Abstract

The invention belongs to the technical field of healthy disinsection, and concretely relates to an insecticidal aerosol and a preparation method thereof. The insecticidal aerosol comprises, by weight, 0.5-1.0% of a pesticide, 0.5-1.0% of citronella oil, 1-2% of tea saponin, 0.5-1% of polyoxyethylene sorbitan monostearate, 30-40% of a propellent, 1-5% of glycyrrhetinic acid, 20-30% of ethanol and 20-46.5% of water. The insecticidal aerosol has the advantages of small toxic and side effects, effective prevention and control of mosquitoes, flies and cockroaches, and dust mite repelling and killing, and is suitable for households, hotels and other places. The insecticidal aerosol can inhibit bacteria and calm coughs, can effectively alleviate stimulation to the respiratory tract, and is suitable for sensitive people.

Description

technical field [0001] The invention belongs to the technical field of hygienic deworming, and in particular relates to an insecticidal aerosol and a preparation method thereof. Background technique [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, and have a single effect, mainly to suppress and kill mosquitoes, flies, cockroaches, etc., and have no obvious effect on dust mites. At the same time, insecticide aerosols can easily irritate the respiratory tract of sensitive people, thus causing coughing. [0003] Chinese patent CN101554175B discloses a water-based insecticide aerosol, including insecticide, solvent, emulsifier and propellant, wher...
