Embodiment 1

[0020] In the reaction kettle, add 1000kg of water, heat to 60-70°C, add 100kg of Gemini quaternary ammonium salt with medium degree of polymerization, 200kg of nonionic SAA, 600kg of anionic SAA, and 100kg of polymer in sequence under stirring. After fully stirring, use a small amount of hydrochloric acid (HCL) solution or caustic soda (NaOH) solution to adjust the pH to 6.5-7.5. Then discharge and pack under stirring. This formula is mainly used for crystal anti-caking of inorganic salt potassium ore.

Embodiment 2

[0022] In the reaction kettle, add 1000kg of water, heat to 65°C to 75°C, add 550kg of anionic SAA, 120kg of polymer, 100kg of Gemini quaternary ammonium salt with high degree of polymerization, and 230kg of nonionic SAA successively under stirring. After fully stirring, use a small amount of caustic soda (NaOH) solution or hydrochloric acid solution to adjust the pH to 6.5-7.5. Then discharge and pack under stirring. This formula is mainly used for anti-caking of granular compound fertilizer.

Abstract

The invention discloses an anticaking agent containing surfactant and the preparation method, belongs to the chemical field, that is, addictive of inorganic salt / chemical fertilizer. The main function of the invention is to prevent inorganic salt / crystal of chemical fertilizer / particles from caking. The invention includes the anti-caking agent and the preparation method. The anti-caking agent of the invention contains hyper-branched ghimici quaternary ammonium salt, anionic surfactant, nonionic surfactant and polymer, wherein, quaternary ammonium accounts for 2-10%; anionic SAA accounts for 5-15%; nonionic SAA accounts for 40-70%; polymer accounts for 2-15; the rest is water. The method for preparing the anti-caking agent is also included.

Description

technical field [0001] The invention is an anti-caking agent containing surfactant and a manufacturing method thereof. Belonging to the field of chemistry, it is an additive for inorganic salts and chemical fertilizers. Background technique [0002] In the inorganic salt and chemical fertilizer industries, anti-caking technology has been applied. In the past this type of technology, due to the incompatibility of the existing production process due to the complexity of the process method in industrialized and large-scale production, or the interference of additives on product quality and the increase in cost, and the impact on the staff during use Physical health and environmental impacts have always been a problem for the industry not to use it correctly and normally. However, the anti-caking agent technology of the present invention uses hyperbranched quaternary ammonium salts for the first time, which is called "new surfactant in the 21st century", and practically and cr...
