| 摘 要： | 根据累托石可进行阳离子交换的矿物学特征,先将天然累托石钠基化,再用氟碳表面活性剂和复合季铵盐对其进行插层改性,使有机铵阳离子进入累托石层间,并使层间距由2.41nm撑开至4.75nm,将插层改性后的累托石用作水性环氧涂料的防沉剂和流变助剂.结果表明:当插层改性累托石用量为颜填料质量的2%时,可以显著改善涂料的流平性、抗流挂性和颜填料的分散性. |

| Abstract: | According to the cation-exchange mineral characters,rectorite was first sodium-ionized modified,and then inserting-layer modified by fluorocarbon surfactant and complex quaternary ammonium salt.Organic ammonium cation enters into the layers of rectorite and makes the interlayer spacing grow from 2.41nm to 4.75nm.The modified rectorite can be used as anti-setting agent and dispersant of water-borne epoxy coatings.The results showed that when the additive mass of modified rectorite is 2% of the fillers,the characters of leveling,anti-sagging,and dispersibility of the coatings can be improved obviously. |
| Keywords: | rectorite layer-inserting leveling anti-sagging dispersibility |
