【摘要】:摩擦和磨損作為一種普遍的自然現(xiàn)象,不僅在運(yùn)行中會(huì)消耗著能量,而且會(huì)影響機(jī)械的壽命。潤滑是減少摩擦、減少甚至避免磨損的一種有效手段,良好的潤滑可以產(chǎn)生良好的社會(huì)及經(jīng)濟(jì)效益,減少環(huán)境影響。現(xiàn)代社會(huì)對(duì)生產(chǎn)裝備、機(jī)械設(shè)施潤滑的要求越來越高,各個(gè)行業(yè)特別是汽車行業(yè)也在積極推進(jìn)機(jī)油的更新?lián)Q代。為了制造更高等級(jí)的潤滑油,必須要有良好的潤滑油基礎(chǔ)油加工技術(shù)和良好的添加劑技術(shù),F(xiàn)今,為制造高等級(jí)潤滑油如SM、SN等級(jí)的機(jī)油,傳統(tǒng)的礦物潤滑油基礎(chǔ)油已顯得捉襟見肘,擴(kuò)大半合成乃至全合成潤滑油基礎(chǔ)油的使用量以及使用范圍勢在必行。本文主要根據(jù)不同環(huán)氧烷烴均聚醚的特性引入親油性強(qiáng)的環(huán)氧丁烷鏈段,通過環(huán)氧烷烴的配比調(diào)節(jié)來控制提升醚類潤滑油的不同使用性能。文中的聚醚潤滑油基礎(chǔ)油是以一元醇為起始劑,以環(huán)氧乙烷、環(huán)氧丙烷和環(huán)氧丁烷為聚合單體的三元無規(guī)共聚物。通過調(diào)節(jié)聚合單體的用量,使得潤滑油基礎(chǔ)油具有不同的理化指標(biāo)和不同的適用范圍。結(jié)果表明:環(huán)氧丙烷和環(huán)氧丁烷二元共聚醚在BO/PO≤4 (mol/mol)時(shí)是純油溶性或者部分油溶性聚醚潤滑油基礎(chǔ)油,該潤滑油基礎(chǔ)油主要用于半合成潤滑油基礎(chǔ)油或者是全合成潤滑油基礎(chǔ)油;環(huán)氧乙烷、環(huán)氧丙烷和環(huán)氧丁烷合成的三元共聚醚在一定的比例下可以獲得粘度指數(shù)(Ⅵ)較高、水分離性好的潤滑油基礎(chǔ)油,三者的摩爾比范圍在EO/PO/BO=(0.6~1.6)/(0.33~3)/1,該種油主要用于全合成潤滑油基礎(chǔ)油;環(huán)氧乙烷、環(huán)氧丙烷和環(huán)氧丁烷三元共聚醚在環(huán)氧乙烷引入量較高時(shí)可以獲得抗烴沖洗能力強(qiáng)的潤滑油基礎(chǔ)油,當(dāng)三者質(zhì)量比為EO/PO/BO=0.7/0.15/0.15具有良好的綜合性能,可作為具有抗烴沖洗能力的潤滑油基礎(chǔ)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,
