Problems solved by technology

[0014] However, although various organic or inorganic antiviral compositions are provided in the above-mentioned prior art, the following problems still exist: the effective component is single, and the simple addition of inorganic materials or organic materials is often used.
[0015] However, this effect cannot be achieved by simply increasing the content of organic active units or met

preparation example 1

[0090] S1: Disperse 12 g of anatase-type nano titanium dioxide (particle size 30-40 nm) in 100 mL of distilled water under stirring conditions to obtain a titanium dioxide suspension; add 0.35 g of cuprous oxide (median particle size 20 nm) to the suspension, Stir and disperse, then add 1.2 g of polyoxyethylene lauryl ether phosphate zinc salt (AEO-Zn) under rapid stirring, and disperse quickly until uniform, to obtain a cuprous oxide-doped titanium dioxide dispersion.

[0091] S2: Add 1.2g of 40-50nm zinc-loaded zirconium phosphate powder dispersed in 10ml methyl ethyl ketone solvent to the above titanium dioxide dispersion under stirring condition; add the above lauryl polyoxyethylene ether phosphate salt surface activity after stirring evenly to 2 wt%, heated to 45° C. and stirred for 15 minutes, and cooled to room temperature to obtain an inorganic metal nanocomposite dispersion.

preparation example 2

[0093] In a four-necked flask equipped with magnetic stirring and a reflux condenser, replace the air atmosphere with nitrogen gas, first add 100ml of chloroform solvent and 0.11mol of triphenylphosphine, and slowly use a dropping funnel at 50°C under stirring conditions. Add 0.1 mol of p-bromostyrene dropwise, after the dropwise addition, heat up to reflux and continue to stir for 6 hours; after the reaction is completed, cool to room temperature, add 30ml of distilled water, extract 3 times with dichloromethane, combine the organic phases and evaporate the solvent under reduced pressure , the obtained solid was recrystallized with ether and then dried in a vacuum oven to obtain a solid monomer of styryl triphenylphosphine quaternary phosphonium salt whose coordination anion is bromide ion, with a yield of 88%.

Abstract

The invention provides an antiviral water-based matrix emulsion composition and an antiviral coating containing the same. The emulsion composition is composed of an inorganic metal nanocomposite dispersion liquid with photocatalytic antiviral activity, a water-based high-molecular polymer emulsion containing a high-content quaternary phosphonium salt unit, and an optional polyvinyl alcohol auxiliary agent. The water-based matrix emulsion or the coating thereof can be used for surface coating treatment of textile articles, plastic products, glass products, leather, wooden products and other objects, so that the virus activity on the surfaces of the objects is reduced or inactivated in a short time, and the effects of inhibiting viruses and blocking propagation are achieved.

Description

technical field [0001] The present invention relates to an antiviral aqueous matrix emulsion composition for coating films, an antiviral paint comprising the aqueous matrix emulsion composition, and a method for forming an antiviral coating film using the paint. Background technique [0002] In recent years, pathogenic viruses caused by various influenza or coronaviruses have brought great negative social impact due to their ease of transmission. Influenza viruses, for example, are ubiquitous pathogens that infect at least tens of millions of people each year. Coronaviruses such as COVID-19 have caused worldwide epidemic infections with their strong infectivity. At the same time, the number of people infected with other viruses such as HIV and hepatitis virus is gradually increasing. In addition to air droplet transmission, influenza viruses and coronaviruses are usually spread by aerosol particles attached to the surface of objects and then contacted by other people. To ...
