A production process of novel environmental-friendly biological rubber-tyre filling oil

Abstract

The invention mainly provides a production process of novel environmental-friendly biological rubber-tyre filling oil. The process combines hydrogenation, extraction and fractionation, and introduces a new idea of preparing rubber filling oil by adopting mineral oil and vegetable oil as raw materials. Conventional devices in the processing industry at present can be utilized. The process is mature in technique, simple in production procedures and low in cost. The produced environmental-friendly rubber filling oil allows the environmental protection performance of oil products to meet requirements of the European Union and is good in compatibility with rubber. Main indexes of the produced filling oil meet quality index requirements of environmental-friendly tyre oil.

Description

technical field

[0001] The invention relates to the technical field of rubber additives, in particular to a production method of environment-friendly bio-rubber tire filling oil, which is used for filling and processing of various rubbers. Background technique

[0002] Rubber extender oil is a special oil used in the production of oil-extended rubber. After the rubber is filled with oil, the processability and use performance can be improved, and at the same time, the output of rubber can be increased and the cost can be reduced. The output of natural rubber in my country is limited, and synthetic rubber occupies a large proportion in the rubber industry. With the advancement of my country's synthetic rubber technology and the increase in output, the output of oil-extended rubber is also increasing rapidly, so the demand for rubber-extended oil is also increasing day by day.

Embodiment 1

[0029] Experiments were carried out on a small pilot rig. The hydrogenation reactor is a 100ml fixed-bed hydrogenation reactor; the fractional distillation uses a real boiling point distillation device with 17 theoretical trays. The raw oils were mineral oil, mineral oil and vegetable oil (1:1), mineral oil and vegetable oil (3:1), mineral oil and vegetable oil (6:1). The Mo-Ni-P hydrogenation catalyst loaded on the amorphous aluminum silicate steroid in the 100ml fixed-bed hydrogenation reactor, its MoO Account for 20w% of the total weight of the catalyst, and NiO accounts for 9.2w% of the total weight of the catalyst, P2O5 accounts for 2.9w% of the total weight of the catalyst, and the rest is amorphous aluminum silicate steroid.

[0030] The catalyst has a pore volume of 0.38ml / g, a specific surface of 363m2 / g, and a spherical shape. The catalyst is presulfurized by conventional methods before use, and the process condition inspection test is carried out after its activit...
