Abstract

The invention discloses a nano compound pour point depressant and a preparation method thereof. The nano compound pour point depressant disclosed by the invention is compounded from a nano material and a polymer pour point depressant by a melting and blending method. A montmorillonite nano material modified by cetyl trimethylammonium bromide is compounded with the polymer pour point depressant in a certain mass ratio by adopting the melting and blending method so as to obtain the nano compound pour point depressant. The pour point depression effect of the nano compound pour point depressant is further enhanced on the basis of pour point depression of the original pour point depressant. When the nano compound pour point depressant is applied to 0# diesel oil, the pour point depression effect is superior to that of a commercially available pour point depressant, and the cold filter plugging point and the condensation point are respectively reduced by 12-20 DEG C and 18-26 DEG C.

Description

technical field [0001] The invention specifically relates to a nanocomposite pour point depressant and a preparation method thereof, belonging to the technical field of biomass energy additives. Background technique [0002] With the continuous development of the world economy, human beings have an increasing demand for energy, and petrochemical diesel has become the energy that people rely on for survival. However, in the winter in northern my country and some cold regions, since diesel oil is a mixture containing multi-component complex hydrocarbons, wax crystals will be precipitated when the temperature drops. structure, blocking the engine oil pipeline and filter, so that the engine cannot work normally. [0003] In recent years, with the development of nanotechnology, polymer / inorganic nanocomposites and inorganic nanohybrid materials have become the research hotspots of scholars at home and abroad. By introducing inorganic nanoparticles into polymer materials, its per...
