Abstract

The invention relates to a method for producing high-arene environment-friendly rubber oil. The method comprises the steps of taking heavy-solvent extract oil of a lubricating-oil solvent-refining device as raw material, adding an auxiliary agent to the raw material and then refining solvent, wherein the heavy-solvent extract oil has the flash point higher than 200 DEG C, the kinematic viscosity greater than 15.0 mm<2>/s at 100 DEG C and the CA value greater than 35.0 percent; the auxiliary agent is single-hydrocarbon or light-hydrocarbon oil with low density, low viscosity and boiling point between 80 and 300 DEG C; the solvent is N-methyl pyrrolidone, phenol or furfural; a refining tower has the temperature between 50 and 100 DEG C on the top and has the temperature between 30 and 100 DEG C on the bottom; and the mass ratio of the raw material to the auxiliary agent to the solvent is 1.0:0.1-0.5:2.0-5.0. Refined oil is high in arene content; the CA value of the refined oil is above 19.0 percent; the arene content of the refined oil is greater than 50.0 percent; the PCA content of the refined oil determined by an IP346 method is less than 3.0 percent; the benzopyrene of the refined oil is less than 1 PPM; and the total content of eight specific polyaromatic hydrocarbon is less than 10 PPM.

Description

technical field [0001] The invention relates to a production method of high-aromatic environment-friendly rubber oil used in the rubber industry and meeting the requirements of EU environmental protection standards. Background technique [0002] Aromatic rubber oil, referred to as aromatic oil, is a processing aid widely used in rubber and tire production industries. It is mainly used to improve the dispersion of other compounding agents in rubber processing, improve the flexibility, plasticity, calendering and extrusion of rubber. It can save power consumption during mixing, improve the physical and mechanical properties of the compound, and reduce production costs. Aromatic oil is generally produced directly from the by-product of the lubricating oil solvent refining unit - extracted oil, and it is required to have a high aromatic content in terms of product indicators. However, with the worldwide attention to environmental protection issues and the in-depth research on t...
