Abstract

The invention relates to sodium abietate micro-emulsion which is prepared from the following components in percentage by weight: 5-20% of sodium abietate, 2-20% of a surfactant, 2-10% of a solvent, 2-10% of a cosolvent, 0.1-5% of an antifoaming agent, 0.1-5% of an anti-freezing agent and the balance of water, totaling 100%.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a sodium rosinate microemulsion and a preparation method of the microemulsion. Background technique [0002] Sodium rosinate emulsion is a new type of insecticide based on natural raw materials, which has good fat solubility, film-forming properties and emulsifying properties. The current main dosage forms include emulsifiable concentrate, soluble powder, soluble granule, water dispersible granule and so on. [0003] CN103314957A discloses a sodium rosinate water-dispersible granule, which includes sodium rosinate soluble powder, desugared sodium lignosulfonate, sodium sulfate, filler or dispersant and adhesion promoter. [0004] CN1903042A discloses a method for preparing sodium rosinate soluble powder, which includes subjecting pine tree body to high-temperature and high-pressure treatment, separating gasoline from water, then purifying rosin, and finally undergoing saponification, ...
