Description

  • The present invention is directed at a water-based lubricant which is preferably free of oils. The water-based lubricant according to the present invention comprises water, at least one organic polymer and at least one polyhydric alcohol.
  • Today, many applications involving moving or rotating objects require lubricants to prevent the work-pieces and tools from overheating and excessive wear. The state of the art in lubricants today are mineral oil based lubricants, however, these have suffered from recent drawbacks as oil is extracted from non-renewable resources and the prices of oil have been on the rise for a considerable time. Moreover, mineral oils have further disadvantages that their heat capacity is relatively low, so that the efficiency in dissipating heat away from a work-piece is low as well. Further disadvantages of conventional oil based lubricants are that they are usually harmful to the health of the user and flammable. This requires technical efforts for occupational safety, fire-safety and disposal. Moreover, oil based lubricants have proven difficult to remove from soiled workers clothes.
  • GB1563789 teaches an aqueous lubricant composition, the lubricant comprising at least one alkali metal salt of at least one aliphatic monocarboxylic acid, an at least partially water-soluble bactericide, and water. Such lubricant compositions can be used for the assembly of push-fit pipes.
  • There is still a need for alternative lubricants which are based on materials with a high heat capacity to improve the ability of the lubricant for dissipating heat away from a work-piece. In addition, there is a need for lubricants which are based on easily accessible base materials and which have a low flammability to improve worker safety. Finally, there is a need for lubricants that are easy to manufacture and handle, and easy to wash off from cloth, equipment, floors, skins, etc. The present application addresses these needs.
