Microemulsion preparation taking rosin-based vegetable oil as solvent and preparation method thereof

Abstract

The invention provides a microemulsion preparation taking rosin-based vegetable oil as a solvent and a preparation method thereof, and relates to a pesticide preparation. The microemulsion preparation consists of the following raw materials in percentage by mass: 0.5 to 30 percent of pesticide active ingredients, 55 to 20 percent of emulsifier, 0 to 8 percent of cosolvent, 0.1 to 0.3 percent of defoamer, 1 to 30 percent of rosin-based vegetable oil, and the balance of water. The preparation method comprises the following steps of: adding the pesticide active ingredients, the rosin-based vegetable oil, the cosolvent, emulsifier and the defoamer into a reaction kettle, performing cutting and uniform dispersion at 2,000 to 5,000 rpm / min, and adding the balance of water into the mixture for high-speed cutting to obtain the microemulsion preparation taking the rosin-based vegetable oil as the solvent.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a microemulsion preparation using pine resin-based vegetable oil as a solvent and a preparation method thereof. Background technique [0002] For a long time, the production of domestic pesticide liquid preparations has widely used aromatic hydrocarbons (including benzene, toluene, xylene, etc.) organic solvents, polar solvents (such as methanol, N,N-dimethylformamide (DMF), cyclohexanone, etc.) etc., the annual consumption of "triphenyl" is as high as 200,000 to 300,000 tons, but these solvents have disadvantages such as low flash point, flammability and explosion, and high toxicity to humans and the environment. Organic solvents and additives will all enter the environment during the use of pesticides, polluting the environment and harming human health. [0003] In 1992, the U.S. government promulgated regulations prohibiting organic solvents such as toluene and xylene in pesticide p...

AI Technical Summary

Problems solved by technology

[0005] Compared with emulsifiable concentrates, microemulsions replace most of the organic solvents with water, and the safety performance has been greatly improved, but it still needs to use a certain amount of aromatic hydrocarbons and other non-environmentally friendly organic solvents or polar solvents to dissolve and disperse the active ingredients of pesticides, and The emulsifiers used are usually not biodegradable, so there are certain unsafe hazards to the environment and people, which need to be improved
