Concave convex rod suspension agent

Abstract

The invention discloses an concave-convex bar suspending agent, and the key points of its technical solution: uniformly blending sodium modified concave-convex bar clay, sodium silicate, sodium dodecyl sulfate and polyacrylamide, then inputting the uniform mixture into a grinding machine to grinding into powder with grain size <=0.044 mm, and finally packaging into finished products. And it has characters of simple producing process, low cost, high suspending ratio, good diffusing stability, and excellent performances in the aspects of anti-freezing function, rheological property, film forming characteristic and adhesive property. And it is applied to make various pesticide suspending agents.

Description

Technical field: [0001] The invention relates to a suspending agent, in particular to an attapulgite suspending agent. Background technique: [0002] Suspension concentrate is a new dosage form with a relatively short history of development in pesticide preparations and is constantly being improved. The emergence of this new dosage form provides a new opportunity for the production and application of solid pesticide formulations that are difficult to dissolve in water and organic solvents. , the existing pesticide suspensions are mainly chemical products, including: imidacloprid, mancozeb, thiram, diuron, rituron, chlorothalonil, tebufenozide, weed-killing, carbendazim, basic sulfuric acid Copper and Carbofuran etc. Surfactants, dispersants, stability and other auxiliary agents need to be added to these pesticide suspensions. The Chinese patent authorization announcement number CN 1088977, the date of publication is August 14, 2002, and the name is: "Benzothiazole herbicide...

AI Technical Summary

Problems solved by technology

[0003] A good suspending agent needs to show good performance in terms of dispersion stability, anti-agglomeration function, rheological properties, film-forming property and cohesiveness, etc. Some suspending agents are easy to stratify, aggregate and agglomerate during storage , affecting the promotion of the application

[0004] According to investigations, the attapulgite or bentonite currently available on the market is only ground into raw ores and then packaged as finished products for sale to pesticide factories. There are also reports that activated attapulgite or bentonite are used as stabilizers and fillers in pesticide suspensions , after testing, the viscosity of activated attapulgite or bentonite is very low, or even has no viscosity, which will accelerate the precipitation of the suspending agent in the pesticide suspending agent and reduce its suspension rate, and the quality of the pesticide suspending agent cannot be guaranteed at all.
