Abstract

The invention relates to a novel environmentally-friendly corrosion-resistance peracetic acid disinfectant, and belongs to the technical field of disinfection product preparation. 100 ml of the novel environmentally-friendly corrosion-resistance peracetic acid disinfectant comprises: 0.1 to 0.5 gram of peracetic acid solution, 0.05 to 0.1 gram of stabilizer sodium ethylenediamine tetracetate, 0.1 to 0.2 gram of surfactant sodium citrate, 0.1 to 0.2 gram of quaternary ammonium salt, 0.005 to 0.02 gram of sodium molybdate, and the balance of water. The disinfectant has broad-spectrum sterilization performance, so that the stability of conventional peracetic acid is obviously improved; additives of the disinfectant obviously inhibit the corrosion of the peracetic acid on metal materials, can be suitable for quick and effective sterilization and disinfection in schools, hospitals, factories, mines and other public places, and also can be used for environment disinfection and sterilization of SARS (Severe Acute Respiratory Syndromes), A(H1N1) and other communicable diseases. The disinfectant has no pollution after use, and is safe and convenient to use.

Description

Technical field: [0001] The invention relates to a novel environment-friendly and corrosion-resistant peracetic acid disinfectant, which belongs to the technical field of disinfection product preparation. Background technique: [0002] Bacteria and viruses in public places are often the cause of many infectious diseases. Doing a good job of disinfection in public places can better inhibit the spread and spread of diseases among the crowd. Chlorine and chlorine-containing disinfectants have very strong mutagenic effects. With the development of society, people's awareness of environmental protection and safety is also increasing. Ozone, hydrogen peroxide and peracetic acid are considered to be good alternatives to chlorine and chlorine-containing disinfectants. choose. Among them, peracetic acid has high-efficiency, rapid and broad-spectrum sterilization and disinfection performance. In addition, it is easy to volatilize and decompose. Its decomposition products are non-toxi...
