Description

Method for manufacturing of nanocomposite graphene-like greases and unit for manufacturing of nanocomposite graphene-like greases
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 graphene was discovered by the scientists from The University of Manchester, led by Andre Geim and Kostyi Novoselov. Due to its great potential for the manufacturing of future electronic devices it is currently one of the main topics in physics and material science. Graphene is an excellent conductor of electricity, since besides being extremely thin and a semiconductor, electrons pass through this material with a very high speed.
The process of manufacturing of graphene-like nanoparticles in large amounts was presented in the USA patent ser. no. 10/858814 "Process for Producing Nano-scaled Graphene Plates", created by B.Z. Jang, L.X. Jang S.C. Wong and Y.J. Bai. The process covers the following stages:
- creation of the graphite powder containing small parts of graphite that are at least one dimension smaller than 200 mu.m (preferably lower than 1 mu.m);
- separation of layers of graphite crystallites in these particles in such a manner, as to completely separate from each other at least two flakes of graphene; - mechanical abrasion (e.g. ball milling) of the delaminated particles in order to reduce their size to nanoscale and, as a result, to create graphene- like nanoparticles with a thickness of plates lower than 100 nm.
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 μηι 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.
The use of the solution presented in the invention enables the following technical and utility effects:
- achieving nanocomposite plates with a thickness below 1 μιη.
- preparation of glue mixture with an initial material is not technologically complicated,
- low energy consumption of the unit drive,
- ability to pass the nanocomposite material a few times through the belts,
- ease of collecting nanocomposite material from the belts,
- low costs of constructing the unit
The subject of the invention, in an example implementation, which is not limiting, was shown using an example, whereas in order to better illustrate the invention in a schematic diagram a unit for the construction of nanocomposite material was presented, where in fig. 1 the unit in view over the main surface was shown and in fig. 2 the view over the side surface was shown.
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.
In order to create molybdenum disulfide or tungsten disulfide based nanocomposite graphene-like greases, a mixture of molybdenum disulfide or tungsten disulfide graphene-like plates with thickness below 100 nm and length below 1 ,0 μπι with liquid glue material. The mixture is then placed on the tape 2 of the unit in the zone of upper pressure rollers 4. The tape 2 driven by the driving element 3 in the zone of upper pressure losses 4 causes the gluing of the nanocomposite material to the internal surfaces of the tape 2 and fixing this glue over the segment 6 between the upper and lower pressure rollers 4. The passage of the nanocomposite material through the lower pressure rollers 4, due to the glue material adhesive will cause the particles to be disrupted into smaller parts, which is the goal of this invention. The glued material is then removed from the surface of tapes 2.
