Abstract
The invention relates to a pesticide preparation, and especially relates to a diafenthiuron suspension agent. The agent provided by the invention adopts a dimethyl carbonate solvent. The diafenthiuron suspension agent has the advantages of low production energy consumption, and high efficiency. The diafenthiuron suspension agent is clean, environment-friendly, and green.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, relate in particular to a kind of diafenthiuron suspending agent.
Background technology
Be applied to now the methyl oleate of diafenthiuron suspending agent solvent because source is unstable, and part producer has also added some animal raw fat compositions therein therein, cause methyl oleate quality unstable, under cryogenic conditions, there are a large amount of solidss to analyse and cause the huge increasing of viscosity of solvent, and then affected normally carrying out of production and processing, while carrying out production and processing in the winter time, must in drying room, will after methyl oleate bakingization, just can feed intake, during consumption energy consumption.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide a kind of diafenthiuron suspending agent that energy consumption is little, efficiency is high, clean environment firendly is green that has.
The technical solution used in the present invention is for this reason: described suspending agent is comprised of the component of following percentage by weight:
| The former medicine of diafenthiuron | 50%~60% |
| Dispersant | 3%~10% |
| Thickener | 0.3 -3% |
| Defoamer | 1%-3% |
| Antifreezing agent | 1%~5% |
| Dimethyl carbonate solvent | 5%~10% |
| Water | Complement to 100% |
Described dispersant is selected from modified sodium lignosulfonate, MODIFIED LIGNOSULPHONATE, acrylic acid-maleic acid copolymerized macromolecule sodium salt, one or more in Abietyl modified phosphoric acid ester sodium.
Described thickener is selected from one or more in xanthans, aluminium-magnesium silicate, gum Arabic.
Described defoamer is selected from polyethers emulsion or organic silicon emulsion two kinds or all.
Described antifreezing agent is selected from one or more in ethylene glycol, propane diols or urea.
Dimethyl carbonate (Dimethyl Cabonate) abbreviation DMC is a kind of water white transparency during normal temperature, omit scent of, micro-sweet liquid, 4 ℃ of fusing points, 90.1 ℃ of boiling points, density 1.069 g/cm3, are insoluble in water, but immiscible organic solvent that can be nearly all with alcohol, ether, ketone etc.DMC under normal pressure and methanol azeotropic, 63.8 ℃ of azeotropic temperatures.DMC toxicity is very low, in 1992, just by Europe, classified as nontoxic product, it is a kind of environmental protective type chemical raw material that the modern times " cleaning procedure " require that meets, DMC has good solubility property, and it is molten, boiling spread is narrow, and surface tension is large, viscosity is low, medium circle electric constant is little, has higher evaporating temperature and evaporation rate faster simultaneously, therefore can be used as low poison solvent for coatings industry and pharmaceuticals industry.DMC not only toxicity is little, also have that flash-point is high, steam forces down with air in LEL high, be therefore the green solvent that integrates spatter property and safety.
Dimethyl carbonate solvent forms more single than the conventional methyl oleate in present oil-suspending agent, good fluidity is lower than the viscosity of methyl oleate at low temperatures, and during as oil-suspending agent processing batching, viscosity is little, grinds resistance little, and energy consumption is little, and efficiency is high.
