高载荷低腐蚀极压抗磨剂的研制
|
摘要
合成了一种高载荷低腐蚀极压抗磨剂,进行了结构表征并将其添加到多元醇酯类基础油中进行性能评定。与各类商品极压抗磨剂进行了性能对比,重点考察了承载能力与腐蚀和氧化安定性。结果表明,所研制的极压抗磨剂具有优良的腐蚀和氧化安定性、热稳定性以及优异的承载能力和润滑性能。制定了产品指标并进行了批次稳定性考察,结果表明批次稳定性良好。
A kind of high load and low corrosion extreme pressure antiwear additives was synthesized and characterized by IR and elementary analysis.It was added to the base oil of polyol esters for performance evaluation to investigate their load-carrying properties,corrosion and oxidation stability.The results were compared with those of commercial products.The results showed that the developed additive was better than the compared ones in corrosion and oxidation stability as well as thermal stability,especially in load-carrying properties and lubricating property.The product specifications were formulated and batch stability was studied.
