Problems solved by technology

[0004] Silver-based zeolite inorganic antibacterial agent has high efficiency and safety, but it also has certain disadvantages: if it is not firmly loaded, it is not resistant to washing when it is used as a textile additive; the antibacterial range has certain limitations
But the disadvantage is that the bactericidal effect is limited when used alone

The invention is applied in the field of preparation of antibacterial products.

Description

technical field [0001] The invention relates to an antibacterial compound preparation containing silver and zinc ions and its application, in particular to an antibacterial compound preparation containing silver-loaded zinc nanometer zeolite and tourmaline and its application. Background technique [0002] At present, there are many applications and published documents and open patents on the market, and the better effects are as follows: [0003] 1. Silver zeolite inorganic antibacterial agent. The mechanism of silver-based inorganic antibacterial agents is: ① Inorganic antibacterial agents are mainly based on metal ions. Metal ions are positively charged. When trace amounts of metal ions contact the cell membrane of microorganisms, Coulomb attraction occurs with the negatively charged cell membrane. Metal ions penetrate the cell membrane and enter the bacteria to react with sulfhydryl groups and amino groups on proteins in the bacteria. The active center of the protein i...
