Embodiment 1
[0028] A hydrophobic compound pore embolus emulsion, its composition and proportion are respectively: 10wt% of hardened oil, 15wt% of ammonia water, 0.1wt% of defoaming and antifoaming agent, 1wt% of emulsifier, and the balance is water; wherein, the The mass concentration of ammonia water is 15%.
[0029] The preparation method of the hydrophobic compound pore embolus emulsion provided in this example, the specific steps are as follows: put 60g of hardened oil in a three-necked flask and heat it to 90°C to dissolve it for 10 minutes. After dissolving, add a few drops of ammonia water and 443.4g of water, then quickly stir and disperse at 1100r / min at 90°C for 1h; then, add the remaining 90g of ammonia water, 6g of emulsifier and 0.6g of defoaming and antifoaming agent at 65°C and stir at a medium speed of 750r / min for 3h ; Finally, slow down to room temperature with 450r / min stirring to obtain a hydrophobic compound pore embolus emulsion.
Embodiment 2
[0031] A hydrophobic compound pore embolus emulsion, its composition and proportion are respectively: 11wt% of hardened oil, 18wt% of ammonia water, 0.15wt% of defoaming and antifoaming agent, 1.3wt% of emulsifier, and the balance is water; The stated ammonia mass concentration is 18%.
[0032] The preparation method of the hydrophobic compound pore embolus emulsion provided in this example, the specific steps are as follows: put 66g of hardened oil in a three-necked flask and heat it to dissolve at a temperature of 90°C. The heating time is 10min. After dissolving, add a few drops of ammonia water and 417.3g of water, then quickly stir and disperse at 1200r / min at 90°C for 1h; then, add the remaining 108g of ammonia water, 7.8g of emulsifier and 0.9g of defoaming and antifoaming agent and stir at 60°C at a medium speed of 900r / min for ammoniation 3h; finally, slowly stir at 300r / min and cool down to room temperature to obtain a hydrophobic compound pore embolus emulsion.
Embodiment 3
[0034] A hydrophobic compound pore embolus emulsion, its composition and proportion are respectively: 13wt% of hardened oil, 22wt% of ammonia water, 0.3wt% of defoaming and antifoaming agent, 1.7wt% of emulsifier, and the balance is water; The stated ammonia mass concentration is 22%.
[0035] The preparation method of the hydrophobic compound pore embolus emulsion provided in this example, the specific steps are as follows: put 78g of hardened oil in a three-necked flask and heat it to 90°C to dissolve it for 10 minutes. After dissolving, add a few drops of ammonia water and 378g of water, then stir and disperse rapidly at 90°C at 900r / min for 1h; then, add the remaining 132g of ammonia water, 10.2g of emulsifier and 1.8g of defoaming and antifoaming agent and stir at 65°C at a medium speed of 600r / min for 3h; Finally, stirring at a slow speed of 400 r / min and cooling down to room temperature to obtain a hydrophobic compound pore embolus emulsion.
