Carbendazim wettable powder and preparation process thereof

Abstract

The invention discloses carbendazim wettable powder. The carbendazim wettable powder is prepared by the following raw materials, by mass percent: 36%-42% of carbendazim, 0.5%-1.8% of a wetting agent,7.2%-7.8% of a dispersant, and 12%-32% of a filling material. The beneficial effects of the carbendazim wettable powder and the preparation process thereof are that when the dispersant contained in the wettable powder is prepared, phenol or derivatives of phenol are added and a phenolic hydroxyl group is introduced, which improves the reaction activity of lignin in pulping black liquor and the temperature resistance of the product, ensures that the raw materials are reacted and mixed more comprehensively when the wettable powder is prepared and improves the antifungal performance of the wettable powder. An ultrafine grinding mechanism used in the preparation process of the invention crushes and pulverizes the raw materials by rotating a rotary grinding wheel between a rotary grinding discI and a rotary grinding disc II in opposite directions. Moreover, multiple arc-shaped scraping knives arranged on the rotary grinding wheels with equal radians scrap the raw materials into a grindinggroove for extrusion and crushing so as to crush the raw materials more comprehensively, thoroughly and finely, which improves the quality of the crushing of the raw materials.

Description

technical field [0001] The invention relates to a wettable powder, specifically a carbendazim wettable powder and a preparation process thereof, belonging to the technical field of wettable powder applications. Background technique [0002] With the rapid development of science and technology, carbendazim wettable powder is used more and more frequently in the agricultural field. Carbendazim wettable powder is a systemic fungicide, which is effective against certain pathogenic bacteria of Ascomycetes and half-known fungi. Most pathogenic fungi are effective. The mechanism of action is to interfere with the mitotic process of cells. Carbendazim wettable powder is mainly used to control crop diseases caused by fungi. [0003] The existing carbendazim wettable powder and its preparation process still have many deficiencies. When the existing carbendazim wettable powder is prepared, the efficiency and quality of the dispersion, mixing and reaction of each raw material are poor...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of the poor efficiency and quality of dispersion, mixing and reaction of various raw materials during the preparation of the existing carbendazim wettable powder, resulting in poor fungicidal performance when the carbendazim wettable powder is used, and During the preparation of the existing carbendazim wettable powder, the raw materials of each component are pulverized incompletely and finely, resulting in poor quality of the prepared carbendazim wettable powder, and the existing carbendazim wettable powder preparation process is in The problem of poor environmental protection during implementation, and a kind of carbendazim wettable powder and its preparation process are proposed
