Heat resistant lubricant used for drawing refractory metal and preparation method thereof

Abstract

The invention discloses a heat resistant lubricant used for drawing refractory metal and a preparation method thereof. The heat resistant lubricant comprises the following components by weight: 10-30% of graphite, 0.1-2% of dispersant, 0.3-5% of thickening agent, 0.1-15% of emulsifier, 0.5-10% of film forming agent, 2-5% of ammoniacal liquor with concentration of 25%, 0.1-1% of antiseptic, 0.1-2% of adhesive, 0.3-3% of surfactant and balance of water. The heat resistant lubricant has good adhesive force under high temperature and can not generate explosion and shedding, lubricity, thermal conductivity and surface antioxidation performance between the drawing material and a mold can be effectively increased, heat due to friction can be reduced, and usage life of the mold can be prolonged.

Description

technical field

[0001] The invention relates to additives used in the technical field of high-temperature wire drawing of refractory metals, in particular to a high-temperature-resistant lubricant for drawing refractory metals and a preparation method thereof. Background technique

[0002] Metal drawing is a plastic processing method that applies tension to a metal blank to pass through a die hole to obtain a product with the same cross-sectional size and shape as the die hole. It is the main method for producing pipes, bars, profiles and wires. The metal drawing method is divided into cold drawing, hot drawing and warm drawing according to the temperature of the metal during drawing; among them, cold drawing is the method used in the production of metal wire and metal wire, and is suitable for metal materials with low melting point and good ductility; In the drawing process, the metal wire needs to be heated before entering the die hole, which is mainly used for the drawing...
