Problems solved by technology

Currently commercially available quaternary ammonium salt disinfectant products are generally a single-chain quaternary ammonium salt, or a double-chain quaternary ammonium salt, or a compound of a single-chain quaternary ammonium salt and a double-chain quaternary ammonium salt. Among them, the single-chain quaternary ammonium salt can be used to disinfect bacteria and fungi, and the double-chain quaternary ammonium salt can disinfect bacteria, fungi and viruses at the same time. If the value is >3, the virus inactivation rate is >99.9%, and the inactivation logarithm value >4 specified in the disinfectant standard is not reached, and the virus inactivation rate is >99.99%, and there is a defect that the virus killing effect is not good

Abstract

The invention discloses a composite quaternary ammonium salt disinfectant, which is prepared from the following components in terms of 1000mL of volume of the composite quaternary ammonium salt disinfectant: 5g to 30g of didecyldimethylammonium chloride, 5g to 30g of didodecyl dimethyl ammonium chloride, 10g to 50g of benzalkonium chloride, 5g to 30g of disodium ethylenediamine tetraacetate, 5g to30g of tetrasodium ethylenediamine tetraacetate, 0.1 g to 10g of polyvinylamine, 30mL-120mL of ethanol and the balance being water. The benzalkonium chloride is a compound of dodecyl dimethyl benzylammonium chloride, tetradecyl dimethyl benzyl ammonium chloride and hexadecyl dimethyl benzyl ammonium chloride in a mass ratio of (2-6): (2.5-10): 1. The composite quaternary ammonium salt disinfectant disclosed by the invention is short in virus, bacterium and fungus killing time, takes effect quickly, has broad universality, does not cause water body pollution and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of disinfectants, in particular to a compound quaternary ammonium salt disinfectant. Background technique [0002] Alcohol and / or sodium hypochlorite are the main components of disinfectants currently used in places such as public places and homes to disinfect the air and the surfaces of various objects, and their main purpose is to disinfect pathogenic microorganisms such as viruses. However, alcohol is flammable and explosive, and it is easy to cause accidents such as fires. It is not suitable for large-scale disinfection. Chlorine-containing disinfectants such as sodium hypochlorite are strongly irritating and corrosive. If diluted or used improperly, it is easy to produce toxic and harmful substances such as chlorine. cause personal injury. [0003] Quaternary ammonium salt disinfectant is a disinfectant with quaternary ammonium salt as the main component. Due to its advantages of low irritation and non...
