Problems solved by technology

During the use of farmers, if they are not completely shaken, it is easy to cause phytotoxicity
Secondly, many dispersible oil suspension concentrates on the market are easy to precipitate solids or freeze completely at low temperatures, which brings great troubles to winter production or use in cold northern regions
Third, the active ingredients selected for the current dispersible oil suspension concentrates are usually compounds with higher melting points, which imposes great restrictions on the large number of low-melting point compounds today.
Fourth, the current production of dispersible oil suspensions needs to be ground by a sand mill. Due to the increase in the temperature of

Abstract

The invention discloses a dispersible oil suspension agent for a low-melting-point compound and a preparation method thereof. The dispersible oil suspension agent is characterized by being composed of following substances in percentage by mass: 5%-25% of the low-melting-point compound, 10%-20% of an emulsifying agent, 2%-5% of a dispersant, 2%-5% of a thixotropic agent and residual amount of a solvent, wherein the low-melting-point compound is a compound with the smelting point of 25-70 DEG C. The product disclosed by the invention has good stability; a layering and precipitation phenomenon does not occur; solids are not separated out or the product is not frozen at a low temperature and the mobility is good; meanwhile, the energy consumption is low, the production efficiency is high and the physicochemical properties of the product are stable, so that the dispersible oil suspension agent is possibly prepared from a lot of the low-melting-point compounds.

Description

technical field [0001] The invention relates to a low melting point compound dispersible oil suspension and a preparation method thereof. Background technique [0002] Dispersible oil suspension concentrate is a new type of pesticide formulation. Its outstanding feature is that the formulation is environmentally friendly. During use, it will not generate a lot of dust like wettable powder, and will not waste a lot of organic solvents like the production of emulsifiable concentrate. , it can also make those original drugs that are easy to decompose in water have a stable environment system. When the dispersible oil suspension concentrate is mixed with water and sprayed, it will increase the adhesion of the liquid medicine to the target, and has the effect of moisturizing, thus greatly increasing the effect of pest control. [0003] Due to the short development time of dispersible oil suspending agent in our country, there are still many difficult problems in the production p...
