Embodiment 1

[0030] The preparation of compound antibacterial agent of the present invention:

[0031] Step 1: Wash the soybeans, add 3 times the weight of pure water, soak them at 40°C for 24 hours, peel them, and then use a crushing device to crush them into a slurry;

[0032] Step 2: filter the above muddy substance with 80 mesh filter cloth to obtain white emulsion;

[0033] Step 3: Add 4 times the volume of pure water to the white emulsion, then add 800mg / L chitosan (average molecular weight 7.3×10 5 Da, deacetylation degree 87%) for flocculation, after filtration and separation, a transparent liquid was obtained;

[0034] Step 4: After diluting the above transparent liquid (soybean extract) 50 times, add 1% glycine, 0.05% ε-polylysine (molecular weight 3000Da), 0.4% benzalkonium chloride respectively Ammonium (wherein the molar ratio of C14 side chain is 50%, the molar ratio of C12 is 40%, and the molar ratio of C16 is 10%) and 0.6% didecyldimethyl ammonium chloride, and the balan...

Abstract

The invention provides a compound antibacterial agent and a preparation method thereof. The compound antibacterial agent comprises the following components in portions by weight: 100 portions of water, 0.5-10 portions of soybean extract, 0.5-2.5 portions of glycin, 0.005-3.0 portions of epsilon-polylysine, 0.1-5.0 portions of benzalkonium chloride and 0.1-6.0 portions of didecyl dimethyl ammoniumchloride. The preparation method comprises the following steps: diluting the soybean extract with water, and adding the glycin, the epsilon-polylysine, the benzalkonium chloride and the didecyl dimethyl ammonium chloride according to the ratio to obtain the compound antibacterial agent. The compound antibacterial agent is novel antibacterial agent having no harm to people and livestock and high sterilizing capability, can be used in various locations to be sterilized and disinfected, and has the advantages of low cost, wide application range, good sterilizing effect and the like.

Description

technical field [0001] The invention relates to a compound antibacterial agent and a preparation method thereof. Background technique [0002] The synergistic use of different antibacterial agents can often give full play to the advantages of these antibacterial agents, so as to achieve the purpose of improving antibacterial ability and reducing the dosage of antibacterial agents. Therefore, the synergistic use of antibacterial agents has always been a focus and direction of people's attention. [0003] Quaternary ammonium salt disinfectant has a history of nearly a hundred years since its discovery, and now there are thousands of varieties. According to the history of quaternary ammonium salt development, it can be divided into 7 generations of products at present, among which the mixed type quaternary ammonium salt antibacterial agent of double long-chain quaternary ammonium salt and alkyl dimethyl benzyl ammonium chloride single-chain quaternary ammonium salt has absorbe...
