Zusammensetzung eines wäßrigen Trennschmiermittels für Formen zum plastischen Formen

A composition comprising (a) fine spherical particles of an inorganic substance such as alumina, (b) an aqueous adhesive agent such as a petroleum resin emulsion, and water. It is preferred for better effect that the composition further comprises one or more selected from among (c) a wisker, (d) a powder of an inorganic substance in a form of a scaly crystal, (e) a powder of a metal hydroxide or an inorganic substance having bound water, and (f) a lubricant aid. The composition is free from problems of the occurrence of environmental pollution and the risk of misoperation of an automatic machine, which accompany a conventional graphite lubricating and releasing agent, and that of the danger of smoking or firing, which accompanies a conventional lubricating and releasing agent dispersed in an oil, and is useful as an aqueous lubricating and releasing agent for hot or cold forging using a non-graphite inorganic substance, which is free from occurrence of the deposition on a mold and an under fill phenomenon.
