Problems solved by technology

[0003] Although traditional small molecule antibacterial agents have a wide range of applications, they have disadvantages such as easy volatility, poor stability, and difficult processing.
At present, the research on the performance of quaternary ammonium salts to kill harmful microorganisms mainly focuses on the improvement of their antibacterial and fungal ability, and there are few reports on the antiviral performance of quaternary ammonium salt molecules. However, in the natural environment today The complexity and diversity of harmful microorganisms, as well as the emergence of various drug-resistant bacteria and mutant viruses, urgently require the development of high-efficiency antibacterial disinfectants that can kill both bacteria and viruses

preparation example Construction

[0035] The preparation steps of described composite high-efficiency bactericidal disinfectant are as follows:

[0036] The first step: add water to the batching bucket;

[0037] Step 2: Add the single-chain quaternary ammonium salt directly into the batching tank and stir for 5-15 minutes at a speed of 30-100rpm to completely dissolve it;

[0038] Step 3: Add the double-chain quaternary ammonium salt into the batching tank and stir for 5-15min at a speed of 30-100rpm to dissolve completely;

[0039] Step 4: Add the biguanide compound into the batching tank and stir for 5-15min at a speed of 30-100rpm to dissolve completely;

[0040] Step 5: Add the aloe vera extract into the batching bucket and stir for 5-15 minutes at a speed of 30-100 rpm to completely dissolve it, and let it stand to obtain a solution of the bactericidal disinfectant.

Abstract

The invention belongs to the technical field of medical bacteriostatic agents, and particularly relates to a composite efficient sterilization disinfectant. The composite efficient sterilization disinfectant is prepared from the following components in percentage by weight: 0.2-1.5% of a biguanide compound, 0.05-0.5% of single-chain quaternary ammonium salt, 0.1-0.5% of double-chain quaternary ammonium salt, 0.01-1% of aloe extract and the balance of water. The composite efficient sterilization disinfectant prepared by the invention does not produce precipitates after being placed for a long time, has the characteristics of quick effect and long sterilization duration, and has a lasting sterilization effect for several hours after being sprayed to the skin surface and mucous membrane of ahuman body and the surface of an object. In addition, various bacteria and viruses can be effectively killed, and the sterilization rate reaches 99.99%.

Description

technical field [0001] The invention belongs to the technical field of medical disinfectants, more specifically, the invention relates to a compound high-efficiency bactericidal disinfectant. Background technique [0002] With economic development and social progress, the living environment of human beings has become increasingly harsh, and various new types of pathogenic microorganisms continue to emerge, which seriously threaten human health. In recent years, large-scale outbreaks of epidemics, such as "new coronary pneumonia", are all caused by pathogenic bacteria or viruses, causing worldwide panic. Therefore, in response to the emergence of drug-resistant pathogenic bacteria and mutant new viruses, it has become an urgent task for scientists to develop new broad-spectrum and high-efficiency antibacterial and disinfectant agents. [0003] Although traditional small molecule antibacterial agents have a wide range of applications, they have disadvantages such as easy vola...
