Problems solved by technology

[0002] Most of the anti-caking agents currently on the market are amine flakes, paraffin and other high melting point substances dispersed in vegetable oil or mineral oil, and the paste formed has poor fluidity and needs to be heated to increase its fluidity during production and filling. , can be filled; in the process of use, it needs to be heated twice to dissolve, resulting in waste of resources and energy. What's more, in some manufacturers, it often occurs due to insufficient heating of the anti-caking agent or condensation of the anti-caking agent during transportation. Causes blockage of pipelines, brings great troubles to fertilizer production, causes frequent workshop parking accidents, and brings huge losses to fertilizer manufacturers

Embodiment 1

[0023] Liquid fertilizer anti-caking agent: silicone oil emulsion 60%, C 12 Sodium Alkylbenzene Sulfonate 20%, Triethanolamine 10%, C 9 Fatty alcohol polyoxyethylene ether AEO9 is 10%.

[0024] Preparation of silicone oil emulsion: (1) Preparation of silicone oil paste: Add 20% simethicone oil and 2% white carbon black to a reactor with a stirrer and temperature control to stir each component by mass percentage, and heat up to 100 degrees or more, not more than 160 degrees; treat for 4 hours, then cool to room temperature, and obtain white viscous liquid as modified silicon dioxide; (2) Preparation of silicone oil emulsion: keep the prepared silicone oil paste at 65 degrees, add 2% Tween 60 and 2% Span 80 emulsifiers, continue to stir for 30 minutes, then add 36% 65-degree warm water and stir for 30 minutes; take 1% hydroxymethylcellulose sodium powder and dissolve it in 9% 65-degree Make a 10% sodium hydroxymethyl cellulose aqueous solution in water, add all the sodium hydr...

Embodiment 2

[0027] Liquid fertilizer anti-caking agent: silicone oil emulsion 70%, C 12 Potassium alkylbenzenesulfonate 10%, triethanolamine 10%, AEO9 10%.

[0028] The preparation method of the liquid fertilizer anti-caking agent is the same as in Example 1.

Embodiment 3

[0030] Liquid fertilizer anti-caking agent: silicone oil emulsion 75%, C 18 Potassium alkylbenzenesulfonate 10%, triethanolamine 10%, AEO9 5%.

[0031] The preparation method of the liquid fertilizer anti-caking agent is the same as in Example 1.

[0032] The liquid fertilizer anti-caking agent prepared in Example 1 of the present invention is used in an amount of 1-3 kg / ton of fertilizer to effectively prevent the fertilizer from caking.

Abstract

The invention relates to an anti-caking agent for liquid fertilizer and a preparation method thereof. The anti-caking agent for liquid fertilizer comprises silicone oil emulsion, C12-C18 Alkyl Benzene Sulfonic Acid sodium salt or kali salt, triethavolamine, and C9 fatty alcohol polyoxyethylene ether AEO9. The preparation method comprises the following step: calculated according to mass percentage, all ingredients including 10% to 25% C12-C18 Alkyl Benzene Sulfonic Acid sodium salt or kali salt, 10% to 15% triethavolamine, and 5% to 10% fatty alcohol polyoxyethylene ether AEO9 are dispersed into 50% to 75% silicone oil emulsion, so as to obtain the anti-caking agent for liquid fertilizer. The invention has the advantages that the manufacturing technology is simple; the anti-caking agent can be directly sprayed on the surface of chemical fertilizer without heating in use process; the operation is simple; heating and extra special equipment are not needed; and the surface tension of free water can be effectively lowered with only 1 to 3 kilograms of anti-caking agent added into a ton of fertilizer to prevent the forming of crystal bridge among particles and effectively prevent fertilizer caking, so that the fertilizer can keep the loose state in long-time storage, and the effect is improved greatly to guarantee the quality of the fertilizer.
