Description
Technical field
The present invention relates to a kind of insect aerosol, especially relate to a kind of dry fog insect aerosol.
Background technology
Insect aerosol is as eliminating and one of the major product of Pest Control, near 2.6 hundred million jars, accounts for more than 40% of the whole aerosol products total amounts of China in the annual production of China.Yet from 20th century the mid-80, China has begun since the suitability for industrialized production insect aerosol, solvent that insect aerosol is used and propellant are mainly with third butane of high boiling solvents such as deodorized kerosine and 30%～50% left and right sides ratio, because the percentage by weight of propellant is not more than 50% of total composition, therefore also have the following disadvantages: 1, owing to cause the ejecta particle relatively large, the easy sedimentation of droplet in use, therefore having reduced flying insect to a great extent drips the chance that contacts with medicine, is unfavorable for killing flying insect.2, owing to the kerosene that stays difficult volatilization after the ejection of this kind insecticide easily is residual, to a certain extent environment for use is polluted.3, because insecticide ejection droplet is more volatile easily by behind the human body suction respiratory tract, also inevitably human body is produced some senses of discomfort.
Summary of the invention
The present invention is directed to the weak point of above-mentioned existence, the mist droplet particle size that the insecticide that a kind of dry fog insect aerosol makes ejection is provided is less than 20 μ m, and not only droplet easily spreads, and uses the no oil stain in back residual, obviously improves insecticidal effect.

A kind of dry fog insect aerosol, it is characterized in that: its component by weight percentage: comprise 0.75% insecticidal active ingredient, 1% synergist, 13.25% alcohols low boiling point solvent and 85% propellant, wherein, described insecticidal active ingredient is 0.35% pyrethroid/and the mixture of 0.40% carbamate, and synergist is an Octachlorodipropyl Ether, the alcohols low boiling point solvent is an absolute ethyl alcohol, and propellant is third butane.
A kind of dry fog insect aerosol, it is characterized in that: its component by weight percentage: comprise 0.75% insecticidal active ingredient, 1% synergist, 8.25% alcohols low boiling point solvent and 90% propellant, wherein, described insecticidal active ingredient is the mixture of the carbamate of 0.35% pyrethroid and 0.40%, and synergist is an Octacide 264, the alcohols low boiling point solvent is an isopropyl alcohol, and propellant is a dimethyl ether.
The preparation method of dry fog insect aerosol is as follows:
A, the preparation of dense material: 0.05%～2% insecticidal active ingredient and 0.5%～3% synergist are mixed the back in the reactor stirring, heating and the dissolving that are lower than 80 ℃;
B, solvent or diluent preparation: the dense material that will prepare and cool off dilutes, mixes with 5%～19% solvent that boiling point is lower than below 100 ℃;
C, solvent or diluent can: solvent or diluent is added in the aerosol jar by liquid filler;
D, plug in valve, seal: ready valve is inserted in the aerosol jar, seal by sealing machine;
E, propellant fill: the liquid propellant with 80%～90% charges in the aerosol jar of sealing mouth by inflator.
F, water-bath leak detection: the aerosol jar that will fill propellant is put into 50 ℃～60 ℃ water bath and is carried out pressure and leak test.
Dry fog insect aerosol of the present invention in use can produce the droplet of particle diameter less than 20 μ m, its atomizing principles is: when insecticide when valve and nozzle system high velocity jet are to air, be ground into droplet with the direct bump of air, after this be included in the liquid propellant in the droplet, owing to the pressure abrupt release of propellant is gasified, the energy that is discharged when making the liquid propellant gasification can further make droplet pulverize, attenuate, especially work as propellant and surpass 80%, its energy that discharges is bigger, faster, simultaneously under the effect of low boiling point solvent volatilization, so can produce the fine mist of mist droplet particle size less than 20 μ m.
The present invention adopts the advantage of technique scheme to be:
1, the present invention adopts the lower boiling easy volatile solvent of alcohols, and the consumption of propellant in the raising insecticide, because of low boiling point solvent volatile in air, and increased the consumption of propellant, realize that the ejection mist droplet particle size is less than 20 μ m, prolong the skyborne sedimentation time of droplet, increased winged insect greatly and dripped the chance that contacts with the insecticide medicine, insecticide efficiency obviously improves 10～15%.
2, insecticide of the present invention adopts lower boiling alcohols solvent, and has replaced conventional oil-based solvent, thus insecticide can not stay the oiliness of difficult volatilization after use residual, can not pollute environment, safe in utilization.
3, adopt dry fog insecticide of the present invention, the droplet of its ejecta is little, volatilization is fast, therefore is difficult for being sucked respiratory tract by human body, has solved insecticide human body is caused uncomfortable phenomenon.
