摘要/Abstract

摘要： 采用聚异丁烯马来酸酐、聚乙二醇为原料，二甲苯为溶剂，以小分子醇作为封端剂，通过酯化反应合成了大分子有机减摩剂，得到油溶性好、酸值低的透明样品。采用高频往复试验机、微牵引力试验机评价合成样品的减摩性能，采用旋转氧弹试验仪、差示扫描量热仪、热氧化试验仪评定合成样品的热氧化安定性，结果表明合成样品具有良好的热稳定性和减摩效果。

Abstract: A high molecular weight organic friction reducer wassynthesized through esterification reaction using polyisobutene maleic anhydride and polyethylene glycol as raw materials, xylene as solvent, and small molecule alcohol as end capping agent. Obtain transparent samples with good oilsolubility and low acid value. The anti friction performance of the synthesized sample was evaluated using HFRR high-frequency reciprocating testing machine and MTM micro traction testing machine. The thermal oxidation stability was evaluated using a rotating oxygen bomb tester, differential scanning calorimeter, and thermal oxidation tester. The results showed that thesynthesized sample had good thermal stability and high-temperature anti friction effect.

Key words: polyisobutene maleic anhydride, polyethylene glycol, macromolecule, organic friction reducer, friction coefficient, thermal stability
