Problems solved by technology

[0002] Existing insecticidal aerosols are generally oil-based insecticidal aerosols with kerosene as a solvent, which will leave an unpleasant kerosene smell indoors after spraying, and the sprayed droplets are easy to leave on the surface of objects. Oily traces will pollute the environment, therefore, oil-based insecticide aerosols are not conducive to environmental protection
Existing water-based insecticide aerosol, as Chinese invention patent CN1513323 just discloses a kind of water-base insecticide aerosol, it is solvent with a small amount of deodorized kerosene and a large amount of deionized water, and contains emulsifier sorbitan Monooleate and polyoxyethylene sorbitan oleate, silicone defoamer and propellant propylene, butane mixed liquefied gas, this water-based insecticide aerosol, although the content of kerosene in the solvent is reduced However, it still accounts for 5-6% of the total weight of the aerosol, and there is still a certain kerosene smell and oil stains after the aerosol is sprayed, which is not environmentally friendly enough

Abstract

The invention relates to environmental-friendly water-base pesticide aerosols which contain pesticide, solvent, emulsifier and propellant, wherein the pesticide is tetramethrin, detrorotation cyphenothrin and rich-d-t-prallethrin, the solvent is normal paraffin and de-ionized water, the emulsifier is sorbitan monooleate and polyoxyethylene sorbitan monooleate, and the properllant is dimethyl ether. The pesticide aerosols take water as the main solvent and use a small amount of normal paraffin to dissolve the organic matters such as tetramethrin, detrorotation cyphenothrin and rich-d-t-prallethrin, and the solvent has no kerosene, smelly kerosene smell does not remain in the room after spraying, and the sprayed aerosol drop cannot leave oily mark on the surface of objects. Compared with the prior art, the environmental-friendly water-base pesticide aerosols are more environmental-friendly.
