Background

The mosquito, fly, cockroach and other pest are harmful to the life health of people, and the control level of the pest is listed as the measure index of the urban civilization degree, even a non-negligible index for measuring the national people's health level. The insecticidal aerosol has the advantages of convenient use and carrying, good storage stability and the like, is a common product for household hygiene insecticidal defense, and has annual sales volume of over billions in China. However, with the stricter regulations of the national government on the safety of the sanitary insecticide, the molecular structure of the efficient insecticide is more complicated to research, the probability of developing a good new insecticide is lower, the development time is greatly prolonged, the development cost is huge, the application of the insecticide is greatly limited, and the defect of weakened insecticidal effect caused by the generation of the drug resistance is difficult to overcome by the insecticide.

At present, most of the insecticidal aerosols on the market are compounded with a plurality of active ingredients to improve insecticidal activity and delay the generation of drug resistance, and particularly, water-based insecticidal aerosols are the hot spots of current research. The water-based insecticidal aerosol is green and environment-friendly, accords with the current environment-friendly concept of energy conservation and emission reduction, and is the mainstream of insecticidal aerosol development in the future. However, the existing commercial production of water-based pesticide aerosols are water-in-oil type, and the liquid phase of the products is divided into two layers when the products are static, the upper layer is a concentrated layer of propane, butane and pesticide effective ingredients, and the lower layer is a water-in-oil emulsion, so that the products have the following problems when in use: because the chemical components of the product are not uniformly distributed, the product must be fully shaken before use; part of the sprayed liquid medicine is emulsion, which affects the use effect of the product; the water-in-oil type water-based insecticidal aerosol has high kerosene content which accounts for about 10% of the total weight, and can generate pungent smell inevitably when in use.

The Chinese patent application with publication number CN 104137852A discloses a water-based household insecticidal aerosol and a preparation method thereof, the insecticidal aerosol is prepared by compounding a plant source insecticide and a pyrethroid insecticide as effective components and adding a surfactant, a corrosion and corrosion inhibitor, a penetrating agent, a solubilizer, a complexing agent, a wetting agent, an antifoaming agent, an excipient and essence, the prepared water-based household insecticidal aerosol is homogeneous and transparent, does not need to be shaken uniformly before use, and has the characteristics of better repellent effect and long-lasting Multifunction (MIK) on mosquitoes, flies, cockroaches, ants, termites, mites, ticks and the like.

Although the prior art has made various efforts to improve the formulation and production process of water-based pesticide aerosols, there still exist many defects, and there are few and few products that can really enter the market and are used by consumers, so there is a need to provide a novel pesticide aerosol and a preparation method thereof to meet the market demand.
