Problems solved by technology

In this invention, deodorized kerosene, solvent oil or asphalt is slowly added to the pyrethrin concentrate, and the obtained oily pyrethrin aerosol effectively reduces the toxicity of the insecticide, but it lacks the necessary propellant, the composition is single, and the atomization effect is excellent. Insecticidal effect is not ideal

Embodiment 1

[0024] First, under the condition of 25°C, 65.8g of benzyl alcohol ester, 2g of piperonyl butyl ether, 1g of polypropylene glycol, 0.2g of allethrin, and 1g of essence were fully mixed in a stirring tank and stirred evenly to prepare a medicinal solution. Then, according to a conventional method, the liquid medicine is poured into the tin can with a filling machine, a valve is inserted and sealed, and 30 g of liquefied petroleum gas is filled into the tin can with a filling machine. Finally, use a water-bath leak detector to conduct a leak test, press the qualified product on the aerosol cap, put it into a box and pack it, and get the insecticidal aerosol. The resulting product number is 1.

Embodiment 2

[0026] First, under the condition of 30°C, 70g of dimethyl phthalate, 5g of piperonyl butyl ether, 2.5g of polypropylene glycol, 0.5g of tetramethrin, and 3g of essence were fully mixed in a stirring tank and stirred evenly to prepare a liquid medicine. Then, according to the conventional method, the liquid medicine is poured into the tin can with a filling machine, the valve is inserted and sealed, and then 19 g of compressed dimethyl ether is filled into the tin can with the filling machine. Finally, use a water-bath leak detector to conduct a leak test, press the qualified product on the aerosol cap, put it into a box and pack it, and get the insecticidal aerosol. The resulting product number is 2.

Embodiment 3

[0028] First, under the condition of 40°C, 76g of diformic acid ester, 3g of piperonyl butyl ether, 5g of polypropylene glycol, 1g of cypermethrin, and 5g of essence were fully mixed in a stirring tank and stirred evenly to prepare a medicinal solution. Then, according to the conventional method, the liquid medicine is poured into the tin can with a filling machine, and the valve is inserted and sealed. Then, the tetrafluoroethane of 10g compressed state is filled in the tin can with a filling machine. Finally, use a water-bath leak detector to conduct a leak test, press the qualified product on the aerosol cap, put it into a box and pack it, and get the insecticidal aerosol. The resulting product number is 3.

Abstract

The invention relates to an insecticide aerosol and a preparation method thereof. The insecticide aerosol comprises the following components in percentage by weight: 60-80 wt% of organic solvent, 10-30 wt% of propellent, 1-5 wt% of potentiating agent, 1-5 wt% of accessory ingredient, 0.2-1 wt% of synthetic pyrethroid and 1-5 wt% of essence. The insecticide aerosol has better atomization and desinsection effect and low VOC content. The preparation method of the insecticide aerosol comprises the following steps: mixing the organic solvent, the potentiating agent, the accessory ingredient, the synthetic pyrethroid and the essence at ratio to prepare a liquid medicine; filling the liquid medicine into a filling container, and sealing; filling the propellent into the filling container; and pressing an aerosol cover on the container to obtain the insecticide aerosol.

Description

technical field [0001] The invention belongs to the technical field of insecticides, and in particular relates to a low-VOC insecticidal aerosol with pyrethroids as active ingredients and a preparation method thereof. Background technique [0002] Flies, mosquitoes, cockroaches and other pests not only interfere with people's daily life, but also become carriers of some infectious diseases. Now people generally use spray type insecticide and heating evaporation type insecticide to kill pests, which have advantages such as easy to use and rapid desinsection. However, the insecticides currently used have disadvantages such as high toxicity, peculiar smell, pollution to the environment, small anti-kill area, short time-effectiveness, and large toxic residues. As people pay more and more attention to environmental protection and their own health, global pesticide production is beginning to shift from quantity to quality and safety, and vigorously developing new pesticides with ...
