Abstract

The invention belongs to the technical field of health disinfection, and discloses a composite bactericide. The composite bactericide comprises, by weight, 15 to 30% of a single chain quaternary ammonium salt, 25 to 40% of a double chain quaternary ammonium salt, 0.1 to 5% of a phenol bactericide, 2 to 10% of a nonionic surfactant, and the balance deionized water. The invention also discloses a preparation method and applications of the composite bactericide. Synergistic interactions of the ingredients are realized, mutual promoting effect is achieved, sterilizing effect is improved obviously,sterilizing speed is accelerated, using concentration is lower, the composite bactericide is nontoxic, no irritation is caused, storage is stable, the composite bactericide is safe and green, and isfriendly to the environment. Operation of the preparation method is convenient, and industrialized production can be realized easily.

Description

technical field [0001] The invention relates to the technical field of sanitation and disinfection, in particular to a composite fungicide and a preparation method thereof. Background technique [0002] Due to the improvement of people's quality of life, various chemical agents and composite materials with bactericidal function are constantly being paid attention to. Quaternary ammonium salt compounds have been widely used because of their efficient bactericidal properties. Quaternary ammonium salt compounds include two types of single-chain quaternary ammonium salts and double-chain quaternary ammonium salts. The bactericidal principle of ammonium) is to adsorb bacteria and destroy the outer membrane of bacteria, but it can only kill some bacterial propagules and lipophilic viruses, but cannot kill bacterial spores, and has a low killing rate for Pseudomonas aeruginosa. Double-chain quaternary ammonium salts such as didecyldimethylammonium chloride can kill a variety of mi...
