Abstract (en)
[origin: WO2009095373A1] The invention relates to a method for preparing metal workpieces for cold forming by first applying a phosphate layer and then applying a lubricant layer which has a major content in organic polymer material. The phosphate layer is formed by an aqueous acidic phosphating solution having a major content in calcium, magnesium or/and manganese and phosphate. The lubricant layer is formed by contacting the phosphated surface with an aqueous lubricant composition which has a content in organic polymer material based on ionomer and optionally also non-ionomer, the organic polymer material used predominantly being monomers, oligomers, co-oligomers, polymers or/and copolymers based on ionomer, acrylic acid/methacrylic acid, epoxide, ethylene, polyamide, propylene, styrene, urethane, the ester(s) or/and salt(s) thereof. The invention also relates to the corresponding lubricant composition, to the lubricant layer produced thereof and to its use.
