Abstract

The invention discloses environment-friendly rubber oil and a preparation method thereof. The method comprises the following steps: (1) hydrotreating cut-3 distillate oil to obtain hydrotreated oil; (2) filling the hydrotreating oil into an extraction column for primary extraction to obtain raffinate on the top of the extraction column, recovering a solvent to obtain primary refined oil and obtain an extracting solution at the bottom of the extraction column, and recovering the solvent to obtain primary pumping oil; and (3) filling the primary pumping oil into the extraction column for secondary extraction to obtain the raffinate on the top of the extraction column, and recovering the solvent to obtain secondary refined oil namely the environmental-friendly rubber oil and obtain the extracting solution at the bottom of the extraction column, and recovering the solvent to obtain secondary pumping oil. The environment-friendly rubber oil provided by the invention has high aromatic hydrocarbon content, and the masses of aromatic carbon accounts for 18-27%. The environment-friendly rubber oil has good compatibility with rubber and excellent processing performance. The environment-friendly rubber oil can be used in the tyre manufacturing process and can endow excellent performances to the tyre, such as good slippery resistance.

Description

technical field [0001] The invention relates to an environment-friendly rubber oil and a preparation method thereof, belonging to the field of petroleum product processing. Background technique [0002] At present, the domestic rubber processing industry represented by tire production is developing rapidly, and the demand for rubber oil is also increasing year by year. However, with the arrival of 2010, the use of aromatic oils with excessive polycyclic aromatic hydrocarbons has been completely banned in tires entering the EU market. The United States and Japan have also successively formulated timetables for restricting the use of aromatic oil in tires and prohibiting the sale of tires using this oil in the region. This has led to the fact that some tires exported abroad must use environmentally friendly rubber oil to survive in the market. Therefore, various tire export companies have a huge market demand for environmentally friendly rubber oil. However, such products in...
