聚合物复合材料填充剂的表面性质及其分散性的研究

STUDIES ON THE SURFACE PROPERTIES AND THE DISPERSION OF FILLER FOR POLYMER COMPOSITE

本文通过反气相色谱技术研究了未处理的、硅烷偶联剂处理的和钛酸酯偶联剂处理的三种Al(OH)_3粉末的表面性质,并通过塑化仪和扫描电子显微镜研究了Al(OH)_3填充聚丙烯体系的流变行为及其在聚丙烯中的分散效果.结果表明Al(OH)_3的表面性质对其在聚丙烯介质中的分散效果有着重要的影响.

The surface properties of untreated, silane-treated and titamate-treated Al(OH)3 filler were determined by Inverse Gas Chromatography (IGC). The rheological behavior and dispersion of A1(OH)?in polypropylene matrix war investigated by Brabender plasticorder and Scanning Electronic Microscopy, respectively. The results show that the surface properties of Al(OH)s have important in fluence on the dispersion of Al(OH)3 in polypropylene matrix.
