Antifreezing agent is one or more the mixing in ethylene glycol, propane diols, glycerine, the diethylene glycol.
Butyl ether urea method for producing aqueous emulsion provided by the invention is: the butyl ether urea is dissolved in solvent and the cosolvent, adds emulsifier, wetting agent, stabilizing agent and dispersant again, make oil phase; Antifreezing agent mixed obtaining water with deionized water, under shear conditions, oil phase slowly joined aqueous phase or water is slowly joined in the oil phase, make butyl ether urea aqueous emulsion.
Butyl ether urea aqueous emulsion provided by the invention has the following advantages.
1, butyl ether urea aqueous emulsion provided by the invention substitutes most organic solvent with deionized water; reduce environmental pollution; help ecological environmental protection; also can reduce production costs greatly, save a large amount of petrochemical industry resources, and adopt the solvent of low toxicity; significantly reduce organic solvent to the pollution of human body and environment and residual; produce pollution, explosive and poisoning problem in avoiding producing, make pesticide processing produce low poisoning, ensure people and animals' safety and health.The technological process of production is simple, and the investment of production equipment expense is low, is easy to processing.
2, butyl ether urea aqueous emulsion provided by the invention not only has crop and well adheres to and permeability, and properties of product are stable, and is higher to the insect activity, improved drug effect, reduces the dosage of medicament simultaneously.
3, butyl ether urea aqueous emulsion provided by the invention can be used as the desirable public nuisance-free agricultural chemicals insecticide of integrated pest control fully.
