Abstract

The invention discloses environmental-friendly rubber filling oil and a preparation method thereof. The method comprises the following steps of: (1) hydrotreating a vacuum cut 3 distillate to obtain hydrotreating oil; (2) extracting the hydrotreating oil in an extraction tower for the first time to obtain raffinate at the tower top of the extraction tower, and recycling a solvent to obtain primary refined oil; preparing extract at the tower bottom of the extraction tower, and recycling the solvent to obtain primary extract oil; (3) extracting the primary refined oil into the extraction tower for the second time to obtain the raffinate at the tower top of the extraction tower, and recycling the solvent to obtain secondary refined oil; preparing extract at the tower bottom of the extraction tower, and recycling the solvent to obtain secondary extract oil, that is to say, environmental-friendly rubber filling oil. The environmental-friendly rubber filling oil, provided by the invention, has the advantages of high aromatic hydrocarbon content, good compatibility with the rubber and excellent processing performance, the mass percentage composition of the aromatic hydrocarbon reaches 19-26%, the environmental-friendly rubber filling oil can be used in a tire manufacturing process, and excellent performances such as good wet traction and the like can be given.

Description

Technical field [0001] The invention relates to an environment-friendly rubber oil filling oil and a preparation method thereof, and belongs 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 advent 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 formulated a timetable to restrict the use of aromatic oil in tires and prohibit the sale of tires using this oil in the region. As a result, some tires exported abroad must use environmentally friendly rubber oil to survive in the market. Therefore, tire export companies have a huge market demand for environmentally friendly rubber oil. However, such products abroad are expensive and the supply is...
