Description

A kind of nimbin and pyrethrin complex microemulsion and preparation method thereof
Technical field
The present invention relates to the technical fields of pollution-free natural plant insecticide microemulsion, particularly relate to a kind of print Chinaberry element and pyrethrin complex microemulsion and preparation method thereof.
Background technology
For the relatively other such as aqueous emulsions of microemulsion liquid insecticide, missible oil liquid pesticide, it is environmental-friendly with it is high Effect has been universally acknowledged.But it prepares microemulsion to require active compound in water to stablize and can just be prepared into microemulsion to be oil-soluble.
Nimbin (AZadirachtin) is a kind of biological insecticides extracted in neem tree benevolence, can be prevented more than 200 Kind of agriculture, woods, storage and indoor sanitary insect pest are universally acknowledged wide spectrum, efficient, less toxic, degradable, noresidue insecticide.
Pyrethrin (PYrthrins) is derived from the biological insecticides of composite family natural plant, containing six kinds of insecticidal activities at Point, pest is not likely to produce drug resistance, has and quickly knocks down the special effective function of pest, can be widely used for agriculture, woods, herds and urban health Control of insect.
Due to the property of nimbin and pyrethrin facile hydrolysis, they are mostly the dosage form supply of missible oil on the market.Especially It is that nimbin is not reported with pyrethrin complex microemulsion.
Invention content
To solve the problems mentioned above in the background art, the purpose of the present invention is to provide a kind of nimbin and Dalmatian chrysanthemums Plain complex microemulsion and preparation method thereof, have efficiently, high stability, solve under the conditions of water base prepare obtained by nimbin with The drug effect of pyrethrin complex microemulsion and the problem of being difficult to ensure of stability, to realize the traditional high poison agriculture of large batch of replacement Medicine and meet environmentally protective with people's life health needs.
To achieve the above object, the technical solution that the present invention takes is:
A kind of nimbin of present invention offer and pyrethrin complex microemulsion preparation method, include the following steps:
Step 1: weight percent accounting 21.2-61% surfactants and weight percent accounting 30-65% low-carbon alcohols are helped Surfactant is uniformly mixed, and group becomes oil phase;
Step 2: being 0.1~3% nimbin by weight percent accounting and weight percent accounting is 0.1~5% pyrethrin It is dissolved among the oil phase obtained by step 1;
Step 3: under 60 revs/min of stirring conditions, by quantitative polishing weight percent be 100% deionized water slowly Be added obtained by step 2 dissolved in the oil phase of nimbin and pyrethrin, and it is uniform, transparent to continue stirring until solution, obtains oil Packet water microemulsion, as finished product.
In above-mentioned technical proposal, low-carbon alcohols cosurfactant includes following components by weight percentage:10~15% Ethyl alcohol, 5~15% isopropanols, 5~15% isobutanols, 5~10% isoamyl alcohol and 5~10% propylene glycol.
In above-mentioned technical proposal, nonionic surfactant includes following components by weight percentage:5~15% agriculture breasts 1601,5~10% agriculture breasts 1602,1~5% polysorbas20,1~5% Tween 80,1~4% organosilicon SiLwet408,5~10% Piperonyl butoxide, 3~10% azones, 0.1~1%BHT and 0.1~1% benzophenone.
The present invention also provides a kind of nimbins and pyrethrin complex microemulsion, include with the following group by weight percentage Point:0.1~3% nimbin, 0.1~5% pyrethrin, 10~15% ethyl alcohol, 5~15% isopropanols, 5~15% isobutanols, 5 ~10% isoamyl alcohol, 5~10% propylene glycol, 5~15% agriculture breasts 1601,5~10% agriculture breasts 1602,1~5% polysorbas20,1~ 5% Tween 80,1~4% organosilicon SiLwet408,5~10% piperonyl butoxides, 3~10% azones, 0.1~1%BHT and 0.1~1% benzophenone, surplus are water.
Further, a kind of nimbin and pyrethrin complex microemulsion include following components by weight percentage: 0.25% nimbin, 1.45% pyrethrin, 10% ethyl alcohol, 10% isopropanol, 10% isobutanol, 5% isoamyl alcohol, 5% the third two Alcohol, 10% agriculture breast 1601,5% agriculture breast 1602,3% polysorbas20,2% Tween 80,2% organosilicon SiLwet408,5% piperonyl Butyl ether, 3% azone, 0.1%BHT and 0.1% benzophenone, surplus are water.
Compared with prior art, the beneficial effects of the invention are as follows:
The present invention allows water phase by micro- in the microemulsion of water-in-oil type using the characteristic that can have " water core " in micro-emulsion systems Ball wraps up, and so that water phase is isolated with the nimbin and pyrethrin being dissolved in oil phase, to prevent nimbin and pyrethrin in water ring Fast hydrolyzing in border, to solve the instability problem of nimbin and the pyrethrin facile hydrolysis in water environment.
Nimbin provided by the invention and pyrethrin complex microemulsion preparation method are simple for process, and gained microemulsion Medicament is stable, efficient, had both played pyrethrin and has killed the delay drug effect for also achieving nimbin to the speed of pest, can extensive use In the control of insect of organic farm products.
