The prospects of obtaining plastic greases from secondary hydrocarbon raw material

Abstract

The paper presents the results of producing lubricating grease from industrial and household waste in the laboratory. Partially prepared diesel engine oil SAE 10W-40 was used as a dispersion environment, and high and low pressure polyethylene (household polyethylene bags used) was used as thickener. It has been established that by using selected base oil, thickener and anti-wear additive DF-11, recy-cling oils can be obtained, which will be classified according to DIN 51502 to K2PF-30 and K3PF-30. It is proposed to expand the raw material base for the production of recycling oils through the using of waste industrial, hydraulic, transmission oils, as well as high-boiling petroleum fractions extracted from oil sludge or acidic tar and selective waste distillate oils. On the basis of the analysis of the researching results, it was established that on the basis of exhausting motor oil and polyethylene with the addition of additives of different functional purpose, it is possible to obtain a number of antifriction plastic lub-ricants used in swing bearings, railway and protective greases that can be used in the range of oper-ating temperatures, on average up to 100ºC.
