OPTIMIZATION OF CONCENTRATION OF ANTIOXIDANT ADDITIVE IN PLASTIC LUBRICANT BASED ON RAPESEED OIL

Plastic lubricant with rapeseed oil dispersion medium is considered addition of diphenylamine antioxidant additive. Analysis tribotechnical, chemical and physicо-mechanical characteristics the obtained lubricants content additive from 0.5 to 10.0 wt.% carried out. The effect concentration temperature introduction on functional shown. A comprehensive method proposed for evaluating optimal using an integral indicator, according total characteristics. It noted that plastic a phase based complex calcium thickener, range introducing 85–95 °C at cooling stage, 1.0 wt.%. In this case, best combination finished product achieved. Based methodology taking into account experimental data, expert criteria it possible optimize diphenylamine, obtain given
