Problems solved by technology

However, chemical fertilizers are easy to agglomerate in the process of production and use, which seriously affects the quality of products and the effect of use. The current solution is mainly to solve the problem of chemical fertilizer agglomeration through anti-caking agents
Existing anti-caking agents mainly include oil type and powder type; powder type anti-caking agents need to be sprayed with oily substances at the same time to adhere to the powder during use. Although this method has anti-caking effect, its use cost is high. And it is not easy to coat the surface of the water-soluble powder during use, and it is easy to make the water-soluble powder into agglomerates. Secondly, when the wrapped water-soluble powder is put into water, it is easy to form an oil layer and a powder layer on the water surface, causing water pollution; The caking agent is to dissolve the surfactant in water and spray it on the surface of the fertilizer to reduce the surface tension of the fertilizer, but this method brings in moisture, which is the direct cause of the caking of the fertilizer

Abstract

The invention discloses an environment-friendly water-soluble anti-caking agent, and a preparation method and application thereof. The environment-friendly water-soluble anti-caking agent is prepared from the following components in percentage by weight: 10 to 15 percent of aluminum potassium sulfate, 10 to 15 percent of aluminum ammonium sulfate and 70 to 80 percent of lauryl sodium sulfate, wherein the weight percentage sum of the components is 100 percent. The anti-caking agent provided by the invention is fully water-soluble powder; after the anti-caking agent and a water-soluble chemical fertilizer are mixed, the water-soluble chemical fertilizer is insusceptible to caking, and the water-soluble chemical fertilizer is directly dissolved into water, does not float on water in the chemical fertilizer applying process, is convenient to spray and avoids pollution to the water and the environment. The invention also provides the preparation method and the application of the environment-friendly water-soluble anti-caking agent.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizer production, and in particular relates to an environment-friendly water-soluble anti-caking agent and its preparation method and application. Background technique [0002] Chemical fertilizer is the abbreviation of chemical fertilizer, which is a fertilizer made by chemical method that contains one or several nutrients needed for the growth of crops. However, chemical fertilizers are easy to agglomerate in the process of production and use, which seriously affects the quality of the product and the effect of use. The current solution is mainly to solve the problem of chemical fertilizer agglomeration through anti-caking agents. Existing anti-caking agents mainly include oil type and powder type; powder type anti-caking agents need to be sprayed with oily substances at the same time to adhere to the powder during use. Although this method has anti-caking effect, its use cost is high. An...
