Abstract

The invention discloses a preparation method of attapulgite high-performance pesticide carrier. The preparation method comprises the following steps: purifying attapulgite clay, drying, grinding, adding an additive, baking at a low temperature, cooling, grinding again, then adding another additive to mix evenly and prepare the pesticide carrier. The modified attapulgite obtained through a series of treatments has the original characteristics of attapulgite that the attapulgite has high absorbability and is inert to pesticide; the surface acid value of the original attapulgite can be reduced, the specific area can be increased, the water absorption rate can be reduced; the modified attapulgite can be used as pesticide carrier to replace white carbon black, thus the drug concentration can be reduced, the medical effect can be prolonged and the environmental pollutions caused by pesticide can be reduced. Therefore, the modified attapulgite has great significance in increasing the qualityof the Chinese powder pesticide, reducing the dosage of the Chinese pesticide and expanding the exports of the Chinese pesticide and carrier.

Description

technical field

[0001] The invention relates to a preparation method and application of modified attapulgite clay. Background technique

[0002] my country is a large agricultural country, and a large amount of pesticides are needed every year to ensure high agricultural yields. With the use of a large amount of pesticides, environmental pollution and environmental deterioration will inevitably occur. Therefore, it is imminent to reduce the amount of pesticides used and improve the level of pesticide formulations. Pesticide powders and granules have many advantages - less organic solvents are used, high utilization of pesticide active components, and the carrier itself for powders has no pollution to the environment. Therefore, the development of specific surface area, strong adsorption, and low surface acid value ( That is, the high-performance pesticide carrier with a large pKa value has a very broad market prospect.

[0003] The quality and performance of powder pesticid...
