Abstract
The present invention provides a smoke agent composite, containing (wt%) active pesticide 5-30%, oxidant 15-35%, reducing ageng 25-35%, flame-eliminating agent 5-10% and the rest is inert filler. Said invention also provides its preparation method, and a through hole type smoke agent.
Description
The present invention relates to pesticidal preparations and preparation method thereof, particularly fumicants and preparation method thereof.
In various pesticidal preparations, fumicants is used widely because of it imposes on the target time and labour saving with active agricultural chemicals.Particularly in greenhouse, storage,, fumicants need not add the undue humidity that water has avoided implementing the space owing to using.
Fumicants is in the process of being fuming, and one of most important technology is that active ingredient is changed into cigarette, and this just requires in the combustion process naked light to be arranged.Prior art is controlled to the cigarette rate by the kind or the amount of selective oxidation agent, but can not reach well-content effect.
The present invention provides a kind of fumicants composition of novel form for solving shortcoming of the prior art.
The invention provides a kind of smoke agent composition, wherein contain the active agricultural chemicals of (by weight) 5-30%, the oxidant of 15-35%, the reductant of 25-35%, the blast reducer of 5-10%, and inert material.
Of the present invention also providing prepares above-mentioned fumicants method for compositions, comprises each component of above-mentioned fumicants and the water that accounts for its gross weight 10-20% are mediated under cooling oven dry then.
It is another purpose of the present invention that the through-hole type fumicants is provided.
In fumicants composition of the present invention, active agricultural chemicals is not specifically limited, and comprises bactericide, insecticide.Insecticide such as organic Phosphorus, pyrethroid, carbamates etc., and other various types of agricultural insecticides.
The object lesson of insecticide has phenylate azole, dicarboximide class, benzamides, imidazoles, triazole type, morpholine class etc.
The concrete example of above-mentioned active agricultural chemicals comprises thiophanate methyl, SP 751011, Methomyl, pyridaben, Amitraz, triazolone, Triadimenol, dichlorvos, chinomethionat, carbendazim, metalaxyl, chlorobenzene azoles pyridine alcohol, prochloraz, Flusilazole, nitrile bacterium alkene, morpholide, difoltan, captan, Euparen, Profenofos, tetramethrin, cypermethrin, decis etc.
Above-mentioned active component can be used for fumicants composition of the present invention separately or with combining form, accounts for the 5-30% of whole fumicants gross weight usually.
In the fumicants composition, oxidant is necessary composition, it accounts for the 15-35% of whole fumicants weight usually, described oxidant is those that use always in this area, for example, chlorate, hypochlorite, perchlorate, nitrous acid or nitrate are in these salt, preferred its sylvite or the sodium salt of using, these oxidants can be used alone or in combination.
Also comprise reductant in the fumicants composition of the present invention, its content accounts for the 25-35% of whole fumicants weight usually, and the preferred feedstock of making reductant in the present invention is a starch, and starch both can make reductant, can be used as binding agent again.
Contain blast reducer especially in the fumicants composition of the present invention, it can guarantee that whole fumicants does not have naked light and produces in dispose procedure, improves into the cigarette rate, that is improves the service efficiency of fumicants.
In the present invention, blast reducer is selected from the carbonate or the bicarbonate of the carbonic acid gas of emitting under the fumicants operating temperature, and the carbonic acid gas that is discharged can reach the above-mentioned purpose that does not produce naked light at work.Therefore the amount of blast reducer is most important to fumicants of the present invention.Usually, in fumicants composition of the present invention, the amount of blast reducer accounts for the 5-10% of whole fumicants gross weight.Light magnesium carbonate preferably is used among the present invention.
Also can contain inert material in the fumicants composition of the present invention as filler.Described inert material is conventional those that use in this area, in the present invention, preferably uses talcum powder.
The present invention prepares in the process of above-mentioned fumicants, and each component under cooling, is added water and mediates mixed medicine, and then oven dry, and organic solvent commonly used mixes medicine in the prior art.Use method of the present invention can guarantee finished product process safety, and reduce to pollute.
Particularly, the present invention prepares the fumicants method for compositions and comprises: each constituent is added water mediate under cooling in kneader, oven dry then.If be processed into certain shape, then can after kneading, be pressed into various forms of fumicants, then oven dry.As make pulvis, then after kneading, directly enter baking step.Described oven dry is preferably carried out under 80-90 ℃.
Fumicants composition of the present invention can be made various forms of fumicants, as pulvis, bar-shaped, particle or through-hole type fumicants.In the present invention, preferred fabrication becomes through-hole form.
It is another purpose of the present invention that the through-hole type fumicants is provided.
According to the through-hole type fumicants, it is made into the form that two is fuming, and promptly forms a through hole in the middle of cylindrical, like this, after the fumicants composition ignited, cigarette can be from the two ends ejection of through hole.Ignition powder can be in the two ends or the centre of whole powder column, and when using, lead-in wire (embedding in the ignition powder) is lighted ignition powder, cause fumicants thereafter, because through hole is arranged in the middle of the fumicants, ignition powder is lighted fumicants rapidly along the through hole section, and whole fumicants is burnt rapidly and discharge the cigarette that contains active ingredient.In the present invention, ignition powder can use those that use always in this area.
Thereby fumicants composition of the present invention has safe, rapid, effective characteristics, compared with prior art has obvious improvement.
Further set forth the present invention below in conjunction with specific embodiment.
