Method of using ionic liquids to improve the lubrication of chains, steel belts, wheel bearings, roller bearings, and electric motors

A method of enabling operation of chains, steel belts, wheel bearings, roller bearings, binding rods, wood presses, chain carpets, film stretching machines, drying or polymerization ovens in the glass wool, rockwool and plasterboard industry, sliding bearings (contacts) and electric motors for at least 48 hours by reducing the evaporation loss and the lackification tendency of a lubricant, comprising the steps of:

• applying a liquid lubricant having a kinematic viscosity at 40° C. between 50 mm2/sec and 1000 mm2/sec and comprising a mixture of
• (a) 99.3 to 30 weight % of a base oil or a base oil mixture of at least one synthetic oil, group III oils, native oils;
• (b) 0 to 50 weight % of a polymer or polymer mixture based on polyisobutylene, which can be partly or fully hydrogenated;
• (c) 0.1 to 2.0 weight % of an ionic liquid or mixtures of ionic liquids;
• and
• (d) 0.5 to 10 weight % of additives or additive mixtures;
• and
• operating said one of chains, steel belts, wheel bearings, roller bearings, binding rods, wood presses, chain carpets, film stretching machines, drying or polymerization ovens in the glass wool, rockwool and plasterboard industry, sliding bearings (contacts) and electric motors for at least 48 hours without lackification of the lubricant.
