ABSTRACT:
This disclosure relates to a lubricant comprised of a mixture of a binder and a lubricating agent in a certain predetermined ratio. The binder is a wax type material having a melting point below the surface onto which the lubricant is applied and the lubricating agent is selected from a group consisting of talc, mica, whiting or Kaolin (China Clay).
This lubricant is specifically designed to be applied to a relatively hot surface during a manufacturing operation so that the binder melts to form a film on the surface with the lubricating agent trapped or encapsulated within the film. The binder solidifies on cooling and the film then acts as a lubricant on the surface of the product in its later manufacturing operations and is of such a nature that it does not interfere with the final properties of the product. This lubricant and method are particularly well suited to manufacturing processes wherein unvulcanized rubber compounds are shaped into assemblies that are then incorporated into end products and vulcanized; for example, tubes for pneumatic tires, tires and the like.
