Problems solved by technology

[0003] Existing oil antistatic agents are mainly composed of polyamines, polysulfones and solvents. However, during the use of this type of oil antistatic agents, the electrical conductivity of oils will attenuate and decrease, and long-term addition to oils It will make the performance of the oil unstable, and affect the performance indicators of the oil such as vapor pressure, distillation range, and copper corrosion.

Abstract

The invention discloses an antistatic agent for oil products, which comprises the following raw materials in parts by weight: 30-48 parts of active components, 10-26 parts of synergists, and 6-50 parts of cosolvents, wherein the active components are alkanes Any one of polysulfone and alkylpolyamine, or a mixture of polysulfone and polyamine; the synergist is any one or several of C3-30 acids; the C3 The ‑30 acid is an alkyl acid with 3‑30 carbon atoms or an organic acid containing an unsaturated double bond; meanwhile, the present invention also provides a preparation method and application of the oil antistatic agent. The antistatic agent for oil provided by the invention is green and environmentally friendly; after adding 1-5mg / L to the oil, the electrical conductivity of the oil can be increased to more than 300 pS / m, and it can be placed under normal temperature and pressure for 3 months , the electrical conductivity of the oil does not decrease significantly; the antistatic agent has good mutual solubility and dispersibility with the oil, and the oil has good stability after being added.

Description

technical field [0001] The invention belongs to the technical field of antistatic additives, and in particular relates to an oil antistatic agent and its preparation method and application. Background technique [0002] According to the requirements of GB 6950-2001 "Safe Static Conductivity of Light Oil Products", the safe static conductivity value of jet fuel should be 50-600 pS / m, and the safe static conductivity value of gasoline, kerosene and diesel should be greater than 50 pS / m, However, with the refined processing of oil products, the conductive sulfur, nitrogen, acid, etc. are all removed, and the weak conductivity that it should have is also eliminated. In order to ensure the safe transportation, storage and use of gasoline, diesel, kerosene and other hydrocarbon fuels and avoid explosion accidents, it is necessary not only to strengthen protective measures and standardize operations in strict accordance with the "General Guidelines for the Prevention of Electrostat...
