Problems solved by technology

Both Chinese patents 201210048221.7 and 201210048263.0 use naphthenic distillates as raw materials, and produce C A Environmentally friendly rubber oil with a value of 19-26%, the product has good compatibility with rubber and excellent processing performance, but some low-value-added oil is still produced during the process
The process of one-stage hydrotreating and one-stage solvent refining reduces the yield of low-value-added extracted oil, but cannot produce high-aromatic and environmentally friendly rubber oil

Abstract

The invention discloses a high-aromatic hydrocarbon environmental-friendly rubber oil and a preparation method thereof. The preparation method comprises the following steps of: (1) carrying out hydroprocessing on naphthenic base reduced-pressure distillate oil to obtain solvent preprocessing oil; (2) diluting the solvent preprocessing oil by using a diluting solvent, then refining through a solvent to obtain extraction liquid at the bottom of a refining tower, and recovering the solvent to obtain extraction oil; and (3) hydroprocessing the extraction oil, then distilling, and then collecting distillates being higher than 380 DEG C, namely the high-aromatic hydrocarbon environmental-friendly rubber oil. The high-aromatic hydrocarbon environmental-friendly rubber oil disclosed by the invention is high in additional value, thereby greatly enhancing the integral economic benefit of naphthenic base distillate oil.

Description

technical field [0001] The invention relates to a high-aromatic environment-friendly rubber oil and a preparation method thereof, belonging to the technical field of petrochemical industry. Background technique [0002] In the production process of rubber products, about 30% rubber oil is usually added to the rubber. The addition of rubber oil not only improves the processing performance and use performance of rubber, but also reduces the production cost of rubber. [0003] As the world's calls for environmental protection are getting higher and higher, the application of green and environmentally friendly materials has attracted much attention. The European Rubber Industry Association (BLIC) and the International Synthetic Rubber Producers Association jointly announced that they will use non-toxic oil in tires, and On January 1, 2010, toxic rubber oil was completely banned in tire production. However, during the use of rubber oil, according to the principle of similar comp...
