Problems solved by technology

For many years, the application of pyrethroid compounds in household sanitation insecticides has been fully affirmed for their excellent insecticidal activity and low toxicity to humans and animals. However, the existing technology makes this advantage not available in the final product. fully manifested
At present, the existing hygienic insecticide products in the domestic market are mainly mosquitoes, fly incense, aerosol insecticides, electric heating mosquito coils and electric liquid mosquito coils. Although these products are effective in repelling flies and mosquitoes, they are safe to use. Defects such as environmental impact, waste of resources, single prevention effect, and high cost of use are also obvious, especially the safety of mosquito and fly incense burning, the waste of resources in aerosols, and the impact of organic solvents on the home environment are also well known

preparation Embodiment 1

[0033] This embodiment consists of trans-thrinthrin (A), emulsifier, cosolvent, stabilizer, plant essential oil and deionized water. The emulsifier is alkylbenzene sulfonate and alkylphenol polyoxyethylene ether, styrylphenol polyoxyethylene ether, the cosolvent is ethanol, propanol, hexanol, etc., acetone, cyclohexanone, and the stabilizer is ethylene glycol Alcohol, propylene glycol, urea, glycerin, plant essential oils are citronella oil, lemon oil, sweet orange oil, clove oil, wintergreen oil. The percentage by weight of the above components is: 0.5% of trans-permethrin (A), 4.0% of emulsifier, 3.0% of cosolvent, 1.5% of stabilizer, 0.5% of plant essential oil, and 100% of deionized water. Preparation method: Dissolve the original drug of permethrin in cosolvent, add emulsifier, add stabilizer, stir evenly, slowly add remaining water, then add plant essential oil and stir until homogeneous transparent liquid, that is, 0.5% Water-based sanitation insecticide (A).

preparation Embodiment 2

[0035] This embodiment consists of cis-permethrin (B), emulsifier, co-solvent, stabilizer, and deionized water. The emulsifier is alkylbenzene sulfonate and alkylphenol polyoxyethylene ether, styrylphenol polyoxyethylene ether, the cosolvent is ethanol, propanol, n-hexanol, etc., acetone, cyclohexanone, and the stabilizer is ethylene glycol Alcohol, Propylene Glycol, Urea, Glycerin. The weight percentages of the above components are: 1.0% of cis-permethrin (B), 6.0% of emulsifier, 5.0% of cosolvent, 2.0% of stabilizer, and 100% of deionized water. Preparation method: Dissolve the original drug of permethrin in cosolvent, add emulsifier, add stabilizer, stir evenly, slowly add the remaining water, stir fully until it is homogeneous and transparent liquid, that is, 1.0% water-based sanitation Insecticides (B).

preparation Embodiment 3

[0037] This embodiment is composed of permethrin (cis-trans ratio 40; 60) (C), emulsifier, co-solvent, stabilizer, plant essential oil and deionized water. The emulsifier is alkylbenzene sulfonate and alkylphenol polyoxyethylene ether, styrylphenol polyoxyethylene ether, the cosolvent is ethanol, propanol, hexanol, etc., acetone, cyclohexanone, and the stabilizer is ethylene glycol Alcohol, propylene glycol, urea, glycerin, plant essential oils are citronella oil, lemon oil, sweet orange oil, clove oil, wintergreen oil. The weight percentages of the above components are: 10% of permethrin (C), 18% of emulsifier, 12% of cosolvent, 5% of stabilizer, 10% of plant essential oil, and 100% of deionized water. Preparation method: Dissolve the original drug of permethrin in cosolvent, add emulsifier, add stabilizer, stir evenly, slowly add the remaining water, then add plant essential oil and stir until it is homogeneous and transparent liquid, that is, 10% Water-based sanitation ins...

Abstract

The invention belongs to the field of hygienic insecticide, and discloses a preparation method for a hygienic insecticide. The hygienic insecticide comprises an active ingredient, namely chlorempenthrin, and an emulsifier, a co-solvent, a stabilizing agent, pH essential oil and water are added. The preparation method of the insecticide comprises the following steps: firstly, mixing and stirring the chlorempenthrin, the emulsifier, the co-solvent and the stabilizing agent at parts by mass, then adding missible oil into water while stirring, and finally, adding the essential oil and uniformly mixing till the mixture is clear and transparent. The water-based hygienic insecticide replaces an organic solvent with water, does not contain a propellant, is low in manufacturing cost, convenient in operation and high in production, storage and transportation security, and can take better fly whipping and mosquito killing effects in household life in comparison with the prior art.

Description

technical field [0001] The invention relates to an insecticide for killing hygienic pests, in particular to a water-based hygienic insecticide and a preparation method thereof. Background technique [0002] With the continuous improvement of the living environment of urban and rural residents and the improvement of living standards, people have also put forward new requirements for the performance of household sanitary insecticide products. Sanitation insecticide products that are safer and more convenient to use, have less impact on the environment, and are cheaper. For many years, the application of pyrethroid compounds in household sanitation insecticides has been fully affirmed for their excellent insecticidal activity and low toxicity to humans and animals. However, the existing technology makes this advantage not available in the final product. be fully manifested. At present, the existing hygienic insecticide products in the domestic market are mainly mosquitoes, fl...
