Example Embodiment

[0014] The preparation method of the oil antistatic agent of the present invention is specifically implemented according to the following steps:

[0015] step 1,

[0016] According to parts by weight, weigh 50-60 parts of alkyl phosphate ammonium salt, 20-30 parts of fatty alcohol polypropylene ether, 14-20 parts of amino fluorocarbon polymer, 8-15 parts The cocoamide imidazoline.

[0017] Step 2.

[0018] Add the alkyl phosphate ammonium salt and fatty alcohol polypropylene ether obtained in the previous step to the reactor and vacuum, the vacuum pressure is 0.3MPa, and the vacuum time is to pump the alkyl phosphate ammonium salt and fatty alcohol polypropylene ether. When finished, within 60 to 90 minutes, raise the temperature of the reactor to 80°C to 90°C, start stirring for 60 to 90 minutes; then add the amino fluorocarbon polymer obtained in the previous step, and stir for 60 minutes; add The cocamidoimidazoline obtained in the previous step is stirred and reacted for 60 to 9...

Example Embodiment

[0026] Example 1

[0027] According to parts by weight, weigh 50 parts of alkyl phosphate ammonium salt, 20 parts of fatty alcohol polypropylene ether, 14 parts of amino fluorocarbon polymer, and 8 parts of cocamidoimidazoline. Add alkyl phosphate ammonium salt and fatty alcohol polypropylene ether to the reactor to vacuum, the vacuum pressure is 0.3MPa, and the vacuum time is until the alkyl phosphate ammonium salt and fatty alcohol polypropylene ether are exhausted. The reactor was heated to 80°C within 60 minutes, and the stirring reaction was started for 60 minutes; then the amino fluorocarbon polymer was added and the reaction was stirred for 60 minutes; the cocamidoimidazoline was added, and the reaction was stirred for 60 minutes, and then cooled to It is prepared at 35°C.

Example Embodiment

[0028] Example 2

[0029] According to parts by weight, weigh 60 parts of alkyl phosphate ammonium salt, 30 parts of fatty alcohol polypropylene ether, 20 parts of amino fluorocarbon polymer, and 15 parts of cocamidoimidazoline. Add alkyl phosphate ammonium salt and fatty alcohol polypropylene ether to the reactor to vacuum, the vacuum pressure is 0.3MPa, and the vacuum time is until the alkyl phosphate ammonium salt and fatty alcohol polypropylene ether are exhausted. The reactor was heated to 90°C within 90 minutes, and the stirring reaction was started for 90 minutes; then the amino fluorocarbon polymer was added and the reaction was stirred for 60 minutes; the cocamido imidazoline was added, and the reaction was stirred for 90 minutes, and then cooled to It is prepared at 40°C.

Abstract

The invention discloses an oil antistatic agent which is prepared by the following components by weight portions: 50-60 portions of ammonium alkyl phosphate salt, 20-30 portions of fatty alcohol polypropylene ether, 14-20 portions of amino fluorocarbon polymer and 8-15 portions of cocamide imidazoline. The ammonium alkyl phosphate salt and the fatty alcohol polypropylene ether are added into a reaction kettle for vacuum-pumping, the vacuum pressure thereof is 0.3MPa; the temperature of the reaction kettle is heated up to 80-90 DEG C within 60-90 minutes, then stirring reaction is started and lasts for 60-90 minutes; the amino fluorocarbon polymer is added for stirring reaction for 60 minutes; then the cocamide imidazoline is added for stirring reaction for 60-90 minutes; and the oil antistatic agent is obtained after cooling is carried out by a cooler to 35-40 DEG C. The oil antistatic agent has no toxicity, no special odor, good intersolubility and lubricating property, little addingamount, good stability and no foaming, and can effectively improve the electrical conductivity of fuel, and lead the antistatic performance of the fuel to achieve a higher safety index.

Description

Technical field [0001] The invention belongs to the field of antistatic technology, and relates to an oil antistatic agent used for fuel oil, and the invention also relates to a preparation method of the oil antistatic agent. Background technique [0002] The deep-processed fuel oil undergoes the hydrogenation unit process to remove the sulfur, nitrogen, colloid and other substances in the fuel oil, so that the sulfur content index is below 50ppm. However, in the fuel hydroprocessing production process, the oil is also removed The natural electrical conductivity of the oil reduces its electrical conductivity. The oil with low electrical conductivity will accumulate static electricity when it flows quickly (such as mixing, pumping, filtering oil), which is very prone to fire and explosion accidents. In order to ensure the safety of fuel use, scientific and technical personnel are constantly experimenting and researching high-tech oil antistatic products. The oil antistatic agent ...
