LUBRICATING COMPOSITION CONTAINING VEGETABLE COMPONENT AND METHOD OF PRODUCTION OF VEGETABLE COMPONENT Russian patent published in 2008 - IPC C10M173/02 C10M159/02 C10M133/08 C10M129/08 C10M133/40 C10M135/10 C10M125/24 

FIELD: technological processes of cold plastic metalworking and machining.

SUBSTANCE: proposed composition contains the following components, mass-%: vegetable component (in terms of dry substance), 5-40; triethanol amine, 0.20-0.46; ethylene glycol, 0.60-0.82; sodium dodecyl sulfate, 0.20-0.25; sodium hydrophosphate, 0.20-0.25; oxyquinoline, 0.20-0.22; the remainder being water. For preparation of vegetable component, solid fraction of pig manure is preliminarily subjected to washing-off for complete removal of animal excrements, after which extraction by steam condensate is carried out at temperature of 150-170 C and pressure of 0.5-0.7 Mpa continued for 60-120 minutes and then extract is evaporated at temperature of 100-110 C to concentration of 40-70 mass-%.

EFFECT: enhanced stability; reduced corrosion activity and toxicity; improved tribological characteristics; facilitated procedure and low cost of method.
