Embodiment 1

[0099] Weigh 0.44g of the pretreated aliphatic amine cationic surfactant, add 0.02g of concentrated hydrochloric acid as an acidifying agent, stir well, then add 0.34g of rice bran wax, heat, raise the temperature to 100°C, stir for 10min, to a uniform solution. Then add 12g of stearic acid and 7.2g of animal and vegetable oils, heat up to 80°C, stir for 15min, and obtain a homogeneous solution. After cooling, the sample is obtained. Embodiment 1 is tested according to the above laboratory sample performance test method, and compound fertilizer is potassium sulfate type (N: P 2 o 5 :K 2 0=15:15:15). The anti-caking performance test result of Example 1 shows that the looseness after 7 days is 96%.

Embodiment 2

[0101] Weigh 5.56g of the pretreated aliphatic amine cationic surfactant, add 0.27g of concentrated hydrochloric acid acidifier, stir evenly, then add 4.17g of rice bran wax, heat, raise the temperature to 100°C, stir for 10min, to a uniform solution. Then add 10 g of stearic acid and 8 g of animal and vegetable oils, heat up to 80° C., stir for 15 min, and obtain a uniform solution. After cooling, the sample is obtained. Embodiment 2 is tested according to the above laboratory sample performance test method, and compound fertilizer is potassium sulfate type (N: P 2 o 5 :K 2 0=15:15:15). The anti-caking performance test result of Example 2 shows that the looseness after 7 days is 97%.

Embodiment 3

[0103] Weigh 0.56kg of the pretreated aliphatic amine cationic surfactant, add 0.02kg of concentrated hydrochloric acid acidifier, stir evenly, then add 0.42kg of rice bran wax, heat, raise the temperature to 100°C, stir for 10min, to a uniform solution. Then add 18kg of stearic acid and 11kg of animal and vegetable oils, heat up to 80°C, stir for 15min, and obtain a homogeneous solution. After cooling, the sample is obtained. Embodiment 3 is tested according to the above field performance test method, and the compound fertilizer is a high nitrogen fertilizer (N:P 2 o 5 :K 2 O=28:6:6), the stacking time is 20 days. The anti-caking performance test result of Example 3 shows that the looseness after 20 days is 100%.

Abstract

The invention relates to a full-biodegradable oil-soluble anti-caking agent for a compound fertilizer and a preparation method and application thereof. The anti-caking agent consists of the following raw materials: a surfactant, an acidifier, vegetable wax, waste oil and fatty acid mixture and more preferentially also comprises a nonionic surfactant and/or sodium ferrocyanide. In the invention, the prepared anti-caking agent can be completely bio-degraded in natural environment, the preparation technology is relatively simple, the cost performance is relatively high, the caking of a chemical compound fertilizer caused by dampness and extrusion can be effectively prevented, and the anti-caking rate of the most easy-to-cake potassium sulfate compound fertilizer and high-nitrogen compound fertilizer is greater than 96%, preferentially greater than 98% and more preferentially greater than 99% and approaches and even reaches 100%.

Description

technical field [0001] The invention belongs to the field of anti-caking agents for compound fertilizers and the field of high-value chemical utilization of surfactants (especially fatty amine cationic surfactants) and waste oils (especially animal and vegetable oils). It specifically relates to a fully biodegradable oil-soluble anti-caking agent used in compound fertilizers, a preparation method and application thereof. Background technique [0002] With the continuous improvement of people's understanding of scientific fertilization, compound fertilizers are used more and more due to the reasonable ratio of N, P, and K nutrients; however, compound fertilizers have brought many difficulties to fertilizer users due to the problem of agglomeration . The agglomerated fertilizer must be re-crushed and re-screened, which inevitably increases additional costs, and also results in loss of fertilizer and generation of dust, which will definitely bring harm to the health of the ope...
