Problems solved by technology

The processing of pesticides for suspension concentrates generally requires its melting point to be ≥ 100°C. With the ever-expanding market demand for processing varieties of suspension concentrates, especially low melting point (melting point ≤ 70°C) raw materials for processing suspension more and more difficulties

Abstract

The invention relates to a dispersing agent suitable for a low-melting-point pesticide suspending agent. The dispersing agent is prepared from the following raw materials in parts by weight: 20-50 parts of phosphate wetting agents, 5-15 parts of polycarboxylate graft polymer and 20-50 parts of EO / PO (ethylene oxide / propylene oxide) block polyether emulsifiers. The dispersing agent can be widely suitable for processing solid raw pesticides with melting points lower than 70 DEG C, can not affect the environment and can effectively solve the problems plaguing the low-melting-point solid raw pesticide processing suspending agent for a long time in the aspect of a formula.

Description

technical field [0001] The invention relates to a dispersant suitable for low-melting pesticide suspension concentrates. Background technique [0002] At present, traditional pesticide suspension concentrates mainly include: pesticide technical, dispersant combination, thickener, antifreeze, defoamer and dispersion medium water. The use of water-based formulations to replace oil-based formulations that are flammable, toxic, and pollute the environment is becoming the development direction of pesticide formulations in the world. Suspension concentrate SC is a new dosage form that is developing rapidly and has great prospects in the world, and the prospect of developing suspension dosage forms in China is even more so. The processing of pesticides for suspension concentrates generally requires its melting point to be ≥ 100°C. With the ever-expanding market demand for processing varieties of suspension concentrates, especially low melting point (melting point ≤ 70°C) raw mater...
