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, particularly relate to a kind of diafenthiuron suspension agent.
Background technology
Be applied to now the methyl oleate of diafenthiuron suspension agent solvent because source is unstable, and part producer also with the addition of some animal raw fat compositions wherein wherein, cause methyl oleate quality unstable, a large amount of solids is had to analyse and cause the huge increasing of the viscosity of solvent under cryogenic, and then have impact on normally carrying out of production and processing, must just can feed intake after methyl oleate bakingization in drying room, during consumption energy consumption when carrying out production and processing in the winter time.
Summary of the invention
The present invention is directed to above-mentioned defect, object is that providing a kind of has the diafenthiuron suspension agent that energy consumption is little, efficiency is high, clean environment firendly is green.
The technical solution used in the present invention is for this reason: described suspending agent is made up 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 two kinds or whole in polyethers emulsion or organic silicon emulsion.
Described antifreezing agent is selected from one or more in ethylene glycol, propane diols or urea.
Dimethyl carbonate (Dimethyl Cabonate) is called for short DMC, is a kind of water white transparency, slightly smell, micro-sweet liquid during normal temperature, fusing point 4 DEG C, boiling point 90.1 DEG C, density 1.069 g/cm3, is insoluble in water, but immiscible organic solvent that can be nearly all with alcohol, ether, ketone etc.DMC at ambient pressure and methanol azeotropic, azeotropic temperature 63.8 DEG C.DMC toxicity is very low, just non-toxic product is classified as by Europe in 1992, it is the environmental protective type chemical raw material that one meets modern times " cleaning procedure " requirement, DMC has excellent 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 for coatings industry and pharmaceuticals industry as low poison solvent.DMC not only toxicity is little, also has that flash-point is high, steam forces down and LEL high in air, is therefore the green solvent integrating spatter property and safety.
Dimethyl carbonate solvent is more single than the conventional methyl oleate composition in present oil-suspending agent, and good fluidity is lower than the viscosity of methyl oleate at low temperatures, and little as viscosity during oil-suspending agent processing batching, grinding resistance is little, and energy consumption is little, and efficiency is high.
