High-temperature, water-based lubricant and process for making the same

This invention relates to a high-temperature, water-based lubricant and, more particularly, to a water-based graphite suspension useful in metal and mineral forming applications and a continuous process for making the same. A high-temperature lubricant comprising a water-base and minor effective amounts of borate, dextrin, graphite, xanthan gum, and an organic preservative. A powder for preparing a water-based high temperature lubricant is disclosed in which the powder comprises graphite and minor effective amounts of borate, dextrin, and xanthan gum. A continuous process for making the lubricant is also disclosed.
