Emulsion-in-water insecticide and production process of emulsion-in-water insecticide

Abstract

The invention relates to emulsion-in-water insecticide and a production process of the emulsion-in-water insecticide and in particular relates to green and environment-friendly emulsion-in-water insecticide. The emulsion-in-water insecticide is prepared from the following raw materials in parts by weight: 25 to 35 parts of tea saponin, 10 to 20 parts of hydrogen peroxide, 20 to 30 parts of baking soda, 0.01 to 0.03 part of isodecyl neopentanoate, 0.01 to 0.02 part of isopropyl palmitate, 40 to 55 parts of tetramethrin, 15 to 25 parts of butylbenisothiazolene, 20 to 25 parts of garlic, 10 to 30 parts of Chinese prickly ash liquid, 10 to 15 parts of a pesticide emulsifier 04#, 5 to 15 parts of a pesticide emulsifier 602# and 15 to 20 parts of fulvic acid. The emulsion-in-water insecticide has the advantages of wide applicable range, stable preparation, obvious synergism and simple production process.

Description

technical field [0001] The invention relates to the field of water-emulsion pesticides, in particular to a water-emulsion pesticide and a production process thereof. Background technique [0002] With the strengthening of people's awareness of the environment, it is required to reduce the environmental hazards caused by the use of pesticides. In order to meet this social requirement, in the development of pesticide products, while focusing on the development of new varieties of pesticides with low toxicity and high efficiency, higher requirements are put forward for pesticide preparations, and the development of pesticide preparations is required to be solidified and water-based. [0003] The international code name of water emulsion dosage form is Ew, which was once called concentrated emulsion (Concentrate Emulsion). It is a preparation that disperses the liquid pesticide original medicine prepared by mixing liquid or solvent with small droplets of 0.5-1.5 microns in water...

AI Technical Summary

Problems solved by technology

[0004] (1) Short storage stability time: the normal storage time of pesticides is 2-3 years, while the normal storage time of water emulsion is about 1 year; Physical and chemical changes, ultraviolet light, time, water quality and other reasons cause demulsification, that is, the separation of water and solvents to form layers; (3) Precipitation is prone to occur: due to the decomposition of additives and original drugs, the original The medicine is pumped out from the preparation, forming a rice grain or crystal-like substance and sinking to the bottom, which greatly reduces the efficacy of the product and the content of active ingredients; (4) It is difficult to solve the problem of pesticide synergy: because it is mainly water The formation of solvent and emulsion in water is a principle of dynamic stability. Conventional synergists such as doublycides, vegetable oils, silicones, thione, etc., are extremely unstable in this dosage form. Therefore, the normal dosage form surface of emulsion in water The swelling force is similar to the surface swelling force of water, and the poor adhesion and penetration are the biggest problems of the water emulsion, which is difficult to improve the efficacy of the product
