Composite photocatalytic quaternary ammonium salt disinfectant capable of continuously killing microorganisms and viruses

Abstract

The invention discloses a compound photocatalytic quaternary ammonium salt disinfectant capable of continuously killing microorganisms and viruses. The compound photocatalytic quaternary ammonium salt disinfectant is prepared from the following raw materials: a compound quaternary ammonium salt glutaraldehyde solution, didecyl dimethyl ammonium bromide, dodecyl dimethyl benzyl ammonium chloride, a guanidine disinfectant, a synergist, a pH regulator, a cosolvent and deionized water. Through cooperation of dodecyl dimethyl benzyl ammonium chloride and didecyl dimethyl ammonium bromide, the efficient disinfectant has the characteristics of an efficient disinfectant, can achieve long-time and efficient inhibition and killing effects on microorganisms and viruses, and utilizes unsaturated aldehyde groups existing in the compound quaternary ammonium salt glutaraldehyde solution to effectively inhibit and kill the microorganisms and the viruses. The antibacterial agent can act on sulfydryl, hydroxyl, carboxyl and amino of cell wall lipoprotein or other components, hinder absorption of nutrient substances by microorganisms and discharge of waste, inhibit activity of dehydrogenase and periplasmin and inhibit synthesis of RNA, DNA and protein, so that the effect of rapid sterilization is achieved.

Description

technical field [0001] The invention relates to the technical field of disinfectant preparation, in particular to a composite photocatalytic quaternary ammonium salt disinfectant that can continue to kill microorganisms and viruses. Background technique [0002] Quaternary ammonium salt disinfectant is a kind of cationic surfactant, which was mass-produced and applied in China in the 1960s, such as Jieerfen (Benzalkonium Dialkyldimethylphenoxyethylammonium bromide) and some compound quaternary ammonium salt disinfectants, etc., can kill most bacterial propagules, mold viruses, mild and non-irritating ingredients, suitable for hospitals, schools, home In terms of disinfection, quaternary ammonium salt disinfectants can be divided into three categories according to their components, including disinfectants with a single quaternary ammonium salt component, disinfectants with multiple quaternary ammonium salts, and disinfectants with 65% to 75% ethanol or isopropyl. Alcohol com...

Problems solved by technology

[0003] Although quaternary ammonium salt disinfectants have the advantages of low bactericidal concentration, colorless, low odor, no corrosive bleaching effect, relatively stable performance, light and heat resistance, easy storage, and low toxicity, etc., but quaternary ammonium salt disinfectants belong to Low-efficiency disinfectants cannot kill microorganisms such as fungi, Mycobacterium tuberculosis, hydrophilic viruses, and bacterial spores. Restricted, and long-term use alone will produce drug resistance, and the synergistic effect of compound quaternary ammonium salts will have a better broad-spectrum bactericidal effect and many other advantages, such as: prolonging the sterilization cycle, expanding the antibacterial spectrum and antibacterial range , reduce the use concentration, prevent bacteria from developing drug resistance, etc., through the compounding of traditional quaternary ammonium salts and new quaternary ammonium salts and other types of surfactants or fungicides, it can also achieve synergistic effect and improve the bactericidal effect. For this reason, A composite photocatalytic quaternary ammonium salt disinfectant that can continue to kill microorganisms and viruses is now proposed
