| titleOfInvention | Aliphatic polyketone lining pipe and preparation method thereof |
| abstract | The invention discloses a lining pipe prepared from aliphatic polyketone. The lining pipe is prepared from the following components: 80-100 parts of aliphatic polyketone, 1-12 parts of 2, 2-bis (4-hydroxyphenyl) propane, 3-9 parts of iodide onium salt, 10-30 parts of mica, 0.02-0.05 part of nucleating agent, 2-14 parts of erucamide, 4-16 parts of calcium carbonate, 2-13 parts of anti-aging agent and 0.7-1 part of water trapping agent. The Vicat softening temperature of the lining pipe reaches more than 200 ℃, the lining pipe shows excellent wear resistance, corrosion resistance, impact resistance, heat resistance, hydrolysis resistance and scaling resistance at the well temperature of more than 130 ℃, and the lining pipe can be applied to high-temperature oil wells in a large scale. The invention also discloses a preparation method of the lining pipe and a high-temperature-resistant oil pipe produced by using the lining pipe. |
