Description
Technical field
The present invention relates to the preventing blocking technology field of composite fertilizer, especially a kind of degradable compound fertilizer anticaking agent and its preparation method and application.
Background technology
The agglomeration problems of composite fertilizer is more and more subject to the attention of manufacturing enterprise, major part fertiliser production enterprise all to granulated fertilizer caking mechanism and reason grope and inquire into, and take different preventing block methods to alleviate the caking of fertilizer, to ensure the free-running property of granulated fertilizer.
Existing anti-hard caking agent has three kinds, the molten type of powder-type, aqueous solution type and oil: 1, powder-type anti-hard caking agent is the formation utilizing inert powder to intercept brilliant bridge between fertiliser granulates, but need spray into oily matter to adhere to inert powder when using simultaneously.Although the method has anti-caking effect, complex process, cost are higher, and fertilizer dust is increased.2, aqueous solution type anti-hard caking agent is then by surfactant dissolves in water, is sprayed at fertilizer surface, to reach the object reducing fertilizer surface tension force and the effect playing anti-caking.The shortcoming of the method has brought moisture into, and moisture is the immediate cause of fertilizer agglomeration.3, Oil solvent type anti-hard caking agent avoids the shortcoming of above-mentioned two kinds of methods, there is easy to use, effective advantage, but traditional method need add mineral oil (as machine oil) as solvent, and the large usage quantity of mineral oil, be generally 4 ~ 5 times of anti-hard caking agent, the consumption of composite fertilizer per ton mineral oil in fluid reaches 2 ~ 3kg, and these mineral oil enter soil with fertilizer and are difficult to degraded, cause pollution to a certain degree to soil and surrounding enviroment.
Summary of the invention
For solving the deficiency existed in above-mentioned technology, the invention provides a kind of process simple, use cost is low, anti-caking performance good, pure natural environment protection, be convenient to farm crop and absorb, strengthen fertilizer efficiency, the degradable compound fertilizer anticaking agent of one of soil protection and its preparation method and application.
For achieving the above object, the invention provides a kind of degradable compound fertilizer anticaking agent, its component comprises aliphatic amide or its salt, stearic acid, oleic acid, refining glycerine, recycled wood materials, and above-mentioned each component sum is 100%, wherein, each component is by following per-cent proportioning:
Aliphatic amide or its salt: 5 ~ 15%,
