Abstract

The invention discloses a method for producing environment-friendly rubber oil through blending method. The method provided by the invention comprises the following steps that firstly extracting decompressed residual oil with solvent to obtain deasphalted oil, wherein the solvent for extraction is propane, the ratio by volume of the solvent and the decompressed residual oil is (6-8):1, and the extraction conditions are that the temperature of a tower top is 60-95 DEG C, the temperature of a tower bottom is 50-80 DEG C, and the pressure is 2.8-7.0 MPa, secondly mixing deasphalted oil obtained in the first step with naphthenic oil for 30-120 min with 70-90 DEG C to obtain environment-friendly rubber oil, wherein the mass ratio of the deasphalted oil and the naphthenic oil is (0.2-0.6):(0.8-0.4). The environment-friendly rubber oil produced by the invention accords with the environment-friendly instruction requirement of EU 2005 / 69 / EC, wherein aromatic-carbon rate is 12%-18%, the content of PCA is smaller than 3%, the content of aromatic hydrocarbons is high, and the rubber oil is environment-friendly, nontoxic, and has no carcinogenic effect. The environment-friendly rubber oil can be used as succedaneum of existing aromatic oil, and has great economic values.

Description

technical field

[0001] The invention relates to a method for producing environment-friendly rubber oil by blending. Background technique

[0002] At present, polycyclic aromatic compounds (abbreviated as PCA) have become the organic pollutants concerned by environmental protection and standard organizations all over the world. Aromatic oils widely used in the rubber and tire industries contain a large amount of these substances, which are harmful to the human environment. According to the 2005 / 69 / EC directive signed by the European Union, since January 1, 2010, the use of toxic aromatic oil in tires entering the EU market will be completely prohibited. Both the United States and Japan have also established timetables for restricting the use of aromatic oil in tires and prohibiting the sale of tires using this oil in the region. Therefore, various export tire manufacturers are actively planning to replace aromatic oil with environmentally friendly rubber oil.
