Abstract

The invention provides a compound antibacterial agent and a preparation method thereof. The compound antibacterial agent contains the following components in parts by weight: 111 parts of water, 0.5-11 parts of soybean extractive solution, 0.5-2.5 parts of glycine, 0.005-3.0 parts of epsilon-poly-lysine, 0.1-5.0 parts of benzalkonium chloride, 0.01-0.1 part of ergosterol, 0.1-1 part of docosanoic acid, and 0.1-6.0 parts of didecyldimethylammonium chloride. The preparation method of the compound antibacterial agent comprises the steps of diluting soybean extractive solution with water, and proportionally adding glycine, epsilon-poly-lysine, benzalkonium chloride and didecyldimethylammonium chloride. The compound antibacterial agent provided by the invention is not harmful to human and livestock, has high sterilizing capacity, can be used at various sterilizing and disinfecting sites, and has the advantages of low cost, wide application range and good sterilizing effect.

Description

technical field [0001] The invention relates to a compound antibacterial agent and a preparation method thereof. Background technique [0002] Antibacterial agents are chemical substances that can keep the growth or reproduction of certain microorganisms (bacteria, fungi, yeast, algae, viruses, etc.) below the necessary level within a certain period of time. Antibacterial agents are a new class of additives with antibacterial and bactericidal properties. Antimicrobial agents are generally divided into two categories: inorganic and organic. The former uses silver, zinc, copper, etc. as main raw materials, and uses inorganic fillers as carriers to make inorganic antibacterial agents, which have good high temperature resistance. The latter uses esters, alcohols, and phenols as the main raw materials, and has low temperature resistance, generally below 200°C, and some are 250°C, with short sterilization time and occasional precipitation. Inorganic antibacterial agents are mad...
