Description

A water-based insecticide aerosol

technical field

The invention relates to a daily chemical product, in particular to a water-based insecticidal aerosol.

Background technique

Mosquitoes are important sanitary pests in the world, which can harm humans in various ways such as biting and parasitism. The most important thing is that mosquitoes are an important medium for disease transmission. They can spread malaria, plague and other epidemic diseases, which seriously threaten people's lives. In the prior art, oil-based aerosols are mainly used for the prevention and control of mosquitoes, which will leave oil stains on the surface of objects during use and cause serious environmental pollution. There are also hidden dangers in the transportation process. Therefore, provide a kind of environmental protection, safe insecticide aerosol has huge market prospect.

Natural pyrethrins are active ingredients isolated from pyrethrum flowers that have insecticidal effects, and are internationally recognized as safe insecticides.

Wintergreen oil is a plant volatile substance extracted from plants. It not only has the effect of killing insects and bacteria, but also has a special effect of calming the nerves. Tea saponin is a kind of glycoside compound extracted from tea tree seeds (tea seeds, tea seeds), and is a natural surfactant with good performance.

Contents of the invention

The object of the present invention is to provide an insecticidal aerosol with good mosquito control effect, no pollution to the environment and a delicate smell. The specific technical solutions are:

A water-based insecticidal aerosol is characterized in that it comprises the following components: 0.1-5% of wintergreen oil, 0.1-3% of natural pyrethrins, 1-5% of emulsifier, 5-10% of deodorized kerosene, projectile Agent 30-50%, silicone defoamer 1-2%, custard apple extract 0.1-5%, deionized water to make up 100%. The emulsifier is tea saponin; the propellant is propane and/or butane liquefied gas; and the custard apple extract is ethanol extract of custard apple fruit.

The preferred technical scheme of the present invention is 2% of wintergreen oil, 1% of natural pyrethrins, 4% of tea saponin, 8% of deodorized kerosene, 49% of propellant, 1.5% of silicone defoamer, and 0.1% of cherimoya fruit ethanol extract -5%, deionized water makes up 100%.

The extraction method of the ethanol extract of custard apple fruit is as follows: take the cherimoya fruit, crush it, soak it in ethanol for 1 day, the material ratio is 1:3-5 (w/w), then filter to obtain the ethanol extract, and extract it 2-4 times , the concentrated extract is obtained.

The specific preparation method is as follows: according to the ratio of each raw material, according to the conventional production method of insecticidal aerosol, now dissolve pyrethrin in the solvent, add emulsifier, etc., stir, stand still, and obtain after forming a homogeneous solution The aerosol is obtained by putting the obtained aerosol into an aerosol can and pouring it into a propellant.

The beneficial effects of the present invention are:

1. The custard apple extract and wintergreen oil are used to make the product have a certain plant fragrance, and at the same time, it can also play a role in killing insects, killing bacteria and refreshing;

2. In the aerosol of the present invention, the emulsifier is a plant-derived substance, so it will not cause harm to the environment and people;

3. After adding the wintergreen oil and the ethanol extract of custard apple to the aerosol of the present application, it has played a synergistic effect on the mosquito-killing and repelling activity.

Detailed ways

Example 1

Take wintergreen oil 2%, natural pyrethrin 1%, tea saponin 4%, deodorized kerosene 8%, propellant 49%, silicone defoamer 1.5%, cherimoya fruit ethanol extract 0.1-5%, deionized Water makes up 100%.

The extraction method of the ethanol extract of custard apple fruit is as follows: take the cherimoya fruit, crush it, soak it in ethanol for 1 day, the material ratio is 1:4 (w/w), then filter to obtain the ethanol extract, extract 3 times, and concentrate the extract Vested.

The specific preparation method is as follows: according to the ratio of each raw material, according to the conventional production method of insecticidal aerosol, now dissolve pyrethrin in the solvent, add emulsifier, etc., stir, stand still, and obtain after forming a homogeneous solution The aerosol is obtained by putting the obtained aerosol into an aerosol can and pouring it into a propellant.

Embodiment 2: Take 1% of natural pyrethrins, 4% of tea saponin, 8% of deodorized kerosene, 49% of propellant, 1.5% of silicone defoamer, 0.1-5% of cherimoya fruit ethanol extract, deionized water Make up 100%.

The preparation method is the same as in Example 1.

Example 3: Take 2% of wintergreen oil, 1% of natural pyrethrin, 4% of tea saponin, 8% of deodorized kerosene, 49% of propellant, 1.5% of silicone defoamer, and 100% of deionized water.

The preparation method is the same as in Example 1.

The insecticidal effect of the insecticidal aerosol of the present application is shown in Table 1.

Table 1 The insecticidal effect experiment of the insecticidal aerosol of the present application

It can be seen from Table 1 that after adding the ethanol extract of custard apple and wintergreen oil at the same time, the quick-acting property of the aerosol has been significantly improved, and it can be seen that the synergistic effect is mainly on the quick-acting property. Judging from the 24-hour corrected mortality rate, after adding two kinds of plant-derived substances at the same time, the control effect was increased by about 5%, and there was also a certain synergistic effect.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
