| Description |
The extreme pressure (EP), anti-wear and friction-reducing characteristics of some of the commercial additive
formulation and individual components on which these formulations are based have been studied and compared
to characteristics of the components synthesised from naturally available non-traditional vegetable oils and cashew
nut shell liquid that have been refined and partially hydrogenated to improve stability. It has been shown that
individual components from sulphurised and phosphosulphurised vegetable oils, esters and hydrogenated cardanol
(derived from cashews) have better anti-wear and friction-reducing characteristics than the sulphurised
olefins and alkylaryl phosphorothioates normally used as EP and anti-wear additives, while the load-carrying
characteristics of a number of the combination of these derivatives are comparable. It has been shown that all
these formulations are rapidly biodegradable and non-toxic in nature as compared to traditional EP, anti-wear and
friction-reducing additives, which fill in the category of slightly toxic to harmful.
It is possible to formulate energy-efficient EP gear oils that are fully biodegradable and non-toxic by a combination
of vegetable oil-based additives of sulphurised vegetable oils, phosphosulphurised methyl recinoleate
and phosphosulphurised hydrogenated cardanol amine borate, which meet all the performance characteristics of
US steel 224 eg 52100, M-50 AISI 1010 requirements,
