Problems solved by technology

These organic solvents are cheap and have a good dissolving effect on pesticides. They have been used as solvents for pesticides for a long time, but these solvents only play a role in dissolving pesticides, and cannot effectively improve or increase the efficacy of pesticides. In addition, in the general trend of green environmental protection Under the current situation, this kind of solvent that pollutes the environment and may cause harm to the personnel in the spraying operation has become increasingly unable to meet the needs of development.

Abstract

The invention relates to a composite assistant for an emulsifier. The composite assistant comprises, by weight, 13-15 parts of epoxidized soybean oil, 1-3 parts of ethanol, 1-2 parts of chiral pyrrolidine-2, 5-dione and 1-3 parts of a surfactant. The invention also relates to a preparation method of the composite assistant. The composite assistant can improve emulsification effects in pesticide mixing in a barrel and improve effects after pesticide spraying.

Description

technical field [0001] The invention relates to the technical field of pesticide solvents, in particular to a composite auxiliary agent for emulsifiers. Background technique [0002] Pesticide formulations mainly include emulsifiable oil, water-emulsion, microemulsion and soluble liquid. Emulsifiers have been favored by farmers for a long time due to their good dispersion effect during use, high effective drug concentration and simple preparation during use. A large amount of organic solvents such as toluene and xylene will be used. These organic solvents are cheap and have a good dissolving effect on pesticides. They have been used as solvents for pesticides for a long time, but these solvents only play a role in dissolving pesticides, and cannot effectively improve or increase the efficacy of pesticides. In addition, in the general trend of green environmental protection Under the current situation, this kind of solvent that pollutes the environment and may cause harm to ...
