Technical Field

The invention belongs to the field of a sterilizing agent, and particularly relates to an efficient and durable sterilizing agent and a using method thereof.

Background

At present, the common disinfectant comprises 84 disinfectant, peracetic acid, soda water, bleaching powder, potassium permanganate and the like, and research on novel coronavirus shows that the chlorine-containing disinfectant can effectively kill the virus in a short time, so that the chlorine-containing disinfectant is widely applied in spraying. Since the main transmission of the virus is via aerosol (droplet), that is, the virus droplets are mixed in the air to form a nucleus with virus droplets, the human body is easy to cause infection after inhaling, which provides the possibility of transmitting the virus through the air, and the virus aerosol can be suspended in the air. Therefore, the disinfectant can effectively capture and kill the virus by suspending in the air for a long time in a manner similar to aerosol during the killing process. In particular, the disinfectant can be dispersed to be fine enough and the specific gravity and the particle size are small enough, so that the disinfectant can be suspended more easily, and the sterilizing capability of the disinfectant can be improved. At present, the chlorine-containing disinfectants comprise 84 disinfectant, sodium hypochlorite, calcium hypochlorite, chlorine dioxide, dichloroisocyanuric acid and the like, and the disinfectants are difficult to suspend and are mostly used for spraying and wiping due to large specific gravity, so that the dosage of the disinfectants is larger than that of spraying. Improvements are therefore needed.

Disclosure of Invention

In order to solve the problems, the invention provides an efficient and durable disinfectant and a using method thereof. The disinfectant prepared by the invention has the advantages of light weight, difficult sedimentation, easy floating and more efficient and durable disinfection.

In order to achieve the technical effects, the technical scheme of the invention is as follows:

the efficient durable disinfectant consists of chlorine-containing disinfectant 100 weight portions, carrier 0.5-1 weight portion, activator 2.5-10 weight portions and thickener 0.01-0.05 weight portion.

In a further improvement, the chlorine-containing disinfectant is an aqueous solution of chlorine dioxide or dichloroisocyanuric acid with the concentration of 20000 mg/L.

In a further improvement, the support is modified silica.

Further improvement, the modification method of the modified silicon dioxide comprises the steps of adding a silane coupling agent into water, then adding nano silicon dioxide, stirring at a high speed of 1000r/min for more than 30min, and then carrying out suction filtration and drying to obtain the modified silicon dioxide; wherein the mass ratio of the silane coupling agent to the water to the nano silicon dioxide is 0.5: 100: 50.

in a further improvement, the silane coupling agent is KH550 or KH 560.

In a further refinement, the activator is citric acid.

In a further improvement, the thickener is carboxymethyl cellulose.

The application method of the high-efficiency durable disinfectant comprises the following steps:

diluting the disinfectant by 10-200 times with purified water, and atomizing with ultrasonic aerosol generator to obtain diluted disinfectant containing 10-100mg/L effective chlorine.

The invention has the advantages and the principle that:

hydrophilic nano silicon dioxide is added into the chlorine-containing disinfectant, so that chloride ions are adsorbed, the silicon dioxide after hydrophilic modification has technical indexes (the particle size is 9-11 mu m, the specific surface area is 220 +/-20 m2/g, and the bulk density is less than or equal to 100 g/L), the silicon dioxide after hydrophilic modification does not agglomerate in a water phase, is dispersed into independent nano particle dispersoids which can be completely suspended in water under a static state, meanwhile, the nano silicon dioxide plays a role of a carrier for disinfectant molecules and has a slow release effect without chemical reaction with drugs in the disinfectant, and the silicon dioxide with a porous structure has a large specific surface area, has strong adsorbability and can uniformly adsorb the chloride ions, so that the disinfectant is more efficient and durable. Citric acid is used as an activating agent of the disinfectant, and a proper amount of carboxymethyl cellulose is added as a thickening agent of the disinfectant to adsorb effective bactericidal ions on the surface of silicon dioxide.

The prepared medicament disperses the nano particles and liquid drops into 1-10um fine light fog particles through an ultrasonic technology, and the fog particles float in the air, so that the aim of killing in a disinfected space is fulfilled.
