新型绿色极压抗磨剂的合成与性能评定

以生物质资源腰果酚为原料，经氢化、磷酸酯化合成了新型绿色极压抗磨剂双（二甲胺基）磷酸氢化腰果酚酯，采用红外光谱及核磁共振波谱等分析手段对其进行表征,并对多种极压抗磨剂在矿物基础油中的极压抗磨性能进行对比评价。结果表明：双（二甲胺基）磷酸氢化腰果酚酯具有胺基磷酸酯的结构，同时含有P、N元素，在保证较高承载性能的同时又具有较为优良的抗磨减摩性能，与其他极压抗磨剂相比，双（二甲胺基）磷酸氢化腰果酚酯具有优良的极压、抗磨和减摩性能，其综合性能优良，符合润滑油添加剂绿色化、功能化的发展趋势。

SYNTHESIS AND PERFORMANCE EVALUATION OF A NEW GREEN EXTREME PRESSURE ANTIWEAR ADDITIVE

A new green extreme pressure and antiwear agent, bis (dimethylamino) phosphate hydrogenated cardanol ester, was synthesized from cardanol. The structure of the extreme pressure antiwear agent was characterized by IR and NMR. The friction performance of the new agent in mineral baseoil was evaluated.The results showed that the hydrogenated cardanol diphosphonate had the structure of amino phosphonate and contained P and N elements, which not only ensured the high bearing capacity, but also had the excellent antiwear and friction-reduction performance. Compared with other extreme pressure and antiwear agents, bis (dimethyamine) phosphate hydrogenated cardanol ester had excellent extreme pressure, antiwear and friction-reduction performance.
