Abstract

The invention discloses an anti-caking agent for fertilizer, the components of which comprise (mass percentage): 5 percent to 20 percent of dodecafluoro-heptanol sulfosuccinate, 9 percent to 30 percent of primary amine salt or secondary amine salt with the carbon atom number of 6 to 40, 10 percent to 50 percent of phospholipid oil, 10 percent to 40 percent of fatty acid ester, 5 percent to 30 percent of fatty acid, and 1 percent to 20 percent of paraffin, and the sum of each component is 100 percent. When the anti-caking agent for fertilizer is mixed with the fertilizer, a film which has stronger moistureproof and waterproof capacity than the existing anti-caking agent for fertilizer can be formed on the surfaces of fertilizer particles, thereby being capable of effectively preventing theparticles of compound fertilizer from being adhered to a whole during the storage period, simultaneously preventing the invasion of environmental moisture, having very strong capacity for inhibiting the growth of fertilizer crystals, leading the fertilizer to keep loose for a long time during the storage period and greatly improving the effect so as to ensure the quality of the fertilizer. The invention also discloses a preparation method and applications of the anti-caking agent for fertilizer.

Description

technical field [0001] The invention relates to the technical field of fertilizer anti-caking treatment, in particular to a fertilizer anti-caking agent and its preparation method and application. Background technique [0002] At present, the anti-caking treatment of fertilizers is very common at home and abroad. For example, the anti-caking agents of ammonium bicarbonate include sodium p-toluenesulfonate, pentadecylsulfonyl chloride, ammonium dodecylbenzenesulfonate, etc., and also use alkylbenzenesulfonic acid or its salts together with stearic acid and kerosene , water and so on. Some fertilizer anti-caking agents are composed of fatty amines, amine salts of phosphate esters or amine salts of alkylaryl sulfonic acids and a reactant of alcohol or amine with hydrophilic properties and carboxylic acid or anhydride. It is also compounded with a compound of primary or secondary amine and fatty acid salt containing 14 to 22 carbon atoms and wax or mineral oil. Fatty amines, ...
