A kind of functional smoke agent for hot fogging machine and preparation method thereof
Technical field
The present invention relates to the efficient field of dispersions of agricultural chemicals, specifically a kind of functional smoke agent for hot fogging machine and preparation method thereof.
Background technology
The operation principle of the hot mist machine of usefulness is in the market: produce the air-flow of HTHP by fuel combustion with agricultural chemicals and farm chemical carrier gasification, reduces heat again after vapour spray enters atmosphere from jet pipe, liquefy rapidly or be solidified into micro-size particles, and form aerosol with air, this pastille aerosol just deposits when the layer of plants diffusion runs into plant and invests in order the surfaces such as leaves of plants, stem, thereby reaches the purpose of control plant pest.
Use hot mist machine to carry out the dispenser operation many-sided advantage is arranged: the one, operating efficiency is high, as only needing 1min to get final product with average every mu of Prochloraz smoke agent control sclerotinia rot of colza; The 2nd, the penetration power of hot mist is stronger, thereby effective ingredient is more evenly distributed in crop canopies, and drug effect is more stable, and can reduce dosage; The 3rd, medication is few, and is lightweight, and little field (below the 3 mu) operation of need not going to the field, thereby greatly alleviates dispenser personnel's labour intensity.
But smoke agent commonly used maybe can have by the agricultural chemicals that hot mist machine is used the major defect of three aspects in the market: the one, because without specially treated, the hot mist of ejection is lower because of density, diffuse into atmosphere to the upper strata easily, also fly away with the wind easily, thereby cause control efficiency decline and cause environmental pollution, usually be only suitable in tall and big plant such as forest pest control, or be only suitable for using in relatively airtight space such as the places such as warehouse, greenhouse; The 2nd, because hypotoxicity smoke agent commonly used is machine oil, vegetable seed wet goods at present, they are poor with most of agricultural chemicals compatibilities commonly used in the market, or incompatible, the pastille liquid of preparing is inhomogeneous heterogeneous body or even stratified liquid, they are difficult to guarantee that formed hot mist is the uniform aerosol of pastille, thereby cause control efficiency bad, also produce easily poisoning, so most agricultural chemicals can not directly come dispenser with hot mist machine in the market; They are three years old, most of liquid pesticides in the market all are comprised of a large amount of lower boiling surfactants, solvent etc., when directly using with hot mist machine, it is easily on fire that these solvents and surfactant are met heat, has greater risk when being used for forest pest control, causes simultaneously the further rising of temperature owing to burning, the easy decomposition failure of active ingredient, the surfactant consumption of also burning itself, thus do not reach due control efficiency, and cause secondary environment to pollute.
