Background
The clinical manifestations of patients with pneumonia infected by the novel coronavirus are: the symptoms of fever, hypodynamia and dry cough are mainly manifested, and symptoms of upper respiratory tract such as nasal obstruction, watery nasal discharge and the like are rare, and the hypoxia and hypoxia state can occur. Approximately half of patients develop dyspnea after one week, and severe patients rapidly progress to acute respiratory distress syndrome, septic shock, refractory metabolic acidosis, and procoagulant dysfunction. It is noted that the severe and critically ill patients may have moderate or low fever during their course, even without significant fever. Some patients have slight onset symptoms, but no fever, and recover after a week. The prognosis is good for most patients, and the disease is critical or even death for a few patients.
The novel routes of coronavirus transmission are mainly direct transmission, aerosol transmission and contact transmission. Direct transmission refers to infection caused by sneezing, coughing, speaking droplets and direct inhalation of exhaled air in close proximity; aerosol transmission refers to the mixing of droplets in the air to form an aerosol which causes infection after inhalation; contact transmission refers to the condition that droplets are deposited on the surface of an article and contact with mucous membranes such as oral cavity, nasal cavity, eyes and the like after contacting with contaminated hands, so that infection is caused.
Currently, the main disinfection methods for the novel coronavirus are: ultraviolet rays, ozone, 75% alcohol, chlorine-containing disinfectants, and the like. These disinfection methods all have a certain degree of influence on the indoor environment or have a certain degree of risk to human health. Therefore, there is a strong need for a disinfecting composition, method and use thereof to solve the problems of the prior art.
In order to solve the technical problems, a new technical scheme is especially provided.

The composition of the present invention comprises 4-tolyl-diiodomethyl sulfone. 4-tolyl-diiodomethyl sulfone has a CAS registry number of 20018-09-1. Other designations for 4-tolyl-diiodomethyl sulfone are as follows: diiodomethyl-p-tolylsulfone, p-tolyl-diiodomethyl sulfone, diiodomethyl-tolyl sulfone. 4-tolyl-diiodomethyl sulfone is an antimicrobial agent that is widely used to control degradation by bacteria. It has been EPA certified registration for use in adhesives, paper coatings, plastics, tanned leather, caulks, metal working fluids, textiles, coatings and wood preservation. The advantage of using 4-tolyl-diiodomethyl sulfone is that it is an extremely effective disinfectant; in several indirect food contact applications, approved by the U.S. FDA; effective over a wide pH range (2-11); has no irritation to skin.
The composition of the present invention comprises polyhexamethylene guanidine. Polyhexamethylene guanidine is an environment-friendly high-molecular polymer disinfectant, and is also named as polyhexamethylene guanidine (hydrochloride). The polyhexamethylene guanidine has the advantages of broad sterilization spectrum, low effective concentration, high action speed, stable property, easy water solubility, long-term bacteriostasis, no side effect, no corrosiveness, no color, no odor, no toxicity, no combustion, no explosion, safe use, moderate price and convenient transportation. It is an environment-friendly multipurpose novel polymer, and has wide application in industry, agriculture, medical use and daily life.
The invention uses a combination of 4-tolyl-diiodomethyl sulfone, polyhexamethylene guanidine, and nanosilica in the disinfecting composition. The aging test report of the silicon dioxide disinfectant is as follows:
first, antibacterial experiment.
As shown in fig. 1 to 3, 100% all-cotton textiles purchased in the market were divided into two. And the dried sample was used as a mold growth test. The above is 28 degrees + -2 degrees. And 100% of all-cotton textile fabric samples are pasted on the inorganic agar culture medium. The same amount is added.
And II, antifungal testing.
As shown in figures 4 to 6, 100% of all-cotton cloth purchased from the market was divided in half, one half of which was sprayed with AF cleaning disinfectant on the surface and the other half was subjected to the mold growth test in the normal manner. The sample is pasted on an inorganic agar culture medium, the temperature is controlled to be about thirty degrees, and the humidity is controlled to be about 85 percent, so that the test is carried out. And (5) carrying out wet process and placing.
Moreover, the above test environment was converted into a practical evaluation standard, and seven days were about three months, and 14 days were about one year.
The composition of the present invention comprises nanosilica and deionized water. The nano silicon dioxide and the deionized water are mixed to form the nano silicon oxide transparent liquid, the pH value range is 6.8-8.3, the nano silicon oxide transparent liquid has excellent cohesiveness, film forming property, activity, large specific surface area, non-toxicity, tasteless and other properties, is widely applied to the industries of electronics, catalysts, refractory materials, coatings, printing ink, textiles, food and the like, and has specific application scenes that: bedding and pillowcase. Blankets, sponge mattresses, shoe cabinets, leather shoes, boots, socks, western-style clothes and underwear. Curtain, wall paper, sofa, air conditioner filter, garbage bin. Washing machines, washing rooms, toilets and the like have a space around the water. Beds and living spaces, bathrooms. Sporting goods, bags, and the like.
In the experiment, as shown in fig. 12 and 13, the test results of AF on virus were that the virus infection rate was reduced by 3.7 x 10 after 15 minutes of use10The above.
As shown in fig. 14 and 15, the detection results of the sterilization test: after 1 minute of use, staphylococcus aureus and escherichia coli both decreased by more than 99.9%.
As shown in fig. 16, 17 and 18, the experimental conclusion of the deodorization test is: the odor generated by ammonia gas, (acetic) acid gas and isovaleric acid is basically eliminated in a short time. The principle of benefiting is that the bad smell of the mould is generated when the spores are divided and propagated, AF disinfection solution is directly sprayed on the mould, the mould stops being propagated and died immediately, and the mould smell disappears.
