Abstract:
Additive for fuels and lubricants containing spherical layered structure onion-like particles, containing solvent and dispersed therein carbon nanosized spherical clusters CNOs to the extent from 1 to 500 nm; these clusters consist of laminated partially closed cockleshell-like form graphene layers with substituents; and the additive for fuels and lubricants has the following ratio of components, wt. %: * - carbon nanosized spherical clusters - 10- 6 - 10- 1 ; • - solvent - rest. Additive for fuels and lubricants is used in the capacity of antifriction, antiscoring and anti-oxidant components in the production of petroleum, bioethanol, biodiesel fuels, oils, greases and technical fluids with anticorrosive and antifrictional properties.
Abstract:
Provided are lubricant compositions and hydrocarbon fluids including one or more lubricant base stocks and an effective amount of one more zero SAP antiwear additives and/or corrosion inhibitor additives, wherein the one more antiwear and/or corrosion inhibitor additives include one or more functionalized polyolefins having one or more pyridazine moieties. Such compositions exhibit improved anti-wear, friction reduction and anti-corrosion properties.
Abstract:
A lubricant composition having an enhanced thermal conductivity, up to 80% greater than its conventional analogues, and methods of preparation for these fluids are identified. One preferred composition contains a base oil, nanomaterial, and a dispersing agent or surfactant for the purpose of stabilizing the nanomaterial. One preferred nanomaterial is a high thermal conductivity graphite, exceeding 80W/m-K in thermal conductivity. The graphite is ground, milled, or naturally prepared to obtain a mean particle size less than 500 nm (nanometer) in diameter, and preferably less than 100 nm, and most preferably less than 50 nm. The graphite is dispersed in the fluid by one or more of various methods, including ultrasonication, milling, and chemical dispersion. Carbon nanostructures such as nanotubes, nanofibrils, and nanoparticles are another type of graphitic structure useful in the present invention. Other high thermal conductivity carbon materials are also acceptable. To confer long-term stability, the use of one or more chemical dispersants or surfactants is useful. The thermal conductivity enhancement, compared to the fluid without graphite, is proportional to the amount of nanomaterials added. The graphite nanomaterials contribute to the overall fluid viscosity, partly or completely eliminating the need for viscosity index improvers and providing a very high viscosity index. Particle size and dispersing chemistry is controlled to get the desired combination of viscosity and thermal conductivity increase from the base oil while controlling the amount of temporary viscosity loss in shear fields. The resulting fluids have unique properties due to the high thermal conductivity and high viscosity index of the suspended particles, as well as their small size.
