Abstract

The invention relates to a production method of rubber filling oil excellent in stability. The production method comprises the following steps: sequentially charging decompression distilled oil of naphthenic crude oil and cycloalkane immediate crude oil, and light deasphalted oil into a hydro-treatment reaction area, a hydro-dewaxing reaction area and a hydro-refining reaction area; charging a hydro-refining product into an electromagnetic wave treatment area; removing a part of saturated polycyclic aromatic hydrocarbon under the irradiation of high-temperature electromagnetic wave; and charging a product which is obtained in the electromagnetic wave treatment area into a degumming unit to obtain a degummed fraction which is just the rubber filling oil product. The method disclosed by the invention has the advantages of improving the stability of the rubber filling oil without using noble metals for hydro-refining or adding additives, greatly simplifying the technological production procedures of the rubber filling oil and greatly reducing the device construction investment and the operation cost.

Description

technical field [0001] The invention relates to a production method of rubber extension oil, in particular to a production method of rubber extension oil with excellent stability. Background technique [0002] In order to improve some properties of rubber, mineral oil needs to be filled into synthetic rubber, so it is called rubber filling oil. As an auxiliary agent in the rubber industry, rubber filler oil can not only improve the plasticity of the rubber, reduce the viscosity of the rubber and the temperature during mixing, but also promote the dispersion and mixing of other ingredients, and lubricate the extrusion of the calendering , and can reduce the hardness of vulcanized rubber and improve its performance. At the same time, the addition of rubber filler oil can also increase rubber output, reduce costs, and improve the processing performance and use performance of rubber, which plays an important role in the rubber processing industry. [0003] Rubber extender oil ...
