Abstract
The invention discloses aqueous emulsion of lambda-cyhalothrin, which at least comprises components with weight percent of 1-10 percent of lambda-cyhalothrin, 1-15 percent of solvent, 1-20 percent of surfactant, 0.1-10 percent of stabilizer and the rest is water. Firstly, the lambda-cyhalothrin is dissolved in the solvent and then added with the surfactant which is then homo-dispersed so as to obtain a homogeneous mixed solution; the obtained homogeneous mixed solution is added with the stabilizer and water and then well stirred to obtain milk-white lambda-cyhalothrin aqueous emulsion. The lambda-cyhalothrin aqueous emulsion prepared by the invention does not contain aromatic organic solvent, which reduces the pollution to the environment effectively. The prepared lambda-cyhalothrin aqueous emulsion has the advantages of small grain diameter of droplet, homodisperse and high stability, etc., thus improving the dispersity of lambda-cyhalothrin and the compounded boosters thereof in the lambda-cyhalothrin aqueous emulsion so as to increase the using ratio of primary agent and auxiliary agents. The preparation method of lambda-cyhalothrin aqueous emulsion is simple and low energy consumption.
