【摘要】：隨著世界性能源危機(jī)的出現(xiàn)和社會(huì)對(duì)環(huán)保的重視,水基潤滑液得到迅速的發(fā)展；水基潤滑液將在工業(yè)領(lǐng)域發(fā)揮著越來越大的作用。本文將月桂酸無規(guī)共聚醚(Lauric acid random copoly-ether, LPE)和硼酸三乙醇胺(Boric acid triethanolamine,BN)按質(zhì)量比1：1混合配制成水基潤滑液(BN-LPE);以LPE水溶液為參照組,對(duì)BN-LPE水溶液進(jìn)行減摩抗磨性能、流變性能及成膜性能分析并做機(jī)理分析。 利用四球摩擦磨損試驗(yàn)機(jī)對(duì)潤滑液的減摩抗磨性能進(jìn)行評(píng)價(jià)分析。分別考慮濃度、載荷和轉(zhuǎn)速對(duì)潤滑液減摩抗磨性能的影響；利用X射線光電子能譜儀(X-ray photoelectron spectroscopy instrument, XPS)分析出磨痕表面的生成物成分；利用Micro XAM型三維共聚焦表面形貌儀對(duì)磨痕表面進(jìn)行形貌分析。研究發(fā)現(xiàn)BN-LPE水溶液具有良好的減摩抗磨性能,其減摩性能隨濃度的增加而增強(qiáng)；濃度在15%-35%時(shí),其平均摩擦系數(shù)在0.03左右；最低摩擦系數(shù)達(dá)到0.005左右。分析原因是硼酸三乙醇胺分解后和月桂酸無規(guī)共聚醚或其基團(tuán)反應(yīng)生成新的硼酸酯,吸附在金屬表面形成致密的化學(xué)反應(yīng)膜從而起到有效的減摩抗磨性能。 利用Physica MCR301旋轉(zhuǎn)流變儀對(duì)BN-LPE水溶液做流變性能分析,得出不同質(zhì)量濃度和溫度下BN-LPE水溶液的動(dòng)力粘度和剪切率之問的關(guān)系曲線。經(jīng)分析得出BN-LPE水溶液的動(dòng)力粘度較小,這可能是其減摩性能良好的原因。 選擇半浸泡的潤滑方式,利用NGY-6納米級(jí)潤滑膜厚度測(cè)量儀對(duì)BN-LPE水溶液的成膜性能進(jìn)行研究,分別考慮濃度、載荷和線速度對(duì)成膜性能的影響。研究發(fā)現(xiàn)：BN-LPE水溶液的成膜性能在高載荷下較穩(wěn)定并有一定的承載能力；隨著載荷的增大,線速度對(duì)成膜性能的影響越��；經(jīng)分析該潤滑液在試驗(yàn)中可能形成了化學(xué)吸附膜。 本文研究的含氮硼酸酯在聚醚水溶液中的摩擦學(xué)性能,經(jīng)試驗(yàn)表明該水基潤滑液具有良好的減摩抗磨性能,具有很好的工業(yè)應(yīng)用前景。圖61幅,表7個(gè),參考文獻(xiàn)67篇。
[Abstract]:With the emergence of world energy crisis and the importance of society to environmental protection , water - based lubricating liquid has been developed rapidly . Water - based lubricating liquid will play an increasingly important role in the field of industry . In this paper , Lauric acid random copoly - ether ( LPE ) and boric acid triethanolamine ( BN ) are mixed into water - based lubricating liquid ( BN - LPE ) according to the mass ratio of 1 : 1 . The effects of concentration , load and rotational speed on the wear resistance of lubricating liquid were analyzed . The results showed that the wear resistance of BN - LPE aqueous solution increased with increasing concentration , and the friction coefficient reached about 0 . 005 when the concentration was 15 % -35 % . The relationship between the dynamic viscosity and shear rate of BN - LPE aqueous solution under different mass concentration and temperature was obtained by using a Physica MCR301 rotary rheometer . The results show that the dynamic viscosity of BN - LPE aqueous solution is small , which may be the reason for its good antifriction performance . The film - forming properties of BN - LPE aqueous solution were studied by means of NGY - 6 nano - lubricating film thickness measuring instrument . The results showed that the film - forming properties of BN - LPE aqueous solution were stable under high load and had certain load - bearing capacity , and the effect of linear velocity on film - forming performance was smaller with the increase of load . The tribological properties of the nitrogen - containing borate ester in polyether aqueous solution are studied . The results show that the water - based lubricating liquid has good anti - friction and anti - wear properties , and has good industrial application prospect .
