Description
Technical field
The present invention relates to a kind of pesticide emulsion in water and preparation method, belong to agrochemical field.Specifically one kind contains
There is aqueous emulsion of pyrethrin pesticide and preparation method thereof.
Background technology
In the various formulations of current chemical pesticide, aqueous emulsion is most one of formulation of " green " characteristic, and aqueous emulsion is again
Claim agriculture breast liquid or thick emulsion, be a kind of oil-in-water (o/w) mixed system with water as continuous phase, by add suitable auxiliary agent and
Special processing technology, makes oil phase be evenly distributed in aqueous phase with fine particles.Particle diameter typically between 0.1-1 micron, outward
See and be usually milky white liquid, put into and in water, have preferable emulsifying dispersivity.Because aqueous emulsion is heterogeneous liquid, this just determines
In development process, solve the problems, such as that stability is to first have to consider.One excellent formula needs various auxiliary agents to be joined
5, and to have good concertedness,.But want to develop applicable aqueous emulsion product, in the urgent need to materialogy, biology,
The multi-disciplinary close fit such as botany, prevention and control of plant diseases, pest control,
It is not right that water and milk agent aid selects, and controlling of production process is bad, and the product preparing is in long storage process
In wild effect easily occurs, such as: bleed, condensate oil, separate out precipitation and breakdown of emulsion, have a strong impact on the value of product, cause simultaneously
The waste of agricultural chemicals and the pollution of environment；Most water and milk agent producing process is required for adding high energy when preparation at this stage
Amount, such as high speed shear, ultrasonic emulsification etc., this will also result in investment and cost of equipment is high.The present invention prepares pesticide emulsion in water, selects
Suitable auxiliary agent, is uniformly mixed the aqueous emulsion product that just can obtain steady quality, shelf-stable, and technological process of production letter
Single, investment is low with cost of equipment.
