【摘要】：采用钠化剂Na F、Na Cl、Na_2CO_3对膨润土进行钠化改性,进一步采用十八烷基三甲基氯化铵(1831)、十八烷基二甲基苄基氯化铵(1827)、十六烷基三甲基氯化铵(1631)对膨润土进行有机改性,考察膨润土的钠化和有机改性的条件,探讨膨润土润滑脂的制备工艺。结果表明:2%~3%Na_2CO_3在60℃~80℃下钠化30~60 min的效果较好;采用十八烷基三甲基氯化铵(1831)或十八烷基二甲基苄基氯化铵(1827)与十六烷基三甲基氯化铵(1631)复合改性都取得良好效果。利用改性膨润土作为稠化剂制备的润滑脂具有良好的高温性、胶体安定性、机械安定性、防锈抗腐性、抗水性和极压抗磨性。
[Abstract]:Bentonite was modified by sodium alkyl trimethylammonium chloride 1831, octadecyl dimethyl benzyl ammonium chloride 1827, hexadecyl trimethyl ammonium chloride 1 631 by NaFU NaClN Na2CO3 modified bentonite, and bentonite was modified by alkyl trimethylammonium chloride (octadecyl trimethyl ammonium chloride, octadecyl dimethyl benzyl ammonium chloride, hexadecyl trimethyl ammonium chloride, hexadecyl trimethyl ammonium chloride). The conditions of sodium and organic modification of bentonite were investigated and the preparation process of bentonite grease was discussed. The results showed that the effect of Na2CO3 / Na2CO3 / Na2CO3 was better than that of Na2CO3 at 60 鈩，
