Purposes.
Background technology
Aqueous emulsion agent world code name EW, also referred to as emulsifiable concentrate, are by liquid or former with the liquid pesticidal that solvent is mixed to prepare
The preparation that medicine is dispersed in water with the droplet of 0.5-1.5 microns, outward appearance is milky milk shape liquid.Aqueous emulsion is because using big
The water of amount has saved natural resources as main solvent, is internationally recognized environment-friendly water-based agent type, and auxiliary agent low cost, production sets
It is standby simple, it is one of main formulation of current Agrochemicals.
There are some technical barriers in aqueous emulsion product：1) stabilization time is stored short：The normal period of storage of agricultural chemicals is 2-3
Year, and the aqueous emulsion normal shelf time is 1 year or so；2) easily there is lamination：Can be with the thing of temperature, active compound and auxiliary agent
Reason and the reason such as change, ultraviolet, time, water quality of chemistry and go out to manage breakdown of emulsion, be exactly that water is separated with solvent, formed and be layered；3)
Easily there is deposited phenomenon：Because auxiliary agent and active compound such as decompose at the reason, and cause active compound to separate out from the middle of preparation, formation rice-shaped or
Crystalline material and sink to bottom, greatly reduce the content of product drug effect and active ingredient；4) it is difficult solution pesticide synergistic to ask
Topic：Due to being that, with water as main solvent, the formation of aqueous emulsion is a kind of dynamic stability principle, conventional builder is such as doubled
Kill, vegetable oil, organosilicon, thiophene ketone etc., it is extremely unstable in the formulation, so, the normal formulation surface tension of aqueous emulsion with
Almost, it is maximum problem that adhesion and penetration difference are aqueous emulsions, it is difficult to improve product drug effect for the surface tension of water；5) water
Emulsion easily freezes in winter, and particularly northern China temperature is less than -15 DEG C, significantly limit the development of the formulation.
