【摘要】：以異丙醇鋁為原料制備復(fù)合鋁基潤滑脂,考察最高煉制溫度、皂化有機(jī)酸的反應(yīng)順序、急冷油加入量、復(fù)合鋁皂稠化劑的組成、基礎(chǔ)油種類等對復(fù)合鋁基潤滑脂理化性能的影響;通過紅外光譜分析手段監(jiān)控研究復(fù)合鋁皂的生成和復(fù)合鋁基潤滑脂的制備過程;根據(jù)實驗得到的最佳生產(chǎn)工藝和配方,在中型裝置上進(jìn)行放大試驗。結(jié)果表明:復(fù)合鋁基潤滑脂的最佳制備條件為基礎(chǔ)油選擇150BS,用1/3質(zhì)量的150BS作急冷油,硬脂酸和苯甲酸同時與異丙醇鋁反應(yīng),硬脂酸、苯甲酸、異丙醇鋁的摩爾比為1∶1∶1.2,最高煉制溫度控制在180~190℃;利用紅外光譜分析可以很好地監(jiān)測該制備過程;所研制的復(fù)合鋁基潤滑脂產(chǎn)品具有良好的機(jī)械安定性、膠體安定性、防腐防銹性、抗水性和抗磨性,可滿足美國海軍艦船用潤滑脂A-A-50433規(guī)范要求。
[Abstract]:The compound aluminium base grease was prepared from aluminium isopropanol. The highest refining temperature, the reaction order of saponification organic acid, the quantity of quenched oil, the composition of compound aluminum soap thickener were investigated. The effects of base oil types on the physical and chemical properties of composite alumin-based grease; monitoring and studying the formation of composite aluminum soap and the preparation process of composite alumin-based grease by means of infrared spectrum analysis; and the optimum production process and formula according to the experiment, An amplification test is carried out on a medium installation. The results showed that the optimum preparation conditions of composite aluminium base grease were as follows: base oil 150BS, 150BS of 1 / 3 mass as quench oil, stearic acid and benzoic acid reacting with aluminium isopropanol, stearic acid, benzoic acid, etc. The molar ratio of aluminum isopropanol is 1: 1: 1.2, and the highest refining temperature is controlled at 180 ~ 190 鈩，
