Abstract

The invention discloses a preparation method for inorganic antibiosis, and particularly relates to a preparation method for inorganic antibiosis with copper ion containing silver and a preparation method for inorganic antibacterial agent with copper ion containing silver, ZrOCl2 8H2O, NaH2PO4 2H2O and Na2C2O4 are mixed to form solution and are reacted to synthetize Na0.64H0.36Zr2(PO4)3 H2O, and is respectively reacted with Cu(NO3)2 and AgNO3. The preparation methods provided by the invention have the functions that: firstly, Cu<2+> is reacted and converted, secondly, Ag<+> is reacted and converted, the antibacterial activity of inorganic antibiosis with copper ion containing silver is enabled to be the same, the introduction amount of Ag<+> is reduced, and the consumption of silver is lowered, the cost of raw materials is obviously lowered, and the stability is greatly increased, meanwhile, since the introduction amount of Cu<2+> is not large, the surface is prevented from changing into a black color caused by oxidization into CuO, and the appearance and the introduction range are also prevented from being affected; additionally, the variation original nature of inorganic antibiosis with copper ion containing silver prepared by the invention is negative, stimulation to skin is zero, and high safety is realized.

Description

technical field [0001] The invention relates to a preparation method of inorganic antibacterial agents, in particular to a preparation method of silver-containing copper ion inorganic antibacterial agents and a preparation method of silver-containing copper ion inorganic antibacterial agents. Background technique [0002] Antibacterial agents can be divided into three categories: natural, organic and inorganic according to their ingredients. Natural antibacterial agents are mainly natural plant extracts with limited resources; organic antibacterial agents have been used for decades; inorganic antibacterial powders started relatively late, commercialized in developed countries in the 1980s, while my country started in the 1990s In the middle and late stages, there are fewer product types and smaller scales. Inorganic antibacterial agents can be divided into two categories according to their mechanism of action on microorganisms: one is photocatalytic semiconductor materials; ...
