Abstract

The invention provides an environment-friendly tire rubber oil and a preparation method thereof, and relates to the technical field of petroleum product processing. The preparation method of the environment-friendly tire rubber oil comprises the following steps: mixing the vacuum fraction of paraffin-based crude oil with the aromatic hydrocarbon extract oil of the vacuum fraction of naphthenic crude oil to obtain mixed wax oil; refining the mixed wax oil with furfural to obtain The raffinate oil is extracted and the furfural solvent and light components with a boiling point less than 400° C. are removed from the raffinate oil to obtain an environment-friendly tire rubber oil. In the present invention, by introducing the decompression fraction of paraffin-based crude oil, on the one hand, the selectivity of the furfural extraction process is improved, and on the other hand, the mass transfer effect of the traditional naphthenic furfural extraction oil for solvent refining is improved, thereby improving environmental protection tire rubber oil The yield, and can also increase the content of aromatics and C A value.

Description

technical field [0001] The invention belongs to the technical field of petroleum product processing, and in particular relates to an environment-friendly tire rubber oil and a preparation method thereof, in particular to a process method for preparing environment-friendly tire rubber oil by using mixed wax oil. Background technique [0002] Rubber filler oil is a special petroleum product added in the rubber production process, which can significantly improve the physical and chemical properties and processing properties of rubber. It is also called rubber processing oil or rubber softener when it is applied in the manufacturing process of rubber products, or rubber oil for short. . Aromatic-based rubber oil has been widely used in the production of oil-extended rubber and tires at home and abroad because of its high aromatic content and good compatibility with rubber, which can endow tires with good performance and low cost. However, aromatic-based rubber oil contains a la...
