Description
Technical field
The present invention relates to a kind of vegetable source pesticide aerosol containing nimbin and preparation method thereof.
Background technology
Nimbin, as good Plant antifeedant, has good repellent action to multiple sanitary insect pest, and low toxic and environment-friendly, to person poultry safety, has the potentiality being developed as hygienic insecticide simultaneously.Current azadirachtin preparation product is mainly used in above agricultural, does not also have sending out in nimbin hygienic biocide spray to open, belongs to the market vacancy.
Existing plant source sanitary insecticide kind is single: the sanitary insect pest taking mosquito as representative, by harassing, biting, the various ways harm humans life such as parasitic, and can spread disease cause of disease and the epidemic disease such as the plague, typhoid fever, the life security of serious threat people.Hygienic biocide aerosol and owing to being directly applied in human residential environment, contacts time long with human body, therefore higher to its security requirement.For a long time, the control of sanitary insect pest is mainly used to the pyrethroid pesticide of chemosynthesis, although compared with other chemical pesticides, its toxicity is very low, and Long-Time Service still has potential impact to living environment and health.
The plant source sanitary insecticide of current use, mainly based on natural pyrethrum, the feature due to natural pyrethrum is that knocking down property is strong but the lasting period is short, needs regular Reusability, also can affect to indoor environment when indoor use.
Summary of the invention
The object of the present invention is to provide a kind of vegetable source pesticide aerosol containing nimbin and preparation method thereof, solve the problem that existing insect aerosol effect is undesirable.
To achieve these goals, technical scheme of the present invention is as follows:
Containing a vegetable source pesticide aerosol for nimbin, described insect aerosol is made up of the component of following weight percents:
Nimbin 0.1 ~ 3%
Neem oil 1 ~ 20%
Surfactant 0.1 ~ 3%
Cosolvent 8 ~ 15%
Emulsifier 1 ~ 10%;
Finally, with solvent polishing to 100%.
Particularly, described insect aerosol is the nimbin of 0.3%, neem oil, the surfactant of 0.2%, cosolvent, the emulsifier of 3%, the solvent composition of 83.5% of 8% of 5% by percentage by weight.
Particularly, described insect aerosol is the nimbin of 0.1%, neem oil, the surfactant of 0.2%, cosolvent, the emulsifier of 5%, the solvent composition of 76.7% of 10% of 8% by percentage by weight.
Particularly, described insect aerosol is the nimbin of 1%, neem oil, the surfactant of 1%, cosolvent, the emulsifier of 7%, the solvent composition of 67% of 12% of 12% by percentage by weight.
Particularly, described insect aerosol is the nimbin of 2%, neem oil, the surfactant of 2%, cosolvent, the emulsifier of 4%, the solvent composition of 64% of 13% of 15% by percentage by weight.
Particularly, described insect aerosol is the nimbin of 1.5%, neem oil, the surfactant of 1.5%, cosolvent, the emulsifier of 1%, the solvent composition of 68% of 9% of 19% by percentage by weight.
Particularly, described insect aerosol is the nimbin of 0.8%, neem oil, the surfactant of 0.8%, cosolvent, the emulsifier of 9%, the solvent composition of 76.4% of 10% of 3% by percentage by weight.
Preferred as one, described solvent is eucalyptus oil, mineral oil or turpentine-based vegetable oil.Described cosolvent is isopropyl alcohol or By-120.
Containing a preparation method for the vegetable source pesticide aerosol of nimbin, comprise the following steps:
(1) nimbin and neem oil are dissolved in cosolvent;
(2) add surfactant, emulsifier, solvent, be then stirred well to evenly, obtain aerosol liquid;
(3) aerosol liquid is loaded in aerosol container, and be pressed into propellant under elevated pressure conditions, obtain aerosol products; Wherein be pressed into the temperature of propellant process lower than 54 DEG C.
The present invention compared with prior art, has the following advantages and beneficial effect:
The nimbin that the present invention adopts and neem oil all have natural plant active substance, high-efficiency low-toxicity, noresidue, to human-body safety, and do not pollute indoor environment, meet the green of people to hygienic insecticide, the requirement of environmental protection, be applicable to the health pest control in the places such as inhabitation, office, dining; The processing technology of this product is simple simultaneously, is suitable for batch production.
Solvent of the present invention selects vegetable oil solvent, abandons the solvent of traditional arene; Because carry out the hygienic insecticide that uses in indoor and people and animals time of contact is long and for a long time, traditional aromatic hydrocarbon solvent is comparatively large to people and animals' harm, is not suitable for using in indoor.This formulation product adopts the vegetable oil solvent coming from plant, and low toxic and environment-friendly, and fragrant odour, meet the demand of hygienic insecticide.
