Lubricant for metal forming, in particular for forming steel, and a process for producing the forming lubricant

摘要

The invention relates to a forming lubricant for iron materials, in particular for forming steel. According to the invention, the forming lubricant contains at least one mineral which has a layer structure and an agent for modifying the layer structure. The mineral is expediently swollen, delaminated and / or exfoliated by means of the modifying agent. The modifying agent is or preferably contains a surfactant, which preferably comprises a soap and / or an amine. In one embodiment of the invention, the surfactant is a water-soluble soap, preferably an alkali or alkaline earth salt of a fatty acid, which preferably has a chain length of at least ten carbon atoms. The mineral is expediently a sheet silicate, preferably kaolin or a mineral of the mica group. The invention also relates to a method for producing the forming lubricant and a molded body coated with the forming lubricant.
