Blending production method of aromatic hydrocarbon rubber extender oil

Abstract

The invention discloses a blending production method of aromatic hydrocarbon rubber extender oil; aromatic hydrocarbon oil is selected as a main raw material; based on performance parameters of the selected aromatic hydrocarbon oil and performance indexes of a rubber extender oil finished product, one or more than one of extract oil, vacuum cut distillate oil and recovered lubricating oil heavy fraction are selected as auxiliary raw materials; an optimized blending formula is obtained by calculation and small experiment; all the raw materials are mixed in a blending metering tank according to the formula so as to perform physical circulating blending and thus to perform large-scale production. The process flow is simple; the production operation is easy to control; the labor intensity is low; the product quality is stable; the production throughput is high; the production scale is easy to amplify; resources for high-quality aromatic hydrocarbon rubber extender oil production are effectively increased, and the production cost of the product is reduced. Specifically, by means of continuous reduced-pressure distillation and physical blending, no waste gas or sulfur-containing harmful gas is discharged; no waste water is discharged; no poisonous or harmful solvent is used in the production process; and the production method has outstanding environmental protection and energy saving effect.

Description

technical field [0001] The invention belongs to the field of oil refining and petrochemical industry, and mainly relates to the comprehensive utilization of petrochemical by-products and the large-scale processing scheme of high-quality rubber filling oil. Background technique [0002] Rubber filler oil is an important raw material in the rubber refining process, and its quality directly affects the quality of the refined rubber compound and the quality of rubber products. [0003] An ideal rubber extender oil must have the characteristics of stable properties, moderate distillation range, good stability, low volatility, high flash point, safety and reliability, and low wax content. At the same time, the carbon structure distribution (C A %, C N %, C P %) must be in a limited and reasonable range, only in this way can it have good compatibility with rubber. It can be seen that in the production process of rubber filler oil, attention must be paid to controlling its densit...

AI Technical Summary

Problems solved by technology

[0006] It is particularly noteworthy that there is a large demand gap for aromatic hydrocarbon rubber filler oil products. Many rubber, tire and other rubber product manufacturers import a large amount of aromatic hydrocarbon rubber filler oil products through imported rubber oil agents. The process of circulation such as packaging, transportation, and transfer is complicated, which is extremely unsuitable for the needs of large-scale production
