Method for producing environment-friendly rubber softening oil

The invention relates to a method for producing environment-friendly rubber softening oil. The method is characterized by comprising the following steps: decompressing and distilling mineral oil; adding a catalyst into cut fraction at a temperature of between 280 and 340 DEG C to carry out a high-pressure hydrogenation reaction; adding the obtained product into carclazyte to be refined, and carrying out vacuum filtration to obtain refined mineral oil; treating bottom oil of a vacuum tower by the conventional propane deasphalting process to obtain an asphalt solution; distilling the asphalt solution under reduced pressure, taking cut fraction at a temperature of between 270 and 330 DEG C to be oxidized to obtain oxidized asphalt; mixing and stirring the obtained refined mineral oil and the oxidized asphalt in proportion by weight of 2.5-3.5:1.2-1.5 at a temperature of between 50 and 80 DEG C. The environment-friendly rubber softening oil has the advantages that the softening property, the compatibility and the intermiscibility are the same as or similar to the prior product high aromatic oil, but as the rubber softening oil does not contain or contains trace polycyclic aromatic hydrocarbon, so the rubber softening oil does not have carcinogenicity, does not pollute human body and environment, and meet the requirement of environment-friendly rubber extending oil.
