Problems solved by technology

Due to the poor dissolving ability of n-alkanes to additives, the molecular groups of additives adsorb aluminum powder and grow up. When they adhere to high-speed rollers or bearings, they generate heat due to friction, and aluminum powder is flammable and explosive. Poor safety and stability of normal alkanes

Abstract

The invention relates to a method for preparing high-quality aluminum foil rolling base oil. In the method, the synthesis gas treated with impurities removed is passed through a Fischer-Tropsch synthesis section, a light removal tower, and a weight removal tower to obtain high-purity C10 ‑C15 n-paraffin and isoparaffin mixed distillate oil is used as raw material, which can be removed by porous metal organic framework material to obtain low-sulfur and low-aromatic aluminum foil rolling base oil with low viscosity, narrow fraction and high isomer content. The product prepared by the method of the invention has high isoparaffin content, concentrated carbon chains, narrow cuts, and repeated regeneration does not affect product quality. Low viscosity, fast spreading of oil film, uniform lubrication, good annealing cleanliness, can effectively reduce annealing time. Very low in unsaturated hydrocarbons, good oxidation stability, long service life, basically odorless, more friendly to human body and environment.

Description

technical field [0001] The invention belongs to the technical field of coal chemical industry, in particular to a method and application for preparing high-quality aluminum foil rolling base oil. Background technique [0002] Aluminum foil is widely used in wire and cable, instrumentation, aviation, food, pharmaceutical packaging, air conditioning, etc. It has become an indispensable material in production and life, and its consumption is increasing day by day. For the aluminum foil rolling process, rolling oil is one of the three major elements of aluminum processing and production. In aluminum rolling oil, base oil is the main component, usually accounting for 93-95%. Its performance is directly related to the smooth progress of aluminum production and the quality of the aluminum foil surface after rolling. Therefore, the quality of base oil plays a decisive role in the production process and product quality of aluminum processing. [0003] A good aluminum rolling base o...
