A kind of antibacterial composition and its application

Abstract

The invention relates to an antibacterial composition, comprising an organic antibacterial component containing at least one pyrithione salt, a pyrithione complex or an adduct thereof, an aqueous solution containing one or more metal ions or its The inorganic antibacterial component of the complex aqueous solution or its nanometer metal hydrosol or its nanometer metal oxide hydrosol and its composition, and the mass ratio of the organic antibacterial component to the inorganic antibacterial component is 1:100-50:1, It also includes other auxiliary agents, and its mass percentage in the antibacterial composition described in the patent is 0.001-20%. The antibacterial composition of the present invention can form a nanoparticle film on the surface of base materials such as natural fabrics, non-woven fabrics, clothing, bedding, toiletries, household items, medical care supplies, and filter screens, and realize its antibacterial properties through the nanoparticle film. Antibacterial, anti-mite, deodorizing and self-cleaning functions. The antibacterial composition of the invention is safe to use and can be used in medical treatment and life to protect people's health.

Description

【Technical field】 [0001] The invention relates to the technical field of antibacterial, anti-mite, deodorant and self-cleaning products. More specifically, the present invention relates to a functional composition with antibacterial, anti-mite, deodorant and self-cleaning properties, and also relates to the use of the antibacterial composition as an anti-bacterial, anti-mite, deodorant and self-cleaning finishing agent.

AI Technical Summary

Problems solved by technology

Silver ions are chemically bonded to cotton fabrics, and the antibacterial and washing resistance of the finished fabrics is greatly improved. The antibacterial rate of fabrics treated with unstable nano silver ion antibacterial finishing agents can reach more than 90% after being washed 20 times, which is relatively stable. The nano-silver ion antibacterial finishing agent has an antibacterial rate of over 90% after being washed with water for 10 times, but based on the activity of silver ions, the treated fabric will undergo unpredictable color changes under natural light; Based on its nano effect, it can be attached to the surface of the fiber, and the combination is relatively firm. After the fabrics treated with this kind of finishing agent are washed 20 times with water, the antibacterial rate is over 90%. is greatly limited in scope
