Problems solved by technology

[0003] Graphene is a honeycomb planar film formed by carbon atoms in the form of Sp2 hybridization. It is a quasi-two-dimensional material with only one atomic layer thickness, so it is also called monoatomic layer graphite. Graphene can destroy the integrity of cell membranes , causing the destruction of the bacterial structure and the disorder of the function; but the antibacterial effect of graphene is poor, and the cell membrane of some bacteria is damaged, but the cells can still work normally, so that after using the antibacterial liquid, bacterial growth occurs, which in turn affects the antibacterial liquid. use

Abstract

The invention discloses a durable graphene antivirus antibacterial liquid and a preparation method thereof. The antibacterial liquid is prepared from the following raw materials in parts by weight: 3-8 parts of graphene oxide, 10-15 parts of an antibacterial synergist, 3.5-5 parts of sodium dodecyl benzene sulfonate, 3-5 parts of an emulsifier, 1-3 parts of glycerol, 1-3 parts of propylene glycol and 80-100 parts of water. The antibacterial synergist is prepared in the process of preparing the antibacterial liquid, the antibacterial synergist can act with a head group of acidic phospholipid in a bacterial cell membrane, so the infiltration capacity of the cell membrane is reduced, bacterial cell sap leaks, and bacterial cells die; meanwhile, the synergist can be combined with a Q0 site of cytochrome b in bacterial mitochondria, and electron transfer between the cytochrome b and the cytochrome c1 is blocked, so mitochondrial respiration is inhibited, mitochondria cannot supply energy required by normal metabolism of cells, and sterilization is more thorough.

Description

technical field [0001] The invention relates to the technical field of bactericide preparation, in particular to a durable graphene antivirus and antibacterial liquid and a preparation method thereof. Background technique [0002] With social progress and economic development, people pay more attention to their own health. Two-thirds of the time is spent at home every day, and a clean and sterile home environment is particularly important, so the use of antibacterial solutions is widespread in thousands of households. The main components of antibacterial liquids currently on the market are p-chloro-m-xylenol or quaternary ammonium salts. These two types of reagents are toxic, and long-term use is not good for the environment and the human body. Therefore a kind of safety and environmental protection, the antibacterial liquid with broad-spectrum bacteriostasis effect is the demand of consumers in general. [0003] Graphene is a honeycomb planar film formed by carbon atoms i...
