  • Aqueous lubricant for saw chains
    Patent number: 4563294
    Abstract: This saw chain lubricant is composed essentially of water and a water-soluble antifreeze agent, as main constituents, and of corrosion inhibitors, wear inhibitors and adhesion promoters in a quantity which is effective in each case, the adhesion promoter being a water-soluble polyethylene glycol and/or a water-soluble acrylamide copolymer which contains sulfonic acid groups, the molecular weight of each being at least 500,000. In combination with this adhesion promoter, which is present in an amount of 0.05 to 1% by weight, the lubricant contains 5 to 50% by weight of a water-soluble polyethylene oxide/polypropylene oxide adduct having a viscosity of at least 300 mPa.s at 50.degree. C., as a special lubricant, percentages by weight relating in each case to the weight of the agent.
