Abstract
The invention relates to a high nitrogen compound fertilizer, in particular to an anticaking agent of the high nitrogen compound fertilizer and preparation and application thereof; the component of the anticaking agent includes olefin, alkylamine, S-80 and mineral oil; the weight ratios of the olefin, the alkylamine, the S-80 and the mineral oil are 18 to 25 : 3.7 to 10 : 3 to 4 : 75 to 61. A dewatering nonpolarity material and a cation surface active agent are adopted to be combined on the aspects of anti-moisture absorption and crystal bridge forming by the invention which not only utilizes the olefin to seal the surface of the fertilizer to prevent the water inside the fertilizer from leaking outside to cause the crystal bridge to be formed, but also restrains the adhesion of external vapor; the cation surface active agent is utilized on the aspect of controlling the moisture absorption of the fertilizer, which can improve the adhesive attraction of the anticaking agent, promote the extension of the anticaking agent on the surface of fertilizer particles when coating and improves the tractility for one aspect; for the other aspect, a dewatering base can prevent the external vapor from entering.
Description
Technical field
The present invention relates to high-nitrogen compound fertilizer, it is the technology that composite fertilizer that a kind of solution contains a large amount nitrogen prevents to cause because of moisture absorption caking, a kind of specifically high-nitrogen compound fertilizer anticaking agent and preparation and application are mainly used in anti-caking processing in the stronger composite fertilizer's production that contains a large amount nitrogen of water absorbability.
Background technology
Development along with fertilizer industry, corresponding supporting technology research is also constantly being goed deep into, wherein the kind that occurs along with the development of composite fertilizer is more and more, also drawn a series of problem, anti-moisture absorption difficulty, the serious problem of fertilizer agglomeration have appearred in the release of high-nitrogen compound fertilizer, especially melt after the body granulation process introduces at urea melting spray granulating and high tower, the fertilizer agglomeration of being produced increases the weight of, and present existing anti-hard caking agent can not address this problem fully.
At present, that produces the exploitation anti-hard caking agent in the world has the U.S. (Anticate17, Bar-Dust etc.), Britain, France (Graloryl, Steronia etc.), Germany (ISCO90), Holland (Portabor etc.), Spain (SK-Fert, Uresoft etc.) and Russia and a Sweden etc., and the anti-hard caking agent of being produced comprises cationic and types such as aniorfic surfactant, nonionogenic tenside, inert powder.In recent years the middle-size and small-size chemical enterprise of some of China is also being produced all kinds of anti-caking agent, and the anti-caking agent of using in the production of composite fertilizer divides two big classes in China, medium-sized and small enterprises are based on inert powder, and large and medium-sized enterprise uses the anti-hard caking agent of tensio-active agent one class more.Mainly there is several respects problem in the tensio-active agent that uses at present: the anti-hard caking agent that the present enterprise of the too high China of (1) imported product price uses mainly is the product that Spain spends the king, it also is the best product of effect, but price is too high, the ton valency has reached 14500-15500 unit/ton, than the high 30%-50% of home products, and spend king's product also to can't resolve the agglomeration problems of high nitrogen fertilizer (high tower melts the body granulation) at present; (2) the most of anti-hard caking agent of the not good home-made of effect is lower than the effect that 18% composite fertilizer can also reach moistureproof anti-caking for nitrogen content, but for the fertilizer of the particularly high tower prilling technology of high nitrogen, homemade currently available products fails to reach production requirement.
Summary of the invention
In order to solve high-nitrogen compound fertilizer, especially high tower melts the agglomeration problems of body granulation fertilizer, the invention provides a kind of high-nitrogen compound fertilizer anticaking agent and preparation thereof and application, the present invention is adopting hydrophobic non-polar material to combine with cats product aspect anti-moisture absorption and the brilliant bridge formation, promptly utilize paraffin sealing fertilizer surface, preventing that the fertilizer internal moisture from exosmosing causes brilliant bridge to form, also limit adhering to of external steam simultaneously, utilizing cats product aspect the moisture absorption of control fertilizer, it can improve the sticking power of anti-caking agent on the one hand, in the extension of granule surface, improve ductility when promoting the anti-hard caking agent coating; Hydrophobic group can prevent entering of external steam on the other hand.
To achieve these goals, the technical solution used in the present invention is:
A kind of high-nitrogen compound fertilizer anticaking agent, its composition comprises paraffin, alkylamine, S-80, mineral oil, the weight ratio of paraffin, alkylamine, S-80 and mineral oil is: 18-25: 3.7-10: 3-4: 75-61.
The weight ratio of described paraffin, alkylamine, S-80 and mineral oil is preferably: 21: 4: 3: 72.
Described paraffin is 7
#-58
#One of refining or semi-refined wax or its mix, and with the size of the number of selecting for use as required, choose low number paraffin when low temperature need improve ductility, select height paraffin in the time of improving hardness for use; Alkylamine is one of 13-18 kiber alkyl amine or its mixing; Emulsifying agent S-80 is a sorbitan mono-oleic acid ester; Mineral oil is 40
#-46
#One of machine oil or its mixing.
Its course of processing is: paraffin, alkylamine, S-80 and mineral oil are mixed in proportion, are heated to 70-80 ℃, stir reaction 20-30 minute, promptly form high-nitrogen compound fertilizer anticaking agent after the reaction.
During application: the anti-hard caking agent consumption is composite fertilizer 0.7-2.5kg/t per ton, can unite use with the inert powder material, adopts the vaporific spraying method of high pressure to be wrapped in the fertiliser granulates surface.
Rate of moisture absorption decline 18%-53% when high-nitrogen compound fertilizer anticaking agent of the present invention can be handled 7 days than colored king's product under open condition, caking rate decline 22.4-65.7% (60 days), because the application of extension agent S-80, the bag that has improved the anti-caking agent is coated with effect.
