Embodiment 1

[0052] 1. Preparation of nitrogen-doped nano-titanium dioxide bactericidal disinfectant

[0053] The amount of substance ratio m (n-tetrabutyl titanate): m (absolute ethanol): n (deionized water): n (acetic acid): n (guanidine acetate) = 1: 20: 1: 0.1: 0.10; at room temperature Under certain conditions, the mixed solution was obtained according to the volume ratio (V butyl titanate: V absolute ethanol = 1:4), and the magnetic stirrer was stirred at 400r / min, and the acetic acid solution and deionized water were slowly added dropwise into the mixed system. The pH value of the solution is 2.0; then slowly drop the guanidine acetate solution into the butyl titanate solvent solution according to the volume ratio (V guanidine acetate: V butyl titanate = 1:2), and stir thoroughly for 1 hour to obtain a dispersion; the above dispersion Put it into a drying device, dry it at 80°C for 10 hours, and then grind it to obtain a powder. Finally, the powder is placed in a muffle furnace and...

Abstract

The invention relates to a preparation method of a sterilization disinfectant for killing coronaviruses. The preparation method comprises the following steps: mixing a surface-modified nano nitrogen-doped nano titanium dioxide solution and a surface-modified nano plant extract solution, magnetically stirring the mixture, and carrying out ultrasonic dispersion to obtain the composite sterilizationdisinfectant. According to the composite sterilization disinfectant, the sterilization and disinfection capacity of nano titanium dioxide and plant extracts can be remarkably improved, particularly, the coronavirus killing capacity is improved, and the product stability is high.

Description

technical field [0001] The invention relates to a preparation method of a composite bactericide, in particular to a preparation method of a bactericidal disinfectant for killing coronaviruses, and belongs to the field of spectral bactericidal disinfectants. Background technique [0002] Viruses of the genus Coronavirus are RNA viruses with an envelope and a linear single-stranded positive strand genome. They are a large class of viruses that exist widely in nature; the diameter of coronaviruses is about 60-140nm, and the 5′ end of the genome has methylation The cap-like structure has a poly(A) tail at the 3′ end, and the genome is about 27-32kb in length. It is the virus with the largest genome among known RNA viruses; coronaviruses can cause upper respiratory tract infections in humans, and some severe cases can cause acute Respiratory distress syndrome or septic shock, or even death; at present, there is a lack of effective antiviral drugs against pathogens, and isolation ...
