Problems solved by technology

There are many reports on nano-inorganic antibacterial agents, most of which are loaded on inorganic carrier materials (such as molecular sieves, montmorillonite, calcium carbonate, etc.) with nano-scale silver, zinc, copper, rare earth elements, etc. The disadvantage is that the carrier materials have no antibacterial properties and are effective in antibacterial Less ingredients, large amount of antibacterial agent; in the patent CH1341358A, a kind of antibacterial agent composed of water-based amino acid silver, amino acid zinc and its decomposition generated nano-metal silver and nano-zinc oxide as the main material is disclosed

Abstract

An inorganic nano-bacterial agent is prepared from nano-zinc oxide and water-soluble metal salt through chemical coposition, washing, drying and calcining.

Description

1. Technical field: [0001] The invention discloses a nano inorganic antibacterial agent and a preparation method thereof, belonging to the technical field of nano materials, and in particular relates to a nano inorganic antibacterial agent mainly composed of nano zinc oxide and a preparation method thereof. 2. Background technology [0002] As we all know, harmful bacteria are an important factor that causes human diseases and affects health. Therefore, how to eliminate and suppress harmful bacteria has been one of the focuses of scientists from all over the world since the discovery of bacteria. With the continuous development of science and technology, various antibacterial materials emerge in endlessly, which can be roughly divided into inorganic antibacterial agents and organic antibacterial agents. Most of the traditional inorganic antibacterial agents are toxic or corrosive, and their stability is poor, which limits the use of inorganic antibacterial agents. use. Org...
