Abstract

The invention discloses a water-based nano tungsten disulfide lubricating agent capable of protecting the surface of an aluminum profile and used for isothermal die forging and a preparation method of the water-based nano tungsten disulfide lubricating agent. The water-based nano tungsten disulfide lubricating agent is prepared from raw materials in parts by weight as follows: 7.4-7.6 parts by weight of PAO6 (poly-alpha-olefin), 0.2-0.25 parts of a silane coupling agent kh 560, 8.2-8.4 parts of nano tungsten disulfide, 0.8-1 part of nano carbon balls, 0.8-1 part of nano bentonite, 1-1.2 parts of Span-80, 0.4-0.5 parts of butyl acrylate, 0.6-0.8 parts of methyl acrylate, 0.1-0.2 parts of ammonium persulfate, 0.8-0.9 parts of barium fluoride, 0.3-0.4 parts of nano TiO2, 0.5-0.6 parts of tetraethoxysilane, 0.5-0.6 parts of micron TiO2 and the balance of water. The lubricating agent has an excellent protection function on the surface of the aluminum profile through comprehensive use of barium fluoride, nano TiO2, tetraethoxysilane and micron TiO2 and has better friction reduction and abrasion resistance by comparison with ordinary water-based lubricating agents.

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 for protecting the surface of aluminum profiles 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 th...
