Properties of base fluids for environmentally adapted lubricants

Abstract [en]

To stimulate development of high performing mechanical components the foundation SSF, “stiftelsen för strategisk forskning” has granted 25 Mkr to HiMeC. HiMeC is a national tribology research program. This master thesis is a small part of a bigger research project within HiMeC, called Matrix. The lubricants of tomorrow have to be both well performing and environmentally adapted. One way to produce those lubricants is to tailor made their molecular structure to get the expected properties. The relationship between physical and molecular properties has to be known in order to do so. This investigation takes us one step further against that aim. In this thesis, five different fluids suitable as base oils for lubricants are characterized. Examples of investigated properties are: viscosity- temperature-pressure-effects, thermal conductivity and heat capacity per unit volume. Lubrication capability is not included in this work. The chosen fluids are: Bis (2-etyl hexyl) sebacate, TMP oleat, TMP C8/C10, Trioctylmetan and 2,6,10,15,19,23-Hexamethyltetracosane. All measurements are performed at Luleå University of technology except those of thermodynamic properties who are made at Umeå University. The results from the tests are presented in this report and in a scientific paper, which is accepted for presentation at the World Tribology Congress in Vienna September 2001.
