Abstract

The possibility of obtaining a new class of the bases of lubricants by modifying the natural fat molecule by a fragment of a link of synthetic polymer - polyethylene terephthalate is considered. The influence of thickeners of various chemical nature is considered: paraffin P400, beeswax, aerosil 200, modified bentonite, sodium stearate and lithium stearate on antifriction characteristics of PET-acylglycerol based on beef fat. The influence of fillers, namely: aerosil 200, modified with quaternary ammonium salts bentonite clay (particle size is 20 nm), talc, graphite and molybdenum disulphide on the value of static shear stress and anti-wear properties are considered
