| 摘 要： | 以新疆夏子街钠基膨润土为原矿,研究湿法提纯工艺方法。研究表明:PRT-3土样提纯,可制备高纯膨润土;PRT-2土样提纯后,进行了有机化改性及结构表征。当HDTMA(D1631、CTAB)的用量在110mmol/100g土时,两种改性有机膨润土的黏度值均达最大。不同碳链长度的有机季铵盐插层反应表明,C16有机季铵盐(HDTMA)改性效果较优。通过涂料用膨润土性能测定,表明有机膨润土各项性能优良。

| Abstract: | With the samples from Xiazijie sodium-base bentonite of Xinjiang,it was shown that the wet purification effect of PRT-3 was better,and the PRT-3 bentonite was able prepared to the hi gh purification bentonite.After purification of PRT-2,organization and charac terization of purified bentonite were invistigated.When the ratio between HDTMA(D1631 and CTAB) and bentonite was 110mmol/100g,the viscosity of two kinds of organobentonite were the top.It was proved that the modification effect of HDT MA was better by intercalation reaction with different carbon chain length.By the determination of dope performance with organobentonite,it was shown that the performance of organobentonite was excellent in dope. |
