| titleOfInvention | A kind of low freezing point diesel oil lubrication improver and its application |
| abstract | The present invention relates to a low freezing point diesel oil lubrication improver and application. The low freezing point diesel oil lubrication improver is composed of oligomeric olefin paraffin oil and pentaerythritol ester, and the mass ratio of oligomeric olefin paraffin oil and pentaerythritol ester is ( 1-5): (5-1), the freezing point of the oligoolefin paraffin oil is -50～-60°C. The freezing point of the diesel lubrication improver of the present invention is ‑40～‑50°C, which is far lower than the freezing point of commercially available acid-type and ester-type diesel lubrication improvers, and the acid value is low, less than 2.5. The diesel lubricating improver of the invention is composed of oligomeric olefin paraffin oil and pentaerythritol ester. The oligomeric olefin paraffin oil has intramolecular double bonds, which can play a certain lubricating effect and increase the lubricating performance. The pentaerythritol ester itself has lubricating performance, In addition, the oligomeric olefin paraffin oil improves the solubility of pentaerythritol ester in diesel oil, improves the lubricity to a certain extent, and greatly improves the lubricating performance of diesel oil. |
