硅烷偶联剂改性粉煤灰基白炭黑及其分散性能
|
摘要
采用3种硅烷偶联剂3-氨丙基三乙氧基硅烷(APTES)、3-巯丙基三乙氧基硅烷(MPTES)与3-(2,3-环氧丙氧)丙基三乙氧基硅烷(GPTES)对粉煤灰基白炭黑进行表面改性。借助FTIR、TGA、Zeta电位仪和SEM考察并比较了氨基、巯基、环氧类硅烷偶联剂对改性白炭黑分散性能的影响。结果表明,3种硅烷偶联剂均可接枝于白炭黑表面,且改性后白炭黑粒子分散性得到明显改善。分散性不仅与改性后白炭黑产品粒径相关,而且与硅烷偶联剂的负载量有一定关联。其中,MPTES对白炭黑的改性效果最佳,当pH为10、MPTES/SiO_2物质的量比为1.0∶1.0时,得到的改性白炭黑在乙醇中的分散性最好,粒径为557 nm,Zeta电位绝对值为36.43 mV。
Three silane coupling agents, 3-(aminopropyl)triethoxysilane(APTES), 3-(mercaptopropyl)-triethoxysilane(MPTES) and 3-glycidoxypropytriethoxysilane(GPTES) were used to modify the white carbon black derived from fly ash. The effects of amino, thiol and epoxy silane coupling agents on the dispersion of modified white carbon black were studied by FTIR, TGA, Zeta potentiometer and SEM. The results showed that three different silane coupling agents were grafted successfully onto the surface of white carbon black. The dispersity of modified white carbon black was improved obviously, which was related not only to the particle size of modified white carbon black but also to the loading amounts of silane coupling agents. Among them, the modification effect of MPTES was the best. Under the conditions of pH=10 and n(MPTES)∶n(SiO_2)=1.0∶1.0, the obtained product had the best dispersity in alcohol, the size was 557 nm and the absolute value of zeta potential was 36.43 mV.
