Abstract
The invention discloses a preparation method of an indoxacarb-emamectin benzoate water emulsion formula. The formula is prepared through a novel water emulsion technology. Compared with the conventional water emulsion, the provided indoxacarb-emamectin benzoate water emulsion has the advantages of simpleness, rapidness, and simple technology. The solvents are improved, and solvents are compounded so as to achieve the enhancing effect. Moreover, the heat storage stability of the water emulsion is good, the water emulsion will not crystallize under cold storage conditions, and each index of the indoxacarb-emamectin benzoate water emulsion meets the national standards.
Description
Technical field
The invention belongs to pesticidal preparations production technical field, relate to a kind of indoxacarb emamectin benzoate water emulsion formulations preparation method.
Background technology
Indoxacarb emamectin benzoate water emulsion is a kind of novel aqueous emulsion preparation technology be prepared from by new technology aqueous emulsion Process, and under normal temperature and pressure conditions, random ratio all can obtain indoxacarb emamectin benzoate water emulsion formulations.
Indoxacarb emamectin benzoate water emulsion formulations preparation method difficult point is: (1) two kind of former medicine solvent select and the selection of complex solvent: solvent is selected mainly to be to choose solvent and is made good use of complex solvent and selects; If alone a kind of solvation probably can not be dissolved wherein completely, cause final products to occur crystallization, analyse the problem such as oil, bleed, stability is not good.(2) selection of the surfactant in aqueous emulsion and composite use: the composite use of surfactant and cosurfactant improves stability and the emulsibility of preparation to a great extent, choosing surfactant is difficult point place prepared by making indoxacarb emamectin benzoate water emulsion formulations.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of indoxacarb emamectin benzoate water emulsion formulations preparation method
Technical scheme of the present invention is:
A kind of indoxacarb emamectin benzoate water emulsion formulations preparation method, contains by percentage to the quality:
The object of the invention is a kind of indoxacarb emamectin benzoate water emulsion formulations preparation method preparing a kind of difficulty preparation, the present invention have selected special solvent and complex solvent ratio, preparation under the condition of normal temperature and pressure and obtaining, has very large use when preparing indoxacarb emamectin benzoate water emulsion formulations and preparing.
Embodiment
The present invention is intended to protect a kind of indoxacarb emamectin benzoate water emulsion formulations preparation method.
A kind of indoxacarb emamectin benzoate water emulsion formulations preparation method of the present invention by being prepared under special solvent, special solvent ratios and normal temperature and pressure.
In order to make object of the present invention, technical scheme and advantage clearly understand, the following specific embodiment of the present invention is described, but the present invention is limited to absolutely not these examples.The following stated is only the good embodiment of the present invention, only for explaining the present invention, therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with appended claims.
Embodiment 1
