Disinfectant and preparation method thereof

Abstract

The invention discloses a disinfectant and its preparation method. The disinfectant comprises a compound glutaraldehyde solution and a foaming agent. Volume ratio of the compound glutaraldehyde solution to the foaming agent is 5:1. The compound glutaraldehyde solution comprises glutaraldehyde, benzalkonium chloride, double-chain quaternary ammonium salt A, double-chain quaternary ammonium salt B, a nonionic surfactant A and a nonionic surfactant B. The double-chain quaternary ammonium salt A and the double-chain quaternary ammonium salt B are different substances. The nonionic surfactant A and the nonionic surfactant B are different substances. By cooperatively using glutaraldehyde, two kinds of double-chain quaternary ammonium salts and two kinds of nonionic surfactants, the synergistic effect is achieved, effects are enhanced, and sterilization is comprehensive.

Description

technical field [0001] The invention relates to the field of veterinary disinfectant and its preparation method, in particular to a disinfectant and its preparation method. Background technique [0002] With the continuous increase of scale farming, the concept of "disinfection" has been gradually accepted by the majority of farmers. In animal husbandry production, the choice of high-efficiency and low-toxicity disinfectants has practical and far-reaching significance. In controlling the breeding environment and preventing animal diseases, disinfection is the most effective measure to prevent and exterminate infectious diseases; and choosing an ideal disinfectant is the key to prevent and control infectious diseases. In the past more than one hundred years, a single disinfectant was mainly used, and compound disinfectants were rarely used. From the beginning of the 21st century to the present, the compounding of chemical disinfectants has become an important research direc...

AI Technical Summary

Problems solved by technology

However, using glutaraldehyde alone for disinfection has weak bactericidal ability and poor stability under acid-base conditions.

Quaternary ammonium salt cationic surfactants have the function of disinfection and sterilization, and are widely used in disinfectants. Among various surfactants, cationic quaternary ammonium salt bactericidal disinfectants have the best antibacterial and bactericidal properties, including single There are two types of chain quaternary ammonium salts and double-chain quaternary ammonium salts. Single-chain quaternary ammonium salts can only kill certain bacterial propagules and lipoviruses, while double-chain quaternary ammonium salts can kill a variety of microorganisms, including bacterial propagules, Fungi and viruses, but the combined use of single and double chain quaternary ammonium salts still cannot kill mycoplasma and spores

Quaternary ammonium salts are often added to glutaraldehyde-based compound disinfectants, but when glutaraldehyde is used in combination with single-chain quaternary ammonium salt benzalkonium chloride, benzalkonium chloride itself has a certain crystallization at low temperature, so the prepared The properties and stability of the disinfectant are not good and need to be further improved; the combined use of glutaraldehyde and double-chain quaternary ammonium salt is susceptible to organic matter and becomes invalid

Therefore, the sterilization and disinfection effects are all unsatisfactory
