Abstract
The invention discloses a domestic controlled-release insecticidal composition, which is applicable to being sprayed indoor or into a closed environment for controlling insects, capable of slowly releasing effective insecticidal constituents, and persistently effective on killing domestic common pathogenic insects such as mosquitoes, flies, dust mites and the like. The invention further provides a disposable aerosol sprayer which releases the composition in a spray form and is convenient in use. The domestic controlled-release insecticidal composition comprises cellulose, palygorskite, essence, betaine type amphoteric surfactant and the like, which are well compounded, particles are further evenly coated by a novel supercritical impact particle coating method so that reunion tendency easily occurring in the conventional means is relieved, uniformity of microcapsules is improved, and common advantages of the existing supercritical coating methods are retained. The domestic controlled-release insecticidal composition is effective in insect killing, and evident in slow release.
Description
Technical field
The present invention relates to a kind of family expenses slowly-releasing Pesticidal combination, relate in particular to a kind of family expenses slowly-releasing Pesticidal combination that comprises the insecticide slow-release microcapsule.Said composition is suitable for being used for through Sprayable the desinsection of indoor and closed environment, and it can slowly discharge insecticidal active ingredient, the lasting effectiveness of killing that keeps for common pathogenic insects of family such as mosquito, fly, dirt mites.
Background technology
The chrysanthemum ester type compound can be used for preventing and treating mosquito, and has higher insecticidal activity, to be widely known by the people.But the existing in the market various liquid that wipes out the flies and mosquitoes sprays during use in indoor, and drug volatilization is fast, and effectively kill pests still because medicine discharges rapidly, and duration of efficacy is very short, needs to spray constantly, makes troubles to the user.Disclose a kind of long-acting concentrated incecticide for soaking and painting use in the one Chinese patent application 95111196, but that this product exists is poisonous, have peculiar smell, effective time still not long, and uses inconvenience.Therefore people need a kind of nontoxic, free from extraneous odour, the insecticide that spraying once just can be permanently effective.
Summary of the invention
The object of the invention just is the deficiency to prior art, and a kind of family expenses slowly-releasing Pesticidal combination of insecticide slow-release microcapsule and disposable aerosol agent injector of using said composition of comprising is provided.
The objective of the invention is to realize through following measure:
A kind of family expenses slowly-releasing Pesticidal combination comprising the insecticide slow-release microcapsule, is characterized in that this insecticide slow-release microcapsule is to make through following method:
1) with cellulose, attapulgite, essence, beet alkali ampholytic surface active agent by 85 parts: 100 parts: 0.5 part: 0.1 part weight ratio joins in 500 parts the acetone soln of 0.1% (wt) chrysanthemum ester amine, obtains mixed liquor 40 ℃～50 ℃ following mixing and stirring;
2) this mixed liquor is placed autoclave, the carbonic acid gas after adding is boosted through high-pressure diaphragm pump in autoclave, heating up also to stir forms suspension;
3) with a pair of nozzle ejection bump of this suspension through coaxial relative placement, the coating microcapsule particle of separating out separates through gas-solid separator with carbonic acid gas and promptly gets the insecticide slow-release microcapsule.
Cellulose wherein can be CMC or hydroxyethylcellulose.
Beet alkali ampholytic surface active agent wherein can be CTFA or 11 carbonamido acetate betains.
As stated; The present invention has used attapulgite as the capsule core component in composition is formed on the one hand; Make full use of its bigger load capacity that specific surface brought, make effective insecticidal agent composition be carried on its surface and inner, not only saved expensive insecticide consumption but also improved the distributional pattern of insecticide; Increase itself and extraneous contacting, help strengthening the effectiveness of Pesticidal combination and continue to discharge.
On the other hand; The present invention has used amphoteric surfactant to attapulgite modified; Promote the load of insecticide ingredient in its surface and gap through improving its oleophylic performance; And improved the even distribution of clad material to a certain extent, and prolong desinsection and renderd a service the time that keeps, improved its wide spectrum adaptability simultaneously for the different solvents medium.
In addition; The present invention is through using advanced overcritical bump particulate method for coating; Further realize the even coating of particle, alleviated the reunion tendency that occurs easily in the conventional means, thereby improved the uniformity of microcapsules; Make product have more outstanding sustained release performance, also have the general advantage of existing overcritical method for coating simultaneously.
Embodiment
Embodiment 1
The preparation of product A: 1) with CMC, attapulgite, cream jasmin france, CTFA by 85 parts: 100 parts: 0.5 part: 0.1 part weight ratio joins in 500 parts the acetone soln of 0.1% (wt) chrysanthemum ester amine, obtains mixed liquor 40 ℃～50 ℃ following mixing and stirring;
2) this mixed liquor is placed autoclave, the carbonic acid gas after adding is boosted through high-pressure diaphragm pump in autoclave is warming up to and forms supercriticality stirring formation suspension;
3) with a pair of nozzle ejection bump of this suspension through coaxial relative placement, the coating microcapsule particle of separating out separates through gas-solid separator with carbonic acid gas, collects the microcapsule particle that separates and promptly gets insecticide slow-release microcapsule product A.
Embodiment 2
The preparation of product B: use hydroxyethylcellulose to replace CMC, use 11 carbonamido acetate betains to replace CTFA, repeat the preparation method of embodiment 1, make product B.
Embodiment 3
Properties of product tests: product A and B are added water respectively, and evenly to be hybridly prepared into the atomized liquid of 0.1% (wt) subsequent use; 30 houseflies alive, 20 anopheles alive are put into each airtight chamber respectively; Use sprayer of the present invention on tank wall, to spray into the atomized liquid of product A and B respectively with spray method, spray value is 5ml.Pick up counting and regularly observed and recorded knock down number of elements after 24 hours, remove the mosquitos and flies in the case, the mosquitos and flies of putting into similar number more respectively after 72 hours is placed in chamber, pick up counting and regularly observed and recorded knock down number of elements after 24 hours.Carry out the blank test simultaneously.The result as follows.
Claims (3)
