Problems solved by technology

First, the consumption of oil sludge is low. The mass fraction of oilfield sludge used in the production of reclaimed rubber is 40-50%. The amount of oilfield sludge used is small, resulting in low sludge consumption, which is not conducive to the application of this technology in the oilfield sludge treatment industry. promotion; second, the amount of miscellaneous rubber powder is large, and the production cost of reclaimed rubber is high

Abstract

The invention belongs to the field of oil field oil sludge resourceful treatment, especially discloses reclaimed rubber prepared from oil field oil sludge as a main raw material, and also discloses a production method. The reclaimed rubber prepared from the oil field oil sludge is composed of the raw materials by the mass percentage: 50%-65% of oily sludge, 5%-20% of a waste tire rubber powder, 20%-40% of clay, 0.1%-0.4% of an activator 420, 0.1%-0.3% of ethylene tar, and 0.1%-0.3% of alkyl phenol disulfide. According to the reclaimed rubber prepared with oil field oil sludge, through formula optimization design, the content of the oily sludge is increased significantly, the consumption of the oil field sludge is increased, and the oil field oil sludge resourceful treatment effect is increased by 20% or more; with use of the waste tire rubber powder, the use amount is only 5%-20% and is significantly reduced, and the production cost is saved; the reclaimed rubber has relatively short reclaiming reaction time and has high degree of desulfurization, and the reclaimed rubber properties all reach national corresponding reclaimed rubber standards.

Description

technical field [0001] The invention relates to the technical field of oilfield oil sludge resource treatment, in particular to a reclaimed rubber prepared from oilfield oil sludge as a main raw material, and also relates to a production method thereof. Background technique [0002] Oilfield oil sludge or oil sludge mainly refers to a large amount of oily solid waste produced in the process of petroleum exploration, development and smelting. At present, my country has listed oil sludge as oily waste in the National Catalog of Hazardous Wastes. [0003] The treatment and disposal of oilfield oil sludge is a major scientific problem in the world. At the same time, the "National Cleaner Production Promotion Law" and "Solid Waste Environmental Pollution Prevention Law" require that oil sludge must be treated in a harmless manner. According to the State Council of the People's Republic of China No. 369 "Regulations on the Collection and Use of Sewage Discharge Fees" (implemented...
