diseases are called pathogens. These microorganisms can multiply rapidly under suitable humidity and temperature, spread diseases through contact, and affect people's physical and mental health. Therefore, it is of great significance to study antibacterial agents that can be used...
