Abstract

The invention provides a lubricant composition of metal materials for water-based plastic processing. The composition is good in lubrication, ablative resistance and rust resistance. Plastic processing like steel or stainless steel forging can be conducted even without convesion coating. Due to the lubricating coating is water-based, coating can be fully removed only by water, and thereby good coating removement is achieved. The lubricant composition comprises water, water soluble polymer compound (a), inorganic metal salt (b), wherein the water soluble polymer compound (a) and the inorganic metal salt (b) are dissolved or dispersed in water, and the weight ratio (b) / (a) between the water soluble polymer compound (a) and the inorganic metal salt (b) is in the range of 0.1-5.

Description

technical field [0001] The present invention relates to a water-based lubricant composition for plastic processing of metal materials used for the plastic processing of metal materials such as steel, stainless steel, titanium, aluminum, copper alloys, and magnesium alloys. Background technique [0002] In the plastic processing of metal materials, oil-based lubricants that contain sulfur compounds, phosphoric acid compounds, organic acids, chlorine-containing compounds, synthetic esters, greases, metal soaps, etc. are added to base oils such as mineral oils. For example, oil-based lubricants for plastic working of aluminum alloys or non-ferrous metals obtained by adding alkylphosphonic acid derivatives synthesized from olefins and phosphorous acid to base oils are known (see Patent Document 1). However, although this lubricant can be used for aluminum alloys or non-ferrous metals, when it is used for plastic processing of steel or stainless steel under severe processing cond...
