Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application claims the benefit of provisional application Ser. No. 61/691,054 filed Aug. 20, 2012, the entirety of which is hereby incorporated herein by reference.
    • FIELD OF INVENTION
  • The present application relates to lubricants used in industrial processes and in particular to processes and methods of making silicone lubricants for use with conveyor belts and related machinery.
    • BACKGROUND
  • Dry silicone lubricants have a number of industrial uses. For example, dry silicone lubricants are used as conveyor lubricants in the beverage industry. These dry silicone lubricants are typically sold as ready-to-use (RTU) products. Often, they are used in relatively small amounts to form a lubricant film on a conveyor. The use of dry silicone lubricants helps to substantially reduce or eliminate the dangers of wet floor hazards from the use of water-based or water-intensive lubricants. Further, use of dry silicone lubricants reduces water costs and sewage costs as well as reducing chemical waste.
  • Nevertheless, dry silicone lubricants can be expensive (in particular when compared to certain water-based lubricants), and the formation of biofilm from dry lubricants on a conveyor surface (for example) presents certain challenges. Therefore, a need is felt for a way to reduce the costs associated with the use of dry silicone lubricants and for dealing with problems associated with biofilm formation.
  • In the current state of the art, U.S. Pat. No. 7,371,712, assigned to Ecolab Inc., of Saint Paul, Minn., discloses methods wherein the passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts and with relatively low or no water content, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.
  • U.S. Pat. No. 7,592,296, assigned to JohnsonDiversey, Inc., of Sturtevant, Wisconsin, discloses conveyor track lubricant composition and methods comprising use of siloxane oil and a spreading agent, such as a trisiloxane spreading agent. The lubricant compositions may also contain biocide materials and stress crack resistance materials.
  • U.S. Pat. No. 7,915,206, assigned to Ecolab Inc., discloses a method for lubricating the passage of a container along a conveyor passage of a container along a conveyor that is lubricated by applying to the container or conveyor a composition comprising a water-miscible silicone material wherein the composition has good wetting to polyethylene terephthalate surfaces. The compatibility of the lubricating composition with polyethylene terephthalate is increased because the wetting of the composition to polyethylene terephthalate is improved.
  • U.S. Pat. No. 8,211,838, assigned to Ecolab Inc., discloses methods in which the passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricant composition comprising a water-miscible silicone material having a silicone emulsion wherein the silicone emulsion contains less than 500 ppm of a triethanolamine salts of alkyl benzene sulfonic acid compounds.
  • WO 2009/120768, filed by JohnsonDiversey, Inc., discloses a method of lubricating a conveyor belt wherein a lubricant concentrate containing at least one oil is employed in a dry lubrication process. Afterwards, a liquid composition having a pH value=5 is applied to the surface of the conveyor belt on which the lubricant concentrate has been applied earlier.
