Abstract

The invention provides a disinfectant containing amines and quaternary ammonium salt and a preparation method thereof. The disinfectant containing amine and quaternary ammonium salt comprises the following components in percentage by mass: 5-30% of quaternary ammonium salt, 1-10% of an amine compound, 1.5-10% of a corrosion inhibitor, 0.51-2% of a surfactant, 0.5-6% of a chelating agent and the balance of pure water. The preparation method comprises the following steps of: weighing the quaternary ammonium salt, the amine compound, the corrosion inhibitor, the surfactant, the chelating agent and the pure water according to the formula ratio, dissolving the quaternary ammonium salt and the amine compound in the pure water, performing stirring, adding the corrosion inhibitor and the surfactant, performing uniform dissolving, adding the chelating agent, and performing stirring. The prepared disinfectant containing amines and quaternary ammonium salt is good in disinfection and sterilization effect, short in sterilization time, stable in performance and low in corrosion to equipment.

Description

technical field

[0001] The invention relates to the field of disinfectants, in particular to a disinfectant solution containing amines and quaternary ammonium salts and a preparation method thereof. Background technique

[0002] The quaternary ammonium salt disinfectant has the advantages of stable performance, low toxicity and irritation, rapid bactericidal effect, low concentration, no bad smell, etc., and the biodegradability of the quaternary ammonium salt disinfectant is good. It is an environmentally friendly disinfectant. Attention of disinfection scholars. The development of quaternary ammonium salt disinfectant has gone through many stages, and the bactericidal activity is constantly improving, but it still takes a long time to achieve the ideal disinfection effect. In addition, quaternary ammonium salt disinfectants are more sensitive to metal ions such as calcium and magnesium, and calcium and magnesium ions are easy to form quaternary ammonium salt compounds wit...
