[0018] A preparation method based on the antistatic agent of polyhydroxy waste oil quaternary ammonium salt, comprising the following steps:
[0019] Step 1: Heat 50 parts by mass of waste oil to 60°C, filter while it is hot, remove the insoluble matter therein, add the filtrate to the first reaction vessel, add 50 parts by mass of sulfuric acid solution with a mass concentration of 8%, and set the temperature at 90 Stir the reaction at ℃ for 10 h. After the reaction system drops to room temperature, let it stand for liquid separation, and wash the oil phase three times with an equal volume of water to obtain product A;
[0020] Step 2: Add 14 parts by mass of product A to the second reaction container, then add 10 parts by mass of epichlorohydrin, stir and react at room temperature for 36 hours, after the reaction is over, remove excess epichlorohydrin, Then placed in a vacuum oven at 80°C and dried for 6 hours to obtain product B;
[0021] Step 3: Add 9 parts by mass of pro...
Embodiment 2
[0023] A preparation method based on the antistatic agent of polyhydroxy waste oil quaternary ammonium salt, comprising the following steps:
[0024] Step 1: Heat 50 parts by mass of waste oil to 60°C, filter it while it is hot, remove the insoluble matter, add the filtrate to the first reaction vessel, add 50 parts by mass of sulfuric acid solution with a mass concentration of 8%, and heat it at 90°C Under the condition of stirring and reacting for 10 hours, after the reaction system was lowered to room temperature, the liquid was separated, and the oil phase was washed three times with an equal volume of water to obtain the product A;
[0025] Step 2: Add 14 parts by mass of product A to the second reaction container, then add 30 parts by mass of epichlorohydrin, and stir and react at room temperature for 12 hours. After the reaction, remove excess epichlorohydrin, Then placed in a vacuum oven at 80°C and dried for 10 hours to obtain product B;
