Environment-friendly anti-blocking agent for compound fertilizer and preparation method of environment-friendly anti-blocking agent

Abstract

The invention discloses an environment-friendly anti-blocking agent for a compound fertilizer. The environment-friendly anti-blocking agent for the compound fertilizer is prepared from the following raw materials in parts by weight: 32-35 parts of white oil solid paraffin, 15-20 parts of nanoscale silicon dioxide, 3-5 parts of aliphatic polyurethane resin, 3-5 parts of EM bacteria, 2-4 parts of a surfactant, 16-18 parts of natural vegetable oil, 4-6 parts of vinyl acetate, 7-9 parts of benzoyl peroxide, 3-5 parts of iso-tridecanol, 7-9 parts of N,N-dimethyl stearyl amine and 1-3 parts of a film-forming agent. The agent overcomes the defects in the prior art, is reasonable in design, low in use cost, high in anti-caking performance, natural, environmentally friendly, and convenient to absorb by crops, and has high social use value and application prospects.

Description

technical field [0001] The invention relates to the technical field of anti-caking agents, in particular to an environment-friendly anti-caking agent for compound fertilizers and a preparation method thereof. Background technique [0002] Compound fertilizer products all have a certain degree of hygroscopicity, but there are differences in severity between different varieties. Due to changes in external conditions such as humidity, temperature, and extrusion during production, packaging, and storage, some loose powdery, granular, and spherical solids will lose their fluidity and form hard and difficult-to-break lumps. The agglomeration of the compound fertilizer destroys its free flow state, which not only brings great inconvenience to the application, but also affects the fertilizer efficiency of the product, and even fails in severe cases, increasing the application cost and application amount, causing economic losses for the user, and also It will have a negative impact ...

AI Technical Summary

Problems solved by technology

[0007] This kind of anti-caking agent compounded by engine oil, wax substances and surfactants is absorbed by the fertilizer particles after the engine oil overflows. The engine oil has serious harm to the germination and root system of crops. It will die, and there will be traces of oil on the water surface after fertilization in paddy fields. Not only the rice seedlings will be damaged, but also the water quality and the environment will be polluted. Long-term use will pollute the environment especially seriously.
