Problems solved by technology

[0004] The rubber oil produced by the solvent refining method can guarantee the content of aromatic hydrocarbons, but in order to remove the polycyclic aromatic hydrocarbons in the rubber oil, multiple solvent refining is required, resulting in a low product yield, strict requirements on operating conditions, high processing costs, and the resulting Rubber oil still contains a small amount of PCA and eight polycyclic aromatic hydrocarbons (PAHs); the hydrogenation process will cause a large loss of aromatic content, resulting in poor compatibility between rubber oil and rubber
Therefore, in order to ensure that the rubber oil has a certain aromatic content, hydrogenation treatment and solvent refining are usually combined to produce environmentally friendly rubber oil. In the process of hydrogen treatment, the product will contain more condensed ring aromatics, and then solvent refining to remove part of the fused ring aromatics, the treatment procedure is cumbersome and the cost is high, and the finished product still contains a small amount of PCA and eight kinds of fused ring aromatics (PAHs)

Embodiment 1

[0020] Example 1 Preparation of naphthenic base oil

[0021] The viscosity is 6.5~16.0mm 2 / s (100°C), fractions of unsaturated chain hydrocarbons and monocyclic and polycyclic aromatic hydrocarbons with a distillation range of 350~480°C (in this fraction, fractions of unsaturated chain hydrocarbons and monocyclic and polycyclic aromatic hydrocarbons account for the total weight of the fractions) 30~55% of ) as raw material, through the hydrotreating reactor, the reaction temperature is 320~380℃, the reaction pressure is 15~17MPa, the reaction hydrogen oil volume ratio is 1000~3000, and the space velocity is 0.2~0.6 / h ; Then through the dewaxing reactor, the reaction temperature is 350~390℃, the reaction pressure is 15~17MPa, the reaction hydrogen oil ratio is 1000~3000, and the space velocity is 1.5~4 / h; and then through the hydrofining reactor, During the reaction process, the reaction temperature is 230~270℃, the reaction pressure is 15~17MPa, the reaction hydrogen oil rat...

Embodiment 2

[0026] Raw material ratio: in terms of mass percentage, 3-ring methyl polybenzyltoluene derivative Friedel-Craftene 100 (FC0100) (purchased from Shanghai Zexi Chemical Technology Co., Ltd., the team of Fu Ke-Xi, Fu Ke-Xi, China) 10%, optical Thermal composite stabilizer (UV light absorber and heat stabilizer mixed at 1:1, stored in an oven at 60°C for 48 hours before use) accounted for 0.04%, and the balance was the viscosity prepared in Example 1 (100°C) 6cSt naphthenic base oil.

[0027] According to the above weight ratio, the 3-ringmethylpolybenzyltoluene derivative is added to the naphthenic base oil, and the mixture is uniformly stirred at 800 rpm at 50-80° C. for 0.5 h. Then heat up to 100°C, add photothermal composite stabilizer, and stir evenly at 500 rpm for 0.3h to obtain the green rubber oil.

Embodiment 3

[0029] In this embodiment, the preparation method of naphthenic base oil is the same as that in Embodiment 1.

[0030]The difference from Example 1 is that in the raw material of color-friendly rubber oil prepared in this example, in terms of mass percentage, 3-ringmethyl polybenzyl toluene derivative Friedel-Crossene 100 (FC0100) accounts for 10%, and the photothermal composite is stable agent (ultraviolet light absorber JL-900 and heat stabilizer JL-300, mixed at a mass ratio of 5:1 and stored in an oven at 60°C for 48 hours before use) accounted for 0.04%, and the others were viscosities prepared by the method in Example 1 (100°C) is a 10cSt naphthenic base oil.

Abstract

The invention discloses environment-friendly rubber oil and a preparation method thereof. The rubber oil is prepared from an aromatic hydrocarbon derivative, a photo-thermal compound stabilizer and naphthenic base oil, wherein the CN content of the naphthenic base oil is larger than 40 percent, and the CA content is 0. An added alkyl poly-benzyl methylbenzene derivative is odorless, non-toxic and harmless, and is free from carcinogenicity, teratogenicity and mutagenicity; the CA content of the prepared environment-friendly rubber oil is up to 1 to 13 percent, and the aromatic hydrocarbon content is up to 5 to 30 percent; the environment-friendly rubber oil is healthy to human bodies, is harmless to the environment, has high viscosity and a low flow point, and plays a good role in enhancing the physical performance and cold resistance of oil-extended rubber after filling into the rubber.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to an environment-friendly rubber oil and a preparation method thereof. Background technique [0002] As the world's calls for environmental protection are getting higher and higher, the application of green environmental protection materials has attracted much attention. The harm of traditional high-aromatic rubber oil to human health and the pollution to the environment have attracted great attention from governments and researchers in various countries. According to the principle of similar compatibility, if rubber oil should have good compatibility with rubber, it is required that the rubber oil should have a higher content of aromatic hydrocarbons. However, polycyclic aromatic hydrocarbons (PCA) have become recognized organic pollutants in the world, benzo(a)pyrene, benzo(a)anthracene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(j ) fluoranthene, benzo(a)pyrene, be...
