Abstract
The invention relates to a sulfuryl fluoride compounding agent for efficiently killing bacteria, insects and mice, and a preparation method thereof. The compounding agent mainly comprises the following components in part by mass: 10 to 30 parts of sulfuryl fluoride, 1 to 5 parts of dcyphenothrin, 5 to 10 parts of methyl isothiocyanate, 5 to 15 parts of dimethyl disulfide, 40 to 80 parts of carbon dioxide, and 20 to 50 parts of nitrogen. The compounding agent is prepared by sequentially loading the components into a pressure container according to the vapor pressure from low to high. The sulfuryl fluoride compounding agent can be applied to the fields of health quarantine, plant quarantine, warehousing, soil disinfection, cultural relic and the like, is low in cost, has a broad application range and low poisoning danger, and meets national environmental protection requirements.
Description
Technical field
The present invention relates to a kind of efficient sterilization, desinsection, the sulfuryl fluoride compounding agent killing mouse and preparation method thereof.
Technical background
At present stifling desinsection, the deratization fumigant used is mainly methyl bromide, oxirane, phosphine, dichlorvos and vikane etc.Well-known Celfume is as a kind of available gas insecticide fumigation agent, because its ODP is 0.6, belong to the ozone-layer depleting substance (ODS) that must eliminate of Montreal Protocol regulation, developed country all will eliminate before in January, 2005, and developing country also all will eliminate before 2015.Phosphine severe toxicity, and grain storage pest creates pesticide resistance to phosphine, and indivedual worm kind can not be administered effectively fast, and this seriously constrains the fumigant insect killing performance of phosphine, and stifling rear residue needs buried process.Dichlorvos toxicity is large, not only affects people and animals' cental system, and has potential damage to liver, therefore should control to use.
Disinfectant oxirane due to its single use inflammable and explosive, boiling point high (only 10 DEG C), Long Term Contact has carcinogenic impact, by many countries be classified as control use material.And vikane is as a kind of efficient gas insecticide fumigation agent, its ODP is 0, and noresidue, belongs to environment-friendly products, and EPA has been classified as the important substitute of Celfume.But vikane is higher as fumigant single use expenses for medicine, and report point out vikane potential cause 4780 times that warm effect is carbonic acid gas, therefore its consumption should control.Meanwhile, dwell many for various harmful insect, rodent and pathogenic bacteria are always mixed, there is not selectivity, according to the synergy principle of different agents, need to prepare sulfuryl fluoride compounding agent, make pharmacy effect wide spectrum quick, low toxicity, environmental protection, to strengthen its market competitiveness.
CN02114856.2 reports a kind of desinsection, kills mouse, the formula of disinfectant probed into the using method of said preparation, and its formula is d cyphenothrin 1-10%, oxirane 5-50%, vikane 10-74%, carbonic acid gas 20-60%.Be 25% in the formula ethylene oxide accounting of embodiment, vikane is 42%.Because these two kinds of compositions all have certain toxicity, its consumption is still bigger than normal.
CN200810182984.4 discloses multiple vikane formula, but wherein the consumption of vikane is bigger than normal, and most formula is containing 1,2-dichloro-benzenes.Because 1,2-dichloro-benzenes has high excitant, to swallow and suction has moderate toxicity, therefore may produce considerable influence to environment.
Summary of the invention
The object of the present invention is to provide a kind of cost low, the scope of application is wide, and toxic hazard is little, meets the sulfuryl fluoride compounding agent of national requirements for environmental protection.
Sulfuryl fluoride compounding agent provided by the invention comprises following composition: the vikane of 10-30 mass parts, the d cyphenothrin of 1-5 mass parts, the methyl-isorhodanate of 5-10 mass parts, the Methyl disulfide of 5-15 mass parts, the carbonic acid gas of 40-80 mass parts and the nitrogen of 20-50 mass parts.
The present invention is by repeatedly groping test, and the above-mentioned formula of unexpected discovery can be effective to sterilization, desinsection and kill mouse.Vikane in the present invention is stifling property insecticide, and its low boiling (-55.2 DEG C) and high vapour pressure can form steam by liquid state rapidly at normal temperatures; Methyl-isorhodanate and vikane are different with the killing effect of insect to nematode, fungi, bacterium, but both conbined usage are to killing nematode and fungi has obvious synergistic effect, thus it is lower that dosage is comparatively used alone, safer and environmental protection; And d cyphenothrin has broad-spectrum insecticidal activity to insect, Methyl disulfide to nematode in soil, reaping hook belongs to disease fungus and weeds have good control efficiency.Carbonic acid gas and nitrogen add the effect of intermixture, are substituted epoxy ethane on the one hand and the collaborative aerosolization effect supplementing vikane, but itself have to insect and mouse the effect of dying of asphyxiation.
The present invention utilizes intermiscibility between each component and synergy effect, the special state conversion of energy that the suitable vapour pressure that the mixed fumigation agent nationality finally obtained is had and boiling point are formed, can gasify after impressed pressure is removed and discharge fine particle, these particles have excellent diffusion permeability, to penetrate into rapidly in confined space gap and handled thing everywhere inner, remove with insect, mouse and bacterium, make it suffocate or inhalation poisoning lethal.
Fumigant provided by the invention has broad spectrum activity feature, just can kill sanitary insect pest with same dose single treatment simultaneously, animals and plants insect, forestry pest, soil pests and storage pest etc., can mouse be killed again, be particularly suitable for the disinfestation and deratization process that each class pest and mouse mix container and all kinds of airtight place of dwelling and hiding.In addition, research finds, sulfuryl fluoride compounding agent of the present invention also can be used as soil fumigant and effectively kills nematode in soil, soil-borne disease fungal pathogens, weeds and soil insect etc., and excellent effect is easy to use.
Fumigant provided by the invention is avoided using traditional highly toxic 1,3-dichloropropylene, chloropicrin and inflammable and explosive carcinogenic substance oxirane etc., and toxic hazard is little, and not containing flammable and explosive substance and carcinogenic substance, harmless atmospheric ozone layer, meets environmental requirement.The built agent of gained of the present invention normally can use at-35 ~ 45 DEG C, and not by the restriction of environmental temperature, and played the synergistic effect of each medicament, reduce cost, the wide model of the scope of application, is thus better than existing fumigant formulation.
Present invention also offers a kind of preparation method of above-mentioned sulfuryl fluoride compounding agent, by the vikane of 10-30 mass parts, the d cyphenothrin of 1-5 mass parts, the methyl-isorhodanate of 5-10 mass parts, the Methyl disulfide of 5-15 mass parts, the carbonic acid gas of 40-80 mass parts and the nitrogen of 20-50 mass parts sequentially load pressure vessel from low to high successively according to vapour pressure.
The present invention prepares sulfuryl fluoride compounding agent by the method for physics mixture, its technological process as shown in Figure 1, each component is transported in pressure vessel by filling apparatus (as pump), and in pipeline, residual air/remaining agent recycles, and realizes safety, environmental requirement.
The sulfuryl fluoride compounding agent using method prepared is fumigating concentration is 10 ~ 70g/m
3, fumigation time is 12 ~ 72h.Sulfuryl fluoride compounding agent invention effect of the present invention is rapid, and once-through operation can reach desinsection simultaneously, kills mouse, 100% effect of virus killing process, can be applicable to the fields such as health quarantine, plant quarantine, storage, soil disinfection, historical relic.
