From following detailed description, other purpose of the present invention is apparent.
Among the present invention, all percentages if not refer in particular to, are all percentage by weight.Prescription is formed:
Active active ingredient: beta-cypermethrin 0.5-8.6, dtetramethrin (powerful tetramethrin R) 0.5-4.8, d-phenothrin (sumilex R) 0.5-3.9, cosolvent dimethoxym ethane (dimethoxymethane) 1-20, synergist oxidation of piperonyl butoxide (PBO) 5-30, bleeding agent liquid azone 1-8, surfactant alkylbenzene APEO 1-6.5, light and heat are latent to be decided agent liquid and stops organic calcium zinc complexes 0.1-0.8, antifreeze glycol 0.5-6, eliminating smell agent Malodur Conteract is the eliminating smell agent 1-4.5 based on fatty acid of Haarmann and Reimer, antioxidant 264 (food-grade BHT) 0.8-5.6, ultra-violet absorber 2-hydroxyl-4 methoxyl groups-5-diphenylsulfone first copper trihydrate 0.01-0.8, Biocidal algae-killing agent 1227 cationic surfactant 0.05-0.2, antalkaline citric acid 0.2-0.8, emulsifier 4203 (5302) 5-20, aqueous solvent surplus.
Preparation technology of the present invention is easy, and equipment is simple, no specific (special) requirements.
Preparation technology: with active active ingredient: beta-cypermethrin, dtetramethrin, d-phenothrin in having the stainless steel cauldron of agitator with cosolvent dimethoxym ethane stirring and dissolving, after treating fully dissolving, add all above-mentioned formula materials in continuous stirring successively, charging rate is wanted slowly.Low speed stirs, and notes causing mechanical bubble.It is extremely quiet to treat to stir fully the shutdown of all molten back, and bubble complete obiteration after a hour with carrying out can in the milk introducing liquid filling machine that forms, just obtains insecticide of the present invention.
The present invention is described in detail below in conjunction with embodiment.
It is because beta-cypermethrin is made up of efficient one that the present invention adopts beta-cypermethrin to make the desinsection lethal agent.Be that broad spectrum insecticide, insecticidal mechanism are identical with cypermethrin, but biologically active is high 1 times, the delay timeliness phase is long, can be used as the agent of long-acting detention insects.
Dtetramethrin: flying insects such as mosquitos and flies are had very remarkable quick knockdown effect, are to knock down the type active component among the present invention.The insects that creep such as cockroach are had the effect of well driveing, cockroach can be driven away out from hideaway, thereby improved the chance of insect contact medicament.
D-phenothrin: the power of killing is stronger, belongs to killing the type insecticide, and stable performance, lasting effect is also very remarkable.Toxicity is very low, and actual is nontoxic level, is the insecticide that unique allowance is used in civil aircraft in the U.S., also is unique insecticide that is allowed to be sprayed directly on the human body with the control louse in Japan.
Beta-cypermethrin, dtetramethrin, d-phenothrin is wherein 3 compositions that the registered and recommended allowance of national agriculture chemical registration evaluation committee's approved is used for 68 active ingredients of sanitary insect pest insecticide.
The present invention selects for use dimethoxym ethane to make cosolvent, is because it and above-mentioned three kinds of active insecticidal components have and good solubility property and cheap cost, has substituted chlorinated solvents again.Even more important characteristic is that dimethoxym ethane can be taken as and is non-toxic compound, and its aerial maximum acceptable concentration is 1000ppm, or 3100ppm/m
3According to data record at present, still do not have a kind of compound so far so high permissible concentration is arranged in air.According to No. 79/831 literary composition of EEC; About the instruction of dangerous goods, need not force to mark the regulation of its toxicity data to dimethoxym ethane, so dimethoxym ethane is identified as nontoxic, harmless, no burn into is non-stimulated, not carcinogenic, the compound of intoxicating, rustless change not.Be mixed with water, become not so liquid.
Moreover, dimethoxym ethane can also be introduced a large amount of water in prescription, still can keep the premium properties and the storage stability of the composite formula system of chatting, and makes OH group in the water can not destroy the active ingredient of agricultural chemicals.Since water separate into, under the effect of emulsifier, become the water soluble insecticide of definite shape.Because the comprehensive compound action of ergasia, functional eliminating smell agent just can be brought into play the penetrating odor that exists in the elimination system, no longer includes the volatilization of smell gas during use, has played insect protected, desinsection protection environment, safeguards the effect of health of human body.
The present invention adopts oxidation of piperonyl butoxide (PBO) to make synergist, is that it has good safety to people, animal because PBO is the hypotoxicity chemicals.PBO can prolong the validity of pyrethroid; strengthen their stability, pyrethrins and the EXTHIN that exposes in the sun had protective effect, PBO can reduce the decomposition of active ingredient; help to delay the resistance of insect insecticide, prolong the utilization of pesticides life-span.Can make behind the adding PBO and be recovered its insecticidal activity insect by the insecticide of insect generation resistance.When the insect aerobic is dissolved toxic action, when promptly showing resistance, S commonly used
2Synergist is just powerless, does not have tangible synergistic effect, and uses the effect behind the PBO remarkable, has played the consumption that reduces active ingredient, has strengthened insecticide efficiency.
The above-mentioned effect of PBO; prolong the light sensitization of insecticide active substance and the protective effect under the sunlight; under the synergy of other stabilizing agents of this insecticide; just can make insecticide of the present invention be trapped in spray on the position of various materials of (being coated with); or on the metope of alkaline material, do not flow, under hot environment, sunlight and artificial ultraviolet long-term irradiation condition to air; insecticide active substance still can keep the insecticidal effect of several months, thereby reaches long-acting purpose.
The present invention selects for use the liquid azone to make bleeding agent; be because azone is a kind of high osmotic agent, helps the effect of oozing certainly that blends extremely strong; can change the microcosmic proterties of insect organism epidermal cell film; cause the protection barrier action on organism surface to reduce rapidly, insecticidal activity is penetrated in the body, improve the penetrating ability of drug effect; strengthen the drug effect that causes death; reduce the consumption of active insecticidal components, delay resistance and the life cycle of insect, improve insecticidal effect.
The purpose of the surfactant that the present invention adopts is surface tension and the liquid interfacial tension that requirement can significantly reduce solvent (referring to water), and have certain hydrophilic and oleophilic feature and special absorption property required.
The application purpose of light and heat stabilizing agent, antifreezing agent, eliminating smell agent, antioxidant, ultra-violet absorber, Biocidal algae-killing agent, antalkaline and role, can be the concrete measure that helps to improve the high comprehensive performance of the insecticide of chatting and guarantee to be detained the prolongation of effective time as its name suggests.The chemical stability of the active insecticidal components of insecticide particularly of the present invention after use comprises the degraded and the decomposition that delay or prevent active ingredient.
