Embodiment 1

[0023] Embodiment 1, the killing test of compound type disinfectant to virus

[0024]Adopt sodium percarbonate as oxidant, according to sodium percarbonate (oxidation main agent) 2% (mass volume percentage of solid component mass and water volume, g / 100mL, the same below), TAED (activator) 1%, acetylsalicylic acid Acid (activator) 1%, citric acid (buffer) 0.2%, cetyltrimethylammonium bromide (surfactant) 0.01% ratio prepares disinfectant, tests to influenza virus H 3 N 2 and the disinfection effect of poliovirus PV-1. Influenza virus H 3 N 2 and poliovirus PV-1 (Zhang Wenfu, Jiang Li, Yuan Qingxia, etc. Comparative study on the resistance of influenza virus to disinfection treatment. Chinese Journal of Disinfection [J], 2005, 22(2): 121-124) The public can download from China Obtained by the Chemical Defense Command Engineering College of the People's Liberation Army.

[0025] The test method is as follows: mix the disinfectant with 10 4 Virus suspensions of several orde...

Embodiment 2

[0036] Embodiment 2, compound type disinfectant is to the killing test of bacterium

[0037] Using sodium percarbonate as oxidant, according to sodium percarbonate (oxidation main agent) 2%, TAED (activator) 1%, acetylsalicylic acid (activator) 1%, citric acid (buffer) 0.2%, hexadecane Trimethylammonium bromide (surfactant) 0.01% ratio to prepare disinfectant solution, test the disinfection effect on Staphylococcus aureus (ATCC 6538) and Escherichia coli (8099).

[0038] The test method is as follows: suck 5mL of disinfectant solution into a sterile small plate, put it in a water bath at 20°C for 5 minutes, take a bacterial slice with sterile tweezers, immerse it in the disinfectant solution, and take out the bacterial slice immediately after the specified time. In a test tube containing 5mL of 10% sodium thiosulfate solution (neutralizing agent). After rapid shaking and mixing, 1mL of the sample solution was evenly added dropwise on the membrane of the filter, in duplicate, ...

Embodiment 3

[0044] Embodiment 3, compound type disinfectant is to the killing test of spore

[0045] Using sodium percarbonate as oxidant, according to sodium percarbonate (oxidation main agent) 2%, TAED (activator) 1%, acetylsalicylic acid (activator) 1%, citric acid (buffer) 0.2%, hexadecane 0.01% of trimethylammonium bromide (surfactant) was used to prepare disinfectant solution, and the disinfection effect on Bacillus subtilis var. niger spores (ATCC 9372) and Bacillus anthracis spores (170047).

[0046] Test process is the same as embodiment 2, under test temperature 20 ± 1 ℃ of conditions, prove through 3 repeated tests, the disinfectant of present embodiment acts on Bacillus subtilis varietal spore (ATCC 9372) and Bacillus anthracis spore (170047) 30min, The requirement of complete kill can be achieved. See Table 4 for detailed results.

Abstract

The invention discloses a compound high-efficiency biochemical disinfectant with low corrosivity, which comprises the following materials in percentage by weight: 10-80% of main oxidant A and 20-90% of synergistic assistant B, wherein the main oxidant A is a solid peroxide; the synergistic assistant B comprises an activator containing an amide group or ester group; and the main oxidant A and the synergistic assistant B in the disinfectant adopt binary package. Before use, the main oxidant and the synergistic assistant are prepared in proportion into a water solution with the mass concentration of 0.1-10% for disinfection. The disinfectant can efficiently disinfect pathogens of various viruses, bacteria, spores and the like, has good disinfecting effects on toxic and harmful materials of organic phosphorus, sulfur and the like, chemical reagents and the like, and simultaneously has good storage stability, low corrosivity on the surface of disinfection equipment, personnel security and no pollution to the environment.

Description

technical field [0001] The invention belongs to the field of disinfectants, in particular to a low-corrosion and high-efficiency solid binary peroxyacid disinfectant. Background technique [0002] With the development of human material civilization and spiritual civilization, public health safety issues have aroused people's great concern, especially the occurrence of infectious diseases such as SARS, bird flu and influenza A, and a kind of broad-spectrum and efficient disinfectant is urgently sought. At the same time, due to the complexity and uncertainty of the public environment, as well as the increase in drug resistance and variability of viruses, bacteria, and spores, there are higher requirements for the environmental adaptability, environmental compatibility, and high-efficiency broad-spectrum of disinfectants. Require. Therefore, in addition to meeting the broad-spectrum disinfection efficacy in different environments, disinfectants must also be compatible with the...
