POLYMER GREASE MANUFACTURING PROCESS

摘要

A process for the manufacture of a lubricating grease composition, the process comprising steps of: (a) providing an essentially homogeneous liquid composition comprising a lubricating oil and a thickening polymer, and (b) flowing the liquid composition through a shear-mixing device to mix and cool the liquid composition to form a lubricating grease composition.

1. A process for a manufacture of a lubricating grease composition, the process comprising steps of:
providing an essentially homogeneous liquid composition comprising a lubricating oil and a thickening polymer; flowing the essentially homogeneous liquid composition through a shear-mixing device to mix and cool the essentially homogeneous liquid composition to form the lubricating grease composition, wherein the thickening polymer forms from 5 to 20 wt % of the essentially homogeneous liquid composition, wherein the liquid composition flows through the shear-mixing device along a flow-path provided with one or more temperature-controlled portions to each at least one of heat and cool the liquid composition, wherein the shear-mixing device comprises at least one pair of heat-transfer plates between which the liquid composition is flowed, wherein the surface of at least one plate is provided with surface features in a flow path of the liquid composition which act as baffles for the flow of the liquid composition, causing shear-mixing.
