摘要: 利用氨基硅烷偶联剂(KH-792)对松香基羟基化聚合物微球进行接枝改性,研究了反应温度、反应时间和KH-792用量对聚合物微球性能的影响。利用红外光谱(FTIR)、热重分析(TGA)、扫描电镜(SEM)和X-射线光电子能谱(XPS)对聚合物微球进行测试表征,利用电导滴定法测定了聚合物微球的氨基含量。探讨了不同氨基含量的聚合物微球对乙基紫的吸附作用。结果表明:成功制备了松香基氨基化聚合物微球,改性前后聚合物微球形态均无明显变化且球形及单分散性好,热稳定性高于松香基羟基化聚合物微球。较优制备条件为:KH-792用量为松香基羟基化聚合物微球质量的70%,在90℃下反应10h,聚合物微球氨基含量达到181μmol/g。当固液比为1 g/L,pH=9.5,在328 K下吸附5min时,微球对乙基紫的吸附量为57.02 mg/g。

Abstract: Amino silane coupling agent(KH-792) was used to modify rosin-based hydroxylated polymer microspheres,the effect of reaction temperature,reaction time,and the amount of KH-792 on the performance of the microspheres was studied. The polymer microspheres were characterized by Fourier Transform Infrared Spectroscope(FTIR),Thermogravimetry Analysis(TGA),Scanning Electron Microscope(SEM) and X-ray Photoelectron Spectroscopy(XPS),amino contents of the microspheres were tested by the conductometric titration method. The adsorption of the ethyl violet on the polymeric microspheres with different amino contents was investigated. The results showed that the rosin-based amination polymer microspheres were prepared successfully,which possessed good spherical shapes and monodispersities. The thermal stability of the polymer microspheres was higher than that of the hydroxylated polymer microspheres. The amino content of the microspheres was 181 μmol/g when the amount of KH-792 was 70%,based on the hydroxylated polymer microspheres,after reaction at 90℃ for 10h. For 5min,the maximum adsorption capacity of the microspheres to the ethyl violet was 57.02mg/g at 328K,with the ratio of the solid to liquid at 1 g/L and the pH=9.5.

Key words: silane coupling agent, amination, rosin, polymer microspheres, adsorption, ethyl violet
