Abstract

The invention discloses a synergisticanti-caking agent for a macroelement WSF (water-soluble fertilizer). Theanti-caking agent is prepared from raw materials in parts by weight as follows: 50-100 parts of a synergistic component and 0.5-2 parts of an anti-caking component, wherein the synergistic component is selected from one or a mixture of some of polyaspartic acid, polyglutamic acid, brassinolide, glycine betaine, N-acetyl-thioproline, folic acid, sodium naphthalene-1-acetate, 6-benzylaminoamidopurine and tetramethylglutaric acid; theanti-caking component consists of a silicon dioxide series product and a surfactant; the silicon dioxide series product is selected from one or a mixture of some of nanoscale silicon dioxide, gas-phase hydrophilicsilicon dioxide and gas-phase hydrophobicsilicon dioxide. The invention further discloses a preparation method of the synergisticanti-caking agent for the macroelement WSF. The anti-caking agent can prevent the macroelement WSF from caking, contains silicon required by promotion of crop growth and plays a role in increasing the fertilizer efficiency.

Description

technical field [0001] The invention relates to an anti-caking agent for a synergistic macroelement water-soluble fertilizer, which belongs to the technical field of fertilizers. Background technique [0002] Water Soluble Fertilizer (Water Soluble Fertilizer, WSF for short) is a multi-element compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water, more easily absorbed by crops, and its absorption and utilization rate is relatively high. [0003] At present, the outstanding problem in the production of solid water-soluble fertilizers is that the products are prone to moisture absorption and caking, especially in the process of processing, storage and transportation. Generally, products containing urea, potassium dihydrogen phosphate, magnesium sulfate (with crystal water), and chelated trace elements tend to absorb moisture and agglomerate. During the process of fertilizer processing, storage and transportation, due to the moistu...
