Abstract

The invention provides an oil performance improver. The oil performance improver comprises, by mass, 40-60% of benzyl methacrylate-tetradecyl methacrylate and 25-70% of a solvent; and the solvent is composed of 20-40% of dimethyl phthalate and 5-20% of cyclohexane, or the solvent is composed of 10-30% of n-butyl acetate, 5-20% of polyethylene glycol 200 and 10-20% of propylene glycol block polyether. The above diesel pour point depressant composition of the invention can effectively enhance the solubility of a pour point depressant in diesel, reduce the cost of the pour point depressant and effectively improve the low-temperature flow performance of the diesel.

Description

technical field [0001] The invention relates to an oil performance improver, a preparation method and application thereof, and belongs to the technical field of oil performance improvement. Background technique [0002] At present, the supply of diesel in my country is seriously insufficient, especially the demand for low freezing point diesel is more urgent. Low-temperature fluidity is an important condition for the use of low-condensation-point diesel, which is related to the content of n-alkanes in diesel, and pour point depressant is one of the most effective methods to improve low-temperature fluidity of diesel. Diesel pour point depressant, also known as low-temperature flow modifier, is an additive used continuously when blending diesel, which can keep diesel fluidity at lower temperatures. The pour point depressant has the advantages of economy, convenience, greenness and effectiveness, so it has become the first choice to improve the low temperature fluidity of die...
