【摘要】：摩擦和磨损作为一种普遍的自然现象,不仅在运行中会消耗着能量,而且会影响机械的寿命。润滑是减少摩擦、减少甚至避免磨损的一种有效手段,良好的润滑可以产生良好的社会及经济效益,减少环境影响。现代社会对生产装备、机械设施润滑的要求越来越高,各个行业特别是汽车行业也在积极推进机油的更新换代。为了制造更高等级的润滑油,必须要有良好的润滑油基础油加工技术和良好的添加剂技术。现今,为制造高等级润滑油如SM、SN等级的机油,传统的矿物润滑油基础油已显得捉襟见肘,扩大半合成乃至全合成润滑油基础油的使用量以及使用范围势在必行。本文主要根据不同环氧烷烃均聚醚的特性引入亲油性强的环氧丁烷链段,通过环氧烷烃的配比调节来控制提升醚类润滑油的不同使用性能。文中的聚醚润滑油基础油是以一元醇为起始剂,以环氧乙烷、环氧丙烷和环氧丁烷为聚合单体的三元无规共聚物。通过调节聚合单体的用量,使得润滑油基础油具有不同的理化指标和不同的适用范围。结果表明：环氧丙烷和环氧丁烷二元共聚醚在BO/PO≤4 (mol/mol)时是纯油溶性或者部分油溶性聚醚润滑油基础油,该润滑油基础油主要用于半合成润滑油基础油或者是全合成润滑油基础油；环氧乙烷、环氧丙烷和环氧丁烷合成的三元共聚醚在一定的比例下可以获得粘度指数(Ⅵ)较高、水分离性好的润滑油基础油,三者的摩尔比范围在EO/PO/BO=(0.6～1.6)/(0.33～3)/1,该种油主要用于全合成润滑油基础油；环氧乙烷、环氧丙烷和环氧丁烷三元共聚醚在环氧乙烷引入量较高时可以获得抗烃冲洗能力强的润滑油基础油,当三者质量比为EO/PO/BO=0.7/0.15/0.15具有良好的综合性能,可作为具有抗烃冲洗能力的润滑油基础油。
[Abstract]:Friction and wear, as a common natural phenomenon, not only consume energy in operation, but also affect the life of machinery. Lubrication is an effective means to reduce friction and even avoid wear. Good lubrication can produce good social and economic benefits and reduce environmental impact. In modern society, the lubricating requirements of production equipment and mechanical facilities are higher and higher, and various industries, especially the automobile industry, are also actively promoting the upgrading of oil. In order to produce higher grade lubricating oil, good lube base oil processing technology and good additive technology are necessary. Nowadays, in order to manufacture high grade lubricating oil such as SMN SN grade oil, the traditional mineral lube base oil has been overstretched. It is imperative to expand the usage and application range of semi-synthetic and even full synthetic lube base oil. According to the characteristics of different epoxy-alkanes polyether, the hydrophilic epoxy-butane segment is introduced in this paper, and the different performance of ether lubricating oil is controlled by adjusting the ratio of epoxy alkane. The polyether lube base oil is a ternary random copolymer with mono alcohol as initiator, ethylene oxide, propylene oxide and epoxy butane as monomer. By adjusting the amount of polymeric monomer, the lube base oil has different physicochemical index and different range of application. The results show that the binary copolyethers of propylene oxide and epichlorobutane are oil soluble or partially oil soluble lube base oils when BOP 鈮，
