Lubricating greases containing lignosulfonate, the production thereof, and the use thereof

摘要

The invention relates to lubricating greases that contain calcium lignosulfonate, comprising a base oil, calcium soaps, calcium lignosulfonate having average molecular weights (weight average) of greater than 10000 g/mol, optionally in addition to further alkaline earth lingosulfonates, which can be produced by heating to greater than 120 °C while reacting and while driving out low-boiling components to produce a basic grease and cooling and adding base oil and optionally additives while mixing, to a corresponding method, and to the use of the lubricating greases containing calcium lignosulfonate.
