Embodiment 1
[0027] Embodiment 1: compound fertilizer anti-caking agent 1
[0028] A preparation method of compound fertilizer anti-caking agent, it comprises steps:
[0029] (1) Taking raw materials according to the proportioning ratio for subsequent use;
[0030] (2) Mix the fatty acid and fatty alcohol at a mass ratio of 1:1 and react at 65°C for 2.5 hours to obtain reactant A for use;
[0031] (3) put C 12 -C 18 Alkyl alcohols and phosphorus pentoxide are reacted at 80°C for 6 hours at a ratio of 2.5:1 to obtain phosphoric acid ester for later use;
[0032] (4) 12 parts of reactant A, 8 parts of phosphoric acid ester, 10 parts of span-60, 2 parts of dodecylsulfonate, 15 parts of triethanolamine, 0.6 part of polyglutamic acid, 2- 2 parts of chloro-6-trichloromethylpyridine and 50.4 parts of coconut oil are evenly mixed, then heated and reacted at 70-80° C. to obtain the anti-caking agent for compound fertilizer.
