Problems solved by technology

In order to effectively inhibit the growth of bacteria, a lot of improvements have been made to the production process of non-woven fabrics, but the research on anti-virus non-woven fabrics still has not appeared.
In particular, the non-woven fabrics currently used in the market basically do not have anti-virus capabilities, and the non-woven fabrics after melt blown winding are directly put into the production of products in the downstream market without effective anti-virus treatment
At present, the most widely used method for antibacterial and antiviral treatment of non-woven fabrics is to spray various pharmaceutical preparations on non-woven fabric materials, but there is no antiviral agent for spraying long-term and highly effective antiviral agents

preparation example Construction

[0037] On the other hand, the present invention also provides a kind of preparation method of composite nano-silver antiviral agent, comprises the following steps:

[0038] Step S1: Weighing the raw materials for preparing the composite nano-silver antiviral agent according to the mass ratio; dividing the water into the first part of water and the second part of water;

[0039] Step S2: Mix the first part of water with the ester-based quaternary ammonium salt cationic surfactant and dodecyltrimethylammonium chloride, and fully stir for 10-30min (the stirring time is too short, the mixing is uneven, and the stirring time is too long , the effect is improved not obviously and wastes time), the first mother liquor is formed;

[0040] Step S3: Mix the second part of water with nano-silver sol and polyethylene glycol, and fully stir for 10-30 minutes (the stirring time is too short, the mixing is uneven, the stirring time is too long, the effect is not obvious and time-consuming), an...

Embodiment 1

[0058] This embodiment provides a composite nano silver antiviral agent, the mass parts of raw materials are: ester group quaternary ammonium salt cationic surfactant: 0.7 part, dodecyl trimethyl ammonium chloride: 0.06 part, nano silver Sol: 5 parts, polyethylene glycol: 0.3 parts, water: 100 parts.

Embodiment 2

[0060] In the preparation method of the composite nano-silver antiviral agent of the present embodiment, raw material is: the ester group quaternary ammonium salt cationic surfactant of 0.5 mass part, the polyethylene glycol (average molecular weight is 200) of 0.6 mass part, 0.05 mass part Dodecyltrimethylammonium chloride (active matter content is 60%), 100 parts by mass of pure water, 1 part by mass of nano-silver sol, wherein the average particle size of nano-silver particles is 10nm.

[0061] The composite nano-silver antiviral agent obtained under the above ratio is sprayed on the non-woven fabric, and the drying temperature is 100°C.

Abstract

The invention discloses a composite nano-silver antiviral agent as well as a preparation method and application thereof, and belongs to the technical field of health protection. The problems that in the prior art that a nano-silver antiviral agent is low in stability and timeliness; and existing cloth is poor in antiviral property are solved. The composite nano-silver antiviral agent is prepared from the following raw materials: an ester-based quaternary ammonium salt cationic surfactant, dodecyl trimethyl ammonium chloride, nano-silver sol, polyethylene glycol and water. The preparation method of the composite nano-silver antiviral agent comprises the following steps: weighing the raw materials for preparing the composite nano-silver antiviral agent according to the mass ratio; equally dividing water into two parts; preparing a first mother solution; preparing a second mother solution; and mixing and stirring the first mother liquor and the second mother liquor to obtain the compositenano-silver antiviral agent. The composite nano-silver antiviral agent has long-acting and stable bactericidal and antiviral effects, can improve the antiviral property of non-woven fabrics when applied to the non-woven fabrics, and is harmless to human bodies, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of health protection, and in particular relates to a composite nano-silver antiviral agent and its preparation method and application. Background technique [0002] Nano-silver antiviral agent is composed of nano-scale silver ions. It is a non-antibiotic antiviral agent with multiple properties such as broad-spectrum, no drug resistance, and not affected by pH value. Nano-silver antiviral agents are considered to be the most effective in inorganic antiviral agents. It has been proven that the nano-silver antiviral agent not only has the functions of sterilizing, anti-virus, degrading bacteria and organic matter under visible light and ultraviolet light, but also has strong antibacterial, bactericidal and anti-viral effects under no light source. The nano-silver antiviral agents on the existing market have relatively low stability and timeliness when used, and there is an urgent need to improve the stability...
