Definitions

  • the subject of the invention is a method for manufacturing of nanocomposite graphene-like greases and a unit for the manufacture of nanocomposite graphene-like greases, which is used for the manufacturing of molybdenum disulfide or tungsten disulfide based nanocomposite greases, intended especially for the lubrication of slide bearings for heavy duty engines.
  • the type and size of the initial powder, conditions of delamination, e.g. chemical type intercalation and concentration, temperature cycle and conditions of mechanical abrasion, e.g. time and intensity of ball milling, may be changed in design in order to create various graphene-like nanoparticle materials with a wide range of thickness, width and length of the graphene plates.
  • Ball milling is known as an effective process of mass production of ultra-fine particles. Easiness of the process and wide range of properties which can be achieved using graphene-like nanoparticle materials seem to suggest that they are a material for many important technical uses. It is expected that the electronic, thermal and mechanical properties of materials made of graphene-like nanoparticles will be similar to the properties of carbon nanotubes, but graphene-like nanoparticles will be able to be manufactured at a lower cost and in higher amounts.
  • Graphene-like nanoparticles may be used as a nanoscale reinforcement of a matrix material in order to obtain a nanocomposite solid grease.
  • the expected advantages of nanoscale reinforcements in the matrix material include:
  • nanoscale fillers finely diffused in polymer or other matrix, has a very high surface area, which contributes to the effect of closing the polymer chains and may lead to better friction properties;
  • nanoscale fillers provide a very sinuous, zigzagging diffusion path, which results in an increased resistance to the permeation of humidity, oxygen, other gasses and liquid chemicals, which worsen the properties of a solid grease.
  • This sinuous structure is also an effective mechanism for the spreading of deformation energy.
  • - molybdenum disulfide or tungsten disulfide based nanoscale fillers have excellent thermal insulation properties, and connected with the matrix materials, can potentially eliminate the necessity to use a thermal protection layer, for example when used in rocket engines.
  • the essence of the invention which is a method for manufacturing of molybdenum disulfide or tungsten disulfide based nanocomposite graphene-like greases consists of creating a mixture of molybdenum disulfide or tungsten disulfide graphene-like plates with thickness below 100 nm and length below 1,0 ⁇ with liquid glue material, then the mixture is placed on a tape of the unit, to completely glue the surface of the plates with tapes, and then after passing through the tapes and breaking the plate structure, the plates are removed from the surface of the tapes.
  • This method is implemented in a unit, the essence of which consists of it being a unit of tape guiding rollers and a set of pressure rollers driven by a driving element, as well as a set of tape stretching rollers.
  • a unit for the creation of molybdenum disulfide or tungsten disulfide based nanocomposite graphene-like greases consists of a set of tape 2 guiding rollers 1 and a set of pressure rollers 4 driven by a driving element 3, as well as a set of tape stretching rollers 5.
