Wearable, water-base, nano tungsten disulphide and isothermal forging lubricant and preparation method therefor

Abstract

The present invention discloses a wearable, water-base, nanometer tungsten disulphide and isothermal forging lubricant. The lubricant is prepared from the following raw materials in parts by weight: 7.4-7.6 parts of poly-alpha-olefin PAO6, 0.2-0.25 parts of a silane coupling agent kh5600, 8.2-8.4 parts of nano tungsten disulphide, 0.8-1 parts of carbon nanocapsules, 0.8-1 parts of nano-bentonite, 1-1.2 parts of Span-80, 0.4-0.5 parts of butyl acrylate, 0.6-0.8 parts of methacrylate, 0.1-0.2 parts of ammonium persulfate, 0.3-0.4 parts of ammonium molybdate, 0.8-1 parts of sodium fluorosilicate, 0.5-0.7 parts of lanthanum nitrate, 1.1-1.3 parts of bismuth oxide, and the balance of water. According to the lubricant disclosed by the present invention, by the ammonium molybdate, the sodium fluorosilicate, the lanthanum nitrate and the bismuth oxide, compactness of a lubricating film can be improved; adhesion between the lubricating film and a metal is increased; wear resistance is increased; and luminance and corrosion resistance of a workpiece is improved.

Description

technical field [0001] The invention relates to the technical field of forging lubricants for aluminum profiles, in particular to a water-based nanometer tungsten disulfide isothermal die forging lubricant with good wear resistance and a preparation method thereof. Background technique [0002] Isothermal die forging is a method of realizing die forging at a slower forming speed while keeping the mold and the workpiece at the same temperature. Since the workpiece is deformed at a lower strain rate at high temperature, the deformed material can be fully recrystallized, so that It overcomes the influence of work hardening, so it is very suitable for forming and processing parts with complex structures and high strength. In the process of die forging, friction will hinder the flow of metal, increase the forging load, consume deformation energy, cause uneven structure of the workpiece, dissatisfaction of the cavity filling, and reduce the service life of the die. Therefore, lubr...
