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.

Abstract translation: 本发明涉及一种以一定的比例由粘合剂和润滑剂的混合物组成的润滑剂。 粘合剂是一种蜡状材料，其熔点低于施加润滑剂的表面，润滑剂选自滑石，云母，茅草或高岭土（中国粘土）。 该润滑剂被特别设计成在制造操作期间施加到相对热的表面上，使得粘合剂熔化以在表面上形成膜，该润滑剂被捕获或封装在膜内。 粘合剂在冷却时固化，然后膜在其后续制造操作中作为产品表面上的润滑剂，并且具有这样的性质，即它不会干扰产品的最终性能。 该润滑剂和方法特别适用于制造方法，其中未硫化橡胶化合物成型为组合物，然后将其并入终产物并硫化; 例如，用于充气轮胎，轮胎等的管。
