Environmentally-friendly alkane rubber oil and preparation method thereof

Abstract

The invention relates to environmentally-friendly alkane rubber oil and a preparation method thereof, wherein the environmentally-friendly alkane rubber oil comprises, by weight, 35-45 parts of pressure reducing second side dewaxing oil, 45-55 parts of pressure reducing fourth side dewaxing oil, and 1-20 parts of light deasphalting dewaxing oil, the pressure reducing second side dewaxing oil, thepressure reducing fourth side dewaxing oil and the light deasphalting dewaxing oil are respectively prepared by sequentially carrying out solvent refining and dewaxing treatment respectively on pressure reducing second side distillate oil, pressure reducing fourth side distillate oil and light deasphalting oil, and the preparation of the light deasphalting oil comprises: sequentially carrying outdeasphalting and sedimentation on pressure reducing residue oil. According to the present invention, the rubber oil is prepared by blending the pressure reducing second side dewaxing oil, the pressurereducing fourth side dewaxing oil and the light deasphalting dewaxing oil according to a certain ratio, has the CP content of more than or equal to 50% and the 100 DEG C kinematic viscosity of 10.15-11.87 mm<2> / s, has advantages of light appearance color, good stability, less volatilization and good compatibility with rubbers, and further has excellent processing property, excellent operability and excellent lubricity in rubber processing.

Description

technical field [0001] The invention belongs to the field of rubber processing aids, in particular to an environment-friendly alkane rubber oil and a preparation method thereof. Background technique [0002] The oils used in rubber synthesis or rubber processing are collectively referred to as rubber oils. As an important auxiliary agent, rubber oil is widely used in the rubber industry. After the rubber is filled with oil, the processing performance and service performance are improved, the output of rubber is increased, and the cost is reduced. [0003] Rubber oil is divided into paraffin type, naphthene type and aromatic type rubber oil according to its chemical composition. Under normal circumstances, those whose carbon number of paraffins accounts for more than 50% of the carbon atoms of the whole oil are called paraffinic rubber oils; those whose ring carbon atoms are 30-40% are called naphthenic rubber oils. Rubber oil; those whose aromatic ring carbon number is mo...
