Embodiment 1

[0061] Example 1 shows an example of the strip-shaped lubricating material that is suitable for the present invention and is experimentally prepared for dry wire drawing. Comparative Example 1 shows the powder lubricant that is not applicable to the present invention and is used for dry wire drawing. Comparative Example 2 shows The strip-shaped polyethylene that is not applicable to the present invention has been eliminated.

Embodiment 1）

[0063] In a reaction vessel equipped with a stirring device, 75 parts by weight of industrial stearic acid were heated / melted under stirring, and then 25 parts by weight of slaked lime were added. This mixture was heated / stirred continuously until viscous. When the mixture becomes hard, stop heating / stirring, take out, cool and grind, so that its 500 mesh molecular sieve passing rate is about 60%, thus obtaining a calcium-based lubricant as a saturated fatty acid metal salt. 70 parts by weight of the obtained saturated fatty acid metal salt and 20 parts by weight of polyethylene as a thermoplastic resin were heated / kneaded at 180° C. with a hot kneader (trade name: Labo Plasto Mill). The obtained solid was formed into a sheet having a film thickness of 0.5 mm or less by a heating type press, and then cut into a tape having a width of 8 mm with a slicer, thereby obtaining a tape-shaped lubricating material for dry wire drawing.

Abstract

Provided is an innovative band-shaped lubricating material for dry wiredrawing which not only can be used under severe wiredrawing conditions, such as high-temperature high-pressure high-speed conditions, like conventional powdery or granular lubricants for dry wiredrawing, but also can accommodate both diameter reductions to a wide range of wire diameters ranging from a small to a large diameter and a wide range of wire speeds ranging from a low to a high speed. The lubricating material is not limited in the shapes of works, is excellent in terms of lubricity, conformability, spreadability, adhesion, heat resistance, processability, workability, safety, durability, productivity, and other function, is effective in improving the working environment, and is friendly to the global environment. This band-shaped lubricating material for dry wiredrawing is a material comprising a film which comprises 10-90 wt.% metal salt of a saturated fatty acid and 10-90 wt.% thermoplastic resin.

Description

technical field [0001] The present invention relates to a strip-shaped lubricating material for dry wire drawing, which is used to maintain a temperature-maintained processing state by preventing the Sintering as produced by direct contact between the parent material of a wire material or a rod and a die. Background technique [0002] Powder or granular lubricants for dry wire drawing are widely used in wire drawing. In wire drawing, the base material of a thick-diameter wire or rod made of steel or non-ferrous metal is pulled out from the hole of a section steel such as a die, and the diameter is reduced into a thin-diameter wire or rod, and plastically deformed. This lubricant for dry wire drawing is used to prevent direct contact between the base material and the die, thereby facilitating sliding to maintain a stable processing state. [0003] For example, Patent Document 1 discloses a borate-free lubricant for dry wire drawing that includes a metal salt of a saturated ...
