Problems solved by technology

Among the three environmentally friendly rubber oils, TDAE products have the highest aromatic content, CA (3） When the value is above 20.0%, the difference between the composition and aromatic oil is the smallest, and the compatibility with rubber is the best; the aromatic content of MES and NAP is relatively low, and the CA value is about 12.0%, which is limited in use.
Due to the large investment and low product yield, the production cost of the product is high, and it is difficult to meet the user's demand for environmentally friendly rubber oil with high quality and low price. Rubber oil production cost becomes necessary

Embodiment 1

[0014] Compound 1 lubricating oil furfural refined extraction oil with a lubricating oil distillate to obtain 1# compounding and 2# compounding 2, which are used as raw materials, and furfural is used as a refining solvent in the laboratory pilot extraction device After multi-stage reverse contact refining, the yields were 59.8%, 55.2%, and the CA values ​​were 22.3%, 24.9%, respectively. Eight kinds of polycyclic aromatic hydrocarbons met the requirements of EU environmental protection regulations 2005 / 69 / EC. High-aromatic environment-friendly rubber oil, The yield is 20-27 percentage points higher than that of the environmentally friendly rubber oil obtained by refining the 1# extracted oil alone.

Embodiment 2

[0016] 2# lubricating oil furfural refined extraction oil is compounded with a lubricating oil distillate to obtain 1# compound compound and 2# compound compound, which are used as raw materials, and furfural is used as a refined solvent in the laboratory pilot extraction device Through multi-stage reverse contact refining, yields of 57.2% and 46.6%, CA values ​​of 15.2% and 19.9% ​​respectively, and 8 kinds of polycyclic aromatic hydrocarbons that meet the requirements of EU environmental regulations 2005 / 69 / EC are obtained. , and the yield is 33-43 percentage points higher than that of the environmentally friendly rubber oil obtained by refining the extracted oil from 2 lubricating oil furfural.

[0017] Examples 1 and 2 use raw materials, compound ingredients and pilot test raffinate properties are shown in Table 1-Table 7 respectively.

Abstract

The invention relates to a production method of high-performance environment-friendly rubber oil. The raw materials for producing the environment-friendly rubber oil are two combinations of petroleum products, one is lubricating-oil solvent refining extract oil with suitable viscosity and flash point and a higher aromatic content, and the other is a lubricating-oil distillate oil with suitable viscosity and flash point and a higher cyclane content and a higher aromatic hydrocarbon content. By taking the combined raw materials as raw materials for production of the environment-friendly rubber oil, and employing a conventional lubricating oil refining technology, the environment-friendly rubber oil, which has a CA value of 15.0-25%, the aromatic content of 40.0-55% , a benzopyrene concentration of less than 1 mu g / g and the total content of eight specific polycyclic aromatic hydrocarbons of less than 10 mu g / g, and completely reaches environment-protecting index requirements of EU environment-protecting directives 2005 / 69 / EC, can be trial-produced; and the environment-friendly rubber oil of the invention is higher in yield by 20-30 percent points than an environment-friendly rubber oil prepared by taking pure lubricating oil refining extract oil as a raw material.

Description

technical field [0001] The invention relates to a production method of high-performance environment-friendly rubber oil suitable for oil-extended rubber and tire industry Background technique [0002] Rubber oil is a special processing oil used in the production of oil-extended rubber and tires. It is usually called rubber extension oil for the production of oil-extended rubber, and it is usually called rubber operation oil for tire production and processing. After the rubber is filled with oil, it can endow the rubber with good processing performance, tensile performance and wear resistance, and also has the characteristics of small low-temperature rebound value, excellent wet skid resistance, low noise and strong grip; it is used in tire production Operating oil can improve the dispersibility of other ingredients in rubber processing, improve the flexibility, plasticity, calendering and extrusion performance of the rubber, save power consumption during mixing, and improve ...
