Polyhexamethylene guanidine silver ion composite disinfectant

Abstract

The invention relates to a polyhexamethylene guanidine silver ion composite disinfectant, which comprises a water-soluble silver salt, polyhexamethylene guanidine hydrochloride and an anti-tarnish factor, wherein in the composite disinfectant, the concentration of the water-soluble silver salt is 5 mg / L to 50 mg / L, the concentration of the polyhexamethylene guanidine hydrochloride is 0.5 g / L to 5 g / L, the concentration of the anti-tarnish factor is 100 mg / L to 500 mg / L, and the anti-tarnish factor comprises a water-soluble amine compound. According to the polyhexamethylene guanidine silver ion composite disinfectant, the concentration of silver ions is reduced while an excellent sterilization effect can be achieved, and the polyhexamethylene guanidine silver ion composite disinfectant has good discoloration resistance, including non-discoloration at high temperature, non-discoloration under sunlight exposure, chlorine resistance and the like.

Description

technical field [0001] The invention relates to the field of silver ion disinfectants, in particular to a polyhexamethyleneguanidine silver ion composite disinfectant. Background technique [0002] At present, the most widely used chemical disinfectants mainly include: alcohol, hydrogen peroxide, potassium permanganate, aldehydes, etc. These disinfectants are highly irritating and highly oxidizing, and can easily cause permanent damage to the skin. At the same time, most of the disinfection products on the market are flammable or flammable, which puts forward higher requirements for the production, transportation and use environment. [0003] Polyhexamethyleneguanidine is an environmentally friendly high molecular polymer and the most widely used broad-spectrum fungicide. It has the characteristics of fast action speed, long antibacterial effect, weak corrosion, stable performance, etc., and is safe to use. However, when used alone, it cannot kill bacterial spores and bacte...

AI Technical Summary

Problems solved by technology

When used alone, it can kill mycobacteria, fungi, viruses and bacterial propagules at higher concentrations, and is a medium-efficiency disinfectant; but its bactericidal ability is limited at low concentrations

When used in high concentrations, not only the cost is high, but also it will cause irritation to human skin and mucous membranes

[0005] Many silver ion compound disinfectants currently on the market have many problems: 1. They are not resistant to chloride ions. When diluted with tap water, the chloride ions in tap water will react with silver ions to produce white precipitates, which will affect the use of disinfectants.

2. It is not resistant to high temperature and sunlight. During the transportation and use of the product, if the product is stored under high temperature for a long time, the silver ion disinfectant will gradually decompose, affecting the appearance and performance of the product

3. After spraying silver ion disinfectant, after drying, the residual Ag+ on the surface of the object will gradually oxidize into silver oxide and turn black, affecting the appearance
