Technical Field

The invention relates to the technical field of pesticides, in particular to a binary package pesticide aerosol and a preparation method thereof.

Background

The pests such as flies, mosquitoes, cockroaches and the like can not only interfere with the daily life of people, but also become transmitters of infectious diseases, and at present, people commonly use spray type insecticides and heating evaporation type insecticides to kill the pests, and the spray type insecticides and the heating evaporation type insecticides have the advantages of convenience in use, quickness in killing insects and the like. However, the currently used insecticides have the disadvantages of high toxicity, peculiar smell, environmental pollution, small killing area, short time effect, large toxic residue and the like, and with the increasing concern of people on environmental protection and self health, the global insecticide production is beginning to change from the quantitative type to the quality and safety type, and the vigorous development of novel insecticides with high efficiency, low toxicity and safety has become the development direction of the world insecticide industry; furthermore, in summer, the usage rate of the pesticide is very high, the pesticide effect of the aerosol is reduced due to high air temperature, and the pesticide solution is evaporated to damage the respiratory tract of the human body, so that a safer pesticide aerosol is needed.

Disclosure of Invention

The invention aims to solve the defect of poor high temperature resistance in the prior art, and provides a binary package insecticidal aerosol.

In order to achieve the purpose, the invention adopts the following technical scheme:

a binary package insecticidal aerosol is designed, and the formulation of the binary package insecticidal aerosol comprises the following raw materials by weight: 60-80 parts of organic solvent, 30-40 parts of synergist, 2-5 parts of surfactant, 1-2 parts of antioxidant, 5-10 parts of dissolving agent, 2-6 parts of high temperature resistant agent, 1-2 parts of essence and 1-2 parts of pyrethroid.

Preferably, the synergist is synergistic ether or octachlorodiphenyl ether, which can be used in combination with pyrethrin to generate multifunctional oxidase for inhibiting insects to prevent insects from generating drug resistance, and can generate synergistic effect to increase insecticidal effect.

Preferably, the antioxidant is 2, 6-di-tert-butyl-p-cresol, and the 2, 6-di-tert-butyl-p-cresol belongs to an oil-soluble antioxidant, so that the product can be prevented from being oxidized, and the shelf life can be prolonged.

Preferably, the high-temperature resistant agent is zinc stearate or barium stearate, and the zinc stearate or barium stearate can enable the product to have better photo-thermal stability and cannot have weaker drug effect when being used in a high-temperature environment.

Preferably, the pyrethroid is selected from at least one of allethrin, tetramethrin, cypermethrin and deltamethrin.

The invention also provides a preparation method of the binary package insecticidal aerosol, which comprises the following steps;

step 1: mixing the raw materials in a mixing container at normal temperature, stirring, standing for 10-20 min to obtain pesticide aerosol liquid;

step 2: filling the insecticidal aerosol liquid medicine prepared in the step 1 into a bag, and then filling the bag filled with the insecticidal aerosol liquid medicine into a tank body;

and step 3: and (3) inflating a gas between the inner wall of the tank body in the tank body and the bag, and installing a valve on the opening of the tank body when the pressure in the tank body is between 0.1 and 1Mpa, and closing the valve.

The binary package insecticidal aerosol provided by the invention has the beneficial effects that: according to the invention, the high-temperature resistant agent is added, so that the aerosol has better photo-thermal stability, can not have weaker drug effect when used in a high-temperature environment, can not evaporate an organic solvent, and avoids damage to a human body; furthermore, the synergistic agent is used together with pyrethrin, so that multifunctional oxidase for inhibiting insects can be generated to prevent insects from generating drug resistance, and a synergistic effect can be generated to increase the insecticidal effect.
