Quaternary ammonium salt disinfectant composition used for electronic product and method thereof

Abstract

The invention relates to a quaternary ammonium salt disinfectant composition and a method thereof. The quaternary ammonium salt disinfectant composition is characterized in that a host quaternary ammonium salt disinfectant composition is prepared from the following components in percentage by weight: 0.005% to 2.00% of single-chain quaternary ammonium salt, 0.005% to 3.00% of double-chain quaternary ammonium salt, 0.0001% to 0.001% of Cu2<+>-containing synergist, and the balance of solvent. The method comprises the step of fully and uniformly stirring the components at normal temperature to obtain the quaternary ammonium salt disinfectant composition. The quaternary ammonium salt disinfectant composition has good broad-spectrum germicidal efficacy, can effectively extinguish various bacteria such as escherichia coli, bacillus subtilis and staphylococcus aureus, and also can effectively extinguish various moulds such as blue mould, aspergillus niger and aspergillus flavus, as well as effectively extinguish various saccharomycetes such as tritirachium album. The quaternary ammonium salt disinfectant composition shows fast speed in sterilization, can extinguish more than 99.99% of various microorganisms within 1 to 2 minutes, is low in sterilization concentration, simple and convenient to prepare, low in cost and environmentally-friendly.

Description

[technical field] [0001] The present invention relates to quaternary ammonium salt disinfectant compositions and methods. [Background technique] [0002] With the rapid development of electronic technology, many electronic products such as televisions, telephones, computers, mobile phones, keyboards, and mice have entered thousands of households. It is necessary to deal with these electronic products all the time, even when eating and sleeping without them. While people fully enjoy the convenience and fun that these electronic products bring to people, they may also pose threats to people's health. One of them is that these electronic products carry various viruses and microorganisms. According to a study by the University of Arizona in the United States, compared with the toilet seat, there are about 3900 microorganisms per square centimeter on the mobile phone, and the number of microorganisms per square centimeter on the keyboard and mouse is 510 and 260 respectively.

AI Technical Summary

Problems solved by technology

However, the commonly used disinfection products containing quaternary ammonium salts on the market often contain a single quaternary ammonium salt, or a quaternary ammonium salt with a certain chain length, such as a disinfectant containing only a single-chain quaternary ammonium salt. It can only kill certain bacterial propagules and lipophilic viruses, and is a low-efficiency disinfectant

Although some disinfectants contain double-chain quaternary ammonium salts, which can kill a variety of microorganisms, including bacterial propagules, some fungi and viruses, there are still problems with different bactericidal effects due to the different carbon chain lengths of quaternary ammonium salts.
