Low-foam efficient pesticide water suspending agent aid and preparation method thereof

Abstract

The invention discloses a low-foam efficient pesticide water suspending agent aid. The low-foam efficient pesticide water suspending agent aid contains the following raw materials in parts by mass: 3-4 parts of a dispersing agent A, 1-3 parts of a wetting agent B and 0.1-0.3 part of a synergist C, wherein the dispersing agent A contains the following components in parts by mass: 100-600 parts of 2-vinylpyridine, 900-1000 parts of deionized water, 100-900 parts of organic acid, 10-150 parts of a chain transfer agent, 10-150 parts of an initiator and 6-20 parts of alkali; and the wetting agent Bcontains the following components in parts by mass: 1-10 parts of an initiator, 150-250 parts of ethylene oxide, 150-250 parts of epoxypropane and 0.03-0.3 part of a bimetallic cyanide complex catalyst. By virtue of the compounding use of a polycarboxylate dispersing agent and a block polyether wetting agent, the deficiency that an ion type aid is easy to bubble in the preparation process of a pesticide water suspending agent is greatly improved, so that the situation that excessive foams are formed in the use process is avoided, the wasting is avoided, and unnecessary pollution is prevented.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to a low-foaming and high-efficiency pesticide water suspension additive and a preparation method thereof. Background technique [0002] Pesticide adjuvants refer to the general term for various auxiliary materials used in the processing and application of pesticide formulations. Although adjuvants themselves generally have no biological activity, they are indispensable additives in the formulation of formulations or during application. Each pesticide adjuvant has a specific function: some can dilute the original drug, some can help the original drug to disperse evenly in the preparation, some can increase the wettability, adhesion or permeability of the particles, some can Some can prevent the decomposition of active ingredients, some can increase the safety of pesticide application, and some can increase the control effect of chemical pesticides when used with chemic...

AI Technical Summary

Problems solved by technology

[0003] However, there are still some shortcomings in the pesticide adjuvants in the prior art, such as too much foam during use, which easily overflows the container, thereby causing unnecessary pollution to the environment while causing waste, and the production process is relatively complicated, which is not conducive to mastering product quality etc.
