Embodiment 1

[0031] At normal temperature and pressure, under the condition of 500r / min magnetic stirring, add 0.2g of DICS to 95.85ml of water, after completely dissolving to obtain the initial disinfectant, add 0.3g of sodium carbonate and 0.05g of sodium tetraborate, and stir until completely dissolved , now the pH is 10, then, add 0.4g Triton X-100, 1.0g AES, 0.5g AOS, 1.5g polymerized propylene glycol-400 and 0.2g lauryl alcohol successively, stir until mixing evenly, obtain the A compound disinfectant, wherein the mass percentage of each component is DICS: 0.2%, sodium carbonate: 0.3%, sodium tetraborate: 0.05%, Triton X-100: 0.4%, AES: 1.0%, AOS: 0.5%, Polymerized Propylene Glycol-400: 1.5%, Lauryl Alcohol: 0.2%.

[0032] Carry out dynamic disinfection test to HD with described composite disinfectant:

[0033] Fix the 50mL three-necked bottle on the electric stirrer, use a super constant temperature water bath to control the reaction temperature to 25°C, adjust the stirring speed o...

Embodiment 2

[0036] At normal temperature and pressure, under the condition of 500r / min magnetic stirring, add 3g of DICS to 90.3ml of water, after completely dissolving to obtain the initial disinfectant, add 1.2g of sodium carbonate and 0.2g of sodium tetraborate, stir until completely dissolved, Now the pH is 10, then, add 0.4g Triton X-100, 1.0gAES, 1.5gAOS, 2.0g polymerized propylene glycol-400 and 0.4g lauryl alcohol successively, stir until mixed evenly, obtain a kind of composite Disinfectant, wherein the mass percentage of each component is DICS: 3%, sodium carbonate: 1.2%, sodium tetraborate: 0.2%, Triton X-100: 0.4%, AES: 1.0%, AOS: 1.5%, polymerized propylene glycol- 400: 2.0%, lauryl alcohol: 0.4%.

[0037] Static disinfection test was carried out on HD with the composite disinfectant, that is, dynamic measures such as stirring were not used in the disinfection process.

[0038] Add 10 μL HD into a small test tube with a micro-syringe, and weigh the quality of HD. Slowly add...

Embodiment 3

[0042] Corrosion comparison of compound disinfectant, DICS disinfectant and three-in-two disinfectant to metal:

[0043] First, prepare various disinfectants separately:

[0044] Composite disinfectant: the composite disinfectant prepared in Example 2;

[0045] DICS disinfectant: an aqueous solution with a mass fraction of DICS of 3%;

[0046] Three-in-two disinfectant solution: it is the supernatant liquid of three-in-two saturated solution.

[0047] Then, carry out the corrosion test according to the following steps:

[0048]① Soak stainless steel, carbon steel, copper and aluminum metal sheets in surface-active detergent for 10 minutes, fully degrease and wash them; use 120-grit water sandpaper to grind off both sides and surrounding areas of the metal sheets Then rinse the oxide layer with tap water; degrease again with anhydrous acetone; dry it in a 50°C incubator for 1 hour, and weigh it as a sample after the temperature drops to room temperature; weigh each piece of ...

Abstract

The invention discloses a compound disinfectant, and belongs to the technical field of chemical defense. The compound disinfectant comprises the following components, calculated by total weight of the disinfectant being 100%: 0.2-3% of sodium dichloroisocyanurate, 0.3-1.2% of sodium carbonate, 0.05-0.2% of sodium tetraborate, 0.4% of octyl phenoxy poly ethoxy, 0.5-1.5% of sodium lauryl ether sulfate, 0.5-1.5% of alpha-olefin sulfonate, 1.0-2.0% of poly propylene glycol-400, 0.2-0.4% of dodecanol and the balance of water. The compound disinfectant is capable of promoting dissolution of highly toxic chemicals, with little corrosion and environment-friendly, can effectively meet the general requirements of chemical defense security, and can be used for disinfection of smooth surfaces, such as vehicles, ground, walls and building ceilings.

Description

technical field [0001] The invention relates to a composite disinfectant, in particular to a disinfectant for disinfecting highly toxic military chemicals, and belongs to the technical field of chemical defense. Background technique [0002] Decontamination and disinfection technology is one of the foundations for building chemical defense forces. Strengthening research on decontamination and disinfection technology and developing excellent disinfectants are the key to laying a solid foundation. Traditional military disinfectants, such as the commonly used water-soluble "three in two" (3Ca(OCl) 2 2Ca(OH) 2 The abbreviation) disinfectant, organic system disinfectant "191", etc., play an important role in the disinfection of highly toxic military chemicals, but each has its own shortcomings. Water-soluble disinfectants cannot exert ideal effects on highly toxic chemicals that are difficult to dissolve in water, such as mustard gas (HD), while organic system disinfectants are...
