节能减摩添加剂和润滑油的进展

节能减摩添加剂和润滑油一直是大家所关心的问题，长期以来，国内外润滑油工作者围绕着生产、使用高效节能减摩添加剂，进行了大量卓有成效的工作，也获得了一定进展，如进行了油品低粘度化的研究，研制了一批节能减摩剂等等。但以前推广的节能减摩剂在推广中常常遇到一个致命的经济问题，即节油不节钱，甚．至节约的油钱还抵不上买添加剂的钱。故推广起来步履瞒珊，踏步不前，因此，寻找一种原料来源易得、生产成本低廉、节能效果明显、经济效益显著的添加剂和润滑油一直是大家追求的目标。青岛飞驰润滑油密封材料公司（以下简称飞驰公司）…

Multifunctional Additives Viscosity Index Improvers,Pour Point Depressants and Dispersants for Lube Oil

Abstract

In the present work, some polymeric additives based on styrene-maleic anhydride copolymer were prepared and evaluated as multifunction lube oil additives (viscosity index improvers, pour point depressants, and detergent-dispersant additives). The styrene-maleic anhydride copolymer reacted with different alcohols (dodecyl alcohol, hexadecyl alcohol, octadecyl alcohol, and docosanol) to prepare four different types of esters and aminated with different types of amines (dodecyl amine, hexadecyl amine, and octadecyl amine) to prepare another three co-polymeric additives. Structure of the prepared compounds was confirmed by I.R. spectroscopy. The molecular weights of the prepared copolymers were determined by using gel permeation chromatograph and the percentage of esterification and amination were determined by ¹HNMR. The efficiencies of the prepared compounds as viscosity index improvers, pour point depressants, and detergents-dispersants were investigated. It was found that the efficiency of the prepared compound as viscosity index improvers increases with increasing the concentration of additives in the solution and with increasing the molecular weight of prepared compounds, while the efficiency of the prepared compounds as pour point depressants increases with decreasing the concentration of the prepared polymers. On the other hand, the prepared compounds showed excellent dispersion power.

Synthesis and Evaluation of Some Polymeric Compounds as Pour Point Depressants and Viscosity Index Improvers for Lube Oil

Abstract

In the present study, some polymeric additives were prepared and used as pour point depressants and as viscosity index improvers for lube oil via copolymerization of maleic anhydride and vinyl acetate with different esters of acrylic acid. The molecular weights of the prepared copolymers were determined by GPC. The efficiency of the prepared compounds as pour point depressant and viscosity index improvers was investigated. It was found that the efficiency of the prepared compounds as pour point depressant increases with decreasing the concentration of the prepared polymers, increasing the chain length of alkyl groups, and increases with decreasing the molecular weight. The efficiency of the prepared compounds as viscosity index improvers increases by increasing the concentration of these additives and by increasing the molecular weight of the polymer.

The Rheological Properties of Lube Oil With Terpolymeric Additives

Twelve terpolymeric additives were prepared via free radical chain addition polymerization. The rheological properties of lube oil (SAE-30) were studied with and without additives. The prepared terpolymers have a good effect on the viscosity-temperature relationship. The flow curves and viscosity-shear rate curves of the prepared additives doped with lube oil were studied and it was found that they behave as Bingham fluids. The sensitivity of the prepared terpolymers to mechanical stresses was studied and it was found that the sensitivity increases with increasing the molecular weight of the prepared additives.
