International Classification:

C10M 129/78

US Classification:

508459

Abstract:

This invention is directed to a lubricant composition that is comprised of a continuous phase and a discontinuous phase, i. e. , a two phase lubricant composition. The continuous phase and the discontinuous phase of the lubricant of this invention are oil or oil type compositions that are essentially insoluble in one another. The lubricant composition is comprised of a continuous phase base oil that is comprised of a low viscosity Group II, III, IV or GTL base stock or a blend of at least two of the Group II, III, IV and GTL base stocks, optionally including a low viscosity Group V base stock, with the continuous phase base oil having, independently, a viscosity of from 1 to 100 cSt at 100 C. The lubricant composition is further comprised of a discontinuous phase that is comprised of an ester composition having a mean average droplet size of from 0. 01 microns to 20 microns, in which the ester composition is comprised of an ester compound having no ether linkages.

Abstract:

A composite high temperature insulator (A) includes a planar layer () having anisotropic thermal conductivity properties. A second planar layer () is formed from a rigid insulation material, such as a carbonized mixture of carbon fibers and a binder. The second layer is coextensive with the first layer and is preferably bonded thereto by a carbonaceous cement (). When used to insulate a heat source, such as a furnace (), convective heat is directed back to the source by the reflective surface () of the inner, anisotropic layer (). Heat which enters the anisotropic layer is dissipated evenly through the plane of the layer along a plurality of heat paths defined by a plurality of layers () of flexible graphite. Accordingly, heat which reaches the outer, second layer () results in fewer hot spots than occur with a conventional rigid insulation material, thereby reducing the total amount of insulation material required to achieve a desired level of thermal insulation.
