POLYMER THICKENED GREASE COMPOSITION AND METHOD FOR MAKING THE SAME |
| 摘要 |
A method for preparing a final grease product comprising steps of: (a) mixing a polymeric thickener, which comprises a polymer of propylene, and a lubricating base oil at a temperature above the melting point of the polymeric thickener, wherein the polymeric thickener is present in an amount of 11.5-15.5 wt %, based on the total weight of the mixture so obtained; (b) cooling the mixture as obtained in step (a); (c) subjecting the cooled mixture as obtained in step (b) to a first mechanical treatment, to obtain an intermediate grease; (d) subjecting the intermediate grease as obtained in step (c) to a second mechanical treatment, carried out at a temperature in the range of from 50-90° C., to obtain the final grease product. The method can be applied to manufacturing of a grease. |

1. A method for preparing a final grease product comprising steps of:
(a) mixing a polymeric thickener, which comprises a polymer of propylene, and a lubricating base oil at a temperature above the melting point of the polymeric thickener, wherein the polymeric thickener is present in an amount of 11.5-15.5 wt %, based on the total weight of the mixture so obtained; (b) cooling the mixture as obtained in step (a); (c) subjecting the cooled mixture as obtained in step (b) to a first mechanical treatment, to obtain an intermediate grease; (d) subjecting the intermediate grease as obtained in step (c) to a second mechanical treatment, carried out at a temperature in the range of from 50-90° C., to obtain the final grease product. |
