Embodiment 1

[0025] Embodiment 1, the preparation of low-viscosity green rubber plasticizer

[0026] (1) Take Qinhuangdao 32-6 minus first-line distillate oil as raw material (see Table 1 for the properties of the raw material), add it to the reaction kettle, add 5% white clay by weight of the raw material at the same time, start stirring, and gradually heat to a temperature of 130°C, and keep it for 30min After the time is over, filter the clay to obtain refined oil from the clay.

[0027] (2) Distill and cut the refined clay oil obtained above, and collect components with an initial boiling point of 320° C. and a 97% distillation temperature of 380° C., which are low-viscosity green rubber plasticizers.

[0028] The performance parameters of the low-viscosity green rubber plasticizer prepared in this example are shown in Table 2.

Abstract

The invention discloses a preparation method of a low-viscosity green rubber plasticizer. The method includes the following steps that hargil is adopted to conduct hargil refining on naphthene-based first-vacuum-side-stream distillate oil, and refined oil is obtained after the hargil is removed; the refined oil is distilled and cut to remove light components and heavy components, and the low-viscosity green rubber plasticizer is obtained. According to physical and chemical parameters of the low-viscosity green rubber plasticizer, the chromaticity is lower than or equal to 1.1#, and the pour point is higher than or equal to 30 DEG C; the CA value is higher than or equal to 16%; the content of naphtho-[a] pyrene is lower than 1 mg / kg. According to the preparation method, the naphthene-based first-vacuum-side-stream distillate oil with low additional value is fully utilized to serve as the raw material, the low-viscosity green rubber plasticizer with high additional value is produced, and economic benefits are raised. The obtained low-viscosity green rubber plasticizer is light in color, low in pour point and high in aromatic hydrocarbon content. By means of the method, the additional value of the naphthene-based first-vacuum-side-stream distillate oil can be obviously raised, an obtained low-viscosity oil product can be used for rubber machining, and the method is particularly suitable for producing rubber products used in a low-temperature environment.

Description

technical field [0001] The invention relates to a preparation method of a low-viscosity green rubber plasticizer, which belongs to the field of petrochemical industry. Background technique [0002] At present, the domestic rubber processing industry represented by tire production is developing rapidly, and the demand for rubber oil is also increasing year by year. With the implementation of the European Union's "Directive on the Restriction of Polycyclic Aromatic Hydrocarbons (PAHs)" from January 1, 2010, the limits of 8 kinds of polycyclic aromatic hydrocarbons in rubber oil directly put into the market or used in the manufacture of tires are more stringent , in response to the European Union's environmental regulations, many oil companies at home and abroad are currently conducting research on the improvement and substitution of the high aromatic rubber oil being used. [0003] The current production of green rubber plasticizers mainly includes hydrogenation process and s...
