A kind of environment-friendly type alkane rubber oil and preparation method thereof

Abstract

The invention relates to an environment-friendly alkane rubber oil and a preparation method thereof. The environment-friendly alkane rubber oil is composed of the following components by weight: minus 35-45 parts of second-line dewaxed oil, 45-55 parts of minus fourth-line dewaxed oil, 1-20 parts of lightly deasphalted dewaxed oil; Wax oil, four-line dewaxed oil and light deasphalted dewaxed oil are respectively obtained by solvent refining and dewaxing treatment from second-line-reduction distillate oil, fourth-line distillate oil and light deasphalted oil; the light deasphalted oil The preparation includes: deasphalting and settling the vacuum residue in sequence. The rubber oil is made by blending dewaxed oil with reduced second line, dewaxed oil with reduced fourth line and light deasphalted dewaxed oil in a certain proportion, and its C P Content ≥ 50%, kinematic viscosity at 100°C is 10.15‑11.87mm 2 / s, light color in appearance, good stability, less volatilization, good compatibility with rubber, and exhibits excellent processability, operability and lubricity in rubber processing.

Description

technical field [0001] The invention belongs to the field of rubber processing aids, and in particular relates to an environment-friendly alkane rubber oil and a preparation method thereof. Background technique [0002] Oils used in rubber synthesis or rubber processing are collectively referred to as rubber oil. As an important additive, rubber oil is widely used in the rubber industry. After the rubber is filled with oil, the processability and use performance are improved, while 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. In general, those whose carbon atoms account for more than 50% of the total oil's carbon atoms are called paraffin-type rubber oils; those whose ring carbon atoms are 30-40% are called naphthene-type rubber oils. Rubber oil; those with more than 35% aromatic ring carbon atoms are called aromatic rubber oi...
