Abstract

The invention provides a compound fertilizer anti-caking agent. The anti-caking agent is prepared from the following raw materials: fatty acid, fatty alcohol, span-60, dodecyl sulfonate, triethanolamine, phosphate, polyamino acid, nitrification prevention agent and vegetable oil, wherein the length of a carbon chain of the fatty acid and fatty alcohol is respectively 8 to 14. The preparation method of the anti-caking agent comprises the following steps: (1) measuring the raw materials for standby use according to a proportion; (2) mixing the fatty acid and the fatty alcohol, heating the mixture, reacting to obtain a reactant A for standby use; (3) preparing the phosphate; (4) uniformly mixing the reactant A, the phosphate, span-60, dodecyl sulfonate, triethanolamine, polyamino acid, the nitrification prevention agent and the vegetable oil, heating, reacting to obtain the anti-caking agent. The invention also provides compound fertilizer prepared from the anti-caking agent. The compoundfertilizer is obtained in the following steps of uniformly coating the compound fertilizer with the anti-caking agent in a smearing and coating way, wherein the addition amount of the anti-caking agent is 1 to 4 kg / t, and the particle size of the compound fertilizer is 1 to 4.75 mm. The anti-caking agent of the invention is lasting in effect, excellent in performance, environment-friendly, and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a compound fertilizer anti-caking agent, a preparation method thereof and a compound fertilizer prepared therefrom. technical background [0002] Compound fertilizer plays an increasingly important role in the fertilizer industry because it integrates multiple nutrients. However, compound fertilizer is more likely to agglomerate than single fertilizer during transportation and storage, which will cause its free flow to gradually disappear and make its quality For a long time, it has seriously affected the sales of enterprises and the use of users. Fertilizer agglomeration is a common problem in the chemical fertilizer industry. It will not only bring great difficulties to the storage, transportation and use of chemical fertilizers, but also seriously affect the fertilizer efficiency, reduce production efficiency, and cause economic losses to production enterprises.
