Nano-siller antibiotic composition

Abstract

The nanometer silver antiseptic mixture consists of nanometer silver solution, water emulsion type polyurethane resin PU-50, Nivelon, penetrant m-1038C and water mixed together. The nanometer silver antiseptic mixture is prepared into spraying agent sprayed to the surface of object, and may be adhered firmly to maintain the nanometer silver ion for long term and result in lasting sterilizing effect. It may be used for car, bus, hotel, hospital, household, etc.

Description

technical field [0001] The invention belongs to a nano-silver antibacterial preparation, in particular to an antibacterial mixture containing a nano-silver solution. Background technique [0002] The particle size of the nano-silver particle is between 1-100 nanometers, and the nano-silver has a bactericidal effect. Nano-silver particles continuously release silver ions, and silver ions inhibit the reproduction of bacteria through the following three ways: 1. Silver ions attack the -SH group in the metabolic enzymes inside the bacteria, making the metabolic enzymes of bacteria inactive, hindering Normal metabolism of bacteria; 2. Silver ions react with the peptidoglycan exposed on the bacterial cell wall, making it impossible to transfer energy into the cell, hindering the normal physiological activities of bacteria; 3. Changes in the combination of silver ions and bacterial DNA alkaline bases It disrupts bacterial DNA structure and inhibits DNA transcription. Through the ...

Problems solved by technology

[0007] However, the adhesion of nano-silver to objects is not strong, and it is difficult to play a bactericidal and antibacterial effect on the surface of objects for a long time.
