Problems solved by technology

At present, the disinfectant that can be used at low temperature is a chlorine-containing disinfectant containing organic chlorine compounds. When this type of chlorine-containing disinfectant is used, there are the following problems: First, the disinfection effect at low temperature is not satisfactory ; Second, the organic chlorine compounds in chlorine-containing disinfectants contact with water, which will form carcinogens, namely chloroform, which is harmful to human health; third, this type of chlorine-containing disinfectants are corrosive to metals and plastics; Fourth, some products of this type of chlorine-containing disinfectant need to be mixed and used on site, which is troublesome

Abstract

The invention relates to an anti-freezing disinfectant and a preparation method thereof, and belongs to the technical field of disinfection. The final product of the disinfectant is composed of a disinfection component, a freezing point reducing agent, a solvent, a freezing retardant, a surfactant, a synergist, a corrosion inhibitor, water and a pH value regulator. The final product of the disinfectant comprises the following components in percentage by mass: 3 to 10 percent of disinfection component, 20 to 50 percent of freezing point reducing agent, 3 to 8 percent of solvent, 1 to 10 percent of freezing retardant, 2 to 5 percent of surfactant, 0.5 to 2 percent of synergist, 0.2 to 1 percent of corrosion inhibitor and the balance of water, wherein the sum of the mass of the other components in the final product of the disinfectant is 100 percent; and the pH value of the disinfectant is regulated to 7.0-8.5 by using a pH value regulator. The disinfectant has a good anti-freezing effect, a good sterilizing effect, small corrosion to metals and no corrosion to plastics.

Description

technical field [0001] The invention relates to an antifreeze disinfectant and a preparation method thereof, belonging to the technical field of disinfection. Background technique [0002] At present, the commonly used disinfectants for disinfection of articles are: chlorine-containing disinfectants, peroxide disinfectants, and quaternary ammonium salt disinfectants; these disinfectants have poor sterilization effects at low temperatures, and as the temperature decreases, their The bactericidal effect showed an exponential decrease. It can be seen that the sterilizing effect of the disinfectant has a great relationship with the temperature. Effective disinfectants are used at room temperature. When used at low temperatures, their disinfection effect will be greatly reduced or even ineffective. Therefore, in order to achieve effective disinfection, the only solution is to increase the concentration of disinfectants, but this will cause disinfection. The corrosivity of the di...
