Problems solved by technology

However, the anti-caking effect of most fertilizer anti-caking agents has failed to meet the higher requirements of users on the quality of fertilizers, including looseness. It is difficult to really solve the problem of caking of compound fertilizers during long-term storage. will inevitably be affected

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 the particles 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, ...
