Problems solved by technology

Due to the use of insecticides in a closed cabin, civil aviation has strict restrictions on aircraft insecticide aerosols. It must be safe to the human body under the premise of high efficiency and broad spectrum, no toxic residues, and sprays. No damage to instruments and body parts, no residual pollutants, no flammable and explosive components, etc., but the common household insecticide aerosols currently on the market are mostly made of volatile ethanol and petroleum base as solvents. The natural pyrethrum and synthetic pyrethroid preparations have the disadvantages of polluting the environment, being flammable, explosive, irritating and unbearable, and they do not have the conditions for use on airplanes, and it is difficult to meet expectations when using them on airplanes Effect

Embodiment 1

[0048] A water-based hygienic insecticide aerosol used in an aircraft cabin is composed of the following raw and auxiliary materials in parts by mass:

[0049] Proparthrin 0.5%;

[0050] D-phenothrin 1%, the active ingredients of proparthrin and d-phenothrin are compatible with each other;

[0051] The synergist is piperonyl butoxide 0.5%;

[0052] Non-ionic surfactant emulsifier: Polyoxyethylene ether 2%, Tween 801.5%, Span 801.5%, polyoxyethylene ether, Tween 80 and Span 80 compounded according to the quantity;

[0053] The antioxidant is 0.01% of BHT di-tert-butyl-4 and 0.09% of methylphenol;

[0054] Penetrant: Azone 0.1%;

[0055] The rest is deionized water added to 100%;

[0056] In this embodiment, the preparation method of the water-based hygienic insecticide aerosol that the corresponding aircraft cabin uses comprises the following steps:

[0057] 1), first put 0.5% proparthrin and 1% d-phenothrin original drug into the preparation kettle in equal parts, add 0.5...

Embodiment 2

[0063] The concentrated microemulsions of several insecticide compositions are listed below, which can be diluted with water to form oil-in-water emulsified sprays. The emulsified microparticles of the active ingredients have a diameter of 5-10nm nanometers, and they are uniformly and stably dispersed in the liquid medicine, with a transparent temperature range -10℃~65℃, maintain the stability of the liquid medicine in the low temperature heat storage environment. Hygienic Toxicology Grade: Slightly Toxic Grade. The formulation of this low VOC and MTR insecticide concentrate is shown in Table 1:

[0064] Table 1

[0065]

[0066] List several insecticide composition concentrates below, can be made into demulsified water-in-oil spray, the formula of this low VOC and MIR insecticide concentrate is as shown in table 2:

[0067] Table 2

[0068]

[0069] The insecticide composition concentrate in this embodiment is also a low-VOC and MRI formulation, and also uses methyl ...

Embodiment 3

[0071] Water-based concentrated microemulsion formulations, combined with 1.5% (quickly knocked down) and 3.5% (long-acting) pyrethroids respectively, are composed of insecticide concentrates (F), (G), ( H), (I) are processed by two-stage homogeneous high-shear emulsifier process. The formula of this water-based concentrated microemulsion preparation is as shown in table 3:

Abstract

The invention provides a water-based hygienic insecticidal aerosol used in an aircraft warehouse and a preparation method of the aerosol. The active ingredient is pyrethrin or pyrethroid; furthermore,the aerosol comprises a synergist, a solvent, an additive and an emulsifier, wherein the solvent is fatty acid methyl ester or fatty acid ethyl ester, the additive comprises a food-grade or natural antioxidant; the emulsified micro-particle diameters of the active ingredient is up to 5-10nm nanoscale, the active ingredient can be stabilized in insecticidal liquid in an evenly dispersed mode, andtransparent temperature ranges are from minus 10 DEG C to plus 65 DEG C; mutual cooperation effects are combined through insecticidal unprocessed pesticide seeds, the toxicological level of hygienic toxicology is reduced, the effective insecticidal effect is enhanced, a chemical structure changes for pharmacology, and pests have difficulty in producing insecticide resistance; the good stability ofthe insecticidal liquid is maintained at various low-temperature heat storage environment temperatures, and the aerosol is easy to use.

Description

【Technical field】 [0001] The invention relates to an insecticide and a preparation method thereof, in particular to a water-based sanitary insecticide aerosol used in an aircraft cabin and a preparation method thereof. 【Background technique】 [0002] With the development of the air transport industry, the airplane as a modern fast transportation tool has greatly shortened the time and space boundaries of human communication, and at the same time provided a shortcut for the spread of vector insects, which may make the infected insects in the epidemic area spread rapidly to all parts of the world . [0003] Therefore, aircraft desinsection, especially to the work of desinsection of incoming aircraft, has been paid more and more attention by the air transport sector. According to the International Air Transport Manual and WHO's requirements for aircraft disinsection procedures, pesticides should be applied after boarding. Due to the use of insecticides in a closed cabin, civi...
